Description

Residents gasifying stalk device

Technical field

The utility model relate to a kind of with carbohydrate such as the Mierocrystalline cellulose in the stalk, hemicellulose, lignocelluloses under certain temperature condition and anaerobic environment, produce CO, H by thermochemical reaction process such as oxidation, reduction, cracking, dryings ₂, flammable mixed gas such as methane, hydro carbons residents gasifying stalk device.

Background technology

At present, the residents stalk gasifier of the rise on the market mostly is water-lute formula stalk gasifier, but following some weak point is arranged: 1. mechanization degree is lower, institute adds material in fact, makes its discontinuity by manually smashing pressure entirely, easily forms the cavity in the combustion processes with inclined to one side, cause the aerogenesis weak effect, ignition time is short, is difficult for long-time aerogenesis fast, uses repeatedly; 2. do not have ash-storing bin, purge mode is also more original, causes the deashing cutoff time long, and deashing is improper, goes out Mars and raw material again easily clearly, easily causes fire failure, more unsuitablely uses combustion gas for a long time repeatedly fast.3. ventilator trunk is thinner, is easily stopped up by lime-ash, does not also adorn trip switch, and the wind effect is given in influence as required.4. furnace bottom, body of heater, bell integral solder add water-lute in the tank of bell, though easy, but very inconvenient in northern area use in winter, as the untimely top cover of not opening that will freeze that discharges water, the use of can't normally feeding in raw material, in addition, tank is sealed under the long-time use combustion gas condition, and the water vaporize water that is heated is dropped into barrel, causes material to make moist seriously, remove the heat that consumes in the stove hall, influence outside the aerogenesis effect, bank up a fire winter and also easily cause material to freeze, dead stove chance increases.5. do not have the tar treatment unit, easily cause secondary pollution.

The utility model content

The purpose of this utility model is the deficiency at existing water-lute formula stalk gasifier, proposes a kind of dry-type encapsulatedly, not limited by envrionment conditions, and aerogenesis is effective, does not have the novel residents gasifying stalk device of tar secondary pollution again.

For achieving the above object, adopt following technical scheme: a kind of residents gasifying stalk device, comprise body of heater, with the bell of body of heater upper surface fixed seal connection and place the furnace bottom etc. of body of heater bottom, a top cover is set on the described bell, the contact position of bell and top cover all adds sealing-ring; Described top cover central authorities are provided with the material compaction apparatus; The uniform compressing tablet that adds of described bell upper surface outer edge; Embed big stove tooth on the described body of heater lower surface, this big stove tooth and support are affixed, and this support and furnace bottom are affixed; Ventilator trunk one termination blower fan, the other end enters the space that is formed by support, body of heater lower surface and furnace bottom, be in the grey storehouse after, its termination connects threeway, another of this threeway is logical to be put grey storehouse central authorities and meets central authorities to airduct, residue one is logical by ventilation duct lower end cover thread seal, and porous places central authorities to give the top of airduct to fan housing and covers central authorities gives behind the airduct affixed with big stove tooth; Described big stove tooth below is provided with the port tooth, and this port tooth is center of rotation with described central authorities to airduct and is placed in the pulley on the support and is installed on central authorities and hold up to the bearing on the airduct; One side of this port tooth connects stay cord, and this stay cord is walked around in the grey storehouse that the stay cord pulley that is fixed on the support is placed on port tooth below, and the opposite side of port tooth is connected with return spring on being fixed in support.

The flange of described material compaction apparatus is fixed in top cover central authorities, it is affixed that bearing and nut are installed on termination and handwheel that flange inner chamber and nut upwards pass behind bearing and the flange successively, screw rod with enter in the furnace chamber downwards after nut thread is connected, the affixed holding pad of screw head in the furnace chamber, affixed reference column on this holding pad, the affixed handwheel in another termination of described screw rod.

Described body of heater inner chamber is up-small and down-big cone, and the Lower Half internal chamber wall is made of the inner core of flame-proof thermal insulation material compression moulding, and first half internal chamber wall is made of iron sheet.

One end of external poker passes described ventilation duct lower end cover and gives in the fan housing to entering porous behind the airduct with the ventilation duct lower end cover is affixed and central, and the other end is passed down through furnace bottom and places the outer termination of furnace bottom to connect one handle.

More optimization is, it comprises that also tar melts down combustion unit, and strainer one end of this device connects the vapor pipe that is communicated with furnace chamber, and the other end is communicated with tar and melts down incendiary pencil, has emptying gasification pipe to meet the user on the described strainer; This tar melts down and control tar is installed on the incendiary pencil melts down switch, and is positioned at porous in its other end and the stove and is communicated with for the tar gasifier above the fan housing.

The gasifying stalk know-why be with carbohydrate such as the Mierocrystalline cellulose in the stalk, hemicellulose, lignocelluloses under certain temperature condition and anaerobic environment, produce CO, H by thermochemical reaction process such as oxidation, reduction, cracking, dryings ₂, flammable mixed gass such as methane, hydro carbons, the core of this technology is exactly to set up the high-temperature gasification district to reduce thermosteresis as far as possible and keep the environment that gasification is temperature required, system sealing realizes quantitatively giving as required wind.The furnace chamber inwall of gasifying stalk part of the present utility model for this reason adopts the inner core of flame-proof thermal insulation material compression moulding to constitute, and prevents that heat scatters and disappears, and has set up the good high-temperature gasification zone, is easy to form required temperature gasification and high and keeps constant; And all junctions of total system all form and are tightly connected, and are easy to control to what of air quantity.In addition, material compaction apparatus of the present utility model makes material stressed evenly, be difficult in the combustion processes forming the cavity and partially, and make the aerogenesis time lengthening, aerogenesis speeds up, gas production rate increases, ignition time is long, guarantees to use repeatedly for a long time combustion gas; Tar melts down combustion unit and has thoroughly solved the tar that the residents vapourizing furnace produced and can't handle, and causes secondary pollution problem; And the junction of bell of the present utility model and top cover seals with sealing-ring, and the top cover of not opening can't normally use and the defective of dead stove in that north of china in winter is easily icing to have solved existing watertight banking; The port tooth not only plays sealing, and staggers with big stove tooth when rotating and realize quick deashing, and the cutoff time is shortened.Above-mentioned beneficial effect is that new approach has been opened up in the comprehensive utilization of agricultural stalk, also is the register one's residence exploitation of engineering of gasifying stalk, and research is laid a good foundation.The utility model satisfies not only that family life is cooked, bathing, heating, is particularly suitable for industrialized agriculture production and heats.
