Embodiment 1
[0025] After the urban sludge with a moisture content of 80% to 90% is dehydrated through a plate filter press (1) to a moisture content of 50-60%, the dewatered sludge: coal powder: cement: fly ash: plant The mass ratio of fiber=68%: 14%: 6%: 10%: 2% is taken, and placed in storage bins (3), (4), (5), (6), (7) respectively; after that Transport it to the homogenization bin (8) for mixing, and then send it to the mixer (9) to mix evenly; then lift it to the extrusion pelletizer (11) through the elevator (10) to extrude the mixture to prepare granules Sludge pellets with a diameter of 10-20mm.
[0026] The sludge balls are sent to the drying kiln (13) through the transmission belt (12) and dried until the moisture content is 8-12%, and the drying temperature is 150-180°C; the dried sludge balls are then passed through the elevator (14 ) is transported to the pyrolysis dry distillation gasifier (15) for reaction.
[0027] The inside of the pyrolysis dry distillation gasifier (...
Embodiment 2
[0033] After the urban sludge with a moisture content of 80% to 90% is dehydrated through a filter press to a moisture content of 50-60%, the dewatered sludge: coal powder: cement: fly ash: plant fiber = 80% : The mass ratio of 9%:4%:6%:1% is taken.
[0034] The rest are operated according to Example 1 to obtain light and high-strength ceramsite and recycle combustible gas C m h n 、H 2 and CO, etc.; the waste heat when the ceramsite is cooled is used as the heat when the sludge pellets are dried in the kiln.
Embodiment 3
[0036] After the urban sludge with a moisture content of 80% to 90% is dehydrated through a filter press to a moisture content of 50-60%, the dewatered sludge: coal powder: cement: fly ash: plant fiber = 88% : The mass ratio of 6%:2%:3%:1% is taken.
[0037] The rest are operated according to Example 1 to obtain light and high-strength ceramsite and recycle combustible gas C m h n 、H 2and CO, etc.; the waste heat when the ceramsite is cooled is used as the heat when the sludge pellets are dried in the kiln.
