Description
Technical field
The utility model relates to heating plant, especially a kind of biomass semi-gasification domestic boiler.
Background technology
More existing stove outer coverings have the domestic briquet stove of intercalated water sleeve, hot water in coal burning naked light heat and the intercalated water sleeve can be provided simultaneously, for improving the thermal efficiency, some coal stove also has the sintering of returning structure, chimney promptly is set on body of heater, the chimney periphery is provided with the chimney water sleeve that is communicated with burner hearth water jacket on every side chimney is encased, the bottom of chimney and the open top of burner hearth are by returning the burning channel connection, unburnt combustible gas that produces in burner hearth like this and combustible can return burning from top to down, with the heating surface area that improves water jacket and improve the thermal efficiency, in addition, existing domestic boiler generally acts as a fuel with the wherein a kind of of coal or biomass fuel, and can not use this two kinds of fuel simultaneously.More than these boilers or coal stove or biomass gasifying furnace can only be in position burning near burner hearth bottom, and its burner hearth structural limitations of originally experiencing, the roof of the furnace oxygen delivery capacity is relatively poor, cause the thermal efficiency lower, even still have a large amount of uncombusted materials after the burning and can discharge from chimney with flue gas through returning, so not only cause energy waste, and have a large amount of objectionable impurities and discharge and contaminated environment from chimney.
The utility model content
The purpose of this utility model is to provide a kind of thermal efficiency height, but flue gas second-time burning and make the little biomass semi-gasification domestic boiler of smoke pollution.
The technical solution of the utility model is: the biomass semi-gasification domestic boiler, be provided with the combustion chamber in the body of heater, side, described combustion chamber is provided with vaporizer, in the body of heater in the combustion chamber, vaporizer around be arranged with the water jacket of hollow sandwich structure, vaporizer communicates with the bottom of combustion chamber.
Around being distributed with the secondary air through hole, between the combustion chamber locular wall at secondary air through hole place and body of heater, leave the secondary air gap of annular on the locular wall of described top of combustion chamber, offer the secondary air distribution outlet that communicates with the secondary air gap at the body of heater middle part.
The combustion chamber locular wall at the secondary air through hole place of described top of combustion chamber is up-small and down-big cone-shaped hood.
Be provided with by-pass flue in the described body of heater, be arranged with water jacket around the by-pass flue, also be provided with in the body of heater and return the burning air flue, return the upper end of burning air flue and communicate, return burning air flue lower end and communicate with the bottom of by-pass flue with the fire door of top of combustion chamber opening part.
Described by-pass flue top is provided with the injection pipeline that an end communicates with by-pass flue inside, and the other end of injection pipeline communicates with the top open part of combustion chamber.
Described returning burnt between the water jacket that air flue is arranged at combustion chamber and by-pass flue opposite side on every side.
Be provided with the vaporizer that the bottom communicates with the combustion chamber in the body of heater of the present utility model, can put into the material that biological material, waste plastics, scrap rubber etc. at high temperature are cracked into fuel gas in the vaporizer, vaporizer is provided with near the combustion chamber, material cleavable under the high temperature action of combustion chamber in the vaporizer is that fuel gas enters combustion chamber participation burning again from the bottom, make fuel abundance in the combustion chamber, heat is higher, and produced simultaneously high heat is more conducive to the cracking of material in the combustion chamber.
In addition, the utility model is provided with secondary air distribution structure at top of combustion chamber, the secondary air distribution outlet can be regulated intake as required, to improve the oxygen-supplying amount in top of combustion chamber zone, the fuel gas that makes the generation of a large amount of bottoms is at the top of combustion chamber sufficient combustion, thereby raising efficiency of combustion, reduce tail gas pollution, the secondary air gap of annular and match around being distributed with the secondary air through hole, the oxygen that makes the secondary air distribution from around enter in the burning, make the secondary air distribution can cover the whole zone of top of combustion chamber, make oxygen supply abundant, exhaust combustion is more complete.
In addition, the combustion chamber locular wall of stating the secondary air through hole place of top of combustion chamber of the present utility model is up-small and down-big cone-shaped hood, this cone-shaped hood can be assembled the flue gas that the combustion chamber produced to the higher center of heat, and the flow velocity of reducing smoke is to prolong burning time, thereby make the second-time burning of flue gas more abundant, tail gas pollution is littler.
In addition, lead in the by-pass flue of the present utility model and between the top of combustion chamber opening and be provided with the injection pipeline, this injection pipeline is communicated with by-pass flue with the combustion chamber, the by-pass flue top is had and the similar high temperature of top of combustion chamber, when the combustable gas concentration in the by-pass flue is big, the gas that can be ignited in the by-pass flue by induction tunnel burns away, thereby makes burning more abundant, and tail gas impurity still less; When the fire door of combustion chamber is closed and when banking up a fire, it is outdoor that the tail gas of combustion chamber is discharged through chimney by by-pass flue under the swabbing action of induction tunnel, and can not leak into indoor polluting or gas poisoning, is more suitable for family and uses.
Because combustion chamber heat efficient height of the present utility model, and have to return and burn air flue, by-pass flue, injection pipeline etc. and return sintering structure and secondary air distribution structure, the fuel gas that gasification furnace produced fully can be burnt, and can not produce a large amount of smoke pollution environments, vaporizer can be the high combustion chamber of the thermal efficiency sufficient fuel gas is provided simultaneously, the combustion chamber can not extinguished because of lack of fuel, and both complement each other.
