Quartz filter 2 is connect through feed pipe 30 with horizontal 3 pipeline of water washing tank；The horizontal water washing tank 3 is additionally provided with moisturizing
Pipe 31 is used for horizontal 3 make-up water source of water washing tank；It is additionally provided with discharge nozzle 32 on the horizontal water washing tank 3, for raw to MTBE
It produces device and conveys material.
The lower end of the horizontal water washing tank 3 be provided with circulation water pot 33, the circulation water pot 33 through centrifugal pump 40 with it is described
Water inlet pipe 10 be connected by pipeline.
The circulation water pot 33 passes through and is also parallel with auxiliary centrifugal pump 41 between the water inlet pipe 10.
The horizontal water washing tank 3 is horizontally disposed, and the feed pipe 30, discharge nozzle 32 are respectively arranged at 3 liang of horizontal water washing tank
End, the discharge nozzle 32 access horizontal water washing tank 3 from upper surface.
Cross-line 5 is also parallel between the adjustable mixer 1 and the feed pipe 30.
Sample tap and row's leaching mouth are additionally provided on the horizontal water washing tank 3；Liquid level is additionally provided on the horizontal water washing tank 3
Automatic Measuring Instruments and pressure instrumentation etc..The ratio between the quartz filter 2 and the swept volume of horizontal water washing tank 3 are 1:
5~7, in the present embodiment, the swept volume of quartz filter 2 and horizontal water washing tank 3 is respectively 50 cubes of 10 sum of cubes.
The workflow of the water washing device for extending MTBE catalyst life includes:
Liquefied petroleum gas is pressurized to 1Mpa from storage tank delivery pump, is delivered to through oil liquefied gas feed pipe 11 adjustable
