Description
Technical field
The present invention relates to a kind of gasification furnace, especially Novel tar-free stove integral gasifier.
Background technology
At present, the energy source of living beings is important regenerative resource in solar energy, and its efficient application will play important supplementary function to improving China's energy resource structure and sustainable development.China's biomass energy sample volume is large, and available resource is also quite abundant.Only take stalk as the example whole nation namely has 1,000,000,000 tons, there are 6.5 hundred million tons to can be used for energy purposes.Gasification of biomass can reduce the greenhouse effects problem that fossil energy consumption brings simultaneously, and is significant to human from now on long term growth and living environment.Under the strategy of nation-building resource-conserving and friendly environment society is guided and under the encouragement of " Renewable Energy Law ", biomass gasification technology and industrialization running have good development prospect.Applying as realizing China's Sustainable Developmentof Rural Economy of this technology, reform rural energy structure improves the life of farmers level, promote the rural society civilization and progress, dwindle Rural-urban Gap, promote the urbanization of villages construction, improve the ecological environment, energy-conserving profit can wait and all play important function.But because gasification furnace of the prior art because of tar problem blocking pipe and kitchen range, also often because condensed water elimination causes secondary pollution, is applied thereby restricted it.
Summary of the invention
Technical problem to be solved by this invention provides a kind of once reinforced sustainable burning, without the Novel tar-free stove integral gasifier of tar emission.
For addressing the above problem, a kind of Novel tar-free stove integral gasifier of the present invention is characterized in that: this gasification furnace comprises updraft type gasification furnace body of heater and the annular tar cracking device that is provided with the Pintsch process burner; The top of described updraft type gasification furnace body of heater is provided with bell, middle part and is provided with feeder, bottom and is respectively equipped with annular tar cracking device and combustion zone and is provided with air inlet pipe for airduct II, a side; Described annular tar cracking device communicates with described air inlet pipe, and be provided with successively drying layer from top to bottom, dolomite catalytic pyrolysis layer, charcoal catalytic pyrolysis layer; Below, described combustion zone is provided with ash hole; The outside of described Pintsch process burner is provided with the gas-cooker inwall, and its bottom is provided with the fire-resistant air distribution ring of taper, and its bottom one side is provided with the horn snorkel with return duct or backflash, and this snorkel links to each other with described air inlet pipe; The fire-resistant air distribution ring of described taper is provided with the kitchen range core with venthole; Described kitchen range core top is provided with infrared ray guard, smoke exhaust pipe, is provided with built-in combustion gas mixing chamber for public attention under it; Described horn snorkel and described backflash all communicate with described combustion gas mixing chamber; The described public attention that supplies is by communicating for airduct II with described for airduct I; Described infrared ray guard and described kitchen range core all are connected with electronic lighter.
Described Pintsch process burner is cylindrical.
Described for public attention and described for being provided with wind control valve I between the airduct I.
Described for airduct I and described for being provided with wind control valve II between the airduct II.
The described airduct I that supplies is connected with blower fan.
The present invention compared with prior art has the following advantages:
1, owing to is provided with annular tar oil treatment device among the present invention, by adopting gasification, thermal decomposition integrated, and utilize institute's aerogenesis body to cycle through the mode of catalytic pyrolysis layer, so that tar is decomposed into permanent gases, therefore, effectively reduce the content of tar in the biomass gasification process, realized once reinforced sustainable burning, without the purpose of tar emission.
2, because the present invention filters decoking process and finishes in same reacting furnace, therefore, not only greatly improve the utilization rate of biomass energy, and reduced energy consumption, also effectively improved combustion gas quality simultaneously.
