In order to improve the removal efficiency of paint mist in the exhaust gas of a motorcycle factory and reduce the operation cost

a set of high efficiency and energy saving dust removal equipment combining dry and wet is developed

which is composed of venture dedustor

cyclone and bag filter. The engineering practice shows that the initial particle size of paint mist is mainly concentrated in 0.5-5 μm

and the initial concentration of paint mist is 25-30 mg/m~3. After mixed dust removal equipment

the counting filtration efficiency of particle size ≥0.3 μm

≥0.5 μm and ≥5 μm is respectively 89%

96% and99.9%

and the paint mist concentration is less than 1 mg/m~3

and the total removal efficiency is greater than 96% . The processing air volume of the equipment is 100 000 Nm~3/h

the replacement cost of the filter bag is 200 000 yuan a year

and the total pressure drop is not more than 2 800 Pa. The mixed dust removal equipment paint mist removal efficiency is high

low operation cost

suitable for popularization.
