Abstract

The utility model discloses a double-inlet flue desulfurization device, comprising a desulfurization tower, wherein a smoke inlet is arranged at the top of the desulfurization tower and a demister is arranged below a smoke outlet in the desulfurization tower; a three-layer spraying device is arranged below the demister and the three-layer spraying device conveys circulating liquid through an absorption liquid circulating system; an oxidization tank is arranged at the bottom of the desulfurization tower; the wall of the desulfurization tower is respectively provided with a first inlet flue and a second inlet flue; the first inlet flue and the second inlet flue are located between the three-layer spraying device and the oxidization tank; the first inlet flue is lower than the second inlet flue; and the first inlet flue and the second inlet flue are connected with pressurizing air blowers. With the adoption of the double-inlet flue, a convection area between the inlet smoke and the circulating absorption liquid can be efficiently increased, so that the reaction efficiency of the inlet smoke and the circulating absorption liquid is improved, the removing rate of SO2 is improved and the pollution to an environment is reduced.

Description

Two gas approach desulfurizers
Technical field
The utility model relates to a kind of exhaust gas processing device, and particularly a kind of pair of gas approach desulfurizer can be efficiently with flue gas and the even hybrid reaction of circulating absorption solution.
Background technology
It is the country of main energy sources with the coal that China is one, in the long term from now on, in the power industry is that main energy resource structure can not change with coal, more can not reduce the consumption of coal.Power plant generates electricity as main fuel with coal, and coal directly burning discharges a large amount of SO2, causes air environmental pollution, and along with increasing progressively of installed capacity, the discharge capacity of SO2 is also in continuous increase.This becomes global warming, produces the main cause of greenhouse effects, so reduce the discharge capacity of SO2, seems important and urgent further.At present, commonly used is ammonia-process desulfurization technique, and flue gas is to adopt the single flue inlet to feed the desulfurizing tower import in the ammonia-process desulfurization technique, and the mixed effect of flue gas and absorption liquid is bad, still contains more SO2 in the tail gas that causes discharging, and does not reach expected effect.
The utility model content
The technical problem that the utility model will solve is: in order to overcome the problems referred to above, a kind of pair of gas approach desulfurizer is provided, its increase efficiently import flue gas and circulating absorption solution to flow area, thereby improve the reaction efficiency of import flue gas and circulating absorption solution.
The utility model solves the technical scheme that its technical problem adopted: a kind of pair of gas approach desulfurizer, comprise desulfurizing tower, and the desulfurizing tower top is provided with exhanst gas outlet; The exhanst gas outlet below is provided with demister in the desulfurizing tower; The demister below is provided with three layers of spray equipment, and three layers of spray equipment are through absorption liquid circulatory system delivery cycle liquid, and the desulfurizing tower bottom is an oxidation pond; Have first inlet flue duct and second inlet flue duct on the desulfurizing tower wall; First inlet flue duct and second inlet flue duct are between three layers of spray equipment and oxidation pond, and first inlet flue duct is lower than second inlet flue duct, and first inlet flue duct and second inlet flue duct all are connected with booster fan.
Be equipped with the slope that is connected with the desulfurizing tower wall on described first inlet flue duct and second inlet flue duct, this slope extends upward, and gets into flue to prevent absorption liquid.
The beneficial effect of the utility model is: adopt two gas approach, can increase efficiently import flue gas and circulating absorption solution to flow area, thereby improve the reaction efficiency of import flue gas and circulating absorption solution, the extrusion rate of raising SO2, minimizing is to the pollution of environment.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
As shown in Figure 1, a kind of pair of gas approach desulfurizer comprises desulfurizing tower 4; Desulfurizing tower 4 tops are provided with exhanst gas outlet 14, and exhanst gas outlet 14 belows are provided with demister 13 in the desulfurizing tower 4, and demister 13 belows are provided with three layers of spray equipment 12; Three layers of spray equipment 12 have nozzle 15 through absorption liquid circulatory system delivery cycle liquid on three layers of spray equipment 12, and the absorption liquid circulatory system comprises ammonia tank 10, ammonia pump 9, circulating pump 2 and the shower 11 that links to each other successively; Shower 11 is communicated with three layers of spray equipment 12; Desulfurizing tower 4 bottoms are oxidation pond 1, and oxidation pond 1 is connected with oxidation fan 8 through air inlet pipe 7, and air inlet pipe 7 is provided with air intake branch 16 and feeds in the oxidation pond 1; Have first inlet flue duct 5 and second inlet flue duct 6 on desulfurizing tower 1 wall; First inlet flue duct 5 and second inlet flue duct 6 are between three layers of spray equipment 12 and oxidation pond 18, and first inlet flue duct 5 is lower than second inlet flue duct, 6, the first inlet flue ducts 5 and second inlet flue duct 6 all is connected with booster fan 17,18.
As shown in Figure 1, be equipped with the slope that is connected with desulfurizing tower 1 wall on first inlet flue duct 5 and second inlet flue duct 6, this slope extends upward, and gets into flue to prevent absorption liquid.
The two gas approach desulfurizing tower devices of the utility model comprise flue gas system, the absorption liquid circulatory system, oxidation air system, and its operation principle is following:
Flue gas system: boiler smoke is after booster fan 17,18 pressurizations; Through flue entrance 5; 6 get into desulfurizing towers, and after the absorption liquid convection current hybrid reaction of nozzle 15 ejections of three layers of spray equipment 12, flue outlet 14 enters chimney from the desulfurizing tower top through demister 13.
The absorption liquid circulatory system: the utility model desulfurizing tower 4 is used for the ammonia process of desulfurization; Absorption liquid is an ammoniacal liquor; Ammonia tank 10 carries the back to get into desulfurizing tower 1 bottom through ammonia pump 9, and in the running, circulating pump 2 is transported to shower 11 with the bottom absorption liquid through circulation fluid outlet 3; Through three layers of spray equipment 12, nozzle 15 spray backs and the flue gas hybrid reaction that gets into desulfurizing tower 4.
The oxidation air system: when not blasting air, circulation absorbs slurries and has SO 3 2-, HSO 3 -, will produce common-ion effect, reduce desulfurization rate, so add the oxidation air system in the desulfurizing tower bottom, the air of oxidation fan 8 gets into desulfurizing towers through air inlet pipe 7, adopts the mode of many air intake branches 16, makes oxidation air and absorption slurries homogeneous reaction.
