Abstract

The invention relates to a technique capable of improving the operating efficiency of an air compressor, and aims at providing a device and a method for improving the operating efficiency of the air compressor by utilizing air pressure waste heat. The device comprises the air compressor, wherein the air compressor is provided with three stages of compressors, an air cooler introduces air, and three stages of coolers output compressed air; the air cooler and an absorption type refrigeration unit are connected by pipelines to form a frozen water circulation loop; the absorption type refrigeration unit is connected with a heat exchanger through a pipeline, the heat exchanger is respectively connected with the three coolers by pipelines, and the three coolers are respectively connected with the absorption type refrigeration unit by pipelines to form a hot water circulation loop; the heat exchanger is connected with a water cooling tower by a pipeline to form a cold water circulation loop. Compared with the prior art, the device and the method for improving the operating efficiency of the air compressor by utilizing the air pressure waste heat, which are disclosed by the invention, have the advantages that the waste heat of the air compressor is effectively recycled and is used back in the air compression system, and the air in an inlet of the air compressor is cooled down and dehumidified, so that the quality and the efficiency of air generation of the air compressor are effectively improved; meanwhile, the operation cost and the maintenance cost of an air compressor set are reduced, and the purpose of saving energy and reducing consumption is realized.

Description

technical field [0001] The invention relates to a technology for improving the operating efficiency of an air compressor, in particular to an energy-saving technology for improving the operating efficiency of the air compressor by using waste heat, which is specially used for multi-stage centrifugal air compressors. Background technique [0002] Compressed air is one of the most widely used power sources in industry. Due to 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 needs to consume a lot of energy to obtain high-quality compressed air. In most production enterprises, the energy consumption of compressed air accounts for 10% to 35% of the total electricity consumption. [0003] Due to the low compression efficiency of air compression equipment, the pressure potential energy formed after air compression only accounts for about 20% of the in...
