Accompanying drawing explanation
Fig. 1 is the structure drawing of device that benzyl alcohol produces waste water extraction.
Detailed description of the invention
Describe specific implementation method of the present utility model below in conjunction with the accompanying drawings in detail:
As it can be seen, the device of the industrial wastewater of a kind of continuous extraction benzyl alcohol production includes transfer tank 1, crude product settling tank
3, extraction mixing kettle 5, extraction oil settling tank 6, extraction oil tank 7, benzyl ether rectifying column 8, benzyl ether finished pot 9 and crude product tank 10,
The bottom of described transfer tank 1 and middle part are connected with condenser 2 simultaneously, and condenser is provided with cooling water inlet 21 and coolant outlet
22, cool down hydromining phreatic water.
Condensator outlet is connected with the top of crude product settling tank 3, and the top of crude product settling tank is connected with crude product tank 10, bottom
Being connected with extraction mixing kettle 5 top, crude product settling tank 3 is provided with automatic flow actuator with the connection pipeline of extraction mixing kettle 5
31.Benzyl ether finished pot 9 is provided with automatic flow actuator 33 with the connection pipeline of extraction mixing kettle 5.
The bottom of benzyl ether finished pot 9 with extraction mixing kettle 5 top is connected, extraction mixing kettle 5 bottom discharge pipe and
The top of extraction oil settling tank 6 connects, and the discharge pipe bottom extraction mixing kettle 5 is provided with automatic flow actuator 32.Extraction
The top of oil settling tank is connected with extraction oil tank 7, and extraction oil pot bottom is connected with benzyl ether rectifying column 8, benzyl ether rectifying column
Bottom is connected with benzyl ether finished pot 9.
Material A from benzyl alcohol reaction initially enters transfer tank 1, and transfer tank 1 temperature of charge is at 70-80 degree.Transfer tank
Material enters crude product settling tank after entering a spiral lamina condenser 2 by transfering material pump P1, and the condensed water of condenser uses deep-well
Water.The temperature of charge of crude product settling tank is at 40-50 degree, and material is layered in crude product settling tank, and the lowest layered effect of temperature is the brightest
Aobvious upper strata is crude product oil phase, and lower floor is salt aqueous phase, and the content of the benzyl alcohol in saline is about 1.5%.
The oil phase on crude product settling tank upper strata is gone to crude product tank, the oil phase in crude product tank by the overfall overflow on the left side again
Rectification process.The saline of crude product settling tank lower floor by the high-order overfall continuously overflow on the right to extracting mixing kettle,
Benzyl ether in benzyl ether finished pot continuously enters extraction mixing kettle by P2 transfering material pump with certain flow velocity, saline and
The flow velocity of benzyl ether is controlled by automatic flow actuator, and saline and benzyl ether are uniformly mixed in mixing kettle, mix simultaneously
Close the material in still and continuously go to extraction oil settling tank, the material liquid in extraction mixing kettle from bottom by P3 transfering material pump
