A screw air compressor cooling device

Abstract

The invention relates to a screw air compressor cooling device. An upper end of a screw air compressor is provided with a pipeline for gas delivery. The pipeline is connected with a first cooling device and a secondary cooling device. The first cooling device contains a cooling bucket. The lower end of one side of the cooling bucket is provided with a water inlet, and the upper end of the other side of the cooling bucket is provided with a water outlet. The pipeline passes through the cooling bucket and then enters the secondary cooling device. The secondary cooling device contains a sleeve which coats the pipeline. The lower end of the sleeve is equipped with several axial flow fans. Each axial flow fan is connected with fan blades which are inserted into the sleeve. Left and right sides inside the sleeve below the pipeline are both respectively provided with a track board, the upper part of which is equipped with a track. The screw air compressor cooling device has a simple structure and is low-cost. By a physical cooling method, influence of a chemical cooling method on gas composition is avoided, and extraction purity is raised. In addition, moisture content of cooled gas is low, and the gas is easy to dry.

Description

technical field [0001] The invention relates to an air compressor, in particular to a cooling device for high-temperature gas compressed by a screw air compressor. Background technique [0002] There are many types of air compressors, which can be divided into positive displacement compressors, reciprocating compressors, and centrifugal compressors according to their working principles. Now commonly used air compressors include piston air compressors and screw air compressors. This kind of air compressor is widely used. It will generate high temperature during operation. The temperature of the compressed gas will reach about 80°C. The compressed gas needs to be dried, but due to the high temperature, it is difficult to remove the moisture. Aggravated dry components, the current way to cool down the gas is generally to cool down the gas through an air compressor connected to a cold compressor or a cooler, but the gas passing through the cooler contains a large amount of impur...

Aggravated dry components, the current way to cool down the gas is generally to cool down the gas through an air compressor connected to a cold compressor or a cooler, but the gas passing through the cooler contains a large amount of impurities, and the magnesium and calcium in the condensed water Ions are easy to react with metal pipes and affect the quality of the gas
