Description
One, technical field
The present invention relates to the equipment with wood material preparing active carbon, be specifically related to the charcoal activation equipment not needing external heat one one-step physical method preparing active carbon with wood material.
Two, background technology
At present, two kinds are mainly contained: one is the powder raw material such as bamboo bits or wood chip by the method for wood material preparing active carbon, main zinc chloride or phosphoric acid are made activator rotary kiln synthesis by internal resistance electric melting and are prepared powdered carbon, it also exists the problem of waste gas and contaminated wastewater environment, and the area strict in many environmental protection will be restricted; Another kind is that two step steam activation legal system particle or powdered carbons considered to be worth doing by shell or wood (bamboo); it makes fruit shell carbon after needing first to consider shell or wood (bamboo) to be worth doing charing or charcoal considered to be worth doing by wood (bamboo); charcoal is considered to be worth doing for raw material again with fruit shell carbon or wood (bamboo); particle or powdered carbon is made by steam activation method; reactivation process needs extra fuel heating just can reach and maintain the temperature needed for activation, and energy consumption is larger.At present, no matter be that physical activation method or chemical activation method produce gac, all need to consume the fuel such as fire coal, combustion gas or bavin, will by high-temperature activation tail gas by chimney discharged in the air, there is the situation of thermal waste, fuel cost is higher, and additional combustion burning of coal simultaneously produces stack gas and pollutes atmospheric environment.
About the similar patent of wood material single stage method preparing active carbon has: the patent of invention of patent No. ZL201010181027.7, it has been addressed and a step steam activation legal system after formed of xylolite has been got powdered carbon, require wood chip to be pressed into after particulate state again with vertical moving-bed activation furnace preparing active carbon, technique seems and comparatively bothers, and shaping needs of wood chip consumes the energy, application number be 201110337017.2 patent of invention wood chip rotary activated furnace single stage method preparing active carbon and the method for by-product gas, wood raw material one end from rotary kiln adds by it, through super-dry in rotary kiln, charing and activation, from the other end discharging of rotary kiln, there are two point defects: one is that the air-flow of converter flows to discharge end, the feed end temperature of converter is lower, wood chip is dried and charing not easily, thus just combustible gas can not be produced, so be difficult to the feed end temperature raising converter, converter leading portion fails to play good effect, Deng wood chip along with converter rotational conveyance to during temperature higher part position and air meet and easily catch fire and reduce the yield of gac, the drying of wood chip, charing and activation are all carry out at the back segment of converter, region of activation is shorter, soak time in converter is just shorter, thus affect the quality of activation effect and product, two is that the water vapor that wood chip produces in drying process mixes mutually with the inflammable gas produced during charing, can reduce the combustibility of inflammable gas.
Based on above-mentioned background, the utility model develops the charcoal activation equipment that wood material exempts from external heat one one-step physical activation method preparing active carbon, and combustible gas that it utilizes wood material pyrolysis to produce maintains thermal energy balance, need not additional burning coal and environmental protection more.
Three, summary of the invention
The utility model is overcome the shortcoming of current two-step approach preparing active carbon and deficiency, develop the charcoal activation equipment that wood material exempts from external heat one one-step physical activation method preparing active carbon, its content is such: utilize inside and outside sectional type charing converter and revolving activation furnace continuous one-step to prepare gac, wood material first utilizes and adds from external-heat charring furnace the object that hot exhaust gas removal moisture reaches drying in internal heat type converter, the steam produced is drained from chimney with drying medium, avoid mixing with the inflammable gas produced when carbonizing and affect its combustibility, and dried material is fallen in external-heat charring furnace and is carbonized, heating medium is the high-temperature activation tail gas introduced from activation furnace, the inflammable gas produced in carbonization process leads to the inflammable gas produced with activation in activation furnace and mixes, in activation converter, wall is also provided with vapour pipe, pass into water vapor overheated in right amount and charcoal at high temperature to carry out priming reaction and produce the inflammable gas such as hydrogen and carbon monoxide, the interior wall of activation rotary furnace body arranges blast main, pass into appropriate air and gas fuel burning to maintain activation temperature.Priming reaction and combustion reactions formula are respectively:
C+H
2o=H
2+ CO and H
2+ CO+O
2=CO
2+ H
2o
Activation charcoal falls discharging after water jacket cooling in holding tank, the high-temperature tail gas that activation produces is guided in external-heat charring furnace and water vapor superheater, be used for heating charring furnace and preheating water steam, then lead in the dry converter of internal heat type be used for dried feed by make use of the tail gas after partial heat energy.Thus realization carbonizes the inflammable gas all combustion heating activated materials in activation furnace produced in the inflammable gas and reactivation process produced, the water vapor of pre-thermal activation and heating charring furnace is used for again from activation furnace high-temperature activation tail gas out, the heating medium of charring furnace leads to again in dry converter and is used for dried feed, the circulation comprehensive realizing heat energy utilizes, the whole process of producing gac can not need to consume additional fuel, save energy consumption greatly, reduces production cost.
Charcoal activation equipment described in the utility model carbonizes converter by the dry converter of internal heat type, external-heat and internal heat type activation converter is in series, and wood material completes drying, charing and reactivation process continuously respectively through these three converters.This charcoal activation equipment is by bogie wheel (1), feeding spiral conveyer (2), loading hopper (3), the offgas outlet (4) of converter, supporting support roller (5, 11, 21), transmitting gear (6, 8, 19), dry converter housing (7) of internal heat type, activation tail gas adapter (9), blanking groove (10), charing converter housing (12), heating flue (13), heat-resistant layer (14), thermal insulation layer (15), water vapor preheater (16), high-temperature activation tail gas intake (17), activation converter housing (18), blast main or vapour pipe (20, 22), steam manifold and swivel joint (23), discharging flashboard (24), activated material holding tank (25), activation offgas outlet (26) and wind-distributing pipe (27) formed, dry converter housing (7) of internal heat type is pressed in three converters, the order of charing converter housing (12) and activation converter housing (18) is cascaded successively, driven by respective drive-motor respectively and rotate.The high-temperature tail gas activating generation in activation converter is guided in external-heat charing converter and water vapor superheater, be used for heating charing converter and preheating water steam, and then the tail gas after heating charing converter is led to dried feed in the dry converter of internal heat type, the circulation comprehensive realizing heat energy utilizes, and wood material is from drying, charing and activation until the whole production process of activation charcoal does not need external heat source.
