Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to an energy recovery device for air compressors. Background Technology

[0002] An air compressor is a device used to compress gas. Similar in construction to a water pump, most air compressors are reciprocating piston, rotary vane, or rotary screw types. Centrifugal compressors are used extensively and are the main component of air supply systems. They convert the mechanical energy of a prime mover into gas pressure energy, generating compressed air. During long-term continuous operation, over 85% of the input power of an air compressor system is converted into heat. This heat is discharged with untreated compressor oil / vapor. Of this heat discharged to the outside, 85% can be utilized, equivalent to over 80% of the air compressor shaft power.

[0003] A search of existing published patents (CN202322928774.8) reveals a patent titled "An Energy Recovery Device for an Air Compressor." The device includes an air compressor body, a motor on one side of the compressor body, an air storage tank below the compressor body, a tank cover at one end of the tank, a threaded mounting head on the inner edge of the tank cover, a spiral heat recovery pipe inside the tank cover, a fixing rod at the center of the spiral heat recovery pipe, a positioning support at one end of the fixing rod, and a hanging lug on the top of the tank cover. This invention utilizes a spiral heat recovery pipe inside the air storage tank to store a certain capacity of cold water. When heat is generated internally, the spiral heat recovery pipe absorbs the heat, heating the cold water and converting it into hot water, thus improving energy utilization and enabling the air compressor to perform energy recovery.

[0004] However, the contact area between the recovery pipe and the air inside the gas storage tank is small, resulting in low heat recovery efficiency and room for improvement. Utility Model Content

[0016] Beneficial effects

[0017] This utility model provides an energy recovery device for an air compressor, which has at least the following advantages compared with the prior art:
