Accompanying drawing illustrates:
If Fig. 1 is structure of the present utility model and process flow diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings further illustrate use this new device produce high-purity phosphorus oxychloride most preferred embodiment particular content:
1. by be arranged at the dosing pump between Phosphorous chloride. storage tank 1 and chemical reaction kettle 4 and pipeline 7 will formula ratio Phosphorous chloride. measure after squeeze into chemical reaction kettle 4 after and seal；Oxygen pressure in oxygen storage tank 2 is maintained at 0.5Mpa, decompressor outlet pressure is 0.3Mpa, oxygen in oxygen storage tank 2 under the effect of decompressor by the first pipeline 8 being arranged between oxygen storage tank 2 and oxygen surge tank 3, enter oxygen surge tank 3, buffered after become flowing stable oxygen.
null2. start the agitating device in chemical reaction kettle 4 and start stirring，Oxygen in oxygen surge tank 3 is sent into chemical reaction kettle 4 by the second pipe 9 being arranged between oxygen surge tank 3 and chemical reaction kettle 4 simultaneously，Send oxygen amount ascending by the Valve controlling being arranged on second pipe 9，Oxygen and Phosphorous chloride. is allowed to react at chemical reaction kettle 4，After in still, pressure and temperature rises，It is gradually increased oxygen flow，Start the little temperature constantly of 4-5 at logical oxygen and be raised to 75 DEG C，And remain at 75-80 DEG C，Must not exceed set point of temperature，If well-defined reaction temp declines，At this moment oxygen flow will be increased，If temperature is increased beyond 80 DEG C，Oxygen-supply quantity should be gradually decreased to keep temperature all the time at 75-80 DEG C，Logical oxygen is stopped after reacting 6-8 hour，Phosphorus oxychloride crude product is obtained after being cooled to room temperature.
3. by phosphorus oxychloride crude product by be arranged at the centrifugal pump between chemical reaction kettle 4 and refining kettle 6 and pipeline 10 send into refining kettle 6 after stir, by the 3rd pipeline 11 that is arranged between steam generator 5 and refining kettle 6, steam sent into refining kettle 6, by being arranged at the Valve controlling steam flow on the 3rd pipeline 11, in making refining kettle 6, pressure must not exceed 4kpa, temperature must not exceed 130 DEG C, stirring reaction stopped supplying gas and stirring after 2-3 hour, the high-purity phosphorus oxychloride of finished product is obtained after being cooled to room temperature, the high-purity phosphorus oxychloride of finished product is by product outlet 12 discharging being arranged on refining kettle 6.
