Force the bottom that described second pipe one end connects the other end and flash tank reboiler with flash tank bottom discharging opening
Circulating pump connects.
The Lauryl Alcohol ester conveyance conduit conveying end connects with second pipe, on the Lauryl Alcohol ester conveyance conduit
Provided with the first delivery pump and the first air valve.
Further, the flash tank reboiler top is provided with steam input pipe road, and bottom is provided with condensed water elimination pipeline；
The steam input pipe road is provided with the second air valve, and the condensed water elimination pipeline is provided with the 3rd air valve.
Further, it is also connected between flash tank bottom discharging opening and Lauryl Alcohol ester conveyance conduit on second pipe
There is buffering to change pipeline, buffering pipe is sequentially provided with the 4th air valve, the second delivery pump and the 5th air valve along conveying direction.
Further, the gas-phase transport pipeline end connects with rectifying column.
The utility model has the advantage of：
1）Flash tank of the present utility model adds a flash tank reboiler, crude product Lauryl Alcohol ester is introduced into flash distillation
Gasify in tank reboiler, remove impurity of the part in preamble process, into flash tank Lauryl Alcohol ester further gas
Change enters rectifying column, impurity is rested in flash tank the quality that ensure that product；And boiled again by flash tank and flash tank
The setting of device enables to the sodium methacrylate in material to rest in flash tank, effectively prevent sodium methacrylate in subsequent technique
In influence to product quality, reduce the decomposition of Lauryl Alcohol ester；The utility model is provided with flash tank, and Lauryl Alcohol ester passes through
Lauryl Alcohol ester gas-liquid separation is significantly reduced the energy consumption of rectifying column by flash tank.
2）The utility model is provided with buffering pipe, and when pressure is excessive in one side second pipe, open 4th air valve is by delaying
Liquid is discharged to reduce the pressure in pipeline in washing pipe road, and on the other hand, the waste liquid containing impurity of flash tank bottom can pass through
Second pipe and buffering pipe discharge.
3）The utility model can be reduced the load of equipment by the setting of flash tank reboiler and flash tank, reduce
The appearance and size and size of equipment, convenient and installation and the arrangement of maintenance and production scene.
