The utility model discloses the theory of operation does:

the medium enters the cyclone separation zone in the equipment through the inlet, after the gas containing impurities enters the cyclone along the tangential direction, the airflow is strongly rotated under the diversion action of the cyclone, the airflow spirally enters the cyclone cylinder downwards along the cylinder, the solid particles with high density are thrown to the wall of the cyclone cylinder under the action of centrifugal force, and fall down along the wall of the cylinder to flow out of the cyclone cylinder to the bottom of the equipment under the action of gravity, and are discharged from a sewage outlet at the bottom of the equipment. The rotating airflow is contracted in the cyclone cylinder body to flow to the center, flows upwards through the cyclone exhaust pipe and flows into the separation cavity with the filter element through the cavity A. Under the action of certain pressure, the larger solid particles generally move linearly, the smaller particles can move freely, the filter element adopts a screening, blocking and blocking mode to capture the particles, the particles larger than or equal to 10 mu m and free liquid drops can not enter the filter element and are left outside, and the particles are gathered together and discharged to the bottom of the container. Some particles remain outside the filter element and can be broken down to the bottom of the vessel by the pulsing of the media flow during operation. The polyester fiber filter element belongs to deep filtration, dust and liquid drops with smaller particle sizes continuously collide with polyester fibers when passing through a bent channel of a filter layer, the kinetic energy is gradually reduced, when the kinetic energy is reduced to a certain value, particles with the particle size larger than or equal to 1 mu m are attached to the filter layer, and the particle size of solid particles retained in the polyester fibers is reduced along with the depth of the filter layer. The natural gas filtered by the filter element flows into the cavity B and then flows out through the medium outlet, and the process of filtering and separating is completed.
