Abstract

The invention relates to a move bed reactor, formed by screw reaction bed and lifter. Wherein, the screw reaction bed is formed by outer cylinder, inner cylinder, liquid inlet, material outlet, divert plate, screw reaction bed, and base; the lifter is formed by water tank, driven wheel water outlet, lifting hopper, chain, driving wheel, motor, speed reducer, and frame; the lifter and screw reaction bed share one chassis. The invention is used in solid-liquid neutralization; especially the solid is block material. The invention has simple structure without block.

Description

technical field [0001] The invention relates to a moving bed reactor, in particular to a moving bed used for neutralization reaction, belonging to the field of chemical equipment, in particular to a kind of equipment used for neutralization reaction in acidic water. Background technique [0002] Acid-base neutralization reaction is one of the common processes in chemical unit operation. The neutralization reaction is generally a liquid-liquid reaction or a liquid-solid acid-base reaction, and the reaction equipment used is: liquid-liquid reactions mostly use stirring equipment and static mixers, and when the solid phase is powder in the liquid-solid acid-base reaction, stirring equipment is generally used , cyclone or static mixer, when the solid phase is bulk material, neutralization tank, neutralization filter bed or neutralization filter are generally used. Some acid-base neutralization reaction products are prone to crusting and fouling, which is not conducive to the co...
