Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, and in particular to a rapid sulfur analyzer for detecting the total sulfur content of coal. Background Technology

[0002] As an important energy resource, the accurate determination of the sulfur content of coal is of great significance for the rational utilization of coal, environmental protection, and industrial production control.

[0003] Currently, the commonly used method in the field of coal total sulfur content detection is to fully combust the coal, converting the sulfur elements into sulfide gases, and then indirectly determining the sulfur content of the coal by detecting the content of these gases. However, traditional detection instruments have revealed many drawbacks in this process. From the perspective of the combustion stage, due to instrument design flaws or unreasonable operating parameters, incomplete combustion of the coal often occurs. Incomplete combustion of the coal sample means that some sulfur elements cannot be converted into sulfide gases, resulting in a lower detected sulfide gas content than the actual amount that should be produced, thus leading to an underestimation of the total sulfur content in the test results.

[0004] To address the above issues, we propose a rapid sulfur analyzer for detecting the total sulfur content in coal. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid sulfur analyzer for detecting the total sulfur content of coal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rapid sulfur content analyzer for coal includes a coal combustion chamber with an auxiliary combustion assembly at its bottom. The auxiliary combustion assembly includes an oxygen input pipe and an argon input pipe, both fixedly connected and installed at the bottom of the coal combustion chamber. A first solenoid valve and a flow meter are fixedly installed on both the oxygen and argon input pipes. Arc igniters are equidistantly installed on the circumferential sidewall of the bottom of the coal combustion chamber. Several pads are fixedly installed at the bottom of the coal combustion chamber, with a tungsten wire alloy mesh placed on the upper side of each pad. An ash discharge pipe is fixedly connected and installed at the bottom of the coal combustion chamber, with a second solenoid valve fixedly installed on the ash discharge pipe.

[0008] Furthermore, the oxygen input pipe and the argon input pipe are located at the bottom of the tungsten wire alloy mesh. Several connecting rods are fixedly connected to the upper ports of the oxygen input pipe and the argon input pipe. Conical caps are fixedly installed on the upper ends of the connecting rods.

[0009] Furthermore, an exhaust cylinder is fixedly installed on the upper side wall of the coal combustion cylinder, and a third solenoid valve and an infrared sulfur detector are fixedly installed on the exhaust cylinder, with the detection end of the infrared sulfur detector extending to the inside of the exhaust cylinder.

[0010] Furthermore, a controller, a temperature sensor, and a pressure gauge are fixedly installed on the outer wall of the coal combustion cylinder, and the detection ends of the temperature sensor and the pressure gauge are connected to the inner side of the coal combustion cylinder.

[0011] Furthermore, the ash outlet pipe is located at the lowest point of the bottom of the coal combustion cylinder.

[0012] Furthermore, a top feeding assembly is provided at the upper end of the coal combustion cylinder. The top feeding assembly includes a top plate, which is screwed onto the upper end of the coal combustion cylinder. An electronic weighing pan is fixedly installed on the top plate.

[0016] This invention discloses a rapid sulfur analyzer for detecting the total sulfur content of coal. It incorporates an oxygen input pipe and an argon input pipe at the bottom of the coal combustion chamber, allowing for the simultaneous injection of a specific ratio of oxygen and argon during combustion. These are quantitatively controlled by a first solenoid valve and a flow meter, ensuring optimal combustion conditions for the coal. The coal combustion chamber is positioned above a tungsten wire alloy mesh at the bottom of the combustion chamber, ensuring the bottom of the coal is in contact with oxygen for complete combustion.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-5 A rapid sulfur content analyzer for coal includes a coal combustion chamber 1, with an auxiliary combustion assembly 5 at the bottom of the combustion chamber 1. The auxiliary combustion assembly 5 includes an oxygen input pipe 51 and an argon input pipe 52, both of which are fixedly connected and installed at the bottom of the combustion chamber 1. A first solenoid valve 53 and a flow meter 54 are fixedly installed on both the oxygen input pipe 51 and the argon input pipe 52. An arc igniter 57 is fixedly installed circumferentially on the side wall at the bottom of the combustion chamber 1. Several pads 10 are fixedly installed at the bottom of the combustion chamber 1, with a tungsten wire alloy mesh 510 placed on the upper side of each pad 10. An ash discharge pipe 58 is fixedly connected and installed at the bottom of the combustion chamber 1, with a second solenoid valve 59 fixedly installed on the ash discharge pipe 58.

[0025] In this method, a top feeding assembly 9 is provided at the upper end of the coal combustion cylinder 1. The top feeding assembly 9 includes a top plate 91, which is screwed onto the upper end of the coal combustion cylinder 1. An electronic weighing pan 92 is fixedly installed on the top plate 91. A feeding pipe 93 is fixedly installed at the center of the top plate 91. A fourth solenoid valve 94 is fixedly installed on the outside of the feeding pipe 93. A cone 95 is fixedly connected to the upper end of the feeding pipe 93. A drive motor 96 is fixedly installed inside the cone 95. A rotating shaft 97 is fixedly installed below the output end of the drive motor 96. Several blades 98 are fixedly installed on the outer wall of the rotating shaft 97.

[0026] With the above-mentioned setup, the electronic weighing pan 92 is used to weigh the coal. After weighing, the coal is put into the cone 95, and the drive motor 96 is started simultaneously to drive the rotating shaft 97 to rotate, which in turn drives the blade 98 to rotate at the bottom of the cone to crush the coal. After the coal is crushed, the fourth solenoid valve 94 is opened, and the subsequently crushed coal falls through the feeding pipe 93 onto the upper side of the tungsten wire alloy pad 510 at the bottom of the coal combustion cylinder 1, so that the coal to be tested is separated and crushed into several small pieces of coal, which facilitates the complete combustion of the coal. In addition, the weighing data is recorded in the controller 2, which is then used to calculate the sulfide content in the coal.

[0027] In this configuration, oxygen input pipe 51 and argon input pipe 52 are located at the bottom of tungsten wire alloy mesh 510. Several connecting rods 55 are fixedly connected to the upper ports of oxygen input pipe 51 and argon input pipe 52. Conical caps 56 are fixedly installed on the upper ends of the connecting rods 55. Metal dustproof mesh is embedded inside the upper ports of oxygen input pipe 51 and argon input pipe 52.

[0028] The cone cap 56, as described above, provides a protective cover for the upper ports of the oxygen input pipe 51 and the argon input pipe 52, preventing the fly ash from falling onto the metal dust screen after combustion. The metal dust screen also prevents fly ash from falling into the oxygen input pipe 51 and the argon input pipe 52.

[0029] In this method, an exhaust cylinder 6 is fixedly installed on the upper side wall of the coal combustion cylinder 1. A third solenoid valve 7 and an infrared sulfur detector 8 are fixedly installed on the exhaust cylinder 6. The detection end of the infrared sulfur detector 8 extends to the inside of the exhaust cylinder 6.

[0030] With the above setup, the infrared sulfur analyzer 8 monitors sulfides based on the absorption characteristics of gas molecules to infrared light of specific wavelengths. Combined with spectral analysis technology, it achieves qualitative and quantitative detection of sulfides (such as SO2, H2S, etc.). It is a common detection instrument and will not be elaborated further here.

[0031] In this method, a controller 2, a temperature sensor 3, and a pressure gauge 4 are fixedly installed on the outer wall of the coal combustion cylinder 1. The detection ends of the temperature sensor 3 and the pressure gauge 4 are connected to the inner side of the coal combustion cylinder 1.

[0032] With the above configuration, temperature sensor 3 and pressure gauge 4 are used to detect the temperature and pressure in the coal combustion chamber 1, respectively.

[0033] In this configuration, the ash discharge pipe 58 is located at the lowest point of the bottom of the coal combustion cylinder 1.

[0034] The above-mentioned configuration facilitates the discharge of fly ash from the ash outlet pipe 58 after combustion.

[0035] In this method, a high-temperature resistant sealing gasket is provided at the bottom of the top plate 91 and the upper side of the coal combustion cylinder 1 where they are bolted together.

[0036] The above-mentioned setup ensures the airtightness of the coal combustion chamber 1.

[0037] The working principle of the rapid sulfur content analyzer for coal provided by this utility model is as follows:

[0038] Coal preparation and feeding: The coal to be tested is placed on the electronic weighing pan 92 on the top plate 91. The electronic weighing pan 92 accurately weighs the coal and transmits the data to the controller 2. Subsequently, the coal is fed into the cone 95, the drive motor 96 starts, driving the rotating shaft 97 and blades 98 to rotate, thus crushing the coal. After crushing, the coal falls through the feeding pipe 93 onto the upper side of the tungsten wire alloy mesh 510 at the bottom of the coal combustion cylinder 1 after the fourth solenoid valve 94 is opened.

[0039] Assisted combustion process: After the coal is in place, oxygen input pipe 51 and argon input pipe 52, under the control of the first solenoid valve 53 and flow meter 54, inject oxygen and argon into the coal combustion chamber 1 in a specific ratio. Simultaneously, the arc igniters 57, equidistantly distributed around the bottom sidewall of the coal combustion chamber 1, are activated synchronously, rapidly igniting the coal and accelerating the combustion process. The tungsten wire alloy mesh 510 ensures that the bottom of the coal is in full contact with oxygen, guaranteeing complete combustion.

[0040] Gas detection: The sulfur-containing gas produced by coal combustion rises to the gas outlet 6 on the upper side wall of the coal combustion cylinder 1. The infrared sulfur analyzer 8 on the gas outlet 6 uses the absorption characteristics of gas molecules to infrared light of a specific wavelength and spectral analysis technology to perform qualitative and quantitative detection of sulfides and accurately determine the sulfide content.

[0041] Environmental monitoring and control: During coal combustion, temperature sensor 3 and pressure gauge 4 on the outer wall of the coal combustion cylinder 1 monitor the temperature and pressure inside the cylinder in real time and transmit the data to controller 2. Controller 2 monitors and adjusts the combustion process according to the set parameters to ensure a stable combustion environment.

[0042] Ash disposal: After the coal is burned, open the second solenoid valve 59 on the ash discharge pipe 58. Since the ash discharge pipe 58 is located at the lowest point of the coal combustion cylinder 1, the fly ash produced by the combustion is discharged smoothly.

[0043] Data calculation and result output: The controller 2 combines the coal weight data recorded by the electronic weighing pan 92 and the sulfide content data detected by the infrared sulfur analyzer 8 to calculate the total sulfur content of the coal and output the final test result.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
