Description

Technical Field

[0001] This utility model relates to the technical field of solid waste gas treatment devices, and particularly to solid waste gas treatment devices based on bag filter dust collection. Background Technology

[0002] With increasingly stringent environmental policies in place, solid waste treatment has become a crucial aspect of environmental protection. During the storage and decomposition of solid waste, large amounts of mixed gases containing dust and harmful gases (such as hydrogen sulfide, ammonia, and volatile organic compounds) are released. If these gases are discharged directly without effective treatment, they will cause serious harm to the atmospheric environment and human health.

[0003] Traditional solid waste gas treatment devices mostly employ single adsorption or filtration technologies, such as simple baghouse dust collectors. These devices use fabric bags to intercept particulate matter in the gas, but they can only handle solid impurities such as dust and cannot effectively deal with harmful gases with complex compositions. On the other hand, the bags are prone to clogging or damage in high-temperature and high-humidity environments, leading to a sharp decline in treatment efficiency, and frequent bag replacements increase operation and maintenance costs. Utility Model Content

[0027] Reference Figure 1 , Figure 2 and Figure 3As shown, the solid waste gas treatment device based on bag filter dust collection includes a treatment chamber 1 and an adsorption assembly 4. The treatment chamber 1 includes a chamber shell 11 and a sealing cover 12. The sealing cover 12 is installed on the front end of the chamber shell 11 and is sealed and fixedly connected to the chamber shell 11. An exhaust shell 2 is provided at the head of the chamber shell 11. The exhaust shell 2 is integrally formed with the chamber shell 11, and several sets of pre-cooling assemblies 3 are fixedly installed in the exhaust shell 2. A refrigeration mechanism 5 that cooperates with the pre-cooling assembly 3 is also installed on the outer side of the sealing cover 12. The refrigeration mechanism 5 is fixedly connected to the sealing cover 12. One end of the adsorption assembly 4 is connected to the exhaust shell 2. The sealed design of the treatment chamber 1 ensures the airtightness of the solid waste gas treatment process, prevents harmful gases from leaking into the surrounding environment, and ensures the safety of operators and the cleanliness of the environment. The integral formation of the exhaust shell 2 with the chamber shell 11 enhances the overall structural strength of the device, making it more stable and durable. The pre-cooling assembly 3 can initially cool the high-temperature gas generated by solid waste, reducing the difficulty and cost of subsequent treatment. The refrigeration unit 5, in conjunction with the pre-cooling component 3, can more effectively control the gas temperature and improve the treatment effect. The adsorption component 4 extracts the treated gas for further processing or discharge. A dispensing shell 111 is installed on the upper surface of the housing 11, and the dispensing shell 111 is sealed and fixedly connected to the housing 11. A flip-openable cover component 112 is installed on the upper surface of the dispensing shell 111. The sealed and fixed connection between the dispensing shell 111 and the housing 11 ensures no gas leakage when dispensing solid waste. The flip-openable cover component 112 facilitates the dispensing of solid waste by operators and maintains good sealing when closed, keeping the environment inside the treatment tank 1 stable.

[0028] Reference Figure 2 and Figure 3 As shown, the exhaust housing 2 includes a main housing 21 and a filter plate 22. A clamping seat 211 is provided on the main housing 21, and the clamping seat 211 is integrally formed with the main housing 21. The filter plate 22 is inserted and installed in the clamping seat 211. The filter plate 22 in the exhaust housing 2 can perform preliminary filtration of the gas, intercepting larger dust particles and preventing these particles from entering subsequent processing stages, reducing wear and clogging of the equipment, and extending the service life of the equipment. The design of the clamping seat 211 facilitates the installation and removal of the filter plate 22, and makes it easy to clean and replace it regularly.

[0029] Reference Figure 2 and Figure 3As shown, the precooling assembly 3 includes an X-shaped mesh plate 31, a heat-conducting central tube 32, and a support plate 33. The heat-conducting central tube 32 is fixedly installed in the middle of the X-shaped mesh plate 31, and the support plate 33 is symmetrically installed on both sides of the heat-conducting central tube 32, with both ends of the support plate 33 fixed to the X-shaped mesh plate 31 and the heat-conducting central tube 32, respectively. The design of the X-shaped mesh plate 31 in the precooling assembly 3 increases the contact area between the gas and the precooling assembly 3, allowing the gas to exchange heat more fully with the precooling assembly 3 and improving the precooling efficiency. The heat-conducting central tube 32 can quickly conduct heat away, while the support plate 33 ensures the structural stability of the entire precooling assembly 3.

[0030] Reference Figure 1 As shown, the adsorption assembly 4 includes a vacuum pump 41, an exhaust pipe 42, and a connector 43. One end of the exhaust pipe 42 is connected to the air inlet of the vacuum pump 41, and the connector 43 is sealed to the other end of the exhaust pipe 42. The vacuum pump 41 of the adsorption assembly 4 provides power to extract gas from the treatment chamber 1. The exhaust pipe 42 guides the gas to a designated location, and the sealed connection of the connector 43 ensures that the gas does not leak during transmission, guaranteeing the continuity and effectiveness of gas treatment.

[0031] Reference Figure 4 , Figure 5 and Figure 6 As shown, the refrigeration mechanism 5 includes a heat-conducting outer plate 51, a cooling fan 52, and an inner insertion tube 53 connected to the heat-conducting middle tube 32. The heat-conducting outer plate 51 is fixedly installed on the outer surface of the sealing cover 12, the cooling fan 52 is fixedly installed on the outer surface of the heat-conducting outer plate 51, one end of the inner insertion tube 53 is fixedly installed on the inner surface of the heat-conducting outer plate 51, and the other end of the inner insertion tube 53 is inserted and fixed in the heat-conducting middle tube 32. The heat-conducting outer plate 51 of the refrigeration mechanism 5 can quickly dissipate heat, and the cooling fan 52 further enhances the heat dissipation effect. The inner insertion tube 53 is connected to the heat-conducting middle tube 32, which can transfer the cooling effect to the pre-cooling component 3 to achieve effective cooling of the gas. The heat-conducting outer plate 51 includes a large metal plate 511, a heat dissipation bend 512, and an inclined plate 513 for installing the inner insertion tube 53. The heat dissipation bend 512 is fixedly installed on the large metal plate 511, and the inclined plate 513 is fixedly installed on one side of the large metal plate 511. The outer heat-conducting plate 51 has a large metal plate 511 with good thermal conductivity, and the heat dissipation bend 512 increases the heat dissipation area and improves heat dissipation efficiency. The design of the inclined plate 513 facilitates the installation of the inner tube 53 and makes the connection between the refrigeration mechanism 5 and the pre-cooling component 3 more stable.

[0032] In this embodiment, during actual use, the flip-top assembly 112 is opened, and solid waste is placed into the processing tank 1 through the loading shell 111. The flip-top assembly 112 is closed, and the suction pump 41 is started to extract the gas from the processing tank 1. When the gas passes through the exhaust shell 2, it is initially filtered by the filter screen 22 to remove larger dust particles. At the same time, the cooling mechanism 5 is started, and the cooling fan 52 runs to dissipate the heat from the heat-conducting outer plate 51. The inner tube 53 is inserted to transfer the cooling effect to the heat-conducting middle tube 32 to cool the pre-cooling assembly 3. When the gas passes through the pre-cooling assembly 3, it comes into full contact with the X-shaped mesh plate 31, undergoes heat exchange, and its temperature is reduced. The gas that has been pre-cooled and filtered is extracted through the exhaust pipe 42 for further processing or discharge.

[0033] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
