The exit of the spiral feeder is disposed on the upper port of the feed hopper whose lower part is connected to a diffusion cavity of the ejector via a switch, and the exit of the ejector is connected with the feed liquid ripening tank. The device has the advantages of being rational in designation, simple in structure, low in production cost.
Description
Technical field
The utility model belongs to raising oil recovery rate device, specially refers to a kind of device of directly dispersing polymer dry powder by hydraulic jet.
Background technology
In the tertiary oil recovery field in oilfield exploitation later stage, generally take polymer displacement of reservoir oil tech to improve oil recovery rate.In the polymer flooding ground installation, polymer dispersed is the main technique link of polymer formulation.For many years, polymer dispersed technology adopts the technological process that wind-force disperses always.To blow to the pigment mixing arrangement through the polymer dry powder of metering by wind-force, and carry out stirring and dissolving after water tentatively mixes, be transported to the slaking of slaking jar by induction system afterwards.The shortcoming of this process is: the one, by wind-force transferring polymer dry powder, increased the energy consumption of system; The 2nd, behind the pigment mixing arrangement, solution mixes even inadequately, must be delivered to the slaking of slaking jar by induction system then through stirring; The 3rd, the flow process of too many levels has caused the control system complexity, and occupation area of equipment is big, investment is big.A kind of hydraulic jet dispersing technology was disclosed in 2003---the polymer dry powder water jet dispersing and dissolving device (patent No.: 02255875.6), this technology has solved the problem that wind-force disperses power consumption, but still after polymer is by aqueous dispersion, need dissolving tank and induction system to be delivered to the slaking jar, link is many, the control system complexity, investment is high.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, provides that a kind of dispersion effect is good, the device of the simple directly dispersing polymer dry powder by hydraulic jet of technological process.
The device of directly dispersing polymer dry powder by hydraulic jet of the present utility model is made of dry powder storage tank, screw(-type) feeder, water supply system, hydraulic ejector and slaking jar.Wherein, water supply system pipeline has successively connected motor operated valve, electromagnetic flowmeter, the pressure meter core tube inlet to ejector, and the export pipeline of electromagnetic flowmeter has connected electromagnetic valve, and continued to enter the feeding funnel with the pipeline tangent line.The bottom of dry powder storage tank has been installed stuff level switch and bottom blanking switch, and has been connected to the inlet of screw(-type) feeder by the road, the outlet of screw(-type) feeder places the suitable for reading of feeding funnel, the bottom of feeding funnel is through the diffusion chamber of switch connection ejector, and the outlet of ejector connects feed liquid slaking jar.
The device of directly dispersing polymer dry powder by hydraulic jet of the present utility model is reasonable in design, simple in structure, cancel traditional polymer and disperseed stirring and dissolving and the defeated flow process of screw pump in the flow process outward, simplified polymer dispersed technology, save power consumption, equipment investment and operational and administrative expenses, realized full process automatization.
Description of drawings
Figure of description is the apparatus structure schematic diagram of directly dispersing polymer dry powder by hydraulic jet of the present utility model.
Embodiment
The device of directly dispersing polymer dry powder by hydraulic jet of the present utility model is made of dry powder storage tank 1, screw(-type) feeder 2, water supply system 3, hydraulic ejector 4 and slaking jar 5.Wherein, water supply system 3 pipeline has successively connected motor operated valve 5, electromagnetic flowmeter 6, the pressure meter 7 core tube inlet to ejector 4, and the export pipeline of electromagnetic flowmeter 6 has connected electromagnetic valve 8, and continued to enter feeding funnel 9 with the pipeline tangent line.The bottom of dry powder storage tank 1 has been installed stuff level switch 10 and bottom blanking switch 11, and has been connected to the inlet of screw(-type) feeder 2 by the road, the outlet of screw(-type) feeder 2 places the suitable for reading of feeding funnel 9, the bottom of feeding funnel 9 is through the diffusion chamber of switch 12 connection ejectors 4, and the outlet of ejector 4 connects feed liquid slaking jar 13.
The device of directly dispersing polymer dry powder by hydraulic jet of the present invention is to provide the polymer formulation water by water supply system, and current enter by pipeline and form eddy current in the ejector, forms to stablize vacuum; Open dry powder feeding funnel bottom switch, form the passage that polymer dry powder enters ejector; Open the electromagnetic valve of dry powder feeding funnel, current enter dry powder feeding funnel and form rotary water current, flushing feeding funnel inside; Calculate the polymer dry powder blanking velocity that is complementary with current discharge by computer system; Polymer dry powder is inhaled in the ejector diffusion chamber by dry powder feeding funnel; Water turbulence forms violent cutting stirring action to the polymer that sucks in the ejector, makes between the particle of polymer dry powder to be separated from each other, and the polymer dry powder particles is fully wetting by water, forms the pigment mixture, directly enters the slaking of slaking jar by pipeline again; The slaking jar is full, and computer system control dry powder storage tank quits work; The closed electromagnetic valve of dry powder feeding funnel, dry powder feeding funnel bottom switch cuts out; Water supply system quits work.
System abnormal conditions comprise as outlet conduit stop up, flow of inlet water lowly excessively causes forming in ejector when stablizing vacuum, no dry powder flows or hang down abnormal condition such as material level following time:
Dry powder feeding funnel bottom switch cuts out, and it is excessive to prevent from water to pass through the ejector charging aperture, and polymer dry powder blanking simultaneously and metering system are closed, the closed electromagnetic valve of dry powder feeding funnel, and water supply system is closed.
