The utility model discloses a hot plate furnace + cement kiln is dealt with dry mud technique in coordination. The hot plate furnace is embedded in the conical part of the decomposing furnace, the dry sludge is firstly screened and crushed for pretreatment, uniform sludge particles are conveyed into the hot plate furnace for combustion, the dry sludge can stay in the hot plate furnace for 45min at the longest time, the full combustion is almost achieved, the flue gas after the dry sludge is combusted enters the decomposing furnace, and a small amount of large-particle sintering slag enters the cement kiln to be made into clinker. The influence of the dry sludge on the stability of the kiln system is greatly reduced, the dry sludge treatment amount can also be greatly increased, and the maximum treatment amount can reach 600 t/d.
The utility model has the advantages that: because a large amount of microorganisms still survive in the dry sludge, the sludge is hardened due to fermentation in the process of stockpiling. Consequently the utility model discloses carry out the preliminary treatment to dry mud, mud enters breakage and screening back, and the granule degree of consistency is better, and the burning is more abundant.
