[0019] Beneficial effects of the utility model:

[0020] 1. By cooling and dehumidifying the combustion gas during the analysis process, moisture interference on the test results is effectively eliminated, thereby improving the accuracy of carbon and sulfur analysis. This ensures that the infrared analyzer operates under more stable conditions, avoiding the impact of excessive moisture content in the gas on the infrared absorption signal strength, thereby improving the detection accuracy of carbon and sulfur components.

[0021] 2. A highly efficient cooling and dehumidification component is designed. Heat exchange is achieved through spiral tubes in heat exchange tanks A and B, effectively reducing the temperature and removing moisture from the gas as it passes through the dehumidification tray. Furthermore, the agitation mechanism in the dehumidification tray absorbs moisture from the gas, which is then dried and dehumidified during the subsequent heating process. This ensures a more stable gas environment during carbon and sulfur analysis.

[0022] 3. The combustion assembly, through the coordination of a heating furnace, a heat-insulating enclosure, and a ring-shaped gas supply pipe system, ensures stable and complete combustion of sulfur concentrate. After combustion, the gas undergoes a pretreatment phase to control temperature and humidity, ensuring more accurate subsequent gas composition analysis. In particular, combustion gases are promptly discharged to heat exchange tank A via an on / off valve, further optimizing airflow stability and flow path.

[0023] 4. In the dehumidification tray, the agitation mechanism and absorbent filler work together to ensure efficient water absorption and recycling. During the gas processing process, the fan and air heater work together to not only effectively improve dehumidification efficiency but also further dry the absorbent filler through temperature control, ensuring long-term stable operation of the equipment. This sophisticated dehumidification and airflow control technology enables the equipment to maintain excellent performance even in high-humidity environments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-7 The infrared carbon-sulfur analysis device for sulfur concentrate inspection includes a chassis 1 and a combustion component, a cooling and dehumidification component, a carbon infrared detection tank 4, and a sulfur infrared detection tank 5 assembled in the chassis 1 and kept connected in sequence.

[0034] The cooling and dehumidification components include a heat exchange tank A31, a heat exchange tank B32, a dehumidification disk 33, a fan 34, an air heater 35, and a stirring mechanism. The heat exchange tank A31 and the heat exchange tank B32 are respectively equipped with a spiral tube A311 and a spiral tube B321. The spiral tube A311 and the spiral tube B321 are connected end to end through a connecting tube 37 to form a closed passage. The connecting tube 37 is equipped with a pressure pump 371. The closed passage is filled with a heat exchange medium. The dehumidification disk 33 is filled with a water-absorbing filler. The stirring mechanism is assembled in the dehumidification disk 33.

[0035] The gas components produced by the complete combustion of sulfur concentrate by the combustion assembly pass through the heat exchange tank A31, dehumidification disk 33, carbon infrared detection tank 4, and sulfur infrared detection tank 5 in sequence before being discharged. The external air extracted by the fan 34 passes through the heat exchange tank B32, air heater 35, and dehumidification disk 33 in sequence before being discharged.

[0036] When testing the carbon and sulfur components of sulfur concentrate, a specific amount of sulfur concentrate is loaded into the combustion assembly and fully burned in an oxygen atmosphere to form a gas component. The gas component passes through the heat exchange tank A31 and is fully heat-exchanged with the heat exchange medium in the spiral tube A311 therein, and the temperature drops. The gas component continues to pass into the dehumidification disk 33 to adsorb the moisture contained therein by the water-absorbing filler. The gas component after cooling and dehumidification treatment is sequentially passed into the carbon infrared detection tank 4 and the sulfur infrared detection tank 5, and the total amount of carbon dioxide and sulfur dioxide is analyzed and detected respectively. Then, the proportion of carbon and sulfur in the sulfur concentrate can be calculated based on the total amount of sulfur concentrate burned.

[0037] The carbon and sulfur content of the gas components can be tested after being cooled and dehumidified, which can effectively improve the detection accuracy.

[0038] The heat exchange medium with increased temperature in the spiral tube A311 enters the spiral tube B321 in the heat exchange tank B32. The external natural air drawn by the fan 34 enters the heat exchange tank B32 and is fully heated by the heat exchange medium in the spiral tube B321, and its temperature increases. It is further heated by the air heater 35 and then input into the dehumidification disk 33 from the other direction to dry and dehumidify the water-absorbing filler adsorbed with water vapor in the dehumidification disk 33. The treated gas is discharged outward together with the water vapor.

[0039] In order to ensure that the combustion component, the cooling and dehumidification component, the carbon infrared detection tank 4 and the sulfur infrared detection tank 5 can be stably installed in the chassis 1 and to facilitate the operation of the equipment, the following technical solutions are provided.

The combustion component is assembled in the lower chamber 12, and the cooling and dehumidification component, the carbon infrared detection tank 4, and the sulfur infrared detection tank 5 are assembled in the upper chamber 11.

[0041] The combustion assembly is designed to be separated from the cooling and dehumidification assembly, carbon infrared detection tank 4, and sulfur infrared detection tank 5. The lower chamber door 14 can be opened separately to replace different types of sulfur concentrates and perform carbon-sulfur analysis on the combustion assembly. The cooling and dehumidification assembly, carbon infrared detection tank 4, and sulfur infrared detection tank 5 assembled in the upper chamber 11 do not require frequent replacement and maintenance.

[0042] In order to ensure that the combustion assembly can be stably installed in the lower chamber 12 and realize stable and sufficient combustion of the added sulfur concentrate, and to ensure that the combustion assembly can be stably connected to the heat exchange tank A31, the following technical solution is provided.

[0043] The combustion assembly includes a heating furnace 21 and an insulating sealing cover 22 assembled on the heating furnace 21. A tray is fixedly installed in the heating furnace 21, and the insulating sealing cover 22 is arranged on the periphery of the tray. An annular air supply pipe 221 is fixedly connected to the outside of the insulating sealing cover 22. The annular air supply pipe 221 is equipped with multiple groups of air nozzles 222 that are evenly distributed and extend to the inside of the insulating sealing cover 22. The annular air supply pipe 221 is connected to an air receiving pipe 223, and the air receiving pipe 223 extends to the outside of the chassis 1.

[0044] The top of the heat-insulating sealing cover 22 is connected to the bottom end of the heat exchange tank through a connecting pipe 224 , and a switch valve 225 is installed on the connecting pipe 224 .

[0045] The tray can stably receive the sulfur concentrate and fully burn the sulfur concentrate through the heating furnace 21, and transport oxygen to the heat-insulating sealing cover 22 through the air pipe 223, the annular air supply pipe 221 and the air nozzle 222 to achieve full combustion of the sulfur concentrate in the oxygen atmosphere.

[0046] After the sulfur concentrate is fully burned, the switch valve 225 is opened and inert gas is input into the gas connecting pipe 223 to transport all the gas components generated by the combustion along the connecting pipe 224 to the heat exchange tank A31.

[0047] In order to ensure that the dehumidification disk 33 can be docked with the heat exchange tank A31 and the heat exchange tank B32, and to ensure that the dehumidification disk 33 can complete the dehumidification of gas components and the drying of water-absorbing fillers, the following technical solutions are provided.

[0048] An assembly cover 331 is fixed to the top of the dehumidification disk 33, and the assembly cover 331 is connected to the docking port A332 and the docking port B333.

[0049] Intercepting mesh plates 336 are installed at the positions of the docking ports A332, B333, a334 and b335. The intercepting mesh plates 336 can prevent the water-absorbing filler from leaking out without affecting the normal airflow in and out of the dehumidification tray 33.

[0050] The gas components generated by burning sulfur concentrate enter the dehumidification disk 33 after being cooled, and the water in them is absorbed by the water-absorbing filler and transported outward along the upper docking port A332 and the exhaust pipe A381. They pass through the carbon infrared detection tank 4 and the sulfur infrared detection tank 5 in sequence for detection of carbon and sulfur content and are then discharged. The discharged gas components can also be connected to an air purifier for purification.

[0051] The water-absorbing filler that absorbs moisture is driven by the stirring mechanism in the dehumidification disk 33. When it reaches the position of the docking port B333 and the docking port b335, the air extracted by the fan 34 is heated by the heat exchange tank B32 and the air heater 35 and then transported to the dehumidification disk 33 through the docking port B333 to dry out the moisture in the water-absorbing filler and finally discharged to the outside through the exhaust pipe B383.

[0054] When the driving motor 361 is working, it can drive the mounting shaft 362 and the stirring plate 363 fixed to the driving shaft to operate stably through the combination of the driving bevel gear 364 and the transmission bevel gear 365. The stirring plate 363 drives the water-absorbing filler in the dehumidification disk 33 to operate stably, so as to realize the transfer of the water-absorbing filler to different workstations of the dehumidification disk 33.
