nullIt is an object of the invention to be realized by techniques below scheme: a kind of centrifugal paving mist glance coal removal device，It is characterized in that，It includes: outer tank、Inner canister、Water pump、Blower fan、Liquidometer、Shower nozzle and liquid filter，It is built-in with tank in outer tank，Volume between outer tank and tank is exocoel，Tank internal volume is inner chamber，Outer tank arranges liquidometer，At the top of tank, shower nozzle is set，Described exocoel is connected by liquid filter with the water inlet of water pump，The outlet of water pump is connected with shower nozzle by sparge pipe，The inwall of tank upper end is equipped with the blast pipe of bias，It is provided with escape pipe at pot bottom，The air outlet of blower fan is by the inner space of blast pipe with tank，The pipe being connected with described exocoel is set on the top of outer tank，Pipe is connected with chimney by the pneumatic filter arranged on it，It is equipped with blow-off pipe in the bottom of described exocoel，Blow-off pipe is equipped with blowoff valve.

It is equipped with several apertures on the tube wall of described escape pipe, and several apertures of escape pipe directly connect with the aqueous phase of described outer intracavity.

The one of the present invention centrifugal paving mist glance coal removal device, it is capable of spraying spray water parcel asphalt smoke granule, centrifugal cyclone reduction asphalt smoke granule kinetic energy collecting asphalt smoke granule and the structure of air water cleaning removing asphalt smoke granule owing to being provided with, there is simple in construction, low cost, the advantages such as volume is little, being particularly well-suited to the removal operation of asphalt mixing plant Colophonium heating process medium pitch cigarette, treatment effect is good, environmentally safe.
