Abstract
The utility model provides a mobile detection device of online intermittent type of quality of water which includes: the flow -through cell is located sample input tube and waste liquid discharge pipe on the flow -through cell, wherein, the sample input tube on be equipped with the reagent input tube. This kind of mobile detection device of online intermittent type of quality of water, the less sample input tube of pipe diameter is arrived in reagent intermittent type's injection to reduce sample and reagent quantity, reduced the online volume that produces the waste liquid in the monitoring that lasts simultaneously.
Description
Technical field
The utility model relates to water quality online measuring technique field, particularly relates to a kind of for the online intermittent flow pick-up unit of water quality.
Background technology
At present, existing photometry on-line detector on the market, instrument fluid path structure is comparatively complicated, need join in reaction cup by quantitative chemical reagent and water sample during detection, it is made to develop the color completely by being uniformly mixed, then by the concentration of specific colorimetric device determination material.Continuous sample introduction colorimetric or introduce colorimetric again after reaction in reaction cup, need consume a large amount of reagent during test, cause cost waste, greatly, environmental protection coefficient is low for the waste liquid amount simultaneously produced; In addition, although can avoid within a certain period of time after the instrument calibration of such device safeguarding, the change of instrument to be noted in testing the moment, and regularly carry out calibrating to instrument and clean, bring larger working pressure to staff.
Such as: present most of chlorine residue on-line detector on the market, have employed photometry to be combined with DPD chemical reagent and to detect chlorine residue in water, require to employ larger water sample amount and amount of reagent in order to accuracy of detection can be reached, waste liquid amount after general single test at about 25-50mL, waste liquid amount very large during follow-on test; Because apparatus structure is complicated when safeguarding, need dismounting instrument, cleaning reaction cup, change pipeline etc., complex operation and also technical requirement higher.
Utility model content
The purpose of this utility model is to provide a kind of water quality on-line checkingi to sample bubble trap, and for solving pick-up unit in prior art, maintenance cost is high, reagent and amount of samples large, the technical matters that waste liquid generation is higher.
For achieving the above object, the technical scheme that the utility model proposes is:
The online intermittent flow pick-up unit of a kind of water quality of the present utility model, it comprises: flow cell, is located at the sample input pipe on described flow cell and waste liquid vent pipe, and wherein, described sample input pipe is provided with reagent input pipe.
Wherein, described sample input pipe and waste liquid vent pipe are all located at the top of described flow cell.
Wherein, the below of described sample input pipe is located at by described reagent input pipe.
Wherein, described reagent input pipe entrance point is also provided with a reagent injection device.
Wherein, described reagent injection device is interval priming device.
Wherein, described waste liquid vent pipe single waste liquid discharge rate is less than 4ml.
Compared with prior art, the online intermittent flow pick-up unit of a kind of water quality of this utility model, reagent interval be injected into the less sample input pipe of caliber, thus decrease sample and reagent dosage, reduce the amount continuing to monitor middle generation waste liquid online simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the online intermittent flow pick-up unit of the utility model water quality.
Embodiment
Below with reference to accompanying drawing, elaboration is further given to the utility model.
Refer to accompanying drawing 1, this kind of online intermittent flow pick-up unit of water quality, comprising: flow cell 1, is located at the sample input pipe 2 on described flow cell and waste liquid vent pipe 3, and wherein, described sample input pipe 2 is provided with reagent input pipe 4.
More specifically, described sample input pipe 2 and waste liquid vent pipe 3 are all located at the top of described flow cell 1.
Wherein, the below of described sample input pipe 2 is located at by described reagent input pipe 4.
Wherein, described reagent input pipe 4 entrance point is also provided with a reagent injection device, and this reagent injection device is not shown in the drawings.
Wherein, described reagent injection device is interval priming device.After tested, described waste liquid vent pipe single waste liquid discharge rate is less than 4ml, while not affecting testing result precision, greatly reduces reagent and amount of samples.
The online intermittent flow pick-up unit of a kind of water quality of the present utility model, its core idea is: removed by the reagent sample reaction tank in existing pick-up unit, change into, reagent is directly added in sample input pipe, and the caliber of reagent input pipe is very little, simultaneously, reagent adopts interval injection mode, when not affecting accuracy of detection, can reach, saving the object of sample and reagent dosage.
Foregoing; be only preferred embodiment of the present utility model; not for limiting embodiment of the present utility model; those of ordinary skill in the art are according to central scope of the present utility model and spirit; can carry out corresponding flexible or amendment very easily, therefore protection domain of the present utility model should be as the criterion with the protection domain required by claims.
