To achieve the above object, the utility model uses the following technical solution: one kind in purification media for separating
The separator of phosgene, including shell, case top are provided with into raw material liquid pipe and exhaust pipe, and housing bottom is provided with discharge
Pipe and inert gas anti-blowpipe, shell is interior to be disposed with ultraviolet lamp reaction tube along its axial direction.
Compared with the prior art, the utility model has the following beneficial effects:
1, this separator first decomposes the phosgene in purification media, after it is real by way of stripping to decomposition product
The process of existing vapor-liquid separation, achievees the purpose that separate the phosgene in purification media, be provided by ultraviolet lamp reaction tube
The condition that ultraviolet light is catalytically decomposed as phosgene is generated, the additional impurity such as active carbon will not be introduced, reduce purifying
Medium subsequent purification difficulty and process, and the temperature for carrying out decomposition reaction to phosgene in separator is only reacted by ultraviolet lamp
Heat radiation that pipe generates and separator exchange heat and can meet with the external world, reduce energy consumption；
2, it is carried out instead into shell by the inert gas with pressure in this separator by inert gas anti-blowpipe
It blows, drains the product after decomposing in shell quickly from exhaust pipe under the stripping of inert gas, shorten decomposition product
Residence time accelerates phosgene forward direction decomposition reaction rate, separates the phosgene impurity in purification media preferably,
Improve separating effect and efficiently.
