Description

Technical Field

[0001] The present invention belongs to the technical field of organic waste gas treatment, and in particular relates to a multi-stage treatment device for extraction of printing and dyeing organic waste gas. Background Art

[0002] During the production process, printing and dyeing equipment emits organic waste gas containing large amounts of harmful substances such as benzene, alcohols, and aromatic hydrocarbons. These waste gases are not only toxic, irritating, and carcinogenic, but also react chemically with atmospheric NOx under sunlight to form secondary pollutants (such as ozone), thereby increasing the surface concentration of smog and ozone. Therefore, a multi-stage extraction and treatment device for printing and dyeing organic waste gas is needed to purify the printing and dyeing organic waste gas.

[0003] After searching, the prior art publication number is CN115193225A, which is a VOCs organic waste gas treatment device; the device adsorbs the waste gas through the activated carbon filter element in the first air inlet cylinder, and then the waste gas enters the spray barrel through the air inlet pipe, and the organic solvent at the bottom of the spray barrel performs the initial washing of the waste gas, and at the same time controls the front and rear sliding of the push frame so that the front and rear spray pipes alternately spray the organic solvent, so that the organic solvent continuously sprays the VOCs organic waste gas; the washed waste gas is discharged from the top of the spray barrel; at the same time, the device is provided with a cleaning mechanism for cleaning the activated carbon filter element; but the height of the spray barrel is limited and there is no obstruction inside, so the waste gas will quickly rise to above the spray pipe in the spray barrel, resulting in pollutants remaining in the waste gas; and the dust remaining in the waste gas will enter the washing liquid, which will not only reduce the purity of the washing liquid and affect the washing effect of the washing liquid on the waste gas, but may also cause the spray pipe to be blocked, affecting the normal operation of the device;

[0004] After searching, the prior art publication number CN117771890A discloses a volatile organic waste gas scrubber, its preparation method, and its use method. The invention comprises the following ingredients by mass percentage: 0.5% to 10% liquid paraffin, 0.05% to 10% ethylene glycol, 0.5% to 5% emulsifier, 0.1% to 2% defoamer, 0.5% to 10% sodium citrate, 5% to 20% sodium carbonate, 0.5% to 5% surfactant, and the remainder is deionized water. The scrubber uses liquid paraffin and ethylene glycol as the main absorbents, wherein the liquid paraffin can dissolve organic substances such as hydrocarbons, benzene, ether, chloroform, carbon disulfide, and fatty oils; ethylene glycol has good compatibility with low-carbon alkanes and cycloalkanes; the oil-in-water emulsifier can fully and stably disperse the liquid paraffin in the aqueous solution; the surfactant, sodium citrate, and sodium carbonate help the absorbent transfer volatile organic compounds from the gas phase to the liquid phase and lock them in the liquid phase.

[0005] In combination with the detergent disclosed in patent CN117771890A, a multi-stage treatment device for suctioning organic waste gas from printing and dyeing is provided, which can extend the time for the waste gas to be washed in the detergent, and at the same time make the detergent flow continuously to prevent the detergent from having uneven concentration. Summary of the Invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a multi-stage treatment device for the extraction of printing and dyeing organic waste gas. The present invention performs secondary dust removal on the waste gas through a dust removal device I, and then washes it through a washing device.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1) After completing primary filtration and removing large particles of dust in dust removal device II, the exhaust gas enters the air collecting box in dust removal device I through air inlet pipe II, flows along the spiral baffle for dust reduction treatment, and passes through the filter plate for secondary filtration. At the same time, the exhaust fan I, electric motor I and conveying pipe cooperate to control the outlet pipe to rotate while inputting the exhaust gas into the detergent for gas washing. After the device has been running for a long time, motor I controls the filter plate to retract into the connecting groove on the spiral baffle. The electric push cylinder I controls the cleaning plate to clean the air collecting box, spiral baffle and filter plate, and drives the lifting cover to rise. After the cleaning plate is aligned with the bottom of the discharge port I, the cleaning mechanism is controlled to clean the dust on the cleaning plate to prevent excessive dust accumulation in the air collecting box and affect the device's exhaust gas treatment efficiency.

[0017] 2) Exhaust gas entering the detergent flows upward along the spiral blades in the scrubbing device, extending the distance the exhaust gas travels to the detergent surface and allowing it to be fully treated in the detergent. As the exhaust gas flows, some of it gathers at the connection between the spiral blades and the housing due to buoyancy, forming larger bubbles. At this point, the electric motor III cooperates with the rotating seat I to drive the rotating seat II to rotate, causing the connecting plate to drive one side of the connecting rod II to squeeze the spring up and down along the curved plate. This causes the guide strip on the other side of the connecting rod II to rotate and break up the bubbles, preventing them from gathering and preventing the exhaust gas inside the bubbles from being washed. At the same time, the gear meshes with the teeth on the curved plate, driving the blades to rotate, assisting the cyclone in breaking up the bubbles, further reducing their size and improving the efficiency of the detergent in treating the exhaust gas.

[0018] 3) At the same time, the water pump in the washing device extracts detergent from the bottom of the device through the spray pipe to rinse the washed exhaust gas. With the cooperation of the water pump and the spray pipe, the detergent in the upper layer of the device flows slowly and continuously to the lower layer of the device along the spiral blade, so that the detergent is continuously mixed, preventing the exhaust gas from only contacting the detergent at the same position, resulting in uneven detergent concentration and affecting the detergent's treatment effect on the exhaust gas. At the same time, the dust remaining in the exhaust gas enters the detergent and continuously settles under the influence of the spiral blade, preventing dust impurities from mixing with the detergent, affecting the purity of the detergent and causing the detergent to reduce the exhaust gas treatment effect.

[0019] 4) The washed exhaust gas passes through demister I and demister II and rises to the bottom of the turntable. At the same time, motor II cooperates with rotating seat III to control the guide groove to drive the turntable to rotate, so that the catalytic plate and lamp tube below the turntable cooperate to perform catalytic treatment. Then electric motor IV controls the fan blades to introduce the exhaust gas through the guide groove to the top of the turntable, and the exhaust gas is catalytically treated again through the catalytic plate and lamp tube above the turntable. At the same time, motor III cooperates with the screw to drive the lifting plate down through the rotating plate to concentrate the exhaust gas, thereby increasing the exhaust gas treatment rate of the catalytic plate and lamp tube.
