Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment, and in particular to a mixed waste gas treatment device. Background Technology
[0002] Waste gas treatment equipment mainly refers to environmental protection equipment that uses different technologies to recover or remove or reduce harmful components in exhaust gases, thereby protecting the environment and purifying the air, preventing pollution. Dust-type waste gases are generally collected and treated uniformly through waste gas treatment devices, which greatly reduces the environmental pollution caused by dust-type waste gases.
[0003] For the treatment of mixed waste gas containing dust, multi-stage filtration is required to ensure that the waste gas does not pollute the environment when it is discharged. After a period of waste gas treatment, the filter components inside the treatment equipment need to be cleaned after a long period of shutdown. Each shutdown will have a certain impact on daily production.
[0004] Therefore, it is necessary to provide a new mixed waste gas treatment device to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a mixed waste gas treatment device, which solves the problem that existing waste gas treatment devices require long-term shutdown and cleaning of the filter components inside the treatment device after a period of waste gas treatment.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 as well as Figure 4 ,in Figure 1 The main structure of the mixed waste gas treatment equipment provided by this utility model is shown in a three-dimensional view. Figure 1 ; Figure 2 for Figure 1 A magnified structural diagram of A is shown below; Figure 3 The main structure of the mixed waste gas treatment equipment provided by this utility model is shown in a three-dimensional view. Figure 2 ; Figure 4 A top view of the main structure of the mixed waste gas treatment equipment provided by this utility model.
[0024] In the specific implementation process, such as Figures 1-4 As shown, the system includes an exhaust gas treatment box 1. A partition 2 is fixed inside the exhaust gas treatment box 1. The exhaust gas treatment box 1 contains two sets of primary filter layers 8, medium-efficiency filter layers 9, and high-efficiency filter layers 10. The primary filter layer 8 uses materials such as non-woven fabric and nylon mesh to intercept large dust particles larger than 5μm, achieving a filtration efficiency of over 95%. The medium-efficiency filter layer 9 typically uses a bag-type structure, employing heat-sealing technology to prevent filter material deformation due to compression, achieving a filtration efficiency of approximately 65% for 1.0μm particles. The high-efficiency filter layer 10 uses polypropylene filter paper or glass fiber composite material, with a pore size as low as 0.1μm, achieving a filtration efficiency of 99.5% for fine particles such as PM2.5. Both sides of the exhaust gas treatment box 1 are equipped with doors 11; these doors can be opened to clean the filter layers.
[0025] A drive shaft 12 is installed through the top of the exhaust gas treatment box 1. The bottom of the drive shaft 12 is fixedly connected to the rotating column 6. A gear 13 is installed on the top of the drive shaft 12. Two limit seats 14 are symmetrically installed on the top of the exhaust gas treatment box 1. A moving column 15 is installed through the limit seat 14. A rack 16 is fixed on the moving column 15. The rack 16 meshes with the gear 13. Both the gear 13 and the rack 16 are galvanized to improve their service life.
[0026] A cylinder 17 is provided on one side of the limiting seat 14. The cylinder 17 is installed on the top of the exhaust gas treatment box 1. The output end of the cylinder 17 is fixedly connected to the moving column 15. Both ends of the exhaust gas treatment box 1 are provided with arc-shaped adjustment areas 3. One arc-shaped adjustment area 3 is connected to an air inlet pipe 4, and the other arc-shaped adjustment area 3 is connected to an air outlet pipe 5. Rotating columns 6 are provided on both sides of the partition seat 2. The rotating columns 6 are movably connected to the exhaust gas treatment box 1. A sealing plate 7 is fixed on one side of the rotating column 6. When the corresponding cylinder 17 is activated, the moving column 15 is moved. Under the transmission action of the rack 16 and the gear 13, the rotating column 6 will move the sealing plate 7.
[0027] The working principle of this utility model is as follows: When this waste gas treatment equipment is in use, the interior of the waste treatment box 1 can be divided into two independent chambers by setting the partition 2. One of the chambers is idle during normal use.
[0028] When it is necessary to clean the corresponding primary filter layer 8, medium-efficiency filter layer 9, and high-efficiency filter layer 10, the operator only needs to start the corresponding cylinder 17 to move the moving column 15. Under the transmission action of the rack 16 and gear 13, the rotating column 6 will drive the sealing plate 7 to move. Under the action of the two sealing plates 7, another idle chamber can be used (that is, the other chamber is connected to the air inlet pipe 4 and the air outlet pipe 5). At this time, the operator can open the box door 11 to clean or replace the corresponding filter layer without stopping the machine, which improves the efficiency of exhaust gas treatment.
[0029] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
