Waste heat recovery device for air compressor

Abstract

The invention belongs to the field of air compressor auxiliary equipment, and particularly relates to a waste heat recovery device for an air compressor. The waste heat recovery device for the air compressor comprises a mounting base and an air compressor body. A buffer assembly is arranged in the mounting base, the upper end of the air compressor body communicates with a main steam outlet pipe, and the upper end of the main steam outlet pipe communicates with a suction fan through cooperation of a connecting assembly and an air suction pipe. One end of the suction fan communicates with a temporary storage box, and an air outlet assembly is installed in the temporary storage box. One end of the temporary storage box communicates with a waste heat recovery assembly through a secondary steamoutlet pipe. The waste heat recovery device for the air compressor has the following advantages that firstly, the buffer assembly is arranged to clamp and fix the air compressor body, and meanwhile the buffer damping effect is achieved; and secondly, a first flange and a second flange which are connected together through an anti-expansion gasket arranged on the connecting assembly are not prone to looseness even after thermal expansion and cold contraction occurs, the sealing performance of the first flange and the second flange which are assembled together is guaranteed through a sealing plate, leakage is not easy to happen, and heat loss is reduced.

Description

technical field [0001] The invention relates to the field of air compressor auxiliary equipment, in particular to an air compressor waste heat recovery device. Background technique [0002] Manufacturers who use air compressors generally do not recycle the waste heat generated during the working process of the air compressor, and this part of the waste heat is emptied and wasted in vain, resulting in a waste of energy. It is calculated that a 120Kw air compressor can dissipate 302MJ of heat in one hour, which is equivalent to the heat generated by burning 17.7Kg of coal. Therefore, how to recover and use these exhausted heat energy is a very meaningful work. For this reason, the patent authorization announcement number is that a kind of multifunctional air compressor waste heat recovery device is provided in the patent application document of CN207315601U. [0003] The multi-functional air compressor waste heat recovery device is conducive to improving the waste heat utili...

AI Technical Summary

Problems solved by technology

[0004] But above-mentioned multifunctional air compressor waste heat recovery device also has certain defect, for example air compressor can produce severe vibration feeling to base when running, and along with long-term use, the ground of base lower end can be sunken; In addition, its Although the set clamping block device can facilitate the quick disassembly of the air outlet pipe and the air delivery pipe, it does not consider the effect of thermal expansion and contraction of the metal material, and it is easy to cause a gap inside the clamping block, which can not only make the inside of the clamping block device loose, In addition, part of the heat is lost in vain when the high-temperature steam passes through the clamping block device.
