Description
Technical field
This utility model is related to environmental technology field and in particular to a kind of oxidation-absorption high gravity desulfurization denitrating system.
Background technology
State Council continuously issues three files with regard to energy-saving and emission-reduction problem within 2013：《Ten measures of prevention and control of air pollution》、《State
Business institute is with regard to accelerating development the suggestion of energy-conserving and environment-protective industry》With《Prevention and control of air pollution action plan》, dirty to energy-saving and emission-reduction, air
Dye control proposes requirements at the higher level.
Process nitrogen oxides both at home and abroad at present and/or the method for sulfide mainly has：SNCR method
(SNCR), selective catalytic reduction (SCR), high energy electron active oxidation method, solution absorption method, oxidative absorption method, biology at
Logos etc..Non-selective catalytic reduction（SNCR method）And selective catalytic reduction（SCR method）It is mainly used to process nitrogen oxidation
Thing.
SNCR method is that handle contains NHxAfter the reducing agent of base sprays into the region that fire box temperature is 850～1100 DEG C, heat point rapidly
Solution becomes NH3 and other by-product, subsequent NH3With the NO in flue gasxCarry out SNCR reaction and generate N2, the method is less efficient,
Between 40-50%, advantage be invest relatively few；SCR method is in the presence of catalyst, using reducing agent（As NH3, liquefied ammonia, urine
Element）Come " selectivity " with flue gas in NOxReact and generate the N of nontoxic pollution-free2And H2O, its efficiency is higher than SNCR method,
80% about, but the catalyst costs of SCR method typically constitute the 40% about of SCR system initial outlay, and its operating cost is very big
Affected by catalyst life in degree, thus investment is higher.SNCR method and SCR method all must by the use of ammonia as reducing agent, and
Denitration enterprise often build the remote place of comparison in mostly, purchases, transports and preserves liquefied ammonia or the expense of carbamide is high, also has
Larger danger.
High energy electron active oxidation method is different according to the producing method of high energy electron, is divided into electron beam irradiation method again（EBA）
With impulse electric corona plasma method（PPCP）.Electron beam irradiation method（EBA）It is a kind of desulphurization denitration new technology, advantage is dry method
Processing procedure, does not produce waste water and dregs；Simple system, easy to operate, process is easily controllable；For different sulfur content flue gas and
The well adapting to property of change of exhaust gas volumn and Steam Generator in Load Follow；Side-product is ammonium sulfate and ammonium nitrate mixture, can be used as
Fertile.The Chengdu steam power plant of China introduced this electron beam irradiation technology in 1997, and actual motion desulfurization degree reaches more than 80%, but
Denitration efficiency is less than 20% it is seen that electron beam irradiation method is as wanted widespread adoption still to have a lot of work will do in industrially desulfurized denitration.
Impulse electric corona plasma method grows up on the basis of electron beam irradiation method, and its advantage is high energy electron
Produced by corona discharge itself, from without expensive electron gun, be also not required to radiation shield；Finished product can be used as fertilizer, does not produce
Raw secondary pollution；Within Ultra-short pulse action time, electronics obtains acceleration, and the ion big to the inertia not producing free radical
Do not accelerate, thus the method has very big potentiality in terms of energy-conservation；It does not also affect on the safe operation of station boiler.But
It is that the power consumption of this technology is higher, account for the 3-5% of power plant's gross generation.In addition high-power, the narrow arteries and veins of this high-voltage pulse power source
Punching, long-life how to realize etc. key problem have to be solved.
It is the characteristic of sour gas that solution absorption method utilizes nitrogen oxides and sulfide, by alkaline solution in waste gas
Nitrogen oxides and sulfide are removed, and can remove SO under certain condition simultaneously2And NOx.The advantage of the method is to reach
To SO2And NOxPreferably removal effect；Shortcoming be the specific denitrating system being adopted often exist catalyst surface fouling and in
The phenomenon of poison[1], cause obstruction and the corrosion of air preheater/gas heat exchanger.Further, since the NO in nitrogen oxides be difficult by
Solution absorbs, and also needs with reference to methods such as oxidation and complexations to NO process, technical process is relatively complicated.
Oxidative absorption method is frequently with ozone, H2O2、NaClO2Deng oxidant to SO2And NOxCarry out oxidation removal.The method is gone
Except efficiency is higher, and can desulfurization simultaneously it is easy to operation, but the ozone being adopted and NaClO are expensive, cause its desulfurization simultaneously
The high cost of denitration.Although H2O2Cheap, but H when reaction temperature reaches more than 60 DEG C2O2Start acutely to decompose, because
This, it is necessary to carry out cooling process to flue gas under conditions of industrial high temperature flue gas produces, investment cost is higher, is unfavorable for
Industrialization[2].
Biological treatment is dry method, the semi-dry process flue gas desulphurization denitration technology developing in recent years, but due to these skills
Art is still in laboratory development, and its desulphurization denitration mechanism waits to study, thus does not also possess the ability of practical application.
In sum, all there are the pluses and minuses of its own in various process nitrogen oxides, the method for sulfide, single method
With can not meeting reality need, thus joint removing sulfuldioxide is increasingly becoming countries in the world research institution, focus of attention
Focus.The development of this kind of technology is trend of the times, but how de- technology really ripe so far be actually rare.
