Description
Technical field
The utility model relates to the wet purification equipment of steelmaking converter flue gas, specifically is a kind of wet cooling tower.
Background technology
At present, steelmaking converter flue gas wet purification equipment of the prior art adopts the two-stage venturi scrubber that flue gas is lowered the temperature and dust removal process more.Wherein, first order Venturi tube mainly is to the processing of lowering the temperature of high temperature dust flue gas, also plays the effect of thick dedusting simultaneously; Second level Venturi tube mainly plays smart dedusting.The characteristics of first order Venturi tube be temperature reduction performance than higher, but equipment resistance is bigger, is about 3000～4000 handkerchiefs, water consumption height simultaneously, energy consumption is bigger.In order to overcome the high-drag of Venturi tube, the energy consumption of blower fan also must maintain higher level.Adopt first order Venturi tube to the processing of lowering the temperature of steelmaking converter flue gas, it is big to exist equipment resistance, the problem that energy consumption is high.
The utility model content
The purpose of this utility model provides a kind of wet cooling tower, and to solve in the first order Venturi tube cooling dedusting during stage, equipment resistance is big, the problem that energy consumption is high.
The purpose of this utility model is to realize by following technical scheme.The utility model wet cooling tower comprises water-cooled contraction section, overflow water seal, also comprises tower body, last spray gun, following spray gun;
Described tower body is a cylindrical member, and its top arrival end is equipped with water-cooled contraction section and overflow water seal, in described tower body, be equipped with described on spray gun and be positioned at described spray gun down below the spray gun, have sewage draining exit and exhanst gas outlet in the bottom of described tower body.
Described upward spray gun is equally distributed in the horizontal direction.
The particulate water smoke of the last spray gun ejection in the tower body fully mixes with flue gas, high-temperature flue gas is cooled off in the water smoke evaporation, be reduced to about 70 ℃ rapidly, in order to guarantee that water smoke and flue gas have the sufficient time to mix, the flow velocity of hot flue gas is slower, be that 4～5 meter per seconds get final product, make the cooling water of the overwhelming majority can both be used for evaporation, can not waste; And only need blast 300～500 handkerchiefs can keep this flue gas flow rate, reduced the consumption of the power and the water of blower fan widely.And prior art Venturi tube cool-down method, because of the flue gas flow at high speed water spraying atomization in the Venturi tube; The blast that needs is 3000～4000 handkerchiefs, and water consumption is also much bigger.
The particle diameter of the cooling water droplet of the following spray gun ejection in the tower body is bigger, and it becomes the dried smoke catching that settles down in the flue gas wet grit and fall at the bottom of the tower, discharges through sewage draining exit.Discharge from the exhanst gas outlet pipeline of tower body through the flue gas after cooling and the thick dedusting.
In sum, the utility model can be lowered the temperature fast significantly, significantly saves power and water again.

The specific embodiment
Be illustrated in figure 1 as the structural representation of the utility model wet cooling tower, comprise water-cooled contraction section 1, overflow water seal 2, tower body 3, last spray gun 5, following spray gun 6;
Described tower body 3 is a cylindrical member, its top arrival end is equipped with water-cooled contraction section 1 and overflow water seal 2, in described tower body 3, be equipped with described on spray gun 5 and be positioned at described spray gun 6 down below the spray gun 5, have sewage draining exit 4 and exhanst gas outlet 7 in the bottom of described tower body 3.Described upward spray gun 5 is in the horizontal direction, and many evenly distribute, and last spray gun 5 and following spray gun 6 are all worn the people from tower body 3 outsides, spray in tower body 3;
Also can be other forms, for example can be provided with spray gun 5 (not shown) on the multilayer.Last spray gun 5 ejection particulate water smokes fully mix with the flue gas that flows at a slow speed, and water smoke is fully evaporated, and make the high-temperature flue gas cooling, reduce the temperature to about 70 ℃ rapidly; The bigger cooling water droplet of particle diameter of following spray guns 6 ejections in the tower body 3 is used for dried smoke catching that flue gas is settled down, becomes wet grit and falls at the bottom of the tower.
When the utility model is worked, the flue gas that comes out from steel-smelting revolving furnace smoke canal, the water-cooled of flowing through from top contraction section 1 enters, water-cooled contraction section 1 is a pipe heat exchanger, inside and outside import department, be covered with cooling tube, all force cooling in each pipe, carry out the heat exchange cooling, make flue gas tentatively cool to about 900 ℃ with cooling water and high-temperature flue gas with cooling water.Flue gas enters in the tower body 3 then, fully mixes with flue gas with the particulate water smoke of last spray gun 5 ejection of tower body 3 internal upper parts, and water smoke is evaporated, and about 900 ℃ high-temperature flue gas is cooled off rapidly, is reduced to about 70 ℃.To spray water droplets with following spray gun 6 through transpiration-cooled flue gas again and capture grit, the water droplet that contains grit falls, and discharges from sewage draining exit 4; Gas after capturing grit is discharged from exhanst gas outlet 7.The effect of overflow water seal 2 be along tower body 3 peripheries to tower body 3 inwall continuous overflows, and the high-temperature flue gas entry place of tower body 3 played cooling effect and the flue dust that will be attached on tower body 3 inwalls dashes the bottom fall tower body 3, discharge.
The utility model wet cooling tower once used in 100 tons of converter gas recovery systems, replaced first order Venturi tube, and it is stable, and is respond well.After measured, the operational factor of this equipment is: smoke treatment amount 75000Nm
3/ h
72 ℃ of 900 ℃ of exit gas temperatures of entrance flue gas temperature
The about 400 handkerchief water consumption＜100t/h of equipment resistance.
Adopt original equipment first order venturi scrubber, handle the hot flue gas of same temperature, flow, the original equipment resistance is 3000～4000 handkerchiefs, and water consumption is 200t/h.
