Definitions

  • the present invention relates to a process for the auto-thermal incineration of sludge from urban and / or industrial water treatment plants. According to a second aspect of this invention, this method can be implemented so as to simultaneously incinerate such sludge and household waste.
  • the present invention proposes to provide a process which can be implemented in an extremely compact installation, which in particular makes it possible to reduce operating and maintenance costs, and to carry out automation, with relatively simple means, of all the operations leading to this auto-thermal incineration of the sludge, possibly simultaneously with household waste.
  • the present invention proposes to improve the method mentioned above lastly.
  • the invention relates to a process for the auto-thermal incineration of sludge from urban and / or industrial water treatment plants, characterized in that it consists in carrying out dewatering the sludge by centrifugation-drying, using the sensible heat of the fumes from the incineration furnace, said dehydrated sludge and in pulverulent form being introduced into the incineration furnace.
  • this invention relates to a process for the auto-thermal incineration of sludge from urban and / or industrial water treatment plants and household waste, characterized in that it consists in dehydrating the sludge by centrifugation-drying using the sensible heat of the fumes from the incineration furnace, said dehydrated sludge being introduced, in powder form, into the incineration furnace at the same time as household waste.
  • the sludge from the centrifugation-drying stage can be reintroduced into the incineration oven in order to destroy the incondensables and recirculate the combustion and dilution air necessary.
  • the fumes from the incineration oven are diluted before the centrifugation-drying step, by introduction of dilution air.
  • the fumes from the incineration oven are conditioned before recovery of their sensible heat during the centrifugation-drying step of the sludge, this conditioning, carried out in a reaction chamber, simultaneously ensuring a pre-dusting and a recrystallization of the purges coming from the final stage of smoke treatment.
  • the combustion gases from the incineration furnace are used to dry the liquid sludge, which is simultaneously subjected to centrifugation to obtain a high degree of dryness (greater than 65 %).
  • the dried sludge, reduced to a pulverulent state, is introduced into the incineration furnace at the same time as household waste.
  • the fumes and mists resulting from drying are then subjected to a treatment which may be conventional.
  • the method according to the present invention makes it possible to treat sludge and household waste simultaneously, according to an unlimited weight ratio, which is not the case with previously known methods.
  • a dilution of the fumes leaving the incinerator 10 is carried out using an air flow, which lowers the temperature of the fumes from 900 to around 200 ° C. while retaining the sensible heat, the energy required for drying being taken from this sensible heat as already mentioned.
  • the dilution chamber 12 serves both as a pre-dust collector and as a crystallization chamber for the purges originating from the final treatment of the fumes, these purges being introduced at 22 into the chamber 12 at from the processing unit 20, which makes it possible to dilute and eliminate solid pollution.
  • the vapors which come from the drying of the sludge in the dryer-centrifuge 16 can be reintroduced into the incineration oven 10, in order to destroy the incondensables and to recirculate the combustion and dilution air necessary while also making it possible to use the sensible heat contained in these vapors, which can make it possible to avoid preheating of the combustion and / or fluidization air when the incineration oven 10 is a fluidized bed oven.
