Production system for phosphorylation reaction

Abstract

The invention discloses a production system for a phosphorylation reaction. The system comprises a phosphorylation reaction kettle. An operation platform is arranged on the upper portion of the phosphorylation reaction kettle, and a P2O5 feeding chamber is built on the operation platform. An air conditioner and an air dryer are installed in the P2O5 feeding chamber of the production system for the phosphorylation reaction, the temperature and the relative humidity during feeding can be controlled, and accordingly the situation that P2O5 absorbs moisture and cakes is effectively prevented. A vibrating machine is installed on a feeding inlet of the phosphorylation reaction kettle and can effectively control the feeding speed. A spiral helical ribbon agitator is adopted in the phosphorylation reaction kettle so that stirring can be uniform and sufficient. A temperature control device is arranged in a jacket of the phosphorylation reaction kettle and can effectively control the temperature in the phosphorylation reaction kettle. A circulating device is disposed outside the phosphorylation reaction kettle, reaction materials can circulate inside and outside the phosphorylation reaction kettle, so that stirring is more uniform, and the reaction is more sufficient.

Description

technical field [0001] The invention relates to the field of phosphorylation reactions, in particular to a production system for phosphorylation reactions. Background technique [0002] When carrying out the phosphorylation reaction, the reaction system in the prior art has the following defects: (1) the prior art usually artificially mixes P 2 o 5 Exposure to room temperature air and temperature conditions for feeding, at this time P 2 o 5 It is very easy to absorb moisture and agglomerate, and the speed of manual feeding is uneven, resulting in great temperature fluctuations in the reactor, and the agglomerated P 2 o 5 Can produce high temperature and make it coke when contacting with reactant in reactor; (2) adopt anchor stirrer to stir in the reactor in the prior art, its shortcoming is that stirring is insufficient and uniform; (3) prior art Cooling water and steam heating can be passed into the jacket of the reactor in the reactor, but the temperature control devi...

[0002] When carrying out the phosphorylation reaction, the reaction system in the prior art has the following defects: (1) the prior art usually artificially mixes P 2 o 5 Exposure to room temperature air and temperature conditions for feeding, at this time P 2 o 5 It is very easy to absorb moisture and agglomerate, and the speed of manual feeding is uneven, resulting in great temperature fluctuations in the reactor, and the agglomerated P 2 o 5 Can produce high temperature and make it coke when contacting with reactant in reactor; (2) adopt anchor stirrer to stir in the reactor in the prior art, its shortcoming is that stirring is insufficient and uniform; (3) prior art Cooling water and steam heating can be passed into the jacket of the reactor in the reactor, but the temperature control device is not provided, which causes the temperature in the reactor to change greatly, and the stability of the reactant is relatively poor; (4) the reactor in the prior art There is no external circulation device, and there is no filter on the circulation device. The lack of circulation device will lead to insufficient and uniform stirring in the reactor. Without a filter, there will be more impurities in the reactants and reactants that have not reacted. The quality is not stable enough
