Abstract

The invention discloses a waste heat recycling system of an oil injection screw air compressor. The waste heat recycling system comprises an oil cooling system and a heat recycling system, wherein the oil cooling system comprises a cooling tower and a first plate type heat exchanger which is connected with the cooling tower through a pipeline, and the heat recycling system comprises a heat storage water tank and a second plate type heat exchanger which is connected with the heat storage water tank through a pipeline. The waste heat recycling system provided by the invention solves the problems of the existing waste heat recycling system of an air compressor, such as high pressure loss and high leakage possibility.

Description

technical field [0001] The invention belongs to the technical field of air compressors, and relates to a waste heat recovery system of an oil-injected screw air compressor. Background technique [0002] At present, compressed air is one of the most widely used power sources in the industrial field, and it can be applied in the textile industry, injection molding industry, electronics industry, mining industry and so on. Because of its many advantages such as safety, pollution-free, good adjustment performance, and convenient transportation, it is more and more widely used in modern industrial fields. But it takes a lot of energy to get high-quality compressed air. In most production enterprises, the energy consumption of compressed air accounts for 10% to 35% of the total electricity consumption. According to the thermodynamic principle of the compressed air production process, only about 15% of the electric energy consumed by the screw compressor is converted into the pot...
