Description

Technical Field

[0001] The utility model relates to the field of greenhouse gas monitoring, and more specifically to a greenhouse gas monitoring device. Background Art

[0002] A greenhouse gas detector is a device used to monitor atmospheric concentrations of greenhouse gases (such as carbon dioxide and methane). Based on principles such as spectral analysis and infrared absorption, it uses high-precision sensors and data processing systems to enable real-time monitoring and data analysis of greenhouse gas concentrations. This helps researchers understand greenhouse gas emissions and provides important support for environmental protection and climate change research.

[0003] When a greenhouse gas detector is working, it needs to draw in external air, that is, to draw in the gas to be tested. In order to ensure the accuracy of the detection, the external air must be as clean and low in humidity as possible. Existing greenhouse gas detectors have the function of filtering the air, but the filtering effect is limited. Large particles in the air will quickly block the air inlet of the greenhouse gas detector, causing poor air intake and affecting the detection effect. At the same time, most existing greenhouse gas detectors do not have a dehumidification function. When the air humidity is high, it is easy to cause distortion of the detection results of the greenhouse gas detector.

[0004] Therefore, how to provide a greenhouse gas monitoring device that can overcome the above problems is an issue that those skilled in the art urgently need to solve. Utility Model Content

[0028] Example

[0029] See attached Figure 1-6 Schematic diagram of the overall and partial structures of an embodiment of the present invention. The present invention specifically discloses a greenhouse gas monitoring device, including a greenhouse gas detector 1, a filter condensation assembly, and a frame 8; the filter condensation assembly and the greenhouse gas detector 1 are both mounted on the frame 8;

[0030] The filtration and condensation assembly includes a cyclone separator, a dust collection box 6 and a cover body 7. The cyclone separator includes a cylinder 2, an air inlet pipe 3, a cone cylinder 4 and an air outlet pipe 5. The cylinder 2 is arranged vertically and its upper end is closed and the lower end is open. An air inlet is provided on the side wall of the cylinder 2. The air inlet is located on one side of the axis of the cylinder 2, and the air intake direction of the air inlet is arranged along the tangential direction of the cylinder 2; one end of the air inlet pipe 3 is connected with the air inlet, and the other end of the air inlet pipe 3 is connected with the external atmosphere; both ends of the cone cylinder 4 are open and it is coaxially arranged with the cylinder 2, and the large-diameter end of the cone cylinder 4 is fixed and connected with the lower open end of the cylinder 2; the upper end of the cylinder 2 is opened and an air outlet pipe 5 is coaxially fixed. The air inlet is located between the upper inner wall of the cylinder 2 and the lower end of the air outlet pipe 5, and the upper end of the air outlet pipe 5 is connected with the air inlet end of the greenhouse gas detector 1. The greenhouse gas detector 1 is an existing technology. There are two ways to connect the outlet pipe 5 to the greenhouse gas detector 1. One is that the outlet pipe 5 is directly fixed and connected to the air inlet of the greenhouse gas detector 1. The other is to seal a cover on the greenhouse gas detector 1, and the cover has a hole and is connected to the outlet pipe 5. The cover also has a hole and is connected to the outlet end of the greenhouse gas detector 1 to ensure that the gas discharged from the greenhouse gas detector 1 will not enter the cover; the cyclone separator belongs to the existing technology. The cyclone separator relies on the rotational motion caused by the tangential introduction of the airflow to throw solid particles or droplets with large inertial centrifugal force to the outer wall to separate. This separation process is based on the mechanics of rotating flow, and separates solid particles or droplets in the mixed gas through strong centrifugal force.

[0031] The small-diameter end of the cone 4 is detachably fixed with a dust box 6 connected to its interior, and the impurities separated by the cyclone separator will fall into the dust box 6;

[0032] The outer wall sealing sleeve of the cone 4 is provided with a cover body 7. The cover body 7 and the outer wall of the cyclone separator jointly define an annular sealing cavity.

The cold water flowing out of the water outlet of the chiller will flow from the water inlet 70 enters the annular sealed cavity, and the water in the annular sealed cavity will flow out from the water outlet 71 to the chiller, and the chiller can circulate and cool the water in the annular sealed cavity; because the cold water will lower the temperature of the inner wall of the cone 4 after entering the annular sealed cavity, the moisture in the air in the cone 4 will condense on the inner wall of the cone 4, and the water vapor in the cone 4 will flow into the dust collecting box 6 after condensation; the cover body 7 is combined with the design of the cyclone separator to achieve filtration and dehumidification of the air, ensuring that the air entering the greenhouse gas detector 1 has low water content and few impurities, which meets the requirements of the greenhouse gas detector 1 for the humidity of the gas to be tested.

[0033] A rectangular mounting plate 80 is horizontally integrally formed on the frame 8 , and the greenhouse gas detector 1 is fixed on the mounting plate 80 , so that the greenhouse gas detector 1 can be reliably arranged.

[0034] A rectangular cavity 81 with an opening at the top is provided on the frame 8, and the cylinder 2, air inlet pipe 3, cone cylinder 4 and dust collecting box 6 are all arranged in the rectangular cavity 81, and the outer wall of the cylinder 2 is connected to the inner wall of the rectangular cavity 81 by a fixing block 9.

[0035] Thermal insulation foam panels 10 are evenly attached to the inner wall of the rectangular cavity 81 . The thermal insulation foam panels 10 can play a role in heat insulation, further reducing the heat exchange between the annular sealed cavity and the external environment of the rack 8 .

[0036] A rectangular mounting opening 82 is provided on the frame 8, which is connected to the rectangular cavity 81. The maximum outer diameter of the dust box 6 is smaller than the width of the mounting opening 82. A door panel 11 is hinged at the mounting opening 82 to seal it. This design facilitates the disassembly and removal of the dust box 6.

[0037] The open end of the dust collecting box 6 is provided with an external threaded tube 12 connected to its interior, and the inner wall of the small-diameter end of the cone cylinder 4 is provided with an internal thread adapted to the external threaded tube 12, and the external threaded tube 12 is screwed to the small-diameter end of the cone cylinder 4; the dust collecting box 6 and the cone cylinder 4 can be reliably fixed and connected, and the dust collecting box 6 is easy to disassemble and assemble.

[0038] More specifically, the apparatus further includes a vertically arranged connecting pipe 13, the lower end of which is fixed with an inserting pipe 14, the length of which is the same as that of the connecting pipe 13; the inserting pipe 14 fixed to one connecting pipe 13 can be tightly inserted into the other inserting pipe 14, and the end walls of the two connecting pipes 13 can be tightly abutted;

[0040] When the greenhouse gas monitoring device is in use, the greenhouse gas detector 1 extracts the gas in the cylinder 2 and the cone 4 through the outlet pipe 5, and the external air enters the cylinder 2 and the cone 4 in turn through the connecting pipe 13 and the air inlet pipe 3. When the external air passes through the cylinder 2, the cone 4 and the outlet pipe 5, the particulate matter in the air will be centrifugally separated; at the same time, the external chiller is working, and cold water flows in the annular sealed cavity. The moisture in the air in the cone 4 will condense on the inner wall of the cone 4 and flow down to the dust collecting box 6, thereby realizing the dehumidification of the air in the cone 4; the air that has completed dust removal and dehumidification finally enters the greenhouse gas detector 1.
