Soot treating apparatus for dust collector

Abstract

A hopper for collecting soot included in the exhaust gasses is disposed on a lower portion of a filter. There is a backwashing means for introducing a compressed air into the filter from the exhaust gas-downstream side through an air conduit and dropping the soot deposited in the filter on to the hopper. A combustion pipe is disposed on a lower end of the hopper, and an air nozzle for supplying a combustion air is disposed in the combustion pipe. A combustion medium which is capable of collecting the soot arriving at the combustion pipe and the burned ashes and of letting the combustion air pass therethrough is inserted detachably into the combustion pipe and arranged on a porous ceramic plate. A heater is disposed around the combustion pipe for burning the soot which is collected by the combustion medium. The soot is burned completely at the combustion medium, and most of the ashes remain at the combustion medium and the rest of the ashes is completely collected by the plate. Whereby the combustion gasses can be directly discharged to the atmosphere. The ashes can be easily dumped by renewing the combustion medium and the plate.
