Jiangsu Yunuo Cooling Technology introduces closed cooling tower manufacturers to talk about why closed cooling towers leak water? What is the reason?
The working principle of the closed cooling tower is mainly based on the evaporative cooling technology, and its design comes from the evaporative cooler used in industry. The high temperature water of the condenser, absorber or process equipment is sent to the cooling coil of the cooling tower through the pressure generated by the water pump or other pressure equipment, and the circulating water enters the cooling tower. The closed cooling tower manufacturer exchanges heat through the movement in the cooling tower and through contact with the air fluid, and the return water after entering the cooling tower passes through the pressure swirl nozzle equipment installed on the top of the tower and the upper part of the air duct. A high-speed straight and downward movement of spray droplets is formed, completing the mission of adding the surface area of the water droplets. The water film and the air form a full steam of moist heat. The fans emit heat to the atmosphere, and some of the water droplets are recovered by the sump to reduce the loss of spray water.
In the process of water droplets, the water droplets will also encounter the rising airflow, thereby delaying the falling rate of the water particles and prolonging the heat exchange time. The heat of the fluid is first transferred to the inner wall of the copper tube, then from the inner wall to the outer wall of the copper tube, and then to the water spray film. When the water spray is reduced to a certain amount, the float valve actively makes up for the water, so that the cycle continues. In addition, because the cooling tower removes the packing and becomes an empty tower, the resistance in the tower is reduced. Under the action of the fan, the wind speed and air volume are increased, and the air-water ratio is added to achieve the intention of improving the cooling effect. Fluid cooling tower machines should avoid acid gas, explosive dust, severe smoke and excess water vapor; be placed around the building and at a satisfactory distance (0.7m, depending on the model) from the air inlet; on the wall of the well When placing, attention should be paid to the heat release caused by the return of hot and humid air, and ventilation equipment can be considered in special circumstances;
First of all, there is water leakage at the connection between the tower body and the water basin. When assembling the closed cooling tower, glue is used between the galvanized plates to be compacted and sealed. Long-term operation, under the impact of spray water, deformation of the basin body, drop of sealant, etc., will cause water leakage at the joint. Because the spray water will be collected in the bottom pool, the leaking water needs to be continuously compensated for the spray water. Secondly, the connection pipeline leaks. When the pipe is laid, some flanges and elbows will be connected. When the connection is made, a sealing ring will be added between the two connecting joints, and the pipeline leaks. Most of the reasons are the pipe The road connection is not dense, the sealing ring is damaged or the position is displaced, which will cause the sealing to be weak and cause water leakage. In addition, the water collecting tank is corroded and leaked. Because of long-term use, it may also be the environment and water quality caused by the high pH of the water used to corrode the material of the water collecting tank, and the thickness of the box body is not uniform. Damaged water leaks will occur. Water leakage will increase water consumption, increase environmental pollution, and then accelerate the corrosion of other components, a vicious circle.
The above is the relevant content introduced by Jiangsu Yunuo Cooling Technology.
