Abstract

See full text

A hot air circulation type indirect thermal desorption-based soil remediation system and method, belonging to the technical field of soil remediation. The system includes a thermal desorption reactor, a dust remover, a hot air circulating fan, a hot air heater, an air preheater, a combustion fan and a combustion device. By using thermal desorption gas generated by soil being heated and volatilized as a heat transfer medium and by a circular heating manner, hot air efficiently transfers heat to the soil by contact, and the high-temperature fume is kept from direct contact with the soil, so the system has the advantages of high treatment capacity, small equipment scale and the like.
