Description
1, technical field
The invention belongs to the charings of carbonaceous organic material, especially suitable for the charing of agricultural stalk waste, are also applied for wrapping
Include the charing of the abandoned biomass such as municipal sludge.
2, background technique
China's agricultural production at present generates agricultural crop straw every year and exceedes 1,000,000,000 tons, except direct returning to farmland, fodder, energy,
Materialized equal outside, there are also a large amount of agricultural crop straws to abandon by unordered burning or arbitrarily.Serious atmosphere pollution is autumn and winter mist
One of haze main reason.
Experiments have shown that 3t stalk, through carbonizing, available straw charcoal about 1.5t, stalk vinegar liquid about 1t, pyrolysis gas is about
200Hm3, bio-oil about 100kg.
Straw charcoal is a kind of solid, porous particles substance with height aromatization, rich in carbon.It contains a large amount of carbon
With plant nutrient substance, contain more oxygen-content active group with pore structure abundant, biggish specific surface area and surface,
It is a kind of multifunctional material.It can not only improve gas permeability, the water-retaining property of soil, and increasing fertilizer efficiency has slowly releasing effect to fertilizer,
The heavy metal and organic pollutant in soil or sewage can be adsorbed, and there is preferable fixed function to carbon nitrogen, is applied to soil
In earth, it is possible to reduce CO2、N2O、CH4The discharge of isothermal chamber gas, slowing global warming.Therefore straw carbon returning to the field is optimal
A kind of straw utilization ways.
Trimerization company, China is conceived to " being originated from agricultural, peasant is benefited in back feeding farmland ", " the straw biomass charing of proposition
The Strategic Thought of comprehensive cyclic utilization " system engineering, using rotary furnace as charing main equipment.Unfortunately, due to there is wood
Vinegar liquid " taking library " problem, makes to build up at home and the tens of sets revolution retort to put into operation is halted by local environmentally friendly authorities.
To solve this problem, as with complete suitable meter, applicants have invented a kind of rotary charings of biomass for only generating substance charcoal
Furnace.However this invention, inherent defect existing for rotary furnace is not solved fundamentally.
There are a variety of type of furnaces from being born over 200 years in solid fuel charring process, from the retort oven of early stage interval, to company
Kinds of processes and the equipment such as continuous rotary furnace, vertical shaft type furnace, moving bed solid thermal carriers, microwave retort ....But it can be carried out quotient
Industry operation only there are two types of, i.e., processing dusty raw materials rotary furnace and processing block stock vertical shaft type furnace.Shaping raw material is all
It is preferential to select vertical shaft type furnace, this is because vertical shaft type furnace has unrivaled advantage than rotary furnace.For this purpose, applicant is for biology
The charing of matter has invented " a kind of internal combustion type biological particles material is dry, carbonizes, activation integral furnace ", has been exactly using vertical shaft type
Furnace.
However there are still some flaws for this invention: 1 material is walked outside pipe, is also easy to produce blanking unevenness and dead angle, bridging occurs,
Blowing out is needed to clear up；Although 2 setting sealing gland sections, but still imprecision, it may occur that pyrolysis gaseous products scurry into dryer section or flue gas is altered
Enter to carbonize section；3 pyrolysis gaseous products are all sent to condensation cooling recovery system, and the wooden vinegar cannot be regulated and controled with the market according to wood vinegar
The yield of liquid.
3, summary of the invention
The technical problem to be solved in the present invention is to provide a kind of vertical shaft type tubulation retort, can solve above-mentioned " in one kind
Flaw existing for the drying of combustion biological particles material, charing, activation integral furnace ".
The invention is realized by the following technical scheme:
A kind of vertical shaft type tubulation retort, is made of, it is characterised in that drying oven is provided separately drying oven and retort
