Background

Sludge incineration is a process for sludge treatment, which utilizes an incinerator to heat and dry dewatered sludge and then oxidize organic matters in the sludge at high temperature, so that a large amount of sludge is incinerated into a small amount of ash. Has the advantages of high weight reduction rate, high treatment speed, complete harmlessness and the like for sludge incineration. When the sludge is incinerated, the sludge needs to be placed in an incinerator. Then completely incinerating the sludge under the condition of excessive air, wherein the water content of the final sludge after incineration is 0, polycyclic aromatic hydrocarbon pollutants are hardly existed in the sludge, and the content of other organic matters is also almost 0. The sludge incineration can be influenced by the water content of the sludge, the temperature in the incineration equipment, the residence time of the sludge in the incineration equipment, the air amount introduced into the incineration equipment and other factors, and the existing sludge incineration equipment is mainly designed on the air amount introduced into the incineration equipment, so that enough excess air is ensured to be in the incineration equipment.

In order to reduce the flue gas treatment cost of sludge combustion, the existing industrial sludge is basically doped with other combustible substances when being combusted, so that the industrial sludge generates more ash after being combusted, in order to facilitate the discharge of the ashes, the existing industrial sludge incineration equipment is provided with a grid plate in the furnace, sludge is burnt above the grid plate, ashes fall below the grid plate, but the sludge will decrease in volume during the combustion process, at which time also the small sludge, which is partly unburnt, will fall from the grid plate, when this small, partially unburnt sludge falls into the ash, it also causes the flame to extinguish due to lack of air, which results in the ash containing organic matter, resulting in the final discharge of ash with substandard contents of organic substances, which requires re-combustion in order to reach the standard contents of organic substances in the discharged ash, which seriously reduces the incineration efficiency of the sludge.
