After the filter tank 1 is placed in a specified position, the positioning frame 5 is used to form a support with the ground to achieve that the filter tank 1 is always perpendicular to the ground, and then the water tank 8 is placed to the outside of the positioning frame 5. The flow tube 7 connects the water tank 8 and the collection tank 4, and the stabilizing rod 6 supports the inside of the positioning frame 5, improves the stability of the positioning frame 5, and greatly improves the weighing capacity of the positioning frame 5. By distributing the reinforcing strips 3 on the outside of the filter tank 1, it is prevented that the external force directly contacts the filter tank 1 and causes damage. Then the flue gas of the boiler is connected to the air inlet to realize the orderly discharge of the flue gas into the inside of the filter tank 1, and the water tank 8 is started to realize that the water inside the water tank 8 is directly poured into the inside of the filter tank 1. Since the flue gas is in a high temperature state, it evaporates after contacting with water, and then the light particles in the flue gas extend upward, and the fixed particles in the flue gas increase their mass due to the wetting effect of water, and then they are more likely to settle under the action of gravity. Then the rising fine particles are filtered by the purification frame 13, and the purified gas is discharged through the outlet pipe 2. When the flue gas is treated for a long time, the internal through holes of the purification frame 13 are blocked, affecting the treatment effect.

At the same time, the second limiting ring 18 will move with the stop rod 16, slide inside the first limiting ring 17, and squeeze the first spring 19, so that the first spring 19 is compressed.

The second spring 20 inside the fixed column 10 supports the receiving bar 22 to ensure that the receiving bar 22 is always vertical inside the vertical groove 14. After the stop rod 16 is pulled, its inclined portion will be directly below the receiving bar 22, and then the compression of the receiving bar 22 will be released, and then the telescopic energy storage of the second spring 20 will be released, and the sleeve 21 will synchronously descend and squeeze one end of the extrusion rod 12, and then the extrusion rod 12 will expand from a parallel state to an inclined state inside the through groove 11.

[0021] In this embodiment, a slot 23 is provided at the bottom of the purification frame 13 at a position corresponding to the fixed column 10, and a receiving block 24 is fixedly connected to the inner side wall of the slot 23 at a position corresponding to the extrusion rod 12.

A knob 27 is rotatably connected to the top of the sleeve 26, and an extension shaft is fixedly connected to the bottom of the knob 27, and a linkage disk 28 is fixedly connected to the bottom of the extension shaft. After the extrusion rod 12 is unfolded, the pressure on the receiving block 24 will be released, and then the purification frame 13 will be lifted outward, and then the slot 23 will be separated from the outside of the fixed column 10, and the disassembly of the purification frame 13 will be quickly completed. At the same time, the knob 27 is rotated, the extension shaft rotates synchronously with the knob 27, and then the linkage disk 28 rotates synchronously with the knob 27.

[0023] In this embodiment, a rod 34 is fixedly connected to the side of the cylinder 30 away from the hypotenuse 32, and the rod 34 extends to the outside of the sleeve 26. A stop ring is fixedly connected to the outside of the rod 34, and a third spring 35 is sleeved on the outside of the stop ring and located on the outside of the rod 34. After the block 29 enters the interior of the V-groove 31, the cylinder 30 slides inside the sleeve 26 under the expansion and contraction energy storage of the third spring 35, and approaches the linkage disk 28, and then generates a pulling force on the rod 34, so that the rod 34 is retracted from the inside of the circular hole 36 into the inside of the sleeve 26, and then the connection between the cover plate 25 and the purification frame 13 is released.

[0024] In this embodiment, a circular hole 36 is provided at a position corresponding to the insertion rod 34 at the top of the purification frame 13, and a rubber block 37 is symmetrically fixedly connected inside the circular hole 36. The first filter cloth, the second filter cloth and the third filter cloth are slidably connected inside the purification frame 13 respectively, and the densities of the first filter cloth, the second filter cloth and the third filter cloth are dense in sequence. After the insertion rod 34 enters the interior of the circular hole 36, it rubs against the rubber block 37, and then the friction force increases. The rubber block 37 wraps the insertion rod 34 to achieve the connection between the cover plate 25 and the purification frame 13. After the connection is released, the cover plate 25 is taken out to achieve an open top of the purification frame 13, which is convenient for taking out the first filter cloth, the second filter cloth and the third filter cloth in sequence, and convenient for cleaning them. The design of the first filter cloth, the second filter cloth and the third filter cloth having dense densities in sequence greatly improves the filtration of fine particulate smoke.

Finally, the water inside the collection tank 4 will flow to the inside of the water tank 8 through the guide pipe 7.

[0026] In this embodiment, a water pump is fixedly connected to the interior of the water tank 8, a main pipe 49 is fixedly connected to the output end of the water pump, an auxiliary pipe 50 is fixedly connected to the exterior of the main pipe 49, both the main pipe 49 and the auxiliary pipe 50 extend to the interior of the filter tank 1 and are located between the purification frame 13 and the filter screen 48, a branch pipe 51 is fixedly connected to the exterior of the main pipe 49 and the auxiliary pipe 50, a nozzle 52 is fixedly connected to the exterior of the branch pipe 51, by filling the interior of the water tank 8 with water and starting the water pump, the water pump provides power, and the interior of the water tank 8 will be drained to the interior of the main pipe 49 and the auxiliary pipe 50, as the power increases, the water flow will directly enter the interior of the branch pipe 51, and finally be sprayed out by the nozzle 52 to come into contact with the flue gas.

[0027] Implementation plan: After the filter tank 1 is placed at the designated position, the positioning frame 5 is used to form a support with the ground, so that the filter tank 1 is always perpendicular to the ground. Then the water tank 8 is placed outside the positioning frame 5, and the water tank 8 and the collection tank 4 are connected through the guide pipe 7. At the same time, the stabilizing rod 6 will support the inside of the positioning frame 5 to improve the stability of the positioning frame 5 and greatly improve the weighing capacity of the positioning frame 5. By distributing the reinforcement strips 3 on the outside of the filter tank 1, it is prevented that the external force directly contacts the filter tank 1 and causes damage. Then the smoke of the boiler is connected to the air inlet to realize the orderly discharge of the smoke into the inside of the filter tank 1. By filling the inside of the water tank 8 with water and starting the water pump, the water pump provides power to drain the inside of the water tank 8 to the main pipe 49 and the auxiliary pipe 49. Inside the auxiliary pipe 50, as the power increases, the water flow will directly enter the inside of the branch pipe 51, and finally be sprayed out by the nozzle 52 to contact the flue gas. Since the flue gas is in a high temperature state, it evaporates after contacting with water, and then the light particles in the flue gas extend upward, and the fixed particles in the flue gas increase in mass due to the wetting effect of water, and then it is easier to settle under the action of gravity. Then the rising fine particles are filtered by the purification frame 13, and the purified gas is discharged through the outlet pipe 2. When the flue gas is treated for a long time, the internal through hole of the purification frame 13 is blocked, affecting the treatment effect. By extending the stop rod 16 to the outside, the horizontal groove 15 limits the stop rod 16, so that it moves along the predetermined route and passes through The outside of the filter tank 1 extends, and the second limiting ring 18 will move with the stop rod 16, slide inside the first limiting ring 17, and squeeze the first spring 19. The first spring 19 is compressed, and after the stop rod 16 is pulled, its inclined portion will be directly below the receiving bar 22, and then the compression of the receiving bar 22 will be released, and then the telescopic energy storage of the second spring 20 will be released, and the sleeve 21 will drop synchronously and squeeze one end of the extrusion rod 12, and then the extrusion rod 12 will expand from a parallel state to an inclined state inside the through groove 11. After the extrusion rod 12 is expanded, the pressure on the receiving block 24 will be released, and then the purification frame 13 will be lifted outward, and then the slot 23 will be separated from the outside of the fixing column 10, and the removal of the purification frame 13 will be quickly completed. The clamping block 29 is then rotated in the V-shaped groove 31, and the clamping block 29 is fixed and limited by the V-shaped groove 31. After the clamping block 29 enters the V-shaped groove 31, the cylinder 30 slides in the sleeve 26 under the telescopic energy storage of the third spring 35, and approaches the linkage disk 28, and then generates a pulling force on the insertion rod 34, so that the insertion rod 34 is retracted from the inside of the circular hole 36 into the inside of the sleeve 26, and then the connection between the cover plate 25 and the purification frame 13 is released.The cover plate 25 is taken out to realize that the top of the purification frame 13 is open, so that the first filter cloth, the second filter cloth and the third filter cloth can be taken out in sequence for easy cleaning. The first filter cloth, the second filter cloth and the third filter cloth are designed to be densely packed in sequence, which greatly improves the filtration of fine particulate smoke. When the water carries large particles and falls due to gravity, it will directly enter the interior of the collection tank 4. At the same time, the filter screen 48 will separate the large particles from the water, and the large particles will directly fall on the top of the filter screen 48. By connecting the output end of the motor to the turntable 39, the positioning column 40 follows the turntable 3 9 moves, slides inside the swing rod 41, and generates thrust. At the same time, the plug shaft limits the bottom end of the swing rod 41, so that the swing rod 41 swings with the plug shaft as the force point. Finally, the tooth plate 42 and the tooth groove 45 engage with each other, generating thrust on the slide rod 44. Since the clamping ring 43 limits the slide rod 44, the slide rod 44 reciprocates inside the clamping ring 43. At the same time, the extension plate 46 drives the brush 47 to rub the surface of the filter screen 48 to clean the filter screen 48, and at the same time, it can also accelerate the filtering effect. Finally, the water inside the collection tank 4 will flow to the inside of the water tank 8 through the guide pipe 7.
