Beschreibung
Zusammenfassung:	The utility model provides an external heat exchange device for oximation reaction of phoxim, which belongs to the technical field of chemical engineering and comprises an oximation kettle, an external condenser, a compressor and an evaporative condenser. The external condenser, the compressor and the evaporative condenser are sequentially connected according to the flowing direction of a refrigerant to form an external refrigerating system, a liquid outlet of the evaporative condenser is communicated with a liquid inlet of the external condenser, and an air outlet of the external condenser is communicated with an air inlet of the compressor; a top cold charge inlet of the oximation kettle is communicated with a top cold charge outlet of the external condenser; a bottom discharging hole of the oximation kettle is communicated with a bottom feeding hole of the external condenser; a raw material inlet pipe is also arranged at the top of the oximation kettle, and a finished product discharge pipe is also arrange
