Description
Technical field
The utility model relates to a kind of particulate filter, is specifically related to a kind of gas-liquid and mechanically combining and stirs the high polymer-bearing waste-water filter in backwash oil field.
Background technology
Along with deepening continuously and the application of tertiary oil recovery technology of oil field development, the prolongation of oilfield injection time, the residual polymerization substrate concentration in polymer-bearing waste-water raises gradually, have even up to 400 mg/L, and kept certain k value.Compare with conventional water drive sewage, existence due to residual polymer, the polymer-bearing waste-water viscosity raises, in water, the emulsion stability of oil droplet and solid suspension significantly strengthens, and makes water-oil separating and oil-containing intractability strengthen, the viscosity that the Produced Liquid aqueous phase keeps and the oil that comprises, be trapped in filter, nubbin after backwash accumulates over a long period, and is cause filtrate to harden and regenerate difficult principal element.
The effective regeneration of rear filtrate of how realizing hardening is the key point of high polymer-bearing waste-water filtering technique.Conventional backwash, the ball piece that the filtrate sheet surface layer is formed is difficult to broken, the greasy dirt impurity of filter material surface can not effectively be removed, drop into all after dates of next normal drainage, localised load increases, and impurity can sink to inside from the surface, and pelletizing increases gradually, and extending in the depth of cracking closure of filtrate, until whole filter failure.Thereby cause that filtrate is contaminated, the effluent quality variation.
Summary of the invention
In order to overcome only by conventional backwash filtrate difficulty and the poor deficiency of regeneration effect, the utility model provides a kind of gas-liquid and mechanically combining to stir the high polymer-bearing waste-water filter in backwash oil field, use favorable regeneration effect after this filter filtrate backwash, filter tank filter cycle is long, within the identical backwash time, can save 30～40% backwash water consumption.
The technical solution of the utility model is: this gas-liquid and mechanically combining stir the high polymer-bearing waste-water filter in backwash oil field and comprise filtering tank, stirring system and lower distribute water and air system, be provided with filtrate in filtering tank, described filtrate below is provided with lower distribute water and air system, lower distribute water and air system bottom surface is communicated with into the water air inlet pipe, the water inlet air inlet pipe extends to outside filtering tank, and filtering tank upper cover place is provided with stirring system and upper water distribution system.
The utlity model has following beneficial effect: using this filter is that stirring system and novel lower water distribution system are installed in filtering tank, the oil field is high contain poly-filter work filter cycle after, when carrying out backwash, at first start stirring system, with the filtrate top layer due to sump oil and the coalescent filtrate duricrust that hardens that forms of various impurity by after the fragmentation of dentation paddle, pass into air by novel lower distribute water and air system again and carry out the filtrate air purge, carry out at last the filter tank washing.Stirring makes the filtrate that hardens be able to fragmentation, is easy to regeneration; Air purge makes the frictional force between filtering material particle strengthen, and both have accelerated impurity and removal of pollutants speed on filtrate at the stack of effect, have not only shortened the time of water backwash, have also reduced the backwash water consumption simultaneously.Therefore, gas-liquid and mechanically combining stir the high polymer-bearing waste-water filter in backwash oil field, can adapt to the needs of oilfield polymer flooding tertiary oil recovery technology fully, realize the efficient rapid regeneration of filtrate.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of stirring system in Fig. 1;
Accompanying drawing 3 is structural representations of distribute water and air system in Fig. 1.
In figure 1, total header; 2, branched pipe; 3, the distribute water and air hole, the 4-cutting seam sieve tube, the upper water distribution system of 5-, the 6-motor, the 7-stirring system, the 8-cycloidal planetary gear speed reducer, the 9-shaft, 10-stirs tingia, 11-filtering tank, 12-filtrate, 13-locator, distribute water and air system under 14-, the 15-air inlet pipe of intaking.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in figure, this gas-liquid and mechanically combining stir the high polymer-bearing waste-water filter in backwash oil field and comprise filtering tank 11, stirring system 7 and lower distribute water and air system 14, be provided with filtrate 12 in filtering tank 11, described filtrate 12 belows are provided with lower distribute water and air system 14, lower distribute water and air system 14 bottom surfaces are communicated with into water air inlet pipe 15, water inlet air inlet pipe 15 extends to outside filtering tank 11, and filtering tank 11 upper cover places are provided with stirring system 7 and upper water distribution system 5.
Described lower distribute water and air system 14 comprises total header 1, and total header 1 both sides separation seal respectively are communicated with branched pipe 2, is distributed with distribute water and air hole 3 on branched pipe 2 walls, and branched pipe 2 outer wall covers have cutting seam sieve tube 4.
Have the distribute water and air hole 3 of φ 9～12mm on the branched pipe 2 of DN65～100, the gap of cutting seam sieve tube 4 is 2mm.How much deciding according to size and the back washing strength of filter tank diameter of the bore of branched pipe, the distribute water and air aperture that distributes on it and quantity, uniform distribution can be carried out to gas and the water of backwash in the distribute water and air hole of the φ 9～12mm that distributes on branched pipe when guaranteeing air water backwash intensity.
Described stirring system 7 comprises motor 6, cycloidal planetary gear speed reducer 8, motor 6, cycloidal planetary gear speed reducer 8 are arranged on filtering tank 11 upper cover tops, and the distribution power of drive motors is determined by the relevant parameters such as gear ratio of filter tank diameter, the size that stirs the tingia diameter, reductor.Cycloidal planetary gear speed reducer 8 is connected with by shaft 9 and stirs tingia 10, stirs the height of tingia 10 and can decide according to the height that filtering tank is loaded filtrate, and its rotating speed is decided by the concrete operations situation; It stirs tingia 10 and is positioned at 50～100mm place, filtering layer surface.Shaft 9 ends are equipped with locator 13.
When filter tank carries out backwash, first start stirring system 7, utilize 10 pairs of the stirring tingias imbed under the filtrate top layer filter material layer that hardens to carry out break process; Then first utilize novel lower distribute water and air system 14 to carry out the air backwash, bubble is when passing filter material layer, increase frictional force between filtrate and the perturbation action of filtrate deep layer, caused the collision friction that filtering material particle is violent, made impurity and pollutant on filtrate easily be peeled off removal; Recycle novel lower distribute water and air system 14 and carry out the water backwash, the loose filtering layer in backwash water top makes filtrate be suspended state, and the expansion of backwash water and backwash air superposes mutually, makes the dirt and the impurity that adhere on filtrate fully be peeled off removal.After the water backwash continued for some time, the whole backwash process of filter finished.
Gas-liquid and mechanically combining stir the backwash mode of the high polymer-bearing waste-water filter in backwash oil field, filtrate are stirred and dynamic hydraulic combined is counter combines.Its outstanding advantages is: not only the media regeneration performance is good, and backwash effect is good, and has shortened for 1/3rd filtrate backwash time, saves 30～40% backwash water consumptions, thereby has greatly improved the service efficiency of filtering tank.
