Abstract
The invention relates to a low-temperature plasma waste gas treatment pipe. The low-temperature plasma waste gas treatment pipe comprises a stainless steel pipe and maces, wherein sharp teeth are fully distributed on the maces; two ends of each mace both extend to form galvanized pipes; each mace and the galvanized pipe arranged on the mace penetrate through the axis of the stainless steel pipe in a suspending manner, wherein part of the galvanized pipe is exposed out of the stainless steel pipe; the maces and the stainless steel pipe are respectively connected to positive and negative electrode of high-voltage electricity. Compared with the prior art, the low-temperature plasma waste gas treatment pipe has the advantages that the maces and the stainless steel pipe are respectively connected with the positive and negative electrode of the high-voltage electricity; under the acceleration effect of an electric field, high-energy electrons are generated in the stainless steel pipe; when the average energy of the electrons exceeds the molecule chemical bond energy of a target management object, the molecule bond cracks so as to achieve the aim of eliminating gaseous pollutants; by multi-stage processing, pollutant molecules can be easily decomposed efficiently; the processing energy consumption is low; the secondary pollution is avoided.
Description
Technical field
The present invention 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, in the time that 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 general principle that adopts lower temperature plasma technology to carry out waste gas purification is: 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, 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, at present this technology is not yet ripe, 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.
Summary of the invention
The present invention 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.
Technical scheme of the present invention is achieved in that
A kind of 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, in the time that high energy electron average energy exceedes 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.
Adopt the invention has the beneficial effects as follows of technique scheme:
A kind ofly can avoid secondary pollution and the low a kind of low-temperature plasma exhaust-gas treatment pipe of cost.In the present invention, 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, produce ozone and water, finally produce carbon dioxide and water; Specifically, 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.Wherein the low life-span of galvanized pipe cost is long.
