ASPHALT SMOKE TREATMENT SYSTEM Russian patent published in 2022 - IPC B01D50/00 B01D53/44 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering and, in particular, to the asphalt smoke treatment system. The asphalt smoke treatment system contains an asphalt smoke collection device, made with the possibility of collecting asphalt smoke; an oil trap, including: a housing, a turbulence creation unit and a dust removal device. The housing has a cavity formed in it, and the specified housing is equipped with an inlet for asphalt smoke and an outlet that communicate with the specified cavity. The asphalt smoke inlet is connected to the exhaust end of the asphalt smoke collection device. The turbulence creation unit is located in the specified cavity, made of oleophobic material and designed to form turbulence of the fluid so that large oil droplets contained in asphalt smoke entering the cavity are dispersed into small oil droplets and contribute to the unification of oil droplets with dust in the cavity. The dust removal device is connected to the outlet and is designed to remove dust and a combination of dust and oil droplets. The turbulence creation unit contains at least the first two deflectors and a filler. The first two deflectors are permeable and located in the cavity between the inlet for asphalt smoke and the outlet. The filler is located between two adjacent of the specified at least two first deflectors in order to induce the fluid flowing past to form turbulence. By placing the oil trap between the asphalt smoke collection device and the dust removal device, oil droplets can, on the one hand, be cured in an advantageous way for their effective removal by the dust removal device, and, on the other hand, damage can be reduced, and direct ingress of oil droplets into the dust removal device and their adhesion to the dust removal device can be prevented, so that the dust removal device cannot be blocked, and the dust removal efficiency cannot be degraded.

EFFECT: expansion of the range of solutions for asphalt smoke treatment.
