Abstract

The invention provides a sludge drying and incinerating process. According to the sludge drying and incinerating process, gas exhausted from a drying furnace is led into a hot air generating furnace and an incinerating furnace, so that the gas with a certain humidity is led into the hot air generating furnace and the incinerating furnace; the specific heat capacity of hot gas and high-temperature gas is improved, the thermal energy carried by the hot gas and the high-temperature gas is increased, and the thermal efficiency is improved. In addition, the gas exhausted from the drying furnace is burnt again in the hot air generating furnace and the incinerating furnace so that the thermal energy of retorting gas can be fully utilized, and smelly gas can be removed; the gas generated in the incinerating furnace can also enable the gas generated in the incinerating furnace to be led into the drying furnace to be burned when being led into the drying furnace, and the thermal energy carried by the gas exhausted from the incinerating furnace can be fully utilized. Through the mode, energy consumption in the whole drying and incinerating process is greatly lowered, and meanwhile the efficiency of drying and incinerating is improved.

Description

technical field [0001] The invention relates to the technical field of pollutant treatment equipment, in particular to a sludge drying and incineration process. Background technique [0002] At present, domestic and foreign sludge treatment and disposal methods mainly include landfill, incineration, and land utilization. Sludge landfills occupy a large amount of land, and the leachate and gas produced will seriously pollute groundwater and the atmosphere. When land is used, because the sludge contains pathogenic bacteria, parasite eggs, heavy metals and various refractory organic compounds, it will endanger human health and the growth of animals and plants. Incineration is the most thorough means to realize the harmlessness, reduction and stabilization of sludge, and its proportion in sludge treatment and disposal is increasing year by year. It has become the main technology adopted by developed countries, but its technology and equipment investment is large. The operating...
