Water Distiller ​Cleaning Step​

Water Distiller cleaning Step

1, the preparatory work

a, close the steam valve, the distilled water to cool down to room temperature. Turn off the device;
b, closing the exhaust valve;
c, the "unqualified water outlet" and the inlet and outfall distilled water tank connected machine;
d, distilled water machine lifted all restriction orifice. Diameter of the orifice size vary, so before removing well marked, so that a smooth recovery after the cleaning is completed;
e, shed with water tower feed pan;
f, in the filled tank in deionized water;
g, circulation pump, the irrigation water distiller, until filled up.
h, regulating valves, deionized water, distilled water smoothly flows into the tank from the machine;

i, the exhaust valve open all the top of the tower, the tower exhaust air, so that the surface of the tower with the cleaning liquid contact. Exhaust gas after shut down.

2, cleaning

a, an acid solution is added to the tank (as previously required concentration added);
B, between the storage tank and distilled water machine circulation, the cleaning cycle time of 2 to 12 hours, determined according to the specific degree of fouling. Circulating cleaning solution temperature should meet the requirements;
c, the timing measured PH value, PH value between 1 to 2 as normal;
d, after the cleaning, the cleaning liquid is discharged to other good Jiong dealt with separately;
e, turn off the circulation pump;

f, rinsed with deionized water for about 1 hour. When the PH value reaches 5-7, stop flushing, venting and flushing water.

3, if both of boiler scale and silica scale cleaning. As above, with the solution before introduction. If there is no silica scale, and can enter the stage.

4, and stage

a, the machine filled with distilled water, deionized water and discarded column of air;
b, according to the aforementioned request to join the concentration and solvent, and circulated;
c, and the time is about 1 hour;
d, during and after the end of the emissions and liquid;

e, closed circulation pump.

5, the end of the operation

a, open all the discharge nozzle;
b, distilled water, deionized water until the washing machine and no foam returns to normal PH value (PH = 7);
c, shed cleaning joints;
d, open at both ends of the flange of the tower to observe the cleaning effect and cleaning with liquid dish;
e, replace the machine with a drip pan under the flange. Fixed upper and lower flanges, the operation carefully, because the distillation column is a pressure vessel;
f, replace the throttle plate, being careful premade mark recovery;

g, according to the above principles and methods for cleaning condenser cooling water for cleaning.
