Description

[0002] The waste gas produced by cigarettes in the tobacco industry has the characteristics of large emission, complex composition and great harm, and is currently the focus of air pollutant control. Although the waste gas of cigarette factories can meet the emission standards, there is still a certain amount of odor diffusion due to incomplete treatment and collection problems. In addition, during the production, transfer and storage process, due to the volatilization of tobacco, some odor will volatilize and diffuse.

[0003] In recent years, cigarette factories have received many complaints about odors in the surrounding area, and the environmental protection pressure of enterprises is relatively high. There are many solutions currently adopted, one is a decentralized treatment solution, and the other is a centralized treatment solution. The decentralized treatment solution is to arrange absorption and treatment devices at the place where the odor is generated, that is, the absorption and treatment is carried out as soon as it is generated. The centralized treatment solution is to centrally transport the odor-generating gases from various places to the treatment equipment for absorption and treatment. Regardless of which method is used, adsorption treatment is required. At present, adsorption materials usually use adsorption consumables such as activated carbon, which need to be replaced regularly and have a high cost of use. Summary of the invention

The sliding pin 264 is fixedly mounted on the rotating shaft 222 and is perpendicular to the axial direction of the rotating shaft 222. An annular guide groove 265 is opened on the inner wall of the inner cylinder 221. The outer end of the sliding pin 264 slides in cooperation with the annular guide groove 265. The annular guide groove 265 is wavy and fluctuates back and forth in the up and down directions. The annular guide groove 265 cooperates with the sliding pin 264 to drive the inner cylinder 221 to reciprocate up and down.

[0029] The use process of the processing device provided in this embodiment is as follows:

[0030] First, the suction mechanism 100 absorbs air containing odorous gas molecules and discharges the gas into the interior of the cylinder 210 from the air inlet valve 211. The airflow rotates circumferentially along the cylinder 210 and is guided downward under the blocking and guidance of the annular plate 280, so that the airflow first fills the lower part of the inner cavity of the cylinder 210 and then flows upward. The flowing gas contacts the resin particles, and the resin particles absorb the odorous molecules therein. The treated gas is discharged through the exhaust valve.

[0031] The rotating shaft 222 is driven to rotate by the motor 260. The rotation of the rotating shaft 222 drives the spiral blade 223 thereon to rotate. The resin particles flow from the notch 224 of the inner cylinder 221 into the inner cavity of the inner cylinder 221. Under the action of the rotating spiral blade 223 and the inner wall of the inner cylinder 221, the resin particles are discharged upward, and the upper row of resin particles are discharged from the open end of the upper end of the inner cylinder 221 and fall in a diffused state. In the process of falling, the resin particles are separated from each other, so that the outer surfaces of the resin particles can contact with the air, thereby achieving full utilization of the outer surfaces of the resin particles.

[0032] During the falling process of the resin particles, they come into contact with the spiral guide plate 270, the rotating shaft 222 drives the driving gear 263 to rotate, the driving gear 263 drives the gear column 262 to rotate, the gear column 262 drives the inner gear ring 261 to rotate, the inner gear ring 261 drives the inner cylinder 221 to rotate, and the inner cylinder 221 drives the spiral guide plate 270 to rotate. Under the collision and centrifugal force of the spiral guide plates 270, part of the falling resin particles falls from the gaps between adjacent spiral guide plates 270, and part is rebounded and diffused around, and then falls again, which can prolong the time that the resin particles stay in the air, prolong the adsorption time of the resin particles, and improve the adsorption efficiency of the resin particles.

[0033] Part of the fallen resin particles will fall onto the extrusion plate 232. As the inner cylinder 221 rotates, the extrusion plate 231 rotates synchronously. When the extrusion plate 231 rotates to the top of the extrusion plate 232, the resin particles are constrained between the extrusion gap 230 of the two. As the extrusion gap 230 between the extrusion plate 231 and the extrusion plate 232 gradually becomes smaller, the resin particles can be squeezed to discharge the air in the pores of the resin particles, and the resin particles can be driven to roll on the extrusion plate 232, so that the pores of the resin particles in different directions can be squeezed and exhausted. In the process of rotation of the rotating shaft 222, the inner cylinder 221 can be driven to move up and down reciprocatingly through the action of the sliding pin 264 and the annular guide groove 265, so as to drive the extrusion plate 231 to move up and down reciprocatingly. The extrusion plate 231 continuously applies pressure to extrude the resin particles during the downward movement. During the upward movement of the extrusion plate 231, the resin particles recover under the action of their own elastic recovery, and the pores are inhaled, so that the resin particles have a breathing effect, and the inner surface of the pores of the resin particles is fully in contact with the air, so as to fully utilize the adsorption surface.

[0034] As the above-mentioned actions are continuously performed, the outer surface of the resin particles can be fully utilized, and the resin particles can also act like breathing, which effectively improves the utilization rate of the resin particles and the adsorption efficiency and effect.

[0035] During the water washing process, the air inlet valve 211 and the exhaust valve are closed, and the cleaning liquid is supplied to the cylinder 210 through the liquid inlet valve 251. It should be noted that the sealing plate 266 is used to achieve the sealing isolation of the upper and lower reciprocating drive mechanism and transmission mechanism of the lower part of the inner cylinder 221 and the upper space of the inner cylinder 221. The cleaning liquid is rushed into the cylinder 210, and the movement of the resin particles is the same as described above, so that the resin particles can flow up and down in the cleaning liquid, and the resin particles can be squeezed to cooperate with the self-restoration effect of the resin particles, so that the cleaning liquid can fully enter and exit the pores of the resin particles, and the odor molecules adsorbed on the outer surface and pores of the resin particles can be washed more thoroughly. After washing, the cleaning liquid is discharged from the liquid outlet valve 252, and the above-mentioned actions are repeated to squeeze the resin particles, so that the aqueous solution absorbed in the pores of the resin particles can be squeezed out, and under the cooperation of the action of the inner cylinder 221 driving the spiral guide plate 270 and the squeezing plate 231 to rotate continuously, the resin particles are driven to rotate, and continuously collide with the inner wall of the cylinder 210 and the outer wall of the inner cylinder 221, so as to realize the dehydration action, and the dehydration effect is good.

[0036] The device for suppressing the unorganized emission of tobacco odor gas proposed in this embodiment uses porous elastic adsorption resin to adsorb odor gas molecules. The resin has high utilization efficiency and good resin adsorption effect. It can be washed and reused without replacing materials and has low use cost.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
