Board -like rectifying column piece -rate system of high -purity pentane

The utility model discloses a board -like rectifying column piece -rate system of high -purity pentane, package rubbing board formula rectifying column, condenser, pentane are kept in jar and the pentane storage tank, and upper portion is equipped with and prevents the liquid flooding device in the board -like rectifying column tower body, it has multilayer baffling board to constitute circuitousgaseous phase rising passway to distribute in the condenser, and countercurrent flow is carried out to pentane raw materials and pentane gaseous phase in the condenser. Compared with the prior art, the utility model has the advantages of it is following: the one of which after with pentane rectification high -temperature steam's waste heat transmit for the pentane raw materials, improve pentane raw material feed temperature, next structure of improving the condenser improves pentane contaminated gas phase effect, the third through setting up anti -overflowing plate and liquid flooding pipe, can prevent effectively tha
