Above body.
Further, the condensation reflux unit includes steam pipe, condenser, drain tank, oil water separator and return duct,
The condenser is connected to by steam pipe at the top of tank body, and condenser is connected by pipeline with drain tank, and drain tank passes through pipeline
It is connected with oil water separator, oil water separator is by return duct with being connected at the top of tank body.
Further, the oil water separator, which is also installed, is connected with drainpipe and blow-off pipe, and the return duct is connected to oil
Separator top, drainpipe are inserted into bottom, drain pipe port less than reflux nozzle, blow-off pipe connection by oil water separator top
In oil water separator bottom.
Further, it is provided with evacuation port at the top of the drain tank.
Preferably, the tank inner surface spraying polytetrafluorethylecoatings coatings.
Preferably, the agitating paddle surface spraying polytetrafluorethylecoatings coatings.
The substantive distinguishing features of the utility model and progress are：
The reaction kettle of the application available for the organic oxidizing reaction system using hydrogen peroxide as oxidant, has the following advantages：
（1）Agitating paddle is driven using the variable-frequency motor of adjustable speed, effectively improves reaction speed.Stirring at low speed, which feeds intake, to be conducive to
Agitating paddle is utmostly protected to be damaged caused by being collided from undissolved solid material, reaction process high-speed stirred makes reactant
The fully dispersed mixing of two phase materials in system improves reaction rate.
（2）By the design of condensation reflux unit, the material loss in reaction process is effectively reduced.Raw material in reaction process
Volatilization can cause to be lost, the raw material for making volatilization by condenser is condensed, then by oil water separator by raw material and moisture
After being separated, raw material is again introduced into tank body reaction, moisture discharge.
（3）In tank inner surface, agitating paddle surface spraying polytetrafluorethylecoatings coatings, auxiliary material loss is reduced, improves target production
Object conversion ratio extends the service life of reaction kettle.Polytetrafluoroethylene (PTFE) is to be currently known the extremely stable macromolecule material of chemical property
Material, will not be prolonged the service life in this reaction system by material corrosion.It is applied in carbon steel reaction kettle internal spray polytetrafluoroethylene (PTFE)
Layer can not only reduce auxiliary material catalytic decomposition loss, and the impurity introduced by side reaction is greatly reduced, and improve target production
The conversion ratio of object facilitates the separating-purifying in later stage.
