[0004] Although the above technical solution has a certain flue gas purification effect, the flue gas dust reduction requires continuous use of water and lacks a water circulation structure that can recycle the dust reduction water, resulting in a large waste of water resources in the flue gas treatment process.

[0005] Therefore, those skilled in the art provide a flue gas collection and processing device for rubber asphalt production to solve the problems raised in the above background technology. Utility Model Content

[0022] See also Figure 1-4A flue gas collection and processing device for rubber asphalt production and processing includes an air collecting bin 1, an induced draft fan 2 is fixedly connected to the inner wall of the air collecting bin 1, a dust reduction water circulation mechanism 3 is arranged inside the air collecting bin 1, and the dust reduction water circulation mechanism 3 includes a water pump 301, the output end of the water pump 301 is fixedly connected to a water outlet pipe 302, the outer surface of the water outlet pipe 302 is fixedly connected to the inner wall of the air collecting bin 1, the left side of the air collecting bin 1 is fixedly connected to an air intake pipe 4, and the bottom end of the air intake pipe 4 is fixedly connected to an air collecting hopper 5. By setting the air collecting hopper 5, the air intake range of the bottom end of the air intake pipe 4 can be expanded, thereby facilitating the guidance and collection of the flue gas generated in the production and processing of rubber asphalt into the air collecting bin 1 for treatment.

[0023] The input end of the water pump 301 and the back of the air collecting bin 1 are fixedly connected to a water inlet pipe 310, the front of the air collecting bin 1 is fixedly connected to a button controller 311, and the bottom of the air collecting bin 1 is fixedly connected to four support legs 6, and the bottom end of each support leg 6 is fixedly connected to a support seat 7. By setting the support legs 6, it is convenient to stably support the air collecting bin 1 and provide sufficient placement space for other pipeline structures at the bottom of the air collecting bin 1.

[0024] The interior of the gas collecting bin 1 is slidingly connected with the first filter drawer 303 and the second filter drawer 304, respectively. The inner wall of the gas collecting bin 1 is fixedly connected with the ionization net 306 and the dust collecting plate 307, respectively. The back of the gas collecting bin 1 is fixedly connected with a shock-absorbing support plate 8, and the upper surface of the shock-absorbing support plate 8 is fixedly connected to the outer surface of the water pump 301. The first filter drawer 303 and the second filter drawer 304 themselves are composed of plates and drawer frames with good filtering properties. The first filter drawer 303 can mainly filter and carry solid particles and sewage impurities, and water flows into the bottom of the gas collecting bin 1. The second filter drawer 304 can mainly filter and carry impurities in the flue gas again, thereby increasing the cleanliness of the flue gas discharged. By setting the shock-absorbing support plate 8, the water pump 301 can be stably supported with the help of the back of the gas collecting bin 1, and it itself has a certain shock-absorbing effect.

[0025] The bottom end of the gas collecting bin 1 is fixedly connected to a solenoid valve 308, and the output end of the solenoid valve 308 is fixedly connected to a waste pipe 309. The induced draft fan 2, the water pump 301, the ionization network 306 and the solenoid valve 308 are all electrically connected to the button controller 311 through wires. The outer surface of the input end of the water pump 301 and the outer surface of the output end of the water pump 301 are fixedly connected to a sealing ring 11, the inner wall of one sealing ring 11 is fixedly connected to the outer surface of the outlet pipe 302, and the inner wall of the other sealing ring 11 is fixedly connected to the outer surface of the water inlet pipe 310. By setting the sealing ring 11, the connection between the outer surface of the input end of the water pump 301 and the water inlet pipe 310 and the output end of the water pump 301 and the outlet pipe 302 can be reinforced respectively, thereby preventing water leakage between each two.

[0026] One end of the water outlet pipe 302 away from the water pump 301 is fixedly connected to the spray head 305, the front of the first filter drawer 303 is fixedly connected to the first movable handle 9, and the front of the second filter drawer 304 is fixedly connected to the second movable handle 10. By setting the first movable handle 9 and the second movable handle 10, both can be rotated flexibly and appropriately, and then after being grasped, the first filter drawer 303 and the second filter drawer 304 can be easily pulled out of the gas collecting bin 1 and cleaned.

[0027] The working principle of the present invention is as follows: when in use, the first filter drawer 303 is drawn out of the gas collecting bin 1 in advance, and then a sufficient amount of water for dust reduction is injected into the gas collecting bin 1 from the entrance of the first filter drawer 303, and some other auxiliary solvents for absorbing harmful gases in the flue gas can be added to the water, and then the first filter drawer 303 is pushed into the gas collecting bin 1, and then the flue gas generated in the production and processing of rubber asphalt is guided to the bottom of the gas collecting hopper 5, and the button controller 311 is operated to control the induced draft fan 2 to be energized and the flue gas is introduced from the bottom of the gas collecting hopper 5 into the gas collecting bin 1, and at the same time, the button controller 311 controls the ionization network 306 to be energized, and the flue gas that has just entered the gas collecting bin 1 is ionized by the ionization network 306, and the particles in the flue gas are charged and fall on the dust collecting plate 307 or near the dust collecting plate 307, and then the water pump 301 controlled by the button controller 311 is energized to draw the water at the bottom of the gas collecting bin 1 through the spray head 305 After the ionized flue gas is sprayed downward, most of the particulate matter and harmful gases are settled and absorbed. The first filter drawer 303 carries the particulate matter and absorbs the harmful gases dissolved in the water and allows the cleaner water to flow into the bottom of the gas collecting bin 1. The second filter drawer 304 further filters the ionized and settled flue gas, thereby achieving the effect of flue gas treatment. The filtration of the first filter drawer 303 and the repeated pumping of the water pump 301 can realize the recycling of dust-reducing water, which plays a role in fully utilizing and saving water resources. When the wastewater in the gas collecting bin 1 needs to be replaced, the operation button controller 311 controls the solenoid valve 308 to energize and connect the gas collecting bin 1 and the waste pipe 309 to discharge the wastewater from the waste pipe 309. The design of the flue gas collection and processing device for the entire rubber asphalt production and processing effectively solves the problem of large waste of water resources in the flue gas treatment process due to the lack of a water circulation structure that can recycle dust-reducing water.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
