Air compression station waste heat recovery system based on water source heat pump unit

Abstract

The invention relates to the technical field of air compression station waste heat recovery, and discloses an air compression station waste heat recovery system based on a water source heat pump unit.The air compression station waste heat recovery system based on the water source heat pump unit comprises the water source heat pump unit, an air compression station cooling system and a water storage tank, wherein the water source heat pump unit is mainly composed of a compressor, an evaporator and a condenser, the air compression station cooling system is mainly composed of an air compressor, acirculating water pump, a cooling tank and a cooling tower, a water conveying pipeline with a circulation loop is connected between the air compressor, the cooling tower, the cooling tank and the circulating water pump, and a water conveying pipeline with a circulation loop is connected between the compressor, the condenser and the evaporator. According to an air compression station waste heat recovery system based on the water source heat pump unit, heat energy is extracted from an air compression station cold zone system through the water source heat pump unit, after pressurizing is carriedout through the compressor, high-temperature high-pressure steam is formed, the high-temperature high-pressure steam is exchanged with cold water on the condenser side, domestic hot water is prepared, low-grade energy can be converted into high-grade energy by relying on a small amount of electric energy input to drive the air compressor, and the efficiency of efficient utilization of waste heatof the air compression station cooling system is improved.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery of an air compressor station, in particular to a waste heat recovery system of an air compressor station based on a water source heat pump unit. Background technique [0002] The air compressor station is a kind of air source device, which uses compressed air as the power source of industrial production. The air compressor station will generate a lot of waste heat during operation. In order not to affect the normal operation of the air compressor station unit, the water level carrier is usually used to The heat is taken out, and it is discharged into the atmosphere in the mode of cooling water tower, and a part of electric energy needs to be input in the process. In this case, a lot of energy is wasted. Therefore, certain measures are usually taken to recover the waste heat and make use of it. In the field of domestic water such as shower hot water preparation, while reducing the conve...
