Specific implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1

[0041] Such as Figures 1 to 8As shown in the figure, the present invention provides a high-temperature waste gas catalytic device, including a box body 1; an exhaust gas pipeline 2 is arranged at the top inside the box body 1; two adsorption plate assemblies 3 are provided, and the two adsorption plate assemblies 3 are symmetrically arranged on both sides of the exhaust gas pipeline 2 respectively. Two air grooves 21 corresponding to the adsorption plate assemblies 3 one by one are arranged on the side wall of the exhaust gas pipeline 2; a filter box assembly 4 is arranged at the bottom inside the box body 1; a plurality of intake pipes 5 are provided, and the plurality of intake pipes 5 are arranged on the outer wall of the bottom of the box body 1; the adsorption plate assembly 3 includes a base 31 inclined on the side wall of the exhaust gas pipeline 2, and two plate grooves 311 are arranged on the base 31. The two plate grooves 311 correspond to the two adsorption plate assemblies 3 one by one. A plurality of adsorption plates 32 are movably arranged in the plate grooves 311 from top to bottom in sequence. A pushing cylinder 33 is embedded in the side wall of the exhaust gas pipeline 2, and the piston rod of the pushing cylinder 33 is in contact with the lowermost adsorption plate 32. An out-plate groove 34 corresponding to the position of the lowermost adsorption plate 32 is arranged on the side wall of the box body 1; the filter box assembly 4 includes a rotating motor 41 embedded in the inner wall of the box body 1, a filter outer box 42 is arranged on the output shaft of the rotating motor 41, a grid groove group 43 is arranged inside the filter outer box 42, and a filter rod group 44 with a shape adapted to the grid groove group 43 is movably inserted in the grid groove group 43; the exhaust gas pipeline 2 is vertically arranged at the top inside the box body 1, and the upper end of the exhaust gas pipeline 2 penetrates through the top of the box body 1.

[0042] The waste gas enters the bottom of the box body 1 through the intake pipe 5 and is first filtered and adsorbed by the filter box assembly 4 (that is, the waste gas enters the filter rod group 44 in the grid groove group 43 to filter and adsorb the fine particle impurities in the organic waste gas); the waste gas after being filtered and adsorbed by the filter box assembly 4 enters the two adsorption plate assemblies 3 on the side wall of the exhaust gas pipeline 2 for further filtering and adsorption (that is, the waste gas passes through the plate groove 311 on the base 31 and enters the lowermost adsorption plate 32 for filtering); and then it enters the exhaust gas pipeline 2 through the air groove 21 and is discharged.

[0043] When the lowermost adsorption plate 32 has been used for a long time and there are more fine particle impurities adhered to it, the pushing cylinder 33 can be started to push out the lowermost adsorption plate 32, so as to continue to use other adsorption plates 32 in sequence to adsorb the fine particle impurities in the organic waste gas.

[0044] The rotating motor 41 can drive the filter outer box 42 to rotate, so that the grid groove group 43 faces the side wall of the box body 1, which is convenient for taking out or installing the filter rod group 44 from the grid groove group 43.

[0045] Embodiment 2

[0046] On the basis of Embodiment 1, as Figure 1 、 Figures 3 to 5As shown in the figure, the adsorption plate 32 includes an activated carbon adsorption bottom plate 321, and the activated carbon adsorption bottom plate 321 is movably arranged in the plate groove 311; an upper baffle plate 322 is arranged on the top surface of the activated carbon adsorption bottom plate 321; a clamping rod 324 is arranged on the top surface of the upper baffle plate 322, and the piston rod of the pushing cylinder 33 abuts against the clamping rod 324 on the lowermost adsorption plate 32; a clamping rod groove 323 is arranged on the bottom surface of the activated carbon adsorption bottom plate 321, and the size and shape of the clamping rod groove 323 are adapted to those of the clamping rod 324, which is convenient for the activated carbon adsorption bottom plate 321 to adsorb waste gas; the sum of the heights of the activated carbon adsorption bottom plate 321, the upper baffle plate 322 and the clamping rod 324 is adapted to the height of the plate outlet groove 34.

[0047] Before the high-temperature waste gas catalytic device is used, multiple adsorption plates 32 can be stacked in sequence from top to bottom (that is, the clamping rod groove 323 in the adsorption plate 32 located in the upper layer is stuck outside the clamping rod 324 in the adsorption plate 32 located in the lower layer, which is beneficial to make the stacked multiple adsorption plates 32 firmly placed); and the lowermost adsorption plate 32 is located in the plate groove 311 (the size and shape of the plate groove 311 are adapted to those of the activated carbon adsorption bottom plate 321, so that the activated carbon adsorption bottom plate 321 can be placed in the plate groove 311 without falling off and is convenient for waste gas to pass through the activated carbon adsorption bottom plate 321).

[0048] When the lowermost adsorption plate 32 is used for a long time and there are many fine particle impurities adhered to it, the pushing cylinder 33 can be started to push the lowermost adsorption plate 32 (the end far from the pushing cylinder 33) out of the plate outlet groove 34 to the outside of the box body 1 (the clamping rod 324 in the lowermost adsorption plate 32 can slide in the clamping rod groove 323 in the penultimate adsorption plate 32), and then the adsorption plate 32 is pulled out. The penultimate adsorption plate 32 can fall into the plate groove 311, so as to continue to use other adsorption plates 32 in sequence to adsorb the fine particle impurities in the organic waste gas until all the stacked multiple adsorption plates 32 are used up.

[0049] The height of the plate groove 311 can be made to be adapted to the number of stacked adsorption plates 32, and the size of the plate groove 311 is adapted to that of the adsorption plate 32, which is convenient for the pushing cylinder 33 to push the lowermost adsorption plate 32 out of the plate outlet groove 34 without affecting the positions of other adsorption plates 32, so that it is convenient for other adsorption plates 32 to fall into the plate groove 311 in sequence for continuous use.

[0050] A support plate can be inclinedly arranged on the outer side wall of the box body 1 below the plate groove 311, which is convenient for the support plate to play a supporting role for the adsorption plate 32 when the adsorption plate 32 needs to be removed from the box body 1.

[0051] The side wall of the activated carbon adsorption bottom plate 321 close to the exhaust gas pipeline 2 is a sieve-like structure, and the other three side walls are all solid plate-like structures, which is conducive to enabling the exhaust gas to enter the exhaust gas pipeline 2 after being filtered by the activated carbon adsorption bottom plate 321, and avoiding emission during the adsorption and filtration of the exhaust gas.

[0052] Embodiment Three

[0053] On the basis of Embodiment One, as Figure 1 、 Figures 6 to 9 shown, both the top surface and the bottom surface of the filtering outer box 42 are open. The grid groove group 43 includes a plurality of rectangular grooves 431 distributed in a matrix. The two ends of the rectangular groove 431 in the length direction are flush with the top opening of the filtering outer box 42 and the bottom opening of the filtering outer box 42 respectively; the filtering rod group 44 includes a rod seat plate 441, and the rod seat plate 441 is movably arranged on the top opening of the filtering outer box 42; a plurality of filtering rods 442 are provided, and the plurality of filtering rods 442 are distributed in a matrix on the rod seat plate 441. The number of the filtering rods 442 is the same as the number of the rectangular grooves 431, and the filtering rods 442 correspond to the rectangular grooves 431 one by one. The filtering rods 442 are respectively movably inserted into the corresponding rectangular grooves 431; both the filtering rods 442 and the rod seat plate 441 are honeycomb-like structures; when the exhaust gas enters the box body 1 through the air inlet pipe 5 and then enters from below the rectangular grooves 431 and is filtered by the filtering rods 442 in the rectangular grooves 431 (the rectangular grooves 431 distributed in a matrix are conducive to evenly distributing the exhaust gas and increasing the contact area with the exhaust gas, improving the adsorption and filtration effect on the exhaust gas); a plurality of bolts can be threadedly connected to the rod seat plate 441, which is convenient for connecting the rod seat plate 441 to the top opening of the filtering outer box 42 through the bolts after inserting the filtering rods 442 into the corresponding rectangular grooves 431.

[0054] On two opposite side walls of the box body 1, movable doors 6 are respectively hinged. Elastic plugging plates 61 corresponding to the outer wall positions of the filtering outer box 42 are arranged on the side walls of the movable doors 6, and when the movable doors 6 are closed, the elastic plugging plates 61 are in contact with the outer wall of the filtering outer box 42; when it is necessary to remove the filtering rod group 44 from the grid groove group 43, first open the movable doors 6. At this time, the elastic plugging plates 61 are separated from the outer wall of the filtering outer box 42, so as to facilitate rotating the motor 41 to drive the filtering outer box 42 to rotate 90 degrees, that is, making the rod seat plate 441 parallel to the side wall of the box body 1, so as to facilitate removing the filtering rod group 44 from the grid groove group 43; when the movable doors 6 are closed, the elastic plugging plates 61 are in contact with the outer wall of the filtering outer box 42. When the exhaust gas enters the box body 1 through the air inlet pipe 5, the exhaust gas can be prevented from flowing between the inner wall of the box body 1 and the outer wall of the filtering outer box 42.

[0055] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
