[0002] In order to improve gas efficiency, a series of compressor stations need to be built along the natural gas pipeline to improve the gas pressure of the pipeline. The natural gas enters the inlet channel of the compressor from the inlet of the compressor. The compressor uses a motor-driven fan to compress the natural gas. Under normal circumstances, the natural gas needs to be compressed by multiple stages. The natural gas compressed by multiple stages enters the natural gas pipeline from the outlet of the compressor to realize natural gas transportation. During transportation, a filter structure needs to be installed in the pipeline to filter impurities. Thus, a natural gas compressor filter device is provided

By shaking, the impurities blocked in the first filter hole are shaken off, further avoiding blockage on the filter plate and affecting the filtering effect. However, in the above, only the physical interception of the first and second filter holes lacks multi-stage filtration (such as coarse filtration + fine filtration), and the treatment effect on small particles (such as <10 μm) is limited, which further leads to low filtering quality.

[0007] Preferably, the natural gas compressor filter structure includes a cylinder. Threads are machined on the right side of the outer wall of the cylinder. The left end of the inner wall of the cylinder is fixedly connected with a first filter screen through bolts.
