Environment-friendly and energy-saving closed evaporative condenser

Abstract

The invention relates to an environment-friendly and energy-saving closed evaporative condenser which comprises a box, an air inlet channel, a fan, a water collection trough, a water pump, a ball cock, a spraying water distributor, a straight cooling pipe, a water collecting plate, a hot air outlet, a water inlet and a water outlet. The air inlet channel is arranged at the bottom of the box, the water collection trough is arranged on one side of the air inlet channel, the water pump is connected to the water collection trough, the other end of the water pump is connected with the spraying water distributor at the top, the water collecting plate is arranged on the upper portion of the spraying water distributor, the straight cooling pipe is arranged on the lower portion of the spraying water distributor, and the water inlet and the water outlet are arranged on the pipe plate portions of the straight cooling pipe. According to the environment-friendly and energy-saving closed evaporativecondenser, the straight pipe connecting and conveying manner is adopted, the continuous flowing distance of liquid is reduced, and the problem that pipelines are partially prone to being scaled and being blocked is avoided; an oval pipe is adopted as a ventilation pipeline, dry points are not prone to being formed when wind and water are reverse, and the heat exchange effect of the condenser is greatly improved; and in addition, no filler is additionally arranged in the evaporative condenser, a large amount of space is saved, the size is greatly reduced, and the limitation of spraying water temperature is avoided.

Description

technical field [0001] The invention relates to an evaporative condenser, in particular to an environmentally friendly, energy-saving closed evaporative condenser used for closed cycle cooling of water and other media in the fields of iron and steel, petrochemicals, etc., and belongs to the field of media cooling. Background technique [0002] FRP open spray towers or various plate and tube heat exchangers are usually used for circulating cooling of water and other media. Among them, the glass fiber reinforced plastic open spray tower has a better cooling effect, but the medium is easily polluted; the heat exchange effect of the plate and tube heat exchangers is limited when used, and the traditional closed evaporative condenser has a good heat exchange effect, but due to its The long-pipeline delivery method of serpentine coils is adopted, so that the evaporative refrigerant is transported far away, and the serpentine tube has many detours, and the pipeline is thin and easy...

Problems solved by technology

Among them, the glass fiber reinforced plastic open spray tower has a better cooling effect, but the medium is easily polluted; the heat exchange effect of the plate and tube heat exchangers is limited when used, and the traditional closed evaporative condenser has a good heat exchange effect, but due to its The long-pipeline delivery method of serpentine coils is adopted, so that the evaporative refrigerant is transported far away, and the serpentine tube has many detours, and the pipeline is thin and easy to foul and cause blockage. In winter, the water is not easy to drain, and it is easy to freeze, which affects the replacement. thermal effect, and it is difficult to repair the length of the pipeline; at the same time, the traditional closed evaporative condenser adopts countercurrent ventilation for ventilation, and the replacement tube adopts round tube, which is easy to form dry spots, which is extremely unfavorable to the heat exchange effect; and the old-fashioned condensing Filling needs to be added to the condenser, which takes up a lot of space and makes the condenser bulky, and the filling limits the temperature of the spray water, generally less than 65 degrees, which affects the heat transfer effect
