Device used for accelerating dissolution of swelling particles of polymers and provided with fast dissolving rings and water seepage structures

Abstract

The invention discloses a device used for accelerating dissolution of swelling particles of polymers and provided with fast dissolving rings and water seepage structures. The device is characterized by comprising cleaners, a stretching unit and a liquid storage cavity, wherein the cleaners fixed on a transmission shaft are arranged above the stretching unit; 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 upper fixed fluted disc, the moving fluted disc and the lower fixed fluted disc are formed by connecting a plurality of groups of concentric tooth rings with different diameters; a plurality of water seepage channels are arranged inside the upper and lower fixed fluted discs and are communicated with a plurality of nozzles on short tooth structures; the water seepage channels are connected with an external connecting water tube; the moving fluted disc is fixed on the transmission shaft; and the liquid storage cavity is provided with a liquid inlet and a liquid outlet. The device is simple to install, occupies a small floor area, is light in weight, has high handling capacity, accelerates 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 an accelerated polymer swelling particle dissolving device with an instant dissolving ring and a water seepage structure. 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 str...

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.
