Abstract

PURPOSE: To reduce the whole quantity of the treating liquid and reduce the operation cost of the apparatus, by spraying the thick slurry of the sludge cake or the water extraction liquid of incinerated dust of the sludge cake to gas generated from the city refuse furnace.
CONSTITUTION: After high-temperature waste gas generated from city refuse furnace 1 is led into cyclone 2 go separate coarse dust, it is led to reaction tower 3 and is brought into contact with the alkali absorbing liquid sprayed from spray nozzle 4 and is cooled, and simultaneously, harmful gas such as Cl, HCl, SOX, and so on is caused to react on the alkali absorbing liquid and is made into dust and is led into electric dust collector 5. As the alkali absorbing liquid, the thick slurry of the sludge cake obtained by treating waste water by a lime-system flocculant or the water extraction liquid of incinerated dust obtained by incinerating this sludge cake is used.
