AI Technical Summary

Technical Problem

In traditional soil thermal desorption remediation equipment, heat loss occurs during the heat exchange process of flue gas, resulting in energy waste and high energy consumption.

Method used

Design a waste heat utilization device for soil thermal desorption remediation equipment, including a rotary kiln, a heat exchange box, a purification component, and a packing component. By setting multiple sets of coils and packing components in the heat exchange box, the packing component fills the gaps between the coils with packing material with high adsorption performance to adsorb high-temperature dust in the flue gas, maintain the coil temperature stable, and the old packing material is squeezed and replaced by a material handling mechanism to reduce the dispersion of flue gas dust.

Benefits of technology

This effectively reduces heat loss during the flue gas heat exchange process, improves waste heat utilization efficiency, reduces overall energy consumption, and ensures the stability and efficiency of equipment operation.

Abstract

This application discloses a waste heat utilization device for a soil thermal desorption remediation equipment, belonging to the field of energy recovery and utilization technology. It mainly includes a rotary kiln with an exhaust port on one side, a heat exchange box with an air inlet, multiple sets of coils installed inside the heat exchange box with gaps between them, an exhaust port on the other side of the heat exchange box, a purification component, and a packing assembly located on one side of the heat exchange box. The packing assembly includes a bridging box, which contains a feeding section and a pushing section. The feeding section is suitable for transferring the packing material to the pushing section. A material removal mechanism is located on the side of the heat exchange box away from the packing assembly, and is suitable for transferring the old packing material out of the heat exchange box. This waste heat utilization device for a soil thermal desorption remediation equipment, through the material removal mechanism, allows for convenient and quick replacement of old packing material with decreased adsorption performance. During the replacement process, the old packing material is compressed to reduce its volume and dust dispersion.
