(3) repeat step (2), to spices collector cycling on each exhaust branch pipe, and the absorbent in the fragrance absorption pipe taken off is poured out, carry out supercritical CO according to a conventional method
2extraction, obtained this spices grease of tobacco, isolated absorbent recycles;
(4), after described deduster runs 1-5 days, take out the dust in described dust collection container, carry out supercritical CO according to a conventional method
2extraction, obtained this spices grease of tobacco, isolated dust is discarded;
(5) repeat step (2), (3), realize continuous seepage.
In tobacco leaf processing waste gas of the present invention, the extraction element of this spices of tobacco, adopts supercritical CO
2the method of extraction carries out the extraction of this spices of tobacco in tobacco leaf processing waste gas and dust, and thus obtained this spices purity of tobacco can reach more than 99.5%; By the mode that multiple branch circuit absorbs, achieve the continuous seepage of tobacco leaf processing and this fragrant fragrance absorption of tobacco, extraction, and without the leakage of toxic and harmful; The present invention not only carries out sufficient separation and extraction to this fragrant fragrance component of tobacco in tobacco leaf processing waste gas, and this spices of the tobacco in waste gas contained by dust is extracted completely, thus this spices of tobacco making tobacco leaf process in waste gas all reclaims, obtain good economic benefit, avoid the waste of this spices of tobacco in waste gas and the environment brought by toxic emission and atmosphere pollution.It is simple that extraction element of the present invention has structure, easy to operate, the advantages such as dependable performance.
Accompanying drawing explanation
Fig. 1 is the structural representation that in the present invention, tobacco leaf processing waste gas extracts this fragrant fragrance device of tobacco.
Detailed description of the invention
As shown in Figure 1, tobacco leaf processing waste gas of the present invention extracts this fragrant fragrance device of tobacco, on tobacco leaf processing exhausting waste gas pipeline 23, be connected with booster fan 1 and deduster in turn, the gas outlet of deduster is communicated with at least 2 exhaust branch pipes 11, each exhaust branch pipe 11 is arranged 1 spices collector 12, the gas outlet of multiple spices collector 12 can be communicated with exhaust main 18, is collected by the waste gas after extraction tobacco leaf spices and enters air.Described deduster can adopt sack cleaner 2, obtains the Purge gas not having dust, and the bottom of sack cleaner 2 arranges dust collection container 7, for collecting the dust in tobacco leaf processing waste gas, then extracts wherein contained this spices of tobacco.Described sack cleaner 2 has an airtight housing 21, dust-removal cloth-bag 22 is provided with in housing 21, tobacco leaf processing waste gas enters dust-removal cloth-bag 22 by the air inlet at housing 21 top, Purge gas after filtering enters the cavity between dust-removal cloth-bag 22 and housing 21, and discharged by the gas outlet of side, housing 21 bottom, separating obtained dust is discharged by the dust fall mouth bottom housing 21.Described sack cleaner 2 is provided with impulse ash blower, described impulse ash blower comprises high-pressure pump 10, high pressure draught nozzle 3 and controller 4, described high pressure draught nozzle 3 is positioned at the top of sack cleaner 2, and put in dust-removal cloth-bag 22, under the control of controller 4 by setting jet time interval and frequency to dust-removal cloth-bag 22 inwall inject high pressure air-flow, the dust be deposited with on dust-removal cloth-bag 22 wall is constantly come off, greatly can improve efficiency of dust collection.The air inlet of described high-pressure pump 10 can be communicated with the gas outlet of sack cleaner 2, directly utilizes the dust on tobacco leaf processing waste gas blowback dust-removal cloth-bag 22 wall after purification, avoids the increase of subsequent absorption process exhausted air quantity.Can the rotary blanking mechanism of airtight connection one bottom sack cleaner 2, this rotary blanking mechanism has a housing 6, in housing 6, several material-falling hoppers 9 are set by main shaft 8, described main shaft 8 realizes intermittence by stepper motor (not shown) and controller 5 and determines angle rotation splicing, and the Leakage Gas in dust-removal cloth-bag 22 can be prevented, the material-falling hopper 9 forwarding below to dust is toppled over as described in dust collection container 7.Described spices collector 12 comprises housing 13 and end cap 14, and the air inlet of described housing 13 is communicated with the gas outlet of sack cleaner 2 by exhaust branch pipe 11, and exhaust outlet is communicated with described exhaust main 18.Several fragrance absorption pipes 16 and absorption tube holder 15 are set in housing 13, absorption tube holder 15 is arranged several through holes, for plug-in mounting fragrance absorption pipe 16, described fragrance absorption pipe 16 outer circumferential sides can arrange annular boss, locate for plug-in mounting, and preventing the leakage of gas, fragrance absorption pipe 16 two ends arrange expanded metals, and inner chamber has granular solids absorbent 17.Each exhaust branch pipe 11 is provided with control valve 20, controls the break-make of respectively this exhaust branch pipe 11 respectively.
The method that the present invention uses this fragrant fragrance device of above-mentioned tobacco leaf processing waste gas extraction tobacco to carry out the extraction of tobacco leaf spices is: after startup tobacco leaf processing exhaust emission suction system, namely described deduster and impulse ash blower thereof and rotary blanking mechanism is started, open the control valve 20 of each exhaust branch pipe simultaneously, Purge gas now after dedusting is simultaneously by each spices collector 12, wherein contained fragrance component is adsorbed by absorbent 17, the waste gas absorbed after spices is discharged in air by the gas outlet of spices collector 12 through described exhaust main 18, and thereby eliminate environmental pollution.According to test determination, the absorbent 17 run after 12-24 hour in fragrance absorption pipe reaches and substantially adsorbs saturation state, at this moment the control valve 20 of an exhaust branch pipe 11 is first closed, open the end cap 14 of spices collector 12 on this exhaust branch pipe 11, take out the fragrance absorption pipe 16 in it, installed by end cap 14 after the fragrance absorption pipe 16 changing the outfit new after fixing, the control valve 20 opening this exhaust branch pipe 11 continues to run; On this exhaust branch pipe 11 of replacing in spices collector 12 while fragrance absorption pipe 16, the spices collector 12 on other exhaust branch pipe 11 normally runs, and thus without the need to stopping the operation of preorder flow process, also there will not be the leakage pollution containing tobacco leaf spices waste gas.Absorbent 17 in the fragrance absorption pipe 16 taken off to spices collector 12 cycling on each exhaust branch pipe 11, and is poured out by circulation like this, namely completes gathering of tobacco leaf spices.Then absorbent 17 method routinely pouring out collection is carried out supercritical CO
2extraction, i.e. obtained this spices grease of highly purified tobacco, isolated absorbent can be recycled.While carrying out spices collector 12 operation, depending on the size of described dust collection container capacity and the running rhythm of extraction procedure, after described deduster runs 1-5 days, the dust in described dust collection container 7 can be taken out, carry out supercritical CO according to a conventional method
2extraction, obtained this spices grease of tobacco, isolated dust is discarded, and realizes the continuous seepage of tobacco leaf processing and the extraction of this spices of tobacco thus.
