Abstract
The utility model provides a concentrated device of desulfurization waste water, contains washing box, prewashing in advance and washs pump, prewashing and wash that flue before collection device, the desulfurizing tower is washed to shower, prewashing, the pit is washed in prewashing, and concrete the connection is: desulfurization waste water get into in advance the washing box in proper order through prewashing wash the pump, the shower is washed in prewashing, then falls from the shower is washed in prewashing, the dustless high temperature flue gas before the desulfurizing tower in the flue carries out the heat exchange with desulfurization waste water, partial desulfurization waste water becomes steam, gets into the desulfurizing tower, the liquid drop of desulfurization waste water still falls into prewashing and washs collection device, then gets into prewashing and wash the pit, it is main that utilize newly -builtly or original washing device in advance carries out concentrated technique to desulfurization waste water. Can save the steam or the electric power energy in a large number, it is pollution -free, the concentration process of accomplishing desulfurization waste water clean completely.
Description
Technical field
This utility model relates to desulfurization wastewater processing technology field, in particular it relates to wet to thermal power plant, Industrial Stoves
The method and device of method desulfurization wastewater concentration.
Background technology
The waste water produced in thermal power plant, Industrial Stoves wet desulphurization processes and is very unlikely to, and compares side thoroughly at present
Method has employing evaporative crystallization technique, and application is less at present；Also there is employing drying process with atomizing, current several without application;Also having will be de-
Sulfur waste water sprays into the flue (after air preheater) of higher temperature, makes the salinity in desulfurization wastewater be evaporated into powder salt with flue dust together
Being caught by cleaner unit, application achievement is the most few.
It is badly in need of at present wanting the processing method of a kind of cheap and simple to process desulfurization wastewater.
Summary of the invention
Technical problem to be solved in the utility model is to provide and a kind of energy-conservation, simple carries out dense to desulfurization wastewater
The device of contracting
This utility model solves the technical scheme of desulfurization wastewater concentration and comprises the following steps:
S1, by desulfurization wastewater collect to pre-washing case.
S2, pre-wash before the desulfurization wastewater pre-washing in case is delivered to desulfurizing tower by pump flue pre-wash shower,
Or newly-built pre-wash shower.
S3, desulfurization wastewater fall in pre-washing shower, and before desulfurizing tower, the dustless high-temperature flue gas in flue gives up with desulfurization
Water carries out heat exchange, and partial desulfurization waste water becomes steam, enters desulfurizing tower, and the drop of desulfurization wastewater still falls within and pre-washes collection
Device, subsequently into pre-washing melt pit.
S4, pre-wash the desulfurization wastewater of melt pit and enter back into and pre-wash case.
Pre-wash desulfurization wastewater in case by pre-washing pump and beat 5 to 80 times that flow is desulfurization wastewater yield of circulation, in advance
After the desulfurization wastewater that wash spray pipe sprays and cleaner unit, the desulfurization of big flow is given up by the dustless high-temperature flue gas before desulfurizing tower
Water carry out heat exchange evaporation desulfurization wastewater is concentrated, can be concentrated into the former desulfurization wastewater water yield 1/10th or 20/
One.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
The each component names of labelling in accompanying drawing:
Before 1-desulfurizing tower 2-desulfurizing tower, flue 3-pre-washes shower 4-and pre-washes collection device 5-and pre-wash
Melt pit 6-pre-washes pump 7-and pre-washes case 8-desulfurization wastewater
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is described further, but embodiment of the present utility model
It is not limited to this.
As it is shown in figure 1, the device that a kind of desulfurization wastewater concentrates, comprise the following steps in using:
S1, desulfurization wastewater 8 is collected to pre-washing case 7.
S2, pre-wash before the desulfurization wastewater pre-washed in case 7 is delivered to desulfurizing tower by pump 6 flue pre-washes shower
3, or newly-built pre-wash shower 3.
S3, desulfurization wastewater fall in pre-washing shower 3, 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, enters desulfurizing tower 1, and the drop of desulfurization wastewater still falls within and pre-washes
Collection device 4, subsequently into pre-washing melt pit 5.
S4, pre-wash the desulfurization wastewater of melt pit 5 and enter back into and pre-wash case 7.
Pre-wash desulfurization wastewater in case by pre-washing pump and beat 5 to 80 times that flow is desulfurization wastewater yield of circulation, in advance
After the desulfurization wastewater that wash spray pipe sprays and cleaner unit, the desulfurization of big flow is given up by the dustless high-temperature flue gas before desulfurizing tower
Water carry out heat exchange evaporation desulfurization wastewater is concentrated, can be concentrated into the former desulfurization wastewater water yield 1/10th or 20/
One.
The yield assuming a certain power plant desulfurization waste water is 15 tphs, then the desulfurization wastewater in washer box is by pre-washing pump
The flow playing circulation is 75 to 1200 tphs, and the amount being concentrated into last desulfurization wastewater is about 1.5 tons or 0.75 tph.
