Description
Technical field
The utility model belongs to system gas equipment technical field, specifically, relates to a kind of biological system gas gasification furnace.
Background technology
In recent years, biological system gas gasification furnace has obtained application to a certain degree.It is to act as a fuel as husk, straw, tendril, wild plant etc. with biological, produces fuel gas such as carbon monoxide in body of heater after the anoxycausis, fuel gas is drawn in body of heater again, introduces in the gas kitchen after purifying and burns.Traditional biology system gas gasification furnace is made of parts such as body of heater, bell, burner hearth, supporting plate and voltage-stablizers, lower end at body of heater has air inlet, the upper end has the gas outlet, the top of body of heater is sealed by bell, burner hearth is positioned at body of heater and is supported by supporting plate, central authorities at supporting plate have ventilation and fall the through hole that slag is used, and the top back-off of this through hole has voltage-stablizer.Blower fan is blown into air in the body of heater from air inlet during use, and air-flow passes supporting plate and voltage-stablizer from bottom to top successively, and redox reaction takes place the bio-fuel oxygen supply in burner hearth, produces fuel gas such as carbon monoxide.Because the air intake mode is served as reasons down upwards and what enter is cold wind, and the combustion zone in the burner hearth that seems is less, the time ratio that redox reaction takes place is shorter, and system gas effect is undesirable, and the user has to frequently to burner hearth Nei Jiachai, and it is comparatively inconvenient to use.In addition, bio-fuel burning back carbon ash content is from poor effect, and the carbon ash not only influences intake attached on the voltage-stablizer, and the user also must tool using disclose it, makes it to fall into bottom of furnace body together with lime-ash, draws out cleaning again.In the process of decarbonizing, very easily cause voltage-stablizer to damage, make use cost increase; Not only bother and draw grey mode, and speed is slow, has strengthened user's workload.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of active combustion zone in the burner hearth, carbon ash content of can enlarging from biological system gas gasification furnace completely.
The technical solution of the utility model is as follows: a kind of biological system gas gasification furnace, comprise body of heater, bell, burner hearth and supporting plate, wherein the top of body of heater is sealed by bell, on the wall of body of heater upper end, have the gas outlet, burner hearth is positioned at body of heater and is supported by supporting plate, the middle part of this supporting plate offers through hole, and its key is: be placed with grate above described through hole, this grate is positioned at burner hearth and is supported by supporting plate; The upper end of described burner hearth and the inwall of body of heater recline, its lower end is up big and down small cone structure, form the annular heat air compartment between this cone and body of heater and the supporting plate three, the lower end of hot blast chamber communicates with the external world by the air inlet on the furnace body wall, and the top of hot blast chamber is communicated with the inner chamber of burner hearth by the nozzle of being located on the burner hearth.
The utility model in use, it is indoor that blower fan is blown into hot blast with air from air inlet, make it heating, spray into burner hearth cavity by nozzle again, air-flow moves towards the direction of burner hearth cavity center line, and spreads oxygen supply up and down simultaneously, has enlarged active combustion zone in the burner hearth so greatly, correspondingly prolong the time of redox reaction, avoided the user frequently to add the disadvantage of bavin; After the bio-fuel in the burner hearth burns a period of time, burner hearth has higher temperature, the air that continues to be blown into from air inlet sprays into burner hearth cavity again after heating up under the burner hearth heat transfer process, further ensured the carrying out of redox reaction, makes that system gas effect is better.Grate can adopt rural households with coal stove grate structure, not only simply but also durable.Grate is positioned at the below of nozzle, and grate combines with the conical section of burner hearth, makes that the intake in the burner hearth is unaffected, and bio-fuel burning back carbon ash content is from thoroughly.
For enlarging active combustion zone in the burner hearth as far as possible, prolonging the redox reaction time, 3～5 nozzles are installed on the top of above-mentioned burner hearth conical section, each nozzle is located in the same horizontal plane and evenly distributes on circumference.
On the base plate of above-mentioned body of heater, be fixed with two blocks of parallel relative " L " shape slide rail plates, be placed with ash discharge on the two slide rail plates and take out case, this ash discharge take out case be positioned at grate under and can slide along the slide rail plate.The lime-ash that bio-fuel burning produces falls down from grate, falls into ash discharge and takes out case, after ash discharge is taken out and collected full lime-ash in the case, extracts out to outwell from two slide rail plates and get final product, has not only made things convenient for but also the piece victory.
Beneficial effect: the utility model can enlarge active combustion zone in the burner hearth, prolong the redox reaction time, it has been eliminated the traditional structure user and must frequently add bavin and draw the disadvantage that ash bothers, and can guarantee that the unaffected and bio-fuel burning back carbon ash content of intake in the burner hearth from thoroughly, has characteristics such as reasonable in design, simple in structure, easy to use.
