Abstract

The invention discloses an epichlorohydrin saponification tower, and relates to the technical field of epichlorohydrin processing, the epichlorohydrin saponification tower comprises a saponification tower, the inner wall of a mixing box is provided with a stirring mechanism, the bottom of the mixing box is provided with nozzles which are distributed in a circumferential array, the outer wall of a supporting rib is provided with a tower tray, the inner wall of a rotary drum is provided with an adjusting mechanism, and the adjusting mechanism is provided with an adjusting mechanism. A driving mechanism is arranged at the bottom of the outer wall of the saponification tower, a flushing mechanism is mounted on one side of the saponification tower, and a scraping and washing mechanism is mounted on the outer wall of the rotary drum. When saponification is carried out, a second motor can be started to drive a screw to rotate clockwise, then a sleeve block is driven to slide upwards through rotation of the screw, and the far end of the circle center of a supporting rib inclines upwards through a connecting rod hinged to the screw, a short rod hinged to one end of the connecting rod and the supporting rib hinged to the outer wall of a rotary drum; and finally, the tower tray is funnel-shaped and can receive saponification reaction liquid, so that the residence time of the saponification reaction liquid at the bottom of the tower tray is prolonged, and the saponification effect is improved.

Description

technical field [0001] The invention relates to the technical field of epichlorohydrin processing, in particular to an epichlorohydrin saponification tower. Background technique [0002] Epichlorohydrin is an organic compound whose main purpose is to make epoxy resins. It is also a stabilizer and chemical intermediate for oxygen-containing substances. For purposes such as curing propylene-based rubber, the preparation of epichlorohydrin requires first saponification to obtain a crude product of epichlorohydrin. The equipment used in the saponification process is a saponification tower. In the prior art, the product generated during the saponification reaction of epichlorohydrin is long. The accumulation of time on the column plate is prone to fouling, which is difficult to clean, time-consuming and labor-intensive, and affects the subsequent saponification reaction and reduces the production efficiency of epichlorohydrin. [0003] In view of the above-mentioned problems, th...
