Problems solved by technology

[0002] The centrifugal air compressor drives the gas to rotate at a high speed by the impeller, so that the gas generates centrifugal force. Due to the diffusion flow of the gas in the impeller, the flow rate and pressure of the gas after passing through the impeller are increased, and compressed air is continuously produced. Here During the process, a large amount of heat will be generated. The gas compression temperature is 120-180°C. Generally, it is cooled by the cooling water of the cooling tower, and the heat is discharged into the atmosphere through the cooling tower, causing energy waste and polluting the environment. The wasted heat is about To account for 80% of the power consumed by the motor

Abstract

The invention discloses a cascaded waste heat recovery device for a centrifugal air compressor. The cascaded waste heat recovery device comprises a primary heat medium circulating water part, a secondary heating circulating water part, a circulation cooling water part, a compressed air cooling part and an electric control part. Waste of energy sources is reduced, the heat production recovery rateof the centrifugal air compressor is high, and the centrifugal air compressor is protected better.

Description

technical field [0001] The invention belongs to the field of thermal energy utilization devices of centrifugal air compressors, and more specifically relates to a cascade waste heat recovery device of centrifugal air compressors. Background technique [0002] The centrifugal air compressor drives the gas to rotate at a high speed by the impeller, so that the gas generates centrifugal force. Due to the diffusion flow of the gas in the impeller, the flow rate and pressure of the gas after passing through the impeller are increased, and compressed air is continuously produced. Here During the process, a large amount of heat will be generated. The gas compression temperature is 120-180°C. Generally, it is cooled by the cooling water of the cooling tower, and the heat is discharged into the atmosphere through the cooling tower, causing energy waste and polluting the environment. The wasted heat is about To account for 80% of the power consumed by the motor. All this wasted heat ...
