Fire disaster soil pollutant treatment device for electrical equipment of transformer substation

Abstract

The invention relates to a fire soil pollutant treatment device for electrical equipment of a transformer substation. The fire soil pollutant treatment device comprises a pretreatment mechanism, a feeding mechanism, a thermal desorption mechanism, an air preheater, a dust collection mechanism, a gas-phase pollutant conversion mechanism and a tail gas detection mechanism; the pretreatment mechanism is positioned in front of the feeding mechanism; the feeding mechanism is arranged in the thermal desorption mechanism in a sleeving manner; the air preheater is embedded in the thermal desorption mechanism; a discharge hole of the feeding mechanism just faces the tail end of the thermal desorption mechanism; the tail end of the thermal desorption mechanism, the dust collection mechanism and the gas-phase pollutant conversion mechanism are sequentially communicated with one another through a pipeline; the tail end of the pipeline at the outlet end of the gas-phase pollutant conversion mechanism is communicated with a four-way valve; and one way of the four-way valve is communicated with the tail gas detection mechanism through a pipeline, one way of the four-way valve is communicated with the atmosphere through a pipeline, and the last way of the four-way valve is communicated with a pipeline arranged between the dust collection mechanism and the gas-phase pollutant conversion mechanism through a pipeline.

Description

technical field [0001] The invention relates to a soil pollutant treatment device for substation electrical equipment fire, which belongs to the technical field of electric power and environmental protection. Background technique [0002] In recent years, substation fire accidents have occurred occasionally. Substations (especially urban substations) are generally deep in areas with high population density. Once a fire breaks out in a substation, in addition to causing economic losses, the decomposition products and residues after the fire will cause varying degrees of environmental pollution to the water, air, and soil around the substation, destroying the surrounding ecological environment, and seriously affecting people's health and safety. . [0003] The flue gas mixture produced by combustion after a fire in a substation mainly includes CO, CO produced by the combustion of grease volatiles, grease and cable insulation. 2 Carcinogens such as polycyclic aromatic hydroc...
