Heat recovery system of compressor oil system

Abstract

The invention provides a heat recovery system of a compressor oil system. The heat recovery system mainly comprises a water pump, a compressor, an oil-water heat exchanger, an oil pump, an oil outlet pipe, an oil inlet pipe, a cooling water inlet pipe, a cooling water outlet pipe, and a hot water box. The heat recovery system is operated in such a manner that lubricating oil located at an exit of the compressor enters the oil-water heat exchanger through the oil outlet pipe and the oil pump, the temperature of the lubricating oil is decreased after heat release, and the lubricating oil returns to the compressor through the oil inlet pipe; clean tap water enters the oil-water heat exchanger through the water pump and the cooling water inlet pipe, the temperature of the tap water reaches 60-70 DEG C after heat adsorption, and the tap water enters the hot water box through the cooling water outlet pipe; and hot water in the hot water box is allocated by heat users according to requirements of themselves.

Description

technical field [0001] The invention belongs to the technical field of industrial energy saving, and in particular relates to a heat recovery system for a compressor oil system. Background technique [0002] Compressor is a basic equipment widely used in industry. It converts the mechanical energy of the prime mover (usually an electric motor) into fluid pressure energy. It is the basic product of industrial modernization. At present, the compressors widely used in the world are mainly volume type and speed type, especially screw multistage compressors and centrifugal multistage compressors are the main products. [0003] Taking the air compressor as an example, the air passes through the intake filter to filter out the dust or impurities in the atmosphere, and then enters the compressor host through the intake control valve, and mixes with the sprayed cooling lubricating oil during the compression process. The mixed gas is discharged from the compression chamber into the o...

AI Technical Summary

Problems solved by technology

When the screw air compressor cools the high-temperature and high-pressure oil and gas through its own heat dissipation system, a large amount of heat energy is wasted for no reason; if the waste heat generated by the operation of the air compressor is not exchanged, it may cause the motor to High temperature and high exhaust temperature will not only affect the service life of the air compressor, but also affect the quality of compressed air; if the heat is directly discharged by the cooling system, it will not only waste energy, but also cause thermal pollution

[0004] In the past, the heat in the circulating cooling water was directly discharged to the cooling tower, which could not give full play to the role of waste heat, and this part of the heat actually came from the electric energy consumed by the air compressor. The water is evaporated, resulting in water loss, and the formed water mist combines with fine suspended particles in the air, which will cause adverse effects on the local environment. In some cases, in order to speed up the cooling process, it is necessary to start the fan on the top of the cooling tower, consuming large amount of power
