Description

Technical Field

[0001] The utility model relates to the technical field of gas phase extraction, in particular to a gas phase extraction device for treating soil organic pollution. Background Art

[0002] Gas phase extraction technology is a method for extracting and separating target compounds from complex soils. It is usually used for in-situ remediation of volatile organic pollution in soils and to deal with pollution problems in formation media in the aeration zone. The basic principle is to use a vacuum pump to extract and generate negative pressure. When air flows through the contaminated area, it desorbs and entrains volatile and semi-volatile organic pollutants in the soil voids, which are carried away by the airflow and collected in extraction wells for final treatment to achieve the purpose of purifying the soil in the aeration zone.

[0003] The applicant searched the existing gas phase extraction devices and found that the existing soil gas phase extraction generally discharges the organic gas extracted from the soil directly into the atmosphere through the tail gas emission device, which causes air pollution while repairing the soil. In addition, the extracted gas contains liquid organic matter that cannot be discharged cleanly, which is likely to cause secondary pollution. The soil gas phase extraction remediation device disclosed in Chinese patent number CN216297496U includes a box body carried on a transport vehicle, an air pump connected to the outside is installed in the box body, and an air filter, a first blower, an absorption tower and an air-water separator are connected in sequence at the output end of the air pump, wherein an adsorption mechanism is connected to the right side of the air-water separator through an air pipe, an induced draft pump is fixedly installed at the output end of the adsorption mechanism, an exhaust pipe is arranged at the tail end of the induced draft pump, a detection unit is arranged on the exhaust pipe, a second blower connected to the absorption tower is arranged between the detection unit and the input end of the exhaust pipe, a degradation culture tank is connected at the bottom of the air-water separator, and the input end of the degradation culture tank is connected to the bottom of the absorption tower. It can directly carry out soil remediation on site and recycle organic pollution as soil nutrients, which is beneficial to reducing the pollution of the exhaust gas to the atmosphere and has better environmental protection.

[0004] However, the applicant found that when using gas phase extraction to treat soil contaminated organic matter, volatile and semi-volatile organic pollutants in the soil voids were removed, but other pollutants still existed in the soil, which could easily cause secondary pollution and had a poor remediation effect.
