| Abstract: |
| The dust in the soybean pretreatment workshop is divided into dry dust and moist dust, which is easy to cause equipment failure and workshop pollution. Under confined space and conditions, the dust can produce smoldering, fire or even explosion, which brings hidden dangers to safe production. In view of these problems, according to the characteristics of soybean pretreatment process and equipment, dust removal ventilation network and process ventilation network were designed. The dust-removing ventilation network and process ventilation network in soybean pretreatment workshop were introduced. In order to reduce the emission of dusty gas, the dust-removing ventilation network adopted the design of circulating air.The fire-proof treatment should be carried out at the dust collection place of chut, elbow and pipe links where smoldering and fire might occur, and the explosion-proof and explosion-supression measures should be taken for the silos where dust explosion might appear. The actual measurement of the dust-containing gas emissions of the 4 000 t/d soybean crushing plant showed that the ventilation network of the pretreatment workshop was stable, and the safe and clean production was achieved. |
