<p>PURPOSE:To effectively perform destruction of inflammable particles by fire and removal thereof by providing an injector for injecting a solution on the upstream side of a particulate filter in an exhaust path, said solution promoting the combustion of inflammable particles to be collected on said filter. CONSTITUTION:The captioned waste gas purification device includes a particulate filter 14 for capturing and collecting inflammable particles in a exhaust path 12 and an injector 16 disposed on the exhaust path 12 slightly upstream of said filter 14 for injecting a catalyst solution to promote the combustion of inflammable particles. The injector 16 is connected with a measurement tank 20 through a solution supply path 22 via a solenoid valve 18. The measurement tank 20 has a volume capable of housing a required amount of the solution corresponding to one time of a regeneration process of the filter 14, and is connected with a solution reservoir tank 32 through a solution path 24 via a three-way changeover solenoid valve 28 and a filter 30. Furthermore a butterfly valve 40 is provided in the vicinity of the injector 16 of the exhaust path 12 for closing the valve in filter regeneration.</p> |
