A negative pressure airtight greenhouse applied to the repair of sites with irritating odor and its construction method and repair method

Abstract

The invention relates to a negative-pressure airtight greenhouse applied to repair of a place with pungent smells and a building method thereof, and a repair method. According to the negative-pressureairtight greenhouse applied to repair of the place with the pungent smells and the building method of the negative-pressure airtight greenhouse, the negative-pressure airtight greenhouse comprises anairbag greenhouse body, a vehicle corridor arranged on one side of the airbag greenhouse body, a feeding door arranged on the side of the airbag greenhouse body and located between the airbag greenhouse body and the vehicle corridor, a vehicle entrance and exit door which is arranged on the outer side of the vehicle corridor and corresponds to the feeding door, a tail gas treatment system arranged on the other side of the airbag greenhouse body and a gas return pipeline with one end connected to the tail gas treatment system. The negative-pressure airtight greenhouse is large in span, large in height, easy to mount and simple in mounting and demounting, off-site processing is achieved, and sound isolation and noise reduction are achieved. The building method is simple and convenient. Therepair method is environment-friendly and fast, and no secondary contamination is generated.

Description

technical field [0001] The invention relates to the technical field of contaminated soil remediation equipment, in particular to a negative-pressure airtight greenhouse applied to the remediation of sites with pungent odors and its construction method and repair method. Background technique [0002] Soil pollution can be divided into heavy metal pollution, organic pollution, biological pollution and radioactive pollution. A large number of industrial sites and agricultural lands in the country are polluted, seriously endangering human health, and need to be repaired and treated in time. At present, the main remediation technologies for polluted sites mainly include restoration workshops, excavation greenhouses, and temporary storage workshops. Due to the demand for working space in workshops during the construction of restoration equipment, the restoration workshops, excavation greenhouses, and temporary storage workshops are generally It must not be less than 12 meters, ot...

AI Technical Summary

Problems solved by technology

The forms of the above main supporting facilities can basically meet the construction needs of all polluted sites at the present stage, but the workshops of forms 1 and 2 have long construction period, complicated installation and disassembly, high turnover cost, and many welding and high-altitude operations. Increased project management costs and security risks

Although the air-bearing structure has the advantages of simple structure and short construction period, due to the positive pressure environment and the structural nature, the maximum height cannot exceed 10 meters, which greatly affects the construction efficiency and applicability
