Problems solved by technology
However, due to repeated cutting of the polymer molecular chain, the chain is broken, and the solution viscosity is reduced; at the same time, the swollen particles block the screen or the orifice plate, which cannot meet the requirements of polymer dispensing on offshore platforms.

The invention discloses a bipolar device used for accelerating dissolution of swelling particles of polymers and provided with cleaners. The device is characterized by comprising the cleaners, a stretching unit and a liquid storage cavity, wherein the cleaners fixed on a transmission shaft are arranged above the stretching unit and comprise a plurality of impeller blades; the stretching unit comprises an upper fixed fluted disc, a moving fluted disc, a lower fixed fluted disc, the transmission shaft and a bearing block; the upper fixed fluted disc, the moving fluted disc and the lower fixed fluted disc are arranged below the cleaners in sequence and are provided with a plurality of through holes; the surfaces, close to the moving fluted disc, of the upper and lower fixed fluted discs adopt short tooth structures which uniformly occlude with short tooth structures on the two surfaces of the moving fluted disc; the moving fluted disc is fixed on the transmission shaft; the transmission shaft is connected with a belt wheel via the bearing block and the liquid storage cavity; and the bearing block is fixed on the liquid storage cavity. The device is simple to install, occupies a small floor area, is light in weight, has high handling capacity, can accelerate polymer dissolution and has the function of interior cleaning.
Description
technical field [0001] The invention provides a forced stretching instant dissolving device for accelerating partial hydrolysis of polyacrylamide polymers, in particular to a bipolar accelerated dissolving device for polymer swelling particles with a cleaner. Background technique [0002] Polymer flooding, as one of the important methods to enhance oil recovery in oilfield development, has been widely used in onshore oilfields at home and abroad. Due to the lack of fresh water resources in offshore oilfields, the injected water has high salinity and high content of calcium and magnesium ions. Traditional partially hydrolyzed polyacrylamide has insufficient salt resistance and low viscosity, which is far from meeting the requirements of offshore oil fields. Due to the small number of hydrophobic groups on the main chain of the hydrophobic association polymer, the solution has the characteristics of a reversible three-dimensional network structure, good shear thinning and inj...
