This paper expounds the design mechanism and principle of control device work environment for dust pollution control and prevention working condition, in waste money drilling processing. This paper also presents the technological process, the device structure design and work mechanism of the device and lays emphasis on the working principle, the classification and selection of the dust filter; presents the classification comparison and selection, the design and characteristic calculations of gas collecting dome; introduces the design, installing methods, main parameter calculations of the piping system, and the computations and selection of the motor and the fan device as well; presents the classification of bag type filter, the requirement and selection of filter bag, and the calculation of main parameters of dust filter. The design of the device not only increases the waste paper recovery efficiency in the process of disposing waste money and avoids dust pollution, but also contributes to the safety, security and the inspection of disposing procedure.
