Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a process high-temperature waste gas emission treatment device. Background Technology

[0002] In the production processes of chemical, metallurgical, and building materials industries, a large amount of high-temperature waste gas is generated. This waste gas usually contains dust, harmful gases (such as sulfur dioxide, nitrogen oxides, volatile organic compounds, etc.) and a large amount of heat. If the high-temperature waste gas is directly discharged into the atmosphere, it will not only cause serious environmental pollution and endanger human health, but also fail to meet the requirements of energy conservation and environmental protection.

[0003] Existing waste gas collection and treatment devices cannot clean the dust and impurities in the device. The waste gas collection and treatment devices in mining plants are difficult to install and have high operating costs. However, the filter mechanism of the waste gas treatment device has poor disassembly function, which is not conducive to the later disassembly and cleaning of the filter mechanism, thus affecting the service life of the filter device.

[0004] Existing patent (publication number: CN220939743U) discloses a waste gas emission treatment device, relating to the technical field of waste gas emission devices. It includes a waste gas emission box, with a filter chamber fixedly installed inside. An air inlet pipe is fixedly installed on the top of the filter chamber, a spray chamber is fixedly installed on the right side of the filter chamber, a water tank is fixedly installed on the top of the spray chamber, and an exhaust pipe is fixedly installed on the right side of the spray chamber. An installation frame is fixedly installed at both ends inside the filter chamber, and a pushing mechanism is provided on the inner side of the installation frame. This utility model solves the problem of poor disassembly function of the filter mechanism in waste gas treatment devices, which hinders later disassembly and cleaning, thus affecting the service life of the filter device. It achieves the function of pushing and disassembling, facilitating convenient disassembly of the filter mechanism and increasing the service life of the filtration process.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing waste gas treatment devices typically lack a pre-cooling structure. When high-temperature waste gas directly enters the subsequent purification structure, it can easily damage the purification materials due to high temperatures, reducing purification efficiency and the lifespan of components. Furthermore, existing treatment devices have relatively simple purification processes, making it difficult to comprehensively remove multiple harmful components, thus hindering their usability.

[0006] Therefore, a high-temperature waste gas emission treatment device for processes is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 The present invention provides the following technical solution:

[0030] A process high-temperature exhaust gas emission treatment device includes a base 1, a pre-cooling mechanism 2 is provided on the left side of the top of the base 1, and a multi-stage purification mechanism 3 is provided on the right side of the top of the base 1.

[0031] The pre-cooling mechanism 2 includes a fixed frame 21. A serpentine heat exchange tube 22 is provided in the inner cavity of the fixed frame 21. The air inlet and outlet of the serpentine heat exchange tube 22 extend to both sides of the fixed frame 21, respectively. The side of the serpentine heat exchange tube 22 closest to the inner wall of the fixed frame 21 is fixedly connected to the inner wall of the fixed frame 21. Multiple heat dissipation fins 23 are fixedly connected to the surface of the serpentine heat exchange tube 22. A heat dissipation fan 24 is provided on the top of the serpentine heat exchange tube 22 and the heat dissipation fins 23. Support frames 25 are fixedly connected to the front and rear sides of the heat dissipation fan 24. The side of the support frame 25 closest to the fixed frame 21 is fixedly connected to the fixed frame 21.

[0032] In this embodiment: by setting up a base 1, a pre-cooling mechanism 2, and a multi-stage purification mechanism 3, the base 1 provides a supporting foundation for the pre-cooling mechanism 2 and the multi-stage purification mechanism 3. The pre-cooling mechanism 2 can quickly reduce the temperature of the high-temperature exhaust gas, preventing damage to subsequent purification components and extending the service life of the core purification components of the overall device. At the same time, it creates suitable working conditions for subsequent purification processes, improving the stability and efficiency of subsequent purification treatment. The multi-stage purification mechanism 3 can perform multi-stage comprehensive and deep purification treatment on the pre-cooled exhaust gas, gradually removing different types of pollutants such as dust and harmful gases from the exhaust gas. The purification coverage is wider, the purification effect is more thorough, and it ensures that the treated exhaust gas can meet the emission standards.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the multi-stage purification mechanism 3 includes a spray box 31, which is fixedly connected to the right side of the top of the base 1. The left side of the spray box 31 is connected to a pre-filter box 32 through a pipe, and the right side of the spray box 31 is connected to a deep purification box 33 through a pipe. A spray pipe 34 is provided at the top of the inner cavity of the spray box 31. The front side of the spray pipe 34 extends to the front side of the spray box 31. The side of the spray pipe 34 near the inner wall of the spray box 31 is fixedly connected to the inner wall of the spray box 31. Multiple atomizing nozzles 35 are connected to the bottom of the spray pipe 34.

[0034] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a connecting pipe 36 is connected to the left side of the pre-filter box 32, and the other end of the connecting pipe 36 is connected to the outlet end of the serpentine heat exchange tube 22. A filter screen plate 37 is snapped into the inner cavity of the pre-filter box 32.

[0035] Specifically, such as Figure 4 As shown, an ultraviolet lamp 38 is fixedly installed on the top left side of the inner cavity of the deep purification box 33, and an activated carbon filter element 39 is snapped into the right side of the inner cavity of the deep purification box 33.

[0036] In this embodiment: by setting up a spray box 31, a pre-filter box 32, a deep purification box 33, a spray pipe 34, an atomizing nozzle 35, a connecting pipe 36, a filter screen 37, an ultraviolet lamp 38, and an activated carbon filter element 39, during use, the cooled exhaust gas is transported to the pre-filter box 32 through the outlet end of the serpentine heat exchange pipe 22 and the connecting pipe 36. The filter screen 37 in the pre-filter box 32 performs preliminary filtration on the exhaust gas, removing most of the dust and other solid impurities to prevent clogging of subsequent purification components. The filtered exhaust gas enters the spray box 31 through the pipe, where it is further purified externally. After the liquid is delivered to the spray pipe 34, it is evenly atomized and sprayed through multiple atomizing nozzles 35 at the bottom of the spray pipe 34, making full contact and mixing with the exhaust gas, and efficiently removing harmful gases such as sulfur dioxide from the exhaust gas. The exhaust gas that has completed the spray purification continues to enter the deep purification box 33 through the pipeline. The ultraviolet lamp tube 38 on the top left side of the deep purification box 33 is turned on, emitting ultraviolet light to degrade volatile organic compounds and other harmful components in the exhaust gas. Subsequently, the exhaust gas passes through the activated carbon filter element 39 on the right side, which further adsorbs residual harmful impurities and odors, thereby achieving multi-stage comprehensive deep purification treatment of the exhaust gas.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, support legs 4 are fixedly connected to the four corners of the bottom of the fixed frame 21, and the bottom of the support legs 4 is fixedly connected to the top of the base 1.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, the inlet end of the serpentine heat exchange tube 22 is connected to the inlet pipe 5, and the left side of the surface of the inlet pipe 5 is fixedly connected to the first connecting flange 6.

[0039] In this embodiment: the support leg 4 can support and fix the fixed frame 21, and the air inlet pipe 5 and the first connecting flange 6 can be bolted to the exhaust gas source pipeline for a stable connection.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the top of the spray box 31 is bolted with a first maintenance sealing cover 7, and the tops of the pre-filtration box 32 and the deep purification box 33 are both bolted with a second maintenance sealing cover 8.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, an exhaust pipe 9 is connected to the right side of the deep purification chamber 33, and a second connecting flange 10 is fixedly connected to the right side of the surface of the exhaust pipe 9.

[0042] In this embodiment: by providing a detachable first maintenance sealing cover 7, it is convenient to perform maintenance work on the spray pipe 34 and atomizing nozzle 35 in the spray box 31. By providing a detachable second maintenance sealing cover 8, it is convenient to perform maintenance or replacement on the filter screen 37, ultraviolet lamp tube 38 and activated carbon filter element 39 in the pre-filtration box 32 and the deep purification box 33.

[0043] Specifically, such as Figure 5 As shown, a drain pipe 11 is connected to the bottom right side of the spray box 31, and a valve 12 is installed inside the drain pipe 11.

[0044] Specifically, such as Figure 4 , Figure 5 As shown, a guide block 13 is provided at the bottom of the inner cavity of the spray box 31, and the side of the guide block 13 near the inner wall of the spray box 31 is fixedly connected to the inner wall of the spray box 31.

[0045] In this embodiment: by setting up a drain pipe 11 and a valve 12, in order to facilitate the discharge of sprayed water from the spray box 31, a guide block 13 is set up to guide the sprayed water to the drain pipe 11.

[0046] Working Principle: During operation, the first connecting flange 6 on the inlet pipe 5 can be securely connected to the exhaust pipe of the waste gas source using bolts. High-temperature waste gas generated during industrial production then enters the serpentine heat exchanger tube 22 through the inlet pipe 5. The evenly distributed heat dissipation fins 23 on the surface of the serpentine heat exchanger tube 22 increase the heat exchange area. Simultaneously, the cooling fan 24 is activated to force airflow onto the serpentine heat exchanger tube 22 and the heat dissipation fins 23, rapidly reducing the temperature of the high-temperature waste gas inside the serpentine heat exchanger tube 22. The cooled waste gas is then transported through the outlet of the serpentine heat exchanger tube 22 to the pre-filter box 32 via the connecting pipe 36. The filter screen 37 in the pre-filter box 32 performs preliminary filtration of the waste gas, removing most of the dust and other solid impurities to prevent clogging of subsequent purification components. The filtered waste gas then enters the spray box through a pipeline. 31. At this point, after the external purification liquid is delivered to the spray pipe 34, it is evenly atomized and sprayed by multiple atomizing nozzles 35 at the bottom of the spray pipe 34, fully contacting and mixing with the exhaust gas, effectively removing harmful gases such as sulfur dioxide from the exhaust gas. The exhaust gas that has completed the spray purification continues to enter the deep purification box 33 through the pipeline. The ultraviolet lamp tube 38 on the top left side of the deep purification box 33 is turned on, emitting ultraviolet light to degrade volatile organic compounds and other harmful components in the exhaust gas. Subsequently, the exhaust gas passes through the activated carbon filter element 39 on the right side, which further adsorbs residual harmful impurities and odors, thereby achieving multi-stage comprehensive deep purification treatment of the exhaust gas. Finally, the purified exhaust gas is discharged through the exhaust pipe 9 on the right side of the deep purification box 33. The second connecting flange 10 on the exhaust pipe 9 can be easily connected to the external discharge pipeline by bolts.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
