Steam stripping system for removing low-content vinyl chloride in PPVC latex

The invention discloses a steam stripping system for removing low-content vinyl chloride in PPVC latex, and relates to the technical field of devices for removing vinyl chloride in PPVC latex. The falling film pipes are arranged on the sieve plates, so that the contact area of latex and steam is increased, the latex directly falls to the next layer of falling film sieve plate from the falling film pipes, a weir plate is omitted, the flowing distance of the latex is obviously shortened, the demulsification phenomenon caused by long-time high temperature of the latex is prevented, the number of the sieve plates in the stripping tower is reduced, and the occupied space is small; the lower end of the falling film tube is connected with a drainage tube, so that latex is prevented from adhering to the sieve plate, large PPVC resin particles in the latex are prevented from depositing on the sieve plate and blocking sieve holes and a filter, and the industrial continuous production requirement is met; the residual qu
