Butadiene feeding system

The utility model relates to a butadiene feeding system has one section feed passageway and two-stage process feed passageway that the back reaction cauldron let in the butadiene, sets up the centrifugal pump at one section feed passageway, and it is big that the centrifugal pump has a transmission capacity, the fast characteristics of fluid for the butadiene that gets into the centrifugal pump has great speed, mixs the material in the agitated reactor, makes material mixing even, set up the measuring pump at two-stage process feed passageway, flow that the measuring pump can the accurate control, the stability and the accuracy nature of technology are guaranteed to the volume of letting in of the later butadiene of two-stage process feed in accurate control carboxylic styrene butadiene latex's the production technology or two-stage process feed therefore for butadiene feeding system can adapt to present carboxylic styrene butadiene latex production technology well, and just can realize automatic feed through control centrifugal pump and measuring pump
