Operation principle: 28 pairs of each water pumps of electric cabinet and valve are controlled, and the flue gas that comes out from cremator 27 has been removed the most of dioxin in the flue gas after the secondary combustion chamber burning; Temperature can reach flue gas more than 1000 ℃ through the heat exchanger chilling then, makes its temperature below 250 ℃, in the desulfurization and dedusting tower; Flue gas has increased downward flow velocity after Venturi tube 10, flue gas directly is blown in the water that is amassed the tower body bottom, and flue gas is after washing; From water, upwards overflow, upwards get into the ball milling layer through the water conservancy diversion flaggy, the course of work of this ball milling layer is the adjustable dynamically mode of operation of many times of venturi; With the variable mode of dynamic rotation ball milling, rotation when the cremator operation changes, self-excitation, ball milling change synchronously, explain that with conventional principles will have several ten thousand little venturi of static state exactly now becomes a hundreds of thousands dynamic venturi principle; Increase liquid gas contact area and mass-transfer efficiency to greatest extent, when dynamic motion, impact and reverse liquid spraying is the inner-tower filling material ball to do the ball milling circular motion under half suspended state through ascending air; Make the corresponding reduction of wind speed resistance; Reach the desulfurization and dedusting effect, solved problems such as equipment scaling, obstruction, desulfuration efficiency can reach more than 95%; Efficiency of dust collection adapts to the dynamic change scope more than 45% more than 99%; System's each item technical indicator is reached advanced world standards; Floor space is little, operating cost is low, accommodation can comprise that any desulfurizing agent uses in the present WFGD scope, also adapts to various single udst separations, organic exhaust gas biodegradation purification and purifying and recovering system simultaneously.Solved a series of difficult problems that have a strong impact on mass transfer rate in the prior art simultaneously, make it to have: the gas, the liquid contact-making surface that have solved traditional static sulfuration bed fillers are little, the unsettled difficult problem of turbulent bed stuffing operation; Absorption liquid is fully used and consumption reduces, and the pressure and the degree of atomization of absorption liquid do not had strict demand, has reduced operating cost; Need not to increase in addition blast and can reach low-resistance, mass transfer effect efficiently; The absorption liquid circulatory system that the double loop is above be can realize, multi-stage diffluence and liquid phase multistep treatment reached; Simple in structure, few easy workout part can be avoided the generation of scale formation in the tower because of the ball milling circular motion.Simultaneously the liquid film on filling ball surface is the main occasion of gas-liquid mass transfer, and is in the state of continual renovation, thereby tower inner transmission matter, heat transfer efficiency are high, are applicable to the various mass transfer reactions in the chemical reaction process.
The anion high voltage electrostatic device adopts the honeycomb fashion electrion, and adopts perpendicular dress following current air intake, forms the comprehensive interception in 360 degree cross sections, does not have the dead angle.All dust, organic object are effectively caught absorption, when dust, organic substance adsorb when a certain amount of, are forward importing in the disposal box of bottom under air-flow effect and the gravity effect.Anion high voltage electrostatic device discharge voltage is adjustable in ten thousand volts of scopes of 1.5-3.Every many group electric fields can produce every O of a large amount of ozone in electrion absorption
3>5000mg/h.Consequent a large amount of low temperature plasma O
3
Handling the organic exhaust gas principle is: in the low temperature plasma of dielectric barrier discharge (DBD) takes place; These waste gas factors at first are opened into fragment after being bombarded by high energy electron; Comparatively complicated chemical reaction takes place in debris particles coming that the waste gas factor is dissociated and oxygen, is degraded to CO

2O etc.Adopt the barrier discharge low-temperature plasma technology of two media; Belong to dry process; Without any need for adsorbent, catalyst and other any combustion-supporting fuel, only need to adopt the 220V alternating current, through the oscillation boosting acquisition high-frequency impulse electric field of high frequency pulse generator; Produce high-energy electron, stench, organic gas molecule in the bombardment waste gas decomposition.On the product type selecting, adopt zinc-iron electric field or very strong stainless steel 304,316 electric fields of strong acid and strong base corrosivity, the perhaps circulating sealing electric field of the water-cooled under the worst hot case of common nothing corrosion flue dust.
In addition, active carbon dust suction tower was with the 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 the organic exhaust gas of a small amount of escape.Because of excessive ozone itself also is a kind of pollution; And give out a kind of smelling as of rotten fish, the charcoal absorption of one-level increase in the end can be the stench absorption fully of redundant ozone, because of ozone has very strong oxidation activity; So active carbon is in absorption; Ozone can be under natural normal temperature with airborne combination with oxygen from new reduction, reach the resurrection once more of active carbon, make the repeatedly circular flow that active carbon can be permanently effective; Prolong the use replacement cycle of active carbon, 1 year two to three times replacings meet the demands fully.
The above is a preferred implementation of the present invention, can not limit the present invention's interest field certainly with this.Should be pointed out that for those skilled in the art, technical scheme of the present invention is made amendment or is equal to replacement, do not break away from protection scope of the present invention.
