Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to a waste gas purification device for chemical raw material production. Background Art

[0002] In the field of industrial waste gas treatment, the scrubber, as a common and key equipment, undertakes the important task of purifying waste gas. During its operation, the spray water is continuously recycled to efficiently absorb harmful pollutants in the waste gas.

[0003] The existing washing tower spray water circulation mostly relies on external recovery devices. Such devices have complex structures and high investment costs from purchase to installation. Moreover, in the actual factory environment, due to space layout limitations, installation is difficult. When the external recovery device is in operation, additional power support is required, which runs counter to the current concept of energy conservation and emission reduction. At the same time, some washing towers are equipped with filter elements to filter the spray water, but the filter elements will soon be clogged with impurities under long-term high-intensity work due to the lack of a reasonable and effective cleaning mechanism. Once the filter element is clogged, not only the filtering effect will be deteriorated, but the service life will also be greatly shortened, so the filter element needs to be replaced frequently, which will increase the operating cost of the washing tower.

Plate 10, and the side of the first end plate 10 facing away from the water storage cylinder 9 is fixedly installed on the rear side of the circulating water tank 3, and the second end plate 11 is fixedly installed on the other side of the water storage cylinder 9, and a partition plate 29 is fixedly installed in the water storage cylinder 9, and a plurality of filter element connecting seats 12 are fixedly installed on one side of the partition plate 29, and the filter element 13 is connected to the filter element connecting seat 12 with a thread, and a cleaning mechanism 14 is movably installed between the plurality of filter elements 13. The cleaning mechanism 14 includes a plurality of first wrapping rods 15, and the second wrapping rods 16 are rotatably connected on both sides of the first wrapping rod 15. The inner sides of the first wrapping rod 15 and the second wrapping rod 16 are movably installed with mounting inserts 17, and the mounting inserts 17 are movably installed with scrapers 18.

[0023] like Figure 1-Figure 2 As shown, the lower end of the water storage cylinder 9 is fixedly connected to a waste pipe 19, and the waste pipe 19 extends through the base 1 to the outside of the base 1 and is fixedly connected to a valve, the middle of the first end plate 10 is fixedly connected to the input end of the circulating pump 6 with a second connecting pipe 20, and the second connecting pipe 20 is a variable diameter pipe whose diameter gradually increases from the first end plate 10 toward the circulating pump 6, and a water inlet pipe 21 is fixedly installed in the middle of one side of the second end plate 11.

[0024] like Figure 2-Figure 5As shown, a mounting slot 24 is provided in the first wrapping rod 15, and a mounting slot 24 is also provided on the inner side of the second wrapping rod 16. A hoop structure composed of a first wrapping rod 15 and two second wrapping rods 16 can be inserted into the outer side of the filter element 13 to provide conditions for the installation and movement of the scraper 18. A bottom plate 25 is fixedly installed on the scraper 18 relative to one side of the installation plug 17. A plurality of first compression springs 26 are fixedly connected between the bottom plate 25 and the installation plug 17, and the scraper 18 is arranged obliquely. With the help of the force of the plurality of first compression springs 26, the scraper 18 can be used to make the side of the scraper 18 away from the bottom plate 25 to be pressed against the outer side of the filter element 13 with appropriate pressure. A connecting frame 27 is fixedly connected between the plurality of first wrapping rods 15, and a connecting frame 27 is inserted in the middle of the connecting frame 27. A pull rod 22, one end of which passes through the partition 29 and extends into the second connecting pipe 20 and is fixedly installed with a piston 23. A second compression spring 28 is mounted on the outside of the piston 23. One side of the second compression spring 28 abuts against one side of the connecting frame 27, and the other side of the second compression spring 28 abuts against one side of the partition 29. The piston 23 is inserted into the second connecting pipe 20, and when the circulating pump 6 is started, the negative pressure of the circulating pump 6 is utilized to move the piston 23 from the narrow aperture in the second connecting pipe 20 to the wide aperture in the second connecting pipe 20, so that the pull rod 22 cooperates with the connecting frame 27 to synchronously pull multiple groups of first wrapping rods 15, second wrapping rods 16, installation inserts 17, and scrapers 18 to move on the outside of the corresponding filter element 13, so that the attachments on the outside of the filter element 13 can be cleaned.

[0025] It should be noted that the utility model is a waste gas purification device for chemical raw material production. When purifying the waste gas entering the washing tower 2, the circulation pump 6 is first started by the external main controller, so that the negative pressure generated by the circulation pump 6 attracts the piston 23 toward the circulation pump 6 through the second connecting pipe 20, so that the piston 23 pulls the connecting frame 27 toward the circulation pump 6 through the pull rod 22, and then the connecting frame 27 gradually compresses the second compression spring 28 toward the side of the partition 29 during movement, and the connecting frame 27 also synchronously drives multiple groups of first wrapping rods 15 and second wrapping rods 16 to move outside the corresponding filter element 13, so that the first wrapping rod 15 and the second wrapping rod 16 use the inner mounting insert 17 to cooperate with the first compression spring 26 and the bottom plate 25 to drive the scraper 18 to move radially along the outer surface of the filter element 13, so that the auxiliary material on the outside of the filter element 13 is scraped off with the help of the mounting insert 17. When the piston 23 moves to the wide diameter of the second connecting pipe 20, due to the piston 23 and the first compression spring 26, the scraper 18 is moved radially along the outer surface of the filter element 13. A water inlet channel is generated between the two connecting pipes 20, so that the spray water in the circulating water tank 3 can be sucked into the first end plate 10 in cooperation with the water storage cylinder 9 and the water inlet pipe 21, and then transported to the first connecting pipe 7 through the first end plate 10, the second connecting pipe 20, and the circulating pump 6, so that the spray water is diverted to multiple spray pipes 5 through the first connecting pipe 7, and the waste gas in the washing tower 2 can be sprayed. When the waste gas treatment operation is completed, the circulating pump 6 is turned off. At this time, in the absence of negative pressure suction caused by the rotation of the impeller of the circulating pump 6, the second compression spring 28 stretches and rebounds and pushes the connecting frame 27 toward the second end plate 11, so that the connecting frame 27 drives multiple groups of first wrapping rods 15, second wrapping rods 16, installation inserts 17, and scrapers 18 to reset and move, thereby realizing the cleaning of the auxiliary materials on the outer surface of the filter element 13 again after shutdown, and after a certain period of shutdown, the attachments and other impurities hanging in the water storage cylinder 9 are precipitated, and the valve at one end of the waste pipe 19 is opened to discharge the impurities.
