In order to address the above problem, now propose a kind ofly can avoid secondary pollution and the low low temperature plasma waste gas cleaning device of cost.
Utility model content
The utility model has overcome above-mentioned the deficiencies in the prior art, has proposed a kind ofly can avoid secondary pollution and the low low temperature plasma waste gas cleaning device of cost.
The technical solution of the utility model is achieved in that
A kind of low temperature plasma waste gas cleaning device, comprise: the stainless steel steelframe that two sides is parallel and symmetrical and be arranged on the parallel and symmetrical two sides stainless-steel sheet between the stainless steel steelframe of two sides, parallel between stainless steel steelframe and stainless-steel sheet, stainless steel steelframe comprises steelframe frame and is arranged on many stainless steel steel bars in steelframe frame; On the stainless-steel sheet of two sides, be vertically penetrated with the many stainless-steel pipes that are parallel to each other, in every stainless-steel pipe, be installed with a mace that is covered with pointed tooth, stainless-steel pipe and mace are all the direction of travel settings along air-flow, and mace does not contact with the inwall of stainless-steel pipe and both connect respectively the both positive and negative polarity of high-tension electricity; All extend at the two ends of described mace galvanized pipe, a part for galvanized pipe is exposed outside stainless-steel pipe, galvanized pipe the exposed termination in stainless-steel pipe outside be fixedly connected on and on stainless steel steel bar, make mace and be arranged on the unsettled axis through stainless-steel pipe of galvanized pipe on mace; Between steelframe frame and stainless-steel sheet, be connected and fixed by ceramic insulator.Between mace and stainless-steel pipe, do not contact to provide arcing distance; Described mace connects anodal, stainless-steel pipe connects negative pole, mace is realized point discharge, in stainless-steel pipe, produce electric field and produce corona phenomenon, under the acceleration of electric field, produce high energy electron, in the time that high energy electron average energy exceedes target improvement thing molecular chemistry bond energy, molecular scission, reaches the object of eliminating gaseous contaminant.
Concrete purification process is: waste gas enters in stainless-steel pipe, high energy electron, free radical isoreactivity particle and waste gas generation effect in low temperature plasma in pipe, molecule in waste gas is decomposed within the extremely short time, produce ozone and water, finally produce carbon dioxide and water.
As preferably, the contact portion of stainless-steel pipe and stainless-steel sheet is fixed by welding manner.Make like this stainless-steel pipe on stainless-steel sheet, be difficult for sliding.
As preferably, described galvanized pipe is bolted to connection on stainless steel steel bar.
As preferably, the two ends of described ceramic insulator are all bolted on stainless steel steelframe and stainless-steel sheet.
Adopt the beneficial effects of the utility model of technique scheme to be:
A kind ofly can avoid secondary pollution and the low low temperature plasma waste gas cleaning device of cost.Waste gas enters in stainless-steel pipe, and high energy electron, free radical isoreactivity particle and waste gas generation effect in the low temperature plasma in pipe are decomposed the molecule in waste gas within the extremely short time, produces ozone and water, finally produces carbon dioxide and water; Low-temperature plasma degradation pollutant general principle is under the acceleration of electric field, produce high energy electron, in the time that electronics average energy exceedes target improvement thing molecular chemistry bond energy, molecular scission, reach the object of eliminating gaseous contaminant, this technology is easy to make the efficient decomposition of contaminant molecule and processes energy consumption low.
