Biomass gasifying furnace

Technical field

The utility model relates to a kind of vapourizing furnace, relates in particular to a kind of biomass gasifying furnace.

Background technology

China's available solid biomass enormous amount is mainly based on agricultural wastes and timber refuse.Biomass distribute to be disperseed, collect and the transportation difficulty, so these wastes having slatterned in vain just, and caused environmental pollution.At China present rural energy structure (straw fuel gas, Sweet natural gas, liquefied gas, biogas, sun power, electricity, raw coal, honeycomb briquette, former plant fuel) in the middle of, have only that straw fuel gas is most economical, most convenient, the most energy-conservation, the most suitable, not only safe in utilization, and sanitation and hygiene.The combustion gas of biomass gasifying furnace can be burnt as liquefied gas, can change the mode of life that China's rural area smoke fire burns fully, can ban traditional bavin kitchen range fully, the replacement liquid gasification.Therefore, apply biomass gasifying furnace, meet the national policy that promotes resource-conserving and environment-friendly society.

Multiple biomass gasifying furnace is arranged in the market, and following some is not enough but existing vapourizing furnace exists: 1, the vapourizing furnace volume is little, the very little or aerogenesis not of coarse fodder gas production rate; 2, peculiar smell is big, and tar is arranged, blocking pipe, cleaning difficulty; 3, single airduct ventilates in the body of heater, and fire burns from inside to outside, and efficiency of combustion is low, need disclose several holes with the column of flame, and fire just can burn up, troublesome poeration, and fuel can not fully burn, and caused waste; 4, when igniting cigarette smoke the people greatly, the eyes of choking; 5, burn in the middle of the use empty built on stiltsly easily, must disclose the material compacting, the flue gas people that chokes of leaking, harmful.

Summary of the invention

Technical problem to be solved in the utility model is to overcome above-mentioned deficiency, provides a kind of gas production rate big, and peculiar smell is little, the efficiency of combustion height, and fuel can fully burn, and the biomass gasifying furnace of environmental protection and energy saving.

The technical solution of the utility model: a kind of biomass gasifying furnace, it includes the vapourizing furnace producer, the main pipe line blast pipe, igniting and ash output hole, blast pipe, spray holes, escape pipe, blower fan, secondary wind inleting tube, the cleaner tube, escape pipe and water vent, vapourizing furnace is provided with the main pipe line blast pipe, be provided with the blast pipe that is connected with the main pipe line blast pipe in the vapourizing furnace producer, the inner side-wall of blast pipe is provided with spray holes, also be provided with igniting and ash output hole on the vapourizing furnace producer, one side of vapourizing furnace producer is provided with escape pipe, escape pipe and secondary air pipe coupling, be provided with blower fan between escape pipe and the secondary wind inleting tube, secondary wind inleting tube is connected with the cleaner tube, the cleaner tube is provided with escape pipe, and the below of cleaner tube one sidewall is provided with water vent.Described secondary wind inleting tube is 3cm apart from the distance of cleaner tube bottom.Described blast pipe is circular, evenly is provided with the spray holes more than 2 on the inner side-wall of blast pipe.

The utility model compared with prior art has following beneficial effect: 1. multi-use, can heat, and cook, heat up water, take a shower; 2, Device-General does not change original heating installation, and pipeline, radiator are general, utilize water cycle to reach heating effect, long service life; 3, blast pipe is provided with a plurality of spray holes, has improved efficiency of combustion, and fuel can fully burn; 4, peculiar smell is little, and tar can burn more fully through after-blow, can not produce waste; 5, fuel less energy consumption, cost is low, and raw material sources are extensive, never exhausted, the flammable farming of desirable everywhere (as: husk, cornstalk, rice straw, straw, sesame stalk, Pericarppium arachidis hypogaeae, branch, sawdust, weeds etc.) all biomass, woods waste not only can be turned waste into wealth, and be helped environment; 6, the fuel gas production rate is big, and the time is long, uses biomass 3-5 kilogram every day, just can solve one day life cooking, and heating is had a bath etc., and with producing with usefulness, boiled water flask will be saved 3-5 minute than liquefied gas; 7, safe in utilization, sanitation and hygiene do not have waste gas to get rid of, and can the person not damaged because of the waste gas that burns the coal eliminating; 8, widely applicable, be fit to particularly to cook at home in vast rural area, cooking, heat up water, bathing, heating etc., be fit to also simultaneously that burning boiler, booth are heated, big area heating and school, sub-district, factory, middle refreshment bar use, and is not subject to seasonal restrictions, all can use throughout the year.

Learn according to Shanxi Prov. Agriculture Mechanical Test Appraisal Station's test manufacture identification and detection report: the carbon monoxide content in the smoke evacuation is 0.1%; Combustion noise 53dB (A); The ignition trigger time is 7min; Once reinforced back continual and steady combustion time of 260min; Vaporization rate 65%; Tempering does not take place when working in combustionproperty under 0.5 times of rated pressure, do not take off fire and yellow flame when working under 1.5 times of rated pressures; Thermo-efficiency is 48%; Gas production rate is 1.2m ³/ Kg.
