The exhaust gas treatment device includes a water tank assembly, a spray head, a first filter element and a water pump. The water tank assembly includes a spray water tank and a pumping tank, and the spray water tank is connected to the pumping tank; the spray head is arranged above the spray water tank; the first filter element is arranged between the spray water tank and the pumping tank, and the first filter element is provided with a first filter hole, and the first filter hole is respectively connected to the spray water tank and the pumping tank; the water pump is respectively connected to the pumping tank and the spray head.

[0004] In the above patent, the service life of the exhaust gas treatment device is extended by effectively reducing the clogging of the water pump and the sprinkler head. However, it is difficult to dissolve the solid particles in the exhaust gas in a centralized manner. If the solid particles are deposited or aggregated in the decomposition frame, it will cause uneven distribution of the exhaust gas flow, resulting in poor exhaust gas treatment effect in some areas. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an exhaust gas treatment device for catalyst decomposition, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: An exhaust gas treatment device for catalyst decomposition, comprising: a decomposition box, the decomposition box is arranged on the top of the ground, and a plasma treatment device is arranged inside the decomposition box, and the plasma treatment device is used for decomposing organic substances in the exhaust gas; a guiding pipe, the guiding pipe is fixedly installed on the right side of the decomposition box, and the guiding pipe is used for guiding the exhaust gas; an air inlet pipe, the air inlet pipe is fixedly installed on the circumferential surface of the guiding pipe; a sieve hole plate, the sieve hole plate is fixedly installed on the inner wall of the guiding pipe, and the sieve hole plate is used for separating solid particles in the exhaust gas; a servo motor, the servo motor is fixedly installed on the right side of the guiding pipe; a rotating rod, the rotating rod is fixedly installed on the output end of the servo motor; a curved panel, the curved panel is fixedly installed on the circumferential surface of the rotating rod, and the curved panel is used for pushing the solid particles on the right side of the sieve hole plate; a guiding hole, the guiding hole is opened on the circumferential surface of the guiding pipe; a feeding box, the feeding box is fixedly installed on the circumferential surface of the guiding pipe, and a dissolving liquid is arranged inside the feeding box; a feeding rod, the feeding rod is fixedly installed on the inner wall of the feeding box; a feeding frame, the feeding frame is slidably installed on the circumferential surface of the feeding rod; a feeding hole, the feeding hole is opened at the bottom of the feeding box, and the rotating rod rotates to contact the right side of the sieve hole plate and push the solid particles accumulated on the right side of the sieve hole plate.

[0007] According to the above technical solution, a first spring is arranged between the feeding rod and the feeding frame. When the feeding frame moves forward, the first spring is pulled. The first spring deforms and stores energy under the pull of the feeding frame. After the feeding frame disengages from the contact with the curved panel, the first spring can drive the feeding frame to return to the initial position. The feeding frame abuts against the guiding hole and the feeding hole.

[0008] According to the above technical solution, the curved panel abuts against the right side of the sieve hole plate. The curved panel is elastic. A rubber ring is arranged between the feeding frame and the feeding hole, and the rubber ring is used to increase the sealing effect between the feeding frame and the feeding hole. A linkage rod is fixedly installed on the circumferential surface of the rotating rod. When the curved panel rotates, the dissolving agent on the right side of the sieve hole plate is evenly smeared on the right side of the sieve hole plate and the solid particles on the right side of the sieve hole plate are dissolved.

[0009] According to the above technical solution, an adsorption assembly for pre-treating the exhaust gas is arranged on the inner wall of the air inlet pipe, and a buffer assembly is arranged on the inner wall of the air inlet pipe. The adsorption assembly includes a mesh frame, a load-bearing rod, a load-bearing frame, a T-shaped rod, a shielding plate, a replacement hole and a shielding hole. The mesh frame is fixedly installed on the inner wall of the air inlet pipe, the load-bearing rod is fixedly installed at the bottom of the mesh frame, the load-bearing frame is slidably installed on the circumferential surface of the load-bearing rod, the T-shaped rod rotates through the top of the mesh frame, the shielding plate is fixedly installed at the bottom of the T-shaped rod, the replacement hole is opened at the top of the mesh frame, the shielding hole is opened at the top of the shielding plate, and activated carbon particles are arranged inside the mesh frame. The reciprocating movement of the load-bearing frame squeezes the activated carbon inside the mesh frame.

[0010] According to the above technical solution, an elastic telescopic block is fixedly installed on the top of the mesh frame, a limiting rod is fixedly installed on the circumferential surface of the T-shaped rod, and the free end of the elastic telescopic block abuts against the top of the T-shaped rod.

[0011] According to the above technical solution, a torsion spring is arranged between the T-shaped rod and the mesh frame, and the T-shaped rod rotates counterclockwise to squeeze the torsion spring. The torsion spring is squeezed by the T-shaped rod to produce deformation and store force. After the T-shaped rod is manually released, the torsion spring can drive the T-shaped rod to restore its initial position. A second spring is arranged between the mesh frame and the load-bearing frame, and the load-bearing frame moves upward to squeeze the second spring. The second spring is squeezed by the load-bearing frame to produce deformation and store force. After the load-bearing frame is separated from the contact with the linkage rod, the second spring can drive the load-bearing frame to restore its initial position, and the free end of the elastic telescopic block moves upward to separate from the contact with the top of the T-shaped rod and releases the limit on the T-shaped rod.

[0012] According to the above technical solution, the buffer assembly includes a connecting tube, a cross groove, a rubber rod, a connecting plate, a buffer rod, a buffer plate and a buffer hole. The connecting tube is limited by the limiting rod and cannot move vertically. The connecting tube is slidably installed on the inner wall of the intake pipe. The cross groove is opened on the inner wall of the connecting tube. The rubber rod is fixedly installed on the circumferential surface of the intake pipe. The connecting plate is fixedly installed on the circumferential surface of the intake pipe. The buffer rod slides through the top of the connecting plate. The buffer plate is fixedly installed on the top of the buffer rod. The top of the buffer plate is fixedly connected to the connecting tube. The buffer hole is opened on the right side of the buffer plate.

[0013] According to the above technical solution, a spring three is arranged between the buffer plate and the connecting plate. The buffer plate moves downward to squeeze the spring three. The spring three is squeezed by the buffer plate to produce deformation and accumulate force. After the airflow inside the connecting pipe is stabilized, the spring three can drive the buffer plate to return to its initial position. The buffer plate is in conflict with the rubber rod, and the connecting plate is in conflict with the buffer hole. The buffer plate can only descend slowly, causing the connecting pipe to descend slowly and buffer the connecting pipe.

[0014] The present invention provides an exhaust gas treatment device for catalyst decomposition, which has the following beneficial effects:

[0015] (1) The exhaust gas treatment device for catalyst decomposition contacts the right side of the sieve plate through the rotation of the rotating rod and pushes the solid particles accumulated on the right side of the sieve plate. The accumulated solid particles will affect the flow of the exhaust gas, resulting in uneven gas distribution. The rotation of the rotating rod can help loosen and concentrate the solid particles, thereby ensuring the uniform flow of the exhaust gas inside the decomposition frame, thereby improving the exhaust gas treatment and separation effect. The fixed amount of solvent on the right side of the sieve plate is evenly applied to the right side of the sieve plate by rotating the curved plate and dissolving the solid particles on the right side of the sieve plate. The dissolved solid particles can reduce the resistance to gas flow, thereby further optimizing the overall exhaust gas treatment effect.

[0016] (2) In the exhaust gas treatment device for catalyst decomposition, the waste activated carbon inside the mesh frame is fully squeezed by the load-bearing frame and flows fully inside the mesh frame. The full flow of the activated carbon can increase the chance of contact between the activated carbon and the harmful substances in the exhaust gas, so that its surface can more effectively contact the pollutants in the exhaust gas, thereby improving the adsorption efficiency of the activated carbon.

[0017] (3) The exhaust gas treatment device for catalyst decomposition moves upward through the free end of the elastic telescopic block to break away from the contact with the top of the T-shaped rod and release the limit on the T-shaped rod. If the activated carbon leaks into the intake pipe and the guide pipe, it will cause secondary pollution to the exhaust gas. Limiting the T-shaped rod by the free end of the elastic telescopic block can prevent the activated carbon from leaking from the replacement hole.

[0018] (4) The exhaust gas treatment device for catalyst decomposition cannot move vertically due to the limit rod on the connecting pipe. By limiting the connecting pipe by the limit rod, it can prevent the connecting pipe from moving or detaching unnecessarily during maintenance, thereby reducing the risk of maintenance operations and improving safety.

[0019] (5) The exhaust gas treatment device for catalyst decomposition can only be slowly lowered through the buffer plate, so that the connecting pipe can be slowly lowered and the connecting pipe can be buffered. The slow lowering can ensure smooth flow guidance of the connecting pipe and avoid the impact generated during the exhaust gas intake process, thereby ensuring the safety of the decomposition frame and preventing the leakage of toxic exhaust gas.

Detailed implementation manners

[0022] 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.

[0023] Please refer to Figures 1-6 , an embodiment of the present invention is: an exhaust gas treatment device for catalyst decomposition, including: a decomposition box 1, the decomposition box 1 is arranged on the top of the ground, and a plasma treatment device is arranged inside the decomposition box 1, and the plasma treatment device is used for decomposing organic substances in the exhaust gas; a guiding pipe 2, the guiding pipe 2 is fixedly installed on the right side of the decomposition box 1, and the guiding pipe 2 is used for guiding the exhaust gas; an intake pipe 3, the intake pipe 3 is fixedly installed on the circumferential surface of the guiding pipe 2; a sieve plate 4, the sieve plate 4 is fixedly installed on the inner wall of the guiding pipe 2, and the sieve plate 4 is used for separating solid particles in the exhaust gas; a servo motor 5, the servo motor 5 is fixedly installed on the right side of the guiding pipe 2; a rotating rod 6, the rotating rod 6 is fixedly installed on the output end of the servo motor 5; a curved panel 7, the curved panel 7 is fixedly installed on the circumferential surface of the rotating rod 6, and the curved panel 7 is used for pushing the solid particles on the right side of the sieve plate 4; a guiding hole 8, the guiding hole 8 is opened on the circumferential surface of the guiding pipe 2; a feeding box 9, the feeding box 9 is fixedly installed on the circumferential surface of the guiding pipe 2, and a dissolving solution is arranged inside the feeding box 9; a feeding rod 10, the feeding rod 10 is fixedly installed on the inner wall of the feeding box 9; a feeding rack 11, the feeding rack 11 is slidably installed on the circumferential surface of the feeding rod 10; a feeding hole 12, the feeding hole 12 is opened at the bottom of the feeding box 9. The rotation of the rotating rod 6 can help loosen and concentrate the solid particles, so as to ensure the uniform flow of the exhaust gas inside the decomposition box 1, and further improve the exhaust gas treatment and separation effect.

[0024] A first spring is provided between the feeding rod 10 and the feeding frame 11. When the feeding frame 11 moves forward, it pulls the first spring. The first spring deforms and stores energy under the pull of the feeding frame 11. After the feeding frame 11 disengages from the contact with the curved panel 7, the first spring can drive the feeding frame 11 to return to its initial position. The feeding frame 11 abuts against the guiding hole 8 and the feeding hole 12.

[0025] The curved panel 7 abuts against the right side of the sieve hole plate 4. The curved panel 7 is elastic. A rubber ring is provided between the feeding frame 11 and the feeding hole 12, which is used to enhance the sealing effect between the feeding frame 11 and the feeding hole 12. A linkage rod 13 is fixedly installed on the circumferential surface of the rotating rod 6. When the curved panel 7 rotates, the dissolving agent guided to the right side of the sieve hole plate 4 is evenly smeared on the right side of the sieve hole plate 4, and the solid particles on the right side of the sieve hole plate 4 are dissolved. By dissolving the solid particles, the resistance to gas flow is reduced, thereby further optimizing the overall waste gas treatment effect.

[0026] During the operation of this embodiment: The waste gas generated by the decomposition of the catalyst is introduced into the decomposition frame 1 through the air inlet pipe 3 and the guiding pipe 2. At the same time, the servo motor 5 rotates to drive the rotating rod 6 to rotate. The rotating rod 6 rotates and contacts the right side of the sieve hole plate 4, and pushes the solid particles accumulated on the right side of the sieve hole plate 4. At the same time, the rotating rod 6 rotates and contacts the feeding frame 11, and squeezes the feeding frame 11. The feeding frame 11 moves forward under the extrusion of the curved panel 7. When the feeding frame 11 moves forward, the sealing of the guiding hole 8 is released. After the sealing of the guiding hole 8 is released, the dissolving agent in the feeding frame 9 is guided to the right side of the sieve hole plate 4 through the guiding hole 8 and the feeding hole 12. At the same time, the rotating rod 6 continues to rotate, driving the curved panel 7 to continue to rotate. The curved panel 7 continues to rotate and disengages from the contact with the feeding frame 11. After the feeding frame 11 disengages from the contact with the curved panel 7, the feeding frame 11 moves backward and resets under the elastic force of the first spring. When the feeding frame 11 moves backward and resets, the sealing of the feeding hole 12 is restored. The feeding frame 11 intermittently guides the dissolving agent in the feeding frame 9 to the right side of the sieve hole plate 4 through the guiding hole 8 and the feeding hole 12 during its reciprocating motion. At the same time, the curved panel 7 rotates to evenly smear the dissolving agent guided to the right side of the sieve hole plate 4 on the right side of the sieve hole plate 4 and dissolve the solid particles on the right side of the sieve hole plate 4.

[0027] Please refer to Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, an adsorption assembly for pre-treating exhaust gas is provided on the inner wall of the intake pipe 3, and a buffer assembly is provided on the inner wall of the intake pipe 3. The adsorption assembly includes a mesh frame 131, a load-bearing rod 132, a load-bearing frame 133, a T-shaped rod 134, a baffle plate 135, a replacement hole 137, and an occlusion hole 138. The mesh frame 131 is fixedly installed on the inner wall of the intake pipe 3, the load-bearing rod 132 is fixedly installed at the bottom of the mesh frame 131, the load-bearing frame 133 is slidably installed on the circumferential surface of the load-bearing rod 132, the T-shaped rod 134 rotatably penetrates the top of the mesh frame 131, the baffle plate 135 is fixedly installed at the bottom of the T-shaped rod 134, the replacement hole 137 is opened at the top of the mesh frame 131, and the occlusion hole 138 is opened at the top of the baffle plate 135. Activated carbon particles are provided inside the mesh frame 131. The sufficient flow of the activated carbon can increase the chance of contact between the activated carbon and the harmful substances in the exhaust gas, enabling its surface to more effectively contact the pollutants in the exhaust gas, thereby improving the adsorption efficiency of the activated carbon.

[0028] An elastic telescopic block 136 is fixedly installed at the top of the mesh frame 131, and a limiting rod 139 is fixedly installed on the circumferential surface of the T-shaped rod 134. The free end of the elastic telescopic block 136 abuts against the top of the T-shaped rod 134.

[0029] A torsion spring is provided between the T-shaped rod 134 and the mesh frame 131. When the T-shaped rod 134 rotates counterclockwise, the torsion spring is compressed. The torsion spring deforms and stores energy under the extrusion of the T-shaped rod 134. After manually releasing the T-shaped rod 134, the torsion spring can drive the T-shaped rod 134 to return to its initial position. A second spring is provided between the mesh frame 131 and the load-bearing frame 133. When the load-bearing frame 133 moves upward, the second spring is compressed. The second spring deforms and stores energy under the extrusion of the load-bearing frame 133. After the load-bearing frame 133 disengages from the contact with the linkage rod 13, the second spring can drive the load-bearing frame 133 to return to its initial position. The free end of the elastic telescopic block 136 moves upward to disengage from the contact with the top of the T-shaped rod 134 and releases the limitation on the T-shaped rod 134. Limiting the T-shaped rod 134 by the free end of the elastic telescopic block 136 can prevent the activated carbon from leaking from the replacement hole 137.

[0030] The buffer assembly includes a connecting pipe 141, a cross groove 142, a rubber rod 143, a connecting plate 144, a buffer rod 145, a buffer plate 146 and buffer holes 147. The connecting pipe 141 is used to connect with an external pipeline. The connecting pipe 141 is slidably installed on the inner wall of the intake pipe 3. The cross groove 142 is opened on the inner wall of the connecting pipe 141. The rubber rod 143 is fixedly installed on the circumferential surface of the intake pipe 3. The connecting plate 144 is fixedly installed on the circumferential surface of the intake pipe 3. The buffer rod 145 slidably penetrates through the top of the connecting plate 144. The buffer plate 146 is fixedly installed on the top of the buffer rod 145. The top of the buffer plate 146 is fixedly connected to the connecting pipe 141. The buffer holes 147 are opened on the right side of the buffer plate 146. By restricting the connecting pipe 141 with the limiting rod 139, unnecessary movement or detachment during maintenance can be prevented, thereby reducing the risk in maintenance operations and improving safety.

[0031] A third spring is arranged between the buffer plate 146 and the connecting plate 144. When the buffer plate 146 moves downward, it squeezes the third spring. The third spring deforms and stores energy under the extrusion of the buffer plate 146. After the airflow inside the connecting pipe 141 stabilizes, the third spring can drive the buffer plate 146 to return to the initial position. The buffer plate 146 abuts against the rubber rod 143, and the connecting plate 144 abuts against the buffer holes 147. The buffer plate 146 can only slowly descend, causing the connecting pipe 141 to slowly descend and buffer the connecting pipe 141. By slowly descending, it can ensure the smooth diversion of the connecting pipe 141, avoid the impact generated during the intake of waste gas, and thus ensure the safety of the decomposition frame 1 and prevent the leakage of toxic waste gas.

[0032] During the operation of this embodiment: The rotating rod 6 rotates to drive the linkage rod 13 to rotate. The linkage rod 13 rotates and contacts the inclined surface at the bottom of the load-bearing frame 133 and squeezes the load-bearing frame 133. The load-bearing frame 133 moves upward under the extrusion of the linkage rod 13. When the rotating rod 6 continues to rotate to drive the linkage rod 13 to continue rotating, the linkage rod 13 continues to rotate and disengages from the contact with the load-bearing frame 133. After the load-bearing frame 133 disengages from the contact with the linkage rod 13, the load-bearing frame 133 moves downward and resets under the elastic force of the second spring. The reciprocating motion of the load-bearing frame 133 squeezes the activated carbon inside the mesh frame 131. The waste activated carbon inside the mesh frame 131 flows fully inside the mesh frame 131 under the reciprocating extrusion of the load-bearing frame 133. When it is necessary to replace the activated carbon inside the mesh frame 131, manually push the free end of the elastic telescopic block 136 upward. The free end of the elastic telescopic block 136 moves upward and disengages from the contact with the top of the T-shaped rod 134, releasing the limit on the T-shaped rod 134. After the limit on the T-shaped rod 134 is released, manually rotate the T-shaped rod 134 counterclockwise. The T-shaped rod 134 rotates counterclockwise to drive the baffle 135 to rotate. The rotation of the baffle 135 aligns the replacement hole 137 with the shielding hole 138. After the replacement hole 137 is aligned with the shielding hole 138, the activated carbon inside the mesh frame 131 is replaced through the replacement hole 137.

[0033] The counterclockwise rotation of the T-shaped rod 134 drives the counterclockwise rotation of the limit rod 139. The counterclockwise rotation of the limit rod 139 contacts the right inner wall of the cross slot 142 and limits the connecting pipe 141. The connecting pipe 141 is limited by the limit rod 139 and cannot move vertically. After the activated carbon inside the mesh frame 131 is replaced, the T-shaped rod 134 is released, so that the T-shaped rod 134 rotates clockwise and resets under the elastic force of the torsion spring. The clockwise rotation and reset of the T-shaped rod 134 drives the clockwise rotation and reset of the limit rod 139. The clockwise rotation and reset of the limit rod 139 contacts the middle part of the inner wall of the cross slot 142 and releases the limit on the connecting pipe 141. After the limit on the connecting pipe 141 is released, if a strong impact occurs when the waste gas enters the decomposition frame 1, the impact force generated by the waste gas will squeeze the connecting pipe 141. The connecting pipe 141 moves downward under the extrusion force of the waste gas. The downward movement of the connecting pipe 141 drives the downward movement of the buffer plate 146. The downward movement of the buffer plate 146 contacts the rubber rod 143 and squeezes the rubber rod 143. The rubber rod 143 is slowly deformed under the extrusion of the buffer plate 146. The slow deformation of the rubber rod 143 enables the buffer plate 146 to only slowly descend. The fact that the buffer plate 146 can only slowly descend enables the connecting pipe 141 to slowly descend and cushions the connecting pipe 141.
