Description
Technical field
The present invention relates to the softening resin regeneration controls of softening field of water treatment equipment, more particularly to softening water treatment facilities
Method.
Background technique
Softening water treatment facilities control valve Control Cooling is generally two classes currently on the market, i.e., mechanical and electronic type.Machine
Tool formula generally relies on gear and stepper motor transmission to control the switching and timing of softening resin regeneration step, and such product is to again
The sequence and time majority of raw step are non-adjustable or are adjusted in seldom range.Electronic type then relies on wiring board and electricity
The switching and timing of machine control softening resin regeneration step.Such product flexibility is larger, but flexibility is only in setting value model
Larger, accurate measurement is enclosed, triggering mode is still relatively simple as mechanical, can not embody too many advantage.
The resin regeneration control method of softening water treatment facilities softening at present generally divides three kinds, time control, flow control and
Flow-time co- controlling.The general setting interval number of days of time type control and reproduction time point, operation to reproduction time point trigger
The shortcomings that regeneration, this type, is not confirming the use state of softening resin, either still set more than the softening amount of resin
Aliphatic radical sheet is unused, all can be by regenerant salt come 100% regenerating resin.The control of flow type is the supplement to time type control, setting
After fixed softening amount, measured by flowmeter.100% regeneration immediately softens resin after softening water setting value is finished.This
The advantages of method, makes full use of for resin, the disadvantage is that randomness is big and user is excessively conflicted with water time point for reproduction time section.
Flow-time control type to both the above method be one supplement, i.e., first use flow measurement, flow be finished after in 24 hours by
100% regenerating resin of setting time point, although the method passes through flow measurement and reproduction time point is controlled, flow arrives after being finished
Point this period reproduction time, it is possible that the problem of softening efficiency lost resin.
Summary of the invention
Goal of the invention: being directed to prior art problem, and it is an object of the present invention to provide a kind of the soft of new softening water treatment facilities
Change resin regeneration control method, this method can not only fail to avoid softening resin, but also can save the dosage of regenerant salt.
To achieve the goals above, present invention employs the following technical solutions: a kind of softening softening water treatment facilities
Resin regeneration control method, this method comprises:
In the reproduction time point of the dry period setting softening resin of user；
Softening resin regeneration is calculated the time required to dissolving according to reproduction time point, the regenerant salt of softening resin judges the time
Point, calculation formula are as follows:
The time required to softening resin regeneration judges that time point=softening resin reproduction time point-regenerant salt dissolves；
When softening water treatment facilities, which are run, judges time point to softening resin regeneration, according to the surplus of softening water treatment facilities
Remaining water consumption VsyAnd daily average consumption VpJ judges to soften whether resin needs to regenerate, if Vsy≤VpJ × K, then into
Row softening resin regeneration, if Vsy> Vpj× K, then without softening resin regeneration, wherein K is safety coefficient.
Further, it when carrying out softening resin regeneration, is first filled the water, waits regenerant salt to dissolve after water filling, dissolved salt
Softening resin regeneration is carried out after the completion；Water injection time salt amount according to needed for resin loading, every liter of resin regeneration, every liter of water soluble
Salt amount, the unit time water injection rate for filling the water part have softened water consumption, softening resin production water inventory calculating, and calculation formula is as follows:
Water injection time=(resin loading × salt amount needed for every liter of resin regeneration × has softened water consumption) (every liter of water can by ÷
Dissolved salt amount × water filling part unit time water injection rate × softening resin produces water inventory).
Further, the remaining water consumption Vsy, daily average consumption VpJ produces water inventory, soft according to softening resin
Change water consumption, days running calculating, calculation formula are as follows for softening water treatment facilities:
Remaining water consumption Vsy=softening resin produces water inventory-and has softened water consumption；
Daily average consumption VpJ=has softened water consumption ÷ softening water treatment facilities days running.
Further, the softening resin production water inventory can be with the hard of sofening treatment according to resin loading, every liter of resin
Angle value, water inlet hardness calculation, calculation formula are as follows:
Soften resin and produces water inventory=(resin loading × every liter of resin can be with the hardness number of sofening treatment) ÷ water inlet firmly
Degree；
The water consumption that softened passes through the flowmeter measurement being mounted on softening water treatment facilities.
Further, the safety coefficient K value range is 1.0~1.5.
Compared with existing softening water treatment facilities soften resin regeneration control method, the present invention has following advantages:
(1) reasonability controlled.In user's dry time point regeneration, budget valuation in advance retains one day or so soft
Change surplus, so that being not in the phenomenon that having the time that can not soften；
(2) reasonability and safety that softening resin utilizes.Estimating reserved is that usually water consumption calculates according to user
Out, softening resin utilization rate is improved to greatest extent, and at least there are one day softening surplus while increasing operation rate,
Even if seldom a bit than " retention " height, can still may be implemented before being regenerated normal to guarantee " remaining water consumption " just
Softening function.
(3) the reasonable saving dosage of regenerant salt.Traditional softening resin regeneration mode is typically all 100% regeneration.It is this
Though mode is not in the incomplete problem of regeneration, waste more serious.The method of the present invention softens efficiency lost resin according to practical
Dosage is regenerated, and is calculated by the time of water filling to control the amount of salting liquid, final control regeneration salt dosage, compared with traditional soft
The salt dosage of 20%-30% can be saved by changing resin regeneration mode.
Detailed description of the invention
Fig. 1 is the softening resin regeneration control method block diagram of softening water treatment facilities of the invention.
Specific embodiment:
Further explanation is done to the present invention with reference to the accompanying drawing.
