Soil cleaning system with cleaning the transfer pipes by high-pressure water

摘要

The present invention is a cleaning device for washing and sorting contaminated soil, a reaction tank for receiving a mixed fluid including contaminated soil and process water classified from the cleaning device to elute contaminants and agglomerate and precipitate the eluted contaminants, the reaction tank A four filtration tank that receives supernatant water from the water and circulates treated water to the cleaning device by filtering contaminants using the silt washed from the cleaning device, and a dehydrator that dehydrates and dehydrates the contaminants precipitated from the reaction tank. In the soil washing system comprising: a three-way valve consisting of one or more pairs at a specific location of a transfer pipe among the washing apparatus and having a connection portion formed on one side thereof; A circulation pipe portion having both ends fastened to the connection portion of the three-way valve and communicating with a transfer pipe portion between the three-way valves to form a circulation line under the control of the three-way valve; And a circulation induction device including an air injection line connected to the circulation pipe to circulate air at high pressure in the circulation line and an air injection pump for pumping air to the air injection line; It relates to a soil washing system capable of washing pipes.
