Operation principle: electric cabinet 28 controls each water pump and valve, from cremator 27 flue gas out after secondary combustion chamber burning, remove the most of dioxin in flue gas, then temperature can reach the flue gas of more than 1000 DEG C through heat exchanger chilling, make its temperature below 250 DEG C, in desulfurized dust collection column, flue gas increases downward flow velocity after Venturi tube 10, flue gas is directly blown into bottom tower body in the water that amasss, flue gas is after washing, upwards overflow from water again, upwards enter ball milling layer through water conservancy diversion flaggy, the course of work of this ball milling layer is the mode of operation of adjustable dynamically many times of venturi, in the mode that dynamic rotary ball milling is variable, rotate while cremator runs change, self-excitation, ball milling synchronously changes, explain to be exactly the little venturi of existing several ten thousand static state is become a hundreds of thousands dynamic venturi principle by conventional principles, increase liquid gas contact area and mass-transfer efficiency to greatest extent, when dynamic motion, ball milling circular motion is done under ascending air impact and reverse liquid spray make inner-tower filling material ball be half suspended state, make the corresponding reduction of wind speed resistance, reach desulfurization and dedusting effect, solve equipment scaling, the problems such as blocking, desulfuration efficiency can reach more than 95%, efficiency of dust collection more than 99%, adapt to dynamic range more than 45%, system all technical is reached advanced world standards, floor space is little, operating cost is low, accommodation can comprise any desulfurizing agent within the scope of current WFGD and use, and also adapts to various single udst separation, organic exhaust gas biodegradation purification and purifying and recovering system simultaneously.Solve in prior art a series of difficult problems having a strong impact on mass transfer rate simultaneously, make it to have: solve the gas of conventional dead vulcanization bed filler, liquid contact surface is little, a difficult problem for turbulent bed stuffing operation instability; Absorbing liquid is fully used and consumption reduces, and to the pressure of absorbing liquid and degree of atomization without strict demand, reduces operating cost; Low-resistance, efficiently mass transfer effect can be reached without the need to increasing blast in addition; The absorbing liquid circulatory system of more than double loop can be realized, reach multi-stage diffluence and liquid phase multistep treatment; Structure is simple, and few easy workout part, because ball milling circular motion can avoid the generation of scale formation in tower.Simultaneously the liquid film on filling ball surface is the main occasion of gas-liquid mass transfer, and is in the state of continuous renewal, and thus tower inner transmission matter, heat transfer efficiency are high, are applicable to the various mass transfer reactions in chemical reaction process.
Anion high voltage electrostatic device adopts honeycomb fashion electrion, and adopts perpendicular dress following current air intake, forms 360 degree of comprehensive interceptions in cross section, does not have dead angle.All dust, organic object are effectively caught absorption, when dust, organic substance absorption are a certain amount of, import in the disposal box of bottom under forward airflow function and Action of Gravity Field.Anion high voltage electrostatic device discharge voltage is adjustable within the scope of 1.5-3 ten thousand volts.While electrion absorption, every platform many groups electric field can produce the every platform O of a large amount of ozone
3>5000mg/h.Consequent a large amount of low temperature plasma O
3.
Process organic exhaust gas principle is: in the low temperature plasma of dielectric barrier discharge (DBD) occurs, first these waste gas factors are opened into fragment after being bombarded by high energy electron, there is comparatively complicated chemical reaction in the debris particles coming that the waste gas factor is dissociated and oxygen, is degraded to CO
2and H
2o etc.Adopt the barrier discharge low-temperature plasma technology of two medium, belong to dry process, without any need for adsorbent, catalyst and other any combustion-supporting fuel, only need adopt 220V alternating current, oscillation boosting through high frequency pulse generator obtains high-frequency impulse electric field, produce high-energy electron, stench, organic gas molecule in bombardment waste gas decomposition.Product type selection adopts the zinc-iron electric field of common corrosion-free flue dust or very strong stainless steel 304,316 electric fields of strong acid and strong base corrosivity, or the Water-cooling circulating formula under worst hot case closes electric field.
In addition, active carbon dust suction tower was with single-activity carbon purifying was different in the past, and activated carbon active carbon on cooperation anion high-pressure electrostatic precipitation desorption engineering application only need adsorb a small amount of organic exhaust gas of escaping.Because excessive ozone itself is also a kind of pollution, and give out a kind of stench, in the end one-level increase charcoal absorption can be adsorbed completely stench for unnecessary ozone, because ozone has very strong oxidation activity, so active carbon is while absorption, ozone can under natural normal temperature and air in combination with oxygen from new reduction, reach the resurrection again of active carbon, make the repeatedly circular flow that active carbon can be permanently effective, extend the use replacement cycle of active carbon, 1 year two to three times replacings meet the demands completely.
