Description
Technical field
The utility model relates to technical field of environmental protection facilities, especially a kind of wet-method desulfurized fume processing unit.
Background technique
It is administered about current domestic atmospheric haze, wet desulphurization exhaust emissions is that arch-criminal is gradually held by experts and scholars
Recognize, control wet desulphurization tail gas saturation vapour discharge is the key that administer haze.
According to external experience, wet desulphurization island usually requires installation smoke re-heater and (claims GGH, Gas gas in the industry
Heater), flue-gas temperature 80 degree or more are lifted to discharge.It is discharged using 80 degree or more high-temperature flue gas, this is in many flourishing states
Family is to discharge rigid standard.For example, " large-scale combustion apparatus method " regulation of Germany, chimney inlet temperature must not be lower than 72 DEG C；English
State provides that exhaust gas temperature must not be lower than 80 DEG C, and Japan's regulation exhaust gas temperature is at 90-100 DEG C.It is using the technique that GGH heats flue gas
External early mature technology, but occur new problem, GGH seriously corroded, system jams in China's large area.It removes other
Road flue, when GGH goes wrong and needs repairing, boiler is unable to operate normally.So the GGH built earliest is gradually removed, after
Wet desulphurization is built at all just without GGH.Leading to domestic wet desulphurization tail gas is the saturation vapour discharge of temperature 60 C or so, chimney
There are a large amount of condensing water vapors in outlet.
Desulfidation tail gas processing is bad, and a large amount of condensation vapors just will appear a large amount of gypsum rains near chimney.Even if not occurring
Gypsum rain, a large amount of calcium sulfate, which are diffused into atmosphere, forms aerosol, just will appear haze phenomenon when air humidity is sufficiently large.
So how to provide a kind of wet-method desulfurized fume processing unit, solve because of the too low bring of exhaust emissions temperature
Many problem of environmental pollutions are current those skilled in the art technical problems urgently to be resolved.
Utility model content
In view of this, the present invention provides a kind of wet-method desulfurized fume processing unit, solution is deposited in the prior art
Defect, concrete scheme is as follows:
A kind of wet-method desulfurized fume processing unit is connect including wet desulfuration tower 10 and with institute wet desulfuration tower 10
Former flue gas pipeline 20 and neat stress pipeline 21 are additionally provided with side between the neat stress pipeline 21 and the former flue gas pipeline 20
Siphunculus road 30, the bypass line 30 are equipped with regulating valve 31, and the outlet end of the neat stress pipeline 21 is connected with filler desulfurization
Tower 40, desulfurization filler 41 is equipped with inside the filler desulfurizing tower 40, and the filler desulfurizing tower is connect with discharge pipe 22.
Specifically, the main component of the desulfurization filler 41 is CaO, CaOH.
Specifically, it is 72 degrees Celsius that the regulating valve 31, which adjusts the mixed gas temperature entered in the filler desulfurizing tower 40,
More than.
Specifically, it is 80 degrees Celsius that the regulating valve 31, which adjusts the mixed gas temperature entered in the filler desulfurizing tower 40,
Or 90 degrees Celsius or 100 degrees Celsius.
The utility model adds flue gas mixing by-pass line between wet desulphurization device inlet and outlet flue, and setting is adjusted
Valve is exported between chimney in wet desulphurization neat stress and adds filler desulfurizing tower, and import is connect with neat stress flue, outlet and cigarette
Chimney connection, compared with prior art, has the advantage, that 1, instead of traditional GGH system, solves traditional GGH system gas leakage, corruption
The problems such as erosion, system jams.2, it solves chimney breast and a large amount of white cigarette (condensing water vapor) phenomenons occurs.
