Problems solved by technology

However, it is difficult to control the temperature of the hot water obtained by heating, so that the heat energy is wasted in the water use link, and the energy utilization efficiency is not high
[0003] When the air compressor is running, the electrical energy is converted into compression potential energy. When the object is compressed, heat will be generated due to molecular extrusion, and 70%-90% of the electrical energy consumed by the motor will be converted into heat energy, which will cause energy waste.

Abstract

The invention discloses an energy-saving system and method for heating based on air compressor waste heat recovery transformation. The energy-saving method for heating based on air compressor waste heat recovery transformation comprises the step of S1, carrying out the oil-water heat exchange on heat generated by the work of an air compressor through a primary heat exchanger of a heat exchange unit so as to obtain primary heat exchange water, and detecting the state of oil-water heat exchange in real time so as to form primary heat exchange data. The recovery energy-saving system and method for heating based on air compressor waste heat transformation have the advantages that an original cooling system of the air compressor is replaced with the heat exchanger unit, high-temperature air compressor oil heat energy is replaced with hot water for heating application such as production or domestic hot water, the heat generated by the air compressor is fully utilized, the energy-saving effect is achieved, in addition, the air compressor is protected to a certain extent, the water temperature, the oil temperature and the water tank liquid level are detected in real time, and the beneficial effects of temperature control, automatic water supplementing, circulating water conveying and returning and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of waste heat recovery of air compressors, and in particular relates to an energy-saving system for heating based on recovery of waste heat of air compressors and an energy-saving method for heating based on recovery of waste heat of air compressors. Background technique [0002] The air compressor is referred to as an air compressor for short. It compresses the volume of gas and increases the density of gas molecules per unit volume to increase the pressure of compressed air. It is a device that converts the mechanical energy of the motor into gas pressure. The high-temperature heat generated by the high-speed rotation of the screw of the air compressor also generates friction and heat. The high-temperature heat generated by the air compressor lubricating oil is mixed into oil / gas vapor and discharged from the body. The heat of this part of the high-temperature oil / air flow is equivalent to that of air 3 / 4 ...
