Abstract

The utility model provides a dust collector collects that desulfurizing tower waste water integrated treatment system of recycling, desulfurization waste water at first accomplish the preliminary treatment through the sedimentation tank, and large -particle matter's in the waste water desorption is accomplished to the sedimentation tank, then in getting into the high -efficient whirlwind separation atomizer of arranging in the flue, high -efficient whirlwind separation atomizer flow area export from entering the mouth and diminishes gradually, through the heat of absorption flue gas, isolates the tiny particle thing that the crystallization was come out, through low reaches. Simultaneously, high -efficient whirlwind separation atomizer end is equipped with the nozzle, gets into the flue gas with the waste water atomizing, finally gets into to collect in the desulfurizing tower to utilize, accomplishes the useless treatment of water of desulfurization. The recycle of water purification is accomplished simultaneously to the impurity of this invention in can efficient desorption waste water, has practiced thrift the water resource, has realized the zero release of desulfurization waste water.

The sulfur method that current domestic coal-burning power plant commonly uses is wet process of FGD (WFGD), and the application in fields such as coal-burned industrial boiler, sintering flue gases of this technique increases the most increasingly.Desulfurization wastewater is mainly the discharge water on absorption tower during power plant boiler wet method desulfurization (limestone/gypsum method), the impurity contained in waste water mainly includes float, sulfate and heavy metal, it is all much wherein that national environmental standard requires the strict first kind pollutant controlled, existing desulfurization wastewater conventional processes is complicated, operation operational ton is big, it is difficult to automatically control, most power plant operation result is undesirable, waste water after process still contains the chloride ion of higher concentration, stronger to the corrosivity of metal and equipment, the waste water after processing is caused to put back into, cannot recycle.Based on this, need badly and to seek a kind of system that desulfurization wastewater can be carried out integrated treatment and recycling, to save the energy, and meet the requirement of environmental protection.
Utility model content
The purpose of this utility model is to improve above-mentioned unfavorable conditions, a kind of desulfurizing tower waste water integrated treatment reutilization system is provided, desulfurization wastewater can be processed by it, remove the various impurity components contained inside it, and treated waste water is recycled again, this system cost is relatively low, and good waste water treatment effect.
The technical solution of the utility model: a kind of desulfurizing tower waste water integrated treatment reutilization system, including the air preheater being positioned at flue, efficient cyclone separation nebulizer, electric cleaner, desulfurizing tower, wherein, electric cleaner is arranged on the flue between efficient cyclone separation nebulizer and desulfurizing tower, in efficient cyclone separation nebulizer then flue between air preheater and electric cleaner, described efficient cyclone separation nebulizer includes position waterwater entrance to its upper, swirl channel on its interior, and it is positioned at the multiple waste water atomizers outlet bottom it, described waterwater entrance is connected with the wastewater disposal basin of desulfurizing tower, described swirl channel is tapered into exporting its circulation area by entrance.
Further, also including sedimentation tank, it separates between nebulizer at desulfurizing tower with efficient cyclone, first precipitates the waste water of the waterwater entrance entering efficient rotary separation wind nebulizer.
Further, described efficient cyclone separation nebulizer is additionally provided with slag-drip opening, for the large granular impurity through cyclonic separation is discharged.
Compared with prior art, the beneficial effects of the utility model are: 1, utilize efficient cyclone separation nebulizer that waste water is carried out decontamination process, improve impurity treatment effect;2, efficient cyclone separation nebulizer absorbs the heat in flue during the impurity in waste water carries out cyclonic separation, makes waste water constantly heat up during decontamination, and finally sprays from atomizer, saves the process time, improves treatment effect;3, sedimentation tank is set, it is possible to one step ahead waste water is carried out precipitation process, removes its interior large granular impurity, improve treatment effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment, wherein 1-air preheater, 2-efficient cyclone separation nebulizer, 3-electric cleaner, 4-desulfurizing tower, 8-flue, 9-wastewater disposal basin, 10-sedimentation tank.
Fig. 2 is the structural representation of efficient cyclone separation nebulizer in this utility model embodiment, wherein 5-waterwater entrance, 6-jet expansion, 7-swirl channel, 11-slag-drip opening.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of desulfurizing tower waste water integrated treatment reutilization system, including the air preheater 1 being positioned at flue 8, efficient cyclone separation nebulizer 2, electric cleaner 3, desulfurizing tower 4, wherein, electric cleaner 3 is arranged on the flue 8 between efficient cyclone separation nebulizer 2 and desulfurizing tower 4, in efficient cyclone separation nebulizer 2 then flue between air preheater 1 and electric cleaner 3, described efficient cyclone separation nebulizer 2 includes position waterwater entrance 5 to its upper, swirl channel 7 on its interior, and it is positioned at the multiple waste water atomizers outlet 6 bottom it, described waterwater entrance 5 is connected with the wastewater disposal basin 9 of desulfurizing tower, described swirl channel 7 is tapered into exporting its circulation area by entrance.
Further, also including sedimentation tank 10, it separates between nebulizer 2 at desulfurizing tower 4 with efficient cyclone, first precipitates the waste water of the waterwater entrance 5 entering efficient rotary separation wind nebulizer 2.
Further, described efficient cyclone separation nebulizer 2 is additionally provided with slag-drip opening 11, for the large granular impurity through cyclonic separation is discharged.
nullWork process is as follows: first,The desulfurization wastewater produced through desulfurizing tower is introduced in sedimentation tank 10,Remove large-sized solid particle therein,Afterwards waste water is passed through efficient cyclone separation nebulizer 2,In efficient cyclone separation nebulizer 2,Waste water enters swirl channel 7 by waterwater entrance 5,In swirl channel 7,Owing to this swirl channel its circulation area from the inlet to the outlet is gradually reduced,Therefore,During waste water within it flows, its flow velocity is gradually increased,During eddy flow, impurity less for diameter contained in waste water is thrown on the wall of swirl channel 7,Remove the impurity that its interior diameter is less,Waste water in swirl channel 7 constantly absorbs the heat of flue gas during flowing afterwards,And atomization ejection in atomizer outlet 6,Waste water after ejection absorbs flue gas heat and evaporates,Solid particle is captured in then entering electric cleaner 3,In flue gas carries the waste water entrance desulfurizing tower 4 of steam condition afterwards,Carry out next step to recycle.
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment, supplements or use similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
