Compared with the prior art, the biomass gasification furnace has the advantages that the thermal decomposition furnace and the filter are arranged into an integrated structure, the structure is compact, the space is saved, and raw materials are saved in the manufacture; the furnace cover is arranged into the water closing type seal and the smoke and gas do not leak, the sealing performance is good, the air generating efficiency is improved; and the air return pipeline is arranged, when a large amount of fuel gas does not need, the air return pipe switch is opened so that part of air returns to the inside of the thermal decomposition furnace, thereby further saving energy.

Description

A kind of biomass gasifying furnace

Technical field

The utility model relates to a kind of cooking a meal and uses the kitchen range stove, especially relates to a kind of biomass gasifying furnace.

Background technology

Biomass energy is the important energy source that the mankind depend on for existence always, and it is to be only second to coal, oil and natural gas and the energy that occupy the 4th of world energy sources total quantity consumed, occupies critical role in whole energy resource system.Scholarly forecast, biomass energy will become the important component part of following sustainable energy system, and to the middle of this century, the various living beings alternative fuel of producing of employing new technology will account for more than 40% of global total energy consumption.

China is a populous nation, is again a country that economy develops rapidly.Along with the improvement of village economic condition, infrastructure constructions such as rural transport, communication, house have obtained develop rapidly, but straw, Chai He etc. remain the main energy sources that vast farmers is cooked, warmed oneself.For a change backward with the energy mode that straw, Chai He etc. cook, warm oneself directly burnt in the rural area over the past thousands of years, in the last few years, study, develop, utilize biomass energy, its scientific and technological achievement that becomes reproducible clean energy resource is continued to bring out, and wherein the development and use of biomass gasification technology occupy quite great proportion.Biomass gasification technology is biomass materials such as stalk kind, careless class, shell class, bavin standing grain class to be burnt under anaerobic condition and the energy conversion process of reduction reaction, and it is rapidly, continuously with carbohydrate cracking in the raw material and Synthin fuel gas again by technique device.Disclosed at present biomass gasifying furnace, pattern is a lot of, and it is what to separate that its pyrolysis oven of considerable gasification furnace and filter are wherein arranged, and middle is connected by pipeline, and this connected mode both took up space, waste material again on making; Also there is considerable gasification furnace to have the bell poor sealing performance in addition, the problem that cigarette becomes flat occurs leaking.

Summary of the invention

One of technical problem to be solved in the utility model provides a kind of compact conformation, the biomass gasifying furnace that pyrolysis oven and filter become one; Two of the technical problem that solves provides the good biomass gasifying furnace of a kind of pyrolysis oven bell airtight performance.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of biomass gasifying furnace, comprise pyrolysis oven, filter, the escape pipe formed by flue, heat-insulation layer, furnace shell, grate, bell, blast pipe, the sidewall and filter one sidewall that are characterized in pyrolysis oven are close together, and its tight junction is provided with passage and communicates; The pyrolysis oven fire door is provided with ring-like tank, and the bell periphery cover is in ring-like tank.

The utility model also has following feature:

Lower end at filter is provided with three-way pipe, and the pure qi (oxygen) in an end of three-way pipe and the filter communicates between storing, and the other end communicates with blast pipe and makes it become muffler, and an end is a wastewater discharge pipe in addition, is equipped with gauge tap on three-way pipe.

Compared with prior art, advantage of the present utility model is pyrolysis oven and filter are arranged to integrated, and more compact structure has been saved the space, has saved raw material on making; It is airtight that bell is arranged to hydrolock, can not run cigarette gas leakage, and good seal performance has improved gas producing efficiency; Be provided with the muffler pipeline, when not needing to use very big combustion gas, can open the muffler switch, allow portion gas be back in the pyrolysis oven, further saved the energy.
