[0035] Example 1

[0036] This embodiment provides a technical solution: a purification device for catalytic combustion in boilers, such as... Figures 1-5 As shown, it includes a boiler purification treatment box, a purification and cleaning moving mechanism, a filter cartridge 4, a moving positioning mechanism, an air inlet valve pipe, a storage and cleaning box, and a pneumatic cleaning assembly.

[0037] The purification and cleaning moving mechanism is installed and connected to the boiler purification treatment box. This mechanism can move left and right within the box, allowing for flexible cleaning. The filter cartridge 4 is installed and connected to this moving mechanism, which can move the filter cartridge 4 to different positions for cleaning. The filter cartridge 4 is located inside the boiler purification treatment box and filters particulate matter from the boiler catalytic combustion exhaust gas. A moving positioning mechanism is installed and connected to the boiler purification treatment box, acting as a movement limiter. This moving positioning mechanism is connected to the purification and cleaning moving mechanism, and the purification and cleaning moving mechanism is connected to the moving positioning mechanism. The limit position allows for stable movement. The air inlet valve pipe is fixed to the lower end of the boiler purification treatment box, allowing the boiler catalytic combustion exhaust gas to be introduced into the boiler purification treatment box. The collection and cleaning machine box is fixed to the front end of the boiler purification treatment box, allowing it to receive and clean the filter cartridge 4 inside the boiler purification treatment box. The pneumatic cleaning component is installed on the upper end of the collection and cleaning machine box with screws. The pneumatic cleaning component can receive high-pressure gas to clean the filter cartridge 4. When high-pressure gas is introduced into the filter cartridge 4, the particles attached to the filter cartridge 4 fall off, thus completing automatic cleaning and making cleaning more convenient. The pneumatic cleaning component is connected to an external air pump, which facilitates the receipt of external high-pressure gas.

[0038] The purification and cleaning moving mechanism includes an electric telescopic cylinder 7 that is screwed onto the outer wall of the rear end of the purification chamber shell 13. The electric telescopic cylinder 7 is easy to install and remove. The telescopic rod of the electric telescopic cylinder 7 passes through the purification chamber shell 13 and is fixedly connected to a multi-type connecting plate 71. When the telescopic rod of the electric telescopic cylinder 7 extends or retracts, it can change the position of the multi-type connecting plate 71 on the purification chamber shell 13. A filter cartridge 4 is installed on the inner side of the multi-type connecting plate 71 by screws. When the position of the multi-type connecting plate 71 changes, it can change the position of the filter cartridge 4, thereby automatically changing the position of the filter cartridge 4 for cleaning. A moving positioning mechanism is fixedly connected to the lower end of the multi-type connecting plate 71. The positioning of the multi-type connecting plate 71 by the lower end moving positioning mechanism makes it more stable when moving.

[0039] The connecting plate 71 is moved left and right by the electric telescopic cylinder 7 and sleeved inside the cleaning machine housing 3, so that it can be moved accordingly for cleaning.

[0040] The cleaning and purifying housing includes a housing shell 3. A corresponding storage slot 32 is provided on the inner rear side of the housing shell 3, through which the connecting plate 71 can pass. The housing shell 3 is fixedly connected to the purification chamber shell 13 through the corresponding storage slot 32, so that it can be stably connected and placed. A left-low-right-high shell 31 is fixedly connected to the lower end of the housing shell 3. The left-low-right-high shell 31 can receive particles falling from inside the housing shell 3. A dust discharge valve 21 is fixedly connected to the lower end of the left-low-right-high shell 31, and the dust discharge valve 21 can be opened to discharge. A pneumatic cleaning component is installed at the upper end of the housing shell 3. The pneumatic cleaning component can deliver gas to the housing shell 3 to filter the filter cartridge 4.

[0041] The pneumatic cleaning assembly includes a positioning end plate 22 and a screw lug 24. The positioning end plate 22 is installed on the cleaning machine housing 3 via the screw lug 24, so that the positioning end plate 22 can be placed stably. A conveying bend 2 is installed on the inner side of the positioning end plate 22, and the positioning end plate 22 can drive the conveying bend 2 to be placed. The lower end of the conveying bend 2 passes through the cleaning machine housing 3 and is equipped with a cleaning cover 23. The conveying bend 2 can receive external high-pressure gas for conveying. The high-pressure gas can be conveyed into the cleaning cover 23, and then discharged into the filter cartridge 4 for dust cleaning after passing through the cleaning cover 23.

[0042] The inlet valve pipe includes a boiler catalytic combustion exhaust gas inlet bend 5 fixed to the lower end of the purification chamber shell 13. The boiler catalytic combustion exhaust gas inlet bend 5 can transport waste gas into the purification chamber shell 13. An inlet valve body 51 is installed on the inner side of the boiler catalytic combustion exhaust gas inlet bend 5. When the inlet valve body 51 on the inner side of the boiler catalytic combustion exhaust gas inlet bend 5 is opened, the exhaust gas can be transported accordingly. The other end of the boiler catalytic combustion exhaust gas inlet bend 5 is connected to the boiler catalytic combustion exhaust gas discharge pipe, which facilitates receiving and transporting.

[0043] During use, the boiler purification treatment box filters particulate matter from boiler exhaust gas through filter cartridge 4. Filter cartridge 4 can move back and forth via a purification and cleaning moving mechanism. Filter cartridge 4 is mounted on a connecting plate 71 of the purification and cleaning moving mechanism. When the connecting plate 71 moves the filter cartridge 4 inside the boiler purification treatment box, the filter cartridge 4 can filter particulate matter from the catalytic combustion exhaust gas input through the intake valve pipe. During cleaning, the electric telescopic cylinder 7 of the purification and cleaning moving mechanism extends, moving the connecting plate 71 forward. The connecting plate 71 then moves the filter cartridge 4 through the corresponding holes in the cleaning moving hole 12 and the corresponding receiving slot 32. The rear end of the connecting plate 71 fills the area of ​​the cleaning moving hole 12, and the connecting plate 71 moves the filter cartridge 4 into the outer shell 3 of the cleaning box. 4 is located below the pneumatic cleaning assembly, and the cleaning cover 23 of the pneumatic cleaning assembly is located above the upper end of the filter cartridge 4. The pneumatic cleaning assembly delivers the input high-pressure gas to the cleaning cover 23 through the conveying bend 2. The cleaning cover 23 then discharges the high-pressure gas into the filter cartridge 4. When the filter cartridge 4 receives the high-pressure gas, it can effectively clean the filtered dust. The fallen dust falls into the left-low-right-high housing 31 and can then be discharged through the dust discharge valve 21 at the lower end of the left-low-right-high housing 31, making it more convenient to clean the filter cartridge 4. After cleaning, the electric telescopic cylinder 7 drives the connecting plate 71 to return to its original position, so that the connecting plate 71 can completely cover the inside of the purification box housing 13. The front end of the connecting plate 71 can effectively fill the area of ​​the cleaning moving hole 12, so that the exhaust gas can only be filtered and discharged through the filter cartridge 4.
