To solve the problem of blockage in the exhaust pipe before adding carbon powder in traditional carbon powder adsorption and purification systems, the asphalt smoke high-efficiency adsorption and purification system adopts the "source adsorption" technology, which adds carbon powder to the starting end of the exhaust pipe of equipment or workstations (kneading machine, cooling machine, paste conveying and forming workstation) that produce large amounts of smoke and high concentration of asphalt smoke. The carbon powder absorbs and purifies the collected asphalt smoke in the first time, ensuring that there is no condensation of asphalt smoke and water vapor along the exhaust pipe. At the same time, it greatly prolongs the reaction time between carbon powder and asphalt smoke, thereby effectively improving the adsorption efficiency.
