Description
Technical field
The present invention relates to chemical devices technical field, is filled more particularly, to a kind of new logical oxygen for being used to produce phosphorus trichloride
Put.
Background technology
POCl3 is the non-halogen fire-retardant for plastic of production and plasticizer as a kind of important chemical products（Such as tricresyl phosphate
Second fat）, agricultural chemical insecticide（Such as Spanon）, herbicide（Such as Acetochlor, quinoline and spirit）Primary raw material.
The logical oxygen device of production POCl3 at present, oxidation reaction, industry are directly carried out using oxygen is passed through in POCl3
It is inside to lead to oxygen reaction using in oxygen-supplying tube insertion phosphorus trichloride, is that reaction is insufficient, and draw into certain dead angle, largely to be not anti-
The oxygen answered is excessive, influences environment, in addition, can not fully react, there is an outflow of residual volume, the phosphorus trichloride in phosphorus trichloride compared with
Height, influence product purity.
The content of the invention
To overcome above mentioned problem, the present invention adopts the following technical scheme that：
A kind of new logical oxygen device for being used to produce phosphorus trichloride, including oxygen-supplying tube and main stills for air blowing, oxygen-supplying tube are sequentially connected production
Product feeding mouth and oxygen distributor, oxygen distributor are arranged on the bottom of main stills for air blowing, the inside center position of the main stills for air blowing
Agitating device is installed, the inwall on right side is provided with oxymeter scale, and main stills for air blowing top is provided with discharging opening, and discharging opening passes through pipe
Road is connected with secondary stills for air blowing.
The oxygen-supplying tube is provided with venting valve.
Divide hole provided with 400 circles in the oxygen distributor.
The agitating device is stirred using two-piece type.
The main stills for air blowing and secondary stills for air blowing use identical two.
It is an advantage of the invention that：Working time is short, process stabilization, and reaction is fully complete, securely and reliably, saves the energy, drop
Low oxygen consumption, reduces environmental pollution, and the device corrosion resistance is extremely strong, is advantageous to operating efficiency of keeping the safety in production and improve.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
As shown in figure 1, a kind of new logical oxygen device for being used to produce phosphorus trichloride, including oxygen-supplying tube 1 and main stills for air blowing 4,
Oxygen-supplying tube 1 is sequentially connected product feeding mouth 2 and oxygen distributor 3, and oxygen distributor 3 is arranged on the bottom of main stills for air blowing 4, described
The inner hub location of main stills for air blowing 4 is provided with agitating device 5, and the inwall on right side is provided with oxymeter scale 6, on main stills for air blowing 4
Portion is provided with discharging opening 7, and discharging opening 7 is connected by pipeline with secondary stills for air blowing 8.
The oxygen-supplying tube 1 is provided with venting valve 9.
Divide hole provided with 400 circles in the oxygen distributor 3.
The agitating device 5 is stirred using two-piece type.
The main stills for air blowing 4 and secondary stills for air blowing 8 use identical two.
The course of work is as follows：
In specific production process, oxygen enters oxygen distributor 3 by oxygen-supplying tube 1, by 400 circles point of oxygen distributor 3
Hole, which evenly distributes, is fully reacted, and eliminates dead angle；Oxygen is advanced to become owner of stills for air blowing 4, the agitating device 5 in main reaction kettle 4
Stirring reaction, the oxygen content after stirring were shown on oxygen gauge table 6, and the unreacted oxygen in part enters back into secondary stills for air blowing
8 are further continued for reacting.
