<p>The present invention relates to a dust removal device and method of a high-capacity filter bag house, and more specifically, to a dust removal device and method of a high-capacity filter bag house in which the high-capacity filter bag house has a plurality of dust chambers and the dust removal device of the filter bag house comprises: a dust removal apparatus controller which adjusts dust removal operations of each dust chamber; and a linkage controller which is configured to communicate with the dust removal apparatus controller of each dust chamber, and to control the overall dust removal of the filter bag house by adjusting a dust removal sequence among the respective dust chambers and adjusting the opening and closing rates and opening and closing time intervals of a flow control device that passes through each dust chamber, wherein the dust removal of the filter bag house is initiated when pressure loss of the filter bag house reaches a predetermined numerical value or according to predetermined time intervals designated by a user in advance, so that the dust removal operations may be performed sequentially in each dust chamber. At this point, the invention enables: the dust removal to be carried out after completely shutting out a flow that passes through the dust chambers which are the targets of dust removal in order to prevent dust removed right after the dust removal operations in each dust chamber from being immediately re-introduced into a dust collector filter; dust collection efficiency to be increased by allowing the flow to pass through the corresponding dust chambers by at most 50% of a normal flow if a predetermined time elapses after the dust removal, so that an initial dust collection layer is formed in the dust collector filter; the flow to be returned to the normal flow again after the predetermined time has elapsed; and said dust removal of the individual dust chambers to be performed in consecutive order in each dust chamber.</p> |
