[0024] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-6 This utility model provides a technical solution for a combustion analysis instrument with a protective structure:

[0027] A combustion analysis instrument with a protective structure includes a combustion component 1 for burning a combustible material and converting specific elements or energy in the sample into a measurable gaseous form; an analysis component 2, fixedly connected to one side of the combustion component 1, for analyzing the composition of the gas produced by combustion; and a purification component 3. The analysis component 2 is based on existing technology, and its principle is to remove interfering components such as water and impurity gases from the gas produced by combustion, convert the specific gas into a detectable form, then use a gas chromatography column to achieve physical separation, and finally use a thermal conductivity detector, a non-dispersive infrared detector, etc. to detect and analyze the separated gas. The purification component 3 is located on the top of the analysis component 2 and is connected to the exhaust port 21 of the analysis component 2.

[0028] Specifically, by burning the combustible material in the combustion component 1, specific elements or energy in the sample are converted into a measurable form, namely gas. The gas produced by combustion enters the analysis component 2, which is used to detect it and calculate the content of elements such as carbon, hydrogen, nitrogen, and sulfur in the sample. The purification component 3 removes harmful gases such as SO2, NOx, HX, and CO from the exhaust gas before it is emitted, thus protecting the environment and solving the problem of pollution caused by direct emission of exhaust gas in existing technologies.

[0029] Purification component 3 includes a housing 31, within which an exhaust channel 32 is formed. From bottom to top, the inner wall of the exhaust channel 32 is fixedly connected to an acid gas neutralization section 33, a catalytic oxidation layer 34, and an activated carbon adsorption layer 35. The acid gas neutralization section 33 removes SO2, HCl, and HF, while the catalytic oxidation layer 34 converts CO into CO2 and degrades NO. x The activated carbon adsorption layer 35 adsorbs residual organic matter, ozone and trace amounts of Hg to achieve the purpose of purifying the exhaust gas.

[0030] The acid gas neutralization section 33 includes a stainless steel wire mesh 331 at the bottom, and a pre-pressed disc filter body 332 is fixed on the top of the stainless steel wire mesh 331 for supporting the disc filter body 332. The disc filter body 332 includes a calcium oxide layer 3321, a sodium hydroxide layer 3322, and a calcium fluoride layer 3323. The disc filter body 332 is pre-pressed from calcium oxide particles, sodium hydroxide particles, calcium fluoride particles, and a binder to prevent the particles from loosening and causing channeling.

[0031] The catalytic oxide layer 34 is a honeycomb ceramic carrier internally coated with bimetallic oxides.

[0032] A filter screen 36 is fixedly connected to the inner wall of the exhaust channel 32. The filter screen 36 is located at the bottom of the acid gas neutralization section 33 and is used to intercept large particles in the gas.

[0033] The bottom of the outer casing 31 is integrally formed with a connector 311 with an internal thread on the inner wall. The surface of the exhaust outlet 21 is provided with an external thread that matches the internal thread. The connector 311 is threadedly connected to the exhaust outlet 21. By setting the connector 311, it is convenient to disassemble and replace the purification component 3.

[0034] Combustion assembly 1 includes a protective box 11. A top cover 12 is fixedly connected to the top of the protective box 11. A combustion chamber 13 with an upward opening is fixedly connected to the lower surface of the top cover 12 for combustion of the combustion sample. An output pipe 14 is fixedly connected to the bottom wall of the outer wall of the combustion chamber 13. The output pipe 14 is connected to the analysis assembly 2 for introducing the gas generated by combustion into the analysis assembly 2. An input pipe 15 is fixedly connected to the top of the outer wall of the combustion chamber 13. One end of the input pipe 15 extends to the outside of the protective box 11 for connection to an external oxygen and inert gas storage device so as to introduce sufficient oxygen and inert gas into the combustion chamber 13. The oxygen is used to supply combustion, and the inert gas is used to push the gas generated by combustion into the analysis assembly 2.

[0035] A sealing seat 16 is provided on the top cover 12. A connecting rod 17 is fixedly connected to the bottom of the sealing seat 16. A crucible 18 is fixedly connected to one end of the connecting rod 17. An igniter 19 is fixedly connected to the bottom of the sealing seat 16. An electric slide 4 is fixedly connected to the back of the protective box 11. A transmission rod 5 is fixedly connected to the output end of the electric slide 4. One end of the transmission rod 5 is fixedly connected to the sealing seat 16. The output end of the electric slide 4 drives the transmission rod 5 to move upward. The transmission rod 5 drives the sealing seat 16 to move upward. The sealing seat 16 drives the connecting rod 17 and the crucible 18 to move upward, so that they are moved out of the combustion chamber 13, making it convenient for the user to put in the sample. The igniter 19 is used to ignite the sample and make it burn.

[0036] Working Principle: When using this combustion analysis instrument with a protective structure, the user first starts the electric slide 4. The output end of the electric slide 4 drives the transmission rod 5 to move upward, the transmission rod 5 drives the sealing seat 16 to move upward, and the sealing seat 16 drives the connecting rod 17 and the crucible 18 to move upward, moving them out of the combustion chamber 13 for easy sample placement. Then, the electric slide 4 drives the crucible 18 into the combustion chamber 13, and the igniter 19 is started to ignite the sample. The gas produced by combustion enters the analysis component 2, which detects it and calculates the content of elements such as carbon, hydrogen, nitrogen, and sulfur in the sample. The exhaust gas enters the purification component 3, where the acid gas neutralization section 33 removes SO2, HCl, and HF, and the catalytic oxidation layer 34 converts CO into CO2 and degrades NO. x The activated carbon adsorption layer 35 adsorbs residual organic matter, ozone and trace amounts of Hg to purify the exhaust gas before it is discharged, thus protecting the environment and solving the problem of pollution caused by direct exhaust gas discharge in existing technologies.
