Soil remediation is a technical measure to restore the normal function of contaminated soil. In the soil remediation industry, there are more than one hundred soil remediation technologies. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out contaminated soil treatment and restoration plans, thus forming a new soil restoration industry.
Multifunctional soil rehabilitation rotary kiln mainly includes preheater, multifunctional soil rehabilitation rotary kiln, high-temperature fan tertiary air pipe at the end of kiln, multifunctional soil rehabilitation rotary kiln burner, grate cooler, kiln head bag dust collector, screw conveyor and trough conveyor. Exhaust emission national on-line monitoring, dust removal device fully meet the national emission standards.
Safe operating rules for multifunctional soil restoration rotary Kiln:
1. The excavated contaminated soil is pretreated in a closed environment (to remove bricks, cement blocks and other large particles that affect the working conditions of industrial kilns); To detect the contaminated soil, determine the composition of the contaminated soil and the content of pollutants, calculate the added amount of contaminated soil.
2. The contaminated soil is transferred to the feeding hopper by a special transport truck. In order to avoid secondary pollution caused by dust during unloading, the unloading area is sealed; The measured contaminated soil enters the feeding point through the pipe through the elevator and is sent to the high-temperature section of the smoke chamber at the end of the kiln for disposal; Pollutant concentration in flue gas discharge outlet of multifunctional soil repair rotary kiln and pollutant content in cement clinker should be monitored regularly.
