Description

Technical Field

[0002] When textiles are heat treated and finalized, the dye auxiliaries, coating auxiliaries, etc. from the previous treatment process will be heated, thereby generating smoke, which contains a large amount of VOCs (volatile organic compounds). If the exhaust gas is discharged without treatment, it will pose a great threat to the environment and easily cause harm to the health of the operators. In order to treat the discharged exhaust gas, the exhaust gas pipe is usually connected to a dedicated exhaust component for treatment before discharge.

A filter component is rotatably arranged in the cylinder, and the filter component includes a filter net. A spray component is arranged on one side of the filter component. The filter component is used to separate the waste gas and impurities in the waste gas during the rotation process, and the spray component is used to rinse the filter net. After the waste gas and the impurities in the waste gas are separated, the filtered waste gas is discharged, and the working efficiency is high and the filtering effect is good.

[0004] Although the existing printing and dyeing waste gas exhaust assembly can effectively treat the dust and volatile organic compounds in the waste gas, after long-term use, the module inside it for adsorbing volatile organic compounds will lose the effect of adsorbing volatile organic compounds due to adsorption saturation. At this time, it is necessary to remove the adsorption module and install a new adsorption module. This process is cumbersome, time-consuming and labor-intensive, and at the same time, it is necessary to shut down the printing and dyeing device to stop the smoke from continuing to enter the exhaust assembly before the operation can be carried out. Therefore, in view of the above problems, a printing and dyeing waste gas exhaust assembly with low desorption difficulty is proposed. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figure 1-Figure 8As shown, a printing and dyeing waste gas exhaust component with low desorption difficulty includes a fume treatment chamber 1; an air inlet 2 is fixedly connected to the left side of the fume treatment chamber 1, an exhaust port 3 is fixedly connected to the right side of the fume treatment chamber 1, an induced draft fan 4 is fixedly connected to the top of the exhaust port 3, a desorption chamber 5 is fixedly connected to the bottom end of the fume treatment chamber 1, and waste gas treatment mechanisms are arranged inside the fume treatment chamber 1 and the desorption chamber 5;

The exhaust gas filtration module includes a coarse filter plate 41, and the coarse filter plate 41 is fixedly connected to the inner wall of the flue gas treatment chamber 1 near the left side. A fine filter plate 42 is arranged on the right side of the coarse filter plate 41, and the fine filter plate 42 is also fixedly connected to the On the inner wall of the flue gas treatment chamber 1, a first support frame 44 is provided near the center of the flue gas treatment chamber 1, a first activated carbon adsorption plate 45 is fixedly connected to the inner wall of the first support frame 44, a tail adsorption plate 43 is fixedly connected near the right side of the flue gas treatment chamber 1, mesh holes are provided on the coarse filter plate 41 and the fine filter plate 42, the mesh hole diameter provided on the fine filter plate 42 is smaller than the mesh hole diameter provided on the coarse filter plate 41, and the coarse filter plate 41 and the fine filter plate 42 are both designed to be inclined;

[0034] During operation, the flue gas enters the interior of the flue gas treatment chamber 1 through the air inlet 2, and a negative pressure is formed in the flue gas treatment chamber 1 through the induced draft fan 4, so that the flue gas flows to the exhaust port 3, and firstly, large particles and dust in the flue gas are filtered through the coarse filter plate 41, and then smaller particles and dust in the flue gas are filtered through the fine filter plate 42, and then the organic volatiles in the flue gas are adsorbed by the first activated carbon adsorption plate 45 or the second activated carbon adsorption plate 57, and finally the residual organic volatiles in the flue gas are adsorbed again by the tail adsorption plate 43, so that the flue gas meets the emission standards, and the treated flue gas is discharged through the exhaust port 3 and the induced draft fan 4, and the blocked particles are automatically moved downward and accumulated at the bottom by the inclined coarse filter plate 41 and the fine filter plate 42 under the action of the blowing of the flue gas and gravity, which can effectively avoid the overall blockage of the coarse filter plate 41 and the fine filter plate 42, and at the same time, the particles blocked by the coarse filter plate 41 and the fine filter plate 42 can be conveniently cleaned.

[0035] Furthermore, the replacement and desorption module includes a movable sealing component, a transmission replacement component and a baffle component. The movable sealing component is arranged at the bottom end of the flue gas treatment chamber 1, the transmission replacement component is arranged between the flue gas treatment chamber 1 and the desorption chamber 5, the baffle component is arranged at the bottom end of the transmission replacement component, the movable sealing component includes an isolation plate 47, the bottom end of the isolation plate 47 is provided with an inclined surface, and the bottom end of the isolation plate 47 is glued with a sealing gasket 48, the sealing gasket 48 is made of silicone rubber, one side of the isolation plate 47 is fixedly connected with a first slider 49, the first slider 49 is slidably connected to the outside of the first guide rod 50, the first guide rod 50 is fixedly connected to the inside of the first slide groove 51, the first slide groove 51 is arranged at the bottom end of the inner wall of the flue gas treatment chamber 1, the outside of the first guide rod 50 is wrapped with a first spring 52, the side of the first spring 52 close to the first slider 49 is fixedly connected to the first slider 49, and the first spring 52 The side away from the first slider 49 is fixedly connected to the inner wall of the first slide groove 51, and the transmission replacement assembly includes a first rack 53, the first rack 53 is fixedly connected to the front and rear ends of the first support frame 44, and the first rack 53 is meshed with a transmission gear 54, the transmission gear 54 is rotatably connected to the inner wall of the detachment bin 5, and the transmission gear 54 is also meshed with a second rack 55, the second rack 55 is fixedly connected to the front and rear ends of the second support frame 56, and a second activated carbon adsorption plate 57 is fixedly connected to the inner wall of the second support frame 56. The second support frame 56 and the side of the top of the first support frame 44 close to the isolation plate 47 are arc-shaped, and the second support frame 56 and the side of the first support frame 44 close to the isolation plate 47 are also rotatably connected to the drag reduction wheel 46, and the transmission gear 54 is fixedly connected to the knob 74, and the knob 74 passes through the detachment bin 5 and extends to the outside of the detachment bin 5;

[0036] During operation, when the first activated carbon adsorption plate 45 and the second activated carbon adsorption plate 57 are to be replaced, the knob 74 is first turned to drive the fixedly connected transmission gear 54 to rotate synchronously, so that the first rack 53 and the second rack 55 meshing with the transmission gear 54 move synchronously in opposite directions, so that the first activated carbon adsorption plate 45 and the first supporting frame 44 enter downward into the desorption chamber 5, and the second supporting frame 56 and the second activated carbon adsorption plate 57 enter upward into the flue gas treatment chamber 1. When the first activated carbon adsorption plate 45 has not yet completely entered into the desorption chamber 5 and the second activated carbon adsorption plate 57 has not yet completely entered into the flue gas treatment chamber 1, the movable plate 58 is no longer squeezed. At this time, the movable plate 58 moves upward under the action of the restoring force of the second spring 62 and drives the connecting frame 66 to move upward synchronously, so that the driving wheel 67 fixedly connected to the connecting frame 66 moves synchronously, and then the driving wheel 67 releases the squeezing of the drainage baffle 68, so that the second slider 70 is under the action of the restoring force of the third spring 73. The drainage baffle 68 is driven downward to move to the original position, and the obstruction of the drainage port 69 is released, so that the steam containing organic volatiles condensed in the desorption chamber 5 is discharged from the drainage port 69. When the first rack 53 contacts the movable plate 58 with the movement of the first activated carbon adsorption plate 45, the movable plate 58 is squeezed again. At this time, the movable plate 58 moves downward under the action of the squeezing force and pulls the second spring 62 to produce elastic deformation. In the process of the movable plate 58 moving downward, the steam baffle 64 is also driven to move synchronously through the fixedly connected connecting rod 63, so that the steam baffle 64 removes the obstruction of the steam inlet 65, so that the steam pipe connected to the steam inlet 65 transports steam to the interior of the desorption chamber 5, and the organic volatiles adsorbed in the first activated carbon adsorption plate 45 or the second activated carbon adsorption plate 57 are evaporated and desorbed by steam. When the steam inlet 65 is opened for the first time, the steam is continuously introduced for 3 hours, then stopped and the pressure is maintained for 6 hours, and then the pressure is released. Thereafter, steam is introduced for 30 minutes every 24 hours, the pressure is maintained for 2 hours, and then the pressure is released;

[0037] When the second support frame 56 and the second activated carbon adsorption plate 57 move upward into the interior of the flue gas treatment chamber 1, the drag reduction wheel 46 connected to the top of the second support frame 56 pushes the inclined surface at the bottom of the isolation plate 47 to move the isolation plate 47 away from the second support frame 56, thereby removing the obstruction of the second support frame 56 and the second activated carbon adsorption plate 57, so that the second support frame 56 and the second activated carbon adsorption plate 57 can smoothly enter the interior of the flue gas treatment chamber 1, and when the isolation plate 47 moves in the direction away from the second support frame 56, it drives the fixedly connected first slider 49 to synchronously move in the first slide groove 51 , and squeezes the first spring 52 to cause elastic deformation of the first spring 52. The restoring force of the first spring 52 plays a role in keeping the isolation plate 47 always in close contact with the second support frame 56 and the second activated carbon adsorption plate 57, thereby separating the flue gas treatment chamber 1 and the desorption chamber 5. When the isolation plate 47 moves, the sealing pad 48 glued to the bottom end is used to isolate the flue gas treatment chamber 1 and the desorption chamber 5, so that the flue gas treatment chamber 1 and the desorption chamber 5 are isolated and sealed from each other. The same is true when the first support frame 44 and the first activated carbon adsorption plate 45 enter the interior of the flue gas treatment chamber 1.

[0038] Furthermore, the baffle assembly includes a movable plate 58, which is arranged inside a movable groove 59, which is opened on the front and rear sides of the inner wall of the detachment bin 5, and a guide rail 60 is fixedly connected to the inner wall of the movable groove 59, and the guide rail 60 is slidably connected to the movable plate 58. The movable plate 58 is also sleeved on the outer side of a second guide rod 61, and the second guide rod 61 is fixedly connected to the inside of the movable groove 59. A second spring 62 is also wound around the outer side of the second guide rod 61. The right side of the movable plate 58 is fixedly connected to a connecting rod 63, and the right side of the connecting rod 63 is fixedly connected to a steam baffle 64, which cooperates with a steam inlet 65, and the steam inlet 65 is opened on the right side of the detachment bin 5. The opposite sides of the two sets of movable plates 58 are fixedly connected to a connecting frame 66, and the bottom end of the connecting frame 66 is rotatably connected to a top driving wheel 67 , the top wheel 67 abuts against the drainage baffle 68, the bottom end of the drainage baffle 68 is fixedly connected to the second slider 70, the bottom end of the detachment bin 5 is provided with a drainage port 69, and the inner wall of the detachment bin 5 is provided with an inclined surface near the bottom end, the second slider 70 is slidably connected to the outside of the third guide rod 71, the third guide rod 71 is fixedly connected to the inside of the second slide groove 72, the second slide groove 72 is provided at the bottom end of the inner wall of the detachment bin 5, and the outside of the second slide groove 72 is also wound with a third spring 73, the top end of the second spring 62 is fixedly connected to the inner wall of the movable groove 59, the bottom end of the second spring 62 is fixedly connected to the top end of the movable plate 58, the side of the third spring 73 close to the second slider 70 is fixedly connected to the second slider 70, and the side of the third spring 73 away from the second slider 70 is fixedly connected to the inner wall of the second slide groove 72;

[0039] When working, when the movable plate 58 moves downward, it drives the fixedly connected connecting frame 66 to move downward synchronously, so that the driving wheel 67 at the bottom end of the connecting frame 66 drives the drainage baffle 68 to move, so that the drainage baffle 68 drives the fixedly connected second slider 70 to move synchronously, and the second slider 70 pulls the third spring 73 to produce elastic deformation when moving. When the movable plate 58 moves downward to the limit, the driving wheel 67 also drives the drainage baffle 68 to move synchronously to the limit to block the drainage port 69, so as to prevent the steam from entering the desorption chamber 5. Steam leaks from the drain port 69. The front and rear sides of the top of the drain baffle 68 are both provided with inclined surfaces. The inclined surface on the front side allows the drain baffle 68 to move when it is squeezed. At the same time, the inclined surfaces on the front and rear sides can also make the steam condensed on the drain baffle 68 slide down the inclined surfaces. The inclined surfaces on both sides of the bottom end of the inner wall of the desorption bin 5 can guide the condensed steam to the center position of the bottom end of the desorption bin 5, so that it can be smoothly discharged from the desorption bin 5 through the drain port 69.
