Description

Technical Field

[0001] The utility model relates to the technical field of flue gas purification equipment, in particular to an atmospheric treatment equipment for flue gas purification. Background Art

[0002] Air pollution prevention and control encompasses a wide range of topics, encompassing comprehensive and systematic approaches, including environmental planning and management, energy utilization, and pollution prevention. Flue gas treatment effectively reduces toxic and hazardous substances in flue gas to below specified concentrations to prevent adverse effects such as corrosion and blockage of equipment. The primary purpose of flue gas treatment is to reduce air pollution and protect the environment and human health.

[0003] Before the desulfurization tower desulfurizes the flue gas, the flue gas needs to be passed into the tower body. Since the flue gas contains a large amount of dust and particulate matter, it is often necessary to filter the flue gas through a cyclone dust collector or an electrostatic precipitator. However, in order to better ensure the desulfurization effect of the flue gas, a terminal filtering mechanism is often provided in the flue to further filter the terminal flue gas.

[0004] Currently, most existing filtering mechanisms filter through filter screens, which involves the filtering efficiency of the filter screens and the replacement of the filter screens. In order to ensure the filtering effect, the filter screens need to be replaced periodically, which consumes a lot of time and manpower.

[0005] Therefore, we propose to design an atmospheric treatment equipment for flue gas purification. Utility Model Content

[0024] See also Figure 1-3 The utility model provides an atmospheric treatment equipment for flue gas purification, including a desulfurization tower main body 1, a smoke exhaust pipe 2 is arranged on the top of the desulfurization tower main body 1, a flue 3 is fixedly connected to one side of the outer wall of the desulfurization tower main body 1, a motor 4 is fixedly connected to one side of the outer wall of the flue 3, the driving shaft of the motor 4 passes through the flue 3 and is fixedly connected to a turntable 5, a drum filter 6 is arranged on one side of the turntable 5 close to the middle of the flue 3, and both ends of the drum filter 6 are fixedly connected to an annular frame 7.

[0025] A mounting rod 501 is fixedly connected to the circumference of the turntable 5, and a mounting groove 502 corresponding to the mounting rod 501 is opened on the inner circumference of the annular frame 7. The mounting rod 501 and the mounting groove 502 are matched with each other, which facilitates the disassembly and assembly of the annular frame 7, thereby cleaning and replacing the drum filter 6 in the annular frame 7.

[0026] A movable door 8 is threadedly connected to the side of the flue 3 away from the motor 4, and a through hole 9 is provided at the bottom of the flue 3. A cleaning brush 10 is fixedly connected to the top of the through hole 9 close to the side of the desulfurization tower body 1. The cleaning brush 10 is in contact with the outer wall of the drum filter 6. When the drum filter 6 rotates, the dust outside the drum filter 6 is easily swept away, thereby ensuring the filtering effect of the drum filter 6. Arc grooves corresponding to the annular frame 7 are provided at both ends of the through hole 9 to facilitate the rotation of the annular frame 7 in the arc groove.

[0027] A collecting box 11 is provided at the bottom of the through hole 9, an air hole is opened at the bottom of the flue 3, and a dust-proof net 12 is provided on the inner wall of the air hole. The air hole is connected to the inside of the collecting box 11, so as to form an air flow path of flue 3-through hole 9-collection box 11-air hole-flue 3, so that the flue gas entering the collecting box 11 can re-enter the flue 3, and at the same time, the dust cleaned from the through hole 9 can be blown deeper into the collecting box 11.

[0028] In this embodiment, limiting frames 13 are fixedly connected on both sides of the outer wall of the flue 3, and sliding grooves corresponding to the limiting frames 13 are opened on both sides of the collection box 11. The limiting frames 13 are slidably connected to the corresponding sliding grooves, and the outside of the limiting frames 13 is wrapped with anti-slip rubber sleeves. By sliding the collection box 11 in the limiting frame 13, it is convenient to disassemble and assemble the collection box 11 and dump the dust and impurities inside.

[0029] In this embodiment, an air collecting hood 14 is provided at one end of the flue 3 away from the desulfurization tower body 1. The center of the air outlet of the air collecting hood 14 corresponds to the middle of the drum filter 6, so that the flue gas is concentrated and blown to the center of the drum filter 6, thereby making full use of the drum filter 6 to filter larger dust and some particulate matter in the flue gas.

[0030] During use, the smoke enters the flue 3 through the wind collecting hood 14 and impacts the center of the filter screen of the drum filter 6, thereby filtering the dust and other particles remaining in the smoke.

[0031] During use, the motor 4 is connected to an external power source and started, driving the turntable 5 to rotate, which in turn drives the annular frame 7 and the drum filter 6 to rotate, switching the filter area impacted by the flue gas. The used drum filter 6 area rotates toward the through hole 9. When it passes through the cleaning brush 10 at the top of the through hole 9, it is convenient to sweep the dust collected on the outside of the drum filter 6 and enter the collection box 11. At the same time, some smoke will pass through the gap between the top of the drum filter 6 and the inner wall of the flue 3. This is negligible within the range allowed by this device.

[0032] By constantly switching the impact surface of the drum filter 6, the filter is constantly updated, ensuring the flue gas filtering effect. At the same time, it can also perform a certain degree of automatic cleaning, greatly extending the service life of the filter and eliminating the need for frequent replacement. To replace it, simply open the movable door 8 and pull the annular frame 7 from the mounting rod 501, which is simple to operate and relatively convenient.

[0033] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
