Abstract
The utility model relates to a sand washing work equipment in oil field, e.g. a sand cleaning fluid processing vehicle, which comprises a loading vehicle chassis, a recovery oil tank, an air-floating settling box and a hydrocyclone are communicated and arranged on the loading vehicle chassis in turn. Air-floating settling box is divided into a plurality of communicated areas by partition to reduce flow rate of oil water, extend residence time and facilitate centralization of oil stain. An aerator is arranged in the air-floating settling box to oxygenate and aerate oil water, tiny bubbles are generated in the oil water, which is favorable to separating oil from oil water. With the advantages of high oil recovery rate and high desanding rate, the utility model saves a great quantity of water resource and can carry out sand washing work continuously to realize green work and clean production.
Description
Technical field
The utility model relates to a kind of Sand-washing in Oilfield implement, and promptly sand cleaning fluid is handled car.
Background technology
In prior art, when Sand-washing in Oilfield liquid processing car owner will be used for the Sand-washing in Oilfield operation, sand cleaning fluid is carried out oil, water, sand separation, reach that crude oil recovery, water circulation are used, the on-the-spot discharging of sand or discharge to the appointed place, pollute thereby reduce, the conserve water resource, the crude oil that reclaims in the sand cleaning fluid is offset part sand washing operating cost, and can carry out the open flow operation.Sand cleaning fluid is handled the car owner and will be made up of hydrocyclone, flow tank, recovery fuel tank, appearance gas tank, self priming centrifugal pump, liquid-way system, air-channel system, electrical system, pipe valve system, lorry loading chassis etc., its shortcoming is to be a big empty van body in the flow tank, and oil-water separation is poor.
The utility model content
The purpose of this utility model is to provide a kind of sand cleaning fluid that improves oil-water separation to handle car at above-mentioned deficiency.
Technical solution of the present utility model is: sand cleaning fluid is handled car and is comprised the load wagon chassis, arranges in turn to be communicated with on the load wagon chassis and reclaims fuel tank, flow tank, hydrocyclone.The flow tank inner-use clapboard is divided into the zone of a plurality of connections, reduces the flow velocity of profit, the lengthening holdup time, is convenient to greasy dirt and gathers.Be provided with aerator in certain zone, profit is carried out oxygenic aeration, produce micro-bubble in profit, the oil content that is more conducive in the profit is separated.
The utility model has the advantages that: 1, oil recovery rate height, remove the sand coarse aggregate ratio height, can carry out the sand washing operation continuously, realize green operation and cleaner production.2, put in sand water oil content other places, saves factory's great lot of water resources, and the crude oil of recovery has bigger economic benefit again.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is Fig. 1 schematic top plan view.
The specific embodiment
Referring to Fig. 1, sand cleaning fluid is handled car and is comprised load wagon chassis 1, arranges in turn to be communicated with on load wagon chassis 1 and reclaims fuel tank 2, air supporting flow tank 3, hydrocyclone 4.
Referring to Fig. 2, air supporting flow tank 3 inner-use clapboards 5 are divided into four zones, first area 6, second area 7, the 3rd zone 8 are the decanting zone, the 4th zone 9 is a clear water zone, in second area 7, be provided with three aerators 10, enter clear water zone clear water can directly be discharged in the tank of ground or in self priming centrifugal pump pumps into the ground tank.The zone that dividing plate 5 is divided into is not limited to above-mentioned a kind of, and according to the size of casing, the zone can be different, can select in a plurality of.The quantity of the placement of aerator 10, the zone of placement also are not limited to above-mentioned a kind of, can all place in each zone, or be chosen in placement in a certain zone, decide as required, are placed on second area in this example, place three, separate the best results of profit.
Dividing plate 5 is designed to wave plate shape, hinders flowing of each interior profit in zone, increases the time of staying, is convenient to greasy dirt and gathers.
The core technology that sand cleaning fluid is handled car is that degreasing technique falls in gentle the drifting along of eddy flow desanding technology.Hydrocyclone 4 makes sand cleaning fluid rotate strongly along the hydrocyclone inner chamber, the heavy particle is under the effect of centrifugal force and gravity, enter silt box along separator cone, fluid in the silt box is in flap valve enters air supporting flow tank 3, the silt particle particles settling is in silt box, in this process, the silt particle clearance is greater than 99.8%.The profit liquid of removing most silt particles enters in the air supporting flow tank 3, and aerator 10 makes the oil emulsion in the liquid and the major part of dispersed oil become oil slick under compressed-air actuated effect, flows in the oil tanks through oil collecting pipe 11.A small amount of silt particle and most suspended substances are deposited in the air supporting flow tank 3, can be discharged by the emptying manifold through backwash.By sand cleaning fluid is carried out oil, water, sand separation, reach that crude oil recovery, water circulation are used, the on-the-spot discharging of sand or discharge to the appointed place, to pollute thereby reduce, the conserve water resource reclaims the crude oil counteracting part sand washing operating cost in the sand cleaning fluid.
