A section of water outlet and collecting bell mouth (2) and a section of water outlet pipe (12) are arranged in a water collecting area which is arranged in the barrel body (15) and is formed by the barrel body (15) and a left sealing head (1). The SP component coalescer (14), the section water outlet pipe (12) and two sections of modifying coalescing elements (9) are connected with a water inlet pipe. Two sections of modifying coalescing elements (9), two sections of oil collecting tanks (8), the liquid level detecting head (3), two sections of water outlet and collecting bell mouths (18) and two sections of water outlet pipes (11) are arranged in a coalescing area which is arranged in the barrel body (15) and is formed by the barrel body (15) and a right sealing head (10). A sludge flushing pipe is at the bottom of the barrel body (15), and a section of oil collecting groove (4) and two sections of oil collecting grooves (8) drain oil and are connected with an oil draining pipe (17).
Description
(1) technical field:
The utility model relates to the efficient oily water treatment settling separation device in oil field.
(2) background technology:
What adopt at present in the oil-contaminated water of oil field treatment process is that two-stage sedimentation, two-stage filtration reach middle and high pervious course injection water quality index.Two-stage oily water separation slurry tank in this technical process (coagulant precipitation jar and natural subsidence jar) particularly gathers the oily water separation slurry tank that drives with ternary composite driving, and equipment volume is huge, floor space is big, and effective residence time is long, and processing efficiency is low, complex process, construction investment is big.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem that exists in the background technology, and a kind of small-sized efficient oily water treatment settling separation device is provided.
The invention for solving the technical problem can reach by following technical solution: air supporting choosing discharges head, one section floating trough, level detection head, one section oil trap and SP assembly coalescer and is installed in the flotation area of forming with one section water outlet dividing plate and dividing plate in the cylindrical shell; Catchment hydraucone and one section rising pipe of one section water outlet is installed in the catchment area of forming with left end socket in the cylindrical shell; SP assembly coalescer, one section rising pipe and two sections modification coalescing elements link to each other with water inlet pipe; Catchment hydraucone and two sections rising pipes of two sections modification coalescing elements, two sections oil traps, level detection head, two sections water outlets are installed in the coalescent district that forms with right end socket in the cylindrical shell; The mud washpipe is in the cylindrical shell bottom, and one section oil trap oil extraction links to each other with oil exit pipe with two sections oil trap oil extractions.
By the efficient oily water treatment settling separation device that such scheme constitutes, be more suitable for the high efficiency separation of disposing polluted water in oil.This tripping device is a horizontal pressure vessel, and entire equipment has flotation, coalescent, sedimentation, isolating function, and the equipment of having realized is integrated, reduces the volume of settlement separate equipment, has improved treatment effect, thereby saves construction investment.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: the purpose of developing efficient oily water treatment settling separation device, select the advantage of oil eliminator to put together material filling type small-sized efficient coalescence degreaser and jet air float exactly, in conjunction with producing the problem that exists in the middle of the actual motion, add the SP assembly, develop out efficient oily water treatment settling separation device, make it be more suitable for the efficiently settlement separate of disposing polluted water in oil.This separate and subside device is a horizontal pressure vessel, and entire equipment has flotation, coalescent, sedimentation, isolating function, and the equipment of having realized is integrated, reduces the volume of settlement separate equipment, has improved treatment effect, thereby saves construction investment.
(4) description of drawings:
Accompanying drawing is this device cross-sectional schematic.
(5) embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
Shown in accompanying drawing, it is according to some member in the existing apparatus, air supporting choosing is discharged 3, one sections oil traps 4 of 6, one sections floating troughs 5, level detection and SP assembly coalescer 14 be installed in the flotation area that 15 li of cylindrical shells and one section water outlet baffle plate 13 and dividing plate 16 formed; Catchment hydraucone 2 and one section rising pipe 12 of one section water outlet is installed in the catchment area that 15 li of cylindrical shells and left end socket 1 formed; SP assembly coalescer 14, one section rising pipe 12 and two sections modification coalescing elements 9 link to each other with water inlet pipe; Catchment hydraucone 18 and two sections rising pipes 11 of 3, two sections water outlets of two sections modification coalescing elements 9, two sections oil traps 8, level detection is installed in the coalescent district that 15 li of cylindrical shells and right end socket 10 formed; The mud washpipe is in cylindrical shell 15 bottoms, and one section oil trap 4 oil extraction links to each other with oil exit pipe 17 with two sections oil trap 8 oil extractions.
It is by discharging the small bubbles that head discharges that this master puts main effect, will carry in flotation area and floatingly be removed to the water surface by discharging oil in water emulsion in the processed sewage and bigger particle oil droplet.After floating oil slick to the water surface reaches certain thickness, oil discharge outlet by one section oil trap 4 is discharged simplified by oil exit pipe, the water after the oil removing enters the buffer zone of being made up of one section water outlet baffle plate 13 and left end socket 1, catchment by one section water outlet hydraucone 2 that catchments, through SP assembly coalescer 14, enter modification coalescing element 9 by modification coalescing element water inlet pipe, sewage is by SP assembly coalescer 14 time, the further collision coalescence of not removing of little oil droplet in the water, enter modification coalescing element 9 then, again through the effect of modification coalescing element, reach further collision coalescence, after the oil-contg of coalescent collision reaches certain saturation degree, just by discharging in the modification coalescing element, by division board 16, floating in the coalescent district that cylindrical shell and right end socket 10 are formed to the water surface, reach certain thickness after, discharge cylindrical shell by the oil discharge outlet of two sections oil traps by oil exit pipe; Mud impurity in the coalescent deoiling process in the sewage, also sedimentation simultaneously and flotation are removed, and are deposited to the mud impurity of cylindrical shell bottom, discharge cylindrical shell by shore pipe, thereby reach the purpose of sewage purification.
