[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figure 1-8 , the present utility model provides a technical solution: a solid waste incineration flue gas dust collector, including a base 1, a heat exchange cylinder 2, a heat exchange pipe 3, a water filling port 4, a drain valve 5, a dust removal and purification box 6, a pump body 7, a support column 8, a bottom plate 9, a movable sleeve 10, a fixing bolt 11, an activated carbon filter screen 12, a cleaning component 13, a movable rod 14, a cleaning brush 15, a positioning plate 16, an auxiliary rod 17 and a fixing cap 18.

[0035] When using this solid waste incineration flue gas dust collector, as Figure 1 , Figure 2 and Figure 3 shown, the right end of the base 1 is fixedly installed with a heat exchange cylinder 2, and a heat exchange pipe 3 is arranged inside the heat exchange cylinder 2. At the same time, the right end of the heat exchange pipe 3 is connected to the flue gas pipe of the solid waste incineration equipment, and the left end of the heat exchange pipe 3 is connected to the dust removal and purification box 6. First, an appropriate amount of cold water is added to the heat exchange cylinder 2 through the water filling port 4, and the cold water completely submerges the heat exchange pipe 3. Then, the high-temperature flue gas generated after incineration is introduced into the heat exchange cylinder 2 through the heat exchange pipe 3. The cold water in the heat exchange cylinder 2 is heat-exchanged by the high-temperature flue gas, and the cold water in the heat exchange cylinder 2 is heated, which is convenient for recycling and reusing the heat. After the cold water is heated, it can be discharged through the drain valve 5 for use;

[0036] The heat-exchanged flue gas enters the dust removal and purification box 6, and the pump body 7 sucks the flue gas in the dust removal and purification box 6 outwards. At the same time, an activated carbon filter screen 12 is inserted and installed in the middle of the dust removal and purification box 6. Through the setting of the activated carbon filter screen 12, it is convenient to filter and purify the flue gas. After the filtering and purification treatment, it is discharged outwards through the pump body 7. Combining Figure 4 , Figure 5 and Figure 6 shown, the bottom plate 9 is snap-fitted and installed at the lower end of the dust removal and purification box 6. Through the setting of the cleaning component 13, the cleaning component 13 is composed of a movable rod 14 rotatably installed in the middle of the bottom plate 9 and a cleaning brush 15 fixedly connected to the upper end of the movable rod 14. By rotating the movable rod 14, the cleaning brush 15 is driven to rotate. The cleaning brush 15 is attached to the lower end of the activated carbon filter screen 12, so as to facilitate the real-time cleaning of the dust adsorbed on the activated carbon filter screen 12, prevent the activated carbon filter screen 12 from being blocked, and thus ensure the smooth progress of the entire filtering process;

[0037] Moreover, after the processing is completed, the fixing bolt 11 can be rotated. The fixing bolt 11 is threadedly connected to both the movable sleeve 10 and the pump body 7. Loosening the fixing bolt 11 releases the limit between the movable sleeve 10 and the support column 8. Then, the bottom plate 9 is pulled downward. The bottom plate 9 drives the sliding between the movable sleeve 10 and the support column 8, moving the bottom plate 9 downward, which facilitates the collection of the swept dust. Moreover, in combination with Figure 7 and Figure 8 As shown, the fixing cap 18 threadedly connected to the outer surface of the auxiliary rod 17 can also be rotated. The fixing cap 18 is disengaged from the positioning plate 16, thereby releasing the limit between the auxiliary rod 17 and the positioning plate 16. Then, the positioning plate 16 is flipped downward. The positioning plate 16 rotates at the left end of the dust removal and purification box 6. The upper end of the positioning plate 16 is disengaged from the auxiliary rod 17, and the positioning plate 16 is disengaged from the activated carbon filter net 12, thereby releasing the limit between the activated carbon filter net 12 and the dust removal and purification box 6. Then, the activated carbon filter net 12 is pulled to the left, and the activated carbon filter net 12 is removed from the dust removal and purification box 6, which facilitates the disassembly, installation, and replacement of the activated carbon filter net 12.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
