Description

The portable dissolved oxygen table of a kind of self-seal type flow cell
Technical field
The utility model relates to the oxygen analyser of measuring in water, relates to the portable dissolved oxygen table of a kind of self-seal type flow cell.
Background technology
The solubleness of oxygen in water depends on the salt content in temperature, pressure and water.Portable dissolved oxygen analytic instrument can be measured the oxygen level in water, mainly adopts electrochemical principle to measure.Portable dissolved oxygen analytic instrument transducing part is made up of gold electrode (negative electrode) and silver electrode (anode) and potassium chloride or potassium hydroxide electrolyte, and oxygen diffuses into electrolytic solution and gold electrode and silver electrode by film and forms measuring circuit.In the time adding the polarizing voltage of 0.6~0.8V to dissolved oxygen analytic instrument electrode, oxygen spreads by film, and negative electrode discharges electronics, and anode is accepted electronics, generation current, and whole course of reaction is: anode: Ag+Cl -→ AgCl+2e -negative electrode: O 2+ 2H 2o+4e → 4OH -according to Faraday's law: the electric current and the partial pressure of oxygen that flow through dissolved oxygen analytic instrument electrode are directly proportional, linear between electric current and oxygen concentration temperature-resistant in the situation that.
The effect of dissolved oxygen analytic instrument flow cell: a. fixed electorde, b. water conservancy diversion.
The requirement of dissolved oxygen analytic instrument flow cell: a. has some strength, b. good airproof performance, c. is conducive to Exhaust Gas, and d. is convenient for changing.
Tradition flow cell liquid in the time measuring, by the inlet pond that circulates, then flows out from liquid outlet.The oxygen dissolving in electrode pair mobile phase is measured.Tradition flow cell inlet in the time measuring is connected on sampled point, measures complete laggard liquid mouth and takes off from sampled point.At this moment because liquid outlet is higher than inlet, the water in flow cell can flow out from inlet, causes electrode to be exposed in air, causes Measuring Time to lengthen while again measurement.
Utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, the portable dissolved oxygen table of a kind of self-seal type flow cell is provided, the part that when oxygen that this device can make to dissolve in electrode pair mobile phase is measured, electrode bottom is played to measurement effect seals, thereby reduces Measuring Time.
The purpose of this utility model is to solve by the following technical programs the problems referred to above:
The portable dissolved oxygen table of a kind of self-seal type flow cell, comprise the electrode being connected with manipulater display screen, described electrode is connected on electrode flow-through cell and is inclined in flow cell body, is respectively equipped with the feed liquor interface being connected by pipeline with electrode flow-through cell and goes out liquid interface on described flow cell body; In described flow cell body, be filled with water, and water level liquid level is concordant with the position of feed liquor interface.
Preferably, described feed liquor interface by feed liquor extension tube be arranged on electrode flow-through cell bottom and be connected.
Preferably, described in go out on the flow cell body sidewall that liquid interface is located at feed liquor interface top, and go out on liquid interface and feed liquor interface to be respectively equipped with valve.
With respect to traditional flow cell, liquid level in flow cell flow cell of the present utility model is concordant with the position of inlet, self-seal type flow cell is complete in measurement, and the water retaining in flow cell can be sealed in the gold electrode of electrode bottom in water, thereby realizes self-packing effect.
The advantage of the utility model self-seal type flow cell:
A. the part that self-seal type flow cell can play electrode bottom measurement effect seals.
B. reduce Measuring Time.
Brief description of the drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model structural representation.
Wherein: 1, electrode; 2, electrode flow-through cell; 3, flow cell body; 4, feed liquor extension tube; 5, feed liquor interface; 6, go out liquid interface; 7, fixed screw.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
As shown in Figure 1, the portable dissolved oxygen table of a kind of self-seal type flow cell, comprise the electrode 1 being connected with manipulater display screen, electrode 1 is connected on electrode flow-through cell 2 and is inclined in flow cell body 3, is respectively equipped with the feed liquor interface 5 being connected by pipeline with electrode flow-through cell 2 and goes out liquid interface 6 on described flow cell body 3; In described flow cell body 3, be filled with water, and water level liquid level is concordant with the position of feed liquor interface 6; Feed liquor interface 5 by feed liquor extension tube 4 be arranged on electrode flow-through cell 2 bottoms and be connected, go out on flow cell body 3 sidewalls that liquid interface 6 is located at feed liquor interface 5 tops, and go out on liquid interface 6 and feed liquor interface 5 to be respectively equipped with valve.
In this device, electrode is the device that according to electrochemical principle, the concentration signal of dissolved oxygen DO is converted into electric signal.Electrode flow-through cell plays fixed electorde and provides continuously measurement liquid to electrode, and electrode flow-through cell adopts inclined type, prevents that gas from assembling at electrode surface.Feed liquor import and fluid outlet are by the device of solution input and output flow cell to be measured.
Liquid level in the portable dissolved oxygen table of self-seal type of the present utility model flow cell is concordant with the position of inlet, complete in measurement at self-seal type flow cell, by the valve closing being located at out on liquid interface and feed liquor interface, the water retaining in flow cell can be sealed in the gold electrode of electrode bottom in water, thereby realizes self-packing effect.
By gib screw 7, flow cell body 3 is fixed on portable dissolved oxygen analytic instrument.
The technical scheme above the utility model embodiment being provided is described in detail, applied principle and the embodiment of specific case to the utility model embodiment herein and set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in embodiment and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
