摘要： The present invention relates to an electrostatic precipitator (ESP) system (1) for removal of particles from a flue gas flowing in a flow passage (4) being delimited by a primary collection in the form of a collection plate (5). The system comprises a discharge electrode (11) arranged in the flow passage and connected to a high voltage generator (12) providing for an electric field around the discharge electrode. The system further has a secondary collection electrode in the form of a grid (101) arranged within the collection plate and made of an electrically conductive material. The presence of such a grid improves the efficiency of the precipitator. In some embodiments, the ESP system comprises an actuator (112) for moving the grid upwards and letting it drop onto an internal bottom structure (109). The movement between the collection plate and the grid as well as the impact force imparted to the dropping grid both result in a removal of collected particles.

摘要： A ventilator (10) includes a casing (20) which includes an inlet (21) for outdoor air, an inlet (22) for indoor air, and an air outlet (23), and an air-blowing fan (30) contained in the casing (20). The ventilator (10) is configured to suck the outdoor air and the indoor air through the corresponding inlets (21, 22) into the casing (20) by using the air-blowing fan (30), process the sucked air, and supply the processed air through the outlet (23) into a room. An electrical dust collecting mechanism (40) is provided in the casing (20) to remove dust in the sucked air. Furthermore, a deodorizing mechanism (50) having a low resistance to air circulation is provided in the casing (20) to remove an odorous substance in the sucked air.

摘要： A method for removing particulate matter from a particulate-bearing gas stream includes flowing a particulate-bearing gas stream at a first volumetric flow rate to a plurality of ESP units; producing electrically charged particulate matter; collecting electrically charged particulate matter on collection electrode plates; reducing the flow through at least one of the ESP units; sequentially increasing the flow through one or more remaining ESP units in an amount so as to maintain the sum of flow through all of the ESP units at the first volumetric flow rate; subjecting the collection electrode plates in the at least one ESP unit with reduced flow to forces which dislodge the particulate matter from the collection electrode plates; collecting the dislodged particulate matter in a particulate collection receptacle; and withdrawing a gas stream of reduced particulate matter contamination.
