Technical field

The utility model relates to escaping gas process field, specifically relates to a kind of escaping gas treatment system.

Background technology

The escaping gas that industry and life activity produce is one of source of contaminated environment.Some is known, some is unknown, PM2.5 fine dust refers to that aerodynamic diameter is less than the particulate pollutant of 2.5 μ m, it is the key factor that causes breathing problem to propagate, these particles are suspended in not sedimentation in air for a long time, and easily carrying bacterium and virus, its 80% particle can enter in the alveolar of human body, is the one of the main reasons that causes PUD D.

For example, the harmful substance of the escaping gas that the metal of field of industrial production, plastic shaping process produce, test data shows, the escaping gas producing when plastic shaping and secondary operations and PM2.5 are 1%; Make a general survey of national plastic material total amount consumed, therefore known China will produce few hundred thousand tonnes of escaping gas and PM2.5 every year.In sphere of life, when huge numbers of families and restaurant's culinary art test data show that oil temperature rises to 155 DEG C-190 DEG C, the escaping gas and the PM2.5 that produce are 1.5%, the China on the tip of the tongue, and the edible oil total amount consumed year of making a general survey of whole nation processing produces few hundred thousand tonnes of escaping gas and PM2.5.
