Detailed methods for improving closed cooling tower noise

In the environment is very important, noise pollution or environmental pollution are unforgivable things, especially noise. Before, noise pollution was not regarded as an indicator of environmental pollution, but with the rise of people's living habits, noise has become a problem. This kind of hateful pollution, so manufacturers pay great attention to the methods of improving noise, such as how to improve the noise problem of closed cooling towers.
Everyone knows that the closed cooling tower is a machine that is easy to generate noise. The rumbling is very harsh, and the noise of the closed cooling tower is also very penetrating. How to improve the noise of the closed cooling tower? First of all, everyone will definitely I wonder if the sound of the machine is because the motive is too loud. Yes, the sound of the engine must be controlled. For example, can some mufflers be used, but make sure that the heat of the engine can be dissipated, or the engine will burn out, which cannot be solved. There will be a lot to lose. Of course, we can add shock-proof sheets to the place where the enclosed cooling tower vibrates. Vibration is one of the sources of sound, so adding a muffler sheet can relieve a lot of noise so that it will not produce that much noise. Of course, in order to improve the noise problem of the closed cooling tower, we can control it from the transmission medium, such as placing it in a control room with better sound insulation, so that it will not have a great impact on the environment. Setting up shelter forests is also a good way to improve the noise of closed cooling towers, after all, as long as the combination of the receiving source and the generating source is isolated, it is a good method.
The difference between the closed cooling tower and the open cooling tower 1. The cooling principle of the open cooling tower is that by spraying the circulating water on the glass fiber filler, through the contact between the water and the air, the heat exchange is achieved, Then there is a fan to drive the air circulation in the tower to bring out the hot air after heat exchange with the water, so as to achieve cooling.
With this cooling method, the initial investment is relatively small, but the operating cost is high (water consumption, power consumption).
1. The cooling principle of the closed cooling tower is, in simple terms, there are two cycles: an inner cycle and an outer cycle. There is no filler, and the main core part is a copper tube surface cooler.
①Internal circulation: It is connected with the target equipment to form a closed circulation system (the circulation medium is soft water). Cool the target equipment and take the heat from the target equipment to the cooling unit.
②External circulation: In the cooling tower, it cools the cooling tower itself. It is not in contact with the internal circulating water, but only conducts heat exchange and heat dissipation through the copper tube surface cooler in the cooling tower. In this cooling mode, the operation of the motor is set according to the water temperature through automatic control.
Two cycles, in the case of high ambient temperature in spring and summer, two cycles need to run at the same time. The ambient temperature in autumn and winter is not high, and in most cases, only one internal circulation is required.
4. Closed cooling tower, or closed cooling tower, also known as closed cooling tower, referred to as closed tower.
The closed cooling tower is derived from the evaporative cooler, but it is actually a heat exchanger that combines the performance of a water-cooled cooler and a conventional cooling tower, and is also a heat exchange between the water cooler and the air cooler. Therefore, some manufacturers call it "evaporative air cooler". There are many forms of this type of cooling equipment. The common feature is that water is sprayed outside the partition heat exchanger and forced ventilation. The heat is transferred from the cooled fluid in the partition heat exchanger to the spray outside the wall through the wall. The spray water is then transferred to the air through forced convection between the spray water and the air, and the heat transfer from the spray water to the air is mainly composed of the latent heat of the evaporation of the spray water and the sensible heat exchange between the spray water and the air. Since the fluid to be cooled flows in a closed loop between the dividing wall heat exchanger and the external process equipment, in order to distinguish it from the general cooling tower in which the fluid to be cooled is in direct contact with the air, it is called "closed tower", and the corresponding The general cooling tower is called "open tower".
