Device for collecting and disposing fugitive-emission volatile/semi-volatile gas in contaminated site

Abstract

The invention discloses a device for collecting and disposing fugitive-emission volatile / semi-volatile gas in a contaminated site. The device comprises support brackets, a cover material, gas collection and delivering pipelines, a tail gas processing system, an induced draft fan, an emission chimney and an automatic control system, wherein the support brackets are used for supporting the cover material; the gas collection and delivering pipelines comprise gas collection pipelines and gas delivering pipelines, the gas collection pipelines are arranged in the support brackets, and each gas collection pipeline is connected to each gas delivering pipeline through a soft connector; the gas delivering pipelines, the tail gas processing system, the induced draft fan and the emission chimney are connected in sequence, and the automatic control system can ensure the normal operation of the device through controlling the induced draft fan and the tail gas processing system. According to the device, the fugitive-emission volatile / semi-volatile gas on the surface of the contaminated site can enter the tail gas processing system through the gas collection and delivery pipelines to be processed, and then is emitted after the processed gas meets standards, so that the problem of collection and disposal of the fugitive-emission and volatilized volatile / semi-volatile gas in the reparation and construction process in the contaminated site is solved.

Description

technical field [0001] The invention relates to the field of contaminated site restoration, in particular to a collection and disposal device for unorganized emission of volatile / semi-volatile gases from polluted sites. Background technique [0002] With the acceleration of my country's urbanization process and the implementation of the strategy of "retreating from two to three" in the transformation of urban layout, almost all large and medium-sized cities in the country are facing the pressure of heavy polluting enterprises such as chemical industry, metallurgy, petrochemical, pharmaceutical, and waste material recycling and processing. Remediation of contaminated sites left over after batch shutdowns and relocations. [0003] The process of remediation of pesticide and chemical polluted sites involves fugitive emissions of volatile / semi-volatile gases, which has a serious impact on the lives and health of surrounding people, and also causes great inconvenience to the remed...
