AI Technical Summary
Existing asphalt fume purification devices have low purification efficiency and cannot effectively remove harmful substances such as tar particles and benzo[a]pyrene from asphalt fumes.
Design an asphalt fume purification device comprising a housing, partitions, activated carbon mesh, and an oil washing spray assembly. The device achieves full contact between the sprayed atomized washing oil and the high-temperature asphalt fume. Utilizing the activated carbon mesh adsorbent and an electric heater, the gas flow path is extended, ensuring sufficient contact and reaction between the high-temperature asphalt fume entering the housing and the atomized washing oil. An electric heater is fixedly installed on the top of the electric heater, ensuring that the gas enters the housing from the inlet.
It effectively improves the purification efficiency of asphalt fumes, reduces the emission of harmful substances, and protects the environment and human health.
