Technical elements of environmentally friendly exhaust gas treatment three-way catalytic converters

Technical realization elements:

4. In view of the shortcomings of the existing three-way catalytic converters in the use process proposed in the background art, the present invention provides a three-way catalytic converter for exhaust gas treatment for environmental protection, which has the advantages of pressurization, temperature rise, deformation and block removal, It solves the technical problems that the three-way catalytic converter cannot reach the working temperature quickly and the internal blockage affects the working efficiency when the three-way catalytic converter is in normal use.

5. The present invention provides the following technical solutions: a three-way catalytic converter for exhaust gas treatment for environmental protection, comprising a tube body, the middle of the left end of the tube body is provided with an air inlet, and the middle of the right end of the tube body is provided with an air outlet A piston barrel is movably sleeved in the middle of the inner cavity of the tube, and the side of the piston barrel is provided with a connecting hole connecting the outside world and the inner cavity, and the right side of the piston barrel and the right side of the inner cavity of the tube are movably connected by a spring A vent groove is opened on the side surface of the inner cavity of the tube, and the vent groove is located outside the connecting hole of the piston cylinder.

6. Preferably, the deforming block is a rhombus that can move freely, the left side of the piston barrel is fixedly connected with a limiting plate, the middle of the limiting plate is movably sleeved with a piston plate, and the left side of the deforming block It is fixedly connected with the right side of the piston plate, and the right side of the deformable block is fixedly connected with the right side of the inner cavity of the rotating cylinder.

7. Preferably, the aeration groove is eccentrically opened.

8. Preferably, the inner side of the tube body is provided with a liquid storage cavity below the limit plate, the upper end of the liquid storage cavity is movably sleeved with the limit rod, and the right side of the piston plate is provided with an adjustment groove, And the upper end of the limit rod and the inner side of the adjusting groove are movably clamped.

9. Preferably, the depth of the upper and lower sides of the adjustment groove is uneven.

10. The present invention has the following beneficial effects:

11.1 In the present invention, a booster and temperature rise mechanism is provided so that when the three-way catalytic converter is initially exhausted, the spring and activation

With the cooperation of the plug tube, the ventilation groove is closed in a dislocation, so that the gas discharged through the automobile exhaust system is collected in the three-way catalyst, and the air pressure gradually increases, thereby releasing heat outward under the action of the reduction of the gas volume , Make the three-way catalytic converter heat up quickly, and after the internal air pressure increases to a certain degree or the internal temperature reaches a certain level, the piston cylinder moves to the right to open the ventilation groove, so that the three-way catalytic converter can catalytically treat the exhaust gas .

12.2 The present invention sets up a blocking reversing mechanism, so that when the three-way catalytic converter is too long and the internal catalytic part is blocked, under the action of the eccentric opening of the ventilation groove and the gradual increase of the air pressure in the three-way catalytic converter, the to-be-exhausted The exhaust gas produces a certain thrust on the deformed block, which causes the deformed block to drive the rotating cylinder to rotate vertically, thereby changing the flow path of the exhaust gas, so that the three-way catalytic converter can continue to work, preventing the traditional three-way catalytic converter from being blocked inside. Emergency treatment of exhaust gas occurred.

13.3. In the present invention, a deformation cleaning mechanism is provided, so that when the three-way catalytic converter is too long and the internal catalytic part is blocked, under the action of the blocking reversing mechanism, the deformation block drives the rotating cylinder to rotate vertically. Due to the uneven depth and the limiting rod on the left side of the piston plate, the position of the piston plate continuously changes left and right, so that the distance between the right side of the rotating cylinder and the piston plate changes, and the deformation blocks continue to occur. Deformation changes the attachment point of the blockage blocked in the deformed block, ruptures the blockage, and completes the block removal under the cooperation of the tail gas impact.
