Abstract

The invention discloses a solvent recovery device of an isoprene rubber device, which belongs to the field of chemical equipment and comprises a gas storage tank communicated with a spray tower. The spray tower is communicated with an adsorption tower, the spray tower comprises a spray tower shell, and a spray device is arranged in the spray tower shell; three groups of rotational flow devices are sequentially arranged in the spray tower shell from top to bottom in the vertical direction; a rotational flow plate rotating shaft is arranged in the spray tower shell; the rotational flow device comprises a rotational flow plate, the rotational flow plate is fixedly arranged on a rotational flow plate rotating shaft, the rotational flow plate can rotate along with the rotational flow plate rotating shaft, and the solvent recovery device of the isoprene rubber device can improve the recovery efficiency of hexane and increase the adsorption of VOCs, so that a better discharge effect is achieved.

Description

technical field [0001] The invention relates to a gas separation device, in particular to a solvent recovery device of an isoprene rubber device, belonging to the technical field of chemical equipment. Background technique [0002] In the production process of polyisoprene rubber, hexane process tail gas containing saturated water vapor is systematically discharged, and hexane is consumed more every day, which not only causes waste, but also pollutes the environment. With the stricter national environmental protection policy At the same time, in order to implement the national "Air Pollution Prevention and Control Action Plan" and adapt to the development trend of air pollutant emissions, the waste hexane will be recovered and treated. The original hexane recovery device cannot fully To achieve the purpose of VOCs emission standards and recovery of solvents. [0003] The prior art discloses the application number: CN201821384495.2, the patent application date: 20180827; the...
