Description
Technical field:
The utility model relates to fracturing outlet liquid treatment facility field, is specifically related to oil field compression fracture and returns discharge opeing treatment unit.
Background technology:
Inverted discharged pressing crack liquid has the crude oil on stratum to return discharge opeing discharge with stratafrac in the later stage that liquid spues successively, because stratum is grown and the difference of geologic framework, the outlet pressure of the water oil mixt of discharging is pulse type, flow is also unstable, time height time low, the fracturing outlet liquid complicated component ejected, particularly viscosity is very high, adds fracturing outlet liquid intractability.
Utility model content:
In order to solve the problem, the utility model proposes a kind of oil field compression fracture and returning discharge opeing treatment unit.
The technical solution of the utility model is: oil field compression fracture returns discharge opeing treatment unit, comprise water inlet pipe, water inlet pipe is communicated with bottom drains receptacle, water inlet pipe top has coagulant dosage pipe to be communicated with drains receptacle, air pump is separately had to stretch into drains receptacle by aerated conduit bottom drains receptacle, drains receptacle top is provided with scrapper conveyor, scrapper conveyor side is provided with oil reservoir, there is the import of pipeline communication boosting pump drains receptacle side bottom oil reservoir, boosting pump outlet conduit is communicated with flocculation tank import, flocculation tank outlet inclined plate sedimentation pond, the pump inlet of pipeline communication sludge reflux is had bottom inclined plate sedimentation pond, the import of sludge reflux pump outlet main cyclone separator, the outlet of main cyclone separator bottom is positioned at above flocculation tank, the overflow outlet auxiliary connection cyclone separator import of main cyclone separator, secondary cyclone separator outlet at bottom is positioned at above sludge concentrator.
The inlet pipes of flocculation tank is provided with drug feeding pipeline.
Flocculation tank is equipped with agitator.
The utility model has following beneficial effect: processing speed is fast, conventional flocculation reaction, sedimentation, filtration waits water purifying process flow process due to the sedimentation of throw out, the speed floated is slow, in addition the resistance of filtering medium causes solid-liquid separation to reach more than at least 2 hours consuming time of the limpid need of water quality, device adds coagulating agent in the drains receptacle stage, first fracturing outlet liquid breakdown of emulsion is made, under the effect of aeration, remove partial open return suspended substance in discharge opeing, favourable further process, device is due to the solid-liquid separating method of uniqueness, add special quartz sand as reaction medium, the settling time of the floc sedimentation in fracturing outlet liquid is shortened greatly, eliminate flocculate solids sedimentation, the time of floating and filtering, therefore, the treatment time of whole water just shortens greatly, system does not need back flushing, operates continuously, and treating processes does not need the residence time, because whole water treatment procedure is unresisted trickling formula, there is not the problem of the blocking that is hampered in current yet, device volume is little, treatment capacity is large, by the calculating to flocculation reaction time and volume flow, equipment de-sign specification is optimized to minimum, reduces floor space, can save a large amount of places and capital construction, maintenance and working cost, and water quality is also better.
Accompanying drawing illustrates:
Accompanying drawing 1 is schematic flow sheet of the present utility model.
1-water inlet pipe in figure, 2-drains receptacle, 3-scrapper conveyor, 4-oil reservoir, 5-air pump, 6-aerated conduit, 7-boosting pump, 8-flocculation tank, 9-agitator, 10-coagulant dosage pipe, 11-main cyclone separator, the secondary cyclone separator of 12-, 13-sludge concentrator, 14-inclined plate sedimentation pond, 15-sludge reflux pump.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, oil field compression fracture returns discharge opeing treatment unit, comprise water inlet pipe 1, water inlet pipe 1 is communicated with bottom drains receptacle 2, water inlet pipe 1 top has coagulant dosage pipe 10 to be communicated with drains receptacle 2, air pump 5 is separately had to stretch into drains receptacle 2 by aerated conduit 6 bottom drains receptacle 2, drains receptacle 2 top is provided with scrapper conveyor 3, scrapper conveyor 3 side is provided with oil reservoir 4, there is pipeline communication boosting pump 7 import drains receptacle 2 side bottom oil reservoir 4, boosting pump 7 outlet conduit is communicated with flocculation tank 8 import, flocculation tank 8 outlet inclined plate sedimentation pond 14, pipeline communication sludge reflux pump 15 import is had bottom inclined plate sedimentation pond 14, the import of sludge reflux pump 15 outlet main cyclone separator 11, main cyclone separator 11 outlet at bottom is positioned at above flocculation tank 8, overflow outlet auxiliary connection cyclone separator 12 import of main cyclone separator 11, secondary cyclone separator 12 outlet at bottom is positioned at above sludge concentrator 13.
The inlet pipes of flocculation tank 8 is provided with drug feeding pipeline.
Flocculation tank 8 is equipped with agitator 9.
Fracturing outlet liquid is by air pump aeration, concurrent fracturing returns in discharge opeing and adds coagulating agent, coagulating agent and fracturing outlet liquid fully mix the miniature flco of rear generation, the miniature flco of part is combined with micro bubbles and the crude oil in fracturing outlet liquid is carried into the water surface simultaneously, oil reservoir is entered by after the crude oil collection in fracturing outlet liquid by the scrapper conveyor of drains receptacle, the fracturing outlet liquid that part separating suspension contains miniature flco enters flocculation tank after boosting pump boosting, a certain amount of trickle quartz sand particle is added above flocculation tank, add flocculation agent simultaneously, the miniature floc sedimentation of the breakdown of emulsion in the fracturing outlet liquid of quartz sand particle after coagulating is combined, rely on the density of quartz sand large, under the effect of agitator, carry out bridging effect in conjunction with flocculation agent fast to form large floc sedimentation and enter inclined plate sedimentation pond, the mud being deposited in bottom enters main cyclone separator through sludge reflux pump, quartz sand large for density is entered coagulation reaction tank recycling from outlet at bottom by main cyclone separator, the mud separated enters secondary cyclone separator through the top overflow port of main cyclone separator, mud is separated and enters sludge concentrator and carry out concentration by secondary cyclone separator further, the upper outlet of clear water after process through inclined plate sedimentation pond flows out.
Device adds coagulating agent in the drains receptacle stage, first fracturing outlet liquid breakdown of emulsion is made, under the effect of aeration, remove partial open return suspended substance in discharge opeing, favourable further process, participate in process owing to having added quartz sand particle, accelerate the process of fracturing outlet liquid process, make mud-water separation be more prone to, quartz sand can be reused simultaneously, reduces fracturing outlet liquid processing cost, shorten the fracturing outlet liquid treatment time, decrease investment and take up an area.
