Description
Technical field
The present invention relates to the gas-liquid reaction apparatus in fields such as chemical industry, petrochemical industry, environment, pharmacy, light industry, it is good particularly to have a mass-transfer performance, and suction capacity is strong, has a kind of self-suction type inner circulation overweight field gas-liquid reactor of super gravity field.
Background technology
All relate generally to gas liquid reaction in many fields such as chemical industry, petrochemical industry, environment, pharmacy, light industrys, conventional gas-liquid reactor comprises: gas is dispersed in bubbling column reactor in the liquid phase, stirs bubbling tank reactor and plate-type reactor with bubble shape, liquid is dispersed in spraying, injection and Wen's reactor etc. in the gas phase with droplet-like, the packed tower reactor that liquid contacts with gas phase with membranaceous motion and falling film reactor etc.In recent years, novel reactors such as Self-Priming Gas-Liquid Reactor, circulation flow reactor, rotating packed bed reactor have appearred.
In a lot of occasions, when requiring in reactor, to handle big quantity of fluid, generally select bubble tower and stirring bubbling tank reactor for use.The air-flow of tank reactor commonly used carries out feed liquid with mechanical agitation and mixes and gas dispersion by compressor or the supply of other gas conveying machinery in certain container, reach the purpose of reaction.The air-flow that this mode is supplied all needs special plant equipment and corresponding fabricating yard, auxiliary equipment, power consumption and maintenance management, the material corrosion problem that also exists that has.Therefore, the mechanical agitation direct gas-liquid contanct equipment of introducing gas in operation process with reactor begins to be subject to people's attention without gas conveying machinery.Self-Priming Gas-Liquid Reactor has just appearred based on this problem.
