The four mounting holes 8 arranged inside the extended outer disk 6 serve to facilitate the fixed installation of the filter element into the natural gas compressor.

[0036] Working principle: When in use, the filter element is fixed to the inside of the natural gas compressor through the mounting screws in the mounting holes 8. During the filtering process, the four vertical round rods 12 support the inner wall position of the activated carbon filter 2, thereby improving the overall structural strength of the filter element. The four vertical round rods 12 can perform slight buffering activities under the action of the reset spring 19, thereby achieving the purpose of elastic support for the filter element. The four vertical round rods 12 act as a skeleton structure, but do not have an air-guiding structure and will not suppress the gas, thereby not affecting the large-scale entry of gas. The skeleton structure formed by the vertical round rods 12 and the center plug column 14 is detachable. After replacing the new filter element, the skeleton structure can be reinstalled and continued to be used, saving costs. When replacing the filter element, you only need to twist the connecting sleeve 5 to separate and disassemble the connecting sleeve 5 from the top seat 3, and you only need to replace the filter screen part, so as to achieve the purpose of convenient disassembly and replacement, and complete the use of the filter element applied to the natural gas compressor unit.
