Metallurgical engineering plays an important role in modern industry. It is not only related to the rational use of metal resources and environmental protection, but also directly affects the development and progress of all walks of life. A large amount of flue gas will be generated in the metallurgical process, and dust removal equipment is needed to carry out preliminary dust removal treatment on the flue gas.

When the device transports the metallurgical smoke to the inside of the main body shell through the smoke inlet pipe, the smoke is blocked by the mounting plate so that the smoke flows between the two mounting plates, and then the water mist sprayed by the water mist nozzle is used to adsorb the dust in the flowing smoke, and then the adsorbed dust will automatically fall into the dust collecting box under the action of gravity and be collected, which greatly improves the dust adsorption and processing capacity, avoids a large amount of smoke and dust from being retained inside the equipment and affecting normal operation, and makes the device run more stably; but in actual use, there are still the following deficiencies: from a practical point of view, when used for long-term dust removal, a large amount of smoke and dust impurities will be attached to the surface of the filter plate, but the filter plate of the device is fixedly connected to the inside of the flow cavity, which is difficult to clean in time, and the smoke and dust particles are easy to block the filter plate, thereby reducing the dust removal effect.

[0004] Therefore, a metallurgical engineering dust removal device is needed to solve the problem in the prior art that the filter plate of the dust removal device is difficult to clean, resulting in clogging of smoke particles and reducing the dust removal effect. Utility Model Content

[0023] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that a cover is threadedly connected to the top of the water inlet 4, which can flexibly open and close the water inlet 4 and prevent dust from entering the water tank 3 from the water inlet 4 to damage the nozzle 5.

[0024] Further as Figure 3 As shown, it is worth explaining in detail that the nozzle 5 is installed inside the spray box 1, and an electromagnetic booster valve is installed at the front end of the nozzle 5. The electromagnetic booster valve can ensure that clean water is sprayed out from the nozzle 5 at a high speed, fully contacts with the smoke in the spray box 1, and absorbs the dust in the flowing smoke.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that a mounting hole corresponding to the fixing bolt 13 is opened on the top of the adsorption box 10, and the mounting hole and the fixing bolt 13 cooperate to realize the detachable connection between the adsorption box 10 and the activated carbon adsorption plate 11, which is convenient for cleaning and replacement of the activated carbon adsorption plate 11.

[0026] According to the above working process, it can be known that by setting the nozzle 5, the dust in the flowing flue gas can be sprayed, and by setting the activated carbon adsorption plate 11, the odor and harmful gases in the metallurgical smoke can be effectively removed, making the dust removal work more environmentally friendly and avoiding pollution to the environment.

[0027] Further as Figure 4As shown, it is worth explaining in detail that the cleaning mechanism 7 includes a convex frame 701 fixedly connected to the top of the spray box 1, and a slide plate 702 is slidably connected to the inner wall of the convex frame 701, and a servo motor 703 is installed on the top of the slide plate 702, and a threaded rod 704 is fixedly connected to the output end of the servo motor 703, and a rotating seat 705 is installed at the bottom of the threaded rod 704. A mounting frame 706 is fixedly connected to the top of the rotating seat 705, and a cleaning roller 707 is rotatably connected to the inner wall of the mounting frame 706. By setting the cleaning mechanism 7, the mounting frame 706 drives the cleaning roller 707 to move back and forth to clean the surface of the filter plate 6, so as to prevent smoke particles from clogging the filter plate 6 and improve the dust removal effect of the device.

[0030] This solution has the following working process: in actual use, the smoke from the metallurgical workshop enters the spray box 1 from the smoke inlet pipe 2, the nozzle 5 is turned on to spray water to adsorb the dust in the flowing smoke, the smoke after spraying passes through the filter plate 6 and enters the adsorption box 10, the activated carbon adsorption plate 11 adsorbs the smoke after spraying again, and effectively removes the odor and harmful gases in the metallurgical smoke. When there is a lot of smoke attached to the filter plate 6, the servo motor 703 is turned on to drive the threaded rod 704 to rotate, and the threaded rod 704 rotates while driving the mounting frame 706 to rise and fall, and the mounting frame 706 drives the cleaning roller 707 to move back and forth to clean the surface of the filter plate 6.

[0031] In summary: by setting the nozzle 5, the dust in the flowing flue gas can be sprayed, and by setting the activated carbon adsorption plate 11, the odor and harmful gases in the metallurgical smoke can be effectively removed, making the dust removal work more environmentally friendly and avoiding pollution to the environment; by setting the cleaning mechanism 7, the mounting frame 706 drives the cleaning roller 707 to move back and forth to clean the surface of the filter plate 6, avoiding smoke particles from clogging the filter plate 6, and improving the dust removal effect of the device.
