detailed description of the inventionwith reference to accompanying drawing, a kind of Novel desulfurizing dust removing device of the present invention, comprises the tower body of top tape outlet flue 16, flue 7 and circulating water pool 15; Its main points are provided with two soda lime water layer 9, bubble layer 5, spraying layer 4 and demist layer 1 in described tower body from the bottom to top successively; Described bubble layer 5, spraying layer 4, demist layer 1 and the position corresponding to outlet flue 16 are respectively equipped with manhole 3; The outer end of described flue 7 is provided with ring flange 8, and the inner of flue 7 is provided with the branched pipe inserting two soda lime water layers 9, and the lower end of branched pipe is connected with the transverse tube 12 of band venthole 13; The bottom of described tower body is provided with soil shifting opening 10; Above described transverse tube, the tower body wall at 1-5cm place is provided with the return duct 14 be communicated with circulating water pool 15; Described circulating water pool 15 is provided with the main-supply 11 connected by water pump; Described main-supply 11 is provided with three road branch showers, be connected with shower nozzle 2 in the spraying layer of the two road branch showers insertion tower bodies on main-supply 11 top, the inlet location that one branch's shower of lower 11 of main-supply inserts flue is connected with preposition shower nozzle 6.
Described transverse tube 12 has plurality of specifications to change, and up and down apart from adjustable; On the transverse tube 12 of different model, venthole 13 varies in size; Shower nozzle in described spraying layer is in row or layer apportion, and quantity is 2-4 row or layer; Described tower body and flue all adopt fiberglass to make; In-built saturated limewater, NaOH and 12 sodium alkyl benzene sulfonate mixed liquors in described circulating water pool 15, saturated limewater: NaOH: the weight proportion of 12 sodium alkyl benzene sulfonates is: 10000:3:3 ~ 5; Described pair of soda lime water layer 9, squeezes into tower body bottom by the mixed liquor in circulating water pool and is formed; Described bubble layer 5, by the mixed liquor in the two soda lime water layer in tower body bottom, blows formation via the flue gas sprayed from transverse tube venthole 13; Porous grate 17 is provided with above described bubble layer 5.
The present invention is made by fiberglass by Novel desulfurizing dust removing device, during use, ring flange is connected with the pipe of fume generating furnace, after flue gas enters flue 7, first through preposition shower nozzle 6 spraying cooling, then reach lime water layer by the venthole of transverse tube to emerge with the form of bubble, after arriving bubble layer, flue gas constantly broken bubble, become bubble make gaseous sulfide more fully with NaOH and calcium hydroxide reaction, again through further dedusting after flue gas arrival spraying layer, then discharged by outlet flue after demist layer.Water in circulating water pool through shower nozzle ejection after through bubble layer, arrive two soda lime water layer, then be back in circulating water pool by the return duct of side, regularly like this in pond, add a certain amount of surfactant 12 sodium alkyl benzene sulfonate, NaOH and fresh limewash mixed liquor.
Described demist layer 1, be made up of demister, it is mainly made up of fixtures such as waveform blade, plate, card articles, in the running of wet desulphurization, easily produces " mist " that particle diameter is 10--60 micron, " mist " is not only containing moisture, it is also dissolved with sulfuric acid, sulfate, sulfur dioxide etc., also causes staining and heavy corrosion of blower fan and flue, therefore simultaneously, wet desulfurizing process proposes the requirement of demist to absorption equipment, cleaned gas wanted demist before leaving absorption tower.
Demister is used for the drop that in dust arrester, gas is carried secretly, to ensure mass-transfer efficiency, effectively can remove the droplet of 3--5um.
The arrangement form of demister is modal has flat layout and roof type to arrange.
Demister is mainly made up of plate, supporting arrangement.Plate is made by macromolecular material (as polypropylene PP, FRP etc.) or the large class material of stainless steel (as 316L, 317L etc.) 2 usually.Generally be divided into streamlined and broken line type.
When the gas containing mist flows through demister with certain speed, due to the inertial impaction effect of gas, mist and corrugated sheet collide and by the drop gathered arrive greatly the gravity himself produced exceed making a concerted effort of the climbing power of gas and surface tension of liquid time, drop just gets off from corrugated sheet is separated on the surface.The structure that is folded to of demister corrugated sheet adds the chance that mist is captured more, and the mist be not removed is captured through identical effect at next turning, such repeated action, thus substantially increases demisting efficiency.Gas, by after wave-shaped plate demister, is substantially free of mist.Flue gas is by the bending channel of demister, under the effect of inertia force and gravity by the drop separation of carrying secretly in air-flow out: the flue gas after desulfurization flows through demister with certain speed, flue gas is changed the direction of motion rapidly, continuously, because of the effect of centrifugal force and inertia, droplet in flue gas strikes on demister blade and is captured down, droplet collects formation current, because of the effect of gravity, fall in slurry pool, achieve gas-liquid separation, make the flue gas flowing through demister reach demist and require rear discharge.
The demisting efficiency of demister increases with the increase of air velocity, and this is because flow velocity is high, and the inertia force acted on droplet is large, is conducive to the separation of gas-liquid.But the increase of flow velocity will cause SR to increase, and also make energy consumption increase.And the increase of flow velocity has certain limit, the too high meeting of flow velocity causes two sub-band water, thus reduces demisting efficiency.Usually flue gas flow rate during by the highest of demister section and again unlikely two sub-band water is defined as critical flow velocity, this speed is relevant with factors such as demister structure, system band Water l oad, airflow direction, demister arrangements.Design current velocity is generally selected in 3.5-5.5m/s.
Demister arrangement form has usually: in horizontal type, chevron shaped, V-shape, the large desulfurization absorption tower such as combined adopt chevron shaped layout more, and V-shape is arranged or combined layout (as rhombus, X-type).Conventional mesh mist eliminator (also known as mist eliminator, mist eliminator), the drop of 3 μm ~ 5 μm is greater than mainly for separating of diameter, operation principle: when the gas with liquid foam rises with certain speed, during by the woven wire of frame on grid, the effect of inertia that liquid foam rises makes liquid foam and filament collide and stick on the surface of filament.Liquid foam in filament surfaces spreads and the gravitational settling of liquid foam itself further, liquid foam is formed larger drop flow to it intertexture place along filament.Due to the capillarity of the wettable of filament, the surface tension of liquid and filament, make drop increasing, until when the gravity of himself exceedes making a concerted effort of buoyancy that gas rises and surface tension of liquid, just separated and fall, flow in the upstream device of container.As long as what the conditions such as operating gas velocity were selected works as, gas is by after wire mesh demister, and its foam removal efficiency can reach more than 97%, can reach the object removing mist completely.
During installation, the ventilation unit related to can adopt roots blower or air compressor machine.
