Problems solved by technology

Therefore, there is currently no report on the recovery of low-temperature waste heat from cooling circulating water in air compressor stations in China.
[0003] On the other hand, the cooling circulating water of the existing domestic air compressor station needs to be cooled by cooling towers to realize the circulating cooling of the air compressor, which not only wastes the waste heat in

Abstract

The invention discloses a system and a method for recycling waste heat of cooling circulated water of an air compression station. The system comprises an upper computer, a distributed control system (DCS) control cabinet, a cooling circulated water pipeline of an air compressor, a water charging pipeline of a boiler deaerator, an absorption heat pump unit and a cooling tower pipeline. The method for recycling the waste heat comprises the following steps of: extracting the waste heat of the cooling circulated water of the air compressor by the absorption heat pump unit to heat the boiler deaerator for water charging; and delivering redundant waste heat to a cooling tower for cooling so as to ensure the normal operation of the air compressor. By the system and the method, the waste heat of the cooling circulated water of the air compressor can be completely or partially recycled according to heat supply demand to achieve the purposes of remarkably saving energy and water resources.

Description

technical field [0001] The invention belongs to the technical field of low-temperature waste heat recovery, and in particular relates to a waste heat recovery system and method for cooling circulating water of an air compressor station. Background technique [0002] Due to the low temperature of the cooling circulating water in the air compressor station, its temperature is generally equivalent to the outdoor temperature when it enters the air compressor, and the temperature rises by about 5-10°C when it exits the air compressor. Tube heat exchange method recovery. Although the technology of using absorption heat pumps to recover low-temperature waste heat is being gradually promoted in China, and there are reports about using absorption heat pumps to recover waste heat from cooling water in condensers of thermal power plants, there is no systematic application of waste heat recovery from cooling circulating water in air compressor stations. Therefore, there are currently n...
