Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge calorific value conditioning machine. Background Art

[0002] Sludge incineration is a sludge treatment process. It uses an incinerator to heat and dry the dehydrated sludge, and then uses high temperature to oxidize the organic matter in the sludge to turn the sludge into a small amount of ash. Before the sludge enters the furnace for combustion, it is necessary to dehydrate the sludge without losing the organic matter in the sludge, to ensure that the sludge has sufficient calorific value and meet the boiler's requirements for the fuel entering the furnace for combustion. Traditional sludge dehydration methods include natural drying, granulation dehydration and mechanical dehydration.
