Description

Technical Field

[0001] The utility model relates to the technical field of smoke purification, in particular to a dust desulfurization processing and collecting device. Background Art

[0002] In the process of industrial production, especially in coal combustion, metallurgy, chemical industry and other industries, a large amount of salt-containing dust is often emitted. These dusts not only cause serious pollution to the environment, but also contain harmful gases such as sulfur dioxide, which pose a threat to air quality and human health. Therefore, it is very important to adopt efficient smoke dust purification and desulfurization treatment methods.

[0003] At present, when purifying smoke, it is first necessary to adjust the flue gas temperature and humidity by spraying water or cooling devices to optimize the desulfurization reaction conditions, and then adopt appropriate desulfurization technology, such as wet desulfurization, that is, by spraying limestone slurry to react chemically with sulfur dioxide in the flue gas to generate solid wastes such as calcium sulfate. At the same time, the limestone slurry can absorb part of the dust, improve the purification effect, and facilitate the purification of smoke. However, in the existing smoke purification process, a large amount of solid waste mixed with the limestone slurry is generated. When processing the mixed waste, in order to reuse resources, the solid waste and the limestone slurry need to be processed separately, which requires a lot of labor and has low work efficiency.

[0004] Therefore, in view of the above problems, it is necessary for the applicant to design a dust desulfurization treatment and collection device to solve the problem. Summary of the invention

[0008] The filter mechanism is arranged inside the guide funnel, and the filter mechanism comprises a mounting plate parallel to the upper end surface of the guide funnel, and a filter net is fixedly arranged inside the mounting plate.

[0009] Furthermore, a mounting screw is movably provided on the top surface of the upper flange, and the lower end of the mounting screw passes through the bottom surface of the lower flange and is threadedly provided with a mounting nut that abuts against the bottom surface of the lower flange.

[0010] Through the above structural design, the upper flange and the lower flange are stably installed by using the mounting screws and the mounting nuts, and the upper flange and the lower flange are tightly connected to prevent the leakage of limestone slurry.

[0012] Through the above structural design, the upper flange and the lower flange are used to stably connect the guide funnel, the valve and the discharge pipe. The valve is convenient for opening or closing the discharge pipe, and the controllability is strong.

[0013] Furthermore, the upper connecting flange and the lower connecting flange are internally disassembled and installed with screws, and the outer surfaces of the screws are threadedly provided with fixing nuts that conflict with the top surface of the upper connecting flange and the bottom surface of the lower connecting flange.

[0014] Through the above structural design, the upper connecting flange, the lower connecting flange and the valve are stably installed by using screws and fixing nuts, and the upper connecting flange, the lower connecting flange and the valve are tightly connected to prevent leakage of limestone slurry.

[0015] Furthermore, a fixing block is detachably mounted on the outer side of the mounting plate, and the fixing block is fixedly connected to the inner surface of the guide funnel.

[0017] Furthermore, a groove is provided on the inner side of the fixing block, and a limiting hole is provided inside the groove. A limiting rod is fixedly provided on the bottom surface of the mounting plate, and the limiting rod is matched with the limiting hole.

[0018] Through the above structural design, when in use, the limiting rod and the limiting hole are used to facilitate the insertion of the installation plate into the groove, thereby facilitating the stable installation of the filter screen and achieving high installation efficiency.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the dust desulfurization treatment and collection device can conveniently install or disassemble the filter screen, and can use the filter screen to separately collect and treat the mixed waste generated when purifying the smoke, and has high working efficiency.

[0029] Through the above structural design, during use, the mounting plate 32 is placed into the groove 31 by using the limiting rod 35 and the limiting hole 34, which is convenient for stably placing the filter net 33. After the filter net 33 is installed, the mixed waste generated during the purification of the flue gas is input into the buffer tank 1 through the liquid inlet pipe 10. Under the action of gravity and the filter net 33, the solid waste will be blocked above the filter net 33, and the waste liquid will flow through the filter net 33 into the guiding funnel 24.

After the filter screen 33 is installed, the mixed waste generated during the purification of the soot is input into the buffer tank 1 through the liquid inlet pipe 10. Under the action of gravity and the filter screen 33, the solid waste will be blocked above the filter screen 33, and the waste liquid will flow through the filter screen 33 into the guiding funnel 24. The waste liquid in the guiding funnel 24 will be discharged through the valve 26 and the liquid discharge pipe 28, which is convenient for separating the solid waste and the waste liquid, thereby enabling the convenient collection and treatment of the mixed waste. When too much solid waste accumulates on the filter screen 33 and it is necessary to clean and replace the filter screen 33, the mounting nut 23 is disassembled so that the mounting nut 23 moves away from the mounting screw 21, and the mounting screw 21 is pulled out, thereby separating the upper flange 20 and the lower flange 22. After the upper flange 20 and the lower flange 22 are separated, the guiding funnel 24 will be detached from the buffer tank 1, facilitating the cleaning of the solid waste on the filter screen 33 and the replacement of the mounting plate 32. The disassembly is convenient and the work efficiency is high.
