[0002] As a special coal resource, pyrolysis of oil-rich coal is a key step in achieving efficient resource utilization. Through pyrolysis, oil-rich coal can be converted into a variety of products, including gas, liquid, and solid. Pyrolysis gases, including hydrogen, methane, and carbon monoxide, are important chemical raw materials and fuels.

[0003] The existing real-time monitoring device for the pyrolysis of oil-rich coal usually discharges the gas directly after the pyrolysis is completed, which is not convenient for the treatment of the discharged gas.
