1. Schematic diagram of waste heat recovery for screw air compressor:

Introduction to the working principle of screw air compressor: The working principle of the air compressor is that a pair of parallel and meshing male and female rotors (or screws) rotate in the cylinder, causing periodic volume changes in the air between the rotor teeth. The air is then transported from the suction side to the output side along the rotor axis, thus realizing the entire process of suction, compression, and exhaust of the air compressor. The inlet and outlet of the air compressor are located at both ends of the housing, and the slots of the female rotor and the teeth of the male rotor are driven to rotate by the main motor.

By utilizing the principle of thermal energy conversion, the heat emitted by the air compressor is recovered and converted into water. After the water absorbs the heat, the water temperature will rise, causing the operating temperature of the air compressor unit to be low. This not only improves the efficiency of the air compressor operation and extends the service life of the air compressor lubricating oil, but also the recovered hot water can be used for employee hot water bathing, office and production workshop heating, boiler replenishment water, metal coating cleaning treatment, cleanroom constant temperature workshop and other places that require hot water, thereby reducing the long-term operating costs paid by enterprises for welfare and industrial hot water.

2. Introduction to air compressor waste heat single recovery unit:

• All internal components are made of stainless steel, which has strong corrosion and rust resistance, effectively protecting the internal components of the equipment and extending its service life.

• Touch screen+programmable controller, realizing visual fully automatic control, the waste heat unit runs completely automatically with the start and stop of the air compressor.

• The intelligent control system for waste heat recovery can monitor the operation of the unit, water tank temperature, water tank level, control the operation of the water pump, system water supply, etc., and can freely set corresponding parameters according to requirements.

• Independent of the air compressor unit, the operation of the air compressor has no impact and is convenient for later maintenance and upkeep.
