Abstract

The invention discloses a pipeline type high-pressure spraying elution device for contaminated soil remediation, and relates to the technical field of soil remediation equipment. The elution device comprises a slurry tank, a slurry pump, a high-pressure spraying elutriator and a high-pressure power unit; according to the invention, the slurry in the slurry tank is pumped into the high-pressure spraying elution device through the slurry pump; the cleaning liquid is conveyed into each high-pressure pipe and each high-pressure nozzle in a high-pressure state through the high-pressure power unit;the cleaning liquid is then sprayed out at a high pressure of 20-80 Mpa through a high-pressure nozzle; the cleaning liquid passes through a converging section formed by concentrating high-pressure jet flow, and the total hedging force in the section can reach 30-150Mpa, so that the mud is fully mixed, cut and collided, pollutants are promoted to be stripped from soil particles, and the intensified elution of the polluted soil is realized. According to the invention, effective separation of pollutants and soil fine particles can be promoted, the process bottleneck of an existing soil leachingtechnology can be broken through, the environmental safety of a remediation terminal can be improved, and the comprehensive remediation cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of soil remediation equipment, in particular to a pipeline-type high-pressure spray eluting device and an eluting method for remediating contaminated soil. Background technique [0002] Soil leaching technology is one of the widely used soil remediation methods at home and abroad. It is a method to remove soil pollutants by using the fluidity of the eluent and the reaction characteristics of the eluent itself and pollutants. Or desorption to realize the transfer process of pollutants from solid phase to liquid phase, which can treat inorganic or organic polluted soil at the same time, and is also one of the few remediation methods that can permanently deal with heavy metal pollution. [0003] The patent No. CN109078974A in the prior art discloses a clean water high-pressure leaching soil remediation system, which includes a soil supply device for supplying the object soil; a leaching water supply device for ...
