Construction and Operation of Anti-pollution Facilities

(1) Exhaust cylinder of roasting workshop: The exhaust gas of the workshop is first destocked by the destocking facility in the SNCR furnace, and then enters the pre-dust for dust removal through the closed flue. Desulfurization removes sulfur dioxide in the flue gas, and finally further dust is removed by a wet electrostatic precipitator, and the facilities are operating normally. The purified flue gas is discharged through a 77-meter chimney.

(2) Exhaust cylinder for forming electric tar catcher: Asphalt smoke generated during the process of asphalt heat preservation and kneading and molding is collected and transported to the electric tar catcher through a closed pipe for processing, and the facility operates normally. The purified flue gas is discharged through a 26-meter-high chimney.
