Abstract
A kind of method of desulfurization wastewater concentration, the technology mainly concentrated using newly-built or original pre-washing device to desulfurization wastewater.
Description
Technical field
The present invention relates to desulfurization wastewater processing technology field, in particular it relates to be taken off to thermal power plant, Industrial Stoves wet method
The method and device of sulphur Waste water concentrating processing.
Background technology
The wastewater treatment produced in thermal power plant, Industrial Stoves wet desulphurization is very unlikely to, and thoroughly side is compared at present
Method uses evaporative crystallization technique, at present using less；Also drying process with atomizing is used, it is several without application at present;Also will be de-
Sulphur waste water sprays into the flue of higher temperature（After air preheater）, the salinity in desulfurization wastewater is evaporated into powder salt with flue dust together
Caught by deduster, it is also few using achievement.
It is badly in need of wanting a kind of processing method of cheap and simple to handle desulfurization wastewater at present.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of energy-conservation, the method simple and easy to apply concentrated to desulfurization wastewater
And device
The present invention solve desulfurization wastewater concentration technical scheme be：
A kind of method of desulfurization wastewater concentration comprises the following steps：
S1, desulfurization wastewater collected to pre-washing case.
S2, pre-wash pump the desulfurization wastewater pre-washed in case be delivered to before desulfurizing tower in flue and pre-wash shower,
Or newly-built pre-wash shower.
S3, desulfurization wastewater are fallen in shower is pre-washed, and the dustless high-temperature flue gas before desulfurizing tower in flue gives up with desulfurization
Water carries out heat exchange, and partial desulfurization waste water becomes steam, into desulfurizing tower, and the drop of desulfurization wastewater, which is still fallen within, pre-washes collection
Device, subsequently into pre-washing melt pit.
S4, the desulfurization wastewater for pre-washing melt pit enter back into and pre-wash case.
It is 5 to 80 times of desulfurization wastewater yield to pre-wash desulfurization wastewater in case and the flow of circulation is beaten by pre-washing pump, in advance
Desulfurization of the dustless high-temperature flue gas to big flow after desulfurization wastewater and deduster that wash spray pipe is sprayed before desulfurizing tower is given up
Water carry out heat exchange evaporation desulfurization wastewater is concentrated, can be concentrated into former desulfurization wastewater water 1/10th or 20/
One.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention
Each component names are marked in accompanying drawing：
Flue 3-, which pre-washes shower 4- and pre-washes collection device 5-, before 1- desulfurizing tower 2- desulfurizing towers pre-washes
Melt pit 6- pre-washes pump 7- and pre-washes case 8- desulfurization wastewaters
Embodiment
With reference to embodiment and accompanying drawing, the present invention will be further described, but the implementation of the present invention is not limited to this.
As shown in figure 1, a kind of method of desulfurization wastewater concentration, comprises the following steps：
S1, desulfurization wastewater 8 collected to pre-washing case 7.
S2, pre-wash pump 6 desulfurization wastewater pre-washed in case 7 is delivered to before desulfurizing tower in flue and pre-wash shower
3, or newly-built pre-wash shower 3.
S3, desulfurization wastewater are fallen in shower 3 is pre-washed, the dustless high-temperature flue gas in flue 2 and desulfurization before desulfurizing tower
Waste water carries out heat exchange, and partial desulfurization waste water becomes steam, into desulfurizing tower 1, and the drop of desulfurization wastewater, which is still fallen within, to be pre-washed
Collection device 4, subsequently into pre-washing melt pit 5.
S4, the desulfurization wastewater for pre-washing melt pit 5 enter back into and pre-wash case 7.
It is 5 to 80 times of desulfurization wastewater yield to pre-wash desulfurization wastewater in case and the flow of circulation is beaten by pre-washing pump, in advance
Desulfurization of the dustless high-temperature flue gas to big flow after desulfurization wastewater and deduster that wash spray pipe is sprayed before desulfurizing tower is given up
Water carry out heat exchange evaporation desulfurization wastewater is concentrated, can be concentrated into former desulfurization wastewater water 1/10th or 20/
One.
Assuming that the yield of a certain power plant desulfurization wastewater is 15 tphs, then the desulfurization wastewater in washer box is by pre-washing pump
The flow for playing circulation is 75 to 1200 tphs, and the amount for being concentrated into last desulfurization wastewater is about 1.5 tons or 0.75 tph.
Claims (2)
1. a kind of method of desulfurization wastewater concentration, it is characterised in that comprise the following steps：S1, desulfurization wastewater 8 collected to prewashing
Wash case 7.S2, pre-wash pump 6 desulfurization wastewater pre-washed in case 7 be delivered to before desulfurizing tower in flue and pre-wash shower 3,
Or newly-built pre-wash shower 3.S3, desulfurization wastewater are fallen in shower 3 is pre-washed, dustless in flue 2 before desulfurizing tower
High-temperature flue gas carries out heat exchange with desulfurization wastewater, and partial desulfurization waste water becomes steam, into desulfurizing tower 1, the drop of desulfurization wastewater
Still fall within and pre-wash collection device 4, subsequently into pre-washing melt pit 5.S4, pre-wash melt pit 5 desulfurization wastewater enter back into it is pre-
Washer box 7.
2. according to claim 1, it is desulfurization wastewater yield by the flow for pre-washing 6 dozens of circulations of pump to pre-wash the desulfurization wastewater in case
5 to 80 times.
