Thermal recovery circulating system of air compressor

Abstract

The invention provides a heat recovery and circulating system of an air compressor. Typically, a heat-transferring device is arranged between the air compressor and a cooler. The system can recycle the heat energy produced by the air compressor effectively, and converts the heat into heat resources for other purposes, uses a pump to pressurize cooling water to make the cooling water to pass through the air compressor, the heat transferring device and the cooler respectively, uses a controller to monitor the temperature of the cooling water flowing through the air compressor and the cooler, and then outputs a control signal after calculation according to the preset condition so as to control the acceleration-deceleration or operation stop of the cooler so that the cooling water can flow back to the pump via the cooler after passing through the air compressor and the heat transferring device to form the heat recovery and circulating system. With control of the temperature of the cooling water at control positions, the heat recovery and circulating system can achieve the optimum recovery and heat dissipating efficiency.

Description

technical field [0001] The invention relates to a heat recovery cycle system, in particular to a heat recovery cycle system that can effectively recover heat energy discharged from an air compressor, improve energy use efficiency, and reduce environmental damage caused by carbon dioxide and heat discharge. Background technique [0002] Existing air compressors and related cooling devices, as shown in Figure 1, pump 3 to inject cooling water into the internal cooler 11 of the air compressor 1, after the cooling water absorbs the heat generated by the air compressor 1 during operation Turn into hot water, then flow into the cooling water tower 2 through the control valve 21, use the cooling water tower 2 to cool the hot water into cold water, and then return to the pump 3 to form a cycle; and the above-mentioned cooling water pipeline is in front of the air compressor 1 , the rear end is respectively provided with a temperature transmitter 12, a pressure transmitter 13, can mo...

Problems solved by technology

[0003] However, in the above-mentioned prior art, the cooling water tower 2 is used to remove the heat energy generated by the air compressor 1 through heat exchange. The cooling water tower 2 directly discharges the heat into the atmosphere without recycling it, which not only has an impact on the environment (greenhouse effect and environmental pollution); at the same time, in order to supply hot water (energy) to other equipment in the plant, it is necessary to install boilers, electric heaters and other related heating equipment to generate heat (water) to supply the plant equipment Heat source (water), which also results in huge equipment setup costs, fuel costs and electricity costs
