Abstract Known as "black pollution" refers to old tires, as a global problem the recycling and processing technology has been consistently research around the world, how to effectively, security in dealing with a tricky old tires, has become a major problem of environmental protection。
Wet flue gas desulfurization process is a stable and reliable technology is relatively mature, comprehensive utilization of by-products, raw material resources more easily take the device efficiency and sulfur in addition to a relatively high efficiency of the method, after the relevant literature, this paper, in addition to sulfur system is limestone - gypsum system for mathematical modeling。 A relatively small volume of bag filter, the price has a great advantage, and the use of safety, handling a wide variety of dust particle size, design and calculation of the article after the relevant literature and Design Manual pyrolytic devices dust desulfurization system used by the constant device and select the device model based on the obtained parameters。 And the establishment of three-dimensional model of the baghouse hopper by Ansys software for finite element structural mechanics analysis。 Through system design and finite element analysis to the conclusion, increasing the thickness of the wall of the hopper bag filter can improve life and increase the height of the hopper dust can reduce the deformation of dust than to take two to take a group of high efficiency some increase the spray tower height allows the system to improve the efficiency of desulfurization。
