Compressor with multistage filtering device

Abstract

The invention relates to the technical field of compressors, in particular to a compressor with a multistage filtering device. The compressor with the multistage filtering device comprises a main shell and a conchoids turbine mechanism fixed in the main shell. A first chamber, a second chamber and a third chamber are longitudinally formed in the main shell, the turbine mechanism is installed in the first chamber, and an air inlet passage hole communicating with the inside of the first chamber is formed in the upper end of the left side wall of the main shell. According to the compressor with the multi-stage filtering device, the first, second and third chambers are formed in the main shell, and a detachable slow-flow filtering net plate and an elastic metal silencing block are arranged inthe second chamber, so that the filtering effect of the filtering device is greatly improved, and the assembling and disassembling are convenient; and meanwhile, the impact of high-pressure gas on theinner wall can be greatly reduced by utilizing an elastic slow-flow plate in the third chamber, the service life is prolonged, and the early-stage installation and later-stage maintenance costs are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor with a multi-stage filtering device. Background technique [0002] A compressor is a power device that uses an internal combustion engine or an electric motor to compress atmospheric pressure gas into high-pressure gas and has airflow energy. In the natural gas transmission and distribution system, the compressor is used to compress the natural gas, increase the pressure or delivery capacity of the natural gas, and often use the compressor to transport the compressed gas to replace the impurities in the pipeline when cleaning the pipeline, so as not to block the pipeline. Therefore, the compressor is often compared to the heart of the pipeline. The internal structure of the current compressor is closed, and the early assembly and post-cleaning maintenance are very troublesome, resulting in high cost of use.
