The height of the air inlet cylinder 2 is 3-10 cm higher than that of the waste particle recovery tank 1; and a check valve is arranged in the air inlet cylinder 2. In the design of the embodiment, the inlet cylinder 2 is higher than the waste particle recovery tank 1 to ensure that the particles captured in the tank are not overflowed into the inlet cylinder 2 when the tank is overfilled, so the overflow prevention design is adopted.
The rubber ring 8 is divided into an upper section and a lower section which are integrally formed, and the height value of the rubber ring is 1.5-3 cm; and the effective telescopic range is between 0.2 and 0.5 cm.

The air outlet end of the pressure reducing valve 142 is communicated with the back flushing pipe 15 at the corresponding position through a connecting pipe. In the design of the embodiment, the back washing structure is as follows: the pressure reducing valve 142 at the top of the compressed gas tank 14 releases compressed air, and the back flush built-in pipe 191 communicated with the back flush pipe 15 enters the tank body 19 of the purification equipment, and the design mainly considers that the back flush pipe 15 can be used as an access for maintenance or adding some powerful cleaning agents, so that the pressure reducing valve 142 and the back flush pipe 15 are connected by a detachable communicating pipe.
The electrode end of the electrostatic generation plate 11 for dust adsorption is connected with each of the tower tile plates 7. In the design of the embodiment, the solid particles are deposited by discharge on the surface of the anode after being charged negatively due to the combination of the solid particles and negative ions. The method for collecting the solid particles comprises the steps of ionizing gas by using an electrostatic field so as to enable the solid particles to be electrically adsorbed on an electrode. In a strong electric field, air molecules are ionized into positive ions and electrons, and the electrons encounter solid particles in the process of rushing to the positive electrode, so that the solid particles are negatively charged and adsorbed to the positive electrode to be collected.
The particle sizes of the filter screen grating of the tail cap 21, the multi-section filter element 24 and the filter element cylinder 17 for filtering particles are sequentially reduced; and the number of multi-stage cartridges 24 is typically between 3 and 7 stages. In the embodiment design, the core requires that the entire unit be backwashed, so that after the compressed gas is injected into the tank 19 of the purification unit, the backwashed solid particles can pass back through the respective filter element grids, and are blocked.
A use method for a solid waste particle capturing and recycling system comprises the following steps:
s1, starting the high-frequency vibrator 6: firstly, waste gas with solid waste particles enters the waste particle rotary box 3 through the air inlet cylinder 2, and at the moment, a one-way valve in the air inlet cylinder 2 is opened; the waste gas enters a large amount of tower tile groups and flows into the tower tile groups, at the moment, the high-frequency vibrator 6 in the tower top cover 5 is started, and high-frequency oscillation generated by the high-frequency vibrator 6 is directly transmitted to the vibration bearing plate 9 through the contact column 51; because the vibration bearing plate 9 is integrated with the tower tile plate through the four screw rods 10, and the rubber ring 8 is arranged between each two tower tile plates 7 as an interval, when the vibration bearing plate 9 generates high-frequency oscillation, the oscillation wave can be effectively transmitted to each tower tile plate 7; the starting and stopping time of the high-frequency vibrator 6 is intermittent, and the intermittent time is 3-5 min;
S2, primary catching process of solid waste particles: because a large amount of waste gas with solid waste particles billows and wanders in the inner cavity of the tower tile plate group; at this time, the static electricity generating plate 11 is started to make the solid waste particles adsorb on the surface of the tower tile plate 7 due to the action of static electricity; when the adsorbed particulate matter reaches a certain thickness; starting the high-frequency vibrator 6 in the step S1, and disconnecting the power supply of the static electricity generation plate 11, wherein the particulate matters adsorbed on the surface of the tower tile plate 7 all fall into the waste particle recovery tank 1;
s3, secondary catching process of solid waste particles: firstly, after the fan 23 is started, the fan can generate airflow in the tank 19 of the purification equipment, and the exhaust direction of the fan is that the air is sucked by the tail cap 21 and finally discharged by the top cap 20; because the primary particle capture in the exhaust gas is finished in S2, the exhaust gas purified once is sucked in by the tail cap 21, because the multi-section filter element 24 is loaded in the lower half section of the tank 19 of the purification equipment, the particles in the exhaust gas can be physically adsorbed in the multi-section filter element 24, the exhaust gas passing through the multi-section filter element 24 is finally discharged by the top cap 20, and the filter element cylinder 17 arranged on the top cap 20 is used for final filtration discharged into the atmosphere;
s4, and the process of back flushing of the equipment: because the multi-section filter element 24 belongs to physical adsorption dust removal, when waste particles are accumulated to a certain degree, the waste particles are blocked, and the purification effect is lost; at this time, the box door 26 of the air filter element box 25 is opened first, so that the gas in the waste particle convolution box 3 can be discharged, then the air compressor module 18 is started to charge compressed air into the compressed gas tank 14, and the gas outlet end of the compressed gas tank 14 after being charged is divided into two paths: the top of the compressed gas tank 14 is filled with compressed air into the back flush built-in pipe 191 through the pressure reducing valve 142 and the communicating pipe by the back flush pipe 15, at this time, the blade of the fan 23 in the tank body 19 of the purification equipment is also cleaned, and the core is as follows: the multi-stage cartridge 24 is subjected to the reverse high-pressure air flow, so that most of the exhaust gas particles are separated and blown into the waste particle cyclone box 3 by the tail cap 21, and the particulate matter trapping restarting S2 can be performed in the waste particle cyclone box 3;
In addition, because the air compressor modules 18 are annularly arranged on the base 12 of the purification device, in S4, the opening and closing of the pressure reducing valves 142 are designed to be in a periodic sequence, the periodic sequence of the opening and closing is that the valves are opened and closed sequentially in a clockwise or counterclockwise direction around the ring, and the time period of a single opening and closing is 0.2-0.8 second; the back flushing efficiency is improved by the way of filling compressed air into the back flushing built-in pipes 191 one by one;
the second path of the outlet end of the compressed gas tank 14 is designed on an exhaust groove 22 at the bottom position of the body of the air compressor module 18, the exhaust groove 22 is positioned in the equipment installation groove 4, and the exhaust of the high-pressure gas in the exhaust groove 22 can well clean the inner wall of the waste particle cyclone box 3; preventing refractory dust deposition; after the ash removal is finished, the particulate matters drop into the waste particle recovery tank 1 again to be collected; in addition, because the check valve is designed in the air inlet cylinder 2, when high-pressure gas is injected, exhaust gas particles of the high-pressure gas cannot be discharged from the air inlet cylinder 2 in a reverse direction, and only the air can be discharged through the air filter element box 25.
Through the steps, the solid waste particle capture and recovery are completed.
