Description

Technical Field

[0001] This utility model relates to the field of complex matrix sample testing technology for elemental analyzers, specifically a high-salt wastewater sample testing device for elemental analyzers. Background Technology

[0002] An elemental analyzer is a precision instrument used to determine the elemental composition and content of substances. It is widely used in fields such as chemistry, materials science, environmental monitoring, pharmaceuticals, and geological exploration. Its core principle is to decompose the sample through physical or chemical means, use chromatographic techniques to detect the characteristic signals of elements, and then quantitatively analyze the target components. These instruments play an irreplaceable role in quality control, new material development, and pollutant tracing, and are key analytical tools in scientific research and industry.

[0003] When elemental analyzers test high-salinity wastewater samples, such as chlor-alkali saturated brine or seawater, if the sample is injected directly into the reaction tube, it will quickly pass through the quartz wool and reach the catalyst and reduced copper. This causes the catalyst surface to degrade rapidly due to salt buildup, and the reduced copper to become caked, reducing its permeability and significantly shortening its lifespan. Furthermore, it leads to instability in sample testing. Therefore, a method is needed to address the testing of these high-salinity wastewater samples. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing methods and provide a testing device for high-salt wastewater samples in an elemental analyzer. This device can obtain accurate test results without affecting the catalyst and copper reduction within the reaction tube, while also extending the lifespan of the reaction tube and reducing experimental costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-salt wastewater sample testing device for an elemental analyzer, comprising a quartz salt storage tube, a reaction tube, a reaction tube plug, and an oxygen injection tube; Quartz salt storage tube: made of quartz with multiple sieve holes on the surface, it is placed inside the reaction tube during use; The reaction tube is made of quartz, with quartz wool, copper reduction, and catalyst at the bottom, and a quartz salt storage tube in the upper space.

[0006] Reaction tube plug: made of brass, used to fix the upper end of the reaction tube and connect the oxygen injection tube; Oxygen injection tube: Made of aluminum oxide, used to inject the oxygen required for the reaction into the reaction tube.

[0007] Furthermore, the quartz salt storage tube is made of quartz material and has multiple sieve holes on its surface. It is placed inside the reaction tube during use.

[0008] Furthermore, the oxygen injection tube, made of alumina, is used to inject the oxygen required for the reaction into the reaction tube.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The high-salt wastewater sample testing device of this elemental analyzer has the following advantages: 1. Using quartz salt storage tubes to intercept samples with complex matrices prevents the samples from directly contacting the underlying catalyst and reduced copper, which helps extend the catalyst's lifespan and facilitates cleaning.

[0010] 2. It has no overly complex structure, is easy to modify, has low cost, and is simple to operate. Attached Figure Description

Quartz salt storage tube, 2. sieve, 3. reaction tube, 4. reaction tube plug, 5. oxygen injection tube, 6. quartz wool, 7. catalyst, and 8. reduced copper. Detailed Implementation

[0012] 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.

[0013] Please see Figs. 1-2 This embodiment provides a technical solution: a high-salt wastewater sample testing device for an elemental analyzer, including a quartz salt storage tube 1, a sieve 2, a reaction tube 3, a reaction tube plug 4, an oxygen injection tube 5, quartz wool 6, a catalyst 7, and reduced copper 8; Quartz salt storage tube 1: Made of quartz, with multiple sieve holes 2 distributed on it for air permeability. When the sample enters the quartz salt storage tube 1, oxygen is injected through the oxygen injection tube 5. After the sample and the sample react, the matrix part remains in the quartz salt storage tube 1, and the generated gas passes through the sieve holes 2 and enters the reaction tube to react and generate component gases.

[0014] Reaction tube 3: The interior is filled from bottom to top with quartz wool 6, reduced copper 8, quartz wool 6, catalyst 7, and quartz wool 6. Quartz salt storage tube 1 is placed on the top layer.

[0015] Reaction tube plug 4: Made of brass, used to fix the upper end of reaction tube 3 and connect oxygen injection tube 5.

[0016] This invention provides a high-salt wastewater sample testing device for an elemental analyzer: The main body is a reaction tube 3, with a quartz salt storage tube 1 placed in its upper part. A reaction tube plug 4 with an oxygen injection tube 5 is then installed. The reaction tube 3 is then placed in the instrument's heating furnace. When the sample is injected into the quartz salt storage tube 1 within the reaction tube 3, oxygen is added through the oxygen injection tube 5. The sample burns under the action of oxygen, and the generated gas enters the reaction tube 3 through sieve holes 2, passing sequentially through quartz wool 6, reduced copper 8, and catalyst 7, ultimately transforming into detectable component gases, ensuring the accuracy and reliability of the test results. High-salt and other matrix impurities in the sample remain in the quartz salt storage tube 1, without affecting the lifespan of catalyst 7 and reduced copper 8. After cooling, the quartz salt storage tube 1 can be directly removed for cleaning.
