Description

Technical Field

[0001] This utility model belongs to the technical field of gas analyzers, and in particular relates to a temperature control component for a carbon neutralization gas analyzer. Background Technology

[0002] Carbon neutral gas analyzers are key devices for monitoring and analyzing greenhouse gas emissions, helping governments, businesses, and research institutions achieve carbon neutrality goals. These instruments primarily measure the concentrations of greenhouse gases such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and sulfur hexafluoride (SF6), and track their emission sources. Through accurate data acquisition and analysis, carbon neutral gas analyzers can provide reliable evidence for carbon accounting, emission reduction strategy formulation, and carbon neutrality certification. The temperature control component of a carbon neutral gas analyzer is used to stably set the gas analyzer, ensuring that both the analyzer and the gas temperature are relatively constant. However, the temperature control component of a carbon neutral gas analyzer still has the following drawbacks in practical use:

[0003] The temperature control component of the carbon neutrality gas analyzer needs to keep the analyzer warm during operation, but the analyzer also needs to be removed to record the measured data. The overall insulation and disassembly of the temperature control component of the analyzer require fastening and installation, which makes the temperature control and insulation of the temperature control component inconvenient.

[0004] Secondly, the analyzer needs to deliver the measured gas at a constant temperature into the analyzer and remove the waste gas generated in the analyzer. Therefore, in this process, the gas with a stable temperature needs to be delivered to the air inlet of the analyzer. It is not convenient to obtain a continuous constant temperature airflow during operation. Utility Model Content

[0005] The purpose of this invention is to provide a temperature control component for a carbon neutrality gas analyzer. By setting up an outer protective box, an insulation box, and a fixing cylinder, it solves the problems of inconvenient temperature control and insulation of the temperature control component in the carbon neutrality gas analyzer, and the inconvenience of obtaining a continuous constant temperature airflow.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a temperature control component for a carbon neutrality gas analyzer, comprising an outer protective box, an insulation box, and a fixed cylinder. The insulation box is movably connected inside the outer protective box, and the fixed cylinder is fixedly connected to the top of the outer protective box. A spiral tube is installed inside the fixed cylinder. An internal air inlet is provided on the top of the insulation box corresponding to the fixed cylinder, and an internal exhaust port is provided on the bottom of the insulation box. The internal air inlet and the internal exhaust port are offset from each other when viewed from above. An air pump is fixedly connected to the top of the fixed cylinder, and an air inlet sleeve is fixedly connected to the top of the air pump. During operation, the insulation box is housed within the outer protective box, and the fixed cylinder is supported on it. The insulation box keeps the gas being measured at a constant temperature, while simultaneously maintaining the temperature of the gas analyzer. The gas being measured is then transported to the insulation box through the fixed cylinder after heat exchange.

[0008] Furthermore, support plates are fixed to the two short sides of the bottom of the outer protective box. An external air inlet is opened on the top of the outer protective box corresponding to the internal air inlet. An external exhaust hole is opened on the bottom of the outer protective box corresponding to the internal exhaust hole. The bottom end of the fixed cylinder is fixed to the top of the outer protective box outside the external air inlet. The support plate on the outer protective box is supported on the ground. The external air inlet transports the fixed cylinder into it, and the external exhaust hole discharges the gas to be measured.

[0009] Furthermore, a baffle is fixed to one end of the insulated box, and one side of the insulated box is open. The baffle is located outside the outer protective box, restricting the positions of the insulated box and the outer protective box, and moving the baffle when it is pulled.

[0010] Furthermore, the end of the insulation box away from the baffle is open, and an inner insulation sheet is fixed on the inner wall of the outer protective box opposite the opening of the insulation box. When the insulation box is working, its open end is insulated by the inner insulation sheet inside the outer protective box.

[0011] Furthermore, two parallel mounting rails are fixed at the bottom of the insulated box. The mounting rails are positioned close to the fixed cylinder, and the gas analyzer is mounted on the mounting rails inside the insulated box.

[0012] Furthermore, the input end of the spiral tube is fixedly connected to a water supply pipe, and the output end of the spiral tube is fixedly connected to a return water pipe. Both the water supply pipe and the return water pipe pass through the periphery of the fixed cylinder. The water supply pipe delivers the heat exchange water into the spiral tube and then delivers it to the return water pipe for output.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of inconvenient temperature control and insulation for the temperature control component of a carbon neutrality gas analyzer by setting up an outer protective box and an insulation box. By pulling the baffle, the insulation box is pulled out of the outer protective box, and the gas analyzer is then installed on the mounting track inside the insulation box. The opening of the insulation box is then aligned with the opening of the outer protective box, and the box is slid until it contacts the inner insulation sheet. The gas analyzer is then installed inside the outer protective box, where it is insulated, effectively maintaining a suitable temperature between the gas analyzer and the gas. This makes temperature control and insulation for the temperature control component of the carbon neutrality gas analyzer much more convenient.

[0015] This invention solves the problem of the inconvenience of obtaining a continuous, constant-temperature airflow in carbon neutrality gas analyzers by setting up an outer protective box, an insulation box, and a fixed cylinder. The exhaust fan draws the gas to be measured from the gas inlet sleeve into the exhaust fan, then blows it into the fixed cylinder. Subsequently, heat exchange water is transported through the water supply pipe to the spiral tube, and then through the spiral tube to the return water pipe for recirculation. When the heat exchange water passes through the spiral tube, the gas to be measured undergoes heat exchange in the spiral tube and is transported to the external air inlet on the outer protective box. Then, it is transported to the outer protective box through the internal air inlet on the insulation box, and then through the internal exhaust port on the insulation box to the external exhaust port on the outer protective box. Finally, it is discharged into the exhaust equipment through the external exhaust port, so that the temperature in the insulation box is maintained at a suitable level, making it more convenient for the carbon neutrality gas analyzer to obtain a continuous, constant-temperature airflow.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-5 This utility model relates to a temperature control component for a carbon neutrality gas analyzer, comprising an outer protective box 1, an insulation box 2, and a fixed cylinder 3. The insulation box 2 is movably connected inside the outer protective box 1. During operation, the outer protective box 1 protects the insulation box 2, which in turn contains, protects, and keeps the gas analyzer at a constant temperature. The top of the outer protective box 1 is fixedly connected to the fixed cylinder 3, which supplies air to the insulation box 2. A spiral tube 302 is installed inside the fixed cylinder 3. When the spiral tube 302 passes through the heat exchange water, the gas to be tested in the fixed cylinder 3 exchanges heat with the heat exchange water, allowing the gas to be heated to a specified temperature. An internal air inlet 201 is provided on the top of the insulation box 2, corresponding to the fixed cylinder 3. The gas to be tested is delivered into the external air inlet 101 on the outer protective box 1. The bottom of the insulation box 2 is provided with an internal exhaust port 202. The gas to be tested is discharged from the internal exhaust port 202 on the insulation box 2 into the external exhaust port 102 on the outer protective box 1. The internal air inlet 201 and the internal exhaust port 202 are staggered from a top view to ensure that the gas to be tested flows fully in the insulation box 2. The top of the fixed cylinder 3 is fixedly connected to the vacuum pump 304. The top of the vacuum pump 304 is fixedly connected to the air inlet sleeve 4. The top of the air inlet sleeve 4 is connected to the equipment for delivering the gas to be tested. The gas to be tested is delivered to the vacuum pump 304. After being drawn in by the vacuum pump 304, it is delivered to the fixed cylinder 3 and then delivered to the external air inlet 101 on the outer protective box 1.

[0026] Specifically, support plates 104 are fixed to the two short sides of the bottom of the outer protective box 1. An external air inlet 101 is opened on the top of the outer protective box 1 corresponding to the internal air inlet 201. An external exhaust 102 is opened on the bottom of the outer protective box 1 corresponding to the internal exhaust 202. The bottom end of the fixing cylinder 3 is fixed to the top of the outer protective box 1 outside the external air inlet 101. The external exhaust 102 at the bottom of the outer protective box 1 connects to the exhaust equipment. The support plates 104 support the outer protective box 1 on the exhaust equipment.

[0027] Furthermore, a baffle 204 is fixed to one end of the insulated box 2, and one side of the insulated box 2 is open. The baffle 204 is located outside the outer protective box 1, and the baffle 204 on the insulated box 2 restricts its position relative to the outer protective box 1.

[0028] Furthermore, the end of the insulation box 2 away from the baffle 204 is open, and an inner insulation sheet 103 is fixed on the inner wall of the outer protective box 1 opposite to the opening of the insulation box 2. The inner insulation sheet 103 inside the insulation box 2 closes the opening end of the insulation box 2.

[0029] Furthermore, two parallel mounting rails 203 are fixed at the bottom of the insulated box 2. The mounting rails 203 are located close to the fixed cylinder 3 and are used to mount the carbon neutralization gas analyzer inside the insulated box 2.

[0030] The operation process of this embodiment is as follows: During operation, first pull the baffle 204 to pull the insulation box 2 out of the outer protective box 1, then install the gas analyzer on the mounting track 203 inside the insulation box 2, then align the opening end of the insulation box 2 with the opening end of the outer protective box 1, and then slide it to contact the inner insulation sheet 103, so that the gas analyzer can be installed in the outer protective box 1. The gas analyzer can be kept warm in the insulation box 2, which can effectively keep the gas analyzer and the gas at a suitable temperature. Specific Implementation Example 2

[0031] Please see Figure 1-5 Based on the first specific embodiment, the input end of the spiral tube 302 is fixedly connected to a water supply pipe 301, and the output end of the spiral tube 302 is fixedly connected to a return water pipe 303. Both the water supply pipe 301 and the return water pipe 303 pass through the periphery of the fixed cylinder 3. The end of the water supply pipe 301 away from the spiral tube 302 is connected to the equipment for transporting heat exchange water, and the end of the return water pipe 303 away from the spiral tube 302 is connected to the pipeline for returning heat exchange water.

[0032] The operation process of this embodiment is as follows: During operation, the vacuum pump 304 delivers the gas to be tested from the gas pipeline connected to the air inlet sleeve 4 into the vacuum pump 304, and then blows it into the fixed cylinder 3. At the same time, the water supply pipe 301 delivers heat exchange water to the spiral tube 302, and then delivers it to the return water pipe 303 for recirculation through the spiral tube 302. When the heat exchange water passes through the spiral tube 302, the gas to be tested undergoes heat exchange through the spiral tube 302 and is delivered to the external air inlet 101 on the outer protective box 1. Then, it is delivered to the outer protective box 1 through the internal air inlet 201 on the insulation box 2, and then to the internal exhaust 202 on the insulation box 2 and finally to the external exhaust 102 on the outer protective box 1. The gas is then discharged into the exhaust equipment through the external exhaust 102, so that the temperature in the insulation box 2 is maintained at a suitable level.
