If the cooling tower is left outside for a long time, it will be exposed to sand and dirt, especially the fan part. Such operation for a long time will reduce the cooling tower's heat dissipation capacity. How to clean the cooling tower? 1. First, drain the water from the cooling tower's water tray, and start cleaning from the water distributor on the tower, so that the water distributor can supply water normally and evenly. (For example, use tools to unblock the water hole gambling game).
What is a blast cooling tower
Cooling tower is a kind of thermal equipment that is widely used. Its function is to dissipate the heat of high-temperature cooling water into the atmosphere through heat and mass exchange, thereby reducing the temperature of the cooling water. Cooling towers can be divided into different types according to different classification methods. Among them, according to the ventilation method, there are natural ventilation cooling towers and mechanical ventilation cooling towers. Mechanical ventilation cooling...
What is the difference between evaporative condenser and closed cooling tower?
1. Closed cooling towers take water, while evaporative condensers take other refrigerants. The fundamental difference is that the evaporative condenser has a phase change in the cooled medium, but closed cooling towers do not. The so-called condensation is to condense the temperature of the gaseous state into a liquid state. These are called evaporative coolers. 2. The evaporative condenser must be connected to a closed system, which basically has a certain pressure. seal…
How to solve the problem of water floating in the cooling tower?
The standard drift rate of the cooling tower is generally 2%-5% of the circulating water volume. When the cooling tower is running, you can see that the cooling tower sprays a lot of small water droplets, like white mist, indicating that the cooling tower has serious water drift . Analysis of the floating water of the cooling tower: 1. The fan rotates at a high speed, resulting in strong air suction, which draws a large amount of small water droplets out of the cooling tower from the air cylinder; 2. After the hot and humid air leaves the cooling tower,
Cooling tower packing material distinction
As the core of the sewage cooling tower, the filler accounts for 20%-30% of the total cost of the sewage cooling tower, but it shoulders 60%-80% of the cooling capacity. The excellent filler properties can greatly improve the cooling efficiency of the cooling tower and play the role of the filler, which is an important aspect of improving the performance of the cooling tower. Sewage cooling towers are mostly used in industrial industries, and they are in a very harsh sewage environment.
The working principle of closed cooling tower:
1. The closed cooling tower is actually an evaporative cooling tower, a combination of a cooler and a wet cooling tower. It is a horizontal evaporative cooling tower. The process fluid flows inside the tube and the air flows outside the tube. Both Do not touch each other. The closed cooling tower is a modification and development of the traditional cooling tower. After the water in the reservoir at the bottom of the tower is pumped by the circulating pump, it is sent to the outside of the pipe and sprayed down evenly. It is not in contact with the process fluid hot water or refrigerant and the air outside the pipe, and becomes a closed cooling tower. The effect of heat and mass transfer is enhanced by spraying water.
2. The closed cooling tower is suitable for various cooling systems that require high circulating water quality. It has application prospects in electric power, chemical industry, steel, food and many industrial sectors. On the other hand, compared with air-cooled heat exchangers, evaporative cooling towers use the latent heat of evaporation of the water on the lower side of the tube to significantly enhance heat and mass transfer on the air side, which also has obvious advantages.
Closed stainless steel cooling tower, as a kind of cooling tower, adopts the method of placing the heat exchanger in the stainless steel cooling tower. Through the air circulating in the tower, the spray water and circulating heat are exchanged to ensure the cooling effect of the cooling tower. Because the equipment uses a closed internal circulation method, it can ensure that the quality of the water is not polluted by work, which not only protects the more efficient operation of the main equipment of the cooling tower, but also increases the service life of the cooling tower itself. Because the stainless steel cooling tower is equipped with an automatic temperature control device, when it senses that the outside temperature is low, it can automatically close the water spray system and stop running, which saves water use.
The price of closed stainless steel cooling tower is affected by the selection and material. Stainless steel cooling towers are made of aluminized zinc plate, FRP and stainless steel. The cooling coils are also divided into copper tubes, T2 copper tubes, stainless steel tubes and carbon steel tubes. The cooling water volume of the cooling tower ranges from 1T to several hundred tons. According to the market situation of cooling towers this year, the development of cooling towers is relatively stable. Therefore, the price of stainless steel cooling towers is mainly affected by raw materials, and the overall average price is stable.
The larger the design water volume of the closed stainless steel cooling tower, the more cooling coil water volume will be required. The raw materials used in the cooling coil are stainless steel pipes, copper pipes and carbon steel pipes. The price of carbon steel pipe is the lowest, and T2 copper is better. Therefore, the price of stainless steel cooling towers will vary greatly. The price of copper pipes of the same thickness can be twice as high as that of carbon steel pipes. The dense structure of the surface of the stainless steel tube can effectively reduce the formation of scale. The production cost control of closed stainless steel cooling towers can be divided into multiple grades in the production materials of the cooling towers.
When many companies buy stainless steel cooling towers, they will compare and compare multiple production plans. However, the price of stainless steel cooling towers that are almost the same sometimes varies a lot. To a certain extent, this will cause a certain cost increase due to the local raw materials and production labor. However, if the price difference of the stainless steel cooling tower is too great, then it is necessary to consider whether the production material of the enclosed cooling tower is a real material.
At the same time, this kind of stainless steel cooling tower can also save more manpower for the production company. It is like saying that anti-freezing work is required when the general cooling tower is not used, but the stainless steel cooling tower does not need to do this work. The reason is because the stainless steel cooling tower adopts a fully enclosed water circulation system, and the water surface has little contact with the air, and the heat preservation effect will be very good, so there is no need to do any antifreeze work. This will save the company more manpower.

The main raw materials and types of closed cooling towers:
1. For the motor, it is necessary to choose a completely enclosed product with a quality certificate to prevent circulating water from floating into the motor during the working process, causing the motor to burn.
2. The water collector, filler, the water collector, and the filler must be made of Formosa Plastic PVC material with heat insulation and antifreeze, so that the effect of the equipment will not be affected regardless of the hot summer or the severe cold winter.
3. Cooler. The cooler is the core part of the closed cooling tower. Generally, the wall thickness of φ22 copper tube is ≥0.6mm, because among the many metal elements, the corrosion resistance, heat transfer and cost performance of copper tube are all It is an ideal choice
4. Plate, cold zinc anti-corrosion plate of national standard, plate thickness ≥2mm. According to actual requirements, thicker or thicker galvanized panels can also be used, or stainless steel panels can be selected.
5. Circulating pump, the same principle as the motor selection, the circulating pump should also choose a fully enclosed water pump.
