7. A method of using a natural gas impurity removal unit according to any one of claims 1 to 6, comprising the steps of:
step one, natural gas enters a heat exchange box (12) after passing through an air inlet pipe (11), then enters a filter box (13) after being filtered by a filter screen (39), and enters a gas transmission pipe (14) from the filter box (13), and then the natural gas flow rate is improved and enters a condensing tower (15);
secondly, cooling sources are led into the condensing coil (25) and the condensing pipe, natural gas entering the condensing tower (15) flows in the inner cavity of the condensing tower (15) through the guide of the spiral blades (24), and partial impurities in the natural gas are condensed in the inner cavity of the condensing tower (15) under the influence of low temperature;
step three, natural gas condensed in the condensing tower (15) is output into the impurity removing tower (17) under the action of the pump (16), and impurities in the natural gas are absorbed by the adsorption layer (27);
discharging the natural gas subjected to impurity removal from the exhaust pipe (19) to an air outlet pipe fitting (20), discharging the natural gas discharged from the air outlet pipe fitting (20) to a next processing point, and enabling the natural gas to exchange heat with the natural gas input into the heat exchange box (12) after passing through the exhaust pipe (19) so as to pre-cool the natural gas before being input into the condensing tower (15);
step five, starting a motor (30) to work so as to enable a driving disc (31) to rotate, enabling the driving disc (31) to drive a pull rod (32) to move, enabling a sliding column to slide back and forth in a sliding groove, accordingly pulling a driving rod (34) to slide back and forth in a rectangular hole, cleaning the outer wall of an exhaust pipe (19) in the lifting process by a cleaning plate (35), and cleaning a filter screen (39) by the cleaning plate (35) through a connecting rod (36) pulling a cleaning rod (37).
