The invention relates to a waste heat recovery system for sludge treatment. The waste heat recovery system for sludge treatment comprises a waste heat boiler and a secondary combustion chamber gas connecting pipeline, wherein a slag hearth is arranged at the lower end of the interior of the waste heat boiler, a blowdown continuous blowdown flash tank is arranged at the upper end of the interior ofthe waste heat boiler, one side of the waste heat boiler communicates with the secondary combustion chamber gas connecting pipeline through a pipeline, electric hoists are distributed at the top of the upper end of the waste heat boiler, the upper end of the blowdown continuous blowdown flash tank communicates with a boiler dosing tank through a pipeline, the boiler dosing tank communicates witha drain cooler A through a pipeline, and the drain cooler A communicates with a drain cooler B through a pipeline. Compared with the prior art, the waste heat recovery system has the beneficial effects that certain calorific value for sludge and leftover materials, waste heat can be recovered by means of the waste heat boiler system and supplied in a steam mode on the premise that the incinerationrequirement is met, meanwhile, the front section of the system is about sludge drying, the steam demand is large, and therefore, gradient utilization is realized to the greatest extent in the aspectof waste heat utilization.
Description
technical field [0001] The invention relates to the technical field of sludge treatment waste heat utilization, in particular to a waste heat recovery system for sludge treatment. Background technique [0002] Sludge treatment is the process of thickening, regulating, dehydrating, stabilizing, drying or incinerating sludge. There are many methods that can be used to treat oily sludge. Chemical and physical methods such as incineration, chlorine oxidation, ozone oxidation and combustion, biological treatment methods such as bioremediation, traditional composting, etc. After the sludge treatment is fully burned by the front-end rotary kiln and the second combustion chamber, the temperature of the flue gas is about 850°C, and it enters the waste heat boiler for waste heat recovery. The waste heat recovery generates electricity and generates green energy, which meets the national demand. [0003] The existing waste heat recovery system cannot be used in a gradient application,...
