[0001] This utility model belongs to the field of purification device technology, specifically a purification device for waste incineration exhaust gas. Background Technology

[0002] Waste incineration flue gas purification devices are comprehensive systems designed to purify the flue gas generated during waste incineration. Their core function is to remove particulate matter, acidic gases, and harmful substances such as nitrogen oxides from the flue gas, ensuring that emissions meet standards. Through a series of physical and chemical treatment processes, the device deeply purifies the flue gas, effectively reducing environmental pollution. Its applications are mainly concentrated in municipal solid waste incineration power plants and industrial waste incineration plants. It is a key technological support for the waste incineration industry to achieve environmental compliance and sustainable development, and is of great significance for protecting the ecological environment and promoting green development. An existing patent (publication number: CN213089824U) discloses a waste incineration power generation exhaust gas purification device. This device utilizes the combined use of a liquid pump, a desulfurizing agent tank, a first circulation pipe, a first circulation pump, a diversion device, a first liquid inlet pipe, a square box, a desulfurization box, an exhaust pipe, a first exhaust fan, a second circulation pump, a second liquid inlet pipe, a sodium hydroxide solution tank, an acid removal box, a first exhaust pipe, a filter box, an activated carbon filter, a filter, an exhaust pipe, a second exhaust fan, a third exhaust fan, a second exhaust pipe, an annular box, and a third liquid inlet pipe to achieve multiple purification through the filter box, the acid removal box, and the desulfurization box. However, during use, the high temperature of the exhaust gas can easily adversely affect the purification tank and the neutralizing agent, thus significantly reducing the purification effect. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a purification device for waste incineration exhaust gas, which effectively solves the problem that the high temperature of the exhaust gas in the existing exhaust gas purification device can easily have an adverse effect on the purification tank and neutralizing agent, thereby greatly reducing the purification effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a purification device for waste incineration exhaust gas, comprising a base, a purification tower fixedly installed at one end of the top of the base, a connecting pipe fixedly installed in the middle of one side of the base, a cooling cylinder fixedly installed at one end of the connecting pipe, an air inlet pipe fixedly installed at one end of the cooling cylinder, one side of the bottom of the cooling cylinder being fixedly connected to the lower part of one side of the purification tower via a support arm, a drain valve fixedly installed in the middle of the bottom of the cooling cylinder, a servo motor fixedly installed at the top of the base, a transmission component provided at the output end of the servo motor, and four atomizing nozzles arranged equidistantly in a ring inside the base. When the servo motor operates, it outputs power to the four atomizing nozzles through the transmission component, causing the four atomizing nozzles to rotate omnidirectionally and spray to cool the high-temperature exhaust gas.

[0005] Preferably, the transmission assembly includes a transmission gear, which is fixedly installed at the output end of the servo motor. A positioning seat is rotatably installed on the side of the transmission gear away from the servo motor. The bottom of the positioning seat is fixedly connected to the top of the cooling cylinder. The lower part of the transmission gear extends into the interior of the cooling cylinder and meshes with an external gear ring. A rotating ring is fixedly installed inside the external gear ring. The inner wall of the rotating ring is fixedly connected to four atomizing nozzles.

[0006] Preferably, limit slip rings are fixedly installed on both sides of the circumference of the rotating ring, and two annular grooves are opened on the inner wall of the cooling cylinder, with the two limit slip rings slidably installed inside the two annular grooves.

[0007] Preferably, a water supply pipe is fixedly installed on one side of the rotating ring, a rotating pipe is fixedly installed in the middle of the water supply pipe, a bushing is rotatably installed on the surface of the rotating pipe, the surface of the bushing is fixedly connected to the inner wall of the cooling cylinder through two support rods, a rotating joint is rotatably installed at one end of the rotating pipe, a water inlet pipe is fixedly installed at the top of the rotating joint, the upper end of the water inlet pipe extends upward to the outside of the cooling cylinder, and the upper end of the water inlet pipe is fixedly connected to the top of the cooling cylinder through a fixed sleeve, and the top end of the water inlet pipe is connected to an external water source.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator connects the air inlet pipe to the exhaust pipe of the waste incinerator. The exhaust gas in the waste incinerator enters the interior of the cooling cylinder through the air inlet pipe. At the same time, the operator starts the servo motor to drive the transmission gear to rotate along the positioning seat. When the transmission gear rotates, it drives the rotating ring to rotate through the external gear ring. When the rotating ring rotates, it drives the two limit slip rings to slide inside the two annular sliding grooves, which increases the stability of the rotating ring when it rotates. When the rotating ring rotates, it drives the four atomizing nozzles to rotate. When the rotating ring rotates, it drives the rotating tube to rotate inside the bushing, thus ensuring the delivery of cooling water while ensuring rotational stability. Meanwhile, external water enters the rotating tube through the inlet pipe, and the water inside the rotating tube enters the rotating ring through the water delivery pipe. The rotating ring sprays the high-temperature exhaust gas evenly from all directions, thereby quickly and effectively cooling it. The cooled exhaust gas then enters the purification tower through the connecting pipe for further purification before being discharged. This allows the exhaust gas purification device to cool the high-temperature exhaust gas in advance during use, avoiding adverse effects of high temperature on the neutralizing agent used in subsequent purification, thus improving the purification effect.

[0013] During use, the operator connects the air inlet pipe 5 to the exhaust pipe of the waste incinerator. The exhaust gas from the waste incinerator enters the cooling cylinder 4 through the air inlet pipe 5. At the same time, the operator starts the servo motor 8 to drive the transmission component.

When the transmission gear 10 rotates, it drives the rotating ring 13 to rotate through the external gear ring 12. When the rotating ring 13 rotates, it drives the two limit slip rings 14 to slide inside the two annular sliding grooves 15, which increases the stability of the rotating ring 13 when it rotates.
