Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figure 1 The image shows an integrated specific conductivity hydrogen conductivity detection device.

[0030] Example 1: An integrated specific conductivity and hydrogen conductivity detection device includes a sampling pipeline 100, a delivery unit, and a detection unit. The sampling pipeline 100 is used to deliver the water sample to be tested. The delivery unit includes a hydrogen conductivity delivery unit and a specific conductivity delivery unit connected in parallel. The sampling pipeline 100, the delivery unit, and the detection unit are connected in series. The detection unit is used to detect the specific conductivity or hydrogen conductivity of the water. In this example, the water sample is transmitted to the delivery unit via the sampling pipeline 100. By controlling the alternating opening and closing of the specific conductivity delivery unit and the hydrogen conductivity delivery unit in the delivery unit, the hydrogen conductivity and specific conductivity of the water sample can be detected separately without reassembling the equipment. This allows both detection operations to be performed on the same detection device, reducing the frequency of replacement and the complexity of operation, thereby improving ease of use and work efficiency. In addition, since the hydrogen conductivity delivery unit and the specific conductivity delivery unit are connected in parallel and connected in series with the sampling pipeline 100 and the detection unit, they can be combined into an integrated structure with higher integration, convenient on-site operation, and meeting the needs of rapid detection.

[0031] The detection unit comprises a flow meter 108, a measuring tank 109 and a measuring sensor 110. The flow meter 108 is connected to the sampling pipeline 100 through the specific conductance delivery unit and the hydrogen delivery unit. The measuring tank 109 is fixedly connected to the flow meter 108. A drain valve 112 is fixedly installed at the water outlet of the measuring tank 109. The measuring sensor 110 is fixedly installed in the measuring tank 109. The measuring tank 109 is externally provided with a measuring transmitter 111 electrically connected to the measuring sensor 110. During specific detection, the water quality sample delivered by the delivery unit enters the flow meter 108. The flow is adjusted to an appropriate range to ensure that the water sample can stably flow through the measuring tank 109. At the same time, the flow meter 108 displays the flow in real time to facilitate monitoring. After the water sample enters the measuring tank 109, the measuring sensor 110 measures the conductivity value of the water sample through the electrode and transmits the data to the measuring transmitter 111. The measuring transmitter 111 can display data and send the data to the external terminal at the same time, so as to achieve the conductivity detection of the water sample. In addition, the measured water sample can be concentratedly discharged through the opening of the drain valve 112, which is convenient for the measurement of subsequent water samples.

[0032] The hydrogen delivery unit comprises a hydrogen pipeline 101 and a hydrogen valve 104. The hydrogen pipeline 101 is fixedly connected to the sampling pipeline 100 and the detection unit at both ends, respectively. The hydrogen valve 104 is fixedly installed on the hydrogen pipeline 101. The hydrogen valve 104 is used to control the flow of liquid in the hydrogen pipeline 101. After the water sample flows into the hydrogen pipeline 101 through the sampling pipeline 100, the water sample in the hydrogen pipeline 101 can enter the measuring tank 109 through the flow meter 108 for measurement under the control of the hydrogen valve 104. When the hydrogen valve 104 is closed, the water sample enters the measuring tank 109 from the specific conductance delivery unit for measurement.

[0033] Further, the hydrogen delivery unit further comprises a cation resin ion column 107. The cation resin ion column 107 is arranged at one end of the hydrogen valve 104 away from the sampling pipeline 100. The hydrogen valve 104 is fixedly connected to the detection unit through the cation resin ion column 107. The cation resin ion column 107 contains resin. When the water sample passes through the cation resin ion column 107, impurity ions in the water sample, especially cations, can be effectively removed. Since impurity ions such as sodium, calcium and magnesium can interfere with the measurement results and cause the conductivity reading to be too high, removing the influence of these cations can improve the detection accuracy. After removing other cations in the water sample through the cation resin ion column 107, the concentration of hydrogen ions relatively increases, so that the measurement result is more stable and accurate.

[0034] In addition, in the prior art, the positive resin ion column 107 and the detection unit can be composed of a TW-9901 portable ion column and a TW-6196B portable conductivity meter, the TW-9901 portable ion column is provided with an ion column, a flow cell, a flow meter, a ball valve, a water sample interface and a shell structure, and the hydrogen conductivity of the water sample can be accurately measured by adopting the DL / T502.29-2019 water and steam analysis method for thermal power plants and the determination method of hydrogen conductivity, and the measurement accuracy of the online hydrogen conductivity meter can be improved by comparing and analyzing the measurement results of the portable hydrogen conductivity meter and the online hydrogen conductivity meter.

[0035] The specific conductance conveying unit comprises a specific conductance pipeline 102 and a specific conductance valve 105, the two ends of the specific conductance pipeline 102 are fixedly communicated with the sampling pipeline 100 and the detection unit respectively, and the specific conductance valve 105 is fixedly installed on the specific conductance pipeline 102 and is used for controlling the liquid flow in the specific conductance pipeline 102; when it is required to convey the water sample through the specific conductance conveying unit, the specific conductance valve 105 is opened, and the hydrogen conductance valve 104 in the hydrogen conductance conveying unit is closed, so that the water sample in the sampling pipeline 100 can flow into the measuring cell 109 through the specific conductance pipeline 102, and the specific conductance of the water sample is detected.

[0036] In the embodiment 2, the manual sampling unit composed of the manual sampling pipeline 103 and the sampling valve 106 is further arranged outside the conveying unit for manually extracting the water quality sample, the manual sampling pipeline 103 is arranged in parallel with the conveying unit and is communicated with the sampling pipeline 100, and the sampling valve 106 is fixedly connected to the end of the manual sampling pipeline 103 away from the sampling pipeline 100; when the specific conductance conveying unit and the hydrogen conductance conveying unit are both closed, the sampling valve 106 is opened, so that the water sample in the sampling pipeline 100 is discharged through the manual sampling pipeline 103, the required water sample is extracted, and the water sample is manually detected, the adaptability of the device is improved, and the diversified use demand is met.

[0037] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacement for some technical features, and any modification, equivalent replacement or improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
