Description
Technical field
The present invention relates to boiler, sintering device flue gas discharge treatment method technical field, specifically a kind of cooling condensation
With dewatering integrated elimination " white cigarette " method.
Background technology
In wet desulphurization machine set system, the temperature of chimney breast gas is generally 40-50 DEG C or so, and flue gas is typically
Saturation wet flue gas contains a large amount of vapor in flue gas.After flue gas is discharged by chimney, in the surrounding air relatively low into temperature, by
Relatively low in the saturation specific humidity of ambient air, the vapor in flue gas can condense to form plume, be exactly institute in terms of people's vision
" white cigarette " of meaning, it is serious also " chimney rain " to be formed in chimney peripheral extent.Particularly in winter, this phenomenon is brighter
It is aobvious.
In the prior art, the method for universal elimination " white cigarette " is essentially all that flue gas is heated, flue gas method
No doubt can achieve the effect that remove " white cigarette ", the shortcomings of but investment cost is big, long construction period, operating cost is high.
Northerly winter, since air themperature is relatively low.If it is cold in advance to be cooled down to " white cigarette " using Cryogenic air
It is solidifying, it is excluded again after reducing humidity, a kind of preferable processing mode of can yet be regarded as.
Invention content
The purpose of the present invention is to provide a kind of cooling condensation and dewatering integrated elimination " white cigarette " method, for solving to drop
The technical issues of low wet desulphurization " white cigarette " humidity.
The technical scheme adopted by the invention to solve the technical problem is that：
A kind of cooling condensation and dewatering integrated elimination " white cigarette " method, include the following steps：
It flows lower section of the hot gas out of chimney to top；
Cold wind is injected, and pass through air nozzle to cigarette into the ventilation endless tube being circumferentially positioned at around chimney by temperature-dropping fan
Hot gas in chimney uniformly sprays cold air；
The condensed gas liquid mixture that cools down enters in the cyclone separator of top；
Cyclone separator makes gas liquid mixture generate centrifugal movement, and the liquid detached in gas-liquid mixed body is got rid of to chimney
Wall is assembled, and flows downward along inner wall of stack；The gas detached in gas-liquid mixed body, is discharged along chimney breast；
The liquid to flow downward along inner wall of stack, into around setting inner wall of stack on collecting tank in, and by with collection
The drain pipe of liquid bath connection is expelled to the outside of chimney.
Further, temperature-dropping fan temperature of injection cold wind into ventilation endless tube is -5 DEG C to+5 DEG C ranges.
Further, the ventilation endless tube is stretched to by air jet pipe in chimney, and air nozzle is arranged on the front end of air jet pipe.
Further, the air nozzle is uniformly circumferentially positioned at the inside of chimney.
The effect provided in invention content is only the effect of embodiment rather than invents all whole effects, above-mentioned
It is had the following advantages that in technical solution or advantageous effect：
Before hot gas discharges chimney, in advance to the condensation of wet flue gas body forced cooling, dehydration；Meanwhile flue gas is diluted.Through
Flue gas discharge chimney of crossing that treated, " white cigarette " will significantly reduce；
This method is easy to operate, cost is relatively low, and good Social benefit and economic benefit is brought to society.

As shown in Figure 1, a kind of cool down condensation and the dewatering integrated device for eliminating " white cigarette ", including temperature-dropping fan 1, ventilation
Endless tube 2, cyclone separator 3 and collecting tank 4.
The temperature-dropping fan 1 is mounted on the outside of chimney 7, and temperature-dropping fan 1 is for inputting cold air into chimney 7, and cool down wind
The outlet side of machine 1 is connected with the inlet end of the ventilation endless tube 2.In winter, temperature-dropping fan 1 can directly draw extraneous cold sky
Gas, when other season external temperatures are higher, the inlet end of temperature-dropping fan 1 can connect cold wind equipment；The temperature of cold wind is -5
To+5 DEG C of ranges.The ventilation endless tube 2 is circumferentially positioned at by supporting rack around chimney 7, is uniformly provided on endless tube 2 of divulging information more
A air jet pipe 5 is stretched in chimney 7, and the front end of air jet pipe 5 is equipped with air nozzle 6；The air nozzle 6 is used for the bigger into chimney 7
The external cold air injected of uniform sprinkling of range, so as to which cold air be made to be come into full contact with the hot gas in chimney 7, with temperature with high efficiency.Institute
The cyclone separator 3 stated is mounted on by separator support base inside the chimney 7, and is located at the top of the air nozzle 6,
