Description

Water sample analysis equipment

This application relates to an analytical device, and more particularly, to a water sample analysis device that can be analyzed for the amount of non-volatile total organic carbon in a water sample.

As people pay more attention to the environment, governments have regulated the non-volatile Total Organic Carbon (non-volatile Total Organic Carbon) content of water samples such as sewage and wastewater to reduce the environmental impact of sewage. Contamination, and therefore the industry's non-volatile total organic carbon analysis equipment is widely used to analyze the non-volatile total organic carbon content of water samples. Non-volatile total organic carbon analysis equipment, which usually oxidizes organic matter in water samples, and uses a water sample analyzer, for example, a Non-Dispersion Infrared Analyzer (NDIR) to measure water samples. The concentration of non-volatile total organic carbon.

In general, when the water sample analysis in the water sample analysis equipment is performed after the gas analysis operation of one stage is performed, some gas is inevitably left in the water sample analyzer, which is defined as the previous residual gas in the present application. The residual gas will greatly affect the gas analysis operation of the next stage of the water sample analyzer, resulting in a decrease in the accuracy of the analysis results.

Further, in the prior art, the method of oxidizing the organic substance in the water sample includes at least the following three types: a high temperature combustion method, a UV persulfate method, and a two-stage advanced oxidation method. For the high-temperature combustion method, the organic matter in the water sample is generally oxidized on the wall of the high-temperature furnace, which may cause residual substances on the wall of the high-temperature furnace, and the problems such as difficulty in derivation and cleaning are criticized. For the UV persulfate method, the persulfate is generally activated by UV light to generate hydroxyl radicals, and the organic substances in the water sample are oxidized. However, when the concentration of chloride ions (Cl-) in the water sample exceeds 0.05% At the time, the production of hydroxyl radicals is inhibited, and when the turbidity of the water sample is high, the UV light may be blocked, so that the activation of the persulfate is insufficient, so that the organic matter in the water sample cannot be completely oxidized. The analysis of the non-volatile total organic carbon content in the water sample is inaccurate. For the two-stage advanced oxidation method, the organic matter in the water sample is generally oxidized to carbon dioxide by the addition of an alkali agent (NaOH), and then the non-volatile total organic carbon in the water sample is analyzed by the measurement data of carbon dioxide. The content of the alkali agent will release carbon dioxide. Therefore, the use of the alkali agent may cause carbon dioxide which is not oxidized by the organic substance, and the analysis of the non-volatile total organic carbon content in the water sample is inaccurate.

Mix with the water sample and perform the inorganic carbon removal operation (please give details later).

The second carrier gas supply module 20 is selectively connected to the accommodating space 111 for providing a second carrier gas. In the present embodiment, the valve body V9 is opened or closed to communicate or cut off the transmission path between the second carrier gas supply module 20 and the accommodating space 111.

Furthermore, in the embodiment, the first carrier gas supply module 15 is a flow meter A, and the second carrier gas supply module 20 is a flow meter B, wherein the first carrier gas supply module 15 provides the first a first carrier gas of a flow rate, and the second carrier gas supply module 20 is configured to provide a second carrier gas of a second flow rate. In a preferred embodiment, the first flow rate is less than the second flow rate, wherein the first flow rate The size is defined by the allowable carrier gas flow rate of the water sample analyzer 12, and the second flow rate is preferably the flow rate of the carrier gas which is capable of forcing the carbon dioxide in the water sample to be released. In this embodiment, the flow rate of the flow meter A is designed to be 200 cc/min, and the flow rate of the flow meter B is designed to be 400 cc/min, but not limited thereto, due to inorganic carbon (TIC) in different water samples. The actual concentration (content) may be different. Therefore, by providing the independent first carrier gas supply module 15 and the second carrier gas supply module 20, the allowable carrier gas of the water sample analyzer 12 can be satisfied (ie, the first carrier is maintained). Under the premise that the flow rate of the module 15 is kept unchanged, the flow rate of the second carrier gas supply module 20 is separately adjusted according to the actual concentration of inorganic carbon in the water sample, for example, when the inorganic carbon in the water sample is actually When the concentration is high, the flow rate of the second carrier gas supply module 20 is increased, and when the actual concentration of the inorganic carbon in the water sample is low, the flow rate of the second carrier gas supply module 20 is lowered, thereby achieving the most Good reaction effect, thus improving the removal efficiency of inorganic carbon in water samples. However, it should be noted that the first carrier gas supply module 15 and the second carrier gas supply module 20 of the present application may also be combined into a single carrier gas supply module to meet the design requirements of simplifying the device composition.

In a preferred embodiment, the water sample analysis device 1 may further be provided with a carbon dioxide adsorbent that communicates with the first carrier gas supply module 15 and the second carrier gas supply module 20 for adsorbing the first carrier gas/second carrier. The carbon dioxide in the gas ensures that the first carrier gas/second carrier gas remains pure (excluding carbon dioxide), thereby avoiding the analysis of the water quality in the first carrier gas/second carrier gas. In the present embodiment, zeolite was used as the carbon dioxide adsorbent. In addition, in order to prevent the first carrier gas supply module 15 and the second carrier gas supply module 20 from being impacted by the high-pressure carrier gas and affecting the service life thereof, the first carrier gas supply module 15 and the second carrier gas supply module are A small pressure regulating gauge 22 may also be provided at the front end of 20 to adjust the input gas pressure of the carrier gas.

The gas supply module 15 communicates with the water sample analyzer 12, simultaneously closes the valve body V8, and activates the first carrier gas supply module 15, and provides the first carrier gas to the water sample analyzer 12 as a positive pressure air flow. A previously residual gas in the water sample analyzer 12 can be reversely entered into the accommodating space 111 along with the first carrier gas, and discharged into the accommodating space 111 via the opened fluid discharge line 13 by the backflushing operation to avoid The water sample analyzer 12 causes a problem that the subsequent analysis result is inaccurate due to the residual residual gas.

Referring to FIG. 2B and FIG. 1, when the execution module 10 performs the non-volatile total organic carbon analysis operation, the valve body V10 is closed to close the passage of the fluid discharge line 13, and then the pump P11 is started and the UV is turned on. The light supply module 14 and the water sample analyzer 12 are configured to circulate the water sample between the accommodating space 111 and the UV light providing module 14 to provide UV light to the water sample flowing through the UV light providing module 14 The non-volatile total organic carbon in the water sample is oxidized to form a non-volatile total organic carbon gaseous oxide. Then, the module 10 is opened to open the valve body V8 and the valve body V6 is switched to disconnect the first carrier gas supply module 15 a passage between the water sample analyzer 12 and the first carrier gas supply module 15 to supply the first carrier gas to the accommodating space 111 to force the release of non-volatile total organic carbon gaseous oxides in the water sample And entering the water sample analyzer 12 to analyze the content of the non-volatile total organic carbon in the water sample in the accommodating space 111.

In the present embodiment, when the pump P11 is turned on, the water sample circulation line 18 drives the water sample of the accommodating space 111 to enter the UV light supply module 14 from the circulating low water level L4 to be oxidized by UV light irradiation. The non-volatile total organic carbon in the water sample is formed to form a non-volatile total organic carbon gaseous oxide (for example, carbon dioxide), and the oxidized water sample will again flow to the circulating high water level L3 via the water sample circulation line 18. And entering the accommodating space 111 again, so as to achieve a circulating flow between the accommodating space 111 and the UV light providing module 14 in the water sample, thereby ensuring that the water sample of the accommodating space 111 can be smoothly oxidized. Furthermore, as described above, since the water level of the water sample accommodated in the accommodating space 111 is at the quantitative water level L2, and the circulating high water level L3 is higher than the quantitative water level L2, the water sample is again passed through the circulating high water level L3.

L2, thereby achieving the purpose of arranging a quantitative water sample in the accommodating space 111, and making the analysis condition of the water sample conform to expectations. It should be noted that, in the present application, when the execution module 10 performs the water sample introduction operation, the above-mentioned backflushing operation is simultaneously performed to transmit the first positive pressure to the water sample analyzer 12. In the process of performing the water sample introduction operation, the carrier gas can effectively prevent the water vapor generated in the water sample from entering the water sample analyzer 12, so that the water sample analyzer 12 is always kept in a dry state.

Referring to FIG. 2D and FIG. 1 , when the execution module 10 performs the inorganic carbon removal operation, the valve body V10 is opened to open the fluid discharge line 13 , and then the pumps P4 and P5 are activated to provide the medicine supply module 19 .
