Embodiment 1

[0023] Such as figure 1 As shown, a device for extracting tobacco flavor and fragrance from tobacco leaf processing waste gas of the present invention includes a fragrance collector whose base 1 communicates with the waste gas exhaust pipe. The butt joint structure of the seam and the sealing gasket 14. The upper part of the lower section 2 of the housing is provided with a fragrance absorption screen 5 through the flange or the boss 13, and the absorbent 4 is spread in the fragrance absorption screen 5. Tube 9. The absorbent 4 is composed of 30 parts of activated carbon, 30 parts of silica gel and 30 parts of zeolite in parts by weight. The particle diameter of the absorbent 4 is 3 mm, and has a larger surface area for the adsorption of spices in the exhaust gas. The thickness of the absorbent is 10 cm, which can pass the exhaust gas relatively smoothly, and make the exhaust gas and the absorbent There is ample opportunity for contact absorption. One deck of screen cloth ...

Embodiment 2

[0027] This solution is basically the same as that of Example 1, except that the absorbent 4 is composed of 20 parts by weight of activated carbon, 40 parts of silica gel and 40 parts of zeolite. The particle diameter of the absorbent 4 is 1.5 mm, and has a larger surface area for the adsorption of spices in the exhaust gas. The paving thickness of the absorbent 4 is preferably 20 cm, and each layer of paddles 11 is radially arranged with 3 pieces; In the process of extracting tobacco flavors and fragrances, the rotation speed of the stirring paddle was adjusted to 20 rpm; the absorption time was set to 36 hours. According to laboratory analysis, the recovery rate of tobacco flavors and fragrances in the exhaust gas was 91.6%.

Embodiment 3

[0029] This solution is basically the same as that of Example 1, except that the absorbent 4 is composed of 10 parts by weight of activated carbon, 50 parts of silica gel and 50 parts of zeolite. The particle size of the absorbent 4 is 1 mm, and has a larger surface area for the adsorption of tobacco flavors and fragrances in the exhaust gas. The thickness of the absorbent 4 is 30 cm, and each layer of blades 11 is radially arranged with 4 pieces; In the process of extracting tobacco flavors and fragrances, the rotation speed of the stirring paddle was adjusted to 10 rpm; the absorption time was set to 48 hours, and the recovery rate of tobacco flavors and fragrances in the exhaust gas was 95.3%.

Abstract

The invention discloses an extraction device and an extraction method for tobacco bois flavors in tobacco processing waste gas. The extraction device comprises a flavor collector communicated with a waste gas exhaust pipeline; the flavor collector is provided with a housing formed by two sections in an abutting-jointing manner; a flavor absorption sieve is arranged inside the lower section of the housing; an absorption agent is paved in the flavor absorption sieve; the lower section and the upper section of the housing are respectively communicated with an intake pipe and an exhaust pipe. As the device is used for extracting the tobacco bois flavors, the complete separation of the tobacco bois flavors can be guaranteed, and a relative high extraction recycling rate can be reached.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing, and in particular relates to an extraction device and method for extracting tobacco essential flavors and spices from waste gas from tobacco leaf processing. Background technique [0002] A large amount of waste gas is produced in the process of cigarette shredding and smoking re-examination. The waste gas often has a strong pungent smell unique to tobacco. It is mainly volatile substances released from tobacco leaves or shredded tobacco. These volatile substances are an important aroma of cigarettes. Ingredients play an important role in maintaining the original ecological quality of cigarettes. Therefore, these exhaust gases are directly discharged into the atmosphere, which not only brings relatively serious environmental pollution, but also causes a waste of useful components in tobacco leaf resources. [0003] In recent years, the recovery of useful components in tobacco-ma...
