Solid-liquid reaction device

Abstract

The invention provides a solid-liquid reaction device, which comprises a conical reactor, a base, a gas bubble generating device, a gas source, a compressor and a gas filter, wherein the top of the reactor is closed and is sequentially connected to the gas filter, the compressor, the gas source and the gas bubble generating device through pipelines. According to the invention, by arranging the gasbubble generating device at the bottom of the reactor, the solid reactants or catalysts deposited at the bottom of the reactor move to the upper portion of the reactor under the impact force of the micro gas bubbles, so that the solid completely and uniformly contacts the liquid; and the solid-liquid reaction device has characteristics of cyclic utilization of gas, uniform solid-liquid mixing, high reaction efficiency and energy conservation.

Description

technical field [0001] The invention relates to the technical field of chemical reaction devices, in particular to a solid-liquid reaction device. Background technique [0002] With the wide application of polymer materials in chemical industry, it is usually necessary to react solid polymer materials with chemical liquids. In the traditional liquid-solid reaction, the liquid is the reaction liquid or organic solvent, and the solid is the reactant or catalyst particles. In the prior art, there are the following technical problems: [0003] 1. The solid-liquid reaction device has a single way of stirring solid-liquid mixing. During the reaction process, the reactants and solids are not in contact and mixed enough, the reaction is not complete, and the reaction rate is low; [0004] 2. The generated reactant is attached to the solid surface, so that the internal reactant is isolated from the liquid, resulting in insufficient reaction; [0005] 3. The specific gravity of sol...

Problems solved by technology

[0003] 1. The solid-liquid reaction device has a single way of stirring solid-liquid mixing. During the reaction process, the reactants and solids are not in contact and mixed enough, the reaction is not complete, and the reaction rate is low;

[0004] 2. The generated reactant is attached to the solid surface, so that the internal reactant is isolated from the liquid, resulting in insufficient reaction;

[0005] 3. The specific gravity of the solid is much greater than that of the liquid, which is easy to settle and not easy to be stirred evenly. Traditional chemical reactor stirring cannot fully mix the materials
