Beneficial effect: the structure of the utility model utilizes that two-dimentional disturbance is stable to combine the design of special spray with the principle of three-dimensional turbulence; Desulfuration efficiency is increased, more reduced liquid-gas ratio, more have the meaning of degree of depth dedusting is arranged through the ultra tiny dust below the PM2.5 of static or sack cleaner.The utility model can make the reactivity of desulfurizing tower and sulfur dioxide in flue gas improve 10%~15%.Because efficient improves, the liquid-gas ratio that is adopted can reduce relatively, thereby reaches the effect of using water wisely, electricity consumption 5%~10%, has reduced energy resource consumption.
Description of drawings
Desulfurizing tower device sketch map in Fig. 1 the utility model Industrial Boiler flue gas desulphurization system.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
With reference to Fig. 1; Desulfurizing tower device in a kind of Industrial Boiler flue gas desulphurization system of present embodiment comprises: inlet flue duct 2, exhaust pass 12, tower body 1 that flue detects hole 3 and import spray equipment 4 the be interconnected inlet flue duct 2 of bottom and the exhaust pass 12 of head are housed; Between the inlet flue duct 2 and exhaust pass 12 that tower body 1 is inner, one-level spray equipment 5, eddy flow plate 6, secondary spray equipment 7, three grades of spray equipments 8, liquid-resisting device 9, one-level flap demister 10 and secondary flap demisters 11 are housed successively from bottom to top.Wherein one-level spray equipment 5, secondary spray equipment 7 and three grades of spray equipments 8 rotate 45 clockwise or counterclockwise successively oBe installed on tower body; And adopt the MP type solid-cone (type) nozzle of U.S. BETE company.When eddy flow plate 6 is installed on tower body 1, make the eddy flow plate page or leaf sheet elevation angle between 30-50 oBetween.
Workflow: the flue gas that contains the sulfide of sulfur dioxide etc. gets into through inlet flue duct 2, at first with 4 effects of import spray equipment, realizes the preliminary cooling and the dedusting of flue gas.Get into the tower body 1 inner flue gas even gas distribution that makes progress; Flue gas at first reacts with the spray liquid that one-level spray equipment 5 produces; Flue gas and the 6 blade effects of eddy flow plate subsequently reduce flue gas flow rate and mixed flue gas, and flue gas upwards reacts through the spray of secondary spray equipment 7 and three grades of spray equipments 8 successively.One-level at an angle to each other, secondary and three grades of spray equipments have improved the coverage rate that flue gas is sprayed greatly.Eddy flow plate 6 blade angles that eddy flow design is walked quickly and kept away in utilization are 40 degree, and the flue gas flow rate that slowed down has prolonged time of secondary and three grades of sprays, has improved the coverage rate that flue gas is sprayed equally.The increase of this coverage rate effectively raises the desulphurization reaction rate.Flue gas continues upwards to pass through liquid-resisting device 9, one-level flap demister 10 and secondary flap demister 11 successively, the flue gas drying that dewaters in this process.Last flue gas arrives tower body 1 head and discharges through outlet conduit 12.
The innovative point of the utility model is: the MP type solid-cone (type) nozzle that adopts U.S. BETE company; According to spray coverage rate 120%~200% (150% best results) design, each spraying layer rotates clockwise or counterclockwise 45 ° of weak areas of coverage that remedy down one deck spray step by step.
Be optimized in conjunction with existing eddy flow plate technique (25 ° of blade elevation angle degree), utilizing and walking quickly and keeping away the swirler blades elevation angle degree that eddy flow is designed to is 40 °.Under the certain situation of flue gas flow, reduce the flue gas flue gas flow rate with the method that increases sectional area, what can prolong is the incorporation time of the desulfurization spray liquid of 120%~200% (150% best results) with spraying coverage rate.
Combine the design of special spray with the principle of three-dimensional turbulence from two-dimentional disturbance is stable.Desulfuration efficiency is increased, more reduced liquid-gas ratio, more have the meaning of degree of depth dedusting is arranged through the ultra tiny dust below the PM2.5 of static or sack cleaner.
Above content is to combine optimal technical scheme to the further explain that the present invention did, and can not assert that the practical implementation of invention only limits to these explanations.Under the present invention, the those of ordinary skill of technical field, under the prerequisite that does not break away from design of the present invention, simple deduction and replacement can also be made, all protection scope of the present invention should be regarded as.
