Embodiment Construction

[0015] The present invention is described in further detail below in conjunction with accompanying drawing:

[0016] see Attachment

[0017] A device for solar energy ectopic restoration of volatile organic compound-contaminated soil, which is composed of a solar steam supply system, a soil remediation bin, a water circulation system and connecting pipes. The solar steam supply system is composed of a group of solar receiving devices, and each solar receiving device is composed of The support 1, the trough-shaped concentrating shell 2, the heat-absorbing tube 3 and the bracket 4 are composed. The two ends of the trough-shaped concentrating shell 2 are hinged on the support 1, and the direction of the shell can be freely adjusted according to the angle of sunlight. , can also adopt the automatic tracking design, the long trough structure of the trough-shaped concentrating shell 2 realizes the solar area heating, the support 4 is symmetrically fixed on the outer edges of the two...

Abstract

The invention discloses a device for the solar ex-situ remediation of volatile organic pollution soil, comprising a solar steam supply system, a soil remediation bin, a water circulation system and a connecting pipeline. The device acquires heat through light condensation by utilizing solar radiation and supplies hot steam used for soil remediation by heating water inside a heat-absorbing tube, and the water circulation system continuously supplies the needed water. The device for the solar ex-situ remediation of the volatile organic pollution soil integrates steam supply, soil processing andwater cyclic utilization into a whole, has the advantages of compact structure, convenience of operation and energy saving, can be applied to large-scale engineering, realizes the efficient and fast remediation of various volatile and semi-volatile organic pollution soils, and provides the technology and the equipment for the processing and the remediation of the organic pollution soil.

Description

technical field [0001] The invention discloses a device for ectopically repairing volatile organic compound polluted soil by solar energy, which belongs to the category of environmental restoration equipment. Background technique [0002] At present, my country's soil organic matter pollution is very serious, and organic compound pollution has surpassed heavy metal pollution and radioactive pollution and has jumped to the first place. The farmland polluted by various organic pollutants (pesticides, petroleum hydrocarbons and PAHs, etc.) in China has reached 3.6×10 7 hm 2 , most of the organic pollutants are carcinogenic, and the hazards to agricultural products and human health have begun to emerge. With the acceleration of industrialization and urbanization in our country, more and more soils are polluted by organic matter. Organic matter adsorbed in the soil or migrated to groundwater and the atmosphere will directly or indirectly pose a threat to human life. In recent y...
