Accompanying drawing explanation
Fig. 1 is the schematic diagram of the oil-contained waste water treatment device of prior art.
Fig. 2 is the schematic diagram of oil-contained waste water treatment device of the present invention.
Of the prior art 201010155198.2 equipment proposing a kind of preparing clean water by using oil field sewage, see Fig. 1, flashing tower system is primarily of sump pump 1, flashing tower 2, compressor 14, interchanger 15, throttling valve 16, vacuum pump 13, concentrated sewage lagoon 11 and clean water basin 12 form, it is characterized in that flashing tower 2 is set to vertical type cylinder shape, a condenser 6 is provided with at middle part on flashing tower, the import and export of condenser are stretched out from the middle part of upper cover, a round type orifice plate device 5 is provided with in the middle and upper part of flashing tower, circular ring type or row's formula spray thrower 4 is provided with at the middle part of flashing tower, spray thrower is connected with fluid inlet 3, spray thrower bottom is set to the sedimentation chamber 9 that non-flash of steam concentrates sewage, a sewage outlet 10 is provided with bottom flashing tower, in flashing tower upper cover bottom, all sides are provided with a vacuum orifice 7, a clear water output 8 is provided with in all sides of orifice plate device, sump pump outlet is connected with fluid inlet, compressor inlet is connected with condensator outlet, and compressor outlet is connected with the import of condenser by interchanger, throttling valve, and vacuum pump import is connected with vacuum orifice, clear water output is connected with clean water basin, and concentrated sewage outlet is connected with concentrated sewage lagoon.But in this technical scheme, there is following defect: 1, orifice plate device is circular flat plate structure, and distilled water is easily detained, impact effect, and orifice plate device upwards flows and can produce obstruction to flashed vapour; 2, distiller is positioned on orifice plate device, and the distilled water of generation may drop onto sedimentation chamber by the hole of orifice plate device, affects the collection of distilled water; 3, spray thrower sprays downwards, directly may spray sedimentation chamber, makes the flash distillation insufficient space of sewage, and spray thrower also affects the upwards transmission of flash gas.
Embodiments of the invention are the optimization to prior art, can overcome above-mentioned defect.See Fig. 2, oil-contained waste water treatment device provided by the invention, comprises sump pump 1, flashing tower 2, compressor 14, interchanger 15, throttling valve 16, vacuum pump 13, concentrated sewage lagoon 11 and clean water basin 13 and forms.Sump pump 1 is for by oily(waste)water suction flashing tower 2; Spray thrower 4, orifice plate device 5 and condenser 6 is disposed with from top to bottom in flashing tower 2, spray thrower 4 arranges spray header, sewage for being pumped by sump pump 1 to spray in flashing tower 2, condenser 6 is for being condensed into water of condensation by flash-off steam, and orifice plate device 5 is for being discharged to clean water basin by water of condensation; Vacuum pump 13 is for extracting noncondensable gas in tower from tower top vacuum orifice; Compressor 14 is for being compressed into high temperature and high pressure gas by the working medium in condenser 6; Interchanger 15, for high temperature and high pressure gas cooling is become cryogenic high pressure liquid, then through throttling valve 16 pressure regulation, then passes in the interchanger 6 in flashing tower 2; Concentrated sewage lagoon 11 is for collecting the sewage of non-flash distillation.
Orifice plate device 5 comprises end face, bottom surface and the side between upper end face and bottom surface, and described upper end face is circular, is provided with for the through hole by flash vapors in it; Described bottom surface is annular, and described annular interior diameter is greater than described round diameter, forms water of condensation runner between described bottom surface and flashing tower wall; Described side connects described arc of circle limit and described circular inside diameters, and described side becomes to be greater than the special angle of zero with horizontal plane, and this special angle can be set to about 45 degree.By the such setting to orifice plate device 5, water of condensation along the side flow of orifice plate device 5 to bottom, thus can improve the collecting effect of water of condensation.
