(1) technical field:

Air tubular plasma generator interstitial structure of the present invention is related to making the plasma generator of medium with air, belongs to Ion generates and spark gap class (H01T).

(2) background technique:

Existing untransferable arc plasma generator, substantially using inert gas as working media (carrier), material expensive, It is at high cost；Structural life-time is short；Hardly possible maintenance.People start to turn to using air as the developmental research of the plasma generator of medium.

A kind of 1 Chinese invention patent of documents<high power air plasma generator>(patent No. ZL022761748) A kind of<plasma generator that air is medium>is disclosed, although it is simple, easy to maintenance and at low cost to realize structure, from It is seen on electric arc moving structure, is still traditional untransferable arc structure, i.e., cathode is fixed on top, generates fixed arc；With regard to it is equal from For the service life of electronic generator, do not improve, greatest problem is that application range is limited, cannot be used for high-temperature process.

A kind of 2 Chinese invention patent of documents<inner-cooled anode low-power air plasma generator>(patent No. ZL2004200604268 a kind of<plasma generator that air is medium>) is also disclosed, structure is simple, ties up although also having Repair conveniently, it is at low cost, it is still traditional untransferable arc structure that the service life is long, but from electric arc moving structure, i.e. cathode is fixed on Side generates fixed arc；It is not complete air dielectric but air and inert gas are used in combination from the point of view of air dielectric, does not have Have real with full the air gap.So above structure is simple, easy to maintenance, at low cost, service life long feature is also limited, office Portion；Greatest problem is that application range is limited, and the processing occasion of the especially industrial dangerous waste of high temperature is not available.

So the air plasma generator that exploitation can handle hot industry hazardous waste is brought into schedule, and handle high temperature The key technology of air plasma generator first is that its interstitial structure.

(3) summary of the invention:

Air tubular plasma generator interstitial structure provided by the invention exactly solves to make medium and again reality with air The interstitial structure of the long-life plasma generator of existing hot industry hazardous waste processing, the interstitial structure are able to achieve air tubular Plasma generator master-plan is to multi-functional demands such as the water guide in gap, air guide, electric arc transmission, supports.

Technical solution is as follows:

Air tubular plasma generator interstitial structure, comprising: cathode, anode, gap, it is characterized in that:

1) cathode 1 is located at plasma generator axial direction middle section center, is cylindrical body, inside there is the yin mobile for electric arc Pole hollow pipe 1.1；It is also cylindrical body that anode 3, which is located at axial lower section center, is inside also had empty for the mobile anode of electric arc Heart pipeline 3.1；Cathode and anode axial direction junction are gap 2.2) gap location sets a compression ring cylinder 2.3, includes: 1. compression ring column External surface is provided with the jet annular groove 2.2 being connected to outside air gas handling system 7；2. compression ring cylinder centre bore 2.1 and cathode are empty Heart pipeline 1.1 is connected to anode hollow pipe 3.1；3. the oblique air guiding through hole of radial direction being evenly distributed in compression ring cylinder equipped with W item 2.4；4. setting the vertical water inlet pipe 6.4 in gap that W group is evenly distributed, the vertical water inlet pipe 6.4 in gap and air collector in compression ring cylinder The water-cooling system 6 of shape plasma generator is connected to.

Above-mentioned water-cooling system 6 and air induction system 7 are described in detail in specific embodiment below in conjunction with attached drawing.Above-mentioned water cooling The formation of cathode external spiral inlet channel 6.3 and anode external spiral inlet channel 6.5 and structure are in specific embodiment below in system Middle combination attached drawing is described in detail.Above-mentioned 3.1 section of anode hollow pipe can be the stairstepping amplified along export direction internal diameter.

The invention has the advantages that:

1) this air tubular plasma generator interstitial structure guarantees that gap is passed through air plasma completely, solves It is existing using inert gas material expensive, at high cost；The problems such as structural life-time is short, difficult maintenance.

2) cylindrical body cathode and anode construction are used, directly cooled barrel temperature is low, and cylindrical body discharge it is equal from Sub- arc temperature is up to 3000 degree or so, is able to satisfy industrial dangerous waste high-temperature process long-life demand.Since cathode is by existing The upper end that is fixed on generate electric arc (such as two middle term of documents 23, one middle term 5 of documents), becoming cathode is to be located at The cylindrical body of section center, barrel are the hollow pipe mobile for electric arc；Anode is the tubular for being located at lower end center Body, barrel are also the hollow pipe mobile for electric arc；Gap is in anode and cathode junction.I.e. electric arc 10 is moved in two cylindrical inner walls Dynamic, heating surface substantially increases.Cathode barrel electric arc is mobile, and arc root heat dispersion, electrode is not easy to be burned, anode arc moving cylinder Wall temperature is not high, and ejects electric arc 10A extreme temperatures.So the present invention is able to satisfy the industrial dangerous waste high-temperature process long-life Demand.

3) interstitial structure provided also has water guide, leads air, is fixed in addition to generating striking and separation cathode anode function The functions such as position, support, insulation；And water guide, air guide are structures independently, are independent of each other.See Fig. 1, Fig. 3, Fig. 6, gap location There is W root diameter to oblique air guide siphunculus 2.4 in compression ring cylinder 2.3, keeps air uniform from axial air slot 7.2, gap jet annular groove 2.2 After indentation, it is discharged into centre bore 2.1, sprays air to gap location electric arc.See Fig. 1, there is W group vertical gap vertically to intake in compression ring cylinder Pipe 6.4；Make the water inlet even drop down of the whereabouts of cathode external spiral sink 6.3 in it, and through the vertical water inlet pipe in uniform gap 6.4, anode external spiral sink 6.5 is discharged into lower annular return flume 6.6.See that Fig. 1, compression ring cylinder are set to axial tubular cathode and anode two End, to two ends positioning support.So the interstitial structure with compression ring cylinder not only generates striking and separation anode anode function Outside, also have that water guide, to lead air, positioning, support, insulation etc. multi-functional.And water guide, air guide are structures independently, mutually not It influences.And it is small in size, it occupies little space, meets the demand of the master-plan of tubular Structure of the cathode and the anode.

4) cooling effect optimizes: water-cooling system used in the embodiment of the present invention is returned from the vertical water inlet pipe in upper end, upper annular Sink enters the radial spiral inlet channel against cathode and inputs, downwards through the vertical water inlet pipe in gap, anode external spiral inlet channel, stream After entering lower annular return flume, then it is discharged back up through cyclic annular water outlet and outlet pipe.The downward cooling cathode of water inlet and anode, are returned Water cools down lower water-back water proof cylinder, gas-guide tube and shell etc. upwards.Two spiral inlet channels and to cool down heat-exchange surface twice very big, it is cooling Effect pole optimization.
