Technical field
The present invention relates to carbonization technical fields, and in particular to a kind of granular substance continuously carbonizing method and apparatus.
Background technique
For environment protection charcoal as a kind of trashformation energy fuel, calorific value is higher than coal calorific value, smokelessly, tasteless, nontoxic, clearly
Clean health, widely used, industry, agricultural, animal husbandry and the industry requirements amount such as civilian are very big.Industrial carbons are mainly concentrated for work
The ginseng of industry material and with charcoal and metallurgy, the carburizing charcoal of chemical industry；Environment protection charcoal is active carbon, carborundum, silicon metal, heat preservation
The row such as the production of material and smeltery, Copper fabrication factory, steel mill, rubber plant, carbn disulfide factory, mosquito-repellent incense factory, explosive factory, Foundry Works
The indispensable raw material of industry, may replace coal or heavy oil burns steam boiler.Environment protection charcoal mainly proposes the contribution of agricultural, Animal husbandry production
High-geotemperature, keeps soil moisture, improvement soil ph and the alleviant as organic fertilizer, at home and abroad agriculture at improvement soil
There is preferable market in industry, animal husbandry field.Sphere of life：People are often with environment protection charcoal heating, barbecue, fuel for chafing dish and south
The effects of frying of tealeaves and tobacco leaf drying etc., in addition charcoal also adjusts room air temperature, humidity and eliminates pernicious gas,
Have become the requirement of people's sphere of life.
China is used as large agricultural country, and every annual output has the more than one hundred million tons of various agricultural stalks, all do not use very much, what is had is straight
Burn-up is connect, burning straw not only pollutes air, it is also possible to cause fire incident.Utilization to stalk is urgently to be solved asks
Topic.With the development of technology, occur serial carbonizing apparatus in the market, stalk can be handled, charing process and obtain
Charcoal and fuel gas.Traditional carbonizing apparatus can generate a large amount of flue gases while to waste resource carbonization treatment, pollute environment,
And production process cannot be carried out continuously.Carbonizing plant, it has been required to temperature is improved by external fuel heating, to reach
Biomass carbonated purpose, consumption fuel is more, increases cost.
Summary of the invention
The object of the present invention is to provide a kind of granular substance continuously carbonizing methods, to solve the dirt of the environment in production process
Dye problem.Meanwhile the present invention also provides a kind of granular substance continuously carbonizing equipment for implementing the charing method.
To achieve the above object, granular substance continuously carbonizing method of the present invention adopts the following technical scheme that：Granular material
Matter continuously carbonizing method, includes the following steps, 1), biological particles enter gasification furnace by gasification furnace charger, and 2), open gas
Change furnace observation window, the biological particles in gasification furnace are lighted, observation window is covered, gasification furnace is made to keep sealing state；3), biological
The smoldering under gasification furnace anaerobic condition of matter material generates a large amount of flue gases, contains fuel gas in flue gas；Flue gas passes through flue
Entered in the cooling equipment of purification by gasification furnace, carries out purified treatment；The powdered carbon that gasification furnace generates is discharged to outside furnace；4) after purified treatment
Flue gas, by admission line be sent into roller carbonizer burner position, light the flue gas, to charing roller heating；5), charcoal
When change drum temperature reaches certain temperature, restarts input and output material auger matched with charing roller, biological particles is made to enter charcoal
Change drums inside；6), biological particles carry out charing process in charing roller, generate in carbonization process and contain fuel gas
Flue gas, the flue gas generated in carbonization process enters the purification by circulating line and cools down equipment, to be carbonized by roller after processing
Machine utilizes；7) biomass charcoal powder for, completing charing is discharged by carbonization machine discharge port.
Further preferably, in step 2), the powdered carbon that gasification furnace generates is discharged to outside furnace by the first water cooling discharging auger.
Further preferably, in step 3), purifying cooling equipment includes spray scrubber, cooling tower, and spray scrubber removes
Water-soluble ashy substance, liquefy tar steam, recycles pyroligneous acid；Gas after water washing passes through cooling tower again, to gas
Body is cooling, removes the water vapour in gas.
Further preferably, in step 6), when the fuel gas that biological particles carbonize generation in roller carbonizer is enough
When providing heat for charing, stop gasifier operation, and close the first valve on flue, so that the flue gas in gasification furnace
No longer enter the cooling equipment of purification；Keep the second valve opening on the circulating line, the flue gas generated in carbonization process
The gas source of burning is provided by purifying cooling equipment processing for roller carbonizer.
Further preferably, when roller carbonizer when the temperature is excessively high, drum rotation speed can be accelerated to shorten carbonization time, Huo Zhezeng
Add feedstock amount, or the by-pass valve on admission line can be opened, and suitably turn down second valve, it is extra to make
Flue gas is discharged and lights.
Further preferably, in step 7), biomass charcoal powder passes through the discharging auger discharge of the second water cooling.
For implementing the granular substance continuously carbonizing equipment of granular substance continuously carbonizing method described above using such as
Lower technical solution：Granular substance continuously carbonizing equipment, including gasification furnace, gasification furnace charger, purification cooling equipment, roller charcoal
Change machine, roller carbonizer include input and output material auger, the burner for carbonizing roller, the input and output material for controlling charing roller, and burner is used
In to charing roller heating, gasification furnace is equipped with openable observation window, and gasification furnace charger is used to add biomass to gasification furnace
Particle, gasification furnace and purifies and is equipped with flue between cooling equipment, and biological particles burn the flue gas of generation in gasification furnace
It is handled into cooling equipment is purified, purifies and be equipped with admission line between cooling equipment and the burner, admission line is used
In will treated by purifying cooling equipment flue gas is sent into burner burning, roller carbonizer and purify between cooling equipment also
Equipped with circulating line, circulating line is used to for the flue gas generated during charing process being sent into and purify in cooling equipment.
Further preferably, the gasification furnace charger is also connected with the first feeding packing auger, the first feeding packing auger be used for by
Expect that the biological particles in area are sent into gasification furnace charger, gasification furnace is connected with the first water cooling discharging auger, the charcoal that gasification furnace generates
