| titleOfInvention | The manufacture method of residual monomer removal device and polyvinyl alcohol resin |
| abstract | The invention provides and a kind of the bias current of organic solvent gas, the delay of polymer fluid and efficiently can remove the residual monomer removal device of unreacted monomer and the manufacture method of polyvinyl alcohol resin from polymer fluid not easily occur on tower tray.In residual monomer removal device (1), the polymer fluid (4) imported from polymerization tank (3) is made to contact with in the demonomerization operation removing the monomer polymer fluid (4) with organic solvent gas such as methyl alcohol, be used in tower body the residual monomer removal device (1) being equipped with multilayer valve tray (2), described valve tray (2) possesses the multiple gas blowing units only at the direction opening vertical with the circulating direction of polymer fluid (4) or the circulating direction downstream side opening towards polymer fluid. |
