Description
Technical field
The utility model relates to a kind of tar-removing device, particularly a kind of biomass gasified gas tar-removing device.
Background technology
Biomass refer to the various organisms formed by photosynthesis, comprise all animals and plants and microorganism.Biomass energy is sun power is stored in biomass form of energy with chemical energy form, take biomass as the energy of carrier.Biomass are important renewable energy sources, and it is widely distributed, enormous amount.But because its energy density is low, disperse again, so be difficult to focus on a large scale, the reason of this most of developing countries biomass economy low SI just.Biomass gasification technology can realize higher utilization ratio under less scale, and high-grade energy form can be provided, being particularly suitable for rural area, developing countries and regions, so be a kind of important technology utilizing biomass, is an important developing direction.China due to region wide, biomass resource is abundant and supply of electric power is relatively nervous, Biomass Gasification & Power Generation has good life condition and development space, so send out the people energetically in China to open up superiority and the economy that Biomass Gasification Power Generation Technology can embody this technology to greatest extent.The use of fossil oil brings a series of environment, society and political issue, and biomass energy have spatter property, abundance, can recirculation, be easy to store and transport, be convenient to the advantages such as conversion, be therefore considered to one of 21 century new forms of energy most with prospects.
Gasifying biomass is the importance that biomass energy chemical conversion utilizes.Gasifying biomass refers to the conversion process of solid-state biomass raw material at high temperature partial oxidation.This process to be ventilated agent directly to biomass, and biomass change small molecules inflammable gas under the condition of anoxic.Vaporized chemical used is different, and the geseous fuel obtained is also different.Most widely used is at present with air as vaporized chemical, the gas of generation mainly as fuel, for occasions such as boiler, Civil energy-saving cooking stove, generatings.Biomass energy has abundant, cheap, renewable, the feature such as clean, along with holding of Copenhagen, Denmark Global climate change meeting in December, 2009, on the earth, the mineral substance energy consumes rapidly, demand is growing, a large amount of CO2 is distributed in finiteness and use thereof, SO2, the gases such as NO2 and the atmospheric aerosol caused, acid rain, Global warming, the environmental problems such as depletion of the ozone layer cause the thinking of people's profound level again, the development & application of biomass energy causes again the extensive concern of people, and gasifying biomass is a kind of conventional biomass energy switch technology, coal-tar middle oil in gasification is inevitable by product.
At high temperature can there is cracking in tar, in gaseous phase together with gasification gas, but when lower than 200 DEG C, just start to be condensed into liquid, become the sticky oily matter of black, affect that equipment for gasification is stable, safe operation, cause energy wastage, reduce gasification efficiency; And the polynuclear aromatic race in tar ingredients forms serious harm when purifying and burn to environment and human health.To the coal-tar middle oil treatment process taking to be suitable for of gasification gas, reduce the component of tar in gasification gas, improving gasification makings amount, is an important subject of biomass gasification technology.
The treatment process of current biomass gasification tar takes different tar processing method according in gasification gas tar production process, is divided into physical cleaning method and chemical conversion process.Mainly contain the combination that spraying process, bubbling immersion method, dry filter method and several method are suitable.
1) spraying process tar removing and dust
The method of spray is utilized to remove the coal-tar middle oil and dust of combustion gas.In order to improve dust removing effects, some gasification stations load corn cob weighting material in a reservoir, and it can play the effect of filtration.Corn cob should regularly replace, and is dried, and adds in the raw material of vapourizing furnace and burns, and also will prevent the secondary pollution using water simultaneously.
2) bubbling immersion method tar removing and dust
Add a certain amount of sodium hydroxide in water, become dilute alkaline soln, to the organic acid removed in combustion gas, tar and other have foreign material to have good effect.The method of this impurity elimination also will prevent the secondary pollution using water.
3) dry filter removes tar and dust
More by the mode of the tar in dry filter removal combustion gas and dust, putting the corn cob of pulverizing, wood chip, husk or carbon granule as filled out in container, allowing combustion gas extend there through; Or allow combustion gas pass through candle; When fuel gas in use for internal-combustion engine makes fuel, combustion gas, before entering cylinder, allows it by the paper air cleaner core etc. of motor car engine.Some gasification stations, at the strainer of resident's indoor location small-sized efficient, built with the gac that adsorptive type is very strong, are removed the tar in the combustion gas before stove further, have received certain effect, but cost are higher.It is emphasized that the filtering material with crossing must be burnt, preventing pollution environment.
Above several method, or use water to produce secondarily polluted water, or produce the secondary pollution of filtrate.
