Have equally distributed aperture on the described aeration tube.
Described suction branch is a flexible pipe, has equally distributed aperture on the flexible pipe.
The bottom in described reparation pond is equipped with catch net.
Owing to adopted above technical scheme; The contaminated soil heterotopic aeration treatment system of the utility model adopts and repairs the pond, has the gas injection device of preheating, the version of vapor extraction device; Can be in batches contaminated soil be transported to and carries out the strange land in the reparation pond that the bottom is equipped with aeration tube and handle, have stronger flexibility.Because this system has adopted the gas injection heater, can heat injecting gas, the aeration treatment effeciency is high, and the processing cycle is short.Be provided with waterproof cloth owing to repair the top, pond, can isolate volatility dusty gas and air.Water seal arrangement is connected waterproof cloth with the limit wall seamless of repairing the pond, make the air of repairing pond internal contamination soil and repairing outside the pond isolated, prevents that toxic gas from leaking.Be located at temperature monitor and the pressure detecting instrument of repairing the top, pond, can monitor the temperature and pressure of repairing in the pond in real time, regulate control air extractor and gas injection device according to this, can significantly reduce the vent gas treatment amount, save processing cost.Be the antiseepage body with pool wall at the bottom of the pond in reparation pond, can solve the leakage and the diffusion problem of the volatile contaminant that in processing procedure, occurs, effectively avoid secondary pollution contaminated soil.Because aeration tube is arranged in the aeration tube groove, makes the contaminated soil Transport Machinery can freely get into the arbitrary region of repairing in the pond and operate.The catch net of aeration tube groove top can effectively protect the injecting hole of aeration tube not stop up.
The contaminated soil heterotopic aeration treatment system of the utility model is rationally distributed, simple in structure, small investment; Efficient is high, and is effective, and the processing cycle is short; Can be flexible and efficient, safely and reliably contaminated soil is carried out dystopy and handles; Avoid secondary pollution, can also significantly reduce the contaminated soil disposal cost, reduce cost.
