<p>PURPOSE:To provide a waste gas treating method using a filter type dust collector where pressure fluctuation in a place to which a desalting agent is fed, etc., is reduced to perform stable desalting operation. CONSTITUTION:In a waste gas treating method where after a desalting agent is sprayed into a waste gas flue 11 by using carrying air to react it with acidic components contained in waste gas 13, the reaction product is collected by a bag filter 12, the desalting agent is intermittently fed and also on the stoppage of spraying the desalting agent, the collected dust on the bag filter 12 is shaken down. In this way, the pressure fluctuation in the waste gas flue is restricted to perform stable desalting operation and also the desalting agent is made effective use of.</p> |
