Description

Short flow process polymer dispersed device

Technical field:

The utility model relates to the used polymer dispersed device in oil recovery field, oil field, especially short flow process polymer dispersed device.

Background technology:

In the long-term exploitation in oil field, underground crude oil is not under the minimizing situation of section, in order to increase crude output, adopt polymer displacement of reservoir oil at present, improve oil production, polymer displacement of reservoir oil is polymer and water etc. to be mixed the back by concentration requirement inject undergroundly, and needs when mixing to mix after polymer and the aqueous dispersion.And the dispersal device that uses at present makes dispersibility descend because long flow path easily causes polymer aggregational agglomerating, be difficult to guarantee the concentration proportioning requirement, and exist that volume is big, complex structure, be not easy to the problem of keeping in repair and moving, influence oil displacement efficiency, be unfavorable for applying.

The utility model content:

In order to overcome existing dispersal device long flow path, dispersibility difference and baroque deficiency, the utility model provides a kind of short flow process polymer dispersed device, and this weak point flow process polymer dispersed device has the flow process weak point, dispersibility reaches characteristic of simple structure by force.

The utility model folding technical scheme is: this weak point flow process polymer dispersed device, comprise feed bin and chassis, fixedly feed bin and dispersion tank on the chassis of band roller, feed bin is built-in with the elevator bottom of top band return duct and tremie pipe, return duct and tremie pipe are respectively with feed bin and conical bottom is arranged and the dispersion tank taken out of between two parties mouthful communicates, dispersion tank upper end is built-in with the some shower nozzles that communicate with pipe and the ring pipe in the some holes of internal diameter band, pipe is connected with flow meter respectively successively with outlet, valve, pump and pump, valve, in the outlet correspondence be covered with umbrella shape disperse cap and by pipe with pump pipe and communicate, the intrinsic blower fan of top board inwall on the feed bin, blower fan communicates by tube and tube.

The beneficial effect that the utlity model has is: because short flow process polymer dispersed device is fixed with feed bin and dispersion tank on the chassis, feed bin is built-in with the elevator of band return duct and tremie pipe, return duct and tremie pipe communicate with feed bin and dispersion tank respectively, go up the shower nozzle that end plate has some holes, endless belt in the dispersion tank, correspondence is covered with the dispersion cap in taper outlet placed in the middle, polymer enters in the dispersion tank by elevator, the shower nozzle that passes through the dispersion tank upper end in free-falling process is with water and mixed with polymers, again by disperseing cap further to disperse, so just shortened flow process greatly, strengthen dispersibility, guaranteed the requirement of concentration proportioning, and volume is little and simple in structure, be convenient to maintenance, owing to be fixed with roller under the chassis, be convenient to move simultaneously, applicability is strong.
