Description
Technical field:
The present invention relates to boiler, especially thermal decomposition vaporization biomass fuel, the boiler of co-producing bio-oil, combustible gas, gac, heat energy simultaneously.
Background technology:
At present, biomass fuel utilizes problem to cause the generally attention of countries in the world, carries out every research work, makes certain gains.
Sun power is stored in bioenergy in the biomass by photosynthetic mode, and by growth and occurrence condition, biomass have different kinds, wherein have: 1. the terrestrial plant of self-sow and waterplant; 2. the agriculture byproduct of artificial growth is as stalk etc.; 3. the tail product behind the processing agricultural-food is as rice husk, sugared slag etc.; 4. human tail product (rubbish) after using agricultural-food.These materials, stay in grade has very big energy, can be converted to solid-state, liquid state and gaseous fuel, thereby can satisfy the human demand that obtains heat energy.
Directly firing biomass fuel also can obtain heat energy, but because the energy density of biomass fuel is low, is not easy to store, carries and uses, and can not satisfy the demand of human modern way of life and big industry.The scientific research personnel of various countries is inquiring into the biomass fuel switch technology, bioenergy is converted to other form, at present, the technology of comparative maturity is with behind the biomass fuel thermal decomposition vaporization, make oil fuel and combustible gas with pyrolysis vapour, substitute and additional fossil oil, but present achievement does not also reach the ideal degree.
The core technology of biomass fuel thermal decomposition vaporization technology is a type of heating, and the key distinction of disclosed various embodiments also is the difference of type of heating at present.
Prior biological matter fuel thermal decomposition vaporization technology is to use for reference coal pyrolysis vaporization technology basically, simple heating mode is that the heat that utilizes the part of fuel burning to produce makes the rest part fuel thermal decomposition vaporization, produce thus have in the pyrolysis vapour part be non-flammable smoke components (CN9021843.3), because the weave construction of biomass fuel is fluffy, carry more moisture and gas than coal, the rare gas element that produces after being heated also is mixed in the pyrolysis vapour, so the pyrolysis vapour calorific value that this mode produces is very low, generally can only reach 3.5～7.8MJ/Nm
3(calorific value of Sweet natural gas is 33～42MJ/Nm
3).
In the pyrolysis vapour that this type of heating produces by combustible gas, carry gas (rare gas element that moisture that fuel carries and gas produce), burning gas (supplying with the flue gas that rare gas element that the air of burning usefulness carries and burning produce).
The rare gas element that air carries in the pyrolysis vapour, the mode that has are to adopt oxygen combustion mode (CN97114339.0).
For avoiding the smoke components in the pyrolysis vapour, the mode that has is to adopt the indirect heating mode:
A kind of be thermal barrier type of heating (CN02135649.1) (CN0128480.2), its operational path is:
At first with thermal source carrier (haydite or sand grains) is heated, will enter vaporizing chamber after thermal barrier and the fuel mix then, thermal barrier and fuel heat exchange make fuel intensification pyrolysis, carrier are separated with the fuel tailings again, this mode technical process complexity, and energy consumption is big.
Another kind of type of heating is the indirect heating (CN66212191.4) at vaporizing chamber, and the temperature in this mode vaporizing chamber centre is low.
The indirect heating mode can be avoided burning gas in the pyrolysis vapour, still contains moisture and gaseous product that fuel carries, and the calorific value of pyrolysis vapour can reach 11～20MJ/Nm
3
In sum, present various biomass fuel vapourizing unit and the ubiquitous problem of vaporization technical scheme have:
1. the moisture and the gas that carry of fuel is blended in the pyrolysis vapour, has reduced the quality of pyrolysis vapour.
2. a lot of schemes can not maximize, and output is very low, does not form industrially scalable, and the cost height can't substitute fossil oil.
3. a lot of schemes can not be exported heat energy, and the scheme that has can have watercooling jacket outside the combustion chamber, output cooling tail water, and still, the heat energy (steam) that needs for most user needs supporting gas fired-boiler in addition.
Summary of the invention:
In order to solve the above problems, the invention provides a kind of pyrolysis biomass fuel simultaneously can co-producing bio-oil, the boiler of combustible gas, gac, heat energy, the feeder system of this boiler can be dewatered biomass fuel, outgas, heat up, and makes its energy density reach maximum value; This boiler can be with the fuel fast pyrogenation in hot environment after the preparation, and vapour separates admittedly, produces pyrolysis vapour, but coproduction or per unit area yield bio oil, combustible gas, gac, heat energy (steam or hot water), simultaneously, this boiler also should: the raw material availability height does not produce secondary pollution.
For achieving the above object, technical scheme of the present invention adopts following method to finish:
A kind of pyrolysis biomass fuel can coproduction oil, the boiler of gas, charcoal, heat energy is made up of feeder system, external-heat pyrolysis device, heat exchange type pyrolysis installation, boiler etc.
