A high-efficiency closed-circuit cooling tower capable of automatic descaling

Abstract

The invention discloses a high-efficiency closed cooling tower capable of carrying out automatic fouling removing. The high-efficiency closed cooling tower capable of carrying out automatic fouling removing structurally comprises a heat dissipation draught fan, a cooling tower body, an air filtering net, a spraying liquid connecting pipe and a supporting base. The closed cooling tower is combinedwith an air spraying fouling removing device through a heat exchanging pipe cleaning device. When fouling generated on the surface of a heat exchanging pipe body reaches a certain thickness, the heatexchanging pipe cleaning device can scrape the fouling in time, meanwhile, the air spraying fouling removing device carries out cleaning at the position of a U-shaped pipeline of the heat exchanging pipe body, it is guaranteed that the fouling is completely cleaned away, the situation that spraying liquid drops to the heat exchanging pipe body and then is evaporated, impurities are left, the fouling is formed after long-time accumulation, and consequently the heat exchanging capacity of the heat exchanging pipe is lower is avoided, and the working efficiency of a heat exchanger is improved.

Description

technical field [0001] The invention relates to the field of heat exchange equipment, in particular to a high-efficiency closed cooling tower capable of automatic descaling. Background technique [0002] With the rapid development of the manufacturing industry, my country has become a large industrial country, but in the process of power generation and industrial production, a large amount of waste heat needs to be discharged into the atmosphere. The cooling tower is discharged after cooling, but the current technical considerations are not perfect, and it has the following disadvantages: the waste heat generated by the thermal power plant can reach more than 200 degrees, so when the waste heat enters the heat exchange tube of the cooling tower, the spray liquid above After falling on the main body of the heat exchange tube, it will quickly vaporize and evaporate, and the impurities in the spray liquid will remain on the surface of the main body of the heat exchange tube.

[0002] With the rapid development of the manufacturing industry, my country has become a large industrial country, but in the process of power generation and industrial production, a large amount of waste heat needs to be discharged into the atmosphere. The cooling tower is discharged after cooling, but the current technical considerations are not perfect, and it has the following disadvantages: the waste heat generated by the thermal power plant can reach more than 200 degrees, so when the waste heat enters the heat exchange tube of the cooling tower, the spray liquid above After falling on the main body of the heat exchange tube, it will quickly vaporize and evaporate, and the impurities in the spray liquid will remain on the surface of the main body of the heat exchange tube. After long-term accumulation, a layer of dirt will be formed on the surface of the main body of the heat exchange tube. The heat exchange capacity of the main body of the tower heat exchange tube becomes worse, which reduces the treatment effect of the cooling tower
