Description

A kind of utilization wood material refines the refinement system and its technique of pyrolkigneous liquid

Technical field

The invention belongs to Field of Fine Chemicals, specially a kind of utilization wood material refine pyrolkigneous liquid refinement system and Its technique.

Background technology

Pyrolkigneous liquid is the natural extract that wood materials are pyrolyzed that fractionation flue gas is produced in still-process, is that a kind of component is answered Miscellaneous, vdiverse in function and metastable system material.Pyrolkigneous liquid is generally filbert to dark brown translucent liquid, there is unique cigarette Stacte gas, sour, pH value 1.5~3.7, proportion 1.0025；It contains 200 gas chromatographies, including phenols, acids, alcohols, ketone Class etc., complicated component, vdiverse in function, the natural balance of numerous micro substance factors holdings.

The bioactive functions of pyrolkigneous liquid are various, start to be widely used in agricultural, forestry, animal husbandry, food processing industry, doctor Medicine health industry and light industry industry；And there are many magical effects in actual applications.Agriculturally, pyrolkigneous liquid is fine Green fertilizer and agricultural chemicals, the mixture of the gas chromatography contained by it have promote plant growth, it is soil disinfection, sterilization, anti- A variety of effects such as worm anti-corrosion, weeding and deodorization, are alternatively arranged as micro- fertilizer and use, and improve crop yield and quality, in answering agriculturally With more and more extensive.Medical aspect, pyrolkigneous liquid can be as medicine and the adding ingredient of cosmetics, to idiosyncrasy disease property after refining Dermatitis, eczema and wound wound are effective in cure.In recent years as consumer is advocated natural plant extract, pyrolkigneous liquid is used as green One of natural plant-based bacteriostat, international market, which increasingly increases the demand of pyrolkigneous liquid, to be sharply increased.

At present, the producer of domestic special production pyrolkigneous liquid is considerably less.Although it is good that pyrolkigneous liquid can produce industry as charcoal Byproduct, but general charcoal manufacturer in charcoal production it is many by fume emission into air, pyrolkigneous liquid is not obtained Fractionation is reclaimed；Even if some charcoal manufacturers are reclaimed, also it is not collected effectively, refined.And on the other hand, wood The flue gas produced in charcoal sintering procedure is discharged into air extensively, the severe contamination such as CO, NO that wherein incomplete combustion is produced Environment.

Apricot shell is obtained by the mature seed broken shell of rose department cherry genus apricot or ansu apricot kind.Apricot chitin is close, tough and tensile, can through pyrolysis Obtain pyrolkigneous liquid.Publication No. 101074382A Chinese invention patent (Application No. 200710011840.8) disclose it is a kind of from The process of pyrolkigneous liquid is extracted in apricot shell, apricot shell is added in retort, completely cuts off air in the case where temperature is 450~550 DEG C Pyrolysis 4~6 hours, condenses the gas-phase product drawn from retort, takes coercibility part to obtain crude pyroligneous acid；Crude pyroligneous acid is quiet Put more than 30 days, isolate 3 layers, by middle level in 90~120 DEG C of rectifying 4~6 hours, condensation is acetum pyrolignosum rectificatum liquid product.

Although the disclosure of above-mentioned patent discloses the technical scheme that acetum pyrolignosum rectificatum liquid is provided by the use of apricot shell as original pyrolysis, But its whole technique is time-consuming, laborious, especially pyrolkigneous liquid refined part first has to stand up to 30 days, after layering still Refined using traditional pyrolkigneous liquid heating, its producing efficiency is greatly slowed down, delayed；And the sizable advantage of pyrolkigneous liquid it One is the overall balance of a variety of organic principles, and it retains middle level rectifying after the standing, and what is included in the upper strata that discards, lower floor has Machine composition is wasted unfortunately.In addition, energy charge is also than larger in pyrolkigneous liquid production process.
