Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a device for recycling waste gas. Background Art

[0002] Because wastewater tanks remain sealed for extended periods, toxic, flammable, and explosive gases can easily form inside them. Existing olefin wastewater tanks are designed with low internal pressure, allowing gaseous hydrocarbons at the top of the tank to easily escape through the breather valve. This exhaust gas accumulates around the tank, creating a strong odor and posing a safety risk. Furthermore, the high concentration of water vapor in the waste gas can easily pollute the environment. Current waste gas treatment methods primarily rely on discharge or simple treatment, lacking effective resource recovery and utilization methods.

[0003] In order to solve the above problems, there is an urgent need for a waste gas recovery and utilization device that can effectively remove the waste gas in the wastewater tank and improve the utilization rate of the waste heat of the incinerator to reduce environmental pollution and improve resource utilization.
