- the volume of the incinerator 16 is about 3 liters, the outer diameter of the incinerator 14 is 310 mm, the heater capacity of the incinerator 15 is 2800 W, the set temperature is 570 ° C., the deodorizing catalyst filling section 20 is 130 mm wide, 72 mm high, and thick 12 mm, the deodorizing catalyst is a commercially available palladium catalyst, the filling amount is 110 cm 3 , the exhaust blower 19 has an exhaust capacity of 4 m 3 per minute, the smoke filling material filling part 21 is 130 mm wide, 72 mm high, 160 mm long, The heater capacity of the filling heater 22 is 450 W, the set temperature is 590 ° C., the soot removal filling is a commercially available zeolite A049, the filling amount is 1300 cm 3 (about 750 g), and the incineration processing temperature detector 34 is set to end the incineration process.
- the temperature is 150 ° C.
- the exhaust blower stop set temperature of the incinerator upper temperature detector 32 is 54 ° C.
- the basic structure of the electric incinerator is the same as that of the electric incinerator used in Example 1.
- the incineration process was started by dropping 1476 g of urine and 524 g of stool together with 10 sheets of paper into the incineration container 16. 15 minutes after the start, the surface temperature of the filler heater 22 rose to 590 ° C., and the incinerator heater 15 and the exhaust blower 19 started operating. Further, after 13 minutes, the surface temperature of the incinerator heater 15 reached 570 ° C. For a while after the start of the operation of the incinerator 15 and the exhaust blower 19, the amount of urine was so large that a slight ammonia odor was felt in the gas discharged from the exhaust port 23, but it was not uncomfortable. . In addition, no smoke emission was observed, but we felt wetness due to evaporation of moisture.
- the volume of the incinerator 16 is about 3 liters, the outer diameter of the incinerator 14 is 310 mm, the heater capacity of the incinerator 15 is 2800 W, the set temperature is 570 ° C., the deodorizing catalyst filling section 20 is 180 mm wide, 100 mm high, thick 24 mm, the deodorizing catalyst is a commercially available palladium catalyst, the filling amount is 450 cm 3 , the exhaust blower 19 has an exhaust capacity of 4 m 3 per minute, the soot removal filling portion 21 is 180 mm wide, 100 mm high, 160 mm long, However, the size of the outlet opening of the filling part 21 for removing the soot is 160 mm wide and 80 mm high, the heater capacity of the filling heater 22 is 500 W, the set temperature is 580 ° C., and the soot removing filling is a commercially available zeolite.
