Cooling system

Abstract

The invention discloses a cooling system. The cooling system comprises a first circulating unit and a second circulating unit. The first circulating unit is provided with a cooling tower, and a firstbranch and a second branch which are connected in parallel with each other; the first branch is connected with a first heat exchanger in series, and the second branch is connected with a second heat exchanger in series; the two ends of the cooling tower are connected with the two ends of the first branch respectively, so that the cooling tower can form a first circulating loop with the first branch and / or the second branch respectively; the second circulating unit is provided with a cooling unit, a third branch and a fourth branch, the third branch and the fourth branch are connected in parallel, and the first heat exchanger is further connected to the third branch in series to achieve heat exchange between the first branch and the third branch; the second heat exchanger is further connected to the fourth branch in series so as to achieve heat exchange between the second branch and the fourth branch; and the two ends of the cooling unit are connected with the two ends of the third branch so that the cooling unit can form a second circulating loop with the third branch and / or the fourth branch. A cooler can be prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of cooling of production equipment in a cigarette factory, in particular to a cooling system used in a cigarette factory. Background technique [0002] Cigarette industry enterprises are equipped with air compressors, cold dryers, etc. The compressor in the air compressor generates compressed air, and the lubricating oil of the compressor is equipped with a cooler to use cooling water to reduce the oil temperature. The compressed air generated is high in temperature and requires The cooler cools down, especially some air compressors have two stages of compression, and the compressed air generated by each stage of compression requires a cooler to cool down. Therefore, there may be three independent coolers inside an air compressor. After the compressed air comes out of the compressor, because the compressed air contains water vapor, the production needs to use dry compressed air. Therefore, after the compress...

AI Technical Summary

Problems solved by technology

Because the cooling tower uses the cooling water to fall, the fan blows to cool down, and the cooling water contacts the air in the cooling tower. Dust and impurities in the air can easily enter the cooling water. The cooling water is dirty, and the cooler in the equipment is easily contaminated by impurities. Blockage or impurities attached to the inside of the cooler will affect the cooling effect and service life, and the cooler needs to be removed frequently for cleaning or replacement

Since enterprises generally install multiple air compressors and cold dryers, there are a large number of coolers, and the coolers in the equipment are relatively precise and installed inside the equipment. It is very troublesome to dismantle, clean, and install each time, consuming a lot of manpower and material resources. even affect production
