Collection device for volatile organic compounds from crushing and thermal pretreatment of electronic waste

The invention relates to a collection device for volatile organic compounds from the crushing and the thermal pretreatment of electronic waste. The collection device comprises an air inlet pipe, an air guide pipe, and an allochroic silica gel adsorption tank, an active carbon adsorption tank, a front end adsorption pipe, a pollutant releasing cabin, a snakelike cooling pipe, a rear end adsorption pipe and a centrifugal air pump which are sequentially connected with one another through the air guide pipe, wherein the snakelike cooling pipe is arranged in a cooling water trough, the pollutant releasing cabin is arranged on a heating plate, and the lower part of the heating plate is provided with a temperature controller. A triple quadrupole gas chromatograph-mass spectrometer is used for detection, so that the collection device has characteristics of low cost, high efficiency, simple structure, no pollution and the like, the volatile organic compounds can be collected from the mechanical crushing and thermal pr
