Description
Technical field
The utility model relates to vapourizing furnace field, specifically, is a kind of biomass gasifying furnace of energy-conserving and environment-protective.
Background technology
The solid biomass enormous amount that China is available, mainly based on agricultural wastes and timber refuse.Biomass distribution dispersion, collects and transport difficult, under the condition that China is current, is difficult to adopt extensive combustion technology, thus the Biomass Gasification Power Generation Technology of middle and small scale (200-5000kW) in the advantage of state-owned uniqueness.Because China Power is in short supply, and biomass waste waste is serious, cheap, so the cost of Biomass Gasification & Power Generation, be about 0.2-0.3 unit/Kw.h, close to or be better than conventional power generation usage, its specific investment is about 3500-4000 yuan/Kw only, for the 60%-70% of coal electricity, so possess the condition coming into the market to compete.Current China has possessed the ability of building MW level Biomass Gasification & Power Generation project.But technology still exists some problems, the most outstanding is to the secondary pollution of water and strong to all kinds biomass suitability, and systems generate electricity efficiency is lower, and thermo-efficiency is only about 15%.
The straw fuel gas that Biomass energy stove manufactures, belongs to green novel energy source, has powerful vitality.The raw material produced due to plant gas is agricultural crop straw, forest tree castoff, edible fungi residues, cattle and sheep animal manure and all inflammable substances, is a kind of inexhaustible renewable resource.Each peasant household only needs plant material 3-5 kilogram every day, whole day life energy (cooking, heating, shower) can be solved, and burn as liquefied gas, the mode of life that China's rural area smoke fire burns can be changed completely, traditional bavin stove can be banned completely, substitute liquefied gas.
In traditional biomass gasifying furnace, the existence of tar has many-sided disadvantageous effect to gasification, first gasification efficiency is that reduced, the energy of coal-tar middle oil product of gasifying generally accounts for 5 ~ 15% of total energy, and this part energy is difficult to when low temperature be utilized together with inflammable gas, and major part is wasted, secondly tar is condensed into liquid state when low temperature, easy and water, coke etc. combine, stifled air duct, equipment for gasification is run difficulty occurs.In addition, the tar ratio gas being condensed into fine drop is difficult to burn, and easily produces the particles such as carbon black when burning.Utilize equipment to combustion gas, as the infringement such as oil engine, internal combustion turbine is quite serious, this just greatly reduces the utility value of gasification burning.
So the tar produced for gasification, take measure is converted into combustible gas it, both improves gasification efficiency, reduces again the coal-tar middle oil content of combustion gas, improves the utility value of inflammable gas, has decisive meaning to development and popularization gasifying stalk generation technology.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of biomass gasifying furnace of energy-conserving and environment-protective.
The utility model relates to a kind of biomass gasifying furnace of energy-conserving and environment-protective, belongs to vapourizing furnace field.Comprise materials-stored box, body of heater, inner bag, tar adsorption chamber, tar return line, gas line, ash-falling chamber.It is characterized in that: described materials-stored box is arranged on the top of described vapourizing furnace, described inner bag is positioned at described furnace interior, be connected with bottom described materials-stored box, described tar adsorption chamber is arranged on the outlet of described inner bag, described gas line is connected with tar adsorption chamber, slough the tar that gasification produces, export pure combustion gas for user.Described tar return line is connected with tar adsorption chamber and inner bag.Described ash-falling chamber is arranged on bottom described vapourizing furnace, the ashes after biomass collection burning.
As further scheme of the present utility model, described tar adsorption chamber becomes grid type, covers one deck adsorptive catalyst bottom each grid.After tar adsorptive catalyst, reduce the temperature of coke tar cracking, under gravity, flow into circulation tar collecting tank, via tar return line, pass back into vapourizing furnace inner bag.
Compared with prior art, positively effect of the present utility model is:
The utility model exports uncracked tar in combustion gas by absorption, improves combustion gas purity, and then improves fuel gas buring rate.Continue gasification, and combustion by uncracked tar pump around circuit to vapourizing furnace simultaneously, improve the resource utilization of biomass, reach the object of energy-conserving and environment-protective.
