| Research Abstract |
The improvement of lifetime of bag-filter in a dust collector of the waste incinerator is investigated. The bag-filter is used widely to remove the toxic substance, especially dioxins included in the exhaust gas by passing through the filter cloth. To prevent the hazardous matter from scattering into the environs due to the failure of the bag-filter in operation, a reliable method for prediction of lifetime of the bag-filter is needed. Flow visualization and an analysis of computational fluid dynamics to make clear the fiber abrasion mechanism due to gas-particle two-phase flow through the model of bag-filter are performed.
