Abstract
The utility model relates to a device for producing phosphorus oxychloride. The device comprises a reaction kettle (6) and an oxygen pipe (7), wherein the oxygen pipe (7) penetrates into the four-fifth position of the inside of the reaction kettle (6), a gas phase pipe (8) is arranged at the top of the reaction kettle (6), and a discharge outlet (4) is formed in the bottom of the reaction kettle (6). The device is characterized by further comprising a mixed reactor (5) mounted at the top end of the reaction kettle (6). The device can circularly enable raw materials of incompletely reacted oxygen and phosphorus trichloride to perform repeated mixed reaction, so that the reaction efficiency is improved, and the consumption of the oxygen raw materials can be reduced by above 20%.
Description
Technical field
The utility model relates to a kind of production equipment of phosphorus oxychloride, is specifically related to a mixing reactor is installed on the reactor of production phosphorus oxychloride, makes phosphorus trichloride more complete with reacting of oxygen.
Background technology
Phosphorus oxychloride, as a kind of important Chemicals, is the main raw material of the non-halogen fire-retardant for plastic of production and softening agent (as triethyl phosphate), agricultural chemical insecticide (as chlordimeform), weedicide (as acetochlor, quizalofop).
What phosphorus oxychloride production was both at home and abroad mainly taked at present is the phosphorus trichloride direct oxidation method, and reaction equation is 2PC1
3+ O
2=2POC1
3.Oxygen is directly passed in liquid phosphorus trichloride with pipeline, and oxidation generates POC1
3.This technological reaction mild condition, be easy to control, and is current domestic and international most popular operational path.But there are 2 problems in this technique in actual production: the one, and raw material oxygen is in reaction process, and the single assimilation effect is not good, and unreacted oxygen, with tail gas emptying, causes raw material consumption high; The 2nd, reaction time is long, because oxygen absorption efficiency is low, causes and must lead to for a long time oxygen and just can reach reaction end, and production efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of reaction unit of phosphorus oxychloride, one reaction mixer is installed on the reactor of production phosphorus oxychloride, by unreacted, raw material oxygen and raw material phosphorus trichloride carry out the repetition hybrid reaction completely, constantly repeat this process, until all raw material phosphorus trichloride and oxygen reaction are complete.
The utility model is to realize like this above-mentioned purpose:
A kind of production equipment of phosphorus oxychloride, comprise reactor and oxygen-supplying tube, and wherein oxygen-supplying tube gos deep into 4/5 place in reactor, reactor arranges the gas phase pipe on top, Polycondensation Reactor and Esterification Reactor arranges discharge port, and this phosphorus oxychloride production equipment also comprises mixing reactor, and mixing reactor is installed on the reactor top.
Described this mixing reactor rushes pump efficiency according to water and should design, and is the duct type mixed reactor, and the top of mixing reactor arranges opening for feed, and bottom is discharge port, and side is installed into tracheae, and feed pipe inserts internal mixer, is deeper than the inlet pipe mouth of pipe.
The discharge nozzle of described reactor is connected with the opening for feed of mixing reactor by recycle pump.
Described gas phase pipe connects the inlet pipe of mixing reactor.
The utility model has the advantage of: capable of circulation unreacted raw material oxygen and raw material phosphorus trichloride are carried out to the repetition hybrid reaction, improve reaction efficiency, reduce the consumption of the raw material oxygen more than 20%.
The accompanying drawing explanation
The structural representation of the production equipment that Fig. 1 is phosphorus oxychloride.
The structural representation that Fig. 2 is mixing reactor.
Embodiment
A kind of production equipment of phosphorus oxychloride, comprise reactor 6 and oxygen-supplying tube 7, wherein oxygen-supplying tube 7 gos deep into 4/5 place in reactor 6, reactor arranges gas phase pipe 8 on 6 tops, 6 ends of reactor, arrange discharge port 4, it is characterized in that: this phosphorus oxychloride production equipment also comprises mixing reactor 5, and mixing reactor is installed on reactor 6 tops.
Described mixing reactor 5 rushes pump efficiency according to water and should design, and is the duct type mixed reactor, and the top of described mixing reactor 5 arranges opening for feed 1, bottom is discharge port 4, side is installed into tracheae 2, and feed pipe 3 inserts internal mixer, is deeper than inlet pipe 2 mouths of pipe.
The discharge nozzle 4 of described reactor 6 is connected with the opening for feed 1 of mixing reactor 5 by recycle pump 9.
Described gas phase pipe 8 connects the inlet pipe 2 of mixing reactor 5.
The principle of work of phosphorus oxychloride production equipment:
After oxygen enters reactor by oxygen-supplying tube, small part is directly reacted with phosphorus trichloride and is generated phosphorus oxychloride.Most of oxygen escapes into reactor top.Reaction solution carries out outer circulation by recycle pump, from reaction mixer top opening for feed enters, from the bottom discharge port, get back in reactor again, in this process, due to Venturi effect, by the unreacted oxygen in reactor top by gas phase pipe sucting reaction mixing tank, with in dropping process with phosphorus trichloride again hybrid concurrency give birth to and react the generation phosphorus oxychloride.Constantly repeat this process, until all raw material phosphorus trichlorides all generate phosphorus oxychloride with oxygen reaction.
