Abstract

PURPOSE: To enable to automatically carry out treatment against dust leakage by arranging a detecting apparatus using a photoelectrical apparatus in the vicinity of a damper in an outlet of a waste gas of a bag filter.
CONSTITUTION: Outlet dampers 8aW8n are provided in outlets 5aW5n of bag filters 2aW2n and small pores 9a, 9b are drilled to a rear parts of said outlets. To said small pores 9a, 9b, a light projector 10a and a light receiver 10b of an photoelectric switch are arranged. The photoelectric switch is operated by light interception due to soot to automatically to close the inlet dampers 2a'2n and outlet dampers 8aW8n of the bag filters 2aW2n.
