Abstract

The invention discloses a gas drying apparatus removing heat by utilizing a compressor and a method. The apparatus comprises the compressor (1), an oil-gas separator (2), a lubricating-oil heat recovery exchanger (3), an oil filterer (4), a compressor exhaust heat exchanger (5), a heat source regenerator (6), a solution storage tank (7), a concentrated solution pump (8), a dehumidifier (9), a dilute solution tank (10) and a dilute solution pump (11), wherein the gas outlet of the compressor (1) is connected with the inlet of the oil-gas separator (2), and the gas outlet of the oil-gas separator (2) is connected with the gas inlet of the compressor exhaust heat exchanger (5). The advantages comprise that the gas drying apparatus is capable of effectively recovering waste heat generated when an inflator runs, and the waste heat is utilized for drying processing of compressor exhausted gas and other gas resources, so that the compressor exhausted gas and other gas resources can satisfy the technological requirements; and the technology not only helps to reduce the consumption cost of energy, but also helps to reduce environmental pollution.

Description

technical field [0001] The invention belongs to the technical scope of comprehensive and high-efficiency utilization of energy, and relates to a method and device for drying gas by utilizing exhaust heat of a compressor, and specifically relates to a recovery and utilization system of exhaust heat of a compressor. Background technique [0002] Compressed air is one of the most widely used power sources in industry. 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 obtaining high-quality compressed air requires a lot of energy. In most production enterprises, the energy consumption of air compressors accounts for 10%-35% of the total power consumption. When the compressor is running, the input electric energy is mainly converted into two energy forms: the potential energy of increasing air pressure and the heat energy generated by mechani...
