[0002] Polyacrylamide is a linear high molecular polymer with good flocculation properties. It is widely used in various industries. Its molecular chain contains a certain number of polar genes that can adsorb solid particles suspended in water, bridge the particles to form large floccules, and thus reduce the frictional resistance between liquids to achieve the effects of thickening, bonding and film formation. In the application of polyacrylamide, foaming problems are also prone to occur.

[0003] After searching, the Chinese utility model patent with announcement number: CN213724976U discloses a defoaming device for diacetone acrylamide production. The above device pours the solution into a first defoaming container, and the first defoaming container is connected to the second defoaming container. There is a height difference between the discharge pipe and the feed pipe between the first defoaming container and the second defoaming container. The first defoaming container is pumped into the second defoaming container to defoam the solution in the defoamer. However, the solution in the first defoaming container is pumped into the second defoaming container, which increases the defoaming time and results in low defoaming efficiency.
