Asphalt mixing plant smoke and dust treatment equipment

The exhaust gas is absorbed and neutralized by a packed scrubbing tower and scrubbing solution (using fillers to increase the contact surface area) to remove harmful particulate matter from the exhaust gas. The exhaust gas is treated by gas-liquid reverse absorption through a packed scrubbing tower（downward）Small water droplets are generated by mist spraying, and the exhaust gas flows in reverse from the bottom of the tower to achieve gas-liquid contact. This treatment method can cool the exhaust gas temperature, regulate the gas, and remove particles. To ensure uniform distribution of gas in the tower and complete contact between gas and liquid, a well filled filter material should have a sparse surface, a larger free surface area to increase the residence time between gas and liquid. At the same time, the selection of filling filter materials should have appropriate gaps to reduce the resistance of gas upward, reduce the pressure drop of the washing tower, and then undergo defogging treatment（mist　eliminator）And then discharged into the atmosphere.
