The utility model compared with prior art has following advantage: the gas that once can prevent nuisances such as a large amount of carbonateds, sulfurous gas, dust with the second pyrolysis fly-ash separator in the body of heater both sides enters air, causes air contaminated; The inlet pipe that the water vapour of novelty exports the bottom reject bin to becomes vaporized chemical can improve coal gasification efficient, improves output gas quality, burning better with the air mixed that gas blower is blown into; This coal-fired gasification producer can use any coal, has broken through geographic limitation, can both conveniently use in all places, the whole nation, benefits popularization, and this coal-fired gasification producer pollutes little, and the energy is saved in burning fully, is a kind of environmentally friendly machine.

The utility model does not need personnel to wait for, and is applicable to all coals and grass, wood, bavin standing grain, stalk, straw.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the rear view of Fig. 1.

Fig. 3 is the cross-sectional view of body of heater.

Embodiment: in conjunction with the accompanying drawings the utility model is described further.

As shown in the figure, the utility model mainly comprises the gas producer body, parts such as combustion gas cracker, and the into loading hopper 2 of coal is arranged at body of heater 1 top, design has a rotating turnover panel between loading hopper and the body of heater inside, rotates turnover panel operating stick 3 and the coal charge in the loading hopper can be shaken off in body of heater.

Connecting pipe is communicated with intravital vaporizer of stove and catalyzer storehouse respectively to adopt the dust separating cracker 5 of water-seal principle to pass through up and down, be connected with an extra heavy pipe road 6 up and down between the pipeline, one water-sealed valve 19 is installed on the extra heavy pipe road, water-sealed valve is one and is trapezoidal or flaring valve bonnet structure that its surface arrangement that feeds in the water surface has several eyelets.Open and close valve assembly 4 is equipped with at top, extra heavy pipe road, can outwards discharge high-temperature vapor, and the burnt pipe 8 of collection is arranged at bottom, extra heavy pipe road, and the burnt pipe of collection returns tar pipe 9 by one and is connected with inlet pipe 12.

Be designed to the through type flue in the body of heater, stove rod plate 22 is arranged at the flue bottom, and reject bin 10 is arranged between stove rod plate bottom and the base of furnace body, and whirlwind road 23 is arranged in the reject bin, has on its sidewall to lead to the outer ash output hole 11 of body of heater, opens sealed ash output hole and can remove lime-ash.Connect inlet pipe along spirrillum whirlwind road one end that the reject bin inwall is arranged, inlet pipe links to each other with body of heater gas blower outward again.The other end in whirlwind road is connected to below the stove rod plate.Stove rod plate top is catalyzer storehouse 20, is provided with refractory brick blocks 21 between the catalyzer storehouse in stove rod plate and stove, plays the effect that i.e. cooling provides waste heat again.Have a plurality of catalyzer mouths 7 that communicate with the catalyzer storehouse on the furnace body outer wall, catalyzer joins in the catalyzer storehouse by the catalyzer mouth, is vaporizer above the catalyzer storehouse.At the body of heater middle part sealed sight burner 13 is arranged, also can light a fire and remove the gred by this mouthful.

Be communicated with a steam output tube 14 between second pyrolysis device 16 and the inlet pipe 12 that tangentially is installed on the reject bin, water vapour becomes vaporized chemical to be transported to vaporizer in inlet pipe to help combustion-supportingly, increase coal gasification efficient, improve the output gas quality with air mixed that gas blower is blown into.

Second pyrolysis device 16 is designed to automatic inlet chest and places outside the body of heater, and the water inlet pipe valve 17 of connecting supply cold water with running water pipe is arranged at its top, can observe the water level of water tank the inside from the safety level typotron; The output pipe valve 15 of output hot water is arranged at the bottom.

Working process of the present utility model: raw material is added by loading hopper, and gas blower will be blown into the intravital vaporizer of stove as the air of vaporized chemical to be mixed with raw material to burn and promptly produce elementary gas.Elementary gas enters a cracker by the pipeline of upper of furnace body to carry out the first time and filters, reduced particulate matter and dust impurity wherein through this time filtration, can effectively reduce carbonic acid gas and black smoke concentration, become the pure inflammable gas that is cleaned after elementary gas filtration and the cooling, be back to by the pipeline of a cracker bottom and carry out catalyzed reaction in the catalyzer storehouse, its combustion value of the liquid cracked oil of generation is in 3.9-4.1 ten thousand kilojoules.One ton of coal approximately can produce 300 kilograms of cracked oils, output value height, and security is good.The utility model adopts low temperature pyrolyzer, and the cracking working temperature utilizes the waste heat in the burner hearth to meet the demands about 350 degree, and therefore the oxynitride that generates is very low, and environment is not almost polluted.High burning-value inflammable gas after catalyzed reaction enters to be mixed by water cooler and filtering and in the second pyrolysis device that clear device forms coal gas is filtered once more and cool off, and is delivered to user pipe by gas outlet pipe 18 after treatment.The elementary gas-cooled while, separated tar, dust fall into the burnt pipe of the collection that is connected thick tracheae bottom, and the burnt pipe of collection returns tar pipe coupling inlet pipe by one, and useless tar is blown into vaporizer along with the air of inlet pipe and raw material burns.This installs integrated equipment, decomposes tar by cracking, and waste oil is utilized effectively.Become the inflammable gas of high burning-value after the inflammable gas process catalyzer storehouse generation catalyzed reaction, combustion value than traditional combustion exceeds one times, for example, the fuel value of common fire coal reaches more than the 2000-3000 kilocalorie through the fuel value of the high burning-value inflammable gas after the pyrolysis gasification about 1000 kilocalories.
