Description

Technical Field

[0002] With the rapid development of industries such as industry, environmental protection and chemical industry, the importance of on-site analysis technology in various practical application scenarios has become increasingly prominent. This technology plays a key role in process production material analysis, emergency accident handling, environmental monitoring and emergency response. Through on-site analysis, data can be quickly obtained and decision-making can be fed back in time, providing an effective basis for subsequent processing.

[0003] However, most existing analytical equipment and sampling devices are designed for laboratories, and generally have problems such as large size, heavy weight, inconvenient to carry, and complex operation. They usually rely on external power supplies and fixed instrument environments. These limitations make it difficult to perform efficient and accurate analysis under field conditions. In addition, traditional equipment often encounters the following difficulties during field collection and processing:

[0004] 1. The process samples contain high levels of water and oil, which can easily damage the components of the analytical instrument. In addition, the process requires the detection of cryogenic samples such as liquid nitrogen and liquid helium, and the extremely low temperatures of these samples can also easily damage the instrument.

[0005] 2. The existing equipment has relatively simple or missing control functions for parameters such as temperature, pressure and injection speed, which in turn affects the accuracy and precision of the data.

[0006] 3. The process production environment is harsh, and the existing equipment has insufficient anti-interference capabilities and cannot effectively respond to analysis needs under complex conditions.

[0007] 4. On-site analysis needs to meet the requirements of different test items. The current single-function sampling device lacks sufficient flexibility and cannot be dynamically adjusted according to the different characteristics of the sample, which limits the scope of application of the equipment.

In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may also be implemented by those skilled in the art without these specific details.

[0052] like Figure 1 and Figure 2As shown, an embodiment of the present invention discloses a portable multifunctional gas-liquid sampling device for process field analysis, including a housing 1, a collection system 2, a heating module 3, a filtering module 4, a control module 5, a hidden base 6 and a plurality of pipelines.

[0053] A handle 8 is provided on the upper portion of the housing 1 , and the handle 8 is connected to the housing 1 .

[0054] The housing 1 is provided with a handle 8 to improve the portability of the device, wherein the housing 1 and the handle 8 are both made of polycarbonate.

[0055] The collection system 2 , the heating module 3 , the filtering module 4 and the control module 5 are all connected to the housing 1 , and the collection system 2 is in communication with the heating module 3 and the filtering module 4 .

[0056] The control module 5 is electrically connected to the collection system 2 , the heating module 3 and the filtering module 4 .

[0057] The hidden base 6 is located at one side of the housing 1 , and the hidden base 6 is slidably matched with the housing 1 .

[0058] like Figure 3 and Figure 4 As shown, the collection system 2 includes an access component 201, an inlet temperature sensor 202, an inlet pressure regulating valve 203, an inlet pressure gauge 204, an inlet micro ultrasonic flow meter 205, a small vacuum pump 206, a first electric three-way valve 207, a second electric three-way valve 208, an outlet pressure gauge 209, an outlet micro ultrasonic flow meter 2010, an outlet temperature sensor 2011, a third electric three-way valve 2012, an exhaust component 2013 and an exhaust port 2014.

[0059] The discharge component 2013, the inlet temperature sensor 202, the inlet pressure regulating valve 203, the inlet pressure gauge 204, the inlet micro ultrasonic flow meter 205, the small vacuum pump 206, the first electric three-way valve 207, the second electric three-way valve 208, the outlet pressure gauge 209, the outlet micro ultrasonic flow meter 2010, the outlet temperature sensor 2011, the third electric three-way valve 2012 and the discharge component 2013 are connected in sequence through pipelines.

[0060] The exhaust port 2014 is connected to the third electric three-way valve 2012 .

[0061] The access component 201 adopts a two-way valve design, which can be connected to the material outlets of devices with different calibers and sizes to meet the testing requirements of production devices of different specifications. When idle, the access component 201 is equipped with a plug, which can close the gas path of the device to avoid gas path contamination and ensure the cleanliness of the pipeline when it is used next time.

[0062] After the gas enters the collection system 2 through the access component 201, the temperature is first monitored by the inlet temperature sensor 202 to detect the temperature parameters of the gas in real time and provide accurate temperature data for subsequent analysis. At the same time, the inlet pressure regulating valve 203 controls the pressure of the gas injection, and adjusts the pressure in cooperation with the small vacuum pump 206 to ensure that the low-boiling point liquid sample can be quickly vaporized to meet the sampling requirements. Among them, the inlet pressure gauge 204 and the micro ultrasonic flow meter provide pressure and flow rate values ​​respectively to help the operator adjust the valve to ensure that the gas is sampled under the best conditions.

[0063] The small vacuum pump 206 is used to create and maintain a low-pressure environment, facilitate the smooth entry and processing of materials, and provide appropriate pressure for the gasification of low-boiling-point liquid samples. The first electric three-way switching valve and the second electric three-way switching valve are connected to the control module 5, and the conventional gas sampling mode and the heating sampling mode are switched through the control panel to meet different test requirements.

[0064] Before the airflow leaves the collection system 2, the outlet pressure gauge 209 and the outlet micro ultrasonic flow meter 2010 monitor the pressure and flow rate at the outlet respectively, further ensuring that the sample is collected under the most appropriate conditions. The outlet temperature sensor 2011 is used to monitor the temperature of the outlet gas in real time to ensure that the sample temperature is within the set range to avoid affecting the analysis results due to improper temperature. The discharge component 2013 adopts a two-way valve design, which is connected to material outlets of different calibers and is also equipped with a plug, which can effectively avoid contamination of the gas path when it is idle and ensure the purity of the sample when it is used next time.

[0065] In addition, the exhaust port 2014 is connected to the exhaust component 2013 for safely exhausting the exhaust gas in the gas. The third electric three-way valve 2012 plays a key role in the system. When the gas sample does not meet the set temperature, pressure and other parameters, it will automatically switch the gas path and switch the outlet to the exhaust gas outlet to safely discharge the gas that does not meet the sampling conditions, thereby ensuring the stability and safety of the sampling system.

[0066] Through the collaboration of the above components, the acquisition system 2 can flexibly adjust key parameters such as the temperature, pressure, and flow rate of the airflow to ensure the efficiency and accuracy of process site analysis.

[0067] The heating module 3 includes a temperature control box 301 , a heat preservation layer 302 , a heating plate 303 and a heat insulation plate 304 .

[0068] The temperature control box 301 is located at the lower part of the inner side of the shell 1 , and the temperature control box 301 is connected to the shell 1 .

[0069] A heating plate 303 is disposed inside the temperature control box 301 , and the heating plate 303 is connected to the temperature control box 301 .

[0070] The inner wall of the temperature control box 301 is provided with a heat preservation layer 302 , and the outer wall of the temperature control box 301 is provided with a heat insulation layer. Both the heat preservation layer 302 and the heat insulation layer are connected to the temperature control box 301 .

[0071] The temperature control box 301 is the core component of the heating module 3. It monitors the temperature change of the sample in real time by cooperating with the outlet temperature sensor 2011, and automatically adjusts the heating power of the heating plate 303 according to the monitoring results to ensure that the sample is sampled within the set temperature range. The heating plate 303 is located at the bottom of the temperature control box 301 and provides a stable heating function to meet the needs of sample heating.

[0072] In order to ensure the temperature stability during the heating process, the inner wall of the temperature control box 301 is provided with an insulation layer 302. The insulation layer 302 adopts aerogel insulation coating material, which can effectively reduce heat loss and ensure that the temperature remains constant. At the same time, it greatly prolongs the battery life of the device and improves the use efficiency and durability of the device.

[0073] The outer wall of the temperature control box 301 uses polyurethane coating as a heat insulation layer, which can effectively isolate the high temperature generated by the heating module 3 and avoid interference or damage to other functional modules of the installation.

[0074] Through the coordinated work of the temperature control box 301, the heating plate 303, the insulation layer 302 and the thermal insulation layer, the entire heating module 3 can accurately control the temperature change, ensure that a stable and reliable temperature environment can be provided during the process site analysis, ensure the stability and safety of the overall system, and realize the analysis and detection of deep-cold samples such as liquid nitrogen and liquid helium in the process, meet the sample constant temperature requirements, and thus ensure the accuracy of sample sampling and analysis.

[0075] Among them, a horizontal spiral pipe is set between the first electric three-way valve 207 and the second electric three-way valve 208, the horizontal spiral pipe is connected to the first electric three-way valve 207 and the second electric three-way valve 208, and the horizontal spiral pipe is located inside the temperature control box 301.

[0076] The horizontal spiral pipe prolongs the residence time of the gas in the pipe by increasing the path of gas flow, which enables the sample to fully contact the heat of the heating plate 303 when passing through the pipe, thereby achieving more uniform heating and temperature regulation and ensuring the temperature stability of the airflow.

[0079] The fourth electric three-way valve 405, the fifth electric three-way valve 406, the sixth electric three-way valve 407 and the seventh electric three-way valve 408 are connected to the dust removal trap 401, the water removal trap 402, the oil removal trap 403 and the ion exchange trap 404 through pipelines respectively, and the dust removal trap 401, the water removal trap 402, the oil removal trap 403 and the ion exchange trap 404 are all connected through pipelines.

[0081] The dust trap 401 is made of absorbent cotton, which can effectively capture coarse dust particles in the gas path, thereby preventing solid impurities from affecting the quality of the sample. The moisture trap uses color-changing silica gel filler, which can efficiently absorb moisture in the gas, protect the analytical equipment from moisture damage, and ensure long-term stable operation of the equipment. The oil removal trap 403 uses polyethylene filler, which has good oil adsorption capacity and can effectively prevent oil mist or oil gas from interfering with the instrument and analysis results. The ion exchange trap 404 is specifically used to remove ionic pollutants in the sample, such as ammonia or acidic gas (such as sulfur dioxide), to ensure the accuracy of the sample composition and not be affected by ionic contamination.

[0082] In order to achieve flexible switching of filtering modes, the filtering module 4 is configured with multiple electric three-way valves, including a fourth electric three-way valve 405, a fifth electric three-way valve 406, a sixth electric three-way valve 407, a seventh electric three-way valve 408, an eighth electric three-way valve 409 and a ninth electric three-way valve 4010, which are connected to the control module 5. The operator can easily select different filtering modes through the control module 5, automatically adjust the filtering route according to the gas purity requirements, avoid the loss of components, and thus improve the accuracy and precision of the experiment.

[0083] The portable multifunctional gas-liquid sampling device for process field analysis further comprises a visual window 7 , which corresponds to the filter module 4 and is connected to the housing 1 .

[0084] The operator can clearly see the working condition of the filtration module 4 through the visual window 7, so as to observe the state and internal condition of the capture trap in real time and promptly discover possible blockage or saturation, which is helpful for maintenance and management and ensures the accuracy and reliability of sample analysis.

[0099] The implementation principle of the portable multifunctional gas-liquid sampling device for process field analysis of the present invention is as follows:

[0100] The device is connected to the sample to be analyzed through the access component 201, and a small vacuum pump 206 is used to create a low-pressure environment, so that the sample can enter the sampling system smoothly. The inlet pressure regulating valve 203 adjusts the injection pressure to ensure that the low-boiling point liquid sample can be quickly vaporized and enter the sampling system. The inlet pressure gauge 204 and the inlet micro ultrasonic flow meter 205 monitor the injection pressure and flow rate in real time, optimize the sampling conditions, and ensure that the sample is collected in the best state.

[0101] When heating is required, the heating module 3 of the device heats the sample to ensure that the sample is sampled within the set temperature range. The temperature sensor in the temperature control box 301 monitors the sample temperature in real time and automatically adjusts the heating power of the heating plate 303 according to the monitoring results to keep the sample temperature stable and meet different test requirements.

[0102] The collected samples are processed by a multi-stage filtration system, and sequentially pass through a dust removal trap 401, a water removal trap 402, an oil removal trap 403, and an ion exchange trap 404, effectively removing solid particles, moisture, oil mist, and ion pollutants in the gas to ensure sample purity. The operator can adjust different filtration modes through the control module 5 and optimize the filtration settings to improve the experimental accuracy and sample quality.

[0103] The core processing platform 502 in the device is responsible for collecting data collected by various sensors (such as flow meters, temperature sensors, pressure sensors, etc.), and processes them through built-in algorithms to ensure that the device operates stably within the set parameter range. All collected parameters and equipment status information are displayed in real time through the touch digital display screen 501, and the operator can intuitively monitor the working status of the device, adjust parameters and switch modules.

[0104] Finally, the processed gas is discharged through the exhaust component 2013 or the exhaust port 2014 to ensure the smooth operation of the system. When the sample does not meet the set conditions, the third electric three-way valve 2012 automatically switches to the exhaust mode to guide the unqualified gas to the exhaust port 2014 for discharge, thereby ensuring the safety and effectiveness of the sampling process. Through the coordinated work of the above modules, the device can flexibly adjust the sampling conditions to ensure the efficiency, accuracy and reliability of the process site analysis.

The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
