Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of detection equipment, and particularly relates to a methanol detector performance testing device. BACKGROUND
[0002] At present, methanol fuel power ships are gradually popularized and applied, and methanol fuel engines use methanol as fuel. Methanol is a flammable and explosive gas after volatilization. In order to ensure the safe navigation of the ship, the concentration of methanol gas in the air, pipeline and other areas needs to be strictly monitored, and the methanol detector is a core component for detecting the concentration of methanol.
[0003] Because the working conditions of marine equipment are very complex, for example, there are high temperature difference and high salt mist and water vapor use scenarios. These external interference factors will affect the use performance of the methanol detector, so the methanol detector needs to have the accuracy of detection under complex and harsh working conditions.
[0004] Therefore, the performance of the methanol detector needs to be accurately tested.
[0005] CONTENT
[0006] The present application provides a methanol detector performance testing device, so as to accurately test the performance of the methanol detector and ensure the regular use of the methanol detector.
[0007] A methanol detector performance testing device comprises a box body having a closed test cavity; a storage reservoir in communication with the test cavity for introducing methanol into the test cavity; a sprayer in communication with the test cavity for providing spray to the test cavity; a filter in communication with the test cavity for filtering the mist, and a gas analyzer in communication with the end of the filter away from the test cavity.
[0008] To realize the above technical solution, the test process is as follows: before testing, the methanol detector is placed in the test cavity, the operator controls the storage reservoir to introduce a certain amount of methanol into the test cavity, and controls the sprayer to spray a certain amount of mist into the test cavity. The gas filled in the test cavity is a mixed gas of methanol, air and mist, thereby simulating the use scenario of the methanol detector in high mist and high humidity. The mixed gas flows out of the test cavity, the mist part is filtered out by the filter, and finally the methanol content is detected by the gas analyzer, that is, the methanol content in the test cavity at this time. The measurement result of the methanol detector is compared with the measurement result of the gas analyzer, so as to determine whether the methanol detector can ensure the accuracy of the test under the influence of the mist. Generally, the gas analyzer may not be accurate when detecting high mist gas. In the present application, the combination of the filter and the gas analyzer can ensure that the result obtained by the gas analyzer is accurate, thereby ensuring the accuracy of the overall detection result.
[0009] As one of the optional embodiments of the present scheme, the quantitative input device is further connected with the storage device at one end and with the test chamber at the other end, and the methanol in the storage device is input into the test chamber through the quantitative input device.
[0010] As one of the optional embodiments of the present scheme, the quantitative input device comprises a first controller, and the gas analyzer is electrically connected with the first controller, so as to transmit the methanol parameter detected by the gas analyzer to the first controller in real time.
[0011] The quantitative input device can accurately input the methanol into the test chamber, so that the mixed gas in the test chamber can more accurately and multi-levelly simulate the real use scene of the methanol, and the performance of the methanol detector can be tested comprehensively and accurately; and the first controller can supplement or stop the input of the methanol into the test chamber according to the feedback of the gas analyzer, that is, the quantitative input device can dynamically maintain the methanol content in the test chamber under the feedback of the first controller, and more flexible methanol supply can be provided in the long-period endurance detection or dynamic detection of the methanol detector.
[0012] As one of the optional embodiments of the present scheme, the heater is further arranged to heat the test chamber to a preset temperature.
[0013] As one of the optional embodiments of the present scheme, the heater comprises a base and a heating wire arranged in the base, and the box body is arranged on the base.
[0014] As one of the optional embodiments of the present scheme, the heater further comprises a temperature sensor arranged in the box body to detect the temperature in the test chamber.
[0015] As one of the optional embodiments of the present scheme, the heater further comprises a second controller, and the temperature sensor is electrically connected with the second controller to transmit the temperature signal to the second controller.
[0016] The heater can heat the temperature in the test chamber to a preset temperature, so as to simulate the use scene of the methanol detector in a high-temperature environment, which further enriches the real degree of the simulated environment and more diversifies the real scene of the methanol detector, so as to more accurately test the performance and function of the methanol detector. The cooperation of the temperature sensor and the second controller can dynamically maintain the temperature in the test chamber, so that the temperature can be more flexibly regulated in the long-period endurance detection or dynamic detection of the methanol detector to meet the requirements.
[0017] As one of the optional embodiments of the present scheme, the liquid supply mechanism is further included, which comprises a water storage container and an oil storage container, both of which are communicated with the sprayer to supply water or oil.
[0018] The above technical scheme is realized, and the liquid supply mechanism can more accurately simulate the use scenario of the methanol detector in high mist and high oil mist, so that the simulation environment is enriched and the methanol detector is more accurately detected.
[0019] As one of the optional embodiments of the present scheme, the stirring fan is further included, which is arranged in the box and is used to stir the gas in the test cavity uniformly.
[0020] As one of the optional embodiments of the present scheme, the test port is arranged on the box and is communicated with the outside, the filter is communicated with the test port, and the bracket is arranged on one side of the box and is used to install the methanol detector.
[0021] The above technical scheme is realized, and the methanol detector and the gas analyzer are arranged at a relatively far position, which leads to a large difference in the detection of the gas source, which will interfere with the detection result. However, in the present application, the gas received by the methanol detector and the gas analyzer is from the gas flowing out of the test port, which makes the gas detected by the two more close, reduces the interference, and improves the accuracy of the detection result.
[0022] One of the above technical schemes has the following advantages or beneficial effects:
[0023] Before testing, the methanol detector is placed in the test cavity, the operator controls the reservoir to introduce a certain amount of methanol into the test cavity, and controls the sprayer to spray a certain amount of mist into the test cavity. The gas filled in the test cavity is a mixed gas of methanol, air and mist, thereby simulating the use scenario of the methanol detector in high mist and high humidity. The mixed gas flows out of the test cavity, and the mist part is filtered out by the filter. Finally, the methanol content is detected by the gas analyzer, that is, the methanol content in the test cavity at this time. Then, the measurement result of the methanol detector is compared with the measurement result of the gas analyzer, so as to determine whether the methanol detector can ensure the accuracy of the test under the influence of the mist. Generally, the gas analyzer may not be accurate when detecting high mist gas. However, in the present application, the combination of the filter and the gas analyzer can ensure that the result obtained by the gas analyzer is accurate, thereby ensuring the accuracy of the overall detection result.

[0031] The following will be described in detail with reference to the drawings in the embodiments of the present application. Figures 1-3 Further description will be made to the present application.

[0033] The box 1 is made of corrosion-resistant steel plate or aluminum plate, etc. The box 1 is designed with an exhaust structure. In an example, the exhaust structure can be an exhaust pipe 13, which is in communication with the test cavity 10. The exhaust pipe 13 is provided with an exhaust valve 131 at the end away from the box 1. The reservoir 2 refers to a container for storing methanol. In an example, the reservoir 2 can be a methanol bottle or a methanol tank. The methanol bottle is provided with a valve. By screwing the valve of the methanol bottle, the gas supply or stop can be realized.
[0034] The sprayer 3 refers to a device capable of spraying atomized liquid into the box 1. In an example, the sprayer 3 can include an atomizing nozzle and a compressor, which provides high-pressure liquid to the atomizing nozzle. After passing through the atomizing nozzle, the liquid is sprayed into the test cavity 10 in the form of mist.
[0035] The filter 4 is a device for filtering mist. In an example, the filter 4 can be a vapor-liquid separation filter 4, which is mature in the prior art and will not be described here. The gas analyzer 5 refers to a process analyzer for measuring gas composition. Commonly used are thermal conductivity gas analyzers 5, electrochemical gas analyzers 5, and infrared absorption analyzers, etc.
[0036] In the embodiment of the present application, the test process is as follows: before testing, the methanol detector is placed in the test cavity 10. The operator controls the reservoir 2 to supply a certain amount of methanol into the test cavity 10, and controls the sprayer 3 to spray a certain amount of mist into the test cavity 10. The gas filled in the test cavity 10 is a mixture of methanol, air and mist, thereby simulating the use scenario of the methanol detector in a high-mist and high-humidity environment. The mixed gas flows out of the test cavity 10, and the mist part is filtered out by the filter 4. Finally, the methanol content is detected by the gas analyzer 5, that is, the methanol content in the test cavity 10 at this time. The measurement result of the methanol detector is compared with the measurement result of the gas analyzer 5, so as to determine whether the methanol detector can ensure the accuracy of the test under the influence of mist. Generally, the gas analyzer 5 may not be accurate when detecting high-mist gas. In the present application, the combination of the filter 4 and the gas analyzer 5 can ensure that the result obtained by the gas analyzer 5 is accurate, thereby ensuring the accuracy of the overall test result.

[0038] The quantitative input device 6 is configured to quantitatively control the amount of methanol gas input into the test cavity 10. In an example, the quantitative input device 6 includes a flow meter, a regulating valve, a display, and the like.
[0039] As an optional embodiment of the present application, the quantitative input device 6 includes a first controller 61, and the gas analyzer 5 is electrically connected to the first controller 61, so as to transmit the methanol parameter detected by the gas analyzer 5 to the first controller 61 in real time.
[0040] In the embodiment of the present application, the quantitative input device 6 can quantitatively and accurately inject methanol into the test cavity 10, so that the mixed gas in the test cavity 10 can more accurately and multi-levelly simulate the real use scene of methanol, thereby facilitating comprehensive and accurate testing of the performance of the methanol detector. In addition, the first controller 61 can supplement or stop the input of methanol into the test cavity 10 in real time according to the feedback of the gas analyzer 5, that is, under the feedback of the first controller 61, the quantitative input device 6 can dynamically maintain the methanol content in the test cavity 10, thereby providing more flexible methanol supply during long-period durability detection or dynamic detection of the methanol detector.
[0041] It should be noted that the control of the first controller 61 on the quantitative input device 6 can be realized by controlling the valve in the quantitative input device 6. Since the valve in the quantitative input device 6 is generally an electromagnetic valve, the first controller 61 can send a control signal to the electromagnetic valve to achieve more accurate and rapid control.

[0045] As an optional embodiment of the present application, the heater 7 further includes a second controller 73, and the temperature sensor 8 is electrically connected to the second controller 73, so as to transmit the temperature signal to the second controller 73.
[0046] In the embodiment of the present application, the heater 7 can heat the temperature in the test cavity 10 to a preset temperature, thereby simulating the use scenario of the methanol detector in a high-temperature environment, which further enriches the authenticity of the simulated environment and more diversifies the real scenario of the methanol detector, so as to more accurately test the performance and function of the methanol detector. The cooperation of the temperature sensor 8 and the second controller 73 can dynamically maintain the temperature in the test cavity 10, which makes it more flexible to regulate the temperature during long-period durability testing or dynamic testing of the methanol detector to meet the needs.
[0047] It should be noted that the control of the second controller 73 on the heater 7 can be realized by controlling the size of the current by the second controller 73. The electric heater 7 has an automatic temperature control function, which will not be described here.

[0049] Specifically, the water storage container 91 and the oil storage container 92 can be in communication with the sprayer 3 respectively, or can be combined through a pipeline and then be in communication with the sprayer 3. The communication referred to here means that the water storage container 91 or the liquid storage container is in communication with the compressor in the sprayer 3, which enables the compressor to deliver water or oil in the liquid supply mechanism 9 to the atomizing nozzle.

[0054] In the embodiment of the present application, the methanol detector and the gas analyzer 5 are arranged at a relatively far position, which leads to a relatively large difference in detecting the gas source, and this can interfere with the detection result. In the present application, the gas received by the methanol detector and the gas analyzer 5 is all from the gas flowing out of the test port 100, which makes the gas detected by the two more close, reduces the interference, and improves the accuracy of the detection result.
