[0002] With the rapid development of industrialization, the emission of industrial waste gas is increasing year by year, which contains a large amount of particulate matter and harmful gases, causing serious threat to the environment and human health, the particulate matter in industrial waste gas not only pollutes the atmosphere, but also carries harmful substances such as heavy metals and organic matter, further aggravating environmental pollution. Therefore, how to efficiently trap the particulate matter in industrial waste gas and realize standard emission has become an important issue in the current environmental protection field.

[0003] The traditional industrial waste gas particulate matter trapping device usually adopts single filtering mode, such as cloth bag filtering, electrostatic precipitation or activated carbon adsorption. Although these methods can remove the particulate matter in waste gas to some extent, there are still problems of limited filtering efficiency, easy blocking and damage, complex structure, inconvenient maintenance and high energy consumption.

[0004] In order to solve the above problems, in recent years, multi-stage filtration technology has gradually attracted attention, however, the existing multi-stage filtration type device still has some deficiencies, such as uneven distribution, which leads to excessive load of part of the filtering unit, affects the overall filtering effect, complex structure design, difficult to disassemble and clean, affects the long-term stable operation of the equipment, increases the maintenance difficulty and time cost.

Detailed Implementation

[0024] Example 1: As Figure 1 , 3 As shown, a multi-stage filtration type industrial waste gas particulate matter capture device includes a capture body 1 with an open structure at the top and four through air inlets 10 evenly arranged along the circumference of the side wall, a diversion sleeve 2 sleeved on the outer wall of the capture body 1 and connected to the through air inlets 10 one by one through the air guide pipes 20, and a graded capture unit 3 disposed in the capture body 1.

[0025] The bottom of the main body 1 is provided with a card receiving port 11, the upper end of the main body 1 is fastened with a lifting buckle plate 12, and the diversion sleeve 2 is provided with an inlet pipe 21 for introducing industrial waste gas.

[0026] The graded collection unit 3 includes an exhaust main pipe 30 whose upper end is connected to the lifting buckle plate 12 and whose lower end extends to the outside through the card receiving port 11; four graded collection boxes 31 connected to the side wall of the exhaust main pipe 30 through exhaust branch pipes 310 and corresponding one-to-one with the through air inlet 10; and a card receiving box 32 located at the bottom of each through air inlet 10. The exhaust main pipe 30 is also equipped with a solenoid valve, which adopts existing technology, such as a solenoid valve of model ZC51-15HBX.

[0027] The inner wall of the diversion sleeve 2 is connected to the outer wall of the collection body 1 by eight reinforcing rods 22. The upper end of the lifting buckle 12 is provided with a connecting ring 120 for connecting to an external drive device. The lifting buckle 12 is connected to the upper end of each graded collection box 31 by a linkage rod 121. The reinforcing rods 22 provide a support connection between the diversion sleeve 2 and the outer wall of the collection body 1, which can alleviate the connection pressure at each air guide pipe 20 and evenly distribute the pressure at the connection between the air guide pipe 20 and the through air inlet 10 to various parts of the outer wall of the collection body 1, avoiding local stress. The connection ring 120 can quickly connect to the external drive equipment when the grading and collection unit 3 needs to be disassembled or installed as a whole, which simplifies the disassembly and installation process and significantly improves the operating efficiency. The upper end of the grading and collection box 31 is connected to the lifting buckle plate 12 by the linkage rod 121, so that the pressure at the connection between the exhaust pipe 30 and the lifting buckle plate 12 is evenly distributed to each linkage rod 121, avoiding local stress concentration and improving the overall installation reliability of the grading and collection unit 3.

[0028] like Figure 2As shown, the graded collection box 31 includes a collection box body 34 that is fastened to the collection body 1 and corresponds to each through air inlet 10, a first filter screen 35, a second filter screen 36, and an activated carbon adsorption frame 37 disposed within the collection box body 34. When the graded collection box 31 treats the industrial waste gas entering it, the first filter screen 35 removes larger particles and impurities, the second filter screen 36 further removes fine particles and suspended solids, and the activated carbon adsorption frame 37 adsorbs harmful gases and organic matter, thus completing deep purification. This graded treatment method can efficiently remove particles from the waste gas. To ensure emissions meet standards for particulate matter and harmful gases, the first filter plate 35 is a metal filter, and the second filter plate 36 is a glass fiber filter. The metal filter has high mechanical strength and wear resistance, making it suitable for treating exhaust gas containing large particles and has a long service life. The glass fiber filter provides a large surface area, effectively capturing fine particles and suspended solids, enhancing filtration capacity, and is suitable for fine filtration. The activated carbon adsorption rack 37 consists of a frame and an activated carbon filling layer inside the frame. Filter plates or grids are installed above and below the activated carbon filling layer to fix the activated carbon and prevent it from moving with the airflow or liquid flow.

[0029] like Figure 4 As shown, a connecting fixing sleeve 38 is provided at the card receiving port 11. Four vertical snap-fit ​​grooves 380 are evenly provided along the circumference inside the connecting fixing sleeve 38. The outer wall of the exhaust pipe 30 is provided with vertical snap-fit ​​strips 300 that correspond one-to-one with the vertical snap-fit ​​grooves 380. When the exhaust pipe 30 extends to the outside through the card receiving port 11, it snaps with the vertical snap-fit ​​grooves 380 on the inner wall of the connecting fixing sleeve 38 through the vertical snap-fit ​​strips 300 on the outer wall of the exhaust pipe 30, thereby providing a support point for the connection and improving the overall installation reliability of the graded collection unit 3.

[0030] The method of using the multi-stage filtration type industrial waste gas particulate matter capture device in this embodiment includes the following steps:

[0031] S1. Industrial waste gas flows into the diversion sleeve 2 through the inlet pipe 21 and into the corresponding graded collection box 31 through each gas guide pipe 20. At this time, larger particles and impurities, such as dust and metal shavings, are removed by the first filter screen 35, and fine particles and suspended solids are further removed by the second filter screen 36. Harmful gases and organic matter, such as volatile organic compounds (VOCs) and odors, are adsorbed by the activated carbon adsorption rack 37.

[0032] S2. The gas processed in step S1 is introduced into the main exhaust pipe 30 through the exhaust branch pipe 310 and discharged through the solenoid valve on the main exhaust pipe 30.

[0033] S3. When it is necessary to disassemble the graded collection unit 3, the entire assembly of the lifting buckle plate 12 and the graded collection unit 3 installed at the bottom of the lifting buckle plate 12 is pulled out from the collection body 1 by an external driving device. When it is necessary to install the graded collection unit 3, the graded collection unit 3 is placed into the collection body 1 by an external driving device, and the lifting buckle plate 12 is fastened to the upper end of the collection body 1.
