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, is industrially applied to plasma ignition, plasma spraying, metal smelt, heating plasma manufacture nano material, cutting, waste incineration and refuse process etc.In recent years, utilize the technical development of the dangerous harmful discarded object of plasma treatment and house refuse very fast, processing mode and the general burning mode of plasma are made a world of difference, plasma is a kind of state formed under ionosphere or electric discharge phenomena, will generate excited atom, excite molecule, reaction that the chemicals of the activity chemistry thing of dissociation atom, free atomic group, atom or molecular ion group and they and other collide and cause along with electric discharge phenomena.In plasma generator, discharge process makes work gas molecule lose outer-shell electron and form ionic condition, produces high temperature through mutually colliding, and temperature can reach more than several ten thousand degree.
Current, the gasifying agent used in conventional coal gasification apparatus is water vapour+air or water vapour+oxygen, when gasification furnace works, directly water vapour+air or water vapour+oxygen are sent into gasification furnace, water vapour and charcoal generation gas making are reacted and generates synthesis gas, its reaction is the endothermic reaction, need to provide heat by air or oxygen and charcoal generation oxidation reaction for it, the rate of gasification of this gasification mode is only about 70%, this will increase coal resources consumption, simultaneously, a large amount of CO 2 waste gas is produced in synthesis gas, not only have influence on the quality of synthesis gas, and discharge a large amount of greenhouse gas during rear class is produced.Spray into again in gasification furnace after steam heating being decomposed as utilized plasma torch and carry out chemical reaction with coke, the reaction occurred is exothermic reaction, the heat can supplied raw materials needed for oven dry and pyrolysis for gasification furnace, thus make gasification furnace not need input air or oxygen, in the synthesis gas produced, the fraction scale of hydrogen is high, and the content of waste gas is low.
House refuse due to calorific value low, fixed carbon content in chemical composition is few, as the water vapour by routine, air or oxygen carry out gasify household garbage as gasifying agent, it is the endothermic reaction that water vapour and charcoal react what generate that synthesis gas carries out, and will consume the heat of gasification furnace, gasification furnace needs input air or oxygen, and consume fuel, make waste gas content in synthesis gas high, in the synthesis gas obtained, useful component is quite low, is almost waste gas.Utilize plasma torch gasifying agent steam heating, water-molecule dissociation is made to be hydrogen, the activity chemistry thing of oxygen sprays into gasification furnace, chemical reaction is carried out with rubbish charcoal, what carried out is exothermic reaction, the heat can supplied raw materials needed for oven dry and pyrolysis for gasification furnace, thus 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 process house refuse, junk is converted into the industrial chemicals of human needs simultaneously.Therefore, as the synthesis gas of domestic garbage gasification become useful material, should preferably plasma heating decomposition water steam as the gasification technology of gasifying agent.
Plasma pyrolysis water hydrogen producing technology is one of water hydrogen manufacturing candidate technologies put forward recent years, because water is a kind of material of quite stable, in atmospheric conditions, temperature hydrone when 2000K decomposes hardly, the water of 25% is had to decompose during 2500K, during 3400 ~ 3500K, the molar fraction of hydrogen and oxygen reaches maximum, be respectively 18% and 6%, when 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 then can accomplish.
Although plasma technique in Disposal of Domestic field, the application prospect of coal gasification field and hydrogen preparation field is fine, but the arc torch of current plasma torch is outside nozzle, the zone of action of torch is external at rifle, as being used for heat resolve hydrone, there is the shortcoming that the efficiency of heating surface is not high, water-molecule dissociation rate is low.
Summary of the invention
The object of the invention is the shortcoming that efficiency is not high and water-molecule dissociation rate is low that will overcome the existence of existing plasma torch, manufacture and design a kind of efficiency of heating surface that can improve hydrone and the interior arc plasma gun improving water-molecule dissociation rate, for coal gasification apparatus, rubbish biomass gasification device or pyrolysis water device for producing hydrogen, after popularization and application, can overcome and directly use water vapour low as the rate of gasification existing for gasifying agent, coal resources consumption is large, the shortcoming that the greenhouse gas of discharge synthesis gas quality that is many and that produce is not high, to reduce coal resources consumption and GHG emissions mitigation.
