Description

Straw biological raw material gas furnace

Technical field

This novel gas furnace that belongs to, relate in particular to a kind of energy-conservation straw biological raw material Multipurpose gas stove.

Background technology

China is a large agricultural country, have abundant biomass energy, its stock number is about 5,000,000,000 ton/years, as agricultural crop straw (straw, wheat straw, rice husk, shell, cavings, weeds), forest discarded object (branch, sawdust, wood shavings, the stem class of each Plants, the leaf class, the root class, the rattan class), industrial organic wastes (the pharmaceutical factory of traditional Chinese medicine, press sugar refinery, the residue of cigarette factory), beast poultry manure etc. is all everywhere, these living beings effective rates of utilization are extremely low, major part is burned or is discarded, both caused serious atmosphere pollution, destroy ecological environment, more it's a pity and wasted valuable resource.For this reason, country clearly emphasizes in playing " People's Republic of China's Renewable Energy Law " of formal enforcement on January 1st, 2006: country encourage clean, develop biomass fuel, encourage growth energy crop efficiently.The development and utilization that " the Renewable Energy Development special fund management Tentative Measures " implemented in 2006 are regenerative resource provides strong fund guarantee.In April, 2007, National Development and Reform Committee has announced " biological industry development Eleventh Five-Year Plan ", point out: " greatly developing bioenergy and bio-based materials; accelerate the extensive use of Biotechnology in high flow rate, high pollution industry; both be conducive to reduce the dependence of China to non-renewable energy resources such as oil, coals; be conducive to again advance cleaner production, reduce pollutant emission, is the important leverage of taking a new road to industrialization, realize sustainable development ".In July, 2007, " the agro-ecology mass-energy industrial development planning (2007-2015) " that the Ministry of Agriculture puts into effect clear and definite proposition especially, build a collection of straw solidification shaped fuel application demonstration pilot project and gasifying stalk central gas supply station, utilize marginality soil optimum development energy crop, meet the raw material needs of country to liquid fuel.In Eleventh-Five Year Plan, also clearly propose " accelerating development the regenerative resources such as wind energy, solar energy, biomass energy ".For Accelerating The Construction conservation-minded society, oneself becomes key subjects the comprehensive utilization of biological renewable energy, is the focus development project that country actively supports always, and puts into effect multinomial policies and measures and help the peasant not burn recycling to stalk.Stalk gasifier project as the biological renewable energy comprehensive utilization, since 86 years, progressively in China, promote the use of, in gasification furnace, in the plant such as straw, contained carbon compound is converted into containing fuel gas such as carbon monoxide (CO), methane and hydrogen (H2), as using energy source.But the emission problem of tar in gasification furnace, formed the inadequate natural endowment of stalk gasifier, and never obtain fine solution, serious impact applying of stalk gasifier project, and in some areas, cause certain economic loss to produce harmful effect.In marketing in the urgent need to a kind of without tar emission, can produce pure combustion gas, igniting and use all easily and has for warming oneself, cook, have a bath and the multi-function ranges of industrial stoving, steam simultaneously.

Summary of the invention

This novel purpose is: provide a kind of biomass material gas processed without the tar multifunctional furnace, utilize straw, wheat straw, corn stalk, branch etc. or compressing raw material to make fuel, directly into stove, once reinforced, can burn by continous-stable, without tar emission, the thermal efficiency is high, combustion gas is pure, and igniting and use are all very convenient, and fuel gas is connected with warming stove, kitchen range, water heater with pipeline by clarifier.

For achieving the above object, this novel technical scheme is: straw biological raw material gas furnace; Its body of heater is comprised of upper and lower body of heater, and the structure of lower furnace body is inside and outside two-layer, and insulation material is equipped with in centre, and the air intake distribution plate is equipped with in the bottom of lower furnace body, the following connection ajutage of air intake distribution plate, and the other end of ajutage is equipped with blower fan.Upper furnace body is housed above lower furnace body, and the shell of upper furnace body is inside and outside 3-tier architecture, and wherein nexine is heat-insulation layer, and the top of upper furnace body is end cover.The back of upper furnace body is equipped with clarifier, and 3 efferent ducts are equipped with in the side of clarifier, connect respectively warming stove, kitchen range and water heater.It is characterized in that: uniform 10 division boards in the inside and outside two-layer centre of upper furnace body, the upper lower curve air flue of composition, the skin of the upper furnace body place corresponding with the division board space is evenly equipped with 5 blow-off pipes, and valve is housed on blow-off pipe.

In order to light a fire, facilitate the Lower Half of lower furnace body to have fire hole and ash output opening.

For the gas that makes output is purer, 10 division boards are equipped with in clarifier the inside, and the division board bottom at interval has the balance water hole, and blowoff valve is equipped with in the clarifier bottom.

This novel beneficial effect is: owing to having adopted 3 layers of body of heater, the upper lower curve air flue that gas forms through 10 division boards, carry out cooling decoking, make the gas of output comparatively pure, through the double purification of clarifier, the gas of output is purer, multifunctional furnace is fuel used not to spend money on and can freely obtain in rural area, fuel enters stove not to be needed to add any chemical assistant, simple to operate, therefore is conducive to popularization and the use of stalk multifunctional furnace.
