Abstract

The invention relates to a method for removing tar in a manufacturing process of pyroligneous. The main component of the pyroligneous liquor is generated in the carbonization process of the plants; is plant organic composite acid, water and wood tar. Most of the refined wood vinegar liquid published at present uses activated carbon to adsorb, stand and filter to remove residues. The traditional method is not beneficial to industrial production due to long operation time. The most important point is that the smoke smell in the wood vinegar cannot be effectively removed by any method for refining the wood vinegar, and the deep processing and popularization and application of the wood vinegar are directly influenced. The method has the beneficial effects that the tar component is removed when the pyroligneous liquor is generated, so that the subsequent refining of the pyroligneous liquor becomes simple and convenient, time-saving, low in energy consumption and cost, low in loss of the plant organic composite acid, low in tar content and free of smoke smell.

Description

The method of a kind of wood vinegar tar removing in making processes

Technical field:

The present invention relates to vegetable hot cracking field, is a kind of method of tar of removing in manufacturing processed about wood vinegar.

Background technology:

Plant in anaerobic charing thermal cracking processes, a kind of volatilizable reddish-brown water soluble mixt of generation, its main component; The materials such as water, organic acid, alcohols, ketone and phenols nearly more than 300 are planted, and this material can be used as chemical industry and refines and the synthetic basic raw material of organic acid.

Wood vinegar after refining can be used as foodstuff additive, preservation agent, and medical aspect can be used as antiseptic-germicide, wormer, and the makeup aspect can be used for beauty treatment, skin makeup, in addition also effectively Acne treatment and beriberi of wooden vinegar.

In the relevant acetum pyrolignosum rectificatum liquid of the major part of delivering at present, be all that the use charcoal absorption is standing, mistake elimination residue; Use traditional way operating time length to be unfavorable for that suitability for industrialized production, the most important are to use any method all can not effectively remove the sootiness taste in wood vinegar for the refining of wood vinegar, directly have influence on the deep processing of wood vinegar, and promote the use of.

Summary of the invention:

The effect that the present invention is useful is to remove tar ingredients when wood vinegar generates, make follow-up wood vinegar refiningly become easy, save time, energy consumption is low, cost is low, plant organic composite acid loss is low, tar content is low, the wooden vinegar refined liquid of smokeless smoke flavour.

The accompanying drawing explanation:

The method equipment block diagram that figure is a kind of wood vinegar of the present invention tar removing in making processes.

Embodiment:

The present invention is achieved by following scheme.

1. the high temperature pyrolysis gas by adjustable charing converter 1 output of anaerobic temperature speed outputs to equipment 2 tar separators through sealing member 7, because impurity, tar molecular weight are greater than in organic composite acid molecular weight by the effect of physics, therefore drop to the bottom of cone separator, collected by impurity tar receiving tank.The slag gas separating device is used the stainless steel tapered shaped can, and connecting device 3 impurity tar receiving tanks, with straight-through the connection using stainless steel sluice valve.Equipment 3 arranges residual cake valve for the encloses container bottom.

2. through equipment 2 gas tar separator after separating for the first time, with the vegetable hot cracking of part tar and fine small impurities through equipment 4 tar setting tanks through physical actions such as coolings, most of fine impurity and tar molecule are collected again.

3. the tar impurity of collecting through the secondary holding tank is collected rate and reaches more than 90%, has greatly lowered the tar in the wood vinegar, foreign matter content, has clarified the color and luster of wood vinegar, for next step wood vinegar is refining, lays a good foundation.

The composition of the tangy flavour in wood vinegar is comparatively complicated, but main component is carbolineum, washing oil in wood tar oil, these two kinds of materials are water-soluble, and in wood vinegar organic acid content generally in 10% left and right, the content of water reaches 90% more than, so wood vinegar is made in the early stage and the exquisite course of processing of later stage in must effectively reduce the content of above-mentioned two kinds of materials, could effectively remove the sootiness taste.

Claims

1. adopt anaerobic charing mode to the plant pyrolysis, become more readily available through this case serial equipment that tar content is low, impurity is low, tangy flavour is low wood vinegar.

2. technique according to claim 1 is characterized in that the function that equipment is removed tar, but does not affect the Quality and yield of wooden vinegar.

3. according to claim 1. anaerobic charing mode, the plant pyrolysis is removed to tar through serial equipment;

1. the adjustable charing converter of anaerobic temperature speed connects 2 tar gas separators through sealing member 7, carries out tar gas for the first time and separates.

2. be collected and enter 3 tar impurity receiving tanks through tar gas separator 2 part tar impurity.

3. tar gas separator 2 the other ends connect tar setting tank 4 in the tar setting tank, carry out tar foreign gas for the second time and separate.

4. after secondary tar impurity is separated.The vegetable hot cracked gas is collected into wooden vinegar finished pot 6 through condenser 5.

4. according to claim 1 anaerobic charing mode, the plant pyrolysis is passed through to above-mentioned technical process, make the wooden vinegar finished product of collecting, the tar removal of impurity can reach more than 90%, and color and luster can reach glassy yellow, has created good basic condition for follow-up wood vinegar is refining.
