Description
Technical field
This utility model relates to the denitrification apparatus that a kind of wet oxidation absorbs, and it belongs to a kind of equipment that oxynitride in flue gas is removed.
Background technology
Along with China's expanding economy, the environmental pollution brought in energy-consuming is also increasingly severe.Wherein, the destruction of atmospheric aerosol, acid rain, greenhouse effect and ozone layer has become four big killers of harm people's existence.The harmful substances such as flue dust contained by coal-fired flue-gas, sulfur dioxide, nitrogen oxides are the main contributors causing atmospheric pollution, acid rain and greenhouse effect.In China, the harmful substance such as sulfur dioxide, nitrogen oxides is mainly produced by coal-fired process.
At present, the dry type denitration that flue gas adopts purifies technique, and the overwhelming majority is selective catalytic reduction (SCR), and only minority device adopts SNCR method (SNCR).SCR technique denitration rate is high, but investment cost is relatively big, and operating cost is high, although and SNCR technique investment cost is less, but denitration efficiency is low, wayward.
Summary of the invention
The purpose of this utility model is to solve existing denitration to purify the technical problem that investment cost is big, operating cost is high and denitration efficiency is low existed, it is provided that the high-speed rotary flow pattern desulfurizer that a kind of denitration efficiency is high, investment cost is little and operating cost is low.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
The denitrification apparatus that a kind of wet oxidation absorbs, it includes absorption tower, wherein: it also includes oxidation system, described oxidation system is by oxidation reactor, oxygen station, ozonator, pneumatic homogenizer and two ejector compositions, pneumatic homogenizer is located in the inner chamber of oxidation reactor and the inner chamber of oxidation reactor is separated into two oxidizing chambers, first ejector is located in the first oxidizing chamber and the air inlet of first ejector is connected with the gas outlet of oxygen station by pipeline, second ejector is located in the second oxidizing chamber and the air inlet of second ejector is connected with the gas outlet of ozonator by pipeline, the exhanst gas outlet of oxidation reactor is connected with the gas approach on absorption tower.
Owing to this utility model have employed technique scheme, first the NO in flue gas is oxidized to NO2(, based on NO, NO is water insoluble for the NOx in flue gas, NO2It is dissolved in water), enter back into absorption tower and absorbed by aqueous slkali.Because denitration and desulfurization carry out in same absorption tower, same absorbent is adopted to carry out removing (absorbent can use Caustic soda, soda, Calx and ammonia) so also known as double; two de-technology, solving the technical problem that investment cost is big, operating cost is high and denitration efficiency is low that existing denitrification apparatus exists.Therefore, compared with background technology, this utility model has denitration efficiency height, investment cost is little and operating cost is low.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in drawings, the denitrification apparatus that a kind of wet oxidation in the present embodiment absorbs, it includes absorption tower 4, wherein: it also includes oxidation system, described oxidation system is by oxidation reactor 1, oxygen station 2, ozonator 3, pneumatic homogenizer 5 and two ejectors 6, 7 compositions, pneumatic homogenizer 5 is located in the inner chamber of oxidation reactor 1 and the inner chamber of oxidation reactor 1 is separated into two oxidizing chambers, first ejector 6 is located in the first oxidizing chamber and the air inlet of first ejector 6 is connected with the gas outlet of oxygen station 2 by pipeline, second ejector 7 is located in the second oxidizing chamber and the air inlet of second ejector 7 is connected with the gas outlet of ozonator 3 by pipeline, the exhanst gas outlet of oxidation reactor 1 is connected with the gas approach on absorption tower 4.
Operation principle of the present utility model is: flue gas enters oxidation reactor 1 makes NO be oxidized to NO by oxidation3.Oxidation reactor principle is: flue gas enter oxidation reactor first with the oxygen mix of spirt, mix further then through pneumatic homogenizer 5, contacting with the ozone mixing sprayed into and reach the oxidation to NO, enter absorption tower through snperoxiaized flue gas, absorption tower is spray column, spray column is divided into three layers, and from bottom, ground floor is spraying layer, the second layer is pallet, third layer is spraying layer, it is therefore an objective in order to improve mass tranfer coefficient；By being fully contacted with aqueous slkali, make SO2、NO2It is dissolved in aqueous slkali, thus reaching the purpose of purifying smoke.If absorbent is calcium alkali forms calcium sulfate and calcium nitrate, desulfurization up to more than 95%, denitration 80%.
