Title:
SITE HEAVY METAL CONTAMINATED SOIL TREATMENT EQUIPMENT AND TREATMENT METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/192241
Kind Code:
A1
Abstract:
Site heavy metal contaminated soil treatment equipment, comprising a sampling system, a molding system, a heat processing system and a tail gas processing system which are disposed in sequence; the sampling system includes a bucket elevator and a planetary stirring device which are connected in sequence and are both disposed on a mobile platform of the sampling system; the molding system includes a vacuum extruder (3-1), a first conveyor belt (3-2), a cutter's station (3-3), a first mobile platform (3-4) and a second mobile platform (3-5) which are disposed in sequence; the vacuum extruder (3-1) is located on the first mobile platform (3-4), the first conveyor belt (3-2) and the cutter's station (3-3) are located on the second mobile platform (3-5), and the discharge outlet of the planetary stirring device is connected to the feed inlet of the vacuum extruder (3-1). The heat processing system comprises a drying furnace (4-3), a microwave oven (4-4), a cooling room (4-5) and a kiln car track (4-2) which are all disposed on a mobile platform (4-6) of the heat processing system; the tail gas processing system comprises an oxy-fuel combustion apparatus (5-1) and a spray tower (5-2) which are both disposed on a mobile platform (5-3) of the tail gas processing system. The treatment method using the site heavy metal contaminated soil treatment equipment comprises the following steps: moving, by means of the mobile platform of the sampling system, the first mobile platform (3-4), the second mobile platform (3-5), the mobile platform (4-6) of the heat processing system and the mobile platform (5-3) of the tail gas processing system respectively, the sampling system, the molding system, the heat processing system and the tail gas processing system to the site where a heavy metal contaminated soil treatment is required, then the heavy metal contaminated soil and the coal gangue are added into the sampling system and conveyed to the molding system for compression molding, blanking and setting; the blanks are sent to the heat processing system by the kiln car (4-1) for burning, and the generated exhaust gas is introduced into the tail gas processing system and then discharged when the standard is reached.
