Description
Technical field
The utility model relates to the chemical instruments pick-up unit, is specifically related to a kind of base exchanger failure monitor device.
Background technology
Ion-exchange is as the classical technique of industrial demineralized water disposal system, general in the water treatment field application, and its water outlet was lost efficacy and supervised the important monitoring index that also just becomes on-the-spot operation, and to systematic economy, operation has great significance.
Two kinds of modes that the base exchanger failure detection adopts at present:
The one, adopt anion exchanger to detect water power and lead, as shown in Figure 1, yin, yang ion- exchanger 3a, 2a connect mutually, and conductivity monitoring device 1a is arranged on the exit of anion exchanger 3a, after base exchanger 2a lost efficacy, conductivity monitoring device 1a records sodion; In the method generally only is applied in and forms unit system with anion exchanger, utilize anion bed to go out water power and lead change and judge whole element failure, and then the judgement cation bed lost efficacy.The method limitation is larger, only can be applied in unit system.
The 2nd, monitoring water outlet sodium ions content, as shown in Figure 2, online sodion analyser 1b is set, because positive resin only is better than hydrogen ion to sodion in the exchange selectivity of ion at the product mouth of a river of base exchanger 2b, so, when base exchanger lost efficacy, what go out to spill at first in water is sodion.The shortcoming that the method exists is: online sodion analyser 1b price is more expensive, and need to add basifier and regulate pH and measure, and has increased cost, and operation maintenance is all cumbersome etc.
The utility model content
The purpose of this utility model is to provide a kind of base exchanger failure monitor device.By above the resin bed of base exchanger, the water outlet of base exchanger respectively sets up a conductance measurement point, two conductance measurement points are carried out to measurement of comparison, overcome in existing two kinds of detection techniques the large or higher shortcoming of cost of limitation, thereby realized the purpose of this utility model.
The technical matters that the utility model solves can realize by the following technical solutions:
A kind of base exchanger failure monitor device, it is located in base exchanger, and this base exchanger comprises a resin bed, and the resin bed below is provided with produces the mouth of a river, wherein:
This base exchanger failure monitor device comprises a measuring circuit, this measuring circuit comprises the first measuring circuit that is arranged at resin bed and is arranged at the second servo loop that base exchanger produces place, the mouth of a river, be equipped with conductivity measuring device on this first, second measuring circuit, be provided with between first, second loop and measure the compare device.
In a preferred embodiment of the present utility model, the first measuring circuit is arranged at apart from 200～300mm place, resin bed bottom.
In a preferred embodiment of the present utility model, conductivity measuring device is specially online conductimetric analysis instrument.
The beneficial effects of the utility model are:
Supervise out more fast and effectively terminal, and apart from the inefficacy terminal, lead is to a certain degree arranged when detecting inefficacy, can guarantee to produce water water quality; Save more cost with respect to sodion analysis meter commonly used, and easy to operate, be conducive to production run and safeguard, and can be applied to the base exchanger of all size type, there is very strong practicality.
The accompanying drawing explanation
Fig. 1 is the schematic diagram that existing employing anion exchanger detects the equipment that water power leads.
The schematic diagram of the equipment of the sodion amount that Fig. 2 is the water outlet of existing detection base exchanger.
The schematic diagram that Fig. 3 is base exchanger failure monitor device described in the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 3, be provided with resin bed 330 in base exchanger 300, these base exchanger 300 tops are provided with water inlet 310, below is for producing the mouth of a river 320, water inlet 10 enters from this water inlet 310, after resin bed 330 carries out cation exchange, produces water 20 and discharges from producing the mouth of a river 320.
Measuring circuit described in the utility model comprises the measuring circuit 340 of being located on resin bed 330 and is arranged at the measuring circuit 350 that produces 320 places, the mouth of a river, be provided with successively respectively valve 341,351 and conductivity measuring device 342,352 on this measuring circuit 340,350, in the present embodiment, this conductivity measuring device 342,352 is specially online conductimetric analysis instrument.
Measuring circuit 340 specifically is arranged on the 200～300mm place, bottom apart from resin bed 330 in the present embodiment; Also be provided with between measuring circuit 340,350 and measure the compare device, for analyzing, contrast the measurement result of conductivity measuring device 342,352.
When the utility model specific works, the conductivity measuring device 342,352 in measuring circuit 340,350 is measured respectively the electricity of position separately and is led, and measures the compare device measurement result of conductivity measuring device 342,352 is contrasted; When resin bed 330 did not also lose efficacy, the measurement result of conductivity measuring device 342,352 is identical, when being positioned at resin bed 330 and starting to lose efficacy, the reading of the conductivity measuring device 342 of measuring circuit 340 starts to change, and the reading of the conductivity measuring device 352 on measuring circuit 350 is still constant, now measure the compare device and the numerical value deviation between conductivity measuring device 342,352 detected, judge that base exchanger 300 lost efficacy.
The utility model can be supervised out terminal more fast and effectively, and, when detecting inefficacy, resin bed 330 has the lead of 200～300mm apart from the inefficacy terminal, can guarantee to produce water water quality; Save more cost with respect to sodion analysis meter commonly used, and easy to operate, be conducive to production run and safeguard, and can be applied to the base exchanger of all size type, there is very strong practicality.
