Description
Technical field
The utility model relates to waste gas purification apparatus technical field, particularly a kind of low-temperature plasma exhaust-gas treatment pipe.
Background technology
Along with the development of industrial economy, the volatility waste gas that the industries such as chemical industry, oil and coating produce is increasing, and these waste gas have not only brought serious pollution to environment, also the health of human body have been produced to great harm.Process now these waste gas, conventionally adopt combustion method, oxidizing process etc., but these methods all exist expense higher and easily cause the defects such as secondary pollution.At present, lower temperature plasma technology is remarkable aspect gaseous contaminant improvement, low temperature plasma be continue solid-state, liquid, material the 4th state after gaseous state, when applied voltage reaches the discharge voltage of gas, gas is just breakdown, generation comprises electronics, various ions, atom and free radical are at interior mixture, although electron temperature is very high in discharge process, but heavy particle temperature is very low, whole system presents low-temperature condition, so be called low temperature plasma, the basic principle that adopts lower temperature plasma technology to carry out waste gas purification is: under the acceleration of electric field, produce high energy electron, when high energy electron average energy surpasses target improvement thing molecular chemistry bond energy, molecular scission, reach the object of eliminating gaseous contaminant, this technology is easy to make contaminant molecule efficiently to decompose, it has become current research forward position.But because plasma is a cross discipline comprising on the basic subjects such as discharge physics, discharge chemistry, Chemical Reaction Engineering, electronic technology and material science, therefore, this technology is not yet ripe at present, and the cost of at present a lot of low temperature plasma waste gas cleaning devices is high and still can produce secondary pollution.
In order to address the above problem, now propose a kind ofly can avoid secondary pollution and the low a kind of low-temperature plasma exhaust-gas treatment pipe 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 exhaust-gas treatment pipe of cost.
The technical solution of the utility model is achieved in that
A low-temperature plasma exhaust-gas treatment pipe, comprising: stainless-steel pipe and the mace that is covered with pointed tooth; All extend at the two ends of mace galvanized pipe, every mace and be arranged on the unsettled axis through stainless-steel pipe of galvanized pipe on mace, and wherein a part for galvanized pipe is exposed outside stainless-steel pipe; Mace and stainless-steel pipe are connected respectively the both positive and negative polarity of high-tension electricity.Between mace and stainless-steel pipe, do not contact to provide arcing distance; 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, when high energy electron average energy surpasses target improvement thing molecular chemistry bond energy, molecular scission decomposes the molecule in waste gas within the extremely short time, reaches the object of eliminating gaseous contaminant.
As preferably, stainless-steel pipe and mace are all the direction of travel settings along air-flow.Make like this waste gas fully enter in stainless-steel pipe.
Adopted the beneficial effects of the utility model of technique scheme to be:
A kind ofly can avoid secondary pollution and the low a kind of low-temperature plasma exhaust-gas treatment pipe of cost.In the utility model, waste gas enters in stainless-steel pipe, and the high energy electron in the low temperature plasma in pipe, free radical isoreactivity particle and waste gas generation effect are decomposed the molecule in waste gas within the extremely short time, produce ozone and water, finally produce carbon dioxide and water; Specifically, low-temperature plasma degradation pollutant basic principle is under the acceleration of electric field, produce high energy electron, when electronics average energy surpasses 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.Wherein the low life-span of galvanized pipe cost is long.

The specific embodiment
The specific embodiment of the present utility model is as follows:
Embodiment: a kind of low-temperature plasma exhaust-gas treatment pipe, as Figure 1-3, comprises stainless-steel pipe 1 and the mace 2 that is covered with pointed tooth; All extend at the two ends of mace 2 galvanized pipe 3, every mace 2 and be arranged on the unsettled axis through stainless-steel pipe 1 of galvanized pipe 3 on mace 2, mace 2 is 4.5cm with the distance of stainless-steel pipe 1 inside pipe wall, and wherein a part for galvanized pipe 3 is exposed outside stainless-steel pipe 1; Mace 2 and stainless-steel pipe 1 are connected respectively the both positive and negative polarity of high-tension electricity; Stainless-steel pipe 1 is all the direction of travel settings along air-flow with mace 2.
As shown in Fig. 4-5, the vertical stainless-steel sheet 4 through two sides Parallel Symmetric of stainless-steel pipe 1, in the outside of two sides stainless-steel sheet 4, be provided with the stainless steel steelframe 5 of two sides Parallel Symmetric, stainless steel steelframe 5 comprise steelframe frame 6 and the steelframe frame 6 that arranges in many stainless steel steel bars 7; 3 exposed terminations in stainless-steel pipe 1 outside of galvanized pipe are fixedly connected on and on stainless steel steel bar 7, make mace 2 and be arranged on the unsettled axis through stainless-steel pipe 1 of galvanized pipe 3 on mace 2; Between steelframe frame 6 and stainless-steel sheet 4, by ceramic insulator 8, be connected and fixed.
