Description
Technical field
The present invention relates to electric heating equipment, particularly relate to a kind of plasma heating equipment.
Background technology
Current, plasma technology is widely used, and the industrial plasma ignition, plasma spraying, metal smelt, heating plasma of being applied to manufactured nano material, cutting, waste incineration and refuse processing etc. In recent years, utilize the technical development of the dangerous harmful discarded object of Cement Composite Treated by Plasma and house refuse very fast, the processing mode of plasma and general burning mode are made a world of difference, plasma is a kind of state forming under ionosphere or electric discharge phenomena, is accompanied by that electric discharge phenomena will generate excited atom, excite molecule, dissociation atom, free atomic group, atom or molecular ion group's activity chemistry thing and they collide with other chemicals and reacting of causing. In plasma generator, discharge process makes work gas molecule lose outer-shell electron and forms ionic condition, produces high temperature, more than temperature can reach several ten thousand degree through mutually colliding.
Current, the gasifying agent using in conventional coal gasification apparatus is water vapour+air or water vapour+oxygen, in the time that gasification furnace is worked, directly water vapour+air or water vapour+oxygen are sent into gasification furnace, water vapour is reacted with charcoal generation gas making and generate synthesis gas, its reaction is the endothermic reaction, need to provide heat for it by air or oxygen and charcoal generation oxidation reaction, the rate of gasification of this gasification mode is only 70% left and right, this will increase coal resources consumption, simultaneously, in synthesis gas, produce a large amount of CO 2 waste gas, not only have influence on the quality of synthesis gas, and make to discharge a large amount of greenhouse gases in rear class production. as spray into again in gasification furnace and carry out chemical reaction with coke after utilizing plasma torch that steam heating is decomposed, the reaction occurring is exothermic reaction, can supply raw materials and dry and the required heat of pyrolysis for gasification furnace, thereby make gasification furnace not need input air or oxygen, in the synthesis gas of producing, the fraction scale of hydrogen is high, and the content of waste gas is low.
House refuse is because calorific value is low, fixed carbon content in chemical composition is few, as the water vapour with conventional, air or oxygen carry out gasify household garbage as gasifying agent, water vapour reacts what generate that synthesis gas carries out with charcoal be the endothermic reaction, will consume the heat of gasification furnace, and gasification furnace needs input air or oxygen, and consume fuel, make in synthesis gas waste gas content high, in the synthesis gas obtaining, useful component is quite low, is almost waste gas. utilize plasma torch gasifying agent steam heating, make hydrone be decomposed into hydrogen, the activity chemistry thing of oxygen sprays into gasification furnace, carry out chemical reaction with rubbish charcoal, what carry out is exothermic reaction, can supply raw materials and dry and the required heat of pyrolysis for gasification furnace, thereby make gasification furnace not need input air or oxygen, the synthesis gas quality better that house refuse is transformed, reach the requirement of industrial chemicals, synthesis gas is again by rear class device fabrication methyl alcohol or dimethyl ether product, realize pollution-free processing house refuse, junk is converted into human needs's industrial chemicals simultaneously. therefore,, as the synthesis gas of domestic garbage gasification become to useful material, preferably plasma heating decomposition water steam is as the gasification technology of gasifying agent.
Plasma pyrolysis water hydrogen producing technology is one of water hydrogen manufacturing candidate technologies putting forward recent years, because water is a kind of material of quite stable, under condition of normal pressure, temperature hydrone in the time of 2000K decomposes hardly, when 2500K, there is 25% water to decompose, when 3400～3500K, the molar fraction of hydrogen and oxygen reaches maximum, be respectively 18% and 6%, in the time that temperature reaches 4200K, hydrone will all be decomposed into hydrogen, hydrogen, oxygen, oxygen and hydrogen-oxygen atomic group, general mode of heating is difficult to reach so high temperature, uses plasma torch can accomplish.
Although plasma technique is fine in the application prospect of Disposal of Domestic field, coal gasification field and hydrogen preparation field, but the arc torch of current plasma torch is outside nozzle, the zone of action of torch is external at rifle, heat decomposition water molecule as being used for, have the shortcoming that the efficiency of heating surface is not high, hydrone resolution ratio is low.
Summary of the invention
The object of the invention is to overcome the not high and low shortcoming of hydrone resolution ratio of efficiency that existing plasma torch exists, manufacture and design a kind of interior arc plasma gun that can improve the efficiency of heating surface of hydrone and improve hydrone resolution ratio, for coal gasification apparatus, rubbish biomass gasification device or pyrolysis water device for producing hydrogen, after popularization and application, can overcome direct use water vapour low as the existing rate of gasification of gasifying agent, coal resources consumption is large, many and the not high shortcoming of synthesis gas quality of producing of the greenhouse gases of discharge, to reduce coal resources consumption and GHG emissions mitigation.
