The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples.
The embodiment of the utility model provides an inserted gas sensor probe assembly, as shown in fig. 1, this inserted gas sensor probe assembly includes probe unit 1, probe unit 1 includes sampling tube 101, the one end of sampling tube 101 is for inserting end 102, be provided with prefilter 103, vacuum filter 104 and explosion-proof solenoid valve 105 on the sampling tube 101 along the gaseous flow direction of sample; the probe units 1 are arranged in a plurality of numbers, wherein two probe units 1 are respectively connected with one end of a first quick-connection tee joint 2 to form a probe module 3.
In one embodiment, the insertion end 102 is inserted into a device or environment to be tested for a gas, including but not limited to a pipe and a reactor, to detect the concentration of the gas at the corresponding insertion point. The probe module 3 has two probe units 1 and thus two insertion ends 102, which can correspond to the points where the gas to be detected is inserted. Taking gas detection of a bottom-heated high-temperature reactor as an example, temperatures at different heights in the high-temperature reactor are different, so that detection of corresponding gases including, but not limited to, oxygen, carbon dioxide, hydrogen, and the like is necessary for point locations at different heights. Also, for example, when the gas detecting device is applied to detection of a certain gas in a mixed gas, since parameters such as the molar mass and the weight of the detected gas are different from those of other mixed gas, it is necessary to detect the gas concentration at different points (for example, at different heights). In the application scenario, the present embodiment can utilize the advantage of multiple points, utilize the opening and closing of the explosion-proof electromagnetic valve 105 to realize the time-staggered sampling of the gas at different points, and realize the detection of the components or the concentration of the gas through one detection component 7. The core component of the gas sensor is the detection component, and the probe assembly is optimally designed in the embodiment, so that one detection component 7 can complete multi-point detection, and the detection cost is reduced.
It should be noted that the detection component 7 shown in fig. 1 is a first quick-connection tee 2 directly connected to the gas inlet end thereof through a pipeline, and is suitable for gas detection on the pipeline and gas detection in a reaction container or a storage container with relatively large gas pressure in the device body, and in other application scenarios where sampling pressure needs to be provided, a pump product can be added between the first quick-connection tee 2 and the detection component 7 to provide gas inlet pressure. It is understood that the detecting component 7 is an existing component capable of detecting gas components or concentrations, and may be, for example, a semiconductor gas sensor, an electrochemical gas sensor, a catalytic combustion gas sensor, a thermal conductivity gas sensor, an infrared gas sensor, a solid electrolyte gas sensor, or the like, and the embodiment is not limited to the detecting component 7, and may be applied to any gas sensor requiring gas sampling.
The vacuum filter 104 is used to filter contaminants (typically dust) in the sampled gas to avoid the contaminants in the sampled gas from interfering with the detection and to reduce wear on the detection components.
The pre-filter 103 is used for performing preliminary filtering on the sampled gas, as shown in fig. 2, the pre-filter 103 includes a water mist filter 1031 and an oil-water filter 1032, and is used for filtering water mist and oil-water in the sampled gas to ensure detection accuracy.
In some embodiments, as shown in fig. 2, the sampling tube 101 is provided with a sample gas sampling valve 1033 between the water mist filter 1031 and the oil water filter 1032. Sample gas sampling valve 1033 is used to adjust the flow rate of the sample gas.

The probe modules 3 can also be connected with the detection part through a third quick-connection tee joint 8 so as to send the sampling gas to the detection part for detection.
In some embodiments, as shown in fig. 4, a flow sensor 5 is disposed on the sampling tube 101 to monitor the gas flow of the single sampling gas.
More specifically, as shown in fig. 4 and 5, the plug-in gas sensor probe assembly further comprises a controller 6, wherein a signal output end of the flow sensor 2 is connected with a signal input end of the controller 6, and a signal output end of the controller 6 is connected with the explosion-proof solenoid valve 105.
It should be noted that, when bayonet gas sensor probe subassembly be applied to in the middle of the gas detection appearance, can select the detection chip that gas detection appearance was equipped with as controller 6. The specific working principle of the controller 6 is as follows: according to the preset single sampling gas quantity of one sampling port, based on the flow signal detected by the current sampling tube 101 and detected by the flow sensor 5, when the required sampling gas quantity is reached, the explosion-proof electromagnetic valve 105 of the sampling tube 101 is controlled to be closed, the automatic gas sampling of a plurality of sampling tubes is repeated, and the like, so that the gas sampling detection of a plurality of sampling point positions is realized.
The above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
