Disclosed is a flow-type energy storage device having an improved flow of fluid. The flow-type energy storage device stores electricity using a fluidic material, and includes a reaction region in which charge-discharge reaction of electricity is performed by the fluidic material, wherein the reaction region has an octagonal cross-section. The shape of the reaction region is controlled to thus improve the flowability of the fluidic material, thereby providing a flow-type energy storage device that has almost constant electrical properties even when a charging and discharging cycle is repeatedly performed. Further, the structures of an inlet and an outlet are not complicated and a separate part for controlling the flow of fluid is not used in the device, and accordingly, additional costs are not incurred during a process of manufacturing the flow-type energy storage device.

The present invention provides a dust collector which includes a chamber divided into an inlet chamber and a discharge chamber by a barrier, and a bag filter which is installed inside of the inlet chamber, and is formed in a shape having an inner space and an opening part by a filter medium, so as to communicate with the discharge chamber through the opening part, wherein a treatment gas is introduced into the inlet chamber and is filtered while passing through the filter medium of the bag filter, then moves to the discharge chamber through the opening part to be discharged, and the bag filter has air permeability decreased toward the opening part. According to the bag filter and the dust collector, it is possible to achieve a high collection performance and a stable operation even when using a long bag filter due to improvement of uniformity of the filtration velocity along the length of the bag filter.
