Background technique
As economic constantly advances, social is constantly progressive, and also brings more and more environmental problems.Industry
Flue gas is one of primary pollution source of atmosphere, and nitrogen, sulfur oxide are capable of forming deep-etching after being combined with water containing there are many
The acid solution of property, brings significant damage to exhaust apparatus, to environment.
Currently, industrial smoke mainly has direct emission and discharges two kinds of forms again after wet desulphurization.The work of direct emission
Industry flue gas, temperature is high, humidity is low, is able to maintain the drying of chimney, thus chimney is not caused significantly to corrode, however it is this
Nitrogen, sulfur oxide content are high in flue gas, and environmental pollution is larger.In contrast, many-sided based on environmental protection and cost of investment etc.
Consider, the Wet chimney scheme of wet desulphurization is carried out to flue gas, is still presently the most the mode of approval.
However Wet chimney scheme remains certain problem, wet desulphurization can remove the oxygen of most of sulphur in flue gas
Compound is but difficult to and completely eliminates pollutant in flue gas.And wet desulphurization can to introducing a large amount of vapor in flue gas,
Form the Low Temperature Wet white cigarette containing pollutant.This Low Temperature Wet white cigarette easily condenses in inner wall of stack, forms the acidity of strong corrosive
Solution causes serious corrosion to inner wall of stack.Simultaneously as temperature is low, nitrogen, the sulfur oxide contained in flue gas is difficult to expand
It dissipates, it is cumulative, it can also be polluted caused by surrounding enviroment.Therefore, take off white dehumidifying to the flue gas after desulfurization very necessary.
Taking off the white method generallyd use that dehumidifies at present is using flue gas heater, using steam or flue gas to the flue gas after desulfurization
Reach certain temperature, it is made to be difficult to condense, but this method energy consumption is very big, it is very uneconomical, it will cause the very big wave of energy
Take.
The white technique that takes off popular at this stage mainly carries out condensation dehydration and reheating, drop to flue gas using heat exchanger
The moisture content of low smoke evacuation.Flue gas is cooled to 45 DEG C or so from 50~60 DEG C or so first, a part of water is precipitated, flue gas is reduced and contains
Moisture；It recycles former fume afterheat that flue gas is heated to 70~80 DEG C or more from 45 DEG C or so, reduces flue gas relative humidity.It takes off white
Most important link is exactly to reduce flue gas moisture content in technique, and the flue gas after dehumidification by condensation device contains droplet, influences to take off white
Effect.
