There is a lot of floating water in the cooling tower. What are the control measures we can take?

Jiangsu Yunuo Cooling Technology will introduce to you the control measures that we can take for a lot of floating water in cooling towers. As a kind of cooling equipment that is particularly popular in recent years, cooling tower has the significant advantages of high efficiency, low energy consumption, high cost performance, and its flow rate drift rate is controlled within a reasonable range. Compared with the open cooling tower, the work efficiency is improved, the cost is reduced, and it is environmentally friendly. Several causes and control measures for a lot of floating water in closed cooling towers, there are problems with the water collector. There is a water collector at the bottom of the fan, which is specially designed to recover the water in the flowing gas. If the amount of floating water increases, it is necessary to first consider the difficulty of the water collector. If the new equipment is obviously not suitable for the equipment collector ring, the internal gap is large, and the viewpoint is not suitable. When the equipment is outdated, the aging of the collector should be considered. Aging will cause water accumulation in the water collector, local damage, unstable and loose installation standards. As a result, the catchment volume is reduced and the drifting speed is accelerated. The fan has a large air volume. The fan power is large, the wind force is large, and the air volume of the selected supporting equipment is obviously fast. After the hot and humid gas passes through the water collector, the moisture in the gas will be quickly discharged. If not collected immediately, a lot of cooling circulating water will be pumped out through cooling water. fan. In this case, consider removing the fan to adjust the viewing angle of the fan blades. Fan speed is too low. It is well known that closed cooling towers have intake grills on the side or at the bottom. Air enters and gas inflow occurs. If the air volume of the fan is small, the air intake force to generate the airflow will be larger; if it is smaller, the water in the hot and humid air will quickly move out of the grille, which will also cause a high drift rate. Excessive water spray from the bottom. The closed cooling tower has a water storage tank at the bottom, and this water storage tank is close to the air intake grille. If there is a large amount of water in the pool, the rapidly descending spray can land on the surface of the pool and cause splashing. Water, splashing water droplets will immediately penetrate the grille to the outside of the enclosed cooling tower. According to this, we generally establish a water supply line first, and then supply the spray water when the amount of water spray is lower than the water supply line for reasonable control.

Closed-circuit cooling tower manufacturers talk about the future development of closed-circuit cooling towers

Jiangsu Yunuo Cooling Technology will introduce the closed-circuit cooling tower manufacturers to talk about the future development of closed-circuit cooling towers. Cooling tower is the more common equipment factory, the factory is mainly used for temperature cooling to create a good production space. In the process of development, cooling towers have appeared in more forms, such as closed cooling towers and closed cooling towers, each of which has a great advantage. The development of closed cooling tower The closed cooling tower cooling tower is a new display form, which can further play the role of cooling. Compared with the traditional cooling tower, the closed cooling tower has a layer of glass fiber reinforced plastic on the surface. It can have a good protective effect and can improve the cooling effect of the equipment. Cooling towers are very suitable for the needs of this era and can better respond to the needs of users for larger-scale production. How to price a cooling tower Since the market offers a new choice of cooling towers, you are definitely more focused on the price of this cooling tower. In different equipment, you want to get more advantages and first have to pay a higher price for the fluid cooling tower. From a cost point of view, the fluid cooling tower is more expensive than the price of the traditional cooling tower, but the effect and efficiency of the traditional cooling tower are the same, and we can consider the option. Closed-circuit cooling tower manufacturers have the future. Closed-circuit cooling towers are very popular now, but I don't know that in the future development process, there will be other new cooling towers to replace the position of closed-circuit cooling towers. At least from the current situation, the closed circuit cooling tower can still play a huge role in the next five years or more. Now the cooling tower fan has a variety of functions, which can meet the various practical needs of users. In the process of meeting demand, we can achieve better cooling needs through related equipment. With this process, we don't have to look forward to it all the time. It will be easier for everyone to do it later because the relevant needs have already been met. Especially in this day and age, such devices are increasingly needed to function. But what will happen during the future use of cooling towers is unclear. Are Fluid Cooling Towers Expensive? After many people know about the effects of fluid cooling towers, they now wonder if cooling towers are expensive. In fact, the price is slightly higher than that of traditional cooling towers and closed cooling towers, and there is almost no obvious gap. But the difference is that when using a closed cooling tower, the user needs to use a certain material to meet the actual cooling needs and roles. A series of problems with every new cooling tower. These problems bring you a lot of trouble and will promote the emergence of new cooling towers as soon as possible. At least from the current industry situation, closed-circuit cooling towers can meet the relevant needs of users. In recent years, this also means that closed-circuit cooling towers have a future. The above is the relevant content introduced by Jiangsu Yunuo Cooling Technology.

Why the cooling effect of the closed cooling tower is not good

Jiangsu Yunuo Cooling Technology will introduce to you why the cooling effect of the closed cooling tower is not good. In recent years, closed cooling towers have been widely used in air conditioning equipment and production technology. The initial investment of the equipment may be larger than that of the open tower, but the cooling effect is good, mainly saving water and electricity, and the operation of the equipment can benefit for a long time. At the same time, it has the same investment as the traditional open tower, water collecting tank and heat exchanger, but the equipment is more compact, higher specification, more energy-saving and more environmentally friendly, which is loved by customers. The closed cooling tower is the cooling circulating water. The seepage water of the closed cooling tower must be cleaned and cleaned, and the remaining iron filings, stains and dirt must be avoided. The sprinkler head should be replaced and replaced, which will damage the actual effect of drainage and the shower. The above conditions should be cleaned up immediately, otherwise the actual effect of cooling will be reduced. The suspended solid content of the cooling circulating water is generally adjusted below 50mg/l. When the pollution concentration value increases, a small amount of bleaching solution or other water body modifiers should be added as much as possible to solve the problem, and beware of stains that have been operated for a long time. The closed loop heat exchanger is implemented in the system software. The cooling circulating water after the water cooling process medium is heated is still not in the closed system software that touches the air immediately. After the temperature of the equipment or air-cooled heating equipment drops, the water circulation cooling process medium circulation system is used. An open cooling tower means that the cooling water passes through the heat exchange equipment, the water temperature rises, and then passes through the cooling tower to directly contact the atmosphere. The temperature of the water is cooled down by transpiration, and the heat is released into the surrounding atmosphere. The cooling water is transported from the beginning to the process heat exchange equipment by the water pump, and then circulates back and forth. The bearing end cover of the motor needs to be oiled once a year; the reducer should be careful to prevent the operation of the vacuum pump (low oil volume), and often pay attention to improve (the horizontal transmission system uses N100 or 150 light-load industrial gear oil, the vertical transmission system Add general industrial gear oil 20#--50# to lubricate), after one year of continuous operation, it should be replaced with new oil. Assuming that there are two rotating shafts of the fan, the bearing with a seat in the middle should be lubricated monthly. The oil leakage of the piping system software such as the rotating shaft, the ductile ring of the coupling, and the friction plate should be removed and replaced immediately. The reduction of the motor speed ratio is also detrimental to the actual effect of cooling. If there is any abnormality in the centrifugal fan system software, it should be parked immediately for inspection, fault detection, and the cutter head should be washed and damaged according to the detailed conditions. In the whole process of the application of the closed cooling tower, if it is found that there is too much water outflow, the water should be filled with the tap water dynamic replenisher immediately. In addition, it is necessary to check whether the water filter is damaged, and repair the water leakage and water storage tank damaged by the anti-corrosion of glass fiber reinforced plastic. seepage. The inside and outside of the closed cooling tower need to be cleaned once a year to prevent the accumulation of waste and damage the flow of water in and out. The above is the relevant content introduced by Jiangsu Yunuo Cooling Technology.

What is the cooling efficiency of the closed cooling tower related to?

Jiangsu Yunuo Cooling Technology introduced to us what the cooling power of the closed cooling tower is related to. The service life of each type of equipment is limited, and the closed cooling tower is no exception, but it should be completed on the basis of proper maintenance, otherwise its cooling performance may also be affected. Now that the cooling power has been mentioned, it is necessary to understand its determining factors. In addition to maintenance, what else will affect the cooling power of the closed cooling tower. The first thing that comes to mind is the amount of spray water, but when the amount of water is reduced, the heat dissipation of the equipment will also be reduced. After a similar phenomenon occurs, it is necessary to check whether the supply pressure of the pump is stable; whether there is an air phenomenon; whether there is a blockage, etc. At the same time, the fan and air volume are also one of the factors that determine the cooling power, so they are also the key to inspection. Closed cooling towers Under normal conditions, closed cooling towers need to be installed in a ventilated place, which shows the importance of the environment to it. Therefore, try to prevent some constructive operations around the cooling tower after installation, which will affect the ventilation environment of the cooling tower. . In addition, the scale and the spray system must also have an impact, so it is necessary to prevent the generation of scale and ensure the normal operation of the spray system. The water distribution system is not easy to block, the water filling is kept clean and not easy to age, the moisture backflow is small, and the method of preventing freezing and deicing is simpler. Multiple units can be designed in combination. In winter, the required water temperature and water volume can be combined with a single unit to operate or all fans can be turned off. The maintenance of the construction device is simple and the cost is low, and it is commonly used in air conditioners and industrial large and medium-sized cooling circulating water. Cross-flow tower, the water is filled in the tower, the water flows from top to bottom, and the air flows horizontally from the outside of the tower to the inside of the tower. The two flow directions are vertical and orthogonal to a cooling tower. Commonly used in residential areas with strict noise requirements, it is a cooling cycle tower that is widely used in the air-conditioning industry. Advantages: energy saving, low water pressure, small wind resistance, also equipped with low-speed motor, no dripping noise and wind noise, easy maintenance of filling and water distribution system. Multiple cooling towers can be constructed and placed at will according to the building shape, and single or multiple cooling towers can be activated according to the required water temperature. It should be noted that the frame needs 40% more heat exchange to have more filler volume, the filler is easy to age, the water distribution hole is easy to block, the anti-icing is not good, and the moisture backflow is large. The advantage of a cross-flow tower is the disadvantage of a counter-flow tower. For the spray-ventilated cooling tower without packing, the common spray nozzle is installed at the air inlet at the bottom of the closed cooling tower. When the hot water passes through the inner swirling vane of the nozzle, the inner swirling flow is formed to form a fine atomization and sprayed out, so that the mist exists, and it is sprayed upwards and flows downwards. The atomization is uniform without hollowing phenomenon, the cooling effect is stable, the power consumption is low, the water drift rate is 0.01%, no filler, the cost is low, and the service life is long, which conforms to the GB7190.1-1997 standard. Application range of metallurgy, food, chemical industry, high turbidity, high temperature, anti-corrosion cooling tower. The above is the relevant content introduced to us by Jiangsu Yunuo Cooling Technology.

How to complete the waste heat recovery and utilization of cooling towers

Jiangsu Yunuo Cooling Technology introduces how to complete the waste heat recovery and utilization of cooling towers. Choosing the correct orientation device for the cooling tower can fundamentally ensure that the cooling tower can exert its calibrated cooling capacity. Its main purpose is to place the cooling tower in a position where the fresh air can enter the unit freely and without obstacles, and ensure a certain degree of reduction of backflow. One step in achieving this is to consider the various factors that may affect the cooling tower installation. After mastering these materials, the installation position of the sewage cooling tower can be correctly selected. Under normal circumstances, the cooling tower of the factory will be installed on the roof or other building floors, and has a satisfactory bearing capacity. Because of the excellent ventilation, the cooling tower helps to effectively dissipate heat, but we need to pay attention that during the installation process, the distance between the cooling tower inlet and the building should be at least 1.5 times the outer diameter of the tower, which can To meet the requirements of the new wind vane, it does not need to be installed on a high wall without ventilation. If you choose the installation location of the cooling tower, you should pay attention to whether there is soot or dust, and do not install it in this place to avoid being blocked by soot and dust. The working principle of the cooling tower is that the ventilated air is blown from the correct viewpoint to the dripping water. When the air passes through these water droplets, some of the water will be evaporated, because the heat used to evaporate the water droplets reduces the temperature of the water, and the remaining water will be cooled. The cooling effect of this method relies on the relative humidity and pressure of the air. When the water droplets come into contact with the air, on the one hand, there is no direct heat transfer between the air and the water, and on the other hand, there is a certain pressure difference between the surface of the water vapor and the air. Taking away is the heat transfer by transpiration, so as to achieve the purpose of cooling. The cooling tower can exchange the cooling water carrying waste heat with the air inside the tower body, so that the waste heat is transferred to the air and dissipated into the atmosphere. Now the cooling tower is used more and more widely, and the cooling tower can complete the waste heat recovery to Take boiler hot water as an example. After the water is heated, it will form relatively high-temperature high-pressure steam to drive a steam turbine to generate electricity. The flue gas is then discharged into a condenser, and with the aid of a cooling tower, the flue gas is converted into water, which is then returned to the boiler for recovery. In this process, the waste heat will transfer heat with the cooling water in the cooling tower, and the water temperature will increase. At the same time, the large amount of heat energy generated above can also be transferred to the air, so if other equipment is equipped, it may have a greater effect. The cooling tower can act through the heat conduction between the circulating cooling water and the cold and dry air, and only after the transpiration of the circulating cooling water can the latent heat of gasification be removed, so as to achieve the purpose of lowering the water temperature. That is to say, when the cooling tower is running, it needs a certain pressure cycle to complete. The above is the relevant content introduced to us by Jiangsu Yunuo Cooling Technology.
