Technical Field
[0001] The utility model relates to the technical field of fly ash circulation treatment, in particular to a device for circulating treatment of incineration fly ash. Background Art
[0002] The incineration of hazardous waste, domestic garbage, and medical waste produces a large amount of fly ash. Fly ash is a hazardous solid waste that contains volatile organic compounds such as chlorobenzenes and dioxins, and heavy metals. Its particles are extremely small and light, making it easy to escape and float in the atmosphere, causing serious pollution to the areas surrounding the waste incineration site. In addition, since fly ash is enriched with toxic substances such as dioxins, which are carcinogenic to humans, it causes great harm to people living near the incineration site. Therefore, it is particularly important to remove the organic matter in the fly ash.
[0003] The utility model with announcement number CN206112955U discloses a sludge incineration fly ash recycling system, including an incinerator, a desulfurization tower, a fly ash collector and a fly ash bin. The fly ash collector includes a smoke pipe, a first 100-blade group and a second 100-blade group. The smoke pipe includes an upper L-shaped pipe and a lower L-shaped pipe that are interconnected. The first 100-blade group is arranged at the bend of the upper L-shaped pipe, and the second 100-blade group is arranged at the bend of the lower L-shaped pipe. The first 100-blade group and the second 100-blade group are respectively provided with a first ash outlet and a second ash outlet at the bottom of the bend of the first L-shaped pipe and the lower L-shaped pipe;
[0004] The above technical solution can collect, treat and recycle sludge incineration fly ash, with good resource utilization effect, reducing the pollution of dioxins and heavy metals in sludge incineration fly ash to the environment, and has good economic value; however, in actual use, after the gas in the device passes through the desulfurization tower for desulfurization, the gas contains water vapor, and the fly ash is easy to stick to the inner wall of the fly ash collector and is not easy to clean. After the fly ash is separated, there is still moisture inside the gas, which is re-sent to the incinerator, affecting the incineration treatment efficiency. At the same time, the device relies on the reaction of the reactor to provide power to promote the fly ash recycling treatment, which is prone to fly ash backflow, affecting the normal progress of the fly ash recycling treatment, and there is no ventilation port inside the device. The incinerator is in a continuously pressurized state, which is prone to explosion, causing safety risks. Utility Model Content

The output shaft of the blower 411 is coaxially connected to the front axle of the wind wheel 410. The left side of the second pipe 41 is welded to the right side of the drying box 40. The right side of the second pipe 41 is welded to the left side of the desulfurization box 30. The right side of the air inlet pipe 43 is welded to the left side of the drying box 40.

[0058] When it is necessary to use the incineration fly ash circulation treatment device, the user first linearly connects the circulation pump 306, the drive motor 411, and the blower 22 to the external power supply, respectively, and turns on the power switches of the circulation pump 306, the drive motor 411, and the blower 22. The circulation pump 306, the drive motor 411, and the blower 22 are powered on and start working, tighten the air outlet valve 420, close the air outlet duct 42, unscrew the air inlet valve 430, and open the air inlet duct 43 to prevent untreated gas from flowing into the outside through the air outlet duct 42 and causing damage to the external environment. Adjust the feed valve 100 according to the size of the material, and adjust The feed pipe 10 is large and small, and the material is fed into the incineration tower 1 through the feed pipe 10 and incinerated by the incineration tower 1. The fly ash generated after the material is incinerated is filtered through the barrier net 212, and impurities are blocked. The fly ash enters the first pipe 21 through the barrier net 212 to prevent impurities from clogging the first pipe 21. The fly ash entering the first pipe 21 is blocked by the partition 210, and large particles of fly ash enter the fly ash cabin 20 through the pipe at the bottom of the first pipe 21 and are collected by the fly ash trough 203. The remaining fine fly ash is blocked by the baffle 211 and falls into the fly ash cabin 20 under the action of gravity. The residual gas enters the desulfurization box 30 through the first pipe 21;
[0059] The circulation pump 306 draws the desulfurization liquid 307 at the bottom of the desulfurization box 30 out to the spray pipe 305. The spray pipe 305 atomizes the desulfurization liquid 307 through the nozzle 3050 at the bottom. The atomized desulfurization liquid 307 reacts with volatile organic substances such as sulfur dioxide in the residual gas entering the desulfurization box 30 to generate compounds such as ammonium sulfate or ammonium sulfite, thereby removing harmful substances in the residual gas. The residual gas passes through the demister 304, and the residual water vapor in the gas passes through the corrugated plate 3040 and condenses and flows back into the desulfurization liquid 307 to be reused. The gas enters the drying box 40 through the second pipe 41. By adjusting the speed of the wind wheel 410 in the second pipe 41, the circulation speed of the gas in the second pipe 41 is adjusted, and the fly ash circulation filtration efficiency is adjusted. The filtered gas is filtered by the drying sponge 401 to further dry the gas. The dried gas passes through the air inlet pipe 43 and flows back into the incineration tower 1 for recycling.
[0060] When the fly ash trough 203 is filled with fly ash, open the side cover 201, remove the filled fly ash trough 203 from the fly ash cabin 20, pour the fly ash in the fly ash trough 203 into the fly ash collection container, reinsert the fly ash trough 203 into the fly ash cabin 20, close the side cover 201, and when the drying sponge 401 is full of water, tighten the air inlet valve 430, close the air inlet duct 43, open the flip cover 400, take out the drying sponge 401 from the drying box 40, put a new drying sponge 401 into the drying box 40, and close the flip cover 401. 00, unscrew the air inlet valve 430, and the air inlet pipe 43 is reopened. When the air pressure in the incineration tower 1 is too high and needs to be reduced, tighten the air inlet valve 430, close the air inlet pipe 43, unscrew the air outlet valve 420, and open the air outlet pipe 42. The treated gas is discharged from the air outlet pipe 42, and the pressure in the incineration tower 1 is reduced. When the pressure is discharged, tighten the air outlet valve 420, close the air outlet pipe 42, unscrew the air inlet valve 430, and open the air inlet pipe 43. The treated gas flows back into the incineration tower 1 for recycling.
