Through mixing before water inflow and mixing during water outflow, the mixing efficiency of water and acid liquor is greatly improved, the final actual PH standard of water entering nanofiltration can be ensured, and adverse effects on nanofiltration can not be caused.
Therefore, the utility model has the advantages of can rapid mixing acidizing fluid and water ensure that the PH is stable, can not influence and receive and strain.
Further, the utility model discloses a lower part and the upper portion at ultrafiltration product water bucket set up inlet tube and outlet pipe respectively to make business turn over water mode become and advance to go up and go out down, make water and acidizing fluid stop more for a specified time in ultrafiltration product water bucket, make mixing between them more abundant and stable.
The aeration pipe is additionally arranged at the bottom of the ultrafiltration water producing barrel, and then the fan existing on site is used for supplying air to the aeration pipe, so that water in the ultrafiltration water producing barrel flows, and mixing is accelerated.
The rotating shaft driven by the driving motor is additionally arranged in the ultrafiltration water producing barrel, and the stirring rod is arranged on the rotating shaft, so that liquid can be stirred and mixed quickly; and set up spiral vortex pipe in puddler below to can play the effect of vortex, further accelerate mixing.
Through setting up level sensor, PH sensor, controller, a control valve, No. two control valves, No. three control valves and No. four control valves to can be in real time liquid level and PH control add the acid yield and business turn over water yield more, ensure that the PH of water just flows after up to standard.
