Small-sized air compressor for environmental protection construction and using method thereof

Abstract

The invention discloses a small-sized air compressor for environmental protection construction and a using method of the small-sized air compressor, belongs to the field of air compressors. Accordingto the small-sized air compressor for environmental protection construction, the aerodynamic principle is utilized, two pneumatic parts get close to each other under the action of air flow, so that the front section area and the rear section area are greatly changed suddenly, the noise reduction effect is improved, and the larger the air flow strength is, the larger the section area of a pneumaticdeformation shell is changed, and the better the noise reduction effect is; an annular cavity in the inner part of a pneumatic weakening part is used for weakening the air flow velocity, and two airinlets and one air outlet can enable the air flow to form convection, so that a certain noise reduction effect is achieved; a porous air flow disturbance ball is used for further weakening the air flow velocity, finally, the air flow is sprayed out through air flow dispersing pipelines with different inner diameters, and noise reduction is carried out again through sudden change of the cross section area, so that the noise reduction effect is further improved; and compared with the prior art, dynamic change of the cross section area is achieved, and the noise reduction effect through sudden change of the cross section area is enhanced.

Description

technical field [0001] The invention relates to the field of air compressors, and more specifically relates to a small air compressor for environmental protection construction and its usage method. Background technique [0002] An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane or rotary screw. Air compressor is a general-purpose mechanical product with a large quantity and a wide range. It is widely used in machinery, mining, chemical industry, construction and other departments. The noise level it produces is high and has a great impact. For various manufacturing departments, solving the noise problem of air compressors can further improve the quality of products. Solving the noise of air compressors can greatly help improve people's livelihood and environmental pollution. Air compressor noise pollution needs reasonable control. [0003] The main noise...

Problems solved by technology

[0004] The resistant muffler is composed of a tube and a chamber with a sudden change interface, but the internal structure of the existing resistant muffler is fixed, and the cross-sectional area of ​​the pipe cavity cannot be changed, which means that its ability to reduce noise is limited. Limited, if there is no good noise reduction during construction, the noise will be amplified several times in an open environment, which will inevitably affect the surrounding environment
