For central electrode in the reactor in prior art equipment, when processing high humidity gas, often strike sparks, flashover or arc phenomenon, cause and cause that insulating support is by calcination, cause the performance reduction, the problem such as shorten useful life.For this reason, the utility model is a kind of insulating sleeve that increases the suspension central electrode of creepage distance that increased the creepage distance special design.
The utility model purpose is: on the technical foundation of existing insulating support, innovative design a kind of adaptation under 100% saturated steam environment, can increase the insulating sleeve of insulating support creepage distance again for what hang central electrode.
For achieving the above object, design of the present utility model is:
On the technical foundation at existing triangle insulating support, design a kind of can be directly and the matching used insulating sleeve of insulating support, to extend the creepage distance of insulating support and pipe external electrode.For insulating part on central electrode is not caused under the prerequisite of sparking with the reactor negative pole, innovative design a kind of insulating sleeve that increases the dish-shaped combining structure of creepage distance.
According to above-mentioned design, the technical scheme that the utility model adopts is:
A kind of insulating sleeve that increases the suspension central electrode of creepage distance, by electrode centers bar, insulating sleeve and insulating support, formed, its insulating sleeve is inserted in the central ring of insulating support, is threaded connection and forms the integral type insulation assembly consisted of insulating sleeve, it is characterized in that:
A, wherein, described insulating sleeve is divided into again two kinds of stiff end sleeve pipe and terminals sleeve pipes;
B, the whole insulating material of the polytetrafluoroethylene of high strength toughness that adopts of described insulating sleeve are made.
Above-mentioned stiff end sleeve pipe is the butterfly insulating part of opening blind screw hole of the threaded interface of end, and its casing length is 60mm, and its butterfly length is 40mm.
The butterfly insulating part of opening hole that the thin outer end, the inner that above-mentioned terminals sleeve pipe is the Intermediate Gray hickey is thick, its sleeve pipe total length is 110mm, and inner butterfly length is 50mm, and outer end butterfly length is 40mm; And the butterfly creepage distance at inside and outside two ends equates.
The butterfly creepage distance of above-mentioned stiff end sleeve pipe equates with the butterfly creepage distance of terminals sleeve pipe the inner and outer end, within its butterfly creepage distance is set in 200～210mm scope.
Above-mentioned electrode centers bar is that the externally threaded Metallic rod of being with that equals stiff end sleeve pipe blind screw hole length is offered at two ends.
The utility model is by hanging electrode centers bar two ends to be fixed in the insulating sleeve of terminals and stiff end, after by matching used mutually insulating support card support in opposite directions on it the rolling in the muscle groove of pipe external electrode, can form a unitary reactor with insulating sleeve suspension strut central electrode.
The utility model compared with prior art, has following apparent substantive distinguishing features and advantage:
1, the utility model has overcome insulating support can only adapt to the shortcoming of using under the light concentration gas environment, it not only can the suspension strut central electrode, can also increase creepage distance, 2.5～3 times have been increased than general insulating support creepage distance, can thoroughly prevent from contacting steam and cause sparking, greatly improve the purification efficiency of reactor, also improved the useful life of equipment.
2, the insulating support of the insulating sleeve of this Patent design and common creepage distance forms the insulation assembly of isolation positive and negative electrode in the lump, and it can be used as general part and insulating support supports the use, and has saved the cost of development of new insulating support.
3, especially the design of the blind screw hole of stiff end sleeve pipe reduces casing length, has simplified the connected mode of electrode centers bar, has reduced the cost of manufacturing of making central electrode.
The beneficial effects of the utility model are: the product structure of this Patent design is simple, applied widely, practical, has extensive promotional value.
