Air compressor waste heat recycling control system based on C8051 microprocessor

Abstract

The invention discloses an air compressor waste heat recycling control system based on a C8051 microprocessor. The air compressor waste heat recycling control system comprises a circulating water tank, a heat exchanger, a three-way proportional valve and temperature sensors. The circulating water tank is provided with a water outlet, a water inlet, a hot water output opening and water adding opening. The heat exchanger is provided with an oil return pipe and an oil outlet pipe which are connected to an air compressor and used for recycling the heat generated by the air compressor. The heat exchanger is further provided with a water outlet pipe and a water inlet pipe which are connected to the water inlet and the water outlet of the circulating water tank and used for heating the water in the circulating water tank. The three-way proportional valve is provided with two outlets and one inlet, wherein the inlet is connected to the water outlet of the circulating water tank through a circulating pump, one outlet is connected with the water inlet pipe inlet of the heat exchanger, and the other outlet is connected to the circulating water tank. The temperature sensors are respectively disposed in the oil outlet pipe, the oil return pipe, the water outlet pipe, the water inlet pipe and the circulating water tank. The air compressor waste heat recycling control system has the advantages that the C8051 microprocessor is used as a core processor for waste heat recycling control, integral control is achieved, a control module is integrated with a liquid crystal display module and a keyboard module, and the system is compact in structure, low in cost and good in reliability.

Description

technical field [0001] The invention relates to an air compressor waste heat recovery control system, more specifically, it relates to an air compressor waste heat recovery control system based on a C8051 microprocessor. Background technique [0002] Compressed air is one of the most widely used power sources in industry. Because of its many advantages such as safety, pollution-free, good adjustment performance, and convenient transportation, it is more and more widely used in modern industrial fields. At present, compressed air is generally produced by an air compressor (referred to as an air compressor). However, when the air compressor is running, a large amount of compression heat will be generated, and the energy consumed by the compression heat accounts for more than 85% of the operating power of the unit. Usually, this part of energy is released into the atmosphere through the air-cooled or water-cooled system of the unit, resulting in energy waste. The waste heat u...
