Gas-liquid-solid multiphase reaction-separation synchronous reactor

Abstract

The invention relates to a gas-liquid-solid multiphase reaction-separation synchronous reactor comprising two parts which are a reaction system and a separation system. The reaction system comprises a bubbling gravity reaction tower. A gas raw material introducing port and a gas distributor are arranged on a lower part in the reaction tower. A plurality layers of alternative cooling coils are arranged in a gas-liquid separation zone at the upper part of the bubbling gravity reaction tower. Gravity sedimentation plates are arranged in a reaction zone at the middle-lower part of the bubbling gravity reaction tower. The separation system comprises two thermostatic sedimentation towers with a same structure and a same size. Pressure balance tubes are connected between the tops of the thermostatic sedimentation towers and the top of the bubbling gravity reaction tower. The reactor provided by the invention is applied in gas-liquid-solid multiphase reactions in which product specific gravities are higher than those of reactants and in which the products and the reactants are immiscible, such that synchronous chemical reaction and separation is realized. According to a traditional production mode, a multiphase substance is transferred to a separator through a pipe for separation. With the gas-liquid-solid multiphase reaction-separation synchronous reactor provided by the invention, reaction and solid product separation can be synchronized, and the traditional production mode is not needed.

Description

technical field [0001] The invention relates to a reaction separation synchronous reactor, in particular to a gas-liquid-solid multiphase reaction separation synchronous reactor. Background technique [0002] In chemical production, gas-liquid-solid multiphase reactions in which the specific gravity of the product is greater than the reactant and are incompatible with each other are often encountered. [0003] For this type of reaction, gases, liquids and solids exist in the reaction system simultaneously during the reaction. In the existing chemical production mode, the reactants and reaction products are distributed in the reaction zone naturally or forcibly (such as stirring) during the entire reaction period. After the reaction is over, the reactant and the reaction product are moved to a separator for separation. Since the existence of multi-phase substances in the system will affect the fluidity of the liquid in the production device, it cannot be continuously produc...

Problems solved by technology

The continuous process of insoluble products can be realized by adding solvents; however, the addition of solvents makes the chemical production process complicated, and also increases the corresponding equipment investment and energy consumption, material consumption and environmental pollution by solvents; another One option is to use interstitial operations to produce

In the above two schemes, the residence time of the reaction product in the reaction system will be increased, and under the reaction operating conditions, the reaction product will be decomposed or deeply reacted, resulting in a decrease in the selectivity and yield of the reaction product
