Problems solved by technology

[0002] Air compressor is a commonly used equipment in industrial production. It has a wide range of uses. It is often used as a power source such as: pneumatic tools, item transfer, door and window opening and closing, material mixing, painting, etc. When the air compressor is running, it is driven by electricity. A lot of heat will be generated during operation, and the equipment needs to be cooled by means of fans and liquid circulation to ensure the normal operation of the equipment. The discharge of these heat is a serious waste of energy
In order to ensure production safety, large-scale industrial enterprises will use air compressors with various forms of heat dissipation. At the same time, they also need to filter and dehumidify the compressed air for production. Limited by the requirements of the production process, the operation of the air compressor is also intermittent. , discontinuous operation, when the pressure of the pressure tank reaches the pressure value, the equipment will stop, so the intermittent waste heat cannot be applied and supplied.

Abstract

The invention discloses a technical method for solving the difficult recovery of waste heat caused by the discontinuous operation of air compressors. The method comprises the waste heat recovery of the combined use of various air compressors. Meanwhile, the auxiliary dehumidification is conducted on compressed air, the waste heat recovery of an air-cooled air compressor, a liquid-cooled air compressor and a compressed air tank is achieved, the recovered waste heat is used for preparing hot water for production and life and heating water in winter, the possibility that the air compressors stoprunning is reduced, and it is guaranteed that a heat pump unit can work normally when the air compressors stop running.

Description

technical field [0001] The invention belongs to the field of waste heat recovery, and relates to waste heat regulation and recovery of air-cooled and liquid-cooled air compressors and compressed gas tanks. Background technique [0002] Air compressor is a commonly used equipment in industrial production. It has a wide range of uses. It is often used as a power source such as: pneumatic tools, item transfer, door and window opening and closing, material mixing, painting, etc. When the air compressor is running, it is driven by electricity. A large amount of heat will be generated during operation, and the equipment needs to be cooled by means of fans and liquid circulation to ensure the normal operation of the equipment. The discharge of these heats is a serious waste of energy. In order to ensure production safety, large-scale industrial enterprises will use air compressors with various forms of heat dissipation.
