Description
Technical field
Disappear white integrated treatment dress the present invention relates to tail gas disposal technique field, especially wastewater zero discharge and desulfurization fume
It sets and processing method.
Background technique
In China, flue gas desulfurization device has all been built in almost all of thermal power plant, wherein 95% or more is de- using wet process
Sulphur technique.Wet desulphurization device discharges desulfurization wastewater when running, while wet desulfurization flue gas contains above the average age for marriage saturated steam, if
Direct emission is not heated, smoke stack emission mouth will be caused to emit " white cigarette ", deteriorate local environmental quality around chimney and forms " vision "
Pollution.Due to the operation of a large amount of wet desulphurization devices, water pollution caused by Power Plant in China wet desulphurization discharge of wastewater is asked
Topic is got worse, and it is very prominent that wet desulfurization flue gas " white cigarette " discharges phenomenon.With the increasingly raising of China's environmental improvement level,
The environmental problem that desulfurization wastewater zero-emission and discharge " white cigarette " phenomenon that removes smoke will need to solve as another.
For the zero-emission for realizing waste water, there are mainly two types of for present solution:
First, heat medium is used steam as, waste water is concentrated by evaporation by using the waste water evaporator of steam, after evaporation and concentration
High-salt wastewater enter multiple-effect evaporation crystallization apparatus and generate the crystal salt and pure water for containing certain moisture, pure water reuse is realized wide
The wastewater zero discharge of justice.Main problem existing for the technique is: when in waste water contain calcium, magnesium compound such as calcium sulfate and magnesium sulfate
And when the solids such as flying dust, it is necessary to be pre-processed to waste water, pretreatment removes suspended matter or the waste water of precipitating and could use
Above-mentioned wastewater treatment equipment carries out advanced treating.This process requirement uses high-quality steam as heat source, and energy consumption is high, device
Initial cost is high, and the waste water of its processing has certain limitation, is not suitable for heat-engine plant desulfurized wastewater treatment.
Second, Waste water concentrating is carried out using high-temperature flue gas, makes waste water solution saturated crystallization, the waste water containing crystalline particle is again
It is dehydrated by dehydration equipment, there is the crystal salt of certain moisture content, dehydration filtrate returns to wastewater concentrator circulation and carries out
Condensing crystallizing realizes the wastewater zero discharge of broad sense.It is divided into Waste water concentrating in the treatment process principle and crystallization waste water is dehydrated two
Part, the crystallization process under Yao Shixian solution hypersaturated state, the Waste water concentrating multiplying power parameter of Waste water concentrating link is very big,
In this case, for the desulfurization wastewater containing ingredients such as magnesium sulfate, calcium sulfate, equipment scaling is asked during Waste water concentrating
Topic inevitably will seriously occur, and cannot achieve the continuous operation of device.
" white cigarette " phenomenon is emitted to eliminate heat-engine plant desulfurized flue gas smoke stack emission mouth, mainly in the following ways:
First, desulfurization fume is heated using flue gas heat-exchange unit, flue gas is made to become hot fume from saturated flue gas, is eliminated
" white cigarette "；Flue gas is heated using MGGH, the problem is that: investment is high, and energy consumption is high, and Technical Economy is lower.Second,
Using dedicated hygroscopic agent, free liquid water and part vapor in flue gas are adsorbed, reduces smoke moisture, eliminate and is improved " white
Cigarette " discharges phenomenon, but the technology is immature, is still not clear after processing with the presence or absence of secondary pollution, while there is also investments and fortune
The costly disadvantage of row.
