The factory produces high-purity acrylic acid. . Please help all the teachers if you need it! ! Thank you
The liquid phase and solid phase are converted into each other in the tubes of the crystallizer.
The structure is similar to that of a tube heat exchanger. The principle is that the mother liquid is circulated and cooled, and a film is crystallized on the tube wall. After the circulation volume of the mother liquid is reduced to a certain amount, the heat source is switched to circulate for heating and sweating, so that the crystallized liquid film melts and flows down, and is switched to the finished product tank.
I also want to know if you can be more detailed.
