Abstract
The present invention relates to a kind of flue gas treating process based on steam, the water smoke that flue gas is sprayed out in desulfurizing tower (2) with vapor and spray equipment (1) is combined, a part of water smoke falls at Sewage treatment (5) by deadweight and reclaimed, remaining water smoke is recycled at Sewage treatment (5) by dehumidification system (7), and flue gas is discharged by smoke exhaust pipe (6).
Description
Art
The present invention relates to a kind of flue gas treating process based on vapor.
Background technology
Contain the pernicious gases such as a large amount of sulfide and itrated compound in boiler smoke, it is necessary to remove corresponding pernicious gas, make it
Reach that discharge standard could be discharged.At present, known boiler flue gas purification uses dry cleaning method and wet purification method.It is dry
The formula method of purification carries out desulphurization denitration processing using lime, because sulfide and itrated compound are acidity, can occur with alkaline matter anti-
Should, but it is higher using dry cleaning method cost, also relate to Solid state fermentation.Wet purification method using water to sulfide at
Reason, because sulfide and itrated compound have strongly hydrophilic, can be only absorbed by the water.
Water heating is produced by vapor by high temperature, vapor runs into the relatively low flue gas of temperature, and condense turns into atmosphere
Water smoke.Mist particle diameter can reach 0.1mm.
The content of the invention
In order to overcome the problem of existing boiler smoke dry cleaning method cost is high, and wet purification method is further improved, this
A kind of flue gas treating process based on vapor of detailed description of the invention.
The technical solution adopted for the present invention to solve the technical problems is：Sprayed first with shower nozzle, water smoke is sprayed into desulfurization
Tower, according to the solubility of sulfur dioxide, generates sulfurous acid solution with water, while vapor is passed through into desulfurizing tower, is allowed to and flue gas
With reference to vapor forms water smoke in the air, and generation sulfurous acid is further combined with sulfur dioxide.A large amount of water smokes fall to receive by deadweight
Collection gets up, and remaining water smoke is collected by dehumidifying.
According to the favourable improvement of the present invention, vapor is cooled using spraying to promote to form water smoke.
According to another favourable improvement of the present invention, with the common sulfur dioxide absorption of the mode of spray water mist and vapor,
To increase absorption efficiency.
Brief description of the drawings
Fig. 1 is systematic schematic diagram
In figure：1. spray equipment；2. desulfurizing tower；3. smoke inlet；4. steam inlet；5. at Sewage treatment；6. smoke exhaust pipe；
7. dehumidification system.
Embodiment
Vapor enters desulfurizing tower (2) by steam inlet (4), and flue gas enters desulfurizing tower (2) by smoke inlet (3),
Spray equipment (1) is to desulfurizing tower (2) interior spray water mist.Vapor becomes water smoke, flue gas after being contacted with the water smoke of flue gas and spray
Sulfurous acid is generated after being combined with water smoke.A part of water smoke under deadweight because drop down onto at Sewage treatment (5), and remaining flue gas and water smoke enter
Enter dehumidification system (7), the water after dehumidifying is equally imported at Sewage treatment (5), remaining flue gas is discharged by smoke exhaust pipe (6).
Claims (2)
1. a kind of flue gas treating process based on vapor, comprises the following steps：
Steam enters desulfurizing tower (2) by steam inlet (4), and flue gas enters desulfurizing tower (2), spray dress by smoke inlet (3)
(1) is put to desulfurizing tower (2) interior spray water mist, the water smoke mixing of steam and flue gas and spray, a part of water smoke free-falling is entered
Enter at Sewage treatment (5), remaining flue gas and water smoke enter dehumidification system (7), the water after dehumidifying equally imports Sewage treatment
Locate (5), remaining flue gas is discharged by smoke exhaust pipe (6).
Characterized in that, water smoke and vapor that spray equipment is sprayed out jointly with flue gas blended absorbent sulfur dioxide.
2. technique according to claim 1, it is characterised in that the water smoke sprayed out using flue gas and spray equipment is steamed to water
Gas carries out the mixture after cooling combination and carries out water smoke recovery with the mode of condensation first.
