Abstract

The filter comprises a vertical cylindrical vessel of metal mesh closed at each end and internally lined with the filter cloth. The top end of the filter has a fluid inlet and an opening through which passes a rotating hollow shaft coaxial with the cylinder. Suction parts are fitted to the ends of arms extending from this hollow shaft which extends to the base of the filter. At least one suction pad sweeps the filter cloth surface and at least one sweeps the base. The hollow shaft is connected outside the top of the filter to a motor with gear reducer to rotate the shaft and to a fan which draws air through the shaft. Inside the casing on the upper part of the shaft are two diametrically opposed arms at the ends of which are suction pads that sweep the whole of the filter cloth. On the lower part of the shaft are two diametrically opposed arms having suction pads that sweep the floor. The outlet of the fan is connected to a cyclone for dust removal. Filter is used for cleaning large volumes of dust-laded gases, e.g. flue gases. It is compact which gives a lower capital cost and can work continuously. Power consumption is low for the volumes handled.
