摘要: The present invention relates to a device at a filter hose, forming part of a hose filter, whereby contaminated gases (7) are brought to flow into the filter hose (6) for depositing contaminants (9) on the outer side of the filter hose (6), whereby the gases are brought to flow out of the filter hose (6) to a clean-gas zone (11) through a sleeve (14), whereby at least one compressed-air nozzle (17) is provided in the clean-gas zone (11) at a distance from the sleeve (14) and adapted to guide a blow-like flow (18) of compressed air through the sleeve (14) into the filter hose (6) for momentarily expanding said hose and thereby loosen the contaminants (9) deposited on the outer side of the filter hose (6), and whereby the sleeve (14) has an end portion (14a) defining a compressed-air discharge zone (24) through which the compressed air flows from the sleeve (14) into the filter hose (6). In order to ensure that no unfavourable spaces are provided between the outer side of the sleeve (14) and the filter hose (6), said filter hose (6) engages and/or is connected to the end portion (14a) of the sleeve (14).
