Abstract
The utility model provides an online slit density index measurement multi-path sample switching device, which comprises an online slit density index analysis meter, wherein a sample inlet end of the online slit density index analysis meter is provided with N paths of sample inlet pipes which are connected in parallel; each path of sample inlet pipe is provided with a switch solenoid valve; a control end which is provided with a sample switching controller and connected with the solenoid valve is used for controlling connection and disconnection of a sample pipe; and N is 2 to 6. The online slit density index measurement multi-path sample switching device has a multi-channel function, so that the measurement meter can be used for measuring multiple samples in a time-sharing mode, and the meter purchase and operation cost can be greatly saved; and each channel can be programmed, closed or opened, thus the online slit density index measurement multi-path sample switching device is convenient to operate.
Description
Technical field
The utility model relates to a kind of online SDI (pollution index) analysis meter, switches in the time of can realizing multichannel appearance moisture, also can close or open multichannel appearance water gaging according to programmed control.
Background technology
In the reverse osmosis water processing procedure, the SDI value is one of important symbol of measuring the counter-infiltration system water inlet; Be the main the means whether water outlet of check pretreatment system reaches the feed water by reverse osmosis requirement.Its size is most important to counter-infiltration system operation life.The SDI value is to measure through the 47mm diameter, the decay of the flow velocity of 0.45um aperture film.Why selecting the film in 0.45um aperture, is because under this aperture, and colloidal material is than grit material (like sand, incrustation scale etc.) easy blocking film more.The decay of flow velocity is converted into the numerical value between 1 to 100, i.e. the SDI value.The SDI value is low more, and water is more little to the pollution obstruction trend of film.
SDI (pollution index) analysis meter assay method: put into the filter membrane anchor clamps to the filter membrane of 0.45 μ m, open valve, and adjust pressure to 30psi and maintenance, collect water sample and also pick up counting, the required time of 500mL water sample collected in record is T0 (second).Water sample flowed after 15 minutes, collected 500mL water sample and record collection water sample institute's time spent with container once more, and note is made T15 (second).According to computes SDI value: SDI=(1-T0/T15) X100/15.
The precision that online SDI analysis meter is measured the water yield directly influences SDI result of calculation.
The SID analysis meter was only measured one tunnel appearance water in the past, because appearance water actual change trend is unhappy, if can carries out the pollution index of multichannel water and measure, and the SID analysis meter can alternately be measured multichannel, can reduce instrument buying and operating cost greatly.
Summary of the invention
The utility model purpose is: online pollution index is measured multichannel appearance water switching device shifter, makes the SID analysis meter alternately measure multichannel appearance water, can reduce instrument buying and operating cost greatly.
The utility model scheme is: online pollution index is measured multichannel appearance water switching device shifter; It is characterized in that comprising online pollution index analysis meter; The appearance water inlet end of online pollution index analysis meter is provided with the N road appearance water inlet pipe of parallel connection; Every road appearance water inlet pipe is provided with solenoid valve, is provided with the control end that kind water switch controller connects solenoid valve the appearance water pipe is opened and turn-offed; N is the 2-6 road.
Be divided into 4 the tunnel like N, be numbered A/B/C/D respectively, controller is through program setting (therefore solenoid valve also receives programmed control); As measuring wherein three road A/B/D, then sample introduction water A at first measures the back outputting measurement value to first via output; Measure successively then; Skip C, measure B and D, and output to corresponding passage respectively.The signal output of corresponding every road is measured in each kind water loop.
When needs are opened corresponding solenoid valve, appearance water passes through, and the appearance water of not opening solenoid valve can not pass through, flushing pipeline 1 minute earlier when switching to next road appearance water, and then measure.Detect whether a kind water is arranged during flushing, if there is not a kind water, this road appearance water disappearance is described, program will be directly switch to next road and measure.
Online pollution index is measured multichannel appearance water switching device shifter, and all passages can be programmed, and open or close, and when appearance water has pressure, can not close measurement automatically, jump into next passage.
The beneficial effect of the utility model is: have multi-channel function, make measurement instrument timesharing to measure a plurality of kinds of water, practice thrift instrument buying and operating cost greatly; Each passage can be programmed, and closes or opens, convenient operation; When appearance water lacked pressure, Automatic Program was closed this passage, avoided the waste of time and measuring diaphragm; Every road appearance water all has output channel one to one.
Description of drawings
Fig. 1 is a kind of online SDI analysis meter multichannel appearance water switching device shifter of the utility model,
Appearance water switch controller 1, SID analysis meter 2, solenoid valve 3, A, B, C, D are four tunnel appearance water.
Embodiment
In conjunction with the accompanying drawings, the embodiment explanation and the method for operation are following:
Every road appearance water has solenoid valve when advancing instrument, and solenoid valve receives programmed control.
Measuring method: when needs are opened corresponding solenoid valve, appearance water passes through, and the appearance water of not opening solenoid valve can not pass through, flushing pipeline 1 minute earlier when switching to next road appearance water, and then measure.Detect whether a kind water is arranged during flushing, if there is not a kind water, this road appearance water disappearance is described, program will be directly switch to next road and measure.
