Ion-exchange filter, chelate resin tower, activated carbon tower, catalyst tower etc..In addition, in addition to going to remove water to manufacture ultrapure water
Other than the water process of middle impurity, additionally it is possible to the removing applied to the impurities in liquid other than pure water manufacture.
As shown in Figure 1, being set side by side with multiple exchange resin towers 3 in water treatment facilities.Each exchange resin tower 3
Have: the ion exchange of the container and the identical type filled in the container with equal amount of same shape and same volume
Resin.For each exchange resin tower 3, treated water can be passed to via piping 1 and valve 2, processing water can be via valve 4 and piping
5 outflows.The water-flowing amount of each exchange resin tower 3 is measured with flowmeter (illustration omitted), each exchange resin tower 3
The water quality of processing water is measured by water quality detector 6.As water quality detector, it is able to use conductivity meter, nephelometer, residual chlorine
Densimeter, pH meter, resistrivity meter etc., but not limited to this.The water quality detector of the type suitable for hydrotreater can suitably be selected.
Among multiple exchange resin towers 3, by a part (in Fig. 1,1 tower of the leftmost side) A as test tower A,
Water flowing is carried out using the condition slightly harsh compared with other towers B (this as conditions of high flow rate) in tower A.Moreover, handing over ion
The water quality for changing the processing water of resin tower A continuously or intermittently monitors, grasps the sign deteriorated from stable state.It needs to illustrate
It is, therebetween for the water flowing SV of tower A, 1.05~1.3 times or so preferably for the water flowing SV of tower B.
It is big compared with the water flowing SV for tower B for the water flowing SV of tower A, therefore tower A more initial failure (processing water compared with tower B
Matter deteriorates).
For handling the sign of the water quality deterioration of water in tower A, grasped before the water quality deterioration of the processing water of tower B
Afterwards, in order to utilize the whole capability of tower A, B sufficiently (that is, to service life will use up), the residual life of tower B is predicted to carry out flow tune
It is whole, so as to which the processing water of fine water can be obtained to the maximum extent until adopting water and terminating.That is, reducing water flowing for tower A
Flow, or stop water flowing, the reduction part (or stop section) of the water-flowing amount for this tower A is appended to for other towers
The water-flowing amount of B.Impartial can be set as the water-flowing amount of each tower B, it can also chasing after the flow of the tower (tower C) of a part in tower B
Add part to be set as slightly higher compared with other towers B, and monitors the deterioration sign of the water quality treatment of tower C and predict the residual life of remaining tower B
(mark C omits icon).
The special mensuration machine of additional setting, control can be not required to for general water treatment system by above method
Under conditions of machine processed, target is maintained to handle water water quality, and will be to the greatest extent for all exchange resin tower water flowings to the service life
Only.Since even in the case where tower A (or tower C) detects water quality deterioration sign, water treatment facilities will not be reached at once
The whole service life, therefore the regeneration of hydrotreater, update can be made to carry out without difficulty after preparing to reach.
In Fig. 1,1 exchange resin tower is set as test tower A, but in the system for being set side by side with a large amount of towers,
In order to which the precision for predicting residual life more improves, settable multiple test tower A with slightly rigor condition water flowing, and make phase
There is difference for the severity (degree of high flow rate) of standard conditions.
[embodiment]
An example of the invention is described below in more detail.
For the service life of the treatment functions material such as ion exchange resin, as long as the water flowings such as flow (SV etc.)
Condition in the appropriate range, by load be the treated water to be removed in impurity concentration, with accumulate water flowing flow product it is big
It causes to determine.
As shown in Figure 1, starting most in the water treatment facilities for being set side by side with 10 exchange resin towers in water flowing
Just, for 1 tower A, with the flow velocity water flowing compared with standard high 10%, and it is directed to other towers B, after the segmentation of rest part equalization
Flow velocity water flowing.That is, with 11% water flowing speed of total water-flowing amount per unit time to water treatment facilities to tower A water flowing.
For remaining 9 tower B, respectively with water flowing speed (every list after sharing 89% equalization of total water-flowing amount per unit time
Respectively 9.89% water flowing speed of total water-flowing amount of the water treatment facilities entirety of position time) water flowing (89/9=9.89).
The feelings that the water flowing time until the water quality of the outflow water by tower A is shown at the time of deteriorating sign is 100 days
Under condition, the accumulation water-flowing amount to tower A until the 100th day, compared with standard conditions (by the 10% of total water-flowing amount equably water flowing
To the condition of each tower) accumulation water-flowing amount more 10%.Therefore, for tower 3 with the standard conditions water flowing, by place
The water flowing time (service life) until reason water quality starts to deteriorate can be estimated as 110 days.
Therefore, after the 100th day, to ensure that 1 tower A and other 9 tower B are the side of total water-flowing amount of total 10 amounts
Formula reduces the water-flowing amount of (or stopping) tower A and increases the water-flowing amount of tower B, and so that any one of tower A, B are cumulative loads
(water flowing start~adopt water and terminate during cumulative load) respectively becomes the negative of 110 days amounts in the case of standard conditions water flowing
The mode of lotus sets the water flowing number of days for each.
For example, the water quality requirement of processing water is harsh, and in the case where being impermissible for the impurity more than slightly sign, needle
To above-mentioned 1 tower A, being set as water flowing in this stage (the 100th day) terminates.For other 9 tower B, then it is set as standard conditions 10
Water flowing speed after 9 equal part of unit time water-flowing amount of platform amount, specifically, being set as standard conditions water flowing speed increases by 11.1%
Water flowing speed (100%/9=11.1%).
In the cumulative load of the tower B at 100 day moment, the case where being converted into standard conditions water flowing is 98.9 days amounts, is being marked
There is the remaining capacity of 11.1 days amounts in the case where floating screed part water flowing.Therefore, to increase by 11.1% water flowing speed, to become this
The mode of the cumulative load of 11.1 days amounts of standard conditions sets the 100th day later water flowing number of days.In this case, passing through it
The water flowing for carrying out 10 days afterwards, becomes this cumulative load.Therefore, for tower B, water can be adopted until the 110th day.
Life prediction and water-flowing amount control are carried out by the main points more than, each tower can be utilized to the maximum extent
A, the service life of B.
The high flow rate water flowing that 1 tower A can also be carried out to increasing in operating 20%, carries out increase by 10% for another 1 tower A
High flow rate water flowing, remaining 8 tower B is set as impartial water flowing.
Tower A can not be identical tower always, can be replaced every defined period.For example, being set side by side with 3
Tower a, b, c water treatment facilities in, in the case that standard water flowing speed is set as K, in an example, by the water flowing of tower a, b
Speed is set as 1.0K, and tower c is set as 1.2K, and when tower c shows the sign of water quality deterioration, the water flowing speed of tower a, b are set as
The water flowing speed of tower c is set as 0.8K by 1.1K, and by the service life use of each tower a, b, c to last.It, can also in other an examples
The water flowing speed of tower a, b are set as 1.0K, the water flowing speed of tower c is set as 1.2K, when tower c shows the sign of water quality deterioration,
The water flowing speed of tower a is set as 1.0K, the water flowing speed of tower b is set as 1.2K, the water flowing speed of tower c is set as 0.8K, makes tower b
The processing water water quality of tower b is monitored for high load capacity compared with tower a.
Though the present invention is described in detail using specific mode, as known to those skilled in the art, the present invention is not being departed from
Intention and range in can be carried out various changes.
