Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a dust collection device for waste gas treatment. Background Technology

[0002] During industrial production, many industries, such as chemical, building materials, and metallurgy, generate large amounts of waste gas containing pollutants such as dust. If this waste gas is discharged directly into the atmosphere without effective treatment, it will not only seriously pollute air quality, causing environmental problems such as smog and acid rain, and endangering human health, but may also have negative impacts on the surrounding ecological environment and residents' lives.

[0003] While existing waste gas dust collection devices can collect and treat dust from waste gases to some extent, they still have many shortcomings. Some devices have poor sealing performance, making them prone to gas leakage during waste gas treatment, leading to reduced treatment efficiency and pollution of the working environment. Furthermore, the installation and replacement of internal filter components are cumbersome, increasing equipment maintenance costs and downtime, affecting production continuity. In addition, the filter structure design of some dust collection devices is not reasonable enough, resulting in limited dust filtration effectiveness and failing to meet increasingly stringent environmental emission standards. Therefore, developing a waste gas treatment dust collection device with good sealing performance, convenient filter component replacement, and excellent filtration effect is of significant practical importance. It can provide strong support for the efficient treatment of industrial waste gases and promote sustainable industrial development. Utility Model Content

[0006] The sealing assembly includes a sealing ring plate 1 fixedly disposed on the outer wall of the dust collection housing and a sealing plate disposed above the dust collection housing. A second sealing ring plate is provided on the outer wall of the sealing plate. A plurality of evenly arranged sealing bolts are inserted on the second sealing ring plate. The sealing bolts pass through the first sealing ring plate and are threadedly connected to a sealing nut.

[0007] Furthermore, the clamping assembly includes a clamping support plate fixedly disposed on the inner wall of the dust collection housing, the clamping support plate having a clamping groove, and a clamping block inserted into the clamping groove.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Identical components are indicated by the same reference numerals.

[0023] This embodiment provides a dust collection device for exhaust gas treatment, including a fixing plate 1, an installation component 2 on the fixing plate 1, a dust collection housing 3 fixedly mounted on the fixing plate 1, a sealing component 4 on the dust collection housing 3, a locking component 5 inside the dust collection housing 3, and a filter component 6 on the locking component 5.

[0024] In this embodiment, the sealing assembly 4 is disposed on the dust collection housing 3 to ensure the airtightness of the dust collection housing 3 and prevent exhaust gas leakage. The sealing assembly 4 includes a sealing ring plate 401 fixedly disposed on the outer wall of the dust collection housing 3 and a sealing plate 402 disposed above the dust collection housing 3. A second sealing ring plate 403 is disposed on the outer wall of the sealing plate 402. A plurality of evenly arranged sealing bolts 404 are inserted into the second sealing ring plate 403. The sealing bolts 404 pass through the first sealing ring plate 401 and are threadedly connected to sealing nuts 405. When it is necessary to install the sealing plate 402, the sealing plate 402 is placed above the dust collection housing 3, so that the second sealing ring plate 403 is aligned with the first sealing ring plate 401. Then, the sealing bolts 404 are inserted and the sealing nuts 405 are tightened. Through the threaded connection of the sealing bolts 404 and the sealing nuts 405, the first sealing ring plate 401 and the second sealing ring plate 403 are tightly pressed together, thereby achieving the sealing of the dust collection housing 3. An air inlet pipe 7 is fixedly installed on the sealing plate 402 to introduce the waste gas to be treated into the dust collection housing 3; an air outlet pipe 8 is fixedly installed below the dust collection housing 3, and the waste gas after dust collection is discharged from the air outlet pipe 8.

[0025] In this embodiment, the mounting assembly 5 is disposed within the dust collection housing 3 for mounting and fixing the filter assembly 6. The mounting assembly 5 includes a mounting support plate 501 fixedly disposed on the inner wall of the dust collection housing 3. The mounting support plate 501 has a mounting groove 502, and a mounting block 503 is inserted into the mounting groove 502. The filter assembly 6 is detachably mounted on the mounting assembly 5 through the cooperation of the mounting block 503 and the mounting groove 502, which facilitates the replacement and maintenance of the filter assembly 6.

[0026] In this embodiment, the filter assembly 6 is used for dust collection and filtration of exhaust gas. The filter assembly 6 includes a filter connecting ring plate 601 fixedly mounted on the inner wall of the mounting block 503, a filter box 602 fixedly mounted on the inner wall of the filter connecting ring plate 601, a plurality of evenly arranged filter vent holes 603 opened at the bottom of the filter box 602, and a dust removal filter element 604 inserted inside the filter box 602. When the exhaust gas enters the dust collection housing 3 from the inlet pipe 7, the exhaust gas first enters the filter box 602. Through the filtration effect of the dust removal filter element 604, dust and other particulate matter in the exhaust gas are intercepted on the dust removal filter element 604, and the filtered exhaust gas is discharged from the filter box 602 through the filter vent holes 603, and finally discharged from the dust collection housing 3 from the outlet pipe 8.

[0027] In this embodiment, the mounting assembly 2 is disposed on the fixed plate 1 and is used to fix the dust collection device in the required working position. Specifically, the mounting assembly 2 includes a first mounting plate 201 and a second mounting plate 202 symmetrically disposed on the outer wall of the fixed plate 1, and mounting through holes 203 are provided on the first mounting plate 201 and the second mounting plate 202. In the actual installation process, fasteners such as bolts can be used to pass through the mounting through holes 203 to fix the first mounting plate 201 and the second mounting plate 202 to the corresponding mounting brackets or equipment, thereby achieving a stable installation of the dust collection device.

[0028] In practical use, a dust collector filter element 604 of appropriate specifications and material can be selected for installation according to the composition of the exhaust gas and the treatment requirements. After a period of use, a certain amount of dust will accumulate on the surface of the dust collector filter element 604, resulting in a decrease in filtration efficiency. At this time, the dust collector filter element 604 needs to be replaced. When replacing, simply loosen the sealing nut 405, remove the sealing plate 402, and then pull out the locking block 503 upwards to remove the filter assembly 6 from the dust collection housing 3. Then, pull out the old dust collector filter element 604, insert the new dust collector filter element 604, and finally reinsert the locking block 503 into the locking slot 502. Install the sealing plate 402 and tighten the sealing nut 405 to complete the replacement operation of the dust collector filter element 604.

[0029] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
