Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a comprehensive treatment device for waste gas containing dust. Background Technology

[0002] Currently, various harmful substances are present in dust-laden exhaust gases. To remove these harmful substances, exhaust gases are often treated through multiple processes before being released. However, common integrated exhaust gas treatment systems require gases to pass through multiple stages of equipment before emission. Since not all exhaust gases contain the same harmful substances, sometimes certain stages of treatment are unnecessary, wasting time and reducing treatment efficiency. Utility Model Content

[0003] The purpose of this invention is to address the problem that sometimes waste gas does not need to be treated by a certain part of the equipment, and the time the gas spends in this part of the equipment is unnecessary, thus wasting gas treatment time and reducing gas treatment efficiency. This invention provides a comprehensive treatment device for waste gas containing dust.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A comprehensive treatment device for dust-containing waste gas includes a dust pretreatment shell, a connecting plate fixedly installed on one side of the dust pretreatment shell, and a purification shell fixedly installed at one end of the connecting plate. Multiple partition plates are fixedly installed inside the purification shell, forming multiple expansion chambers between the purification shell and the partition plates. An air inlet pipe is fixedly installed on one side of the dust pretreatment shell, and an air inlet valve is installed inside the air inlet pipe. A dust filtration mechanism is installed inside the dust pretreatment shell. An odor purification mechanism is installed in one expansion chamber of the purification shell, and a waste gas photolysis mechanism is installed in the other expansion chamber of the purification shell. A ventilation connecting hose is installed on the other side of the dust pretreatment shell.

[0006] Preferably, the dust filtration mechanism includes a filter frame, which is slidably inserted into the dust pretreatment housing, and a sealing plate is fixedly installed on one side of the filter frame, and a lifting plate is fixedly installed on one side of the sealing plate.

[0007] Preferably, the sidewall of the purification housing is symmetrically provided with multiple notches and grooves, which are distributed on both sides of multiple expansion cavities and are arranged at equal intervals.

[0008] Preferably, the odor purification mechanism includes a cleaning housing, which is fixedly installed in one of the expansion chambers of the purification housing, and the upper end of the cleaning housing is open. The cleaning housing has symmetrically arranged positioning plates inside, and a support mesh cylinder is slidably inserted between the two positioning plates. Activated carbon particles are arranged inside the support mesh cylinder, and an upper cover plate is provided on the support mesh cylinder. Connecting air pipes are symmetrically arranged at both ends of the cleaning housing.

[0009] Preferably, one end of the supporting mesh cylinder is open, and a U-shaped insert is slidably inserted into the open end of the supporting mesh cylinder, with one side of the U-shaped insert fixedly connected to the upper cover plate.

[0010] Preferably, the waste gas photolysis mechanism includes a transparent photolysis box, which is fixedly installed in another expansion cavity of the purification shell, and both ends of the transparent photolysis box are provided with connecting gas pipes. A UV lamp plate is fixedly installed on the transparent photolysis box, and a catalyst feed pipe is fixedly installed on the side wall of the transparent photolysis box. One end of the catalyst feed pipe passes through the UV lamp plate and is provided with a sealing cap.

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

[0012] 1. In this utility model, by setting up components such as a dust pretreatment shell, a connecting plate, and a purification shell, the gas containing dust is introduced into the dust pretreatment shell through the air inlet pipe. Then, it passes through the set filter screen to remove the dust. Next, the equipment in the purification shell is selected according to the waste contained in the gas. For example, for odor treatment, the ventilation connecting hose can be connected to the connecting air pipe on the side of the cleaning shell, so that the gas will pass through the activated carbon particles in the support mesh cylinder to remove odors. When the gas does not contain other impurities, it can be discharged directly. When the gas still contains other waste, it is discharged for continuous purification. In this way, the gas does not pass through equipment that has no treatment significance in sequence, thereby avoiding the reduction of the gas flow rate and thus accelerating the waste gas treatment efficiency. Furthermore, by matching purification instruments in multiple expansion chambers, it can also adapt to the treatment of various waste gases. Attached Figure Description

[0021] like Figure 1-3As shown, a comprehensive treatment device for dust-containing waste gas includes a dust pretreatment shell 1. A connecting plate 5 is fixedly installed on one side of the dust pretreatment shell 1, and a purification shell 6 is fixedly installed on one end of the connecting plate 5. Multiple partition plates 8 are fixedly installed inside the purification shell 6, and multiple expansion cavities 9 are formed between the purification shell 6 and the multiple partition plates 8. The multiple expansion cavities 9 allow operators to easily combine purification instruments to adapt to the treatment of different harmful substances contained in the waste gas, thereby improving the adaptability of the device. An air inlet pipe 2 is fixedly installed on one side of the dust pretreatment shell 1, and an air inlet valve is installed inside the air inlet pipe 2.

[0022] The dust pretreatment housing 1 is equipped with a dust filtration mechanism, which includes a filter frame 15. The filter frame 15 is slidably inserted into the dust pretreatment housing 1, and a sealing plate 3 is fixedly installed on one side of the filter frame 15. A lifting plate 4 is fixedly installed on one side of the sealing plate 3. The filter frame 15 can be easily removed by the lifting plate 4. The filter frame 15 can filter the dust in the gas, thereby facilitating the subsequent treatment of harmful substances contained in the exhaust gas.

[0023] An odor purification mechanism is installed in one of the expansion chambers 9 of the purification housing 6. This mechanism includes a cleaning housing 18, which is fixedly installed within one of the expansion chambers 9 of the purification housing 6. The upper end of the cleaning housing 18 is open. Symmetrically arranged locking plates 20 are provided inside the cleaning housing 18, and a supporting mesh cylinder 21 is slidably inserted between the two locking plates 20. Activated carbon particles are placed inside the supporting mesh cylinder 21, which can purify odorous gases. A top cover plate 13 is provided on the supporting mesh cylinder 21. One end of the supporting mesh cylinder 21 is open, and a U-shaped insert plate 19 is slidably inserted into the open end. One side of the U-shaped insert plate 19 is fixedly connected to the top cover plate 13. The U-shaped insert plate 19 and the top cover plate 13 allow for easy opening of the supporting mesh cylinder 21, facilitating the purification of the activated carbon particles inside.

[0024] The cleaning housing 18 has connecting air pipes 14 symmetrically arranged at both ends. The purification housing 6 has multiple notches 10 symmetrically opened on the side wall. The multiple notches 10 are distributed on both sides of the multiple expansion chambers 9, and the multiple notches 10 are arranged at equal intervals. The notches 10 facilitate the connection of the pipes.

[0025] The other expansion chamber 9 of the purification housing 6 is equipped with a waste gas photolysis mechanism, which includes a transparent photolysis box 16. The transparent photolysis box 16 is fixedly installed in the other expansion chamber 9 of the purification housing 6, and both ends of the transparent photolysis box 16 are provided with connecting air pipes 22. A UV lamp plate 11 is fixedly installed on the transparent photolysis box 16, and a catalyst feed pipe 17 is fixedly installed on the side wall of the transparent photolysis box 16. One end of the catalyst feed pipe 17 passes through the UV lamp plate 11 and is provided with a sealing cover 12. A ventilation connecting hose 7 is provided on the other side of the dust pretreatment housing 1. With the help of the ventilation connecting hose 7, the gas discharged from the dust pretreatment housing 1 can be easily introduced into any purification instrument.

[0026] In summary: Dust-containing gas is introduced into the dust pretreatment housing 1 through the inlet pipe 2, and then the dust is filtered out by the filter frame 15. Next, the equipment in the purification housing 6 is selected according to the waste contained in the gas. For example, when treating gas containing odors, the ventilation connecting hose 7 on one side of the dust pretreatment housing 1 is connected to the connecting air pipe 14 on the side of the cleaning housing 18. The gas will then pass through the activated carbon particles in the support mesh cylinder 21 to remove odors. When the gas does not contain other impurities, it can be discharged directly. When the gas contains other wastes, such as waste gas that needs to be photolyzed, the gas discharged from the connecting air pipe 14 on one side is connected to the connecting air pipe 22 through the hose. Then, a specific catalyst is added to the transparent photolysis box 16 through the catalyst feed pipe 17, so that the gas enters the transparent photolysis box 16 for purification. In this way, the gas does not pass through equipment that has no treatment significance in sequence, thereby avoiding the reduction of the gas flow rate and thus speeding up the waste gas treatment efficiency. Furthermore, by matching purification instruments in multiple expansion chambers 9, it can also adapt to the treatment of various waste gases.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
