[0002] A VOCs catalytic combustion unit is an environmentally friendly device used to treat industrial waste gas. It converts organic waste gas into harmless carbon dioxide and water through catalytic combustion technology. The core of the unit lies in its catalyst, which can promote the oxidation reaction of organic matter at a lower temperature, thereby reducing energy consumption and improving treatment efficiency.

[0003] The specific working principle of the VOCs catalytic combustion device is to pass the exhaust gas through a dry filter to remove particulate matter, and then enter the activated carbon adsorption box for adsorption and concentration. When the activated carbon is saturated, it is desorbed and oxidized and decomposed through the catalytic burner. The reaction process is carried out under the action of the catalytic bed, with the purpose of converting organic waste gas into carbon dioxide and water.

[0005] However, the VOCs adsorption-desorption-catalytic combustion device also has the following defects:

[0006] The filter components and pipes in the adsorption and desorption components are prone to clogging because the V0Cs exhaust gas contains a large amount of particulate matter, condensate after pollution, and coagulated flocs. These pollutants will be blocked at the filter port after passing through the filter components. Summary of the Invention

[0016] An air inlet is passed through one end of the waste gas transfer chamber away from the guide pipe, and the air inlet introduces the waste gas.

[0017] Furthermore, connecting plates are installed on both sides of the connecting channel, and a first linear motor is installed on the side of the connecting plate close to the connecting channel. The output end of the first linear motor is connected to a first transmission guide rail, and a first transmission slider is installed on the first transmission guide rail. The first linear motor drives the first transmission slider to slide on the first transmission guide rail through magnetic force.

[0018] Furthermore, the top and bottom ends of the connecting plate away from the first linear motor are installed with limiting slide rails, and the limiting slide rails are slidably connected to the movable support plate.

[0019] Wherein, the first transmission slider is fixed through a connecting piece and the bottom end of the movable support plate.

[0020] Furthermore, a second linear motor is installed on one side of the movable support plate, and the output end of the second linear motor is connected to a second transmission rail, and a second transmission slider is installed on the second transmission rail. The second linear motor drives the second transmission slider to slide on the second transmission rail through magnetic force.

[0022] Furthermore, a transmission rocker is hinged on one side of the second transmission slider, and a transmission gear is hinged on the top of the transmission rocker. When the second transmission slider is raised or lowered, the transmission gear is driven to rotate by the transmission rocker.

[0023] Wherein, a flip bracket is installed on one side of the transmission gear, and a connecting thin plate is fixed at the middle position of the flip bracket, and the connecting thin plate rotates around the axis of the flip bracket.

[0024] Furthermore, electric push rods are installed at the top and bottom ends of the connecting plate near one end of the filtering structure, and the electric push rods are retractable.

[0032] A rubber sealing head is fixed at the connection between the connecting bracket and the cleaning claw.

[0033] The present invention provides a VOCs catalytic combustion device through improvement, which has the following improvements and advantages compared with the prior art:

[0034] First, when the device is working, the material is fed through the air inlet, passes through the exhaust gas transfer bin and the guide pipe, and finally reaches the catalytic combustion bin for catalytic combustion reaction. The main improvement of this device is to clear the drainage hole by inserting the cleaning claw into the drainage hole, which is convenient for clearing the filter components and pipes in the adsorption and desorption components, thereby avoiding blockage. Because V0Cs exhaust gas contains a large amount of particulate matter, condensate after pollution, and coagulated flocs, the large particles of these pollutants are easily blocked in the drainage hole after passing through the porous fiberboard of the filter component.

[0035] Secondly, after the cleaning claw is inserted into the drainage hole, the cleaning brush behind the cleaning claw rubs the pollutants stuck on the inner wall of the drainage hole to make them fall off, and then by starting the rotating motor, the rotating motor drives the double-threaded screw to rotate, and the double-threaded screw drives the moving slider to move along the axis of the double-threaded screw through the thread, thereby driving the cleaning claw to grab the pollutants accumulated in the drainage hole and filtered by the porous fiberboard. In addition, the double-threaded screw is a double-threaded design, which allows the cleaning claw to repeat the above actions to grab and clean the pollutants. The two ends of the connecting bracket are respectively connected to the cleaning claw and the cleaning brush to facilitate stabilizing the position of the cleaning claw. At the same time, the telescopic rod can be extended and retracted according to the movement of the cleaning claw, so as to further stabilize the cleaning claw. The rubber sealing head is made of soft rubber material, which can block the outlet at the top of the drainage hole when the cleaning claw cleans the drainage hole, so as to clean the drainage hole more thoroughly.

[0036] Thirdly, by starting the second linear motor, the second transmission slider is driven by magnetic force to move along the second transmission slide rail. When the second transmission slider moves, the transmission rocker is driven to drive the transmission gear to rotate through the transmission, and the transmission gear drives the flip bracket to flip, thereby driving the connecting thin plate to flip around the flip bracket. The function of the flip is to adjust the angle of the cleaning claw in the cleaning component after it is inserted into the drainage hole, so as to further improve the cleaning effect of the cleaning claw. The function of the electric push rod is to push the adjustment pressure plate and the cleaning component on one side toward the drainage hole.

[0037] At the same time, there are three groups of diversion channels, which can clean the drainage holes without affecting the exhaust gas filtration. Specifically, the first linear motor is started to drive the first transmission slider to move along the first transmission guide rail through transmission. The first transmission slider drives the movable support plate connected to the other side of the connecting plate to move along the limiting slide rail, so as to facilitate moving the cleaning component to the position of a certain group of diversion channels that need to be cleaned.

In addition, the double-threaded screw 617 is a double-threaded design, so that the cleaning claw 622 can repeat the above actions to grab and clean the pollutants.

[0075] Among them, telescopic rods 619 are distributed in a ring around the movable slider 618, and the telescopic rods 619 are retractable. The telescopic rods 619 and the movable slider 618 are hingedly connected;

[0076] A cleaning claw 622 is installed on the side of the telescopic rod 619 away from the movable slider 618. At the same time, the telescopic rod 619 can be extended and retracted according to the movement of the cleaning claw 622, thereby further stabilizing the cleaning claw 622.

The main improvement of this device is that the cleaning claw 622 is inserted into the drainage hole 505 to achieve the effect of unblocking the drainage hole 505, which is convenient for unblocking the filter components and pipelines in the adsorption and desorption components, thereby achieving the effect of avoiding blockage, because V0Cs exhaust gas contains a large amount of particulate matter, condensate after pollution, and solidified flocs. The large particles of these pollutants are easily blocked in the drainage hole 505 after passing through the porous fiberboard 506 of the filter component.

[0082] Then, after the cleaning claw 622 is inserted into the drainage hole 505, the cleaning brush 623 behind the cleaning claw 622 rubs the pollutants adhered to the inner wall of the drainage hole 505 to make them fall off, and then by starting the rotating motor 616, the rotating motor 616 drives the double-threaded screw 617 to rotate.

The two ends of the connecting bracket 620 are respectively connected to the cleaning claw 622 and the cleaning brush 623, which is convenient for stabilizing the position of the cleaning claw 622. At the same time, the telescopic rod 619 can be extended and retracted according to the movement of the cleaning claw 622, so as to further stabilize the cleaning claw 622. The rubber sealing head 621 is made of soft rubber material, which can block the outlet at the top of the drainage hole 505 when the cleaning claw 622 cleans the drainage hole 505, so as to clean the drainage hole 505 more thoroughly.

[0083] Finally, the second linear motor 607 is started to drive the second transmission slide 610 to move along the second transmission slide 610 through magnetic force. When the second transmission slide 610 moves, the transmission rocker 611 is driven to drive the transmission gear 612 to rotate, and the transmission gear 612 drives the flip bracket 613 to flip, thereby driving the connecting thin plate 624 to flip around the flip bracket 613. The function of the flip is to adjust the angle of the cleaning claw 622 in the cleaning component after it is inserted into the drainage hole 505, so as to further improve the cleaning effect of the cleaning claw 622. The function of the electric push rod 614 is to push the adjustment pressure plate 615 and the cleaning component on one side toward the drainage hole 505.
