Abstract

The invention relates to a continuous hydrolysis kettle converted from a furfural intermittent hydrolysis kettle. An intermittent pressure preheating feeding device, a material level monitoring device, an intermittent deslagging amount and time control device and a computer control system for continuously discharging furfural are added to complete the converting process of the furfural hydrolysis kettle from intermittent to continuity.

Description

technical field [0001] The invention relates to a method of changing the current domestic fixed intermittent production hydrolysis kettle into a continuous hydrolysis kettle to achieve the goals of energy saving, emission reduction and production increase. Background technique [0002] At present, the furfural hydrolysis kettles in China are fixed intermittent production hydrolysis kettles, that is, a kettle of raw materials is installed, and the raw materials are fixed in the kettle. After steaming for 3 to 4 hours, the furfural gas produced is discharged to the next channel. The process is decondensed, and the remaining waste furfural slag is ejected into the atmosphere outside the kettle by several kilograms of exhaust gas in the kettle. After the hydrolysis kettle is emptied, the next kettle is loaded with new raw materials, and then the next kettle is produced, and so on. Foreign countries use a ball pot like popcorn. The whole pot is rotating, and the raw materials ins...
