Multifunctional epoxypropane separation device

Abstract

The invention provides a multifunctional epoxypropane separation device which comprises an epoxypropane separation tower, an epoxypropane re-separation tower, a separation guide pipe, a first heat exchanger, a condensation pipe, a discharge pipe, a second heat exchanger, a backflow pipe, a drainage pipe with a valve, a discharge pipe and a liquid discharge pipe. One end of the separation guide pipe is in threaded connection with the outlet at the lower right side of the epoxypropane separation tower, and the other end is in threaded connection with the inlet at the lower left side of the first heat exchanger. Through the arrangement of the liquid inlet hopper, the flow guide box, the impurity filtering net, the machine cover, the stirring motor and the auger, stirring and filtering of an epoxypropane solution are facilitated, the separation effect is guaranteed, the epoxypropane solution is introduced into the flow guide box through the liquid inlet hopper, impurities are filtered through fastening of the impurity filtering net, and the stirring motor on the right portion of the machine cover drives the auger to rotate, the solution is stirred, and thus the filtering effect is ensured, and the separation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of organic matter separation, in particular to a multifunctional separation device for propylene oxide. Background technique [0002] Propylene oxide, also known as propylene oxide and methyl oxirane, is a very important organic compound raw material and the third largest propylene derivative after polypropylene and acrylonitrile. Propylene oxide is a colorless ether-like liquid with a low boiling point and is flammable. [0003] At present, the separation of propylene oxide device is widely used. [0004] However, the existing propylene oxide separation device still has the inability to filter the propylene oxide solution, which affects the separation effect. The odor gas generated during the separation is easy to pollute the environment, and it is not convenient to collect the separated propylene oxide and the discharged solution. It is not convenient to filter Drainage processing issues. [0005] There...
