Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, and in particular to a flue gas pretreatment device. Background Technology

[0002] Flue gas is a mixture containing tiny solid particles, liquid droplets, and gases produced during combustion or other chemical reactions. It typically consists of visible smoke and invisible gases, such as exhaust fumes generated during fires or industrial processes. Flue gas may contain harmful substances that can impact the environment and human health.

[0003] Existing treatment devices cannot monitor the state of the filter plates during the filtration process, and the filter plates gradually become saturated due to the adsorption of pollutants during use, thus losing their filtration effect. To overcome these disadvantages, this utility model provides a flue gas pretreatment device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a flue gas pretreatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flue gas pretreatment device, comprising a base plate, a filter box fixedly connected to the top of the base plate, a first fan outlet on the left side of the filter box, a first fan fixedly connected to the first fan outlet, an air inlet pipe fixedly connected to the left side of the filter box and located at the first fan outlet, a second fan outlet on the right side of the filter box, a second fan fixedly connected to the second fan outlet, a spray chamber fixedly connected to the right side of the filter box, several insertion ports on the front end of the filter box, a detachable filter assembly inside the filter box, an observation assembly on the top of the filter box, a collection port at the bottom of the spray chamber, a waste liquid collection assembly on the top of the base plate and located below the collection port, a first valve at one end of the spray chamber, and several support rods fixedly connected to the top of the base plate and located on one side of the filter box, with spray assemblies at the top of the support rods.

[0006] Furthermore, the detachable filter assembly includes a slide rail fixedly connected to the inside of the filter box and located on one side of the inlet, a filter plate slidably connected on the slide rail, and a handle fixedly connected to one side of the filter plate.

[0007] Furthermore, the observation assembly includes an observation port opened at the top of the filter box, a glass fixedly connected to the observation port, and a cleaning assembly disposed on the glass.

[0008] Furthermore, the cleaning assembly includes a rotating block disposed on the glass, a handle fixedly connected to the top of the rotating block, and a cleaning plate fixedly connected to the bottom of the rotating block.

[0009] Furthermore, the waste liquid collection assembly includes a waste liquid collection chamber fixedly connected to the top of the base plate and located below the collection port, and a second valve is provided at the drain port on one side of the waste liquid collection chamber.

[0010] Furthermore, the spraying assembly includes a water tank fixedly connected to the top of the support rod, a water pump fixedly connected to the water outlet at the bottom of the water tank, a third valve fixedly connected to the water outlet of the water pump, a first water pipe fixedly connected to one end of the third valve, a plurality of second water pipes provided on the first water pipe, and an atomizing nozzle fixedly connected to one end of each second water pipe passing through the spraying chamber and located inside the spraying chamber.

[0011] The beneficial effects of this utility model are:

[0012] In use, this utility model provides a flue gas pretreatment device that allows for quick disassembly and replacement of the filter assembly via a detachable filter component. The filter plate in the filter box can be observed by looking through the glass on the assembly. When the filter plate is observed to be gradually saturated with adsorbed pollutants, it can be disassembled and replaced in a timely manner. This prevents the filter plate from becoming ineffective due to saturation during the filtration process, and avoids a decrease in filtration efficiency due to failure to replace it in time.

[0021] like Figure 1-3 As shown, the detachable filter assembly includes a slide rail 3 that is fixedly connected to the inside of the filter box 2 and located on one side of the inlet 29. A filter plate 4 is slidably connected to the slide rail 3, and a handle 5 is fixedly connected to one side of the filter plate 4 to facilitate the removal and installation of the filter plate 4.

[0022] like Figure 1-3 As shown, the observation assembly includes an observation port 11 at the top of the filter box 2, a glass 12 fixedly connected to the observation port 11, and a cleaning assembly provided on the glass 12 for observing whether the filter plate 4 in the filter box 2 is usable.

[0023] like Figure 1-3As shown, the cleaning assembly includes a rotating block 14 disposed on the glass 12, a handle 15 fixedly connected to the top of the rotating block 14, and a cleaning plate 16 fixedly connected to the bottom of the rotating block 14, for cleaning the glass 12.

[0024] like Figure 1-3 As shown, the waste liquid collection assembly includes a waste liquid collection chamber 20 fixedly connected to the top of the base plate 1 and below the collection port 19. A second valve 21 is provided on the drain port on one side of the waste liquid collection chamber 20 for collecting water that has absorbed impurities in the flue gas.

[0025] like Figure 1-3 As shown, the spraying assembly includes a water tank 22 fixedly connected to the top of the support rod 23. A water pump 24 is fixedly connected to the water outlet at the bottom of the water tank 22. A third valve 25 is fixedly connected to the water outlet of the water pump 24. A first water pipe 26 is fixedly connected to one end of the third valve 25. Several second water pipes 27 are provided on the first water pipe 26.

Then, open the first valve 18 and the second valve 21. The flue gas then enters the air inlet pipe 8. The first fan 7 blows the flue gas into the filter plate 4 for filtration. After passing through the filter plate 4, the second fan 10 sends the filtered flue gas into the spray chamber 17. At this time, the water pump 24 draws water from the water tank 22, and the water flows through the first fan 10 into the spray chamber 17. A water pipe 26 is used to spray water through a misting nozzle 28 on a second water pipe 27. The sprayed water passes through the flue gas in the spray chamber 17 and absorbs water-soluble substances such as sulfur dioxide in the flue gas. The waste liquid that absorbs these substances enters the waste liquid collection chamber 20 through the collection port 19 below the spray chamber 17. Then the flue gas is discharged through one end of the spray chamber 17. During the filtration process, the filter plate 4 is observed through the glass 12 to see if it needs to be replaced. When the glass 12 is covered by impurities on the flue gas, the handle 15 is turned to drive the cleaning plate 16 to rotate and clean one side of the glass 12 located inside the filter box 2.
