Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a high-efficiency, low-maintenance printing waste gas purification and treatment system. Background Art

[0002] The printing industry produces a large amount of waste gas during the production process. These waste gases contain harmful substances and cause harm to the environment and human health. At present, there are some printing waste gas purification equipment on the market, but they have shortcomings in treatment efficiency, maintenance costs, secondary pollution, etc.

[0003] For example, a Chinese patent (publication number: CN218166265U) discloses a printing waste gas purification and treatment system, which includes a positive pressure studio, a printing operation room, a bag dust collector, a filter element filter and a high-temperature oxidation device in sequence. The positive pressure studio is provided with a positive pressure fresh air inlet end, and a return air duct is connected between the air outlet end of the filter element filter and the printing operation room; the bag dust collector and the filter element filter are also respectively connected to a diversion air duct, and the air outlet end of the diversion air duct is connected to the high-temperature oxidation device; the air purified by the high-temperature oxidation device is discharged to the outside. The utility model has a very good purification effect on printing waste gas, can maintain purification activity for a long time, can replenish the positive pressure studio with fresh air from the outside in real time, can form a gas external circulation and a gas internal circulation, most of the gas can flow back to the printing operation room, and a small part of the gas is discharged after purification by the high-temperature oxidation device, thereby improving the purification efficiency and purification effect and reducing the energy consumption of the high-temperature oxidation equipment.

[0004] The above-mentioned printing waste gas purification and treatment system still has certain shortcomings. The positive pressure studio supplements fresh air from the outside to form external gas circulation and internal gas circulation. Most of the gas can flow back to the printing operation room, and a small part of the gas is purified by high-temperature oxidation equipment and then discharged. Although the waste gas can be purified, some harmful substances will still remain in the waste gas during the treatment process. It is difficult to convert harmful substances into harmless substances and discharge them, which will have an impact on the environment. Therefore, this application proposes a high-efficiency, low-maintenance printing waste gas purification and treatment system to solve the above problems. Utility Model Content

[0008] By adopting this technical solution, the exhaust gas is filtered through the filtering mechanism to remove organic solvents and some harmful substances in the exhaust gas, and the harmful substances in the treated exhaust gas are converted into harmless substances through the combustion mechanism.

[0009] Furthermore, the filter assembly includes multiple telescopic rods fixed on the upper surface of the horizontal plate, a first spring sleeved on the outer surface of the telescopic rods, a filter plate fixed on the upper surface of the multiple telescopic rods, and activated carbon placed on the upper surface of the filter plate.

[0011] Furthermore, a second fan and a monitor are fixed to the upper surface of the combustion chamber, a first connecting pipe is fixed to the input end of the second fan, and a second connecting pipe is fixed to the output end of the second fan.

[0013] Furthermore, the upper surface of the first spring is fixed to the lower surface of the filter plate, and the lower surface of the first spring is fixed to the upper surface of the transverse plate.

[0014] By adopting this technical solution, the filter plate and the activated carbon are moved up and down by the first spring. The movement of the activated carbon increases the contact area with the exhaust gas, which is beneficial to the filtering effect of the exhaust gas.

[0015] Furthermore, the upper surface of the cam abuts against the lower surface of the filter plate, and the filter plate is slidably connected to the inner cavity wall of the purification chamber.

[0016] By adopting this technical solution, the filter plate is pushed to move by the cam, and the filter plate slides in the clean room, thereby increasing stability during movement.

[0024] 1. This high-efficiency, low-maintenance printing waste gas purification and treatment system uses a filtering mechanism. The motor drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear, the rotating rod and multiple cams to rotate. The cam pushes the filter plate and activated carbon upward together, increasing the contact area between the activated carbon and the waste gas. When the cam moves away from the filter plate, the filter plate resets, and the filter plate and activated carbon move downward. The up and down movement of the filter plate and activated carbon increases the contact area between the activated carbon and the waste gas, thereby improving the filtering effect.

[0025] 2. This high-efficiency, low-maintenance printing waste gas purification and treatment system uses a combustion mechanism to pull the pull rod, drive the pressure plate, the block and the limit plate and squeeze the second spring to insert the catalytic plate into the through hole.

The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0047] The working principle of the above embodiment is:

[0048] (1) When the exhaust gas enters the purification chamber 4, the motor 501 is started, and the motor 501 drives the first bevel gear 502 to rotate. The first bevel gear 502 drives the second bevel gear 503 to rotate together. The second bevel gear 503 drives the rotating rod 505 and multiple cams 506 to rotate together. The filter plate 509 is pushed upward by the cam 506, and the activated carbon 510 is pushed upward by the filter plate 509, so that the contact area between the activated carbon 510 and the exhaust gas is increased. When the cam 506 is away from the bottom of the filter plate 509, the filter plate 509 is reset under the action of the first spring 508, so that the filter plate 509 and the activated carbon 510 move downward. Through the up and down movement of the filter plate 509 and the activated carbon 510, the contact area between the activated carbon 510 and the exhaust gas is increased, thereby improving the filtering effect.

At this time, the catalytic plate 302 is inserted into the through hole 301, so that the baffle 303 abuts against the right side of the combustion chamber 2. Release the pull rod, and the pressure plate 309 is reset under the action of the second spring 308, driving the block 310 and the limit plate 312 to move together, so that the block 310 is stuck in the inside of the card slot 311, and the limit plate 312 is fitted with the baffle 303, fixing the catalytic plate 302. When the exhaust gas passes through the catalytic plate 302, it will pass through the fire barrier plate 304 into the upper part of the inner cavity of the combustion chamber 2, and be burned by the burner 305 to remove harmful substances in the exhaust gas and improve the purification effect of the exhaust gas.
