Description

A kind of biomass carbonated destructive distillation purification recovery device and method
Technical field
The present invention relates to biomass carbonization techniques, and in particular to a kind of biomass carbonated destructive distillation purification recovery device and side Method, can be applied to log, wooden machine-made stick and with the machine-made stick that agricultural wastes are done extensively such as rice husk, corncob and beans bar Destructive distillation is to produce charcoal.
Background technology
Charcoal is that timber or wood material pass through imperfect combustion, or are pyrolyzed in the absence of air conditions, is remained Dark brown or black porosu solid fuel.Pyrolysis charring raw material is mainly with two kinds of principal modes of shaping mechanism bar and log.
Using sawdust as raw material, sawdust after machine high temperature, high-pressure molding, mechanism made of charing is re-fed into retort Charcoal need not add any additive in entire production process, it has, and burning time is long, calorific value is high, does not smolder, not detonation, environmental protection The features such as.The main hexagon center of machine-made carbon is free and there is two kinds of hole shape at square center.
Merely using trees as raw material, fired using kiln/stove(Even accumulation is made charcoal)Made of conventional charcoal, except using agricultural Waste fruit tree, fruit branch carry out the project of deep processing and comprehensive utilization, are a kind of industry for damaging resource, production process production mostly Raw flue dust, gas and raffinate arbitrarily discharges, serious to air, soil pollution, is forbidden by country now.
Charcoal main component is carbon, and ash content is very low, and calorific value about 27.21 ~ 33.49MJ/kg, in addition there are hydrogen, oxygen, nitrogen And a small amount of other elements, content depend primarily on the final temperature of charing.Now, it in addition to still making life fuel, also serves as Metal smelt, food and light industry fuel, the reducing agent of electric furnace smelting, when metal is refined as coverture protect metal not by Oxidation.Often make the raw material of carbon disulfide and activated carbon etc. on chemical industry.Fuel as Biscuits Factory, smeltery etc., is also used In the filtering of water, the decoloration of liquid and prepare black powder etc..Also in grinding, drawing, makeup, medicine, gunpowder, carburizing, powder The application of aspects such as alloy.
There are two types of preparation methods:
(1)Kiln process builds kiln with soil, completely fills timber, from wicket or vent point combustion, so that timber is carbonized in kiln, volatile matter It escapes and remaining charcoal;
(2)Cracking process, the i.e. dry distillation of wood.According to flameout method difference, two kinds of black wood charcoal and hard charcoal can be produced.
Usually it is called in kiln/stove method of stopping working in the method that bored kiln/stove stops working, that is, completely cuts off air and stop working, obtained charcoal claims For " black wood charcoal ".It when timber carbonizes in kiln/stove to be finished, claws or pours out out of kiln/stove while hot, then wet sand soil is used to stop working Flame-out method outside method, referred to as kiln/stove.During flame-out, charcoal is contacted with air and is calcined, and the outside of charcoal is aoxidized, The white ash of generation is attached on charcoal, referred to as " hard charcoal ".

Step 2 raw material is in externally heated retort oven(4)Complete dry, destructive distillation in inside;The destructive distillation product that destructive distillation generates is carbonized, from outer Heating type retort furnace(4)Top, which is sucked out, enters single stove vertical tube cooler(5), enter gas gathering manifold through collecting after primary wash(6);
Step 3 is from gas gathering manifold(6)Derived HYBRID RETORTING gas enters cyclone dust collectors(7), double purification recycling is carried out, and Afterwards, destructive distillation product goes successively to vertical pipe type inter cooler(8), exchange heat with recirculated cooling water, after heat exchange, net carbonization gas is by air-introduced machine (9)A part is sent to externally heated retort oven(4)Make-up gas fuel, rest part is by air-introduced machine(9)What is be arranged afterwards diffuses temporarily Emptying;
Step 4 is from single stove vertical tube cooler(5), cyclone dust collectors(7)And vertical pipe type inter cooler(8)It is mainly purified back at three The mixes liquid destructive distillation product that receiving apparatus is precipitated, wood tar, wood vinegar separate tank are converged into through pipeline(14), mixture warp in pond Heat exchange, sedimentation, are separated into wood tar slag blanket, wood tar layer and wood vinegar layer;The wood tar of gained is sent into wood tar storage tank (15), sent outside as product;By the wood vinegar of gained through recycling washing pump(13)It send to single stove vertical tube and cools down through pipeline after pressurization Device(5)And cyclone dust collectors(7)It recycles.
