Abstract
A kind of flue gas of cooling and dehumidifying disappears white system and method, it is related to flue gas desulfurization and flue gas eliminating white smoke process system and method, including desulfurizing tower, the heat medium water closed cycle that temperature descending section heat exchanger and warming-up section heat exchanger are constituted, the cooling water unit that cooling water inlet pipe, cool water shower pipe, drip tray, cooling water return pipe are constituted；Former cigarette enters desulfurizing tower through temperature descending section heat exchanger after being cooled down by heat medium water, the flue gas after desulfurization is further cooling through cooling water, dehumidifies, enters warming-up section heat exchanger after dedusting, is discharged into atmosphere through chimney after being heated by heat medium water；It humidity of flue gas is reduced, reduces flue gas by cooling realize of the cooling water to net cigarette and disappears white heat load, promote flue gas ash removal efficiency, flue gas ash removal, dehumidification efficiency are further promoted to the cooling of net cigarette by cooling water, utilize the net cigarette of the heat of former cigarette, the flue gas degree of superheat after further increasing dehumidifying, it realizes and eliminates white cigarette, reduces the discharge of dust and steam, and reduce the investment of entire desulfurizing technology system.
Description
Technical field
Disappear white system and method the present invention relates to the flue gas of flue gas desulfurization application field more particularly to cooling and dehumidifying.
Background technique
With the reality of " fossil-fuel power plant atmospheric pollutant emission standard " (GB13226-2011) that national environmental protection portion promulgates
It applies, it is desirable that coal-burning boiler dust emission standard reaches 30mg/Nm3, SO2Content distinguishes control by newly-built and existing power plant and exists
100mg/m3、200mg/m3, key area flue dust and SO from now on2Discharge amount is controlled in 20mg/m3,50mg/m3.It is increasingly stringenter
Atmosphere pollutants emission standards, force coal-burning power plant and other coal-burning boiler enterprises to need to change flue gas emission
It makes, to meet ultra-clean emission request.
Coal-burning boiler generates a large amount of dust, sulfur dioxide, sulfur trioxide and nitrogen using coal as the energy in process of production
Oxide, currently, coal-burning boiler, which generallys use Gypsum Wet technology, carries out flue gas desulfurization processing.
However, big using the humidity of flue gas after Gypsum Wet technology desulfurization, in discharge process, flue gas with
Atmosphere mixes temperature in diffusion process and reduces, and the elutriation in flue gas goes out, and forms white haze on chimney periphery, is commonly called as " plume ", in recent years
Come studies have shown that plume, which is formed, certain facilitation to haze, at present on Shanghai and other places, put into effect relevant policies,
It is required that administering plume problem.
To solve the above-mentioned problems, flue gas temperature rise heat exchanger is mainly arranged in the prior art between desulfurizing tower and chimney,
" plume " that condensation of moisture in flue gas generates is solved the problems, such as by promoting flue-gas temperature, but effect is all not so good, mainly because
Are as follows:
(1) to avoid condensation of moisture in flue gas, need to be substantially improved flue-gas temperature, flue gas temperature rise heat exchanger thermic load is huge
Greatly；
(2) affected by hot loading limits, and flue gas temperature rise heat exchanger is bulky, and existing apparatus is mostly original plant modification item
Mesh, it is limited using space, it is unable to satisfy actual needs；
(3) presentation can only be solved the problems, such as to flue gas heating, that is, eliminated macroscopic " white haze ", discharge entrained in flue gas
Steam there is no reducing, therefore there is no substantive realization emission reductions, so also very limited to the influence for administering haze.
Summary of the invention
It eliminates white " plume ", core is the steam discharge amount reduced in flue gas, while improving insatiable hunger in flue gas as far as possible
With the degree of superheat of vapor.And the present situation of existing domestic device is combined, the thermic load of flue gas temperature rise heat exchanger how is reduced, existing
Have the place of device, framework conditions it is all very harsh under the premise of solve flue gas heating and steam emission reduction, become and solve the problems, such as
It is crucial.
Analyze for these reasons, the present invention from two aspects:
1) moisture content in flue gas, substantial realization emission reduction are reduced；
2) thermic load for reducing flue gas temperature rise heat exchanger, reduces the outer dimension and weight of equipment of flue gas heat-exchange unit, meets
Demand is transformed in existing apparatus.
By reducing the water capacity in flue gas to flue gas cool-down, and then the moisture content in flue gas is reduced, while passing through spray
The further washing, purifying of dust in flue gas is reduced dust and pollutant in flue gas emission by leaching effect, realizes real meaning
On emission reduction；The moisture content in flue gas reduces simultaneously, under the premise of realizing same steam superheat, flue gas temperature rise heat exchanger
Thermic load be greatly reduced, and then reduce flue gas heat-exchange unit outer dimension and weight, meet plant modification requirement.
