2o, O
2equimolecular, produces the very high free radicals of oxidisability such as O, OH, by SO
2be oxidized into SO with NO
3and NO
2, then absorbed by water.The method is still in the industrial experiment sexual stage for various reasons.Wet method synchronized desulfuring and denitrifying technology can be divided into two classes according to the difference of NO principle of absorption: the one, by with absorbent complexing, as Fe-EDTA method; The 2nd, adopt Oxygen in Liquid agent to be oxidized.Just proposed Fe-EDTA method as far back as early seventies foreign scholar, but so far there are no, industrialization is reported.Therefore, people pay close attention to wet oxidation absorption desulfurizing and denitrifying process simultaneously more.It is first the NO of indissoluble to be oxidized to NO that wet oxidation absorbs desulfurizing and denitrifying process simultaneously
2etc. high state nitrogen, with SO
2be absorbed agent absorbs simultaneously.Wet oxidation absorption is broadly divided into chemical addition agent oxidation absorption and forced oxidation absorbs two classes.Chemical addition agent oxidation absorption technique is relatively more simple ripe.
Wet oxidation absorb simultaneously desulfurizing and denitrifying process oxidation with absorption integrated, investment cost is low, good economy performance, removal efficiency are high, compares with other technique, simply ripe, can be used in the transformation of original wet desulphurization device.

6, the waste gas after desulfurization and denitration is discharged from exhanst gas outlet 9.
In above-described denitrification process, sodium base absorbant is the remaining SO of NaOH Absorption Desulfurization reaction
2, absorption product is Na
2sO
3and water, Na
2sO
3with NO and NO
2there is redox reaction, generate Na
2sO
4and N
2, contribute to NOx to remove.In desulphurization reaction, 80～90% desulfurization degree can greatly reduce the spray number of plies and liquid-gas ratio, has good economy for spray section 11.
Because NO itself is water insoluble, so traditional wet desulphurization device does not possess denitration function substantially, in order to realize removing of NOx, NO must be oxidized to the NO of higher valence state
2, N
2o
3contour valence state nitrogen oxide, so the utility model adopts the oxidisability additives such as potassium permanganate, sodium chlorite, clorox.In addition in liquid phase NO oxidizing process, in order to improve oxidation assimilation effect, must improve the time of staying and the contact area of reaction, so in the utility model, by the design of packing layer 8, make packing material absorbing there is longer reaction time and gas-liquid contact surface than traditional spray absorber.If but adopt simple packing layer (not having spraying layer 3 to carry out desulfurization), SO
2and between NOx, exist competition to absorb, and affect the oxidation assimilation effect of NOx, consider that traditional calcium-based desulfurization easily stops up packing layer, so carried out the bicirculating filler spray of two-part composite design simultaneously.And spray section 11 described in the utility model adopts traditional calcium base spray desulfurization, packing section 13 adopts the sodium based filler oxidation of adding oxidant to absorb denitration, and absorbent circulates respectively, so adopt the filler of sodium base absorbant not have blockage problem.
Comparative example 1: in patent 201120575383.7 " a kind of while removes the device of sulfur dioxide and nitrogen oxide from flue gas/exhaust gas ", a kind of double-deck device of processing waste gas has been proposed, but compare with device of the present utility model, the structure of this patent is obviously complicated, need peripheral hardware denitration alkali lye preparation tank, desulfurization alkali lye preparation tank, denitration circulating tank and desulphurization circulating tank etc., and carrying out in the process of waste gas purification, also need constantly to pass into NO
2, to promote denitration.Corresponding, in the utility model, spray section 11 is carried out in the process of desulfurization, takes full advantage of spray section 11 and can not remove completely the SO in waste gas
2(only having 80～90% desulfurization degree), and again by denitrification process, carry out remaining SO
2further remove, recycling removes remaining SO
2after product promote denitration reaction; Make the waste gas purification carrying out in this way, not only solved in traditional exhaust-gas treatment problem SO
2and between NOx, exist competition to absorb, and then affect the hang-up of the oxidation assimilation effect of NOx, further, in the process of denitration, solve without carrying out extra material and added, can obtain the oxidizability that improves NOx, and then the hang-up of raising the efficiency, and the existence of the devices such as the outer absorbent circulating box 10 of absorbent EGR 5 and tower further makes the utility model reduce the dependence of device to external world, greatly degree carry out self-circulation mode operation.
Comparative example 2: in patent 201220564006.8 " a kind of gas cleaning plant ", another double-deck device of processing waste gas has been proposed, but compare with device of the present utility model, obviously complex structure, in the purification process of waste gas, arranges many places liquid barrier, and then make gas in mobile process, the constantly break-in due to barrier, and then increased the time that gas-liquid exchanges, promote the efficiency purifying; And it is corresponding, at the utility model, by the waste gas purification apparatus of multilayer, at at all levels, process different waste gas, and utilize fully the chemical characteristic of contained various pending materials in waste gas, promote the further purification of waste gas, make suitable simple of apparatus structure of the present utility model, and in multiple filling layers A and filler B, carry out gas-liquid exchange, not only can extend the time that gas passes through, further, can also increase the contact area between gas-liquid, further increase the efficiency of gas-liquid exchange.
