a kind of raw material storage tank that contains cyclopentadiene for carbon five separation, comprise inlet point, discharging opening, it is characterized in that, in tank body, be provided with at least three arc baffle plates of list, it is semicircle that the arcuate edge of single arc baffle plate becomes, the another side of single arc baffle plate is straight shape limit, arcuate edge size and the spherical storage tank tank body inner circle consistent size of single arc baffle plate, with tank body welding, be integral, the direction that single arc baffle plate arranges is directly in ground, from base, count, the arcuate edge height dimension of single arc baffle plate is 30%～70% of tank body inner circle diameter dimension, single arc baffle plate is provided with at least one balance hole, the operating temperature of storage tank is normal temperature, and operation pressure is 0.1MPa, tank body, inlet point, the material of discharging opening and single arc baffle plate is Q-345B.
In tank body, be provided with two bouble-bow shape baffle plates, be provided with the baffle plate that two tops are straightsided shape, the inner circle consistent size of described its arcuate edge size of bouble-bow shape baffle plate and tank body, be integral with tank body welding; Described top is the arc size in base of baffle plate of straightsided shape and the inner circle consistent size of tank body, with tank body welding, is integral.
Each baffle plate is provided with at least one balance hole.
Between tank body, baffle plate, be connected with pole, when medium ground flowed, pole can prevent from causing the swing of baffle plate.
Compared with prior art, the beneficial effect that the utlity model has is: storage tank is spherical container, logistics enters from bottom, the volume of spherical tank guarantees that the material storing time, at 3～10 days, arranges baffle plate in tank body, overcome that material is taken a shortcut and the back-mixing problem during Flow of Goods and Materials, can improve the cyclopentadiene conversion ratio, reduce the concentration that enters hot dipolymer reactor cyclopentadiene, reduce the isoprene loss, reduce the wasting of resources.
