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 the residue on the high-temperature furnace wall. Retaining substances, and deriving cleaning difficulties and other problems that have been criticized by people. 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.

The other aspects of the present application will be readily understood by those skilled in the art from the disclosure of the present disclosure. The application can also be implemented or applied by other different embodiments. The details of the present specification can be variously modified and changed without departing from the spirit and scope of the application. In particular, the proportional relationship and relative positions of the various elements in the drawings are for illustrative purposes only and are not representative of actual implementation of the application.

The present application provides a water sample analysis device for analyzing the content (concentration) of non-volatile total organic carbon in a water sample. For the technical idea of the present application, the following is exemplified with reference to the contents disclosed in FIG. 1 to FIG. 3, FIG. 4A to FIG. 4D and FIG. 5 in the drawings of the present application: Please refer to FIG. 1 to FIG. 3 , which are schematic diagrams showing the structure of an embodiment of the water sample analysis device 1 of the present application. As shown in FIG. 1 , the water sample analysis device 1 includes an execution module 10 , an apparatus body 11 , a water sample analyzer 12 , a UV light supply module 14 , a first carrier gas supply module 15 , an oxygen supply module 30 , and ozone. The generator 31 and the oxidant supply module 35 are provided. It should be noted that the architecture of the water sample analysis device 1 of the present application can be adjusted according to actual needs, rather than the architecture shown in FIG.

The interior of the device body 11 has an accommodating space 111 for accommodating a quantitative water sample.

The water sample analyzer 12 is connected to the accommodating space 111 for analyzing the non-volatile total organic carbon content of the water sample in the accommodating space 111. Preferably, the water sample analyzer 12 is a non-dispersive infrared analyzer (NDIR).

The oxidant supply module 35 is connected to the accommodating space 111 for supplying an oxidant to the water sample in the accommodating space 111. The oxygen supply module 30 is for supplying oxygen (O ₂ ) to the ozone generator 31. As shown in FIG. 3, the ozone generator 31 receives oxygen and discharges oxygen through the electrode 311 to generate ozone (O ₃ ). The ozone generator 31 is connected to the accommodating space 111, and oxygen can be supplied to the accommodating space 111 until the concentration of ozone in the accommodating space 111 is as expected, so that the chlorine ions in the water sample are removed by ozone, and the water sample is lowered. The chloride ion in the range affects the degree of oxidant action to solve the problem of salt interference in non-volatile total organic carbon analysis in water samples. Preferably, the expected ozone concentration in the accommodation space 111 is 50 mg/m ³ .

Preferably, as shown in FIG. 1, the water sample analysis device 1 may have an ozone concentration measurer 131, which is provided in the fluid discharge line 13 for measuring from the fluid discharge line 13 The fluid in the accommodating space 111 determines whether the concentration of ozone in the accommodating space 111 is in conformity with the expectation.

Preferably, as shown in FIG. 2, the water sample analysis device 1 may have a timer 32 that provides a timing for determining the duration of ozone generation by the ozone generator 31 to determine the space in the accommodation space 111. Whether the ozone concentration is in conformity with the expectation, the timer 32 can replace the ozone concentration measuring device 131 to determine the ozone concentration in the accommodating space 111.

The UV light providing module 14 is connected to the accommodating space 111 for providing UV light to the water sample containing the ozone and the oxidant flowing through the UV light providing module 14 to oxidize the non-volatile total organic carbon in the water sample to generate, for example, A non-volatile total organic carbon gaseous oxide that is carbon dioxide. Preferably, the UV light provided by the UV light providing module 14 has a light wavelength of 254 nm to provide ozone into hydrogen peroxide and then catalyze to hydroxyl radical (.OH), and oxidize the water sample by hydroxyl radicals. The organic matter oxidizes the non-volatile total organic carbon in the water sample to near completion, so that the water sample analyzer can accurately analyze the non-volatile total organic carbon content in the water sample.

As shown in FIG. 1 , the UV light providing module 14 of the present application is independently disposed outside the accommodating space 111 in an external manner, and is not built into the accommodating space 111 . The main advantage is that even when the water sample analyzing device is used 1 When performing a related operation other than the non-volatile total organic carbon analysis operation, for example, when the inorganic carbon removal operation is performed, the water sample in the accommodating space 111 can be prevented from entering the UV light supply mode by closing the water sample circulation line 18. The group 14 is such that, during the execution of the inorganic carbon removing operation, even if the UV light providing module 14 is turned on, the water sample in the accommodating space 111 is not affected by the UV light, and the non-volatile total organic in the water sample is avoided. The carbon is oxidized during the inorganic carbon removal operation. Thus, the UV light providing module 14 can be maintained in an open state at all times to reduce the number of restarts of the UV light providing module 14 and effectively improve the execution efficiency of the analysis operation.

The first carrier gas supply module 15 is selectively connectable to one of the water sample analyzer 12 or the accommodating space 111 for providing a first carrier gas.

By switching the valve body V6, the water sample analyzer 12 can be selectively The first carrier gas supply module 15 or the external space is in communication. When the valve body V6 is switched to make the first load When the gas supply module 15 is in communication with the water sample analyzer 12 and simultaneously closing the valve body V8, the first carrier gas supply module 15 can be supplied with the first carrier gas to the water sample analyzer 12; when the valve body V6 is switched When the passage between the carrier gas supply module 15 and the water sample analyzer 12 is disconnected and the valve body V8 is simultaneously opened, the water sample analyzer 12 is connected to the external space to discharge the analysis gas in the water sample analyzer 12. At this time, the first carrier gas supply module 15 is in communication with the accommodating space 111, and the first carrier gas is supplied to the accommodating space 111.

The execution module 10 can perform a non-volatile total organic carbon analysis operation, so that the ozone generator 31 supplies ozone to the accommodating space 111, and the oxidant supply module 35 provides an oxidant to the water sample, and then the ozone and the oxidant are mixed. The water sample circulates between the accommodating space 111 and the UV light providing module 14 to remove the chloride ions in the water sample by ozone to reduce the degree of influence of the oxidizing agent on the chlorine ions, and the UV light providing module 14 The water sample provides UV light to cause UV light, ozone, and oxidant to react to the water sample, while oxidizing the non-volatile total organic carbon in the water sample to form a non-volatile total organic carbon gaseous oxide, and then, first The carrier gas supply module 15 supplies a first carrier gas to the accommodating space 111 to force the non-volatile total organic carbon gaseous oxide in the water sample to be released, so as to enter the water sample analyzer 12 and be in the accommodating space 111. The content of non-volatile total organic carbon in the water sample was analyzed.

As shown in Figure 5, the symbol A refers to the standard water sample containing 30% chloride ion, and the non-volatile total organic carbon content in the water sample is carried out without removing the chloride ion of the standard water sample by ozone. The analysis results, and the symbol B refers to the analysis of non-volatile total organic carbon content in water samples in the case of standard water samples containing 30% chloride ions in the case of removal of chloride ions from standard water samples by ozone. result. Since the removal of chlorine from the standard water sample by ozone does not result in incomplete oxidation of the non-volatile total organic carbon, the measured value is lower than the actual value, so the area of the area indicated by the symbol A is smaller than the area indicated by the symbol B. The accuracy of the results of non-volatile total organic carbon analysis is not good, so the ozone is removed by ozone. Chloride ion can reduce the influence of chloride ion in water sample on the effect of oxidant to solve the problem that salt analysis in water sample interferes with non-volatile total organic carbon analysis and makes the analysis result inaccurate.

Preferably, the water sample analysis device 1 may have a water sample introduction line 16. Correspondingly, the accommodating space 111 has an overflow water level L1 and a quantitative water level L2, and the overflow water level L1 is higher than the quantitative water level L2.

The water sample introduction line 16 is provided with a pump P1, and the water sample is introduced into the accommodating space 111 by the water sample introduction line 16 through the startup pump P1. Furthermore, a valve body V7 is provided at the front end of the water sample introduction line 16, which can be designed as a three-way valve, and the water supply sample introduction line 16 can be selectively introduced from an overflow cup that is in communication with the remote sampling source.

At the position of the quantitative water level L2, the demand for accommodating a quantitative water sample inside the accommodating space 111 is satisfied, so that the analysis condition of the water sample is in line with expectations.

Preferably, the water sample analysis device 1 may have a water sample circulation line 18, and correspondingly, the accommodation space 111 is provided with a circulating high water level L3 and a circulating low water level L4, and the water sample circulation line 18 is connected to the apparatus body 11 The circulating low water level L4 of the accommodating space 111 is extended to the circulating high water level L3 of the accommodating space 111 via the UV light providing module 14 . The water sample circulation line 18 is provided with a circulation pump P11. When the circulation pump P11 is started, the water sample in the accommodating space 111 can be driven from the circulating low water level L4 to the circulating high water level L3 via the UV light supply module 14, and again The flow is returned to the accommodating space 111, thereby achieving the effect of circulating flow of the water sample between the accommodating space 111 and the UV light providing module 14. As shown in Figure 1, the cycle high water level The L3 system is higher than the quantitative water level L2, and the circulating low water level L4 is lower than the quantitative water level L2, and the water level of the water sample in the accommodating space 111 is at the height position of the quantitative water level L2, so that the water sample will be in the process of circulation. It is contributed by the high water level L3 of the circulation to the quantitative water level L2, which contributes to the release of the non-volatile total organic carbon gaseous oxide in the water sample. Preferably, the circulating high water level L3 is located between the overflow water level L1 and the quantitative water level L2, and the circulating low water level L4 is located at the bottom of the accommodating space 111 to meet the demand for sufficient circulation of the water sample.

Preferably, the water sample analysis device 1 may have a fluid discharge line 13 that communicates with the accommodating space 111 for discharging a gas (for example, carbon dioxide or the like) or a liquid (for example, a water sample, etc.) in the accommodating space 111. The fluid discharge line 13 is provided with a valve body V10 for controlling the opening and closing of the fluid discharge line 13. The fluid discharge line 13 extends from the overflow water level L1 of the accommodating space 111 to the outside of the apparatus body 11, and opens the valve body V10 to discharge the water sample in the accommodating space 111 beyond the overflow water level L1 by the fluid discharge line 13. Therefore, the water level in the accommodating space 111 is at the position of the overflow water level L1 at the highest, thereby avoiding an excessive amount of water in the accommodating space 111.

Two traffic. Since the actual concentration (content) of inorganic carbon (TIC) in different water samples may be different, by setting the first carrier gas supply module 15 and the second carrier gas supply module 20 separately, the first load may not be adjusted. Under the premise of the flow rate of the gas supply module 15, the flow rate of the second carrier gas supply module 20 is separately adjusted according to the actual concentration of the inorganic carbon in the water sample, thereby improving the removal efficiency of the inorganic carbon in the water sample.
