Problems solved by technology
Since the circulating cooling water is in direct contact with the air for a long time, the dust and other harmful substances contained in the air also enter the circulating cooling water. In addition to scaling in the cooler, it also causes alkaline intergranular corrosion on the cooling surface (especially the cooling surface adopts It is more serious when it is made of stainless steel), which will eventually lead to partial leakage of the heating surface of the cooler, which will pollute the lubricating oil and power oil, and the circulating cooling water will also be polluted by oil, resulting in the deterioration of the heat transfer of the whole system

Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing:
[0015] In the main cooling soft water closed cycle, it is composed of the condenser cooling water return pipeline 9 of the refrigeration system condenser 8, the oil station cooling water return pipeline 16, 17, and the cooling water return pipeline 18 of the coolers. The return water flows into the closed cycle soft water return main pipe 28, and after being cooled by the heat exchange tube 29 of the surface evaporative air cooler 27, the soft water outlet pipe 30 of the surface evaporative air cooler is connected to the soft water closed cycle After the water pump 31 boosts the pressure, it is sent to each cooler through the closed circulation soft water supply main pipe 32. Two groups of cooling heat exchangers are arranged in the freezing dehumidifier: freezing dehumidification cooling heat exchangers 7 and 20, and the freezing dehumidification cooling heat exchangers 7 ...

The invention relates to circulation and cooling system. It is formed by surface evaporation air cooler and refrigerating dehumidifier. The cooling medium can be soft water or desalt water. The condensed water from the refrigerating dehumidifier can be used as complementing new water finally complemented to surface evaporation air cooler outer circulation system through condensed water filter, condensed water pipeline, new water complementing pipeline, open ditch pool. The invention can remove fouling for each cooler, harm caused by corroding, reduce new water supplying quantity from outer. It can be used in large scale air turbine mechanism, air refrigerating dehumidifier, electric machinery etc, northern area, or southern moist heat area.
Description
technical field [0001] The invention belongs to the technical field of general heat exchange, and particularly relates to a soft water (or demineralized water) closed cycle evaporative cooling system, and the system is mainly used for closed cycle evaporative cooling of power rotating mechanical equipment and lubricating oil systems. Air freezing and dehumidification equipment is required. A closed loop cooling system for cooling soft water to ≤33°C, especially during high temperature periods in summer. Background technique [0002] At present, the cooling of the electric motor in the blast furnace blower station in the iron and steel plant or in the power station of other industries, the cooling of the lubricating oil station and the power oil station, and the cooling of the refrigeration compressor with refrigeration and dehumidification devices all adopt open industrial water circulation cooling. system, the evaporated water taken away by the open cooling tower fan is ab...
