Description

Technical Field

[0001] This utility model relates to the field of semi-coke production technology, specifically to a VOCs catalytic combustion removal device in the semi-coke production process. Background Technology

[0002] Semi-coke is produced by burning high-quality Jurassic coal blocks abundant in the Shenfu Coalfield (Shenmu + Fugu). As a more environmentally friendly new material, it has the characteristics of high fixed carbon content, high resistivity, high chemical activity, low ash content, low aluminum content, low sulfur content, and low phosphorus content. The production process of semi-coke requires a drying system to dry the coal, using high-temperature flue gas generated by coal gas as fuel as the drying heat source.

[0003] During the drying process of semi-coke, organic compounds are generated due to high temperatures. Most of these organic compounds flow with the hot gas, so a removal device is needed to burn them. However, existing devices require the separation of particulate matter, moisture, and other impurities from the flue gas before filtration and combustion. After filtering particulate matter and moisture, the existing devices cannot store the impurities separately. The presence of moisture causes the impurities to mix together, which not only affects the filtration effect but also the subsequent processing of the impurities.

[0004] Meanwhile, in some existing devices, the filter plate is simply clipped inside the housing, leaving a large gap between the filter plate and the housing. This allows some flue gas to easily escape through the gap, affecting the filter plate's filtration efficiency and making subsequent flue gas treatment inconvenient, thus reducing the applicability of the device. Utility Model Content

[0005] The purpose of this invention is to provide a VOCs catalytic combustion removal device in the production process of semi-coke, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a VOCs catalytic combustion removal device for semi-coke production, comprising a mounting shell and a catalytic mechanism mounted on one side thereof, and further comprising:

[0007] A mounting bracket is fixed to the inner cavity of the mounting shell. A positioning mechanism is installed inside the mounting bracket. A filter plate is slidably connected to the inner cavity of the mounting bracket. A drain hole is opened at the bottom of the inner cavity of the mounting bracket. A dirt collection shell is embedded at the bottom of the inner cavity of the mounting shell.

[0008] A drain valve is installed at the bottom of the inner cavity of the sludge collection shell. A movable mechanism is installed in the inner cavity of the housing. Cleaning plates are installed on both sides of the surface of the movable mechanism. A push plate is fixedly connected to the surface of one cleaning plate, and a tension spring is fixedly connected to the surface of the other cleaning plate.

[0009] Preferably, the positioning mechanism includes a compression spring fixed to the inner cavity of the mounting bracket and a positioning frame fixed to its other end, wherein a movable rod is fixedly connected to the surface of the positioning frame.

[0010] Preferably, the movable mechanism includes a fixed frame fixed to the inner wall of the mounting housing and a spur gear rotating on one side thereon, with rack plates meshing above and below the surface of the spur gear.

[0011] Preferably, a guide block is fixedly connected to the surface of the positioning frame, and a guide groove is provided in the inner cavity of the mounting frame, with the inner wall of the guide groove slidably connected to the surface of the guide block.

[0012] Preferably, one side of the positioning frame has an inclined structure design, and the positioning frame is used in conjunction with the mounting frame.

[0013] Preferably, the mounting frame has a U-shaped cross-sectional design, and the filter plate is used in conjunction with the mounting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a collection shell to store each type of impurity separately, reducing the likelihood of impurities mixing together. Furthermore, the combination of the pushing plate, the movable mechanism, and the tension spring allows the cleaning plate to scrape the impurities inside the collection shell, facilitating their removal. This not only improves the filtration effect but also makes impurity processing easier. Simultaneously, the positioning mechanism and mounting bracket reduce gaps between the filter plate and the mounting bracket and positioning mechanism, minimizing flue gas escape and further enhancing the filtration effect. This solves the problems of existing devices being inconvenient for impurity processing and having poor applicability. Attached Figure Description

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-4As shown, a VOCs catalytic combustion removal device in the production of semi-coke includes a mounting shell 1. A catalytic mechanism 2 is installed on one side of the mounting shell 1. Under the action of the catalytic mechanism 2, the flue gas can be filtered through activated carbon, and then the organic compounds on the surface of the activated carbon are burned by heating, thereby decomposing the organic compounds into carbon dioxide and water vapor, thus treating the organic compounds. A mounting frame 3 is fixedly connected to the inner cavity of the mounting shell 1. There are three mounting frames 3. A positioning mechanism 4 is installed inside the mounting frame 3. A filter plate 5 is slidably connected to the inner cavity of the mounting frame 3. The cross-sectional shape of the mounting frame 3 is U-shaped. The design incorporates filter plate 5 and mounting bracket 3. The filter plate 5 is conveniently positioned using its shape, ensuring greater stability. The filter plates 5 installed inside the three mounting brackets 3 are made of different materials, effectively filtering particulate matter, moisture, and other impurities from the flue gas. The positioning mechanism 4 ensures that the filter plate 5 fits snugly against the interior of the mounting bracket 3 during replacement, minimizing flue gas escape from gaps and effectively improving the filtration efficiency. The bottom of the inner cavity of the mounting bracket 3 has an opening... The drain hole 6 and the bottom of the inner cavity of the mounting shell 1 are both embedded with a sludge collection shell 7. Under this action, particulate matter, moisture and other impurities on the surface of the filter plate 5 can be discharged into the interior of the sludge collection shell 7 through the drain hole 6 or the surface of the filter plate 5. This allows for the separate storage of different foreign objects, preventing them from mixing and affecting subsequent processing. A drain valve 8 is installed at the bottom of the inner cavity of the sludge collection shell 7, which facilitates the discharge of foreign objects from inside the sludge collection shell 7, making it convenient for staff to process them. The inner cavity of the mounting shell 1 is equipped with a movable mechanism 9, and cleaning devices are installed on both sides of the surface of the movable mechanism 9. The cleaning plate 11 has a surface that is slidably connected to the inner wall of the sludge collection shell 7. A push plate 10 is fixedly connected to the surface of one side of the cleaning plate 11, and a tension spring 12 is fixedly connected to the surface of the other side of the cleaning plate 11. The other end of the tension spring 12 is used in conjunction with the movable mechanism 9. Under this action, when the filter plate 5 is installed, when the filter plate 5 no longer presses the push plate 10, it drives the two cleaning plates 11 to move through the cooperation of the movable mechanism 9. This allows the cleaning plates 11 to bring the foreign objects inside the sludge collection shell 7 closer to the drain valve 8, thereby facilitating the discharge of foreign objects inside the sludge collection shell 7 and reducing the residue of foreign objects inside the sludge collection shell 7.

[0023] The positioning mechanism 4 includes a compression spring 41 fixed to the inner cavity of the mounting frame 3. The other end of the compression spring 41 is fixedly connected to a positioning frame 42. A movable rod 43 is fixedly connected to the surface of the positioning frame 42. The other end of the movable rod 43 penetrates into the interior of the mounting frame 3 and slides along the inner wall of its penetration point. Under this action, the positioning frame 42, in conjunction with the compression spring 41, presses against the surface of the filter plate 5, thereby causing the inner wall of the mounting frame 3 to fit against the surface of the filter plate 5, and thus the surface of the positioning frame 42 to fit against the surface of the filter plate 5. This reduces gaps on the surface of the filter plate 5 and effectively improves the filtration effect of the filter plate 5 on flue gas. A guide block 13 is fixedly connected to the surface of the positioning frame 42. The inner cavity of the mounting frame 3 is provided with a guide groove 14. The inner wall of the guide groove 14 is slidably connected to the surface of the guide block 13. Under this action, the moving positioning frame 42 can be guided by the cooperation of the guide block 13 and the guide groove 14, so that the positioning frame 42 can be more stable when moving, and avoid the positioning frame 42 being unstable when moving, which would affect the limiting effect on the filter plate 5. One side of the positioning frame 42 is designed with an inclined structure. The positioning frame 42 is used in conjunction with the mounting frame 3. Under this action, the shape of the positioning frame 42 can guide the filter plate 5 when it is embedded in the interior of the mounting frame 3, so that the filter plate 5 is more convenient to move into the interior of the mounting frame 3.

[0024] The active mechanism 9 includes a fixed frame 91 fixed to the inner wall of the mounting shell 1. A spur gear 92 is rotatably connected to one side of the fixed frame 91. A rack plate 93 meshes with the upper and lower surfaces of the spur gear 92. One side of the rack plate 93 is fixedly connected to the surface of the cleaning plate 11. Under this action, the cleaning plate 11 can move when the filter plate 5 no longer squeezes the pushing plate 10. The spur gear 92 and the rack plate 93 cooperate with each other to enable the cleaning plate 11 to push the foreign objects inside the dirt collection shell 7 to a place close to the drain valve 8, so as to facilitate the discharge of foreign objects through the drain valve 8.

[0025] It is worth noting that the technical features such as the filter plate 5 and the catalytic mechanism 2 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0026] Working principle: First, the flue gas is introduced into the installation shell 1. Under the action of the filter plate 5, particulate matter, moisture and other impurities in the flue gas are initially filtered. When there are many foreign objects on the surface of the filter plate 5, the foreign objects will fall into the dirt collection shell 7 under their own weight. When the filter plate 5 needs to be replaced, the installation shell 1 is opened, and then the push plate 10 is pushed outward by the tension spring 12, making it easy for the operator to remove the filter plate 5. After the operator removes the filter plate 5, it no longer comes into contact with the push plate 10. Under the action of the tension spring 12, it can cooperate with the rack plate 93 to clean the filter plate. The filter plate 11 can push foreign objects inside the sludge collection shell 7 towards the drain valve 8. Then, the operator opens the drain valve 8 to discharge the foreign objects inside the sludge collection shell 7. This is not only convenient, but also allows for separate storage of foreign objects, reducing the possibility of them mixing and affecting subsequent processing. Subsequently, the filter plate 5 is embedded inside the mounting frame 3. With the cooperation of the compression spring 41 and the positioning frame 42, the filter plate 5 can be made to fit the surfaces of the mounting frame 3 and the positioning frame 42, thereby making the filter plate 5 more stable and reducing the gap between the filter plate 5 and the mounting frame 3 and the positioning frame 42, effectively improving the filtration effect of the filter plate 5 on the flue gas.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
