Liquids and gases through spray, in the process of dirty guide shell and upper reaches water conservancy diversion separator, because gas, liquid fully mix contact, mix the dead band so can eliminate basically, simultaneously, volatile component in the liquid phase (mainly being byproduct) migrates into gas phase and is moved out of reactor, and required heat is provided by the heat(ing) coil on the guide shell 4.
2. the two circulations of gas-liquid: when circulating pump 9 operations, form the liquid phase closed circuit, simultaneously, during injector 12 work,
Wherein high velocity jet liquid forms low pressure and causes the gas phase closed circuit, totally forms the gas-liquid double circulation loop.
For the device of gas-liquid reaction, its reaction tower is the little taper tower of diameter, and the time of staying of the gas-liquid mixture of high velocity jet in tower is shorter, a large amount of gas of carrying under one's arms easily, and the liquid phase that therefore circulates keeps higher gas holdup.Can be with liquid phase (containing dispersed gas phase) loop as main reaction loop (as annular-pipe reactor), as the endless tube catalytic reactor, the gas phase loop is as separating part comprising filling fixed bde catalyst; Also can be with reaction tower as main reaction region, the liquid phase closed circuit is auxilliary reaction zone, the gas phase loop is as separating part.Form gas-liquid mixture during injector work, great gas-liquid phase-contact surface can be provided, help gas one liquid mass transfer.
