Abstract
The utility model relates to an inflammable gas preparation device, and provides a novel downdraft biomass gasification reactor aiming to overcome the defect that the traditional combustible gas preparation device cannot ensure the stability of a burning layer and a gasification layer. The utility model provides a novel downdraft biomass gasification reactor, which consists of a storage device, a dumbbell-type reaction chamber, a gravity type explosion-proof door, a gas outlet pipe, a grate, a settling chamber, an automatic air supply device, refractory cement, an automatic feeding device, a fire poking door and a soot cleaning door. The feeding operation in the reactor is conducted through the automatic feeding device, so that continuous feeding of raw materials is realized; the larger storage device is arranged; the burning condition of fuel and the burning layer are not destroyed through manual fire poking or automatic fire poking motion, so that continuity and stability of biogas are ensured; the refractory cement is arranged in the dumbbell-type reaction chamber, so that constant reaction temperature is ensured; and air supply is conducted at the laryngeal aperture of the dumbbell-type reaction chamber, so that the reaction temperature is effectively increased and continuity of biogas is ensured; meanwhile, the generated tar oil cracks under high temperature, so that the tar content in the fuel gas is reduced.
Description
Technical field
The utility model relates to the preparation facilities of inflammable gas, is the combustion gas preparation facilities of fuel with biomass such as agricultural crop straw, careless class, Wood wastes particularly.
Background technology
At present, China's agricultural crop straw is burned in a large number or is discarded, causes energy dissipation and environmental pollution, brings heavy losses to society.Rationally utilize agricultural straw resource and bring into play its potentiality present stage agricultural and rural economy Sustainable development is had important practical significance.The fuel that traditional downdraft biomass gasification reaction device uses mostly is high quality raw material such as timber, charcoal, for low unit weights such as agricultural crop straw, careless class, low heat value raw material, adopt traditional downdraft biomass gasification reaction device can't guarantee the stability of zone of combustion and gasification layer and the carrying out of continuous normal gasification always.
The utility model content
The purpose of this utility model provides a kind of novel downdraft biomass gasification reaction device, use low unit weight, low heat value raw materials such as agricultural crop straw, careless class, by the stability that rational feeding device and burner hearth shape guarantee zone of combustion, gasification layer is set, the assurance gasification is normally carried out continuously.
The technical solution of the utility model is: novel downdraft biomass gasification reaction device is made up of storage device 1, dumbbell shape reaction chamber 2, gravity type boat davit explosive door 3, escape pipe 4, fire grate 5, settling pocket 6, automatic air-supply arrangement 7, refractory cements 8, automatic charging device 9, the door 10 that pokes fire, soot door 11; The outlet of automatic charging device 9 is communicated with storage device 1 vertical opening for feed sealing; The door 10 that pokes fire that can lock is located at storage device 1 top; Storage device 1 is tightly connected by fastening piece and sealing member with settling pocket 6; Soot door 11 is located at the lower side of settling pocket 6; Dumbbell shape reaction chamber 2 is fixed in the settling pocket 6; Storage device 1 is communicated with the sealing member sealing by fastening piece with dumbbell shape reaction chamber 2, and the two is detachable; Fire grate 5 is fixed on dumbbell shape reaction chamber 2 bottoms; Automatic air-supply arrangement 7 penetrates settling pocket 6 and links to each other with the throat of dumbbell shape reaction chamber 2, is the reaction chamber air-supply; Gravity type boat davit explosive door 3 is installed on the escape pipe 4 vertically upward; Be provided with refractory cements 8 in dumbbell shape reaction chamber 2 inside.
The beneficial effects of the utility model are: give feed in the reactor by automatic charging device, realize the continuous supply of raw material; The bigger storage device in space is set,, guarantees that fuel combustion conditions and zone of combustion are not destroyed, guarantee the continuity and stability of aerogenesis by poking fire manually or poking fire automatically; Adopt automatic hoop air-supply in zone of oxidation, guarantee that air-supply evenly; In the dumbbell shape reaction chamber refractory cements is set, guarantees that temperature of reaction is constant; The air-supply of dumbbell shape reaction chamber aditus laryngis can effectively improve temperature of reaction, guarantees the continuity of aerogenesis, makes the tar Pintsch process of generation simultaneously, reduces the tar content in the combustion gas.
