Description
Technical Field
[0001] The utility model relates to the technical field of atmospheric sulfide analysis, in particular to an atmospheric sulfide analysis device. Background Art
[0002] Atmospheric sulfides mainly include sulfur dioxide, sulfur trioxide, sulfates and organic sulfides such as carbonyl sulfide and dimethyl sulfide. Their presence in the atmosphere has an important impact on environmental quality and human life. The sulfides in the current atmosphere mainly come from the combustion of mineral fuels, the smelting of sulfur-containing ores and industrial production processes such as oil refining, papermaking, and chemicals. In the process of urbanization, large amounts of exhaust gas and industrial waste gas emissions have become the main source of air pollution.
[0003] Atmospheric sulfide analysis devices are used to detect and analyze sulfide in the atmosphere. These devices are of great significance for monitoring environmental pollution, industrial emissions, urban planning, and meteorological research. Common equipment includes online sulfide monitors, gas chromatography analyzers, sulfide analyzers, and analysis systems based on ultraviolet fluorescence. These devices can help scientists understand the distribution and transformation process of sulfide in the environment, as well as its potential impact on ecosystems and human health.
[0004] In existing technical solutions, a gas chromatograph is usually used for detection and analysis. The collected gas is sent to a vaporization chamber and carried into a chromatographic column by a carrier gas. The chromatographic column then separates the gas. Finally, the detector converts the separated sample components into electrical signals. These signals are amplified and transmitted to a recorder or data processing system. However, the sulfides collected in the atmosphere include not only gaseous forms but also solid and liquid particulate matter. When the gas is separated in the chromatographic column, the particulate matter may block the inlet and outlet of the chromatographic column, thereby affecting the separation effect, reducing the column efficiency, and causing damage to the entire equipment.

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.
[0026] See also Figures 1 to 3, the utility model provides a technical solution:
[0027] An atmospheric sulfide analysis device includes a body 1, a filter assembly 4 is provided on the left side of the upper end of the body 1, and the filter assembly 4 includes a box body 41 fixedly connected to the left side of the upper end of the body 1, and the inner upper end and the front and rear ends of the box body 41 are provided with a guide groove 411, and the inner lower end of the box body 41 is provided with a cavity 42, and the cavity 42 is located below the guide groove 411. The upper end of the box body 41 is provided with an inlet groove 412, and the inner upper end of the cavity 42 is movably connected to a baffle 43, and a circular shaft 431 is movably connected between the baffle 43 and the upper end of the cavity 42, and a torsion spring 432 is movably connected between the circular shaft 431 and the baffle 43, and the left end of the box body 41 is fixedly connected There is a drain pipe 44, the front end of the body 1 is movably connected to the sealing door 12, and a rotating shaft 11 is movably connected between the body 1 and the sealing door 12. The right end of the body 1 is fixedly connected to the control system 13, the internal rear end of the body 1 is fixedly connected to the fixed wheel 2, the outside of the fixed wheel 2 is fixedly connected to the chromatographic column 21, the upper left end of the chromatographic column 21 is fixedly connected to the catheter 3, the upper end of the catheter 3 is movably connected to the pre-aiming tube 31, and a silicone pad 32 is movably connected between the catheter 3 and the pre-aiming tube 31. The elastic force of the circular shaft 431 is greater than the gravity exerted on the baffle 43, and the baffle 43 always remains horizontal. The baffle 43 can swing from 0 to 30 degrees through the circular shaft 431.
[0028] By adopting the above technical solution, before analyzing the atmospheric sulfide, it is first necessary to inject a neutralizer into the guide groove 411 through the inlet groove 412, and the neutralizer then flows along the guide groove 411 to the inside of the cavity 42. Secondly, it is necessary to install a chromatographic column 21 on the outside of the fixed wheel 2, and install the left end of the chromatographic column 21 to the inside of the conduit 3 that passes through the upper end of the body 1. Then, the conduit 3 at one end of the collected sample gas bag is installed to the outside of the air inlet pipe 54. The detection gas is squeezed into the air inlet pipe 54 by squeezing the gas bag, and then enters the cavity 42 through the cylinder 52. The density of the gas entering the cavity 42 is less than the density of the neutralizer, so that the detection gas stays at the upper end of the cavity 42. The detection gas staying at the upper end of the cavity 42 moves toward the right end along the inclined slope of the upper end of the cavity 42. By continuously injecting gas into the cavity 42, the gas When it moves to the lower end of the baffle 43, when the buoyancy of the accumulated gas is greater than the elastic force of the torsion spring 432 on the baffle 43, the baffle 43 is flipped upward by the circular shaft 431, so that the baffle 43 is tilted upward, and the gas moves upward along the lower end of the baffle 43, and finally enters the inside of the conduit 3, and the neutralizer inside the cavity 42 can react with other substances in the gas, so that the gas entering the inside of the conduit 3 contains only sulfide, and the particulate impurities attached to the detection gas have a density less than that of the neutralizer and float on the water surface, and have a density greater than that of the neutralizer and sink to the bottom of the neutralizer, thereby filtering the detected gas, entering the chromatographic column 21 through the conduit 3 for separation, and entering the control system 13 through the right end of the chromatographic column 21 for analysis, thereby preventing the particles and other substances in the atmosphere from causing harm to the chromatographic column 21, and thus affecting the data of gas detection analysis.
[0029] Specifically, such as Figure 3 and Figure 4 As shown, a speed control component 5 is provided at the left end of the box body 41, and the speed control component 5 includes a connecting pipe 51 fixedly connected to the left end of the box body 41, the upper end of the connecting pipe 51 is fixedly connected to a cylinder 52, the upper end of the cylinder 52 is fixedly connected to an air intake pipe 54, a groove 521 is provided inside the cylinder 52, the lower end of the inner part of the cylinder 52 is fixedly connected to a spring 53, and the upper end of the spring 53 is fixedly connected to a check ball 531, the upper and lower ends of the cavity 42 are both inclined, and the multiple guide grooves 411 all penetrate into the interior of the cavity 42, the conduit 3 and the drain pipe 44 all penetrate into the interior of the cavity 42, the elastic force of the spring 53 is greater than the gravity on the check ball 531, and the check ball 531 slides and fits inside the groove 521.
[0030] By adopting the above technical solution, the catheter 3 at one end of the sample gas bag is installed to the outside of the air inlet pipe 54, and the test gas is squeezed into the air inlet pipe 54 by squeezing the gas bag. When the squeezing force is too large, the gas inside the air inlet pipe 54 increases continuously, causing the pressure to increase, so that the elastic force on the spring 53 is less than the gravity and upper end pressure on the stop ball 531, so that the stop ball 531 moves downward continuously, blocking the upper end of the connecting pipe 51. At this time, the gas cannot be transported normally. When the force for squeezing the gas bag is too small, the stop ball 531 It is unable to move downward, and thus the gas cannot pass through the cylinder 52 into the interior of the connecting tube 51. When the air bag is squeezed with a uniform force, the stop ball 531 moves downward without contacting the inner upper end of the connecting tube 51. By continuously squeezing the air bag, the gas passes through the groove 521 and the gap between the connecting tube 51 and the cylinder 52 into the interior of the connecting tube 51, and then subsequent work is carried out, thereby avoiding the gas passing through the chromatographic column 21 too quickly, causing a decrease in separation efficiency, and thus achieving good separation effect and detection accuracy while ensuring analysis efficiency.
[0031] Working principle: First, install the catheter 3 at one end of the sample gas bag to the outside of the air inlet pipe 54, squeeze the gas bag to squeeze the test gas into the air inlet pipe 54, and then enter the cavity 42 through the cylinder 52. The density of the gas entering the cavity 42 is less than the density of the neutralizer, so that the test gas stays at the upper end of the cavity 42. The test gas staying at the upper end of the cavity 42 moves toward the right end along the inclined slope of the upper end of the cavity 42. By continuously injecting gas into the cavity 42, the gas moves to the lower end of the baffle 43. When the buoyancy of the accumulated gas is greater than the elastic force of the torsion spring 432 on the baffle 43, the baffle 43 is flipped upward through the circular shaft 431. The baffle 43 is tilted upward, and the gas moves upward along the lower end of the baffle 43 and finally enters the inside of the conduit 3. The neutralizer inside the cavity 42 can react with other substances in the gas, so that the gas entering the inside of the conduit 3 contains only sulfide, and the particulate impurities attached to the detection gas float on the water surface if the density is less than that of the neutralizer, and sink to the bottom of the neutralizer if the density is greater than that of the neutralizer, thereby filtering the detection gas, entering the chromatographic column 21 through the conduit 3 for separation, and entering the control system 13 through the right end of the chromatographic column 21 for analysis, thereby preventing the particles and other substances in the atmosphere from causing harm to the chromatographic column 21, and thus affecting the data of gas detection analysis.
