The using method of the invention has the following working principle:
when the fumed silica small particles are recovered, the existing control system respectively controls the existing gas supply equipment and the exhaust pipe 10 to enable the gas supply equipment to start extracting gas to be recovered and filtered, the exhaust pipe 10 opens a valve, the gas containing the particles to be filtered and recovered is introduced into the air supply pipe 2 through the existing gas supply equipment, then the gas is enabled to respectively flow into gaps among the filter bag bodies 6 through the air supply pipe 2, the gas naturally flows, when the gas flows to the surfaces of the filter bag bodies 6, due to the textile characteristics of the filter cloth of the filter bag bodies 6, the small particles can be filtered when passing through the surfaces of the filter bag bodies 6, so that the small particles are separated from the gas to form the gas-solid separation effect, part of the small particles left by screening is attached to the outer surfaces of the filter bag bodies 6, part of the small particles is attached to the inner surfaces of the filter bag bodies 6, and the filtered gas passes through the exhaust pipe 10 and then is exhausted outwards.
After filtering for a period of time, at this time, a certain amount of fumed silica particles are accumulated on the surface of the filter bag body 6, the existing control system is used for controlling the existing air supply equipment to stop supplying air, meanwhile, the valve of the exhaust pipe 10 is closed, the control electromagnetic valve 13 opens the valve, and the air pump 4 and the pressure pump 12 are respectively electrified to enable the air pump 4 and the pressure pump 12 to start operating, the internal structures of the air pump 4 and the pressure pump 12 are the same as those of the existing air pump and pressure pump, the external pure and high-temperature air is extracted through the air pump 4, for the high temperature of the air, the air extracted by the air pump 4 can be heated through the heating equipment contained in the existing dust remover equipment, when the air pump 4 extracts the air into the air, the air is converted into strong airflow through the internal structure of the air pump, and the ventilating pipe 3 and the ventilating sieve plate 5 are used for ventilating, when the air is flushed into the inner cavity of the filter bag body 6, the air flow close to the inner side wall surface of the filter bag body 6 is guided by the shape track of the recovery circular track 7 on the inner side wall of the filter bag body 6, so that the air flow continuously follows the shape track of the recovery circular track 7 and continuously spirally flows in the gap between the tracks of the recovery circular track 7, the flowing air flow transversely blows and scrapes the fumed silica particles attached to the surface of the filter bag body 6, the particles are separated from the surface of the filter bag body 6, meanwhile, the particles are spirally upwards along with the air flow under the driving of the air flow force until the particles flow to the electromagnetic valve 13, the air flow completely flows into the inner cavity of the circulating pipe 11 through the electromagnetic valve 13, and when the air flow flows to the pressure pump 12, the air flow is pressurized and accelerated by pressurizing the pressure pump 12, so that the air flow can keep high speed, and is pressurized by the pressure pump 12, when the air current carrying particulate matters is pumped into the gap between each filter bag body 6, and is sprayed downwards, at the moment, because the air current has high temperature, and when the air current carries out rotational flow around the inner side wall of each filter bag body 6, the heat energy contained in the air current is conducted to the inner cavity of the recovery ring rail 7 through the surface of the recovery ring rail 7, so that the internal gas of the recovery ring rail 7 is heated and expanded, but the shape of the inner side wall protruding from the recovery ring rail 7 is fixed, and the outer side wall has elasticity, and further when the internal gas of the recovery ring rail 7 is heated and expanded, the outer side wall of the recovery ring rail 7 deforms and expands outwards, and a circle of external thread structure is formed gradually, when the pumped air current flows through the outer surface of the filter bag bodies 6, the air current is again influenced by the guiding of the external spiral shape track of the recovery ring rail 7, and flows downwards spirally around the outer surface of the filter bag bodies 6, and during the flowing process, the air current continuously blows and scrapes the particulate matters on the outer surface of the filter bag bodies 6, therefore, the internal and external surface of the filter bag bodies 6 are fully recovered by the spiral air current, and meanwhile, when the particulate matters are blown, the particulate matters cannot be easily diffused outwards, and further, and the particulate matters can be effectively prevented from flying.
When the air current flows to the bottom end of the filter bag body 6 in a spiral mode, the air current carries particles to flow to an ash bucket below through holes formed in the surface of the lower fixing plate 1, and therefore the particles are recycled, after the particles are recycled for a period of time, the air pump 4 and the pressure pump 12 are controlled to stop air supply and pressurization through an existing control system, meanwhile, the electromagnetic valve 13 is also made to close a valve, at the moment, high-temperature rotational flow stops, the temperature of the recycling circular rail 7 gradually drops as the gas is removed, the gas pressure of the gas in the inner cavity of the recycling circular rail 7 gradually drops, at the moment, the gas pressure borne by the spring 8 drops, and then the spring 8 starts to rebound.
After the spring 8 stops oscillating and the initial state is recovered, the existing gas supply equipment is controlled through the existing control system, and the exhaust pipe 10 is opened to start a new round of filtration and recovery of the fumed silica.
