Abstract
The utility model relates to an on-line detector for flow experiments, which comprises a detection chamber, a lower inlet, an upper inlet and an electrode sealing opening. The utility model is characterized in that the size of the detection chamber of the on-line detector is small, the fluid mixing possibility is low, and the timeliness and the accuracy of the on-line detection can be ensured. When the on-line detector is utilized, the on-line detection of parameters such as the pH value, the dissolved oxygen, the oxidation reduction electrode, the electrical conductivity and the like can be easily realized.
Description
Technical field
The utility model belongs to the detection technique field, is specifically related to a kind of pick-up unit.
Background technology
The online detection ratio of some physicochemical property is easier to realize that this mainly is that its flow is big in commercial production, and sensor can directly be immersed in the fluid, and seal and pressure bearing also is easier to.
But the indoor flowing experiment in a lot of fields is particularly simulated resource exploitation such as coal mining, oil recovery and original place and is leached in the flow test that the exploitation scientific research uses, and the flow of test is all very little.The flow of oil, ground-dipping uranium extraction fluidity test is usually all at 0.5～2.0cm
3Between/the min, pressure is between 0～20MPa.Under such condition, the measurement of some physicochemical property is as pH value, dissolved oxygen, oxidation-reduction potential, conductivity etc., because the volume of electrode or sensor is bigger, the volume capacity of online detection requirements is also big, can't guarantee its accuracy, real-time under the normal condition.Therefore, existing flowing experiment instrument generally all can't solve problem on line detection preferably.For example, in common " long apart from the leaching test device " of ground-dipping uranium extraction, [fault is the people, Tan Yahui once to adopt PHG-Z type acidity transmitter and FD type oxidation-reduction potential transmitter, Ceng Yijun, Wang Shude writes, and the original place is leached and adopted uranium reaction kinetics and material migration, Beijing: Atomic Energy Press: 154], because the detecting sensor volume is big, the experiment flow is little, goes back sample analysis in the experiment, is difficult to accomplish real-time detection; FDES-641 formation damage evaluating apparatus has been produced in the design of American core experiment company, this device has designed a special detection hole on core holding unit, the pH sensor can be inserted in the hole, and be close to the rock core wall, thereby detect the fluid pH value that flows through rock core, because the detected fluid flow is little, the probe liquid of flowing through can be representative poor, makes that institute's measured value is ageing, accuracy can not be satisfied with.
But the above character is adopted uranium, copper for resource exploitation that chemical reaction is arranged such as original place leaching, and microbe oil production is extremely important.Consider the weak point of existing flowing experiment instrument, need a kind of simple, practical on-line measurement device, to guarantee carrying out smoothly of on-line measurement.
Summary of the invention
The purpose of this utility model is to provide a kind of on-line measurement that can guarantee, and simple, the practical on-line measurement device that can carry out smoothly.
The technical solution of the utility model is as follows:
A kind of on-line measuring device, it comprises measuring chamber, wherein: described measuring chamber is a cylinder that has cavity, the bottom of this measuring chamber is provided with inlet, the top is provided with the electrode seal, electrode passes in the cavity that the electrode seal is arranged on measuring chamber, and the inner chamber of measuring chamber is consistent with electrode shape, and the sidewall upper of described measuring chamber is provided with liquid outlet.
In above-mentioned a kind of on-line measuring device: be provided with pressure cap and snap ring in described inlet and the liquid outlet, measuring chamber is fixedlyed connected high pressure line by pressure cap with snap ring.
In above-mentioned a kind of on-line measuring device: the spacing distance between the cavity inner wall of described measuring chamber and the external diameter of electrode is 0.5mm.
Remarkable result of the present utility model is: go out on advancing under the mobile employing of the mixing material in the measuring chamber, this can make, and the liquid mixing possibility reduces greatly in the measuring chamber, but for guaranteeing the measuring chamber pressure-bearing, import and export and adopt interior cutting ferrule to connect, the high pressure line that is the flow test instrument is connected with measuring chamber with pressure cap by pressure ring, this on-line measurement measurement device chamber volume is little, and fluid mixing possibility is little, has guaranteed ageing, the accuracy of online detection.
Description of drawings
Fig. 1 is the structural representation of on-line measuring device
Among the figure: 1 measuring chamber, 2 electrodes, 3 electrode seals, 4 inlets, 5 high pressure lines, 6 pressure caps, 7 snap rings, 8 liquid outlets.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, measuring chamber 1 is a cylinder that has cavity, the bottom of this measuring chamber 1 is processed with inlet 4, the top is equipped with electrode seal 3, electrode 2 passes in the cavity that electrode seal 3 is arranged on measuring chamber 1, the cavity of measuring chamber 1 is consistent with electrode 2 shapes, i.e. the parallel sidewalls of cavity inner wall and electrode 2, and the sidewall upper that is embedded in measuring chamber 1 in addition has liquid outlet 8.Electrode 2 in the present embodiment is long for 120mm, diameter 12mm.Described inlet 4 and liquid outlet 8 internal fixation are equipped with pressure cap 6, and mounting means can screw connects and is connected with pin or welds.High pressure line 5 is fixedlyed connected with measuring chamber 1 with snap ring 7 by pressure cap 6.
Spacing distance between the external diameter of the cavity inner wall of measuring chamber 1 and electrode 2 is 0.5mm.Like this, long for 120mm, the common size electrodes of diameter 12mm, after measuring chamber 1 was inserted electrode 2, the measuring chamber total measurement (volume) of φ 13 * 120mm was about 2.4cm
3, volume＜0.5cm around the electrode tip
3Because fluid is flowing, the fluid of 0.5～2.0ml/min flow by the electrode tip time between＜the 1min, suitable substantially with the response time of electrode, what can guarantee to measure is ageing.The spacing of measuring chamber 1 cavity inner wall and electrode 2 external diameters is 0.5mm, and this size is easy to processing, and inner total measurement (volume) is little, and the electrode tip safety in utilization is secure.
