Embodiment Construction
[0023] The present invention is further described below in conjunction with embodiment. The scope of the present invention is not limited by these Examples.
[0024] The schematic diagram of online pretreatment device for sample gas of ethylene cracking furnace of the present invention is shown in figure 1 , the way of use is: confirm that the vortex cooler of the cracking furnace is in the closed state. After the installation of the device is completed, all the on-off valves are in the off state. First, confirm that the three-way switching valve 9 is in the B position and then open the on-off valve 10, and the medium-pressure steam 12 enters the heating pipeline Heat the device, and after 10 minutes of stabilization, open the switch valve 1 and turn on the cracking furnace vortex cooler, the sample gas 11 enters the ethylene cracking furnace sample gas online pretreatment device and passes through the liquid accumulation tank 2, the gas filter 6, and the pressure gauge 7 in s...
