Background technology
Oxidizing process produces Colophonium, be with residual oil, solvent deoiling Colophonium or its concoction with other soft components as raw material,
In bubble type oxidizing tower, at a certain temperature, air is continuously passed through.Asphalt stock is stopped certain time in oxidizing tower, with sky
There is oxidation reaction in gas, increased asphalt content, improve its softening point, reduce needle penetration, up-to-standard so as to obtain
Asphaltic products.
In bitumen blowing tower, air is blown into from bottom of towe, passes through liquid phase asphalt stock layer, the oxygen of in the air in the form of bubbles
The reaction that the reaction such as complicated oxidation, dehydrogenation, generation is occurred with asphalt stock is reacted for gas-liquid bubble type.Air distributor is for combing
Formula, radial or ring-type, air is sprayed in Colophonium by nozzle, in order that air is uniformly distributed in oxidizing tower, nozzle diameter one
As be 10～16mm, spout air velocity is that 5～10m/s, nozzle arrangement strictly need to design.But in operation process, often
Cause air skewness because of nozzle segment coking, in order to nozzle coking is prevented, nozzle diameter can not be too small, so causes
The air bubble of ejection is relatively large in diameter, so as to reducing the utilization rate of air and extending oxidization time.As bubble is gradually increasing,
Static pressure is gradually lowered, and minute bubbles converge and accumulate into increasing bubble and cause the heat transfer of air and Colophonium, mass transfer interface to gradually decrease,
The oxygen of bubble surface is just consumed quickly, and the oxygen inside bubble is not utilized well.
