Description

Technical Field

[0001] The utility model relates to the technical field of flue gas dust removal, in particular to a dust removal device for flue gas purification. Background Technique

[0002] In the desulfurization technology of flue gas, limestone powder is added with water to make slurry as an absorbent, which is fully contacted and mixed with the flue gas. Sulfur dioxide in the flue gas reacts with calcium carbonate in the slurry and the air blown in from the lower part of the absorption tower to generate calcium sulfate. After calcium sulfate reaches a certain saturation, it crystallizes to form gypsum dihydrate. The desulfurized flue gas passes through a demister to remove droplets, and then is discharged into the atmosphere through a chimney.

[0003] The existing patent with the publication number of CN214861954U proposes a dust removal device for flue gas desulfurization. By setting a guide groove and a guide block, while restricting the movement path of the door panel, the door panel is kept integral with the placement box. A sealing strip is also arranged between the guide groove and the guide block. After the door panel is lifted and lowered, the sealing performance between the door panel and the placement box is maintained. A sealing gasket is arranged at the upper end of the placement box and the lower end of the partition plate. When the placement box and the partition plate move relative to each other with the door panel closed.

[0004] However, when removing dust from flue gas, it is necessary to clean the impurities in the flue gas through water. The existing methods directly clean and then directly discharge the water source, wasting water resources. It does not have the function of filtering and recycling the water source after cleaning, wasting water resources, and the dust removal effect on flue gas is not good. In view of the above problems, a dust removal device for flue gas purification is proposed for improvement and upgrading. Content of the Utility Model

The circulation pump 44 is installed on a positioning plate 43, and the outer wall of the positioning plate 43 is fixedly connected to the outer wall of the filter box 6. A conduit 45 is provided at the upper end of the circulation pump 44, and a control valve is provided on the outer wall of the conduit 45. One end of the conduit 45 penetrates inside the dust removal box 1, and the extending end is connected to an annular pipe 46. The outer wall of the annular pipe 46 is clamped on the inner wall of the dust removal box 1, and a plurality of spray heads 47 are provided at the bottom of the outer wall of the annular pipe 46.

[0030] The water source in the water tank 41 is pumped by driving the circulation pump 44 on the positioning plate 43, then conveyed along the conduit 45 to the annular pipe 46, and then the impurities in the flue gas are cleaned by using a plurality of spray heads 47. Then the cleaned water source falls into the lower filter box 6. The filter plate 62 is used to filter the impurities and then flows into the water collecting hopper 65. Then the water collecting hopper 65 sends the water source back to the water tank 41 through the connecting pipe 42. At the same time, the staff opens the cover plate 61 and pulls the pull ring 64 to quickly move the filter plate 62 out through the slider 63 to clean the surface impurities, prevent blockage, and facilitate the recycling of the water source while effectively filtering it.

At this time, the circulating pump 44 on the driving positioning plate 43 is used to extract the water source from the water tank 41, and then it is transported along the conduit 45 to the annular pipe 46. Then, several nozzles 47 are used to clean the impurities in the flue gas. After that, the cleaned water source drops into the lower filter box 6, and the filter plate 62 is used to filter the impurities and then flows into the water collecting hopper 65. Then, the water collecting hopper 65 sends the water source back to the water tank 41 through the connecting pipe 42.
