Detailed implementation manners

[0027] As Figures 1 to 5 shown, a nicotine tail gas treatment device disclosed by the present invention includes a tail gas treatment box 1. The tail gas treatment box 1 is square. Inside the tail gas treatment box 1, a positive pressure blowing layer 2, an activated carbon layer 3, an adsorption and drying layer 4, a lower side support plate 5 and a washing layer 6 are sequentially arranged from top to bottom. In some other embodiments, the cross-section of the tail gas treatment box 1 is circular. Correspondingly, the positive pressure blowing layer 2, the activated carbon layer 3, the adsorption and drying layer 4, the lower side support plate 5 and the washing layer 6 are all circular. Each layer is hermetically matched to prevent gas leakage. The washing layer 6 described here refers to a layer filled with washing liquid, and a suitable layer height can be selected according to needs.

[0028] Specifically, the washing layer 6 disclosed by the present invention is filled with washing liquid. The washing liquid adopts a combination of activated carbon solution, chemical absorption liquid or other chemical liquids, and can effectively absorb harmful gases such as nicotine, tar, carbon monoxide and carbon dioxide in the nicotine tail gas. The absorbed liquid can be updated in time through the water replenishing hole 9 and the drain hole 7, thus avoiding the problem of reduced filtration effect caused by impurity saturation.

[0029] In order to facilitate gas absorption and liquid treatment, the device of the present invention is provided with a drain hole 7 and an air inlet hole 8 communicating with the washing layer 6 at the lower part of the tail gas treatment box 1. The gas is directly introduced into the washing liquid, and absorption can be better carried out. A water replenishing hole 9 is arranged on the upper side of the washing layer 6 to realize water replenishing while draining water, and the liquid can be updated faster. The drain hole 7 is connected to the soil planting area through a drain pipe 10. The planted plants are selected as plants that can absorb nicotine and other gases, so as to achieve the effect of green filtration.

[0030] The device of the present invention provides the power for drainage through a water pump. The water replenishing hole 9 is connected to a water tank, and the water tank is used for a continuous water source; of course, the water tank can also be replaced by a water supply device. An air guiding component 12 is installed on the lower side support plate 5, and the air guiding component 12 is used to discharge the gas cleaned by the positive pressure blowing layer 2 through the activated carbon layer 3 and the adsorption and drying layer 4 into the washing liquid for absorption and storage. Among them, during tail gas treatment, the nicotine tail gas first enters the washing layer 6 through the air inlet hole 8 for primary filtration, and the excess gas is discharged after being filtered by the adsorption and drying layer 4 and the activated carbon layer 3 in sequence.

[0031] In some other embodiments, the positive pressure blowing layer 2 directly uses a blower, which can be installed on the upper side of the activated carbon layer 3 and can blow downward to clean the activated carbon layer 3 and the adsorption and drying layer 4.

[0032] In the embodiment of the present invention, the adsorption and drying layer 4 can be used for drying to prevent the contaminated washing liquid from entering the activated carbon layer 3, and can also assist in filtration. The lower side support plate 5 is mainly used to support the above-mentioned layers, and a plurality of through holes are provided on the lower side support plate 5 to prevent interference with the discharge of gas.

[0033] Usage process: When it is necessary to clean the activated carbon layer 3 and the adsorption and drying layer 4, start the positive pressure blowing layer 2 to apply positive pressure wind force to the activated carbon layer 3 and the adsorption and drying layer 4, and discharge the impurities on the activated carbon layer 3 and the adsorption and drying layer 4 into the washing layer 6 through the air guiding component 12, and update the washing liquid in the washing layer 6 through the water replenishing hole 9. The contaminated washing liquid is then discharged from the box body along the drainage hole 7, so as to deeply clean the activated carbon layer 3 and the adsorption and drying layer 4, which can achieve the effect of repeated use. Using the device of the present invention has lower cost and good tail gas adsorption effect.

[0034] In some other embodiments, the air guiding component 12 can directly use an air guiding pipe, and the lower end of the air guiding pipe is inserted into the washing liquid to be used to introduce the gas on the upper side into the inner side of the washing liquid along the pipe, which is more conducive to the absorption of the contaminated gas.

[0035] In this embodiment, the air guiding component 12 further includes 3 groups of exhaust blades 13 evenly distributed at the lower end of the air guiding pipe. The air guiding pipe is installed on the lower side support plate 5, and the upper end of the air guiding pipe faces the side where the adsorption and drying layer 4 is located to receive the gas above. A plurality of main channels 14 communicating with the air guiding pipe are provided inside the exhaust blades 13, and air outlet holes communicating with the main channels 14 are provided on the side edges of the exhaust blades 13. By discharging the gas from the side of the exhaust blades 13, the area for the gas to be distributed and discharged can be larger, which is more conducive to the full contact between the gas and the washing liquid, and thus more conducive to the absorption of harmful gases.

[0036] In this embodiment, the air outlet is connected to the main channel 14 through the branch channel 15. A plug 16 for blocking the air outlet is installed at the air outlet, and a first elastic stretching device 17 connected to the plug 16 is installed in the branch channel 15. The first elastic stretching device 17 uses a spring to provide an inward elastic pre-tension force to the plug 16. Under normal circumstances, the plug 16 blocks the air outlet, which can prevent the washing liquid from flowing back into the exhaust blade 13. When cleaning gas is required, the positive pressure gas provided by the positive pressure blowing layer 2 enters the main channel 14 and the branch channel 15 through the air duct. The air pressure drives the plug 16 to open, enabling normal exhaust.

[0037] In some other embodiments, a filter screen is also installed in the air duct to filter some solid impurities and prevent blockage of the branch channel 15. It is only necessary to clean the impurities regularly or replace the filter screen.

[0038] In this embodiment, the positive pressure blowing layer 2 intermittently provides downward wind force, and the wind force gradually increases. The air duct includes an inner tube 18 and an outer tube 19. The inner diameter of the outer tube 19 is adapted to the outer diameter of the inner tube 18. The upper end of the inner tube 18 is connected to the lower support plate 5. The upper end of the outer tube 19 is slidably sleeved outside the inner tube 18. A through hole 20 communicating with the main channel 14 is opened in the lower part of the outer tube 19. A baffle 21 is provided at the lower end of the outer tube 19. A piston ball 22 is slidably and sealingly installed inside the outer tube 19. The piston ball 22 is connected to the inner tube 18 through a second elastic stretching device 23. A third elastic stretching device 24 is connected between the outer tube 19 and the lower support plate 5. The blowing mode of the positive pressure blowing layer 2 is intermittent. When blowing downward, the positive pressure wind can drive the piston ball 22 to move downward until the piston ball 22 contacts the baffle 21 at the lower end of the outer tube 19. The piston ball 22 vacates the position of the through hole 20. At this time, the positive pressure can drive the outer tube 19 to move downward, and the outer tube 19 drives the exhaust blade 13 to move downward together. Since the wind force continuously increases, the outer tube 19 can be continuously moved downward. At this time, the gas continuously discharges from the exhaust hole, so the gas discharge in the entire height direction is realized, and the gas absorption can be made more sufficient.

[0039] After the positive pressure blowing layer 2 stops blowing downward, the piston ball 22 returns to its original position under the action of the second elastic stretching device 23, and the outer tube 19 returns to its original position under the action of the third elastic stretching device 24. The outer tube 19 moves upward to the initial position.

[0040] In this embodiment, the plane of the exhaust vane 13 intersects with the axis of the air duct at a certain angle. When the air outlet hole discharges air, it can disturb the water flow and drive the air duct to rotate. By rotating, the position of the exhaust hole can be changed in real time, which can also make the gas absorption more sufficient to a certain extent. A sleeve 25 is rotatably and cooperatively installed on the outer side of the outer tube 19. The outer tube 19 is connected to the third elastic stretching device 24 through the sleeve 25. The sleeve 25 is slidably and sealingly cooperated with the inner tube 18. The rotational connection between the sleeve 25 and the outer tube 19 can be realized.

[0041] In some other embodiments, the air duct can also be connected to a rotational drive device. In the embodiment of the present invention, air pressure is used for driving the rotation. By the distribution manner of the exhaust vane 13 itself, the structure can be simplified.

[0042] In this embodiment, the air guiding assembly 12 further includes a push-pull baffle layer 26 arranged on the upper side of the lower support plate 5. The push-pull baffle layer 26 is connected to the drawer of the tail gas treatment box 1 in a drawer type. A tapered hole 27 with a larger upper part and a smaller lower part is formed in the push-pull baffle layer 26. The tapered holes 27 correspond to the air ducts one by one. By providing the tapered holes 27, it can be used to guide the gas and reduce the occurrence of air leakage and other situations.

[0043] In this embodiment, an upper support plate 28 is installed on the upper side of the push-pull baffle layer 26. A guiding space for guiding the push-pull baffle layer 26 during pushing and pulling is formed between the upper support plate 28 and the lower support plate 5, which can facilitate the pushing and pulling of the push-pull baffle layer 26.

[0044] In this embodiment, the positive pressure blowing layer 2 includes a mounting frame 29, a rotating shaft 30 rotatably installed at the center of the mounting frame 29, fan blades 31 fixedly installed on the rotating shaft 30, and a rotational drive device connected to the rotating shaft 30. The rotational drive device can drive the fan blades 31 to rotate. After the fan blades 31 rotate in the forward or reverse direction, the blowing direction can be adjusted. When blowing air upward, it is more helpful for the gas to be discharged.

[0045] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
