Abstract
The utility model relates to a tank for removing oil and sand from sewerage, which is used in the sewage treatment technology in oil fields. The utility model comprises a tank body, a liquid inlet pipe, an oil collecting inlet and a water outlet pipe. A liquid inlet cavity, a filling cavity, a sloping plate separating cavity and a water storage cavity are sequentially arranged from the inner part at the left end of the tank body to the inner part at the right end. The sewerage from the liquid inlet pipe is sequentially processed in the methods of allocation, coalescence, sedimentation and separation through the four cavities, so that the oily content of the discharged sewerage is reduced to be less than 30 mg/L from 160 mg/L and the sand removing percentage is more than 90%. Every tank for removing oil and sand from sewerage can recover the oil of more than 2700 tons, and the economic benefit in one year is more than 1, 350, 000 yuan.
Description
The utility model relates to the sewage degrease desanding jar that adopts in the treatment process for sewage in oil field.
In recent years, " three adopt engineering " adopted for improving oil recovery factor in China part oil field, injected a large amount of high molecular polymers as oil-displacing agent to underground, the also corresponding oil-displacing agent composition (average polymer content reaches more than the 50mg/L in the recovered water at present) that contains in the extraction liquid, certain variation has taken place in the character of water, has brought difficulty to sewage disposal.Cause in the defeated outward sewage of sewage plant about oleaginousness average out to 50mg/L, about suspension content average out to 20mg/L, exceeded set quota (oil-containing≤30mg/L in the SY/T5329-94 standard respectively, 67% and 130% of suspension content≤10mg/L) has proposed new problem for the oil field sewage disposal.Sewage disposal device can not satisfy the production needs at present, can not fundamentally solve the above-mentioned technical barrier that runs in the disposing polluted water in oil.
The purpose of this utility model just is to provide a kind of disposing polluted water in oil sewage degrease desanding jar that the station is used.Crude oil in the sewage is removed, and recycled, save energy removes suspended substance in the sewage and sand, makes the defeated sewage of sewage works reach required standard outward, satisfies the field produces needs.
Above-mentioned purpose is realized by following technical proposals.
The utility model is made up of tank body, liquid-inlet pipe and rising pipe.Play right-hand member in tank body left end inside only inner, is provided with admission chamber, packing cavity, swash plate disengagement chamber and reservoir by preface;
The spherical cap center of admission chamber is provided with the elbow-shaped liquid-inlet pipe, and fluid inlet is towards spherical cap, and the admission chamber the other end is provided with by the waved plate group of stent support, is provided with sewage draining exit in the admission chamber bottom;
The packing cavity two ends are provided with the filler barrier, and the right-hand member barrier is provided with baffle plate in two ends up and down, and the top of packing cavity is provided with receiving port or feeding port, and the bottom is provided with sewage draining exit or discharge gate, and the sewage draining exit place is provided with the dividing plate of ball;
The swash plate of swash plate disengagement chamber is made up of one group of declined board and one group of inclined board, two groups of supported of swash plates pursue preface is separated by, each autoparallel being fixed in the swash plate disengagement chamber, the middle part is provided with an oil outlet on the swash plate disengagement chamber, right-hand member top is provided with a feeding port, swash plate disengagement chamber left end bottom and middle and lower part are provided with sand removing hole, are provided with the sand clean out pipe of band nozzle on sand removing hole both sides, middle and lower part;
Be provided with towel font rising pipe at reservoir right-hand member spherical cap central part, the reservoir bottom is provided with sand removing hole.
According to the oilfield sewage station sewage degrease desanding jar that technique scheme is made, day output can reach 5000m
3, cooperate the efficient compound reinforcement of utilization HPAM chemical treatment, processing back sewage index is reached: oil-containing≤30mg/L, oil removal efficiency improves 20%, 2700 tons of annual every recyclable crude oil, year is created 1,350,000 yuan of economic benefits.Make the sewage with oil index reach company standard.
For the clear the technical program of expressing, be further elaborated below in conjunction with Figure of description 1,2,3,4.
Fig. 1 is the utility model one-piece construction cross-sectional schematic.
Fig. 2 is a waved plate group view profile among Fig. 1.
Fig. 3 is Fig. 1 median septum 26 structural representations.
Fig. 4 is sand clean out pipe 24 structural representations among Fig. 1.
Among the figure, the 1st, cylindrical shell, the 2nd, liquid-inlet pipe lacing wire, the 3rd, liquid-inlet pipe, the 4th, waved plate support, the 5th, waved plate group, the 6th, collection tube, the 7th, Ball-type packing barrier, the 8th, baffle plate, the 9th, Ball-type packing, the 10th, collection tube, the 11st, support, the 12nd, crossbeam, the 13rd, swash plate, the 14th, dividing plate, the 15th, feed port, the 16th, rising pipe support, the 17th, rising pipe, the 18th, rising pipe lacing wire, the 19th, manhole, the 20th, buttress, the 21st, sediment outflow pipe, the 22nd, water eliminator, the 23rd, sand clean out pipe, the 24th, water nozzle, the 25th, blow-off pipe, the 26th, ball dividing plate, the 27th, sewage draining exit.
The technological principle flow process of this device is:
The sewage that joint station is deviate from enters admission chamber by liquid-inlet pipe 3, sprays to the spherical cap of tank body 1 by fluid inlet, and liquid dispersion is opened, and the little oil droplet come-up of the part in the liquid accumulates in the top of admission chamber, flows into pipe networks from collection tube 6.Discharge from sewage draining exit 27 the assorted bottom that is deposited in admission chamber of part machine, and liquid is by waved plate group 5; enter the coalescent coarse of packing cavity, then by swash plate group 13 with the oil-sand water sepn, oil and suspended substance up; be advanced into reservoir under the sand, sewage is outer defeated by receiving water pipe 17 then.Sewage is in flow process, little oil droplet in the sewage is by waved plate group 4, Ball-type packing 9, swash plate group 13 surface adsorption, friction, gravity fractionation, make crude oil float over tank inner chamber top, by receiving port 10 with crude oil recovery, the assorted polymkeric substance that reaches of machine in the sewage makes the assorted bottom that is settled down to except that oil tank of its machine under the effect of the efficient compound of HPAM, sediment passes through sand clean out pipe 23 by clear water when effluxing, water nozzle 24 flushings, sediment effluxes by sediment outflow pipe 21.Handle through the preface of pursuing of admission chamber, packing cavity, swash plate disengagement chamber and reservoir from the sewage that water inlet pipe is come in, reached the company standard of wastewater disposition.
