Description

Living beings low-carbon (LC) stove

Affiliated technical field

The present invention relates to agricultural crop straw comprehensive utilization, be with farming, woods, herd discarded living beings through limit oxygen combustion and pyrolysis reaction conversion be fuel gas directly burning be used for a kind of gasification furnace that cooking is warmed oneself.Especially domestic direct-firing gasification stove.

Background technology

At present, gasification furnace of the prior art is simple in structure because of it, and is cheap; Stalk resource is extensive, and because of global concern energy crisis with because of atmosphere polluting problems that agricultural wastes caused such as seasonal crop straw burnings, party and state pays much attention to the development and use of regenerative resource again; Encourage the stalk energy, advocate the low-carbon (LC) life, to alleviate China's energy shortage situation; Strive for not only energy-conservation but also environmental protection, so product receives having deep love for of rural subscribers and expects very much.But, also, apply thereby restricted it often because of the condensed water spill and leakage causes secondary pollution because gasification furnace of the prior art is handled unclear blocking pipe and kitchen range because of tar; The inventor has had new breakthrough and innovation again through development test repeatedly on the basis of former technical scheme of declaring.

Summary of the invention

After adopting minute body device purification more, existing gasification furnace is delivered to kitchen range confession burning structures through pipeline for overcoming again; Thereby cause combustion gas on the way gradually cooling make wherein tar and the deficiency of steam condensation deposition blocking pipe and kitchen range; The technical scheme that the present invention adopted is: directly on burner hearth (12) top long-neck cracking tube (3) is set and is connected with vertical running through of combustion chamber (1); And it is in aggregates with the body of heater combination; The vaporific combustion gas of high temperature in the burner hearth need not through pipeline output burner hearth; Under the hot environment of being cooled off as yet, directly rising gets into long-neck cracking tube, after bocca is sent to the combustion chamber, has reached the purpose of no longer stopping up because of the condensation deposition through further intensification cracking.

For overcome existing gasification furnace when reinforced because fuel is meticulous or an addition is too much; The deficiency that causes anoxic that the interior flare of burner hearth is extinguished easily and cause smoldering; The technical scheme that the present invention adopted is: in burner hearth (12) wall inboard or arranged outside protect fiery device (11), it is one and can makes with square tube or pipe, also can with the burner hearth all-in-one-piece air duct of casting; Can be provided with several air admission holes in its direction in burner hearth; Communicate with the external world in its bottom or the outside, be convenient to get into combustion air, prevent that in order in time reaching anoxic from extinguishing the purpose of smoldering to oxygenating in the burner hearth.

The time can distribute the not clean-burning pernicious gas of a part and the tar pickup the bottom of a pan and influence cleaning and health in burning in order to overcome its kitchen range of existing gasification furnace; The technical scheme that the present invention adopted is: secondary air passage (10) and secondary air preheating chamber (13) are set; Through replenish the secondary combustion air and to its utilize behind heat temperature raising in advance principle that hot-air upwards flows and the inside that makes hot-air constantly pour in long-neck cracking tube (3) in a steady stream under the draft effect of smoke evacuation tube from secondary intake opening (14) with spray to the combustion chamber from bocca (16) after the fuel gas of burner hearth ejection mixes; Improve combustion zone temperature; Reach clean-burning condition, thereby solved above deficiency.

Existing gasification furnace is many to be arranged at upper furnace with charge door in order to overcome; When take off lid when reinforced flue gas in the burner hearth can overflow deficiencies such as causing room air pollution outside the stove; The technical scheme that the present invention adopted is: one side setting communicates with burner hearth in the body of heater middle and lower part loading hopper (6) or charge door; In conjunction with having adopted sealed pot frame or pot circle; Whole combustion chamber forms air-tight state after putting pan, can be by means of the suction draught of smoke evacuation tube with the air-flow in combustion chamber and long-neck cracking tube and the burner hearth to outdoor withdrawing, the air that opens the door when reinforced is from charge door suction burner hearth and can not overflow flue gas again.

The invention has the beneficial effects as follows through combustion chamber and long-neck cracking tube directly are arranged at upper furnace, reached no longer purpose because of condensation deposition blocking pipe and kitchen range eye; Long-neck cracking tube and secondary air passage and the combination of secondary air preheating chamber be provided with improve the cracking zone temperature and to ensure combustion-supporting oxygen supply sufficient; Help realizing abundant burning, thoroughly solve tar and condensed water pollution problem, improved the thermal efficiency, eliminated pungent smell; Adopt closed pot frame to pull out under the effect of wind-force at the smoke evacuation tube; Being engaged in the body of heater middle and lower part is provided with loading hopper and can forces pernicious gas to take out to outdoor from smoke evacuation tube; Can reach and take off lid and do not have flue gas when reinforced and overflow, guarantee that room air is not contaminated, ensured safe handling and health; Through in the burner hearth inboard or arranged outside protect fiery device; From then on no longer, reinforced meticulous too much anoxic causes smoldering because of extinguishing flare; Ensure the normal combustion aerogenesis, eliminated trouble and worry, help energy-saving and emission-reduction, realize applying of low-carbon (LC) life and new socialist countryside construction.
