The invention provides a soil
thermal desorption rotary furnace testing
system and a testing method thereof. The testing
system comprises a carrier gas device, a rotary
thermal desorption testing device, and a
tail gas treatment device, wherein the carrier gas device comprises a
nitrogen bottle, a pressure reducing valve and an air inlet
erosion-resistant air guide hose; the rotary
thermal desorption testing device comprises a
pipe type
rotary furnace, an air inlet air pressure valve, a flow meter and an air outlet air pressure valve; and the
tail gas treatment device comprises an air outlet
erosion-resistant air guide hose, a condenser, a gas washing
bottle and an
active carbon adsorbing device. The testing
system and the testing method can be used for effectively and rapidly testing a contaminated soil thermal
desorption condition, and can obtain important technique design parameters such as a
nitrogen ventilation pressure, a heating rate, a rotating speed of a furnace tube, retaining time and
desorption efficiency before a soil thermal
desorption technology is applied to actual
engineering, so that the scientific guidance and the
technical support are provided for the actual application of the soil thermal desorption repairing technology. Thus, the soil thermal desorption
rotary furnace testing system provides the basis for the actual
engineering.
