Description
Technical field：
Nitric oxide production method in industrial smoke is eliminated and reduced the present invention relates to one kind.
Background technology：
Gas denitrifying technology can be divided into two major class of dry and wet, the wherein selective catalytic reduction in Dry denitration at present
(SCR) and selective non-catalytic reduction (SNCR) technology be market most widely used (accounting for 80% denitrating flue gas market), technology most
Ripe denitration technology, its principle are the spray reducing agents such as ammonium hydroxide or urea into flue gas, direct at high temperature (or the association of catalyst
With under) with flue gas in NOx occur redox reaction, NOx is reduced into nitrogen and water.But the technology also has its very big office
Sex-limited, since chemical reaction needs to carry out at high temperature, and for medium small boiler and Industrial Boiler, exhaust gas temperature is remote
The required high temperature of chemical reaction cannot be reached, so, denitration effect is bad during low temperature.In addition, even if high-temperature boiler denitration is imitated
When fruit is good, the reducing agents such as substantial amounts of ammonia or urea are also consumed, by taking the 2500t/d line denitrations of 18, Chongqing as an example, to reality
The target of ten thousand tons of emission reduction NOx2 now, then must use SNCR denitration, if selection ammonium hydroxide (concentration 25%) is used as reducing agent, year
More than 60,000 tons of ammonium hydroxide, or 1.5 ten thousand tons of urea of consumption need to be consumed.And produce these ammonia or urea and consume 2.6 ten thousand tons of coal again and while produce
Raw many other pollutant (23.36 tons of COD, 9.3 tons of ammonia nitrogen, 0.047 ton of cyanide, 10.9 tons of SS, petroleum-types
1.56 tons, 0.031 ton of volatile phenol, 0.156 ton of sulfide, 150,000 tons of water), so again can produce some new pollutions at the same time.Ammonia
Water or urea are all the fertilizer for the increasing crop yield that people painstakingly fix and capture from air with consuming resource, now
But they are bred calamities for the future again to return to its owner in good conditions and becomes nitrogen again and be discharged into air, be the caving-in bash lost more than gain really.
The content of the invention：
The present invention discloses a kind of method that low-temperature denitration is realized using high-frequency impulse high voltage electric field, it is therefore an objective to：Do not make

Technical solution is：Allow the low-temperature flue gas with nitre more out of a large cylindrical container and the equipotential pipe of container
By the way that every tube center is provided with thorniness screw rod one longer than pipe and with pipe insulating, and screw rod upper end is with in sub
End is all fixed on two similar shelfs of size, and the shelf on top connects with supporting the porous plate of pipe to be fixed by high-tension porcelain insulator
Connect, or the shelf corner on top presses through the fixation suspention connection of wall porcelain insulator by insulator or height, and wall insulation porcelain is pressed through in height
The top of bottle is passed through high-frequency impulse high-voltage electricity.Thorniness screw rod is vacantly hanging in the center of pipe, the shelf of lower part；In the middle part of screw rod
Position, by every group of two nuts, grip the multiple claw type electrode slices of connection, claw type electrode slice is the stainless steel of multijaw
Piece, on every screw rod, is fixed with 20~200 claw type electrode slices and forms thorniness, or use commercially available prickle bar.
Under high-frequency impulse high-voltage electricity is drawn by the high top for pressing through wall porcelain insulator, make thorniness screw rod or prickle bar powered.
After energization, between claw type electrode slice on screw rod and the pipe for connecing power cathode, high-frequency impulse high voltage electric field will be formed, when
When band nitre (NOx, wherein NO account for more than 90%) flue gas is by the high voltage pulse electric field, the unstable NO in flue gas will be decomposed
For nomadic nitrogen and free oxygen, and then form N2 and O2, realize the purpose without using the consumptive material denitration such as ammonium hydroxide and urea.Experiment card
Bright, the present invention must use high-frequency impulse high voltage electric field just effective, if using direct current constant electric field, regardless of voltage levels or polarity
How, at all can not denitration, can only produce the effect of electrostatic precipitation.
The present invention declare patent on the same day and meanwhile declared two different utility model patents, title is respectively：" arteries and veins
Leap high piezoelectric field low-temperature denitration device " and " high voltage pulse electric field low-temperature denitration and cleaner ".
The claimed technical characteristic of the present invention is：In the body, cathode pipe frame plate and lower cathode tube are fixedly connected with
Frame plate, between upper cathode pipe frame plate and lower cathode pipe frame plate, is fixedly connected with cathode tube, in cathode tube hub, there is anode spiral shell
