摘要： Methods for treating a filter (2) for filtering particulate matter from exhaust gas are disclosed in which a dry powder (4) is sprayed towards an inlet face of the filter (2) entrained in a primary flow of gas to pass through the inlet face to contact a porous structure of the filter. The back pressure of the filter (2) is monitored during spraying of the dry powder (4) and the spraying of the dry powder (4) is stopped when a back pressure of the filter (2) reaches a required value. The required value may equal an absolute back pressure, or a pre- determined target back pressure for the filter minus an offset pressure, or an estimated back pressure of the filter.

摘要： A powder spraying system comprises a source of dry powder (4), a spray nozzle (25), and a supply conduit (16) connecting the source of dry powder with the spray nozzle. The spray nozzle comprises a nozzle body (50) having a nozzle outlet (51), a first conduit (52) for dry powder, and a second conduit (53) for gas. The first conduit extends between a powder inlet (54) in communication with the supply conduit and a powder outlet (55). The second conduit extends between a gas inlet (56) and a gas outlet (57), the gas outlet being located in proximity to the powder outlet such that a gas flowing through the second conduit and out of the gas outlet produces a suction force at the powder outlet to promote flow of a dry powder through the first conduit and out of the powder outlet and the nozzle outlet. The powder outlet and the gas outlet are orientated to promote mixing of the gas with the dry powder. The first conduit (52) is a straight conduit between the powder inlet (54) and the powder outlet (55).

摘要： A method and apparatus (1) for treating a filter (2) for filtering particulate matter from 5 exhaust gas and a treated filter (2) are described. A reservoir (3) containing a dry powder (4) is provided. A vacuum generator (6) establishes a primary gas flow through a porous structure of the filter (2) by applying a pressure reduction to an outlet face of the filter (2). A spray device (7) receives the dry powder (4) from a transport device (8) and sprays the dry powder (4) towards the inlet face of the filter (2). A controller (9) is configured to control 10 operation of at least the vacuum generator (6) and the spray device (7). The dry powder (4) comprises or consists of a metal compound for forming by thermal decomposition a metal oxide.
