Waste heat recovery system with air-cooled air compressor and dual heat exchangers

Abstract

The invention relates to a waste heat recovery system with an air-cooled air compressor and dual heat exchanger, which comprises the air-cooled air compressor, two air-water heat exchangers, an insulated water tank, a heating device, a heat exchanger, a water separator, a water collector, a controller and a temperature sensor. The two sides of the air-cooled air compressor are respectively provided with one air-water heat exchanger, the air-cooled air compressor is connected with the heat exchanger through a pipeline, the heat exchanger is arranged in the insulated water tank, the insulated water tank is connected with the heating device and a circulating water pump, and the water separator, the water collector, the controller and the temperature sensor are arranged on the connecting pipeline between the air-water heat exchanger and the heat exchanger. Heat discharged by the air compressor and heat of outdoor fresh air can be recycled by dual heat exchangers, the power consumption and operating cost for hot water supply via a fuel-fired, gas-fired or electric boiler can be reduced, the temperature of the outdoor fresh air can be reduced, the cooling effects of the air compressor can be improved, high-efficiency operation of the air compressor equipment can be ensured, and the system has the advantages of high heat recovery efficiency and large energy-saving potential and also has considerable economic benefits and extensive value of promotion and application.

Description

technical field [0001] The invention relates to the field of waste heat recovery and utilization of air compressors, in particular to an air-cooled air compressor double heat exchanger waste heat recovery system. Background technique [0002] At present, air compressors are widely used in my country, among which a large number of electronic and light industrial air compressors adopt air-cooled structure or water-cooled heat dissipation method, and the heat dissipation method of air-cooled structure accounts for more than 50% of the market share. The heat dissipation method of the air-cooled structure means that the heat generated by the air compressor is discharged to the atmosphere through the fan, and this heat dissipation method discharges the heat generated by the air compressor to the atmosphere in vain. However, the heat-requiring systems of the factory, such as pure water heating, domestic hot water, process hot water and air-conditioning box heating, consume a large ...
