A demister includes demister filters that are rinsed in place with sprayed liquid during the normal operation of the demister. The filters remain in place and the demister continues to operate during the rinsing process. The disclosure also provides a method of rinsing the filters during the continued operation of the demister. The demister filters that can be moved between an operational position to an extended cleaning position where they can be cleaned without fully removing them from the demister. The filters are slid out through an open door to provide access for cleaning. The disclosure also provides a method of moving the filters out of the demister to extended positions and cleaning the filters in the extended positions.

A system for cleaning a filter mounted over an intake opening of an air handling unit. A conduit is secured to an elevated location of the unit and includes a plurality of spaced nozzles arrayed against the filter. A supply tube connects to the conduit for supplying a pressurized fluid through the nozzles in order to clear debris from an exterior of the mounted filter. The pressurized fluid includes either of a liquid (typically water) or a compressed air provided from any of a source or a supply reservoir. A pump is incorporated into the supply tube for pressurizing the fluid. A filter incorporated into the supply tube filters the pressurized fluid prior to delivery to spray issuing conduit. A processor/controller is provided in combination with an arrangement of control valves for providing timed sequenced washing of the filters. A collection basin is provided for recycling used liquid for re-delivery and re-use through the spray delivery conduits.

A dust collector is provided, comprising a base (1), wherein a filtering barrel (9) is installed on the upper part of the base (1), one side of the filtering barrel (9) is provided with a main fan (21), a main fan air inlet (22) extends to the inside of the filtering barrel (9) through the outer wall of the filtering barrel (9), the upper section of the filtering barrel (9) is provided with a partition plate (23) for isolating the inside of the filtering barrel (9) from top to bottom, the partition plate (23) is provided with a plurality of through holes, the main fan air inlet (22) is connected with one of the through holes, filtering devices (24) are installed in other through holes, a straight pipe (16) is installed on the upper part of the partition plate (23), the surface of the straight pipe (16) is provided with first blowback pipes (25), each of the first blowback pipes (25) faces a filtering device (24), the upper part of the straight pipe (16) is provided with a bent pipe (15), the surface of the bent pipe (15) is provided with a second blowback pipe (26), the second blowback pipe (26) passes through the partition plate (23), the upper part of the partition plate (23) is hermetically isolated, the bent pipe (15) and the straight pipe (16) are communicated with an air storage device, respectively, one side of the filtering barrel (9) is provided with an air suction port (13), the end of the air suction port (13) is provided with a third valve (131), and the lower part of the filtering barrel (9) is provided with a fourth valve (12). When the dust collector is not stopped, a dust collecting bag (304) can be replaced, which is time-saving and high in working efficiency. Using two sets of blowback systems, it is easy to clean the dust residue. Using two sets of dust collecting system, the dust collection will be not affected when blowing back. A hydraulic rod (8) is installed to facilitate transportation and movement.

The present invention is a highly efficient and easily shippable drum filter device comprising segmented filter media, easy to manufacture light-weight drum segments or torsional tensioning elements. Preferably, it comprises bulged side wall, that can be fitted after shipment and that can be readily opened for easy access to the filter. The drum filter device can be incorporated into a filtering system further.

A laundry appliance includes a blower that delivers process air through an airflow path, an air filter having a filter media that separates particulate from the process air to define captured particulate, a fluid spray system having at least one cleaning nozzle and a carrier nozzle, and a sump that receives the stream of carrier fluid, the cleaning stream and the captured particulate. The carrier nozzle delivers a stream of carrier fluid below the air filter, and the at least one cleaning nozzle directs a cleaning stream onto the filter media. The cleaning nozzle operates after activation of the carrier nozzle to direct the captured particulate into the stream of carrier fluid.
