The production device mainly comprises reaction kettles (D101 and D102), storage tanks (F101 and F102), pumps (J101 and J102), a granulator (L101), a separator (L102), a blower (L103), a dryer (L104), and a pulverizer (L105), wherein the granulator (L101) is respectively connected with the reaction kettle (D101) and thereaction kettle (D102), the separator (L102) is respectively connected with the reaction kettle (D102) and the blower (L103), and the reaction kettle (D101) has a nominal volume of 600-700 L.

Description

technical field [0001] The invention relates to a compound synthesis device, in particular to a production device of sulfomethylated polyacrylamide. Background technique [0002] Sulfomethylated polyacrylamide is an anionic polymer with high relative molecular weight, easily soluble in water, and its aqueous solution is weakly alkaline. Used as a drilling fluid treatment agent, it has a good ability to increase viscosity and adjust flow patterns, and has strong resistance to temperature and salt. It can maintain the viscosity of drilling fluid under harsh conditions such as high temperature, high salt, and high calcium and magnesium ions. Good fluid loss control performance. However, this product is not suitable for direct use. It should be mixed with 0.1% to 1.0% glue before use, and then slowly added to the drilling fluid. The amount added is generally 0.05% to 0.2%. Most of the existing production devices are relatively complicated, and the pros and cons of sulfomethyla...
