Abstract
A heat pipe-enhanced heat accumulation type indirect thermal desorption-based soil remediation device and method. On the one hand, by using thermal desorption gas generated by soil through heating and volatilizing as a heat transfer medium and by a circular heating manner, hot air efficiently transfers heat to the soil by contact, the treatment capacity of equipment is high. Moreover, high-temperature flue gas is kept from direct contact with the soil, so the high-temperature flue gas is prevented from being mixed with gaseous organic contaminants. Therefore, only a small amount of excess gas needs to be purified, so the equipment scale is small. On the other hand, by equipping a reactor with heat pipes and a ceramic heat accumulator, a second soil heating manner is provided, so that the heat transfer capacity per unit volume of the reactor is increased, and the treatment efficiency is significantly improved under the same scale.
