Abstract

The invention relates to a reactor for liquid-solid two-phase continuous reaction and on-line separation. The reactor is divided into an upper part and a lower part. The upper part of the reactor is a turn-back flow continuous reactor; and the lower part of the reactor is an on-line separator. A rotating shaft running from top to bottom is disposed in a reactor barrel body; multiple levels of dynamic flow deflectors and static flow deflectors are installed alternatively to form a reaction liquid baffling channel together; the dynamic flow deflectors are provided with stirring blades; the on-line separator comprises a filter screen, a cone-shaped helix, a filtrate tank, a circulating filtrate outlet and a filter cake outlet; and the reaction liquid enters the reactor, is baffled continuously in a plug flow form under the effect of self-gravity, and is mixed on the dynamic flow deflectors until the reaction is finished. The reactor realizes organic coupling of reaction and separation; the dynamic and static flow deflectors and the stirring blades on the dynamic flow deflectors are in cooperation with one another to realize the plug flow reaction and thorough mixing of the reaction liquid; and on-line separation and removal of products effectively reduce conversion of a heat sensitive product, and are beneficial to movement of a balanced reaction system toward a product direction, thereby increasing yield of the product.

Description

technical field [0001] The invention relates to an on-line separation liquid-solid two-phase reactor suitable for continuous operation in the chemical production process, in particular to a reactor used in chemical processes such as hydrothermal, crystallization, and impurity removal, and belongs to the technical field of chemical equipment. Background technique [0002] In chemical production, there is a type of liquid-solid reaction that not only needs to ensure sufficient residence time of the reaction materials, avoid back mixing to cause a wide distribution of the residence time of the reaction liquid, and the product is in a metastable state, but also avoid system pressure and temperature changes that may cause the product to Phase changes. If the multi-stage reaction kettle series hydrothermal method is used to prepare highly dispersed magnesium hydroxide, due to the influence of hydrothermal time distribution, the particle size distribution of magnesium hydroxide wil...
