[0018] 2. This invention provides a VOCs organic waste gas treatment device, which achieves deep treatment of VOCs organic waste gas through a multi-stage synergistic purification structure. First, most of the organic matter is decomposed by combustion, and then primary filtration is carried out through fiber filter cartridges. Combined with the water film formed by the warm absorption liquid and the staggered water curtain, dual absorption is carried out, which greatly improves the capture and removal effect of organic pollutants and fine particulate matter, ensuring that the waste gas can stably meet the emission requirements after purification. It is suitable for the treatment of organic waste gas under various complex working conditions.
[0019] 3. This invention provides a VOCs organic waste gas treatment device, which adopts an automated dust removal design without external power. It relies on the buoyancy of accumulated water to control intermittent drainage and uses water flow impact to drive a vibration mechanism to achieve gentle dust removal of the filter cartridge. This can effectively prevent filter cartridge blockage and ensure long-term stable operation, without damaging the filter cartridge structure and extending its service life. At the same time, the overall structure is reliable in operation, reducing the frequency of manual maintenance and the probability of equipment failure, and improving the overall service life and stability of the device.
[0020] 4. This invention provides a VOCs organic waste gas treatment device that integrates waste heat utilization, water recycling and tail gas demisting functions.

[0034] Specific implementation examples are given below.
[0035] Please see Figure 1 - Figure 12 This invention provides a technical solution: a VOCs organic waste gas treatment device, including a device shell 1, with support legs 2 fixedly connected to the four corners of the lower end of the device shell 1, a filter separation component 5 jointly arranged at the lower end of the device shell 1 and the upper part of the inner cavity, an exhaust demisting mechanism 4 fixedly installed on one side of the device shell 1, an intake combustion mechanism 3 installed on one side of the filter separation component 5, and a vibration component 6 arranged in the inner cavity of the device shell 1 below the filter separation component 5. The intake combustion mechanism 3 includes a low-temperature burner 31 fixedly installed on one side of the filter separation component 5, the intake end of the low-temperature burner 31 is connected to the VOCs organic waste gas emission pipe, the exhaust end of the low-temperature burner 31 is fixedly connected to an intake pipe 32, a plurality of heat exchange plates 33 are arranged on the outside of the intake pipe 32, and the top end of the intake pipe 32 extends to the bottom of the inner cavity of the device shell 1.
[0036] By setting an air intake combustion mechanism 3 on one side of the device casing 1, the low-temperature burner 31 is used to pre-treat VOCs organic waste gas, which can efficiently decompose most organic pollutants. The air intake pipe 32, together with the heat exchange plate 33, can transfer the combustion waste heat to the inside of the water tank 51, realize heat energy recovery and utilization, reduce the overall energy consumption of the device, and at the same time, can appropriately increase the temperature of the solvent inside the water tank 51, thereby improving the solvent activity and improving the treatment efficiency of the subsequent absorption and purification process.
[0037] like Figure 2 , Figure 3 and Figure 4 As shown, the filtration and separation assembly 5 includes a water tank 51 fixedly connected to the lower end of the device housing 1, an air inlet pipe 32 passing through the interior of the water tank 51, and all heat exchange plates 33 located at the lower position inside the water tank 51. A water circulation mechanism 52 is provided in the inner cavity of the water tank 51, a water curtain mechanism 53 is provided on the upper part of the inner surface of the device housing 1, and a filtration mechanism 54 is provided on the inner surface of the device housing 1 below the water curtain mechanism 53.
[0038] By fixing the filter separation component 5 to the device housing 1, the water tank 51 provides storage space for water recycling, the water circulation mechanism 52 can realize the circulation and transportation of the absorbent liquid, the water curtain mechanism 53 can form a multi-layer water curtain to wash the exhaust gas, and the filter mechanism 54 can intercept and adsorb particulate matter and residual organic matter in the exhaust gas. The multi-stage cooperation realizes the deep purification of VOCs organic waste gas.
[0039] The water circulation mechanism 52 includes an inlet pipe 523 that penetrates one side of the inner surface of the water tank 51 and extends to one side of the inner surface of the device housing 1 and is fixedly connected. One end of the inlet pipe 523 is located in the inner cavity of the water tank 51 and is fixedly connected to a water pump 522. A partition 521 is movably installed on one side of the water tank 51 and extends to one side of the inner surface of the water tank 51. A drain pipe 524 is fixedly connected on one side of the inner surface of the water tank 51 and extends to one side of the inner surface of the device housing 1.
[0040] By setting a water circulation mechanism 52 inside the water tank 51, the water pump 522 provides power for the flow of the absorbent liquid, the inlet pipe 523 transports the warm absorbent liquid to the water curtain mechanism 53, the baffle 521 can block and filter impurities in the absorbent liquid, and the drain pipe 524 can return the circulated absorbent liquid to the water tank 51 for storage, ensuring the continuous and stable circulation of the absorbent liquid and ensuring the utilization rate of the absorbent liquid.
[0041] like Figure 5As shown, the water curtain mechanism 53 includes a first inclined plate 531 fixedly connected to the inner surface of the device housing 1. A second inclined plate 534 is fixedly connected to the inner surface of the device housing 1 below the first inclined plate 531. An overflow frame 532 connected to the inner surface of the water inlet pipe 523 is fixedly connected to the upper end of the first inclined plate 531. An overflow hole 533 is opened at the upper part of one end of the overflow frame 532. A third inclined plate 535 is fixedly connected to the inner surface of the device housing 1 below the second inclined plate 534. An arc plate 536 is fixedly connected to the left end of the third inclined plate 535.
[0042] By setting a water curtain mechanism 53 inside the outer casing 1 of the device, the inclined plates 531, 534 and 535 are staggered to guide the exhaust gas to flow in an S-shape, prolonging the contact time between the exhaust gas and the water curtain. The overflow frame 532 and the overflow hole 533 form a uniform water curtain, and the arc plate 536 guides the water flow back, thereby improving the gas-liquid contact area and the absorption effect of organic waste gas.
[0043] like Figure 6 and Figure 7 As shown, the filtration mechanism 54 includes a limiting groove 541 formed on one side of the inner surface of the device housing 1. A limiting block 542 is slidably connected to the inner surface of the limiting groove 541. A lead screw 543 is rotatably connected to the inside of the limiting groove 541 and extends to the right end of the device housing 1. The outer surface of the lead screw 543 is slidably connected to the limiting block 542. A concave frame 545 is fixedly connected to one side of the limiting block 542. A sponge block 547 is fixedly connected to the inner surface of the concave frame 545. A filter plate 546 that is in close contact with the bottom end of the sponge block 547 is fixedly connected to the middle of the inner surface of the device housing 1. A connecting hose 548 is fixedly connected to the lower middle side of the inner surface of the overflow frame 532 and extends to the upper part of the inner surface of the concave frame 545. One end of the lead screw 543 is rotatably connected to the left side of the inner surface of the limiting groove 541. The other end of the lead screw 543 is fixedly connected to a motor 544 that is fixedly connected to the right end of the device housing 1.
[0044] It should be noted that the lead screw 543 is a reciprocating lead screw. The motor 544 can drive the lead screw 543 to rotate in one direction, which in turn causes the concave frame 545 to slide back and forth. The unidirectional rotation of the lead screw 543 can drive the rotating disk 42 to rotate continuously and stably in one direction through the pulley group 55, thus ensuring the defogging effect.
[0045] By setting a filter mechanism 54 inside the housing 1 of the device, the motor 544 drives the lead screw 543 to move the limit block 542 back and forth. The concave frame 545 and the sponge block 547 move synchronously to form a uniform water film on the surface of the filter plate 546. The connecting hose 548 continuously supplies water to the sponge block 547. The water film can efficiently capture residual pollutants in the exhaust gas, further improving the purification accuracy.
[0046] like Figure 8As shown, the exhaust demisting mechanism 4 includes a perforated cover 41 fixedly connected to the upper middle side of one side of the device housing 1. The middle of the perforated cover 41 extends through and to the right side of the inner surface of the perforated cover 41, and a rotating rod is rotatably connected to the right end of the device housing 1. One end of the rotating rod is fixedly connected to a rotating disk 42. A plurality of locking frames 43 are fixedly connected to one side of the rotating disk 42. A rectangular frame 44 is locked inside the locking frame 43. A water-absorbing gauze 45 is fixedly connected inside the rectangular frame 44. One end of the rotating rod is fixedly connected to a pulley group 55 fixedly connected to one end of the lead screw 543. An air intake pipe 46 is fixedly connected to the upper middle side of the upper part of the perforated cover 41 extending through and to the upper side of the inner surface of the device housing 1. A recovery pipe 47 extending through and to the upper part of the water tank 51 is fixedly connected to the middle of the bottom of the perforated cover 41.
[0047] By setting an exhaust demisting mechanism 4 on one side of the device housing 1, the pulley group 55 drives the rotating disk 42 and the water-absorbing gauze 45 to rotate, centrifugally dehydrate and adsorb demisting the purified exhaust gas. The suction pipe 46 guides the exhaust gas flow, and the recovery pipe 47 returns the removed water to the water tank 51, avoiding secondary pollution caused by water in the exhaust gas, and realizing the recycling of water resources.
[0048] like Figure 3 and Figure 9 As shown, the vibration assembly 6 includes a fixed plate 61 fixedly connected to the inner surface of the device housing 1. Several fiber filter cartridges 62 are fixedly connected to the inner surface of the fixed plate 61. An inclined plate 64 is fixedly connected to the upper end of the fixed plate 61. A drain pipe 63 is fixedly connected to the lower middle part of the inner surface of the inclined plate 64 and extends to the upper part of the inner surface of the water tank 51. A buoyancy mechanism 65 is provided on the lower part of the inner surface of the inclined plate 64. A blocking mechanism 66 is provided on the inner surface of the drain pipe 63. A vibration mechanism 67 is provided on the lower part of the inner surface of the device housing 1.
[0049] By setting a vibration component 6 inside the housing 1 of the device, the fixed plate 61 provides a stable installation base for the fiber filter cartridge 62. The fiber filter cartridge 62 performs primary filtration on the pre-treated waste gas. The inclined plate 64 collects the circulating water flow, and the drain pipe 63 guides the water flow back. The buoyancy mechanism 65 works with the vibration mechanism 67 to realize automatic dust removal of the filter cartridge, prevent filter cartridge blockage and ensure filtration efficiency.
[0050] like Figure 10 As shown, the buoyancy mechanism 65 includes a concave block 651 fixedly connected to the lower part of the inner surface of the inclined plate 64. A rotating cover 652 is rotatably connected inside the concave block 651. A pull rope 653 is fixedly connected to the top of the rotating cover 652. A buoyancy ball 654 is fixedly connected to the upper end of the pull rope 653.
[0051] By setting a buoyancy mechanism 65 at the lower part of the inclined plate 64, the concave block 651 provides rotational support for the rotating cover 652. The buoyancy ball 654 pulls the rope 653 to control the opening and closing of the rotating cover 652 as the water level rises and falls, realizing intermittent automatic drainage without external power drive, thus improving the degree of automation of the device.
[0052] like Figure 12 As shown, the blocking mechanism 66 includes a round rod 661 fixedly connected to the inner surface of the drain pipe 63. The top end of the round rod 661 extends through and to the lower end of the round rod 661, where a flow channel 662 is provided. An arc-shaped block 663 is fixedly connected to the lower part of the inner surface of the flow channel 662.
[0053] By setting a blocking mechanism 66 inside the second drain pipe 63, the round rod 661 cooperates with the flow channel 662 to narrow the water flow channel and increase the water flow speed. The arc block 663 changes the direction of water jet and accurately impacts the power component of the vibration mechanism 67, providing a stable power source for vibration cleaning. The structure is simple and the operation is reliable.
[0054] like Figure 11 As shown, the vibration mechanism 67 includes a water impeller 671 that passes through the interior of the second drain pipe 63 and extends to the right side of the outer surface of the second drain pipe 63 and is rotatably connected. The water impeller 671 is located below the round rod 661. A fixing block 673 that is rotatably connected to the outer surface of the water impeller 671 is fixedly connected inside the device housing 1. A cam block 672 is fixedly connected to the outer surface of the water impeller 671. Springs 674 are symmetrically fixedly connected to the bottom of the device housing 1. A connecting rod 675 is fixedly connected to the upper end of the springs 674 on the same side. A rectangular plate 676 is fixedly connected to the side of the outer surfaces of the two connecting rods 675 that are close to each other.
[0055] By setting a vibration mechanism 67 at the lower part of the device housing 1, the water impeller 671 is driven by the water flow to rotate the cam block 672. The cam block 672 intermittently pushes the rectangular plate 676 and the connecting rod 675. The spring 674 provides the resetting power for the connecting rod 675, so as to achieve gentle knocking and dust removal of the fiber filter cartridge 62 without damaging the filter cartridge structure and extending the service life of the filter cartridge.
[0056] The working principle of this invention is as follows: When in use, VOCs organic waste gas first enters the low-temperature burner 31 in the air intake combustion mechanism 3 for low-temperature catalytic combustion pretreatment, which effectively decomposes most of the organic pollutants in the waste gas. The waste heat generated by combustion is transferred to the inside of the water tank 51 through the air intake pipe 32 and the heat exchange plate 33 to heat the absorption solvent in the water tank 51 to improve the solvent activity and absorption efficiency.
[0057] The preheated exhaust gas is transported through the inlet pipe 32 to the bottom of the device housing 1, and then passes upward through the fiber filter cartridge 62 in the vibration assembly 6. The fiber filter cartridge 62 performs primary filtration of particulate matter and combustion residue impurities in the exhaust gas. The fixed plate 61 provides stable support for the fiber filter cartridge 62. The inclined plate 64 collects the circulating water flowing down inside the device. When the water accumulates to a certain height, the buoyancy ball 654 in the buoyancy mechanism 65 rises with the water level, and drives the rotating cover 652 to rotate around the concave block 651 through the pull rope 653. When the water flows into the drain pipe 63, the round rod 661 in the blocking mechanism 66 and the flow channel 662 narrow the water flow channel and accelerate the flow rate. The arc block 663 changes the direction of water flow and impacts the water impeller 671 in the vibration mechanism 67. The water impeller 671 rotates under the support of the fixed block 673 and drives the cam block 672 to rotate. The cam block 672 intermittently pushes the rectangular plate 676 and the connecting rod 675. The spring 674 provides the reset power for the connecting rod 675, realizing the gentle tapping and dust removal of the fiber filter cartridge 62 and avoiding filter cartridge blockage.
[0058] The exhaust gas, having completed primary filtration, continues to move upward. The water pump 522 in the water circulation mechanism 52 transports the warm absorption liquid in the water tank 51 through the inlet pipe 523 to the overflow frame 532 in the water curtain mechanism 53. The absorption liquid overflows from the overflow hole 533, forming an interlaced water curtain on the surfaces of inclined plate 1 531, inclined plate 2 534, and inclined plate 3 535. The arc plate 536 guides the water flow back to the water tank 51. The partition plate 521 filters impurities in the circulating absorption liquid. At the same time, the motor 544 in the filtration mechanism 54 drives the lead screw 543 to rotate, causing the limit block 542 to move back and forth along the limit groove 541. The concave frame 545 and the sponge block 547 move synchronously. The connecting hose 548 continuously supplies water to the sponge block 547. The sponge block 547 coats the surface of the filter plate 546 to form a uniform water film. The exhaust gas passes through the water film and multiple layers of water curtain in an S-shape, and the residual organic pollutants and fine particulate matter are fully captured and absorbed.
[0059] The exhaust gas that has undergone deep purification enters the perforated hood 41 through the suction pipe 46 in the exhaust demisting mechanism 4. The pulley group 55 drives the rotating disk 42 and the positioning frame 43 to rotate. The water-absorbing gauze 45 in the rectangular frame 44 centrifuges and dehydrates the exhaust gas and adsorbs and demistates it, removing moisture and mist droplets from the exhaust gas. The removed moisture flows back to the water tank 51 through the recovery pipe 47 to realize the recycling of water resources. Finally, the dry and clean gas is discharged through the perforated hole of the perforated hood 41, completing the entire purification and treatment process of VOCs organic waste gas.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
