Description

Technical Field

[0001] This utility model relates to the field of monitoring instrument technology, specifically a gas leak monitoring device. Background Technology

[0002] Monitoring instruments are devices used to measure, record, and display various physical quantities, chemical compositions, or process parameters. They are widely used in industrial production, environmental monitoring, healthcare, and scientific research to ensure operational safety, efficiency, and product quality. Monitoring instruments help users understand the system's operating status in real time and make adjustments or take corrective measures as needed. In chemical production processes, heat exchange equipment may leak due to age or other reasons, allowing flammable or toxic gases from the process gas to enter the circulating water system and cause major safety accidents. Therefore, monitoring circulating water leaks in critical process heat exchange equipment is crucial, and real-time monitoring using online analyzers is of great significance for stable and safe production.

[0003] Based on the above, the inventors have discovered the following problems: the current method of monitoring leaked gas from circulating water has high pressure and temperature, and contains a large amount of water and impurities, which greatly affects the measurement data. In addition, the high temperature and high pressure will reduce the service life of the analytical instruments, making them inconvenient to use.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a gas leak monitoring device, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a gas leak monitoring device to solve the problems mentioned in the background art.

[0006] A gas leak monitoring device includes a liquid inlet assembly, a monitoring assembly on one side of the liquid inlet assembly, the monitoring assembly including a cooler, a liquid inlet port at the top of one end of the cooler connected to the liquid inlet assembly, a vent port at the top of the other end of the cooler, and a water inlet port at the bottom of the cooler, the vent port connected to a gas-liquid separator, a protective filter connected to one side of the gas-liquid separator, a butterfly filter connected to the bottom of the protective filter, a rotor flow meter connected to the bottom of the butterfly filter, an online gas analyzer connected to the bottom of the rotor flow meter, and an exhaust port on one side of the online gas analyzer.

[0007] By adopting the above technical solution, the liquid inlet component facilitates the control of a certain amount of circulating water entering the monitoring component for detection. The cooler facilitates the cooling of the circulating water entering the monitoring component, and the lower temperature leads to a decrease in gas solubility, thereby releasing some dissolved gas and generating gas-liquid separation, which facilitates subsequent component detection. The gas-liquid separator is connected through the vent interface, which facilitates further gas-liquid separation of the gas discharged from the cooler. The protective filter facilitates the preliminary filtration of the separated gas to remove larger particles, moisture, and other contaminants. The butterfly filter facilitates the further removal of fine particles, moisture, and any remaining oil mist and other minute impurities after the preliminary filtration, ensuring that the gas entering the online gas analyzer reaches a very high purity standard. The rotor flow meter facilitates the measurement of the purified gas flow rate, and the online gas analyzer facilitates the component analysis of the purified gas, thus achieving the function of online monitoring.

[0008] Furthermore, the gas-liquid separator is provided with a drain valve at the bottom, and the drain valve is provided with a drain port at the bottom.

[0012] Furthermore, a three-way pipe connects the gas-liquid separator and the protective filter, and a purge gas interface is provided at the top of the three-way pipe.

[0013] By adopting the above technical solution, a purging gas interface is provided at the top of the three-way pipe, which facilitates the connection of the purging gas interface to the external gas pipeline, making it convenient to access high-pressure gas flow to purge the inside of the device and avoid residues affecting the next component analysis.

[0014] Furthermore, the liquid inlet assembly includes a multi-channel reversing valve, which has several input interfaces on one side. Each input interface is connected to a pressure reducing valve, and the pressure reducing valve has a communication interface on one side.

[0015] By adopting the above technical solution, a connection interface is provided on one side of the pressure reducing valve, which facilitates connection with external pipelines. This allows for easy connection between the circulating water systems of multiple heat exchange devices and the device. The pressure reducing valve controls the corresponding circulating water system to release a certain amount of circulating water into the device, which facilitates monitoring of the circulating water leakage of the circulating water system and reduces pressure to avoid excessive pressure affecting the device and thus improve its service life.

[0016] Furthermore, the output end of the multi-channel reversing valve is connected to a heat exchanger, and both ends of the top of the heat exchanger are provided with heat exchange interfaces.

[0017] By adopting the above technical solution, the heat exchanger is designed to facilitate the connection of the heat exchange interface to the external transmission pipeline, allowing the heat exchange medium to be introduced into the heat exchanger to absorb the heat of the circulating water sample and reducing energy loss.

[0018] Furthermore, one end of the heat exchanger is connected to a temperature measuring tube, and a temperature sensor is provided in the middle of the temperature measuring tube.

[0019] By adopting the above technical solution, a temperature sensor is installed in the middle of the temperature measuring tube, which facilitates the temperature measurement of the circulating water sample after heat exchange as it flows through the temperature measuring tube. This makes it easier to control the output power of the cooler and reduce energy waste.

[0020] Furthermore, a sampling pump is provided at one end of the temperature measuring tube, the input end of the sampling pump is connected to the temperature measuring tube, and the output end of the sampling pump is connected to the liquid inlet.

[0021] By adopting the above technical solution and setting up a sampling pump, it is convenient to pump circulating water samples into the monitoring component for leak gas detection.

[0022] Furthermore, the multi-channel reversing valve has a purge port at one end, the purge port is connected to a shut-off valve, and the shut-off valve has a discharge port on one side.

[0023] By adopting the above technical solution, a shut-off valve is connected through the purge port, and a discharge port is provided on one side of the shut-off valve, which facilitates the connection between the discharge port and the external pipeline, so that the purge gas can carry the residual gas and liquid out from the discharge port.

In the gas-liquid separation step, a protective filter 10206 is connected to one side of the gas-liquid separator 10202. The protective filter 10206 facilitates preliminary filtration of the separated gas to remove larger particles, moisture, and other contaminants.

This connection port 10109 facilitates connection to external pipelines, allowing the circulating water systems of multiple heat exchange devices to connect to the device. The pressure reducing valve 10108 controls the corresponding circulating water system to release a certain amount of circulating water into the device, facilitating monitoring of circulating water leakage in the circulating water system and reducing pressure to prevent excessive pressure from affecting the device and thus extending its service life.

[0037] The multi-channel reversing valve 10101 is connected to a heat exchanger 10102 at its output end.

This allows for easy connection between the circulating water systems of multiple heat exchange devices and the device. The pressure reducing valve 10108 controls the corresponding circulating water system to release a certain amount of circulating water into the device, facilitating monitoring of leaks in that circulating water system and reducing pressure to prevent excessive pressure from affecting the device and extending its service life. The heat exchanger 10102 facilitates connection of the heat exchange interface 10106 to external transmission pipelines, allowing the heat exchange medium to enter the heat exchanger 10102 to absorb heat from the circulating water sample, reducing energy loss.

This allows for control of the output power of the cooler 10201, reducing energy waste. The sampling pump 10105 facilitates pumping the circulating water sample into the monitoring component 102 for leak gas detection. The cooler 10201 cools the circulating water entering the monitoring component 102, lowering the temperature and reducing gas solubility, thus releasing some dissolved gas and causing gas-liquid separation. This facilitates subsequent component analysis. A gas-liquid separator 10202 is connected via a vent 10212 for further processing of the gas discharged from the cooler 10201. Gas-liquid separation is achieved through the inclusion of a protective filter 10206, which facilitates preliminary filtration of the separated gas to remove larger particles, moisture, and other contaminants.
