Detailed description of the invention
For making content of the present invention become apparent, below in conjunction with specific embodiment, describe the present invention.
As shown in the figure, a kind of steam for nicotine extraction occurs and sour absorption plant, be provided with the jacket type enamel still 2 that an inside is loaded with sour absorbing liquid 1, the top of described jacket type enamel still 2 is sealed by upper end cover 3, upper end cover 3 is provided with centre bore and two side openings, the bottom connected drainage pipe 4 of jacket type enamel still 2, and discharging tube 4 is provided with glass valve 5, the centre bore of upper end cover 3 is connected with cylindricality enamel cylinder 6, and junction is provided with porous barrier 7; Two side opening places of upper end cover 3 are connected to temperature control probe sleeve 8 and containing nicotine steam ingress pipe 9, insert in sour absorbing liquid 1 containing nicotine steam ingress pipe 9 through side opening;
Porcelain filler 10 is filled with in described cylindricality enamel cylinder 6, the top of cylindricality enamel cylinder 6 is sealed by cover, cover is provided with sour absorbing liquid charge pipe 11 and steam delivery line 12, acid absorbing liquid charge pipe 11 one end connects is equipped with the head tank 13 that acid absorbs stoste 20, the other end stretches in the porcelain filler 10 of cylindricality enamel cylinder 6, described steam delivery line 12 one end is connected with the preformed hole being positioned at cylindricality enamel cylinder upper flanges lid, and steam delivery line 12 other end is connected with steam distillation tank.
In order to make the present invention, there is better result of use, the outer surface of described jacket type enamel still 2 and cylindricality enamel cylinder 6 is equipped with heat-insulation layer 23, the sidewall of jacket type enamel still 2 is also respectively equipped with illumination port and viewport, and illumination port and viewport are oppositely arranged the both sides of jacket type enamel still 2.Described discharging tube 4 is equipped with sealing device 19 with between jacket type the enamel still 2 and port that is connected with head tank 13 and sour absorbing liquid charge pipe 11 of sour absorbing liquid flow control valve 22.
In technical scheme of the present invention, on described steam delivery line 12, along stream of water vapor to being provided with pressure vacuum meter 14, temp probe 15, stream of water vapor control valve 16 successively, bleed blower fan 17 and sample cock 18, the described nicotine steam ingress pipe 9 that contains is provided with containing nicotine stream of water vapor control valve 21, and sour absorbing liquid charge pipe 11 is provided with sour absorbing liquid flow control valve 22.
Using method of the present invention:
The acid of step one, preparation debita spissitudo absorbs stoste 20, joins in head tank 13.
Step 2, open water vapor flow rate control valve 16 and sample cock 18, close glass valve 5 and containing on nicotine steam ingress pipe 9 containing nicotine stream of water vapor control valve 21, the illuminating lamp of opening clamp shell type enamel still 2, open the sour absorbing liquid flow control valve 22 on sour absorbing liquid charge pipe 11, the acid solution of about 1/3rd is put in jacket type enamel still 2, closes sour absorbing liquid flow control valve 22.
Step 3, the control temperature arranging the heating jacket of jacket type enamel still 2 are 110 DEG C, start heating, about 105 DEG C are boiled when the temperature in the kettle of jacket type enamel still 2 reaches micro-, namely sample cock 18 is emerged steam, unlatching is bled blower fan 17 and containing nicotine stream of water vapor control valve 21, close sample cock 18, regulate sour absorbing liquid flow control valve 22 to drip acid with the speed of 1 about per second and absorb stoste 20.
Step 4, detect steam by steam sample cock 18, if pH >=8 of steam and the pH < 3 of sour absorbing liquid 1, then should strengthen the rate of addition of sour absorbing liquid or turn down containing nicotine stream of water vapor control valve 21.
Step 5, absorb the increase of nicotine amount along with sour absorbing liquid 1, it absorbs the decline of the speed of nicotine, vapour pressure reduces, therefore the rate of addition that acid absorbs stoste 20 should be strengthened, and note observing pressure vacuum meter 14, heighten the control temperature of heating jacket or turn stream of water vapor control valve 16 down, maintaining system pressure at 1 atm higher;
Step 6, when sour absorbing liquid 20 quantity not sufficient in head tank, release appropriate amount of acid acid absorbing liquid 1 in jacket type enamel still 2 by glass valve 5 in time and transfer in head tank 13;
