Description

Technical Field

[0001] This utility model relates to the field of exhaust gas filtration, specifically to an exhaust gas filtration and purification device for a combustion tower. Background Technology

[0002] A combustion tower is a device used to burn waste or biomass, converting waste into energy and ash through high-temperature combustion. For example, the invention patent application with publication number CN113669743A describes an environmentally friendly waste gas combustion tower that not only fully burns the chemical gases in the waste gas but also continuously supplies air to the treatment chamber to improve the combustion effect and prevent chemical gases from being released into the atmosphere and polluting the environment; it also includes a treatment chamber, a support frame, a first air inlet pipe, an air outlet pipe, and a burner.

[0003] Existing combustion towers typically consist of a combustion chamber and a chimney. The combustion chamber maintains high temperatures to ensure complete combustion of waste, while exhaust gases are emitted through the chimney. However, these exhaust gases are discharged directly without treatment, causing air pollution. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a combustion tower exhaust gas filtration and purification device, which solves the problem of air pollution caused by combustion tower exhaust gas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tail gas filtration and purification device for a combustion tower, comprising a filter tank and a ring pipe, wherein a rotating cylinder is rotatably connected to the middle of the filter tank, a rotating pin is fixedly connected to the edge of the rotating cylinder, the rotating pin is rotatably connected to the filter tank, a filter screen is fixedly connected to the inner side of the rotating cylinder, a cleaning and anti-clogging component is provided on the filter screen, a plurality of nozzles are provided on the inner ring wall of the ring pipe, and a liquid inlet pipe is fixedly connected to the outer ring wall of the ring pipe, the liquid inlet pipe passing through the filter tank and extending to the outside of the filter tank.

[0006] Preferably, sealing rings are embedded in both the upper and lower sections of the rotating drum, and these sealing rings are in contact with the filter tank. The use of sealing rings increases the sealing performance between the rotating drum and the filter tank.

[0007] Preferably, an air inlet pipe is fixedly connected to the top of the filter canister, and an air outlet pipe is fixedly connected to the bottom of the filter canister. The air inlet and outlet pipes facilitate the entry and exit of exhaust gas within the filter canister.

[0008] Preferably, a fixing bracket is fixedly connected to the annular tube, and the other end of the fixing bracket is fixedly connected to the inner wall of the filter tank. The fixing bracket serves to fix the annular tube in place.

[0009] Preferably, a flow guide shroud is fixedly connected to the inner wall of the filter tank, and the flow guide shroud is located between the annular tube and the rotating drum. The flow guide shroud serves to guide the flow of the sprayed solution.

[0010] Preferably, a locking pin is slidably connected inside the rotating drum, and the locking pin engages with the filter tank. A spring is installed inside the rotating drum, one end of which is fixedly connected to the locking pin, and the other end of which is fixedly connected to the inner surface of the rotating drum. The elastic force of the spring causes the locking pin to engage inside the filter tank, thus positioning the rotating drum.

[0011] Preferably, the cleaning and anti-clogging component includes a rotating shaft mounted on the filter screen via bearings. An impeller is fixedly connected to the top of the rotating shaft, a connecting frame is fixedly connected to the middle section of the shaft, and a housing is fixedly connected to the end of the connecting frame. A steel brush is slidably connected to the inner side of the housing, and the steel brush abuts against the filter screen. A spring is provided on the inner side of the housing. By configuring the cleaning and anti-clogging component, the filter screen is prevented from clogging and cleaned, ensuring stable filtration.

[0012] Preferably, one end of the second spring is fixedly connected to the steel brush, and the other end of the second spring is fixedly connected to the inner surface of the housing. By configuring the second spring, the elastic force can be applied to the steel brush, ensuring it remains in contact with the filter screen at all times.

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

[0014] 1. This utility model features a two-stage filter tank with a rotatable drum in the middle. A filter screen is installed inside the drum to filter the exhaust gas from the combustion tower. The filter screen is equipped with a cleaning and anti-clogging component. Additionally, an annular pipe with nozzles is installed inside the filter tank. This annular pipe can deliver a solution to neutralize the exhaust gas through an inlet pipe. After neutralizing the exhaust gas, the solution, guided by a flow guide, impacts the impeller, causing it to rotate. This, in turn, causes a coaxial steel brush to rotate, cleaning the filter screen and preventing clogging, thus ensuring proper temperature filtration of the exhaust gas.

[0015] 2. This utility model sets two pivot pins on the rotating drum. The pivot pins can be inserted into the side of the filter tank. Then, a locking pin supported by a spring is set on the other side of the rotating drum. The locking pin will also be locked into the rotating drum under the action of the spring. In this way, only a pushing force needs to be applied to the rotating drum later, and the locking pin will retract into the rotating drum. The rotating drum can be rotated through the pivot pins, which facilitates the cleaning of the filter screen. Attached Figure Description

A filter screen 4 is fixedly connected to the inner side of the rotating cylinder 2. A locking pin 12 is slidably connected inside the rotating cylinder 2, engaging with the filter tank 1. A spring 13 is installed inside the rotating cylinder 2, with one end fixedly connected to the locking pin 12 and the other end fixedly connected to the inner surface of the rotating cylinder 2. The spring force of spring 13 causes the locking pin 12 to engage inside the filter tank 1, which has a positioning function for the rotating drum 2.

[0023] Please see Figure 1-3The inner wall of the annular pipe 8 is provided with multiple nozzles 81, and the outer wall of the annular pipe 8 is fixedly connected to an inlet pipe 9, which penetrates the filter tank 1 and extends to the outside of the filter tank 1. A fixing bracket 10 is fixedly connected to the annular pipe 8, and the other end of the fixing bracket 10 is fixedly connected to the inner wall of the filter tank 1. The fixing bracket 10 is used to fix the annular pipe 8. A flow guide shroud 11 is fixedly connected to the inner wall of the filter tank 1, and the flow guide shroud 11 is located between the annular pipe 8 and the rotating drum 2. The flow guide shroud 11 is used to guide the sprayed solution.

[0024] Please see Figure 3-4 A cleaning and anti-clogging component 5 is provided on the filter screen 4. This component prevents clogging and ensures stable filtration. The cleaning and anti-clogging component 5 includes a rotating shaft 51 mounted on the filter screen 4 via bearings. An impeller 52 is fixedly connected to the top of the rotating shaft 51.
