Baghouse operation after a period of time should be timely cleaning ventilation ducts, must not undermine the primary layer circular ventilation ducts when cleaning, so efficiency. Hangzhou ventilation duct installation process when high dust concentrations of gas, in order to avoid frequent cleaning bag filter bag damage caused by smoke ventilation ducts, with pre-filter should be pre-purified. First layer: The dusty gas through the filter, as they further filter inside, so that the space between the fibers decreases and eventually form attached to the filter surface of the dust layer. Smoke management in galvanized iron duct works are made of galvanized steel production. Pipe insulation materials are selected through local fire department approved non-combustible insulation materials.
