The first electromagnet 211 and the second electromagnet 221 are simultaneously attracted to the magnetic rings 15 on the two elastic connection pipes 14, and certainly are simultaneously separated from contact with the magnetic rings 15 on the two elastic connection pipes 14.
Referring to fig. 2 and 5, a refrigerating module 31 is disposed in the housing 11, and the refrigerating module 31 is used for cooling the pre-treated sample chamber 13 filled with the gas to be tested, so that moisture in the gas to be tested in the pre-treated sample chamber 13 is condensed on the pipe wall of the pre-treated sample chamber 13.

When the circulation pump 41 is started, the gas in the two pretreatment sample tanks 13 starts to circulate. In some possible implementations, the circulation pump 41 uses a peristaltic pump.
After the mixing process is completed, the moisture analysis system (laser dew point) begins to detect the gas in the second pre-treatment sample compartment. Of course, in order to ensure the accuracy of the detection process, the weight of the first pretreated sample compartment needs to be monitored synchronously during the gas mixing process until the weight value of the first pretreated sample compartment is stable.
For the pretreatment sample bin 13, an automatic closing capability needs to be provided, that is, a valve is arranged on the pretreatment sample bin 13, and the valve can be opened and closed in a bidirectional manner by air pressure, and the specific structure of the valve is as follows:
The valve is arranged at the joint of the pretreatment sample bin 13 and the elastic connecting pipe 14, the valve uses a sliding valve core to realize bidirectional opening and closing, two air holes are formed in the valve core, and when any one end of the valve core slides out of a channel (the air pressure difference at two sides of the valve core changes), a channel is formed to communicate the space inside and outside the pretreatment sample bin 13. A spring is respectively arranged at two ends of the valve core and used for limiting the valve core in the channel.
The purging module 5 is arranged in the shell 11 and is used for drying the pretreated sample cabin, and the purpose of drying is to enable the pretreated sample cabin 13 to complete regeneration, so that the pretreated sample cabin 13 can be recycled in the shell 11.
Referring to fig. 8, in some examples, the purge module 5 includes an air source 51, a purge air pipe 52, and a third electromagnet 53, where a first end of the purge air pipe 52 is connected to the air source 51, a second end of the purge air pipe 52 extends into the housing 11, and the second end of the purge air pipe 52 is further provided with the third electromagnet 53, and the third electromagnet 53 is used to automatically connect the purge air pipe 52 with the pretreatment sample bin 13.

In some possible implementations, the purge gas pipe 52 is further provided with a heating wire for heating the gas output from the gas source 51.
The transfer pump 21, the refrigerating module 31, the converting module 4 and the purge module 5 are sequentially disposed around the rotation direction of the electric swing bracket 12 to complete the detection process and the regeneration process of the pretreatment sample cartridge 13 described in the above.
In the whole, the moisture analysis pretreatment system of the high-sulfur natural gas dehydration device provided by the application uses a cooling dehydration treatment mode to dehydrate a gas tested (high-sulfur high-humidity natural gas), and then realizes accurate measurement of moisture in the gas tested (high-sulfur high-humidity natural gas) in a gas partial transfer mode, wherein the mode can accurately measure the moisture content in the gas tested (high-sulfur high-humidity natural gas).

In some examples, a test section 131 is present on the middle portion of the pre-treatment sample cartridge 13, the diameter of the test section 131 tending to decrease first and then to increase. The function of the test section 131 is to enable the gas to be tested to be mixed more fully, so that the detection direction of the laser dew point meter is more accurate.
It should be appreciated that the gas in the pre-treatment sample chamber 13 is tested in a flowing state during the detection process, and the use of the test section 131 can increase the local gas flow velocity in the pre-treatment sample chamber 13, which can result in better gas mixing. It is also possible to keep the gas mixing zone away from the moisture that condenses or solidifies onto the walls of the pretreatment sample compartment 13.
In some possible implementations, the smallest diameter of the test section 131 is 10% -20% of the diameter of the pre-treatment sample cartridge 13.

In the rotation direction of the electric rotating bracket 12, the heating module 6 is positioned behind the purging module 5.
The heating module 6 is composed of a lift type heating stage 61 installed in the housing 11 and a heating device 62 installed on the lift type heating stage 61, and the heating device 62 may use, for example, an electric heating wire.
It should be understood that the conversion module 4, the purge module 5, the heating module 6, the motorized swing bracket 12, the electromagnet, the refrigeration module 31, the weight sensor 32, etc. need to be connected to a single controller, which may be a single controller, such as a Programmable Logic Controller (PLC), or a laser dew point meter controller may also be used.
