Background Polymer latices have been widely used in paints, adhesives, papermaking aids, leather and textile aids, etc., and polymer latices have been mainly obtained by emulsion polymerization. Because the monomer conversion rate during polymerization cannot reach 100%, part of unreacted monomers remain in the latex, generally 0.5% -1.0%, so that the product has peculiar smell, and the residual monomers volatilize during the use of the product, thereby causing environmental pollution and also endangering the health of users. The Chinese patent with publication number CN204073475U discloses a device for removing residual monomers from a copolymer resin emulsion, which has the problems that the emulsion is unstable and demulsified in the polymerization process, the material transfer process, the monomer removal process and the like, and condensed particles are easy to block a material transfer valve and a pipeline. In particular, under the stirring effect in the monomer removing kettle, more condensate is adhered to the stirring shaft and the kettle wall, manual cleaning is needed when the condensate in the kettle is cleaned, the replacement time before the kettle is put into operation is long, and the cleaning operation labor intensity is high.
