Huarui brand closed cooling tower is to place the heat exchanger (such as copper coil) in the tower, and exchange the heat energy of the circulating water in the coil with the circulating air and spray water outside the tube to achieve the purpose of cooling down. . In this way, we can ensure that the industrial fluid in the coil will not come into contact with the air and cause pollution and reduce fouling, thereby ensuring the reliable and efficient operation of the equipment throughout the year. With the closed coil pipeline, the fluid loss inside It can be minimized.
During the working process of the closed tower, the industrial fluid (soft water, oil or other) is driven by the main circulating pump to circulate between the closed tower heat exchanger and the equipment to be cooled, and the spray water is evenly sprayed on the heat exchanger. A uniform water film is formed on the outer surface of the heat exchanger. The cold air enters the tower from the air inlet below the tower body and flows through the surface of the heat exchanger counter-currently with the spray water. There are two heat exchange methods in this process, namely cold air The heat transfer with the cooling medium and the heat exchange of the spray water evaporation and absorption heat, the saturated hot humid air after absorbing the heat is discharged to the atmosphere by the fan, and the rest of the spray water flows into the water tank in the lower part of the tower, and is transported to the spray by the water pump. Compared with the traditional open cooling tower, the shower system can reduce the environmental impact and save more cooling water resources. The integration of the tower body and the heat exchanger also greatly reduces the land occupation and eliminates some pipeline layouts. And the complicated process of system layout.
The closed tower is suitable for induction heating and metal melting equipment; cooling of large motors, diesel engines, rectifier equipment, electric welding equipment, hydraulic stations and continuous casting equipment, etc., cooling of various reactors and condensers in the chemical industry; cooling of circulating water for various reactors and condensers; metal die-casting molds, Cooling of large molds such as injection molds; cooling of industrial solutions, such as quenching liquid, electroplating liquid, etc.
The cooling tower can be used alone or in combination with water-cooled screw chillers and water-cooled scrollsChillerAnd other industrial refrigeration equipment are used in conjunction to form an industrial cooling water circulation system to meet the production and operation requirements of various industries.
