Background technology

Along with science and technology development, utilizing living beings to prepare clean fuel gas is the system engineering that an economic benefit and social benefit have concurrently.The living beings gasification is to utilize the heat chemistry principle, is that medium generates imflammable gas under the condition of anoxic with air and steam, becomes operable clean fuel gas through after the corresponding purified treatment.At present, the gasifying stalk device is owing to be subjected to integrally-built restriction, and it is low mostly to exist gas production, and fuel gases calorific value is low, characteristics such as tar content height.The inevitable industrialized development that suppresses straw fuel gas to a certain extent of above-mentioned factor.

The utility model content

The utility model is intended to overcome the deficiencies in the prior art part and a kind of gas production height is provided, and tar content is low and have a gasifying stalk system of higher fuel gases calorific value.

For achieving the above object, the utility model is achieved in that

A kind of gasifying stalk system comprises that body of heater, clarifier, inside is equipped with polishing filter, air accumulator that the cooling filter of aqueous medium, cyclone filter, inside are equipped with filter material; Described body of heater comprises upper furnace and is furnished with the lower hearth of gas outlet; Described gas outlet communicates with the air intake of clarifier through pipeline; The gas outlet of described clarifier communicates with the bottom of cooling filter; The gas outlet of described cooling filter communicates with the air intake of cyclone filter; The gas outlet of described cyclone filter and polishing filter; The gas outlet of described polishing filter communicates with the air intake of air accumulator through blower fan.

As a kind of preferred version, can be furnished with the reinforcement flue in the body of heater described in the utility model; Described flue and furnace wall connect and constitute the preheating steam chamber; Is furnished with the venthole that communicates with upper furnace on described preheating steam chamber top; Around described flue, be provided with economizer bank; The inlet of described economizer bank connects water filling port; The gas outlet of described economizer bank communicates with the preheating steam chamber through appendix.

As another kind of preferred version, is furnished with the labyrinth type dividing plate in the utility model cooling filter.

As the third preferred version, can be furnished with spray thrower in the clarifier described in the utility model.

As the 4th kind of preferred version, is furnished with water seal between blower fan described in the utility model and air accumulator.

Can be provided with in the bottom of described lower hearth as the 5th kind of preferred version and to purify waste water.

The utility model gas production height, tar content is low, and has higher fuel gases calorific value.When system moves, because the high-temperature region is in the bottom of flue, required preheated air can enter the preheating steam chamber after the economizer bank heating, hot-air carries out secondary heating in the preheating steam chamber, be injected in the flue by venthole again after making steam reach superheat state, contact with the charcoal layer fully and carry out pyrolytic gasification reaction.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is an overall structure schematic diagram of the present utility model.

The specific embodiment
