Possible replacement of tank reactor,wide application,evenly distributed,high heat transfer efficiency

Technology introduction

Circulation reactor is a complete mixing flow reactor,it's a plug flow reactor as for millisecond reaction,since it can transfer heat immediately and decrease the concentration of product ,it can be applied in the reaction of quick rate,large amount of heat output,high precision of temperature control.

wide application,evenly distributed,high heat transfer efficiency

Technical principle

The circulation reactor promotes the mass transfer process of gas-liquid or liquid-liquid two-phase through the rapid flow of materials. The fast-flowing circulating liquid (reaction raw material) or(inert medium) can dilute the reaction heat, and then the reaction heat is removed by heat exchanger.The circulation reactor is beneficial to keep the temperature  stable in the reaction system. Macroscopically, the circulation reactor is a fully mixed flow reactor. For millisecond-level reactions, it's a  plug flow reactor, which the can the heat of reaction can be removed immediately and the concentration of reaction products is reduced. 

Technical advantages

The circulation reactor is a complete mixed flow reactor that can be applied in fast reaction speed, large heat output,high accuracy of temperature control.The reactor consists of enhanced mixing part, enhanced heat transfer part and a conveying part. DODGEN circulation reactor has many advantages,for example, wide applicability, evenly dispersion and high heat transfer efficiency, which makes it suitable for most of the working conditions that are difficult to solve in tank reactions.
