assembly 5，Then pass through the space that the pitch space of eddy flow screw thread 5-20 enters between the head end of the first electrode 5-5 and the rear end of the second electrode 5-1 in swirling eddy mode and constituted region of discharge，Entered in the plasma arc district 1-7 in gasification furnace 1 by the compression duct 5-26 at the second electrode 5-1 center again，When applying electric energy between the first electrode 5-5 and the three electrode 7-1，Region of discharge in the first discharge assembly 5 just forms high-temperature plasma electric arc，Simultaneously，Discharge between head end and the second electrode 5-1 of arc electrode 7-2，Form initial arc，Then solenoid 7-18 is reversely energized，Drive rod 7-19 is made to be moved rearwards by，Move after driving arc electrode 7-2，The head end making arc electrode 7-2 moves back to the 3rd electrode 7-1、Isolation duct 7-3 in，Thus electric arc is guided to the 3rd electrode 7-1 from the second electrode 5-1，Make generation high-temperature plasma electric arc between the second electrode 5-1 and the three electrode 7-1；nullAfter water vapour is carried out ionization activation by the region of discharge in the first discharge assembly 5 and decomposes，Mix with high-temperature plasma electric arc，The plasma arc district 1-7 in gasification furnace 1 is entered into by compressing duct 5-26，The high-temperature plasma electric arc again produced by plasma arc district 1-7 decomposes，It is broken down into hydrogen completely、The activity chemistry thing of oxygen，Then gasification zone 1-4 is entered as gasifying agent from the slag mouth 1-5 above plasma arc district 1-7，At this moment it is solid organic waste substances rubbish charcoal after pyrolysis at gasification zone 1-4，The hydrogen that water vapour decomposes、Oxygen activity chemicals carry out chemical reaction as gasifying agent and rubbish charcoal，Generate the hydrogen-rich synthetic gas being main component with carbon monoxide and hydrogen，The reaction carried out is exothermic reaction，Simultaneously，The heat of high-temperature plasma electric arc release rises to the 1-4 of gasification zone from slag mouth 1-5，Ash fusion is become the slag of liquid，The slag of liquid falls from slag mouth 1-5，Slag bath is fallen into by the slag notch 1-8 below plasma arc district 1-7 and water seal 6；nullThe waste heat of high-temperature plasma electric arc runs up in gasification furnace with the reaction heat of generation in the 1-4 of gasification zone，Heat needed for raw material stoving and pyrolysis is provided，The gasification zone 1-4 upper area in gasification furnace is made to constitute pyrolysis zone，The upper area of pyrolysis zone constitutes baking zone，The water vapour produced in raw material stoving and pyrolytic process、Coal smoke and gaseous state tar carry out ascending motion with thermal current，Enter into loop back in trachea 16 by the QI KOU 1-10 that recycles of the furnace roof that gasifies，The inner side wall body of cooler 13 and the outside wall body looping back trachea 16 between cooling jacket 13-2 absorption cycle muffler 16 in the heat of gas，The gas looping back in trachea 16 is made to lower the temperature and density increase，According to gravity circulation principle，After looping back the gas cooling in trachea 16，Carry out descending motion，The gasification zone returning to gasification furnace bottom by looping back QI KOU 1-9 carries out second gasification，Reach gasification completely；Solid organic waste substances enters into after in gasification furnace and runs from top to bottom according to its deadweight, moisture is baked out at baking zone, pyrolysis is carried out subsequently into pyrolysis zone, fixed carbon is become after effusion volatile matter, fixed carbon entrance gasification zone 1-4 and the hydrogen of water vapour decomposition, oxygen activity chemicals carry out the chemical reaction of exothermal nature, generate hydrogen-rich synthetic gas；The hydrogen-rich synthetic gas generated in gasification furnace is brought out by synthesis gas delivery outlet 1-2, utilizes as the unstripped gas producing methanol or dimethyl ether after cooling and purified treatment.
