Jiangsu Yunuo Cooling Technology will introduce to you what insulation measures we take for closed cooling towers in environments that require cold.
As the industry's requirements for environmental protection become more and more obvious, many customers choose to use closed cooling towers as cooling equipment for products. Recently, we have seen that many customers are paying attention to the precautions of closed cooling tower equipment sites, which I will briefly describe. chat with us. The first thing to do is to understand the working principle of the sealing equipment. The closed cooling tower uses the principle of absorbing heat when water evaporates to cool the cooled liquid. Ventilation space, so the site of the equipment needs to be ventilated.
The equipment places of the closed cooling tower are generally divided into indoor and outdoor. If the equipment is placed indoors, it must be ensured that there are ventilation windows around it. If there is no ventilation, some ventilation equipment, such as air guides, needs to be added. ventilation. Under normal circumstances, it is recommended to place the equipment outdoors, in a space of at least 4 meters in length and width around the cooling tower, and do not place other components or equipment, otherwise it will not be conducive to the normal operation of the cooling tower. In summary, in addition to attaching importance to equipment skills, closed cooling towers cannot ignore the space conditions for placing equipment. This is the primary condition for the normal operation of the equipment. The heating plate of closed cooling towers is generally insulated with asbestos plates or asbestos cloths. Insulation, but the asbestos cloth is not easy to lay flat, and it also has a certain impact on the parallelism of the pressure plate. There are many varieties of asbestos board, and asbestos board should be used for the heat preservation of the heating board. The common specification is 1000x1000, 3-5mm thick, the board body is relatively regular, the parallelism is good, the compressibility is relatively uniform, and there is no peculiar smell at high temperature.
There are many thermal insulation methods for closed cooling towers, and asbestos cloth or glass, cloth can also be used to wrap aluminum hydroxide thermal insulation cotton for thermal insulation. At present, there is also a thermal insulation coating on the market that is currently used as an ideal material for thermal insulation. It is easy to spread and use under the condition of 150 ℃, and no scorch is found. At the same time, the material is very light and has strong plasticity, which can easily form a more beautiful surface. In the case of good thermal insulation, the closed cooling tower can work in a relatively stable environment and can better exert its performance. When choosing asbestos cloth or glass cloth, you must choose a regular manufacturer. The closed cooling tower makes the cooling circulating water not polluted by the external environment, but the price is high. The cooling circulating water of the open cooling tower is exposed to the outside for a long time, which is harmful to the water body, but the price is low; the closed cooling tower has a built-in stainless steel tank; open The cooling tower has no stainless steel tank and bottom. The cooling principle of the closed cooling tower is simply two links: an internal circulation and an external circulation. There is no filler, and the main part is the copper tube surface cooler.
The above is the relevant content introduced by Jiangsu Yunuo Cooling Technology.
The Company is specialized in R&D, production and sales of a variety of water cooling products, such as closed cooling tower, crossflow tower, countercurrent tower, refrigerator, evaporative condenser, etc. In addition, the Company provides consulting of other relevant spare and accessory parts as well as technologies.
