System for extracting vapor and particulates from a flow of a liquid and an air stream

Method of washing a turbine engine, using a system comprising a funnel and a filter unit;

• an opening of the funnel being directed towards an outlet of the turbine;
• an outlet of the funnel being connected to an inlet of the filter unit, the filter unit comprising a housing, a first filter and a second filter, a ventilation unit and a filter unit outlet;
• 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;
• the method comprising:
• supplying a mixture of cleaning liquid and pressurized air in an inlet of the turbine engine;
• collecting, from the outlet of the turbine engine, in the opening of the funnel a flow of at least an air stream, the air stream comprising vapour and particulates;
• receiving the air stream at the inlet of the filter unit;
• 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;
• separating the vapour from the air stream in the first filter, and removing the particulates from the air stream in the second filter.
