[0002] Industrial waste is generally divided into two categories: solid waste and liquid waste. Currently, the market uses combustion furnaces to treat liquid waste.

[0003] The waste liquid is burned at high temperature in the waste liquid combustion furnace. The waste liquid sprayed in the form of steam mist is fully exposed to the high-temperature rotating rising flue gas in the combustion furnace. The water in the waste liquid is heated and evaporated. Most of the toxic and harmful substances in the waste liquid are completely burned and burned out at high temperature to produce a large amount of smoke, CO2, and various corresponding acidic gases. Most of them enter the secondary combustion chamber. By adjusting the combustion environment in the secondary combustion chamber, complete combustion is ensured while effectively controlling the production of dioxins. The common way is to introduce a large amount of air into the secondary combustion chamber. However, the common way of introducing air cannot be fully combined with the combustion material, and it is difficult to effectively achieve air distribution at the combustion position, resulting in the production of a large amount of carbon monoxide.
