High-temperature closed cooling tower with pre-cooling device

Abstract

The invention discloses a high-temperature closed-type cooling tower with a precooling device, which includes a cooling tower body, and a spray branch pipe is arranged in the cooling tower body, and the spray branch pipe is connected with a spray water pump through a first main pipe. A first group of serpentine coils and heat dissipation filler filter screens are provided below the spraying branch pipes. The bottom of the cooling tower body is a water tank, and a second group of serpentine coils is arranged in the water tank. The second group of serpentine coils is connected with the first group of serpentine coils through the second main pipe. In the present invention, by setting the first group of serpentine coils and the second group of serpentine coils, the second group of serpentine coils is located in the water storage tank for water immersion heat exchange, and the high-temperature closed cooling tower is well Realize pre-cooling, so that the high-temperature fluid enters the first set of serpentine coils after pre-cooling, thereby avoiding the overheated high-temperature water from causing the spray water to evaporate instantly on the surface of the first set of serpentine coils, and solving the problem of high-temperature fluid in the closed cooling tower. The problem that the outer surface of the coil is easy to scale and cannot be cooled.

Description

technical field [0001] The invention relates to a cooling tower, in particular to a high-temperature closed cooling tower with a precooling device. Background technique [0002] Generally, the temperature of the fluid cooled by the closed cooling tower is below 60°C. Because at this temperature the coils in the fluid cooler tend to keep the outside surface wet. When the temperature is too high, the spray water will quickly vaporize and evaporate after falling on the surface of the coil. The impurities in the water will remain on the outer surface of the coil and accumulate on the outer surface of the coil to form scale. Heat exchange energy, and eventually lose cooling capacity. Therefore, in the field of high-temperature fluid cooling, it is difficult to achieve a truly perfect application basis for closed cooling towers. [0003] At present, for the cooling of closed-type high-temperature fluid (above 60°C), pre-cooling must be carried out before entering the closed-typ...
