Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operating principle etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
As shown in Figure 1, for the structural representation of this vehicular well-flushing water recycling equipment, comprise basket filter 2, automatic pressure regulator 11, desander 5, tramp iron separator 6, air supporting flow tank 7, strainer 9, filtered water tank 91, sump oil case 92 and three-cylinder plunger pump 94, above-mentioned parts composition water circulation system, this circulating system is carried out purified treatment to the waste water of well-flushing after oil-field flooding and is recycled in oil well again.
Well-flushing waste water enters basket filter 2 from well mouth oil pipe external member 1, basket filter 2 Main Function is the solid removing larger particles, so that this vehicle-mounted well-flushing water recycling equipment work, pipeline between basket filter 2 and desander 5 is provided with automatic pressure regulator 11, flushing fluid pressure is reduced to below 1.0MPa, pipeline is also provided with pressure meter 3 and flow meter 31 simultaneously, play a part to monitor current, sand setting case 51 is provided with bottom desander 5, fine particle in desander 5 is all deposited in sand setting case 51 under gravity, sand setting case 51 discharges the grains of sand and fine particle thing by the sewage draining exit 52 that bottom is arranged.Tramp iron separator 6 is connected with desander 5, Main Function removes in water containing ferromagnetic suspension, tramp iron separator 6 is connected with air supporting settling tank 7 further, most of elaioleucite in main removal water, content gauge 71 and air dissolved pump 72 are installed on air supporting settling tank 7 simultaneously, play monitoring liquid level respectively and accelerate deposition efficiency, sewage draining exit 73 is provided with bottom air supporting settling tank 7, some deposit seeds of main discharge, in air supporting settling tank 7, the fluid of precipitation is flowed in sump oil case 92 by pipeline and collects, be drawn into oil export 93 by self priming pump 95 again and release recycling, one end of air supporting settling tank 7 is connected with safety valve 4 by pipeline, prevent pressure in air supporting settling tank 7 excessive.Strainer 9 is connected with air supporting settling tank 7, is accelerated the flowing of current between the two by tubing pump 8, and strainer 9 is its medium and small oil droplet and suspension of removing further, and the clear water after process flows in filtered water tank 91 and stores.
