Abstract: The present invention provides devices or systems and a method for remediating a soil comprising contaminants, comprising the steps of:—introducing in said soil at least one perforated column for contaminant extraction from a contaminated region of said soil; in close proximity of said at least one perforated column introducing at least one non-perforated column for providing heat to said contaminated region of said soil; providing heat to said at least one non-perforated column; extracting said contaminant vapor containing said soil contaminants out of said contaminated region of said soil into said at least one perforated column; removing said contaminant vapor from said at least one perforated column, thereby providing remediated soil; wherein said at least one perforated column and said at least one non-perforated column are connectable to at least one surface-located device comprising a combustion, a heating and control unit for heating and thereby cleaning said soil.

Abstract: An improved heat evaporation soil remediation system has feeder bin, rotary dryer and baghouse elements integrated as a single compact unit onto a readily transportable trailer platform. Contaminated soil is fed by means of an auger and slinger belt into an oil burner fired rotary drum for heating by flight induced veiling action and evaporation of volatile contaminants from the soil. Dust-laden exhaust air is cleaned by air expansion and bag filters in a baghouse located over and straddling the dryer. The bags are maintained in position by springs to prevent excessive movement during travel.
