restoration system of contamination soil and waste reclaiming soil

摘要

PURPOSE: A remediation system for contaminated soil and landfill site is provided, which is movably installed where remediation is necessary and remediate contaminated soil by separation, drying and sterilization at drying system of rotary kiln type. CONSTITUTION: The remediation system comprises a hopper(10), a screening system(20), a combustion system(40), a drying system(50) and a deodorizing system(60). Landfilled waste is fed to hopper(10) and conveyed to screening system(20) by a feed conveyor(11). At the screen system(20) that resembles a double trommel of inner and outer screens, soil and stone are separated from waste at outer trommel and iron matter is further separated at magnetic conveyor(15). The residual waste is fed to incineration system that consists of a No.1 incinerator(41), a No.2 incinerator(44) and a dust collector(46), the unburned gas burning at the No.2 incinerator(44). The waste separated from the screen system(20) is fed to drying system(50) which use waste heat of about 1100 deg.C of the incinerators(41,44) as heat source to be dried and sterilized and odorizing gas generated from the drying system is deodorized at deodorizing system(60).
