Abstract
PURPOSE: To greatly save the consumption of fuel necessary for heating and evaporation of night soil, by recorvering and re-using the heat of high temperature combustion gas containing steam of night soil, in a night soil evaporating and combustion equipment.
CONSTITUTION: Night soil 12 is pretreated 1 to remove dirt, shives and specks 7, and is introduced into a preheater 2 together with air 13. The mixture of air 13 and night soil 12 is heat-exchanged with combustion gas, and is preheated to about 70W 95°C, then enters a separator 3. In the separator 3, the mixture is separated into air and condensate 8 containing gas fluid such as steam and solid matter. The gas matter enters a heat exchanger 4, and is heat-exchanged with the high temperature combustion gas released from an incinerator 5, and is further elevated in temperature to enter the incinerator 5. In the incinerator 5, dirt, shives and specks 7 removed in the pretreatment, and the condensate 8 from the separator 3 are complately burnt at 600W1000°C, using heavy oil as fuel oil additive, so that the organic substance, inorganic substance, and offensive odor components in the night soil are oxidized and decomposed. The waste gas from the incinerator 5 is, after removing dust in a cyclone 6, is re-used in heating and evaporation of the night soil and air through heat exchangers 4, 2.
