[0028] A bottom plate 1, support rods 2 are fixedly installed around the top of the bottom plate 1, a rectangular plate 3 is fixedly installed on the top of the support rods 2, a dust removal box 4 is fixedly installed on the top of the rectangular plate 3, an air inlet 5 is fixedly installed on the left side of the dust removal box 4, a first exhaust port 6 is fixedly installed on the right side of the dust removal box 4, a filter plate 7 is movably connected to the inner wall of the dust removal box 4, a slide groove 10 is opened on the top of the dust removal box 4 and is located on the left side of the filter plate 7, a handle 8 is fixedly installed on the top of the filter plate 7, and the inside of the filter plate 7 is filled with activated carbon 9;
[0029] A fixing mechanism, which is arranged inside the slide slot 10;
[0030] Among them, the fixing mechanism includes a spring 11, the left end of the spring 11 is fixedly connected to the left end of the slide slot 10, and the right end of the spring 11 is fixedly installed with a round rod 12. The right end of the round rod 12 penetrates the filter plate 7 and extends to the inside of the filter plate 7. A pull rod 13 is fixedly installed on the top of the round rod 12. The top of the pull rod 13 passes through the slide slot 10 and extends to the top of the slide slot 10. The round rod 12 moves to the left to release the fixing effect on the filter plate 7.
[0031] When the operator pulls the pull rod 13 to the left, the round rod 12 will be driven to squeeze the spring 11 to move to the left. When the round rod 12 moves to the outside of the filter plate 7, the fixing effect on the filter plate 7 will be released. At this time, the filter plate 7 can be disassembled and replaced by pulling the handle 8 upward.
[0032] Among them, a desulfurization box 14 is fixedly connected to the right side of the first exhaust port 6, and a first liquid level sensor 15 and a second liquid level sensor 16 located below the first exhaust port 6 are fixedly installed in the interior of the desulfurization box 14 in sequence. A controller 17 is fixedly installed on the front of the desulfurization box 14, and a second exhaust port 18 located above the controller 17 is fixedly installed on the front of the dust removal box 4. A valve No. 19 is fixedly installed on the bottom of the desulfurization box 14, and the bottom of the valve No. 1 19 passes through the rectangular plate 3 and extends to the interior of the rectangular plate 3 and is fixedly connected to a first drain pipe 20.
[0033] The output ends of the first liquid level sensor 15 and the second liquid level sensor 16 are electrically connected to the input end of the controller 17 , and the output end of the controller 17 is electrically connected to the input end of the first valve 19 .
[0034] Among them, a collecting box 21 is fixedly installed at the bottom of the first drainage pipe 20, the bottom of the collecting box 21 is fixedly connected to the top of the bottom plate 1, a No. 2 valve 22 is fixedly installed at the bottom of the right side of the collecting box 21, and a second drainage pipe 23 is fixedly installed on the right side of the No. 2 valve 22.
[0035] The desulfurized lime slurry in the desulfurization box 14 flows into the collection box 21 through the first drain pipe 20 and is then discharged through the second drain pipe 23 .
[0036] A liquid collecting box 24 located on the right side of the desulfurization box 14 is fixedly installed on the top of the rectangular plate 3 , a No. 3 valve 25 is fixedly installed on the top of the liquid collecting box 24 , and a liquid guide pipe 26 is fixedly installed on the top of the No. 3 valve 25 .
[0037] The external lime slurry is introduced into the interior of the liquid collecting tank 24 through the liquid conduit 26 .
[0038] Among them, a water pump 27 located behind the liquid guide pipe 26 is fixedly installed on the top of the liquid collecting box 24, a discharge port 28 is fixedly installed on the left side of the water pump 27, and a liquid suction port 29 is fixedly installed on the bottom of the water pump 27. The bottom of the liquid suction port 29 penetrates the liquid collecting box 24 and extends to the interior of the liquid collecting box 24.
[0039] When the water pump 27 is in operation, the lime slurry in the liquid collecting tank 24 is sucked through the liquid suction port 29 and then discharged into the desulfurization tank 14 through the liquid discharge port 28 .
[0040] The bottom end of the drain port 28 penetrates through the desulfurization box 14 and extends to the interior of the desulfurization box 14 and is fixedly installed with a rectangular box 30 , and a nozzle 31 is fixedly installed at the bottom of the rectangular box 30 .
[0041] The lime slurry discharged from the drain port 28 is first discharged into the interior of the rectangular box 30 and then discharged from the nozzle 31, so that the lime slurry is sprayed more evenly inside the desulfurization box 14, and the flue gas inside the desulfurization box 14 can react chemically with the lime slurry, thereby achieving the purpose of flue gas desulfurization.
[0042] A filter screen 32 located above the rectangular box 30 is fixedly installed inside the desulfurization box 14 , the bottom of the filter screen 32 is fixedly connected to the top of the rectangular box 30 , and the inner surface of the filter screen 32 is fixedly connected to the outer surface of the drain port 28 .
[0043] The design of the filter 32 serves to filter the desulfurized flue gas inside the desulfurization box 14 again.
[0044] The filter screen 32 is filled with limestone 33 .
[0045] The limestone 33 is designed to prevent the flue gas that has not been desulfurized from being discharged from the second exhaust port 18 .
[0046] The working principle and use process of this utility model:
[0047] The flue gas generated by the incineration of garbage enters the dust removal box 4 through the air inlet 5, is filtered and adsorbed by the filter plate 7 and the activated carbon 9, and then is introduced into the desulfurization box 14 through the first exhaust port 6 for desulfurization treatment. The desulfurized flue gas is discharged to the outside through the second exhaust port 18.
[0048] The filter plate 7 and activated carbon 9 will absorb a large amount of smoke and dust when filtered for a long time. At this time, the operator pulls the pull rod 13 to the left, which will drive the round rod 12 to squeeze the spring 11 to move to the left. When the round rod 12 moves to the outside of the filter plate 7, the fixing effect of the filter plate 7 will be released. At this time, the pull rod 13 is pulled upward to achieve the purpose of disassembling and replacing the filter plate 7.
[0049] When it is necessary to desulfurize the flue gas inside the desulfurization box 14, the operator first opens the No. 3 valve 25 to discharge the lime slurry into the interior of the liquid collecting box 24 through the liquid conduit 26, and then starts the water pump 27, which will cause the suction port 29 to absorb the lime slurry inside the liquid collecting box 24, and then discharge it into the interior of the rectangular box 30 through the discharge port 28, and then discharge it into the interior of the desulfurization box 14 through the nozzle 31. At this time, the flue gas inside the desulfurization box 14 reacts chemically with the lime slurry, thereby achieving the purpose of desulfurization of the flue gas. The desulfurized flue gas is filtered through the filter net 32 and then discharged to the outside through the second exhaust port 18.
[0050] When the lime slurry inside the desulfurization box 14 reaches the position of the first liquid level sensor 15, the first liquid level sensor 15 sends a discharge signal to the controller 17, and the controller 17 receives the signal to open the No. 1 valve 19, and then the lime slurry inside the desulfurization box 14 is discharged into the interior of the collection box 21 through the first discharge pipe 20. When the lime slurry reaches the position of the second liquid level sensor 16, the second liquid level sensor 16 sends a stop signal to the controller 17. After receiving the signal, the controller 17 closes the No. 1 valve 19 to achieve the purpose of automatically discharging the lime slurry.
