Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention is described in detail.
A kind of head tank adding method thereof, comprising the following steps: high-order dosing batch meter 1 is added by inlet tube 3 in medicament
In, the two position of high-order dosing batch meter 1 is set, the amount of control institute's adding medicine is between two position；Establish batch meter
Liquid level and the drain flow velocity table of comparisons calculate the unit time lifting rate V for having feed liquor process to participate according to the table of comparisons；By the list
Position time lifting rate V is compared with unit time estimated lifting rate V ', according to comparison result, and then controls liquid feed valve 2 and row
Adding for medicament is realized in the movement of liquid valve 5.
The present invention also provides a kind of head tank medicine systems, including high-order dosing batch meter 1, liquid feed valve 2, inlet tube 3, liquid
Position meter 4, tapping valve 5, lifting rate control unit 6, the inlet tube 3 are located at high-order dosing batch meter 1, and tapping valve 5 is located at a high position
1 side lower part of dosing batch meter, liquidometer 4 is inserted into high-order dosing batch meter 1 in medicament, described for measuring the liquid level of medicament
Respectively at 6 electrical links of lifting rate control unit, the lifting rate control unit 6 is stored with for liquid feed valve 2, liquidometer 4, tapping valve 5
Liquidometer measuring tank liquid level and the drain flow velocity table of comparisons, and the unit time drain for having feed liquor process to participate in is calculated according to the table of comparisons
Measure V, the lifting rate control unit 6 by unit time lifting rate V and unit time it is expected that lifting rate V ' is compared, according to than
Compared with as a result, lifting rate control unit 6 controls liquid feed valve 2 and adding for medicament is realized in the movement of tapping valve 5.
According to the knowhow of many years, when reagent adds, put into process flow at times according to technology Calculation dosage.
Dosage Q can be calculated with the liquid level falling head δ h of measuring tank in unit time δ T, Q=δ h × S, and wherein δ h is liquidometer detection
Liquid level changing value, S is measuring tank sectional area.If Q is greater than or equal to the dosage Q ' calculated, it is next to close blow-off valve waiting
Time cycle opens, and the lifting rate Q in period δ T is less than the dosage Q ' calculated, opens liquid feed valve and improves liquid level, increase is matched
Flow velocity, the lifting rate that upper a period of time is owed are added to next period.
