[0002] 1,4-Butanediol is an organic compound, appearing as a colorless or pale yellow oily liquid. It is used as a solvent and humectant, and also in the manufacture of plasticizers, pharmaceuticals, polyester resins, and polyurethane resins. During 1,4-butanediol production, various stages generate flammable waste liquids and gases. These flammable substances must be removed before further processing and discharge. Waste heat treatment is performed during this process, but without a mixing device, the waste heat recovery efficiency is low.

The device includes a waste gas treatment system comprising a combustion furnace and a waste heat recovery device connected to the combustion furnace. A dust collector is installed on one side of the waste heat recovery device. Waste liquids and waste gases generated in various stages of the factory are piped into the combustion furnace and ignited by the combustion section to burn off the combustible materials.
