Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] The filtering structure 2 includes front splicing flange 201 and rear splicing flange 202, the front splicing flange 201 and rear splicing flange 202 are welded with connecting strip 203, the adjacent connecting strip 203 is fixedly installed with sealing plate, and the front splicing flange 201, connecting strip 203, sealing plate and rear splicing flange 202 jointly form the placement cavity, and the inside of placement cavity is provided with filter screen 204, silver ion sterilization layer 205, first DPF layer 206 and second DPF layer 207.

[0025] Specifically, the front side of sealing communication pipe 102 is fixedly installed with connecting flange 105, and the closed valve body 101 is connected with the sealing communication pipe 102 through the connecting flange 105.

[0026] In this embodiment, the connecting flange 105 is used to ensure the stable connection between the closed valve body 101 and the sealing communication pipe 102. At the same time, the design of the connecting flange 105 facilitates disassembly and assembly, making the maintenance and replacement of the entire sealing structure more convenient.

[0027] In addition, the material selection of the connecting flange 105 is also crucial, which needs to have good corrosion resistance and sealing performance to ensure its long-term stable operation in harsh working conditions.

[0028] Specifically, the back side of the sealing communication pipe 102 is provided with a sealing gasket 106, and the sealing communication pipe 102 and the front splicing flange 201 are connected through the sealing gasket 106.

[0029] In this embodiment, the sealing gasket 106 is made of a high-temperature-resistant and corrosion-resistant elastic material, which can ensure the sealing effect and adapt to different temperature environments, improving the stability and durability of the equipment.

[0030] In actual application, the service life of the sealing structure can be effectively prolonged and the overall performance of the equipment can be improved by regular inspection and replacement of the sealing gasket 106.

[0031] Specifically, the filter screen 204, the silver ion sterilization layer 205, the first DPF layer 206 and the second DPF layer 207 are arranged in front of each other, and the intervals between the filter screen 204, the silver ion sterilization layer 205, the first DPF layer 206 and the second DPF layer 207 are the same.

[0032] In this embodiment, the filter screen 204 is made of stainless steel, which has good corrosion resistance and filtering effect, and can effectively block large particle impurities in the tail gas, protecting the silver ion sterilization layer 205 and the first DPF layer 206 and the second DPF layer 207 from being damaged;

[0033] In addition, the silver ion sterilization layer 205 has strong sterilization and disinfection function by releasing silver ions, which can effectively kill harmful bacteria and viruses in the tail gas, improving the hygiene and safety of the tail gas treatment;

[0034] And the first DPF layer 206 and the second DPF layer 207 are both made of high-efficiency particulate collection material, which has excellent trapping efficiency and regeneration performance, and can maintain high-efficiency tail gas purification effect for a long time.

[0035] Specifically, the adsorption structure 3 includes a DPF ceramic carrier pipe 301, the inner side of the DPF ceramic carrier pipe 301 is provided with a DPF ceramic carrier, and the top end and the bottom end of the DPF ceramic carrier pipe 301 are respectively fixedly connected with a connecting pipe 302 and a discharge pipe 303.

[0036] In the embodiment, the DPF ceramic carrier tube 301 is made of high-strength and high-heat-resistant ceramic material, which can withstand the impact and pressure of high-temperature exhaust gas and ensure the long-term stable operation of the device.

[0037] The DPF ceramic carrier has a plurality of parallel holes on the surface, which facilitates the removal of soot on the filter wall of the DPF.

[0038] Specifically, the DPF ceramic carrier tube 301 is provided with a pressure gauge 304 and a pressure relief pipe 305 on the outside, and the pressure gauge 304 and the pressure relief pipe 305 are located on both sides of the DPF ceramic carrier tube 301.

[0039] In the embodiment, the pressure gauge 304 can display the pressure inside the DPF ceramic carrier tube 301 in real time, so that the operator can know the working state of the device in time and prevent the device from being damaged or the performance from being reduced due to excessive pressure.

[0040] The pressure relief pipe 305 can perform pressure relief operation in time when the internal pressure of the device is abnormal, ensuring the safe operation of the device.

[0041] In actual application, the operator can observe the reading of the pressure gauge 304 and use the pressure relief pipe 305 to control and maintain the device more accurately and effectively, thereby improving the overall performance and reliability of the device.

[0042] In use, the operator first starts the external driving source 104, and the movable end of the external driving source 104 drives the valve 103 to rotate in the closed valve body 101, thereby controlling the opening and closing of the sealed communication pipe 102. When the valve 103 is opened, the exhaust gas enters the filter structure 2 through the sealed communication pipe 102.

[0043] The exhaust gas first passes through the filter screen 204, which blocks the large-particle impurities in the exhaust gas outside, protecting the subsequent filter layer from being damaged. Then, the exhaust gas enters the silver ion sterilization layer 205, which releases silver ions to kill harmful bacteria and viruses in the exhaust gas, improving the hygiene and safety of exhaust gas treatment. Next, the exhaust gas passes through the first DPF layer 206 and the second DPF layer 207 in turn, both of which are made of high-efficiency particulate trapping material, which can trap tiny particles in the exhaust gas and ensure that the exhaust gas emission meets environmental protection standards.

[0044] The tail gas treated by the filtering structure 2 enters the adsorbing structure 3. The tail gas flows in the DPF ceramic carrier pipe 301 and is fully contacted with the DPF ceramic carrier, and the harmful substances in the tail gas are adsorbed on the DPF ceramic carrier. At the same time, the operator can know the pressure condition inside the DPF ceramic carrier pipe 301 by observing the reading of the pressure gauge 304, so as to prevent the equipment damage or performance decline caused by the excessively high pressure. When the internal pressure of the equipment is abnormal, the operator can perform the pressure relief operation in time through the pressure relief pipe 305, so as to ensure the safe operation of the equipment.

[0045] In summary, the DPF packaging leakproof dismounting sealing structure has the advantages that the sealing structure is provided with the dismounting sealing structure 1, so that the sealing structure has better dismounting convenience in use, thereby facilitating the subsequent maintenance and replacement of the filtering structure 2 and the adsorbing structure 3, and ensuring that the filtering structure 2 and the adsorbing structure 3 can be effectively sealed after installation, preventing the diesel or other fluids from leaking during the purification process, improving the safety and reliability of the equipment, helping to keep the equipment clean, preventing the pollutants from entering the system, and prolonging the service life of the equipment.
