Description

Technical Field

[0001] The utility model relates to the technical field of acid removal for hazardous waste incineration, and specifically, to an acid removal tower for hazardous waste incineration. Background Art

[0002] During the incineration of hazardous waste, a large amount of acidic gases (such as sulfur oxides and hydrogen chloride) are often generated, and these gases are highly harmful to the environment and health. The acid removal tower is one of the key devices for removing these acidic gases.

[0003] After further retrieval, it is found that an acid removal tower for hazardous waste incineration disclosed in the authorized announcement number CN218963525U, through specific technical structure settings, effectively solves the problem that when the outer wall of the existing acid removal tower for hazardous waste incineration needs to be cleaned of ash, the air duct connected to the acid removal tower will interfere with the ash cleaning mechanism. In this case, the operator needs to remove the air duct from the acid removal tower, and the removal of the air duct is too time-consuming, reducing the ash cleaning efficiency of the outer wall of the acid removal tower.

[0004] However, when the above existing technology is actually used, there are still many defects. For example, the acid removal tower is placed outdoors for a long time, resulting in a large amount of dust adhering to the surface of the acid removal tower, and the dust on the surface of the carbonic acid tower needs to be cleaned. When the ash cleaning mechanism in the above technology cleans the dust on the outer wall of the acid removal tower, the air duct needs to be detached from the top of the acid removal tower. This ash cleaning method is relatively complex, and the spray water used in conjunction with the ash cleaning mechanism cannot be recycled and reused. Therefore, a simple and easy-to-operate ash cleaning mechanism is needed, and the function of recycling and reusing the spray water can be achieved. Content of the Utility Model

[0005] The purpose of the utility model is to provide an acid removal tower for hazardous waste incineration, which solves the problem that when the ash cleaning mechanism in the existing technology cleans the dust on the outer wall of the acid removal tower, the air duct needs to be detached from the top of the acid removal tower. This ash cleaning method is relatively complex, and the spray water used in conjunction with the ash cleaning mechanism cannot be recycled and reused. Therefore, a simple and easy-to-operate ash cleaning mechanism is needed, and the function of recycling and reusing the spray water can be achieved.

[0006] The utility model provides the following technical solution: an acid removal tower for hazardous waste incineration, including a base, an acid removal body, and an induced draft fan. A receiving pool is fixedly installed inside the base, a mounting seat is fixedly installed inside the receiving pool, the acid removal body is fixedly installed at the top of the mounting seat, a connection port is installed through the outer wall of the acid removal body, a lifting mechanism is fixedly installed on one side of the top of the base, and a spray mechanism and a cleaning mechanism are slidably sleeved outside the acid removal body through the lifting mechanism.

[0007] As a preference of the above technical solution, a filter screen is fixedly installed at the top inside the receiving pool, a filter layer is fixedly installed below the filter screen, a suction pump is fixedly installed on the top of the base near one side of the receiving pool, the input end of the suction pump is connected through a pipeline to one side of the receiving pool in a penetrating manner, and the output end of the suction pump is fixedly connected with a hose.

[0008] As a preference of the above technical solution, the lifting mechanism includes a column and a shaft seat. The column is fixedly installed on the top of the base. A rack is installed on one side of the column through a groove opened. A sliding groove is opened on the side of the column away from the rack. A slider is slidably installed inside the sliding groove. One side of the slider away from the sliding groove is fixedly connected with a sliding seat. One side of the sliding seat close to the rack is fixedly connected with a shaft seat. One side of the shaft seat away from the sliding seat is fixedly connected with a spraying mechanism and a cleaning mechanism through a connecting seat. A gear is installed inside the shaft seat through a connecting rod. The gear is meshed with the rack. A motor is installed on the outer side of the shaft seat through a mounting plate. The output end of the motor is fixedly connected with the shaft rod of the gear through a shaft rod. When the motor is energized and runs, the gear is driven to rotate. The rotating gear moves up and down on one side of the rack. The gear moving up and down drives the first mounting sleeve and the second mounting sleeve to move up and down on the outer wall of the deacidification body through the shaft seat and the connecting seat. The shaft seat moving up and down drives the sliding seat to move up and down on the outer side of the column, and the slider inside the sliding seat avoids the shaft seat from falling off when moving up and down on the outer side of the column through the sliding groove inside.

[0009] As a preference of the above technical solution, the spraying mechanism includes a first mounting sleeve. The first mounting sleeve is slidably sleeved on the outer side of the deacidification body. A spray pipe is fixedly installed inside the first mounting sleeve through a groove opened. Nozzles extending to the inner side of the first mounting sleeve are equidistantly installed inside the spray pipe. One side of the spray pipe is fixedly connected with the output end of the hose through a pipeline. When the suction pump is energized and runs, the water inside the receiving pool is conveyed into the spray pipe through the hose, and at the same time, the water inside the spray pipe is sprayed onto the outer wall of the deacidification body through the nozzles.

The bottom end of the second mounting sleeve and the top end of the first mounting sleeve are fixedly connected by a connecting rod. The second mounting sleeve moving up and down drives the brush head to brush the outer wall of the deacidification body through the telescopic rod. The function of cleaning the outer wall of the deacidification body is realized by the water sprayed by the nozzle in cooperation with the brushing of the brush head. The elastic force of the spring in cooperation with the telescopic movement of the telescopic rod can make the brush head closely adhere to the outer wall of the deacidification body, so that the brush head can better brush the outer wall of the deacidification body.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the present utility model, when the suction pump is energized and operates, the water inside the receiving pool is conveyed into the interior of the spray pipe. Meanwhile, the water inside the spray pipe is sprayed onto the outer wall of the deacidification body through the nozzle. Then, the operator controls the motor to be energized and operate through the controller, driving the gear to move up and down on one side of the rack. The moving gear drives the first mounting sleeve and the second mounting sleeve to move up and down on the outer wall of the deacidification body through the connecting seat. The moving first mounting sleeve sprays the water sprayed by the nozzle onto the outer wall of the deacidification body for water washing. At the same time, the moving second mounting sleeve drives the spring to brush the outer wall of the deacidification body through the telescopic rod. The function of cleaning the outer wall of the deacidification body is achieved by the water sprayed by the nozzle in cooperation with the brushing of the brush head. This ash cleaning method does not require the conduit to be detached from the top of the deacidification body to clean the outer wall of the deacidification body. The receiving pool is used to receive the cleaning water, and the larger impurities in the cleaning water are preliminarily filtered through the filter screen. The fine impurities in the cleaning water are adsorbed by the filter layer. The adsorbed water is stored at the bottom of the receiving pool, facilitating the suction pump to suck the treated water inside the receiving pool back into the spray pipe for recycling, realizing the function of recycling the cleaning water, avoiding the problem of water resource waste, and improving the energy conservation and environmental protection performance of the device.

Then, the operator controls the motor 505 to energize and operate through the controller 11, driving the gear 504 to move up and down on one side of the rack 502. The moving gear 504 drives the first mounting sleeve 601 and the second mounting sleeve 701 to move up and down on the outer wall of the deacidification main body 4 through the connecting seat. The moving first mounting sleeve 601 sprays the water sprayed by the spray head 603 onto the outer wall of the deacidification main body 4 for water washing.

[0025] Working principle: The waste incinerator is externally connected through the connection port 401 to facilitate the flue gas generated by the combustion of hazardous waste to enter the deacidification main body 4. The deacidification main body 4 performs deacidification treatment on the flue gas. At the same time, the operator controls the induced draft fan 9 to energize and operate through the controller 11, and the suction force sucks the processed gas inside the deacidification main body 4 into the smoke outlet pipe 10 through the conduit 8, and the gas is discharged through the smoke outlet pipe 10.

[0026] When the outer wall of the deacidification body 4 needs to be cleaned, the water in the receiving pool 2 is conveyed into the internal water delivery nozzle 602 by the energized operation of the suction pump 203. At the same time, the water in the internal water delivery nozzle 602 is sprayed onto the outer wall of the deacidification body 4 through the nozzle 603. Then, the operator controls the energized operation of the motor 505 through the controller 11 to drive the gear 504 to move up and down on one side of the rack 502. The moving-up-and-down gear 504 drives the first mounting sleeve 601 and the second mounting sleeve 701 to move up and down on the outer wall of the deacidification body 4 through the connecting seat. The moving-up-and-down first mounting sleeve 601 sprays the water sprayed by the nozzle 603 onto the outer wall of the deacidification body 4 for water washing. At the same time, the moving-up-and-down second mounting sleeve 701 drives the spring 704 to brush the outer wall of the deacidification body 4 through the telescopic rod 702. The function of cleaning the outer wall of the deacidification body 4 is realized by the water sprayed by the nozzle 603 in cooperation with the brushing of the brush head 703.

[0027] And the receiving pool 2 is used to receive the cleaned water. The larger impurities in the cleaned water are preliminarily filtered through the filter screen 201. The fine impurities in the cleaned water are adsorbed through the filter layer 202. The adsorbed water is stored at the bottom of the receiving pool 2, which is convenient for the suction pump 203 to suck the treated water in the receiving pool 2 back into the internal water delivery nozzle 602 for recycling, so as to realize the recycling of the cleaned water.
