Multifunctional epoxypropane extraction device

Abstract

The invention provides a multifunctional epoxypropane extraction device. The device comprises a supporting base, a lifting tower, a liquid discharging pipe, a backflow pipe, an extraction tower, a first conveying pipe, a second conveying pipe, a rectifying tower, a third conveying pipe, a fourth conveying pipe, a fifth conveying pipe, a manhole cylinder, a spraying processing pipe frame structure, a movable adjusting maintenance plate frame structure and a switch sealing protection cover structure. The lifting tower is welded at the upper end of the supporting base; the liquid discharging pipe is welded at the middle part of the lower end of the lifting tower; the return pipe is welded on the right side of the lower end of the lifting tower; the extraction tower is mounted at the upper end of the lifting tower through bolts and nuts; the first conveying pipe is welded at the lower part of the left side in the extraction tower; and the second conveying pipe is welded above the right side in the extraction tower. The device has the beneficial effects that through the arrangement of the spraying processing pipe frame structure, extraction liquid can be sprayed out dispersedly and is distributed in the extraction tower for extraction work.

Description

technical field [0001] The invention belongs to the technical field of chemical extraction, and in particular relates to a multifunctional propylene oxide extraction device. Background technique [0002] Propylene oxide is mainly used to produce polyether polyols, propylene glycol and various nonionic surfactants, etc. It is an important basic chemical raw material. During the processing of propylene oxide, it will be processed through an extraction tower, thereby increasing epoxy The purity of propane is better for other processing. [0003] However, the existing propylene oxide extraction device still has the problems that the extracted liquid cannot flow countercurrently and work uniformly during extraction, it is not convenient to work at the switch maintenance department and it is not convenient to adjust the use of space for internal maintenance. [0004] Therefore, it is very necessary to invent a kind of extraction device of multifunctional propylene oxide. Conten...
