Description

[0002] Methane is an organic compound widely distributed in nature. It is a major component of natural gas, biogas, and pit gas, commonly known as gas. It can be used as a fuel and as a raw material for the production of substances such as hydrogen, carbon black, carbon monoxide, acetylene, hydrocyanic acid, and formaldehyde. Methane is widely used in industrial production and daily life. However, due to its potential to cause safety accidents, it is necessary to detect methane in practice. Traditional detection methods involve directly passing methane through a single-function detection device to test various indicators.

[0021] like Figure 1 As shown, a methane detection device includes a main frame 1, in which several detection gas cell assemblies 2 are installed, a current display meter 3 and a test board 4 are fixedly installed on the upper end of the main frame 1, a collection plate 5 is fixedly installed in the main frame 1, a flow meter 6, a voltage display meter 7 and a main power switch 8 are fixedly installed on one side of the main frame 1, a bottom cover 9 is threadedly installed on the lower end of the main frame 1, a support leg 10 is fixedly provided at the lower end of the bottom cover 9, and a detected module 11 is plugged and installed on the detection gas cell assembly 2.

[0022] The current display meter 3 is used to measure the current of the detected module 11 during operation. The flow meter 6 is used to measure the flow rate of methane entering the overall device. The voltage display meter 7 is used to measure the voltage of the overall device during operation. The main power switch 8 is used to control the power on and off of the overall device. The detected module 11 is used to detect the methane concentration passing through the detection gas cell assembly 2. It should be noted that the side ends of the main frame 1 are provided with heat dissipation holes. The test board 4 and the assembly board 5 are used to convert the serial port protocol of the detected module 11 into a USB protocol for input into the computer.

[0023] like Figure 2 As shown, the detection gas cell assembly 2 includes a connecting body 16, the upper end of which is fixedly provided with a mounting platform 12, and the mounting platform 12 is provided with a socket. The upper end of the mounting platform 12 is fixedly provided with a sealing ring 13, the side end of the connecting body 16 is fixedly provided with a first air pipe joint 14, and the lower end of the connecting body 16 is fixedly provided with a second air pipe joint 15, and the first air pipe joint 14 and the second air pipe joint 15 are both connected to the connecting body 16.

[0025] like Figure 4 As shown here, a specific example is shown, with four parallel branches. Methane enters from the main air inlet, is split into four branches, and flows into the A, B, C, and D air inlets (the air pipes closest to the main air inlet). After passing through the four-way series gas pool, it is combined and flows out of the A', B', C', and D' outlets (the air pipes farthest from the main air inlet) through the main outlet.
