Description

Technical Field

[0001] This utility model relates to the field of hydrogen and oxygen gas content analysis technology, and specifically to a hydrogen and oxygen gas analysis device. Background Technology

[0002] A hydrogen and oxygen analyzer is an instrument used to measure the concentration of hydrogen and oxygen. It is commonly used in various fields, including gas detection, environmental monitoring, and industrial process control.

[0003] Chinese Patent CN208721654U discloses a hydrogen and oxygen gas analyzer, comprising a housing with a door panel on the front side and an observation port on the door panel. One outer wall of the housing has an air inlet, a flow bypass outlet, an analysis exhaust outlet, and a bypass exhaust outlet. The other outer wall of the housing has a first waterproof connector and a second waterproof connector. An air inlet pipe connected to the air inlet is installed inside the housing, and a dehydrator is installed on the air inlet pipe. The other end of the air inlet pipe is connected to a flow detection branch and a gas analysis branch. A straight-through regulating valve and a flow meter are sequentially installed on the flow detection branch. A three-way regulating valve and a filter are sequentially installed on the gas analysis branch. The other end of the gas analysis branch is connected to a first branch and a second branch via a three-way valve. The first branch is connected to a hydrogen analyzer, and the second branch is connected to an oxygen analyzer. This invention has the advantages of being easy to use, accurate in detection, and having multiple functions.

[0004] However, in the above technical solution, the gas analysis branch is connected to the first branch and the second branch via a T-junction. The first branch is connected to a hydrogen analyzer and the second branch is connected to an oxygen analyzer to analyze the gas. However, when this structure is used, the filter used to filter impurities is located in the middle of the pipeline. Before entering the filter, impurities may affect the upstream equipment in the pipeline. Secondly, filtering by only the dehydrator and the filter can only remove some impurities. The removal effect is poor for impurities such as corrosive gases and oil stains that are easy to affect the sensor. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a hydrogen and oxygen gas analysis device.

[0006] The technical solution of this utility model is as follows: A hydrogen and oxygen gas analysis device includes an analysis device body with an air inlet on one side and an air inlet pipe connected inside the air inlet. The analysis device body is equipped with a hydrogen analyzer and an oxygen analyzer connected to the air inlet pipe. A filter assembly is connected to the air inlet pipe and includes a multi-stage filter element, an oil removal filter, an activated carbon filter, and a chemical filter. The above components are arranged in series to form a composite filter structure to remove impurities in the air inlet pipe.

[0007] Preferably, the multi-stage filter consists of a pre-filter and a medium- and high-efficiency particulate filter connected in series, each adapted to particulate matter of different particle size ranges.

[0008] Preferably, a dehydrator is also connected to the air intake pipe, and the dehydrator is located upstream of the multi-stage filter.

[0009] Preferably, an installation cylinder is connected to the air intake pipe. The installation cylinder consists of a fixed frame and a movable frame. The fixed frame and the movable frame are detachably connected. The multi-stage filter element is placed in the cylindrical cavity formed by the fixed frame and the movable frame.

[0010] Preferably, the fixed frame is connected to a sealing ring that is compatible with the movable frame.

[0011] Preferably, the filter assembly further includes a filter cylinder, which consists of a fixed half-cylinder and a movable half-cylinder. Two baffles are connected to the fixed half-cylinder to divide the cylindrical cavity formed by the fixed half-cylinder and the movable half-cylinder into three filter chambers, which correspond to an oil removal filter, an activated carbon filter and a chemical filter, respectively.

[0012] Preferably, a sealing gasket is connected to the inner circumferential wall of the movable half-cylinder.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: In this invention, a composite filtration structure, including multi-stage filter elements, an oil removal filter, an activated carbon filter, and a chemical filter, is directly connected to the air inlet pipe. Located at the very front end of the gas entering the main body of the analysis equipment, this ensures that the gas undergoes high-efficiency filtration before entering any other components. This effectively prevents impurities from contaminating and damaging upstream equipment and pipelines, significantly improving the overall reliability and service life of the system. The composite filtration structure, composed of multi-stage filter elements (pre-filter + medium- and high-efficiency particulate filters), an oil removal filter, an activated carbon filter, and a chemical filter connected in series, can effectively remove various impurities such as particulate matter, oil mist, volatile organic compounds, and corrosive gases from the gas. This results in a more comprehensive filtration target, higher gas cleanliness, and significantly improved accuracy of gas analysis and the lifespan of the analyzer's sensors.

[0015] Example 1, as Figures 1-5 As shown, the present invention proposes a hydrogen and oxygen gas analysis device, comprising an analysis device body 1, an inlet pipe 2, a hydrogen analyzer 3, an oxygen analyzer 4, and a filter assembly. An inlet is provided on one side of the analysis device body 1, and the inlet pipe 2 is connected to the inlet. The hydrogen analyzer 3 and the oxygen analyzer 4, both connected to the inlet pipe 2, are installed inside the analysis device body 1. The analysis device body 1 also contains other devices for gas inlet / outlet or flow measurement, such as an outlet pipe, a three-way valve, and a flow meter, forming a complete flow path. The filter assembly is connected to the inlet pipe 2 and includes a multi-stage filter element 5, an oil removal filter 6, an activated carbon filter 7, and a chemical filter 8. These components are connected in series to form a composite filtration structure to remove impurities from the inlet pipe 2.

[0016] Example 2, as Figures 3-5 As shown, this utility model proposes a hydrogen and oxygen gas analysis device. Compared with Embodiment 1, this embodiment describes the detailed structure of the filter component. The filter assembly also includes a filter cartridge 16, which is bolted together with a fixed half-cylinder 17 and a movable half-cylinder 19. Two partitions 18 are connected to the fixed half-cylinder 17, dividing the cylindrical cavity formed by the fixed half-cylinder 17 and the movable half-cylinder 19 into three filter chambers. The partitions 18 have multiple through holes to allow gas to pass through. The three filter chambers correspond to the oil removal filter 6, the activated carbon filter 7, and the chemical filter 8, respectively. The oil removal filter 6, the activated carbon filter 7, and the chemical filter 8 have different service lives, so they are separated to prevent leakage from affecting each other. A sealing gasket 20 is connected to the inner circumferential wall of the movable half-cylinder 19; the sealing gasket 20 is made of rubber, which can enhance the sealing effect of the filter cylinder 16. The multi-stage filter element 5 consists of a primary particulate filter 9 and a medium- and high-efficiency particulate filter 10 connected in series. The two filters are adapted to particles of different particle sizes. The dual filtration can minimize the particulate matter in the air and prevent particulate matter from adhering to the inner wall of the pipe, valve or sensor, affecting its accuracy and causing wear. The intake pipe 2 is also connected to a dehydrator 11, which is located upstream of the multi-stage filter element 5. The dehydrator 11 is used to remove water vapor to prevent the subsequent filter media from getting damp or degrading in performance. An installation cylinder 12 is connected to the air intake pipe 2. The installation cylinder 12 consists of a fixed frame 13 and a movable frame 14. The fixed frame 13 and the movable frame 14 are detachably connected by bolts. The multi-stage filter element 5 is placed in the cylindrical cavity formed by the fixed frame 13 and the movable frame 14. The multi-stage filter element 5 consists of a primary particulate filter 9 and a medium- and high-efficiency particulate filter 10. Therefore, the two can be placed together directly in the installation cylinder 12 without being separated by a partition structure. A sealing ring 15 adapted to the movable frame 14 is connected to the fixed frame 13. The sealing ring 15 is made of rubber and is used to reduce the gaps generated when the fixed frame 13 and the movable frame 14 are connected by bolts, so as to prevent particulate matter from escaping and polluting the surrounding environment.

[0017] In summary, when this utility model is in use, the hydrogen-oxygen gas analyzer operates by introducing a hydrogen-oxygen mixture into the inlet pipe 2 through the inlet on one side of the main body 1 of the analyzer. The gas first flows through the filter assembly for pretreatment. The dehydrator 11 in the filter assembly first treats the gas, removing water vapor or moisture. The gas then enters the multi-stage filter element 5, which consists of a primary particulate filter 9 and a medium- and high-efficiency particulate filter 10 connected in series. The primary particulate filter 9 intercepts large-diameter particles in the gas, while the medium- and high-efficiency particulate filter 10 intercepts small-diameter particles, thereby removing particulate matter from the gas. After particulate matter filtration, the gas sequentially enters the three filter chambers in the filter cartridge 16, which correspond to the oil removal filter 6. The gas first passes through an oil removal filter 6 to remove oily substances; then through an activated carbon filter 7, which adsorbs volatile organic compounds and odors; finally, through a chemical filter 8, which adsorbs or neutralizes corrosive gases. After a series of filtrations, the purified gas enters the main body 1 of the analytical device and is connected to a hydrogen analyzer 3 and an oxygen analyzer 4. The hydrogen analyzer 3 measures and analyzes the hydrogen concentration in the gas, and the oxygen analyzer 4 measures and analyzes the oxygen concentration in the gas, achieving accurate detection of the hydrogen and oxygen concentrations in the hydrogen-oxygen mixture. The gas can be discharged through the outlet pipe of the main body 1 of the analytical device.

[0018] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
