Combined oil mist purifying unit of air conditioner

Abstract

The invention discloses a combined oil mist purifying unit of an air conditioner. The combined oil mist purifying unit comprises an air return filtering part and a fresh air conveying part, wherein the oil return filtering part is used for performing suction filtering on air in a workshop and filtering oil mist particles and comprises an air return section, an oil mist filtering section, a peculiar smell purifying section, an air return fan section and an exhaust regulating section which communicate in sequence; the fresh air conveying part is used for feeding clean fresh air into the workshop and regulating the temperature of the air, and comprises a fresh air regulating section, an air filtering section, a temperature adjusting section, an air feeder section and an air feeding section which communicate in sequence; the exhaust regulating section and the fresh air regulating section communicate by an air mixing valve; and an exhaust valve and a fresh air valve are jointly arranged on a thermal recovery section. According to the combined oil mist purifying unit disclosed by the invention, by organically combining oil mist purification and the air conditioner, exhausting and thermal recovery can be realized; in addition, no cross contamination exists in the fresh air and the exhausted air; and the temperature and the air volume can be adjusted according to the technological requirements. The combined oil mist purifying unit has the functions of utilizing waste heat of the unit and purifying waste gases, and has the advantages of safety, reliability, reduction of pollution, convenience in technological operation and high degree of automation.

Description

technical field [0001] The invention relates to the air purification and air-conditioning technology of large-scale workshops such as automobiles and aviation machines, in particular to a combined air-conditioning oil mist purification unit. Background technique [0002] With the development of industry, large-span and large-space industrial plants have emerged, such as aircraft CNC machining centers, automobile engine CNC machining centers, etc. The span can generally reach 24m, the maximum can reach 50m, and the height can generally reach 15m. The use of local exhaust and centralized exhaust purification systems in such tall air-conditioned industrial plants has its limitations. [0003] In order to effectively lubricate, cool and clean during the machining process, the metalworking fluid has to go through the process of pump circulation, spraying, violent impact with high-speed rotating tools or workpieces, and high-temperature evaporation during use, which determines the...
