Natural gas pipeline filter

The utility model provides a natural gas pipeline filter which comprises a body provided with an inner shell, an outer shell and an insulating layer between the inner shell and the outer shell. The filter element is mounted in a cavity surrounded by the inner shell; the air inlet end and the air outlet end sequentially penetrate through the outer shell, the insulating layer and the inner shell to be communicated with the cavity; the plurality of electrodes penetrate through the outer shell and the insulating layer to be electrically connected with the inner shell and/or the filter element; and the controller is used for adjusting the voltage on the plurality of electrodes according to the temperature and/or the pressure in the cavity. According to the natural gas pipeline filter disclosed by the embodiment of the utility model, an electric field is formed or current is generated by applying different voltages, so that the adsorption capacity to dust and impurities is enhanced, the blockage problem is solved,
