Abstract

The invention belongs to the technical field of dissolving of polymers, and particularly relates to a supergravity device for rapidly dissolving water-soluble polymers, which solves the problems of long curing time, excessive curing tanks, low production efficiency and the like in the existing industrialized preparation process. The supergravity device comprises two stages or more than two stages of dissolving systems from top to bottom; each dissolving system comprises a static distributer, a dynamic distributer, a rotor and a diversion structure; and the rotors of the dissolving systems are coaxially arranged on a shaft which is connected to power. The supergravity device has the beneficial effects of small size, high dissolving capacity, short dissolving time and low operating expense.

Description

technical field [0001] The invention belongs to the technical field of polymer dissolution, and in particular relates to a supergravity device for rapidly dissolving water-soluble polymers. Background technique [0002] In the tertiary oil recovery process of petroleum, in order to increase the oil recovery rate, the anionic-polyacrylamide mother liquor is often used as the oil displacement agent, and the preparation technology of the polymer mother liquor is one of the key links. In the preparation of polymer mother liquor, due to the slow dissolution process of high molecular polymers, it often needs to go through pre-dispersion-swelling-dissolution (curing) and other processes. Process preparation process, the bottleneck that restricts the preparation capacity is the aging time and the number of aging tanks. If the preparation capacity is 500m 3 / h configuration station, need 110m 3 There are 22 curing tanks, and the curing time needs 2~3h. That is, the main problems ...
