Description

Technical Field

[0001] The present invention relates to the field of VOCs waste gas treatment, and in particular to a VOCs waste gas treatment device and system. Background Art

[0002] VOCs waste gas is a volatile organic compound. The composition of VOCs waste gas varies depending on the production environment and process. The waste gas treatment methods are also different for different VOCs waste gas properties. When VOCs waste gas contains some or a large amount of solid dust particles and other pollutants, gas-solid separation pretreatment is required before treatment.

[0003] In the existing technology, the VOCs waste gas gas-solid separation pretreatment device often only connects the waste gas to the air intake pipe installed on one side of the device, pours the waste gas into the device, and filters it through a filter bag. During the filtration process, multiple switchable devices need to be set up for coordinated use.

[0004] However, in actual use, it is difficult to automatically seal the air supply pipe leading to the device, which can easily cause exhaust gas to leak into the air. It is difficult to effectively separate the solid particles and gas in the VOCs exhaust gas, and a small amount of the separated solids may adhere to the filter bag and be difficult to clean.

[0005] Therefore, we proposed a VOCs waste gas treatment equipment and system to solve the problem of incomplete waste gas treatment caused by the difficulty in separating solid particles in the existing VOCs waste gas, and to achieve effective treatment of VOCs waste gas. Summary of the Invention

[0035] Example 2

[0036] On the basis of Example 1, in order to achieve sealed air intake of VOCs exhaust gas, this embodiment adds an air supply mechanism: the air supply mechanism includes a fixed sealing plate 6 and a movable sealing plate 8, the fixed sealing plate 6 is fixedly installed on the inner wall of one end of the air supply pipe 5, and an air inlet hole 61 for air intake is provided on the outer inner wall of the fixed sealing plate 6, and an air guide column 62 is installed on the inner wall of the air inlet hole 61 in a one-to-one correspondence, and a magnet receiving groove 64 is provided on the inner wall of the air guide column 62 on the side close to the movable sealing plate 8, an electromagnet 65 is fixedly installed on the inner surface of the magnet receiving groove 64, a spring receiving groove 71 is provided on the inner side of the magnet receiving groove 64, and a reset spring 7 is fixedly installed on the inner side of the spring receiving groove 71, and the reset spring 7 and the spring receiving groove 71 are both arranged at the center position of the fixed sealing plate 6, and a sealing plug column 63 is fixedly installed on the inner wall of the side of the fixed sealing plate 6 close to the movable sealing plate 8, and the outer side of the sealing plug column 63 is movable An air guide column 81 is plugged in and installed on the inner wall of the movable sealing plate 8, and the output end of the air guide column 81 is fixedly connected to the jet elbow 9. A sealing plug column 82 corresponding to the air guide column 1 62 is fixedly installed on the surface of the movable sealing plate 8 close to the fixed sealing plate 6. A pushing assembly is provided on the side of the movable sealing plate 8 away from the fixed sealing plate 6. The pushing assembly includes a connecting wire column 10. One end of the connecting wire column 10 is fixedly connected to the outer surface of the movable sealing plate 8. The end of the connecting wire column 10 away from the movable sealing plate 8 is fixedly installed with a push plate 11 that is slidably connected to the inner wall of the air supply pipe 5. An auxiliary ash pushing assembly is fixedly added to the lower end of the push plate 11. A push pin 12 is fixedly installed on the end of the push plate 11 away from the connecting wire column 10. The push pin 12 is set on the central axis of the push plate 11, and the outer surface of the push pin 12 is externally movably abutted against the spray control switch 14 installed on the inner side of the lower end of the fixed frame 13.

[0037] When the VOCs waste gas is input into the waste gas treatment equipment body 1 through the air inlet end of the air supply pipe 5, the waste gas is introduced into the air supply pipe 5 through multiple groups of air inlet holes 61 and air guide column 1 62, and the air guide column 2 81 corresponding to the sealing plug column 1 63 on the inner side of the fixed sealing plate 6 is separated from it, and the sealing plug column 2 82 is separated from the air guide column 1 62, and the return spring 7 is stretched and deformed by the tension of the movable sealing plate 8, and the introduced VOCs waste gas is ejected outward through the jet elbow 9, and the push plate 11 and the ejector pin 12 are moved toward the side of the spray control switch 14 by the top thrust of the movable sealing plate 8, and the lower part of the push plate 11 The side is staggered with the air intake filter plate 51. At this time, the VOCs exhaust gas introduced passes through the air intake filter plate 51 into the interior of the inner filter tube 2, and the ejector pin 12 and the spray control switch 14 are always in conflict, thereby automatically triggering the spray solid reduction mechanism. The reason for adding the magnet receiving groove 64 is to accommodate the electromagnet 65, and the reason for opening the spring receiving groove 71 is to accommodate the contraction reset spring 7 to prevent affecting the effective closure of the fixed sealing plate 6 and the movable sealing plate 8, further solving the problem that solid particles in the existing VOCs exhaust gas are difficult to separate, resulting in incomplete exhaust gas treatment, and can achieve effective treatment of VOCs exhaust gas.

[0038] Example 3

[0039] On the basis of Example 2, in order to achieve effective separation between gaseous and solid particles in the VOCs exhaust gas introduced into the inner filter cartridge 2, this embodiment adds a spraying solid reduction mechanism: the spraying solid reduction mechanism includes a liquid pump 15, the liquid pump 15 is installed at the bottom of the inner cavity of the liquid storage tank 4, the output end of the liquid pump 15 is fixedly installed with a liquid delivery pipe 17 extending to the interior of the inner filter cartridge 2, the outside of the liquid delivery pipe 17 is rotatably installed with a rotating seat 16, the output end of the rotating seat 16 is fixedly installed with a conical liquid storage bucket 18, the lower end of the conical liquid storage bucket 18 is connected through with a hexagonal plate 19, and the lower end of the hexagonal plate 19 is evenly distributed with spray buckets 20, the hexagonal plate 19 is configured as a hollow hexagonal structure as a whole, and the sides of the hexagonal plate 19 are respectively fixedly provided with a liquid delivery elbow 191 and a spray storage plate 192, the liquid delivery elbow 191 and the spray storage plate 192 are arranged in a circular array with the central axis of the hexagonal plate 19, and the lower end output end of the spray storage plate 192 is fixedly provided with a drainage hole.

[0040] When the ejector pin 12抵触 the spray control switch 14, the liquid pump 15 is turned on at this time, automatically extracting the solid-reducing liquid inside the liquid storage tank 4. The liquid is stored inside the conical liquid storage hopper 18 and the hexagonal plate 19 through the liquid delivery pipe 17, and is sprayed out through multiple groups of liquid delivery elbow pipes 191 at this time. Under the action of the liquid delivery elbow pipes 191, a reverse spraying force is given to the spray storage plate 192, ensuring that the spray storage plate 192 drives the hexagonal plate 19 to rotate as a whole. At this time, the rotating seat 16 assists the hexagonal plate 19 to rotate as a whole, ensuring that the drain holes are mixed with the solid particles in the waste gas inside the inner filter cylinder 2 of the spraying hopper 20, completing dust reduction, and further solving the problem that solid particles in the existing VOCs waste gas are difficult to separate, resulting in incomplete waste gas treatment, and can effectively treat VOCs waste gas.

[0041] Embodiment Four

[0042] On the basis of Embodiment Three, in order to automatically clean the solid particles adhered to the lower side of the inner filter cylinder 2 and prevent the particles from blocking the filter holes and affecting the gas-solid separation effect, this embodiment adds a power self-cleaning mechanism: The power self-cleaning mechanism includes a servo motor 22 and a sliding seat 25. The servo motor 22 is fixedly installed on the inner bottom surface of the protective ring cover 21. A driving pawl wheel 23 is fixedly installed on the output shaft of the servo motor 22. A meshing tooth ring 24 rotatably engaged with the outer surface of the waste gas treatment equipment body 1 is rotatably engaged on the outer surface of one side of the driving pawl wheel 23. A magnetic attraction block one is fixedly added to the lower side surface of the meshing tooth ring 24. The overall shape of the sliding seat 25 is a "U"-shaped plate structure, and a magnetic attraction block two corresponding to the magnetic attraction block one is arranged inside the sliding seat 25. The outer surface of the sliding seat 25 is rotatably connected to the outer surface of a convex ring 251 fixedly added to the inner side of the lower end of the waste gas treatment equipment body 1. A cleaning plate 26 is fixedly installed on one side of the sliding seat 25 away from the convex ring 251. The outer surface of the cleaning plate 26 is movably connected to the outer surface of the inner filter cylinder 2.

[0043] The servo motor 22 is electrically connected to the liquid pump 15. When the spray control switch 14 controls the opening, the liquid pump 15 and the servo motor 22 are driven synchronously. At this time, the servo motor 22 drives the rotation of its output shaft as the center of power transmission, and drives the driving pawl wheel 23 to rotate. Under the action of the meshing tooth force, the meshing tooth ring 24 rotates synchronously. At this time, the magnetic attraction block one fixedly added to the lower end of the meshing tooth ring 24 is magnetically attracted to the magnetic attraction block two, thereby driving the sliding seat 25 and the cleaning plate 26 to rotate along the movement path of the magnetic attraction block one. At this time, the cleaning plate 26 reciprocally sweeps the outer wall of the inner filter cylinder 2, preventing the automatic cleaning of solid particles accumulated at the lower end of the inner filter cylinder 2, further solving the problem that solid particles in the existing VOCs waste gas are difficult to separate, resulting in incomplete waste gas treatment, and can effectively treat VOCs waste gas.

[0044] Embodiment Five

[0045] On the basis of Example 4, in order to achieve the sealing between the staggered air guide columns between the fixed sealing plate 6 and the movable sealing plate 8, electromagnet 2 83 is respectively provided on the outer side of the sealing plug column 2 82, and the electromagnet 2 83 corresponds to the magnetic pole of the electromagnet 1 65 installed on the inner wall of the magnet receiving groove 64, and the electromagnet 1 65 and the electromagnet 2 83 are electrically connected.

[0046] When it is necessary to stop spraying, electromagnet 1 65 is energized. At this time, electromagnet 1 65 and electromagnet 2 83 are attracted to each other by the principle of opposite magnetic poles, and the movable sealing plate 8 approaches the side of the fixed sealing plate 6. At this time, the reset spring 7 is contracted, and the sealing plug column 1 63 and the air guide column 2 81, and the air guide column 1 62 and the sealing plug column 2 82 are correspondingly plugged in, thereby completing the automatic blocking of the air inlet 61, further solving the problem of incomplete waste gas treatment caused by the difficulty in separating solid particles in the existing VOCs waste gas, and realizing effective treatment of VOCs waste gas.

[0047] Example 6

[0048] On the basis of Example 5, in order to achieve the effect of avoiding clogging of solid particles in the surface of the air intake filter plate 51 when exhaust gas is transmitted for a long time, this embodiment adds an auxiliary ash pushing component, which includes a rubber arc plate 111. The rubber arc plate 111 is provided with a flat surface and a curved surface. The flat position of the rubber arc plate 111 is fixedly connected to the lower end of the push plate 11, the curved surface position of the rubber arc plate 111 is adapted to fit the inner wall of the air supply pipe 5, and the outer surface of the rubber arc plate 111 is movably connected to the inner surface of the air intake filter plate 51.

[0049] When the push plate 11 generates a pushing and pulling effect when connected to the connecting screw 10, the rubber arc plate 111 and the inner surface of the air intake filter plate 51 are scraped back and forth. The reason why the rubber arc plate 111 is set to rubber material is to ensure the sealing of the air supply pipe 5, and at the same time achieve auxiliary cleaning of the air intake filter plate 51 to prevent air intake blockage, further solving the problem of incomplete waste gas treatment caused by the difficulty in separating solid particles in the existing VOCs waste gas, and can achieve effective treatment of VOCs waste gas.

[0050] Example 7

[0051] A VOCs waste gas treatment device and system. As mentioned above, the system of the VOCs waste gas treatment device includes a controller installed on the outside of the waste gas treatment device body 1 and a sensor installed on the lower side wall of the waste gas treatment device body 1. The signal connection end of the controller is connected to an actuator. The actuator includes an air inlet and outlet system and a spray system. The sensor senses the density of solid particles accumulated at the bottom of the inner filter cartridge 2, monitors it in real time and reflects it to the actuator, and the output end of the actuator is fixedly connected to a self-cleaning mechanism.

[0052] During actual use, first, sufficient reaction liquid for solid reduction is poured into the liquid storage tank 4, and the air inlet port of the air supply pipe 5 is tightly connected to the exhaust gas duct. When the VOCs exhaust gas is input into the exhaust gas treatment equipment body 1 through the air inlet end of the air supply pipe 5, the exhaust gas is introduced into the air supply pipe 5 through multiple groups of air inlet holes 61 and air guide column 1 62, and at this time, the air guide column 2 81 corresponding to the sealing plug column 1 63 on the inner side of the fixed sealing plate 6 is separated from it, and the sealing plug column 2 82 is separated from the air guide column 1 62, and at this time, the return spring 7 is affected by the pulling force of the movable sealing plate 8 and is stretched and deformed, and the introduced VOCs exhaust gas is ejected outward through the jet elbow 9, and at this time, the push plate 11 and the ejector pin 12 are affected by the top thrust of the movable sealing plate 8 and move toward the side of the spray control switch 14, and the lower side of the push plate 11 is staggered with the air intake filter plate 51. At this time, the VOCs exhaust gas introduced passes through the air intake The filter plate 51 enters the interior of the inner filter cartridge 2, and the ejector pin 12 is always in conflict with the spray control switch 14. At this time, the spray solid reduction mechanism is triggered, and the liquid pump 15 is turned on to automatically extract the solid reduction liquid inside the liquid storage tank 4. The liquid is stored inside the conical liquid storage bucket 18 and the hexagonal plate 19 through the liquid delivery pipe 17. At this time, it is sprayed out through multiple sets of liquid delivery elbows 191. Under the action of the liquid delivery elbows 191, a reverse injection force is given to the spray storage plate 192 to ensure that the spray storage plate 192 drives the hexagonal plate 19 to rotate as a whole, and at this time, the rotating seat 16 assists the hexagonal plate 19 to rotate as a whole, ensuring that the drainage hole and the spray bucket 20 mix the solid particles in the exhaust gas inside the inner filter cartridge 2 to complete the dust reduction. The filtered gas is discharged through the exhaust pipe 28, and the sprayed solid and liquid fall into the waste hopper 27 for storage. Finally, the waste is cleaned by opening and closing the gate 271.
