High-speed centrifugal air compressor capable of pressurizing air inlet

Abstract

The invention belongs to the technical field of air compressors, and discloses a high-speed centrifugal air compressor capable of pressurizing an air inlet. The high-speed centrifugal air compressor comprises a compressor body, the air inlet of the compressor body is fixedly connected with an air inlet fan, and a transmission main shaft of the compressor body penetrates out of the air inlet of the compressor body and is in transmission connection with an air supply blade in the air inlet fan; and an air inlet of the air inlet fan fixedly communicates with a backflow device, and the air inlet end of the backflow device fixedly communicates with a spiral air inlet pipe. Water mist wraps dust in airflow, and when the water mist spirally flows downwards along with the spiral air inlet pipe, the water mist is finally thrown to the inner wall of the spiral air inlet pipe due to the centrifugal trend in spiral movement due to high mass, and the water mist with the dust adheres to the inner wall of the spiral air inlet pipe; and as more water mist particles are accumulated on the inner wall of the spiral air inlet pipe, water flow is finally formed and flows away, the purposes of dust removal and air-liquid separation are achieved, the air flow cannot be reduced, and the air pressure is maintained.

Description

technical field [0001] The invention belongs to the technical field of air compressors, in particular to a high-speed centrifugal air compressor capable of pressurizing an air inlet. Background technique [0002] Air compressor refers to air compressor. Air compressor is a kind of equipment that can be used to compress gas. It is mainly divided into reciprocating piston type, centrifugal type and screw type. It has a very wide application space in industry and is also One of the indispensable equipment for modern industrial construction. [0003] The air compressor has relatively high requirements for the air quality of the air inlet. If the air flow carries a large amount of dust pollutants into the compressor, it will cause damage to the compressor itself. Therefore, before the external air enters the compressor, a special The filter device filters the gas. The existing common filtering method is to use the filter to filter, but the disadvantage of this filtering method i...

[0003] The air compressor has relatively high requirements for the air quality of the air inlet. If the air flow carries a large amount of dust pollutants into the compressor, it will cause damage to the compressor itself. Therefore, before the external air enters the compressor, a special The filter device filters the gas. The existing common filtering method is to use the filter to filter, but the disadvantage of this filtering method is that the air permeability of the equipment is reduced due to the existence of the filter, resulting in a decrease in the air flow and wind pressure. Decreased air inlet efficiency
