This invention belongs to the field of waste gas treatment technology, specifically disclosing a flare gas incineration treatment system for EVA production. The system includes a daily gas buffer tank and an emergency gas buffer tank, each connected in series with a liquid separator, a water seal tank, and a cooler. The gas outlets of the two coolers are connected to an incinerator, and the flue gas outlet of the incinerator is connected in series with an induced draft fan and a chimney. Addressing the safety risks, such as explosions, posed by direct combustion of flare gas generated during EVA production, this invention achieves safe, efficient, and compliant emissions of flare gas by classifying and collecting the flare gas, separating it into liquids, applying a water seal, pre-treating it with cooling, and precisely monitoring key parameters, combined with efficient incineration in an incinerator. This solves the problem that direct combustion of flare gas containing hydrocarbons such as ethylene, vinyl acetate, and organic solvents generated during EVA production can easily lead to explosions or flameout accidents due to gas composition imbalance.

This utility model discloses a combustion chamber for a regenerable coated sand roasting furnace, comprising a combustion chamber body, multiple burners at the top of the combustion chamber body, a conveying shaft with bearings inside the combustion chamber body, and a drive structure in cooperation with the conveying shaft. The conveying shaft has spiral conveying blades, and both ends of the conveying shaft extend outward to the outside of the combustion chamber body, with conveying grooves formed therein. A medium conveying pipe is connected to the conveying grooves via sealed bearings. A heat exchange chamber is provided on the spiral conveying blades, communicating with the conveying grooves. A sand storage box is located at the top of the combustion chamber body, and a sand drop control structure is provided between the bottom of the sand storage box and the combustion chamber body. A medium conveying pipe at the output end is spirally wound around the outside of the sand storage box to form a preheating section. This utility model can preheat the sand core to be coated, while improving the fullness and uniformity of heating.
