Abstract:
1. A system for extracting vapor and particulates from a flow of at least an air stream, the air stream comprising vapor and particulates, the system comprising: a funnel and a filter unit, an opening of the funnel being arranged for receiving the flow of at least the air stream; an outlet of the funnel being connected to an inlet of the filter unit, the inlet of the filter unit being arranged for receiving the air stream, wherein; the filter unit further comprises a housing, a first filter and a second filter, a ventilation unit and a filter unit outlet, the first filter being a vapor separation filter comprising an adsorbent filter, the second filter being a particulate air filter; the housing comprising a first, second and third chamber; the first chamber and second chamber being separated by the first filter, the second chamber and third chamber being separated by the second filter; the inlet of the filter unit being located in the first chamber; the ventilation unit being located between the third chamber and the filter unit outlet and being arranged during use for creating an underpressure in the first, second and third chambers, the underpressure being relative to a pressure at the inlet of the funnel to cause the air stream to enter the inlet of the filter unit and wherein the first filter is arranged for separating extracting the vapor from the air stream and the second filter is arranged for removal of the particulates from the air stream; wherein the flow of at least the air stream further comprises a flow of liquid and wherein the funnel comprises between the opening of the funnel and the inlet of the filter unit, an inclined surface in a lower portion which is arranged for obstructing the flow of the liquid towards the outlet of the funnel and for returning the obstructed liquid to the opening of the funnel for streaming out from the opening of the funnel.
