[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 dissolving agent 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) The waste gas treatment device for catalyst decomposition is characterized by the waste activated carbon inside the mesh frame being squeezed back and forth by the load-bearing frame and flowing 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 waste gas, so that its surface can more effectively contact the pollutants in the waste gas, thereby improving the adsorption efficiency of the activated carbon.

[0017] (3) The exhaust gas treatment device for catalyst decomposition moves upward by 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 limitation of the connecting pipe by the limiting rod. By limiting the connecting pipe by the limiting rod, it can prevent the connecting pipe from unnecessary movement or separation 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 by the buffer plate, so that the connecting pipe can be slowly lowered and the connecting pipe can be buffered. By slowly lowering, the connecting pipe can be ensured to guide the flow smoothly, avoiding 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.

[0030] A spring 1 is provided between the feeding rod 10 and the feeding rack 11. The feeding rack 11 moves forward to pull the spring 1. The spring 1 is deformed and stores force due to the pulling of the feeding rack 11. After the feeding rack 11 breaks away from the contact with the curved plate 7, the spring 1 can drive the feeding rack 11 to restore its initial position. The feeding rack 11 conflicts with the guide hole 8, and the feeding rack 11 conflicts with the feeding hole 12.

[0031] The curved panel 7 is in contact with the right side of the sieve plate 4. The curved panel 7 is elastic. A rubber ring is provided between the feeding rack 11 and the feeding hole 12. The rubber ring is used to increase the sealing effect between the feeding rack 11 and the feeding hole 12. A linkage rod 13 is fixedly installed on the circumferential surface of the rotating rod 6. The curved panel 7 rotates to evenly apply the solvent directed to the right side of the sieve plate 4 to the right side of the sieve plate 4 and dissolve the solid particles on the right side of the sieve plate 4. The dissolution of the solid particles can reduce the resistance to gas flow, thereby further optimizing the overall exhaust gas treatment effect.

[0032] When this embodiment is working: the catalyst is decomposed through the air inlet pipe 3 and the guide pipe 2 to introduce the generated exhaust gas into the decomposition frame 1, and at the same time, the servo motor 5 rotates to drive the rotating rod 6 to rotate, and the rotating rod 6 rotates to contact the right side of the sieve plate 4 and push the solid particles accumulated on the right side of the sieve plate 4. At the same time, the rotating rod 6 rotates to contact the feeding rack 11 and squeeze the feeding rack 11. The feeding rack 11 is squeezed to the front side by the curved plate 7, and the feeding rack 11 moves forward to release the seal of the guide hole 8.

[0033] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, an adsorption component for pre-treating the exhaust gas is provided on the inner wall of the intake pipe 3, a buffer component is provided on the inner wall of the intake pipe 3, and the adsorption component includes a mesh frame 131, a load-bearing rod 132, a load-bearing frame 133, a T-shaped rod 134, a shielding plate 135, a replacement hole 137 and a shielding hole 138. The mesh frame 131 is fixedly mounted on the inner wall of the intake pipe 3, the load-bearing rod 132 is fixedly mounted on the bottom of the mesh frame 131, and the load-bearing frame 133 is slidably mounted. On the circumferential surface of the load-bearing rod 132, the T-shaped rod 134 rotates and passes through the top of the mesh frame 131, the baffle 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 baffle hole 138 is opened at the top of the baffle 135. Activated carbon particles are arranged inside the mesh frame 131. The full flow of activated carbon can increase the chance of contact between activated carbon and 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 activated carbon.

[0034] An elastic expansion block 136 is fixedly installed on the top of the mesh frame 131 , a limiting rod 139 is fixedly installed on the circumferential surface of the T-shaped rod 134 , and the free end of the elastic expansion block 136 contacts the top of the T-shaped rod 134 .

[0035] The spring 136 is pressed against the top of the T-bar 134 to release the limit of the T-bar 134, and the free end of the elastic telescopic block 136 moves upward to break away from the contact with the top of the T-bar 134 and release the limit of the T-bar 134. The free end of the elastic telescopic block 136 limits the T-bar 134 to prevent the activated carbon from leaking from the replacement hole 137.

[0036] The buffer assembly includes a connecting tube 141, a cross groove 142, a rubber rod 143, a connecting plate 144, a buffer rod 145, a buffer plate 146 and a buffer hole 147. The connecting tube 141 is used to connect to an external pipeline. The connecting tube 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 tube 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 slides 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 tube 141. The buffer hole 147 is opened on the right side of the buffer plate 146. The connecting tube 141 is restricted by the limit rod 139 to prevent it from unnecessary movement or detachment during maintenance, thereby reducing the risk in maintenance operations and improving safety.

[0037] A spring three is provided between the buffer plate 146 and the connecting plate 144. The buffer plate 146 moves downward to squeeze the spring three. The spring three is squeezed by the buffer plate 146 to produce deformation and store force. After the airflow inside the connecting pipe 141 stabilizes, the spring three can drive the buffer plate 146 to return to its initial position. The buffer plate 146 contacts the rubber rod 143, and the connecting plate 144 contacts the buffer hole 147. The buffer plate 146 can only descend slowly, causing the connecting pipe 141 to slowly descend and buffer the connecting pipe 141. By slowly descending, the connecting pipe 141 can be ensured to guide the flow smoothly, avoiding the impact generated during the exhaust gas intake process, thereby ensuring the safety of the decomposition frame 1 and preventing the leakage of toxic exhaust gas.

[0038] When this embodiment is working, the rotation of the rotating rod 6 drives the linkage rod 13 to rotate, and the linkage rod 13 rotates to contact the inclined surface at the bottom of the load-bearing frame 133 and squeeze the load-bearing frame 133. The load-bearing frame 133 is squeezed upward by the linkage rod 13, and the rotating rod 6 continues to rotate to drive the linkage rod 13 to continue to rotate. The linkage rod 13 continues to rotate and disengages from the contact with the load-bearing frame 133. After the load-bearing frame 133 is disengaged from the contact with the linkage rod 13, the load-bearing frame 133 moves downward and resets under the elastic force of the spring 2. The reciprocating motion of the load-bearing frame 133 squeezes the activated carbon inside the mesh frame 131, and the waste activated carbon inside the mesh frame 131 is squeezed back and forth by the load-bearing frame 133. When the mesh frame 131 is fully flowing and the activated carbon inside the mesh frame 131 needs to be replaced, the free end of the elastic telescopic block 136 is manually pushed upward. The free end of the elastic telescopic block 136 moves upward to break away from the contact with the top of the T-shaped rod 134 and releases the limit on the T-shaped rod 134. After the limit of the T-shaped rod 134 is released, the T-shaped rod 134 is manually rotated counterclockwise. The counterclockwise rotation of the T-shaped rod 134 drives the baffle 135 to rotate. The baffle 135 rotates to align the replacement hole 137 with the baffle hole 138. After the replacement hole 137 is aligned with the baffle hole 138, the activated carbon inside the mesh frame 131 is replaced through the replacement hole 137.

[0039] The T-shaped rod 134 rotates counterclockwise to drive the limiting rod 139 to rotate counterclockwise, and the limiting rod 139 rotates counterclockwise to contact the right side of the inner wall of the cross groove 142 and limit the connecting tube 141. The connecting tube 141 is limited by the limiting rod 139 and cannot move vertically. After the activated carbon inside the mesh frame 131 is replaced, the T-shaped rod 134 is loosened so that the T-shaped rod 134 rotates clockwise to reset under the elastic force of the torsion spring. The clockwise rotation and reset of the T-shaped rod 134 drives the limiting rod 139 to rotate clockwise to reset. The limiting rod 139 rotates clockwise to reset and contacts the middle of the inner wall of the cross groove 142 and releases the limit on the connecting tube 141. After the limit of 141 is released, if the exhaust gas generates a strong impact when entering the decomposition frame 1, the impact force generated by the exhaust gas will squeeze the connecting pipe 141, and the connecting pipe 141 moves downward due to the squeezing force of the exhaust gas. The downward movement of the connecting pipe 141 drives the buffer plate 146 to move downward, and the buffer plate 146 moves downward and contacts the rubber rod 143 and squeezes the rubber rod 143. The rubber rod 143 is squeezed by the buffer plate 146 and slowly deformed. The rubber rod 143 slowly deforms, so that the buffer plate 146 can only slowly descend. The buffer plate 146 can only slowly descend, so that the connecting pipe 141 slowly descends and buffers the connecting pipe 141.
