摘要:
在横截面为200 mm×200 mm、高1 200 mm的方形截面冷态流化床反应器中,对4种异型模拟固体废弃物颗粒在不同床料辅助流化下的分布特性进行了试验研究.结果表明,床料密度对床层内颗粒混合的影响较大,床料密度的增大使固废颗粒的浮升趋势显著增强,单种固废颗粒在床层内的分布特性取决于床料密度与此种颗粒密度的比值ρb/ρp,且对4种固废颗粒考察后发现,当ρb/ρp≈2.4时,床层混合最为理想.床料粒径的增大同样增强了固废颗粒的浮升趋势,但提升幅度相对较小.床料体积分数增大有利于床层内颗粒的稳态混合,为保证固废流化床内良好的流化混合质量,床料体积分数应大于80%.
Abstract:
The mixing and segregation behavior of four kinds of irregular municipal solid waste(MSW)materials(wood, plastic, corn, building rubble)were experimentally investigated in a solid waste fluidized bed with a cross section of 200 mm×200 mm and a height of 1 200 mm. The results show that the bed materials density has a conspicuous effect on the mixing performance. Floating tendency of the simulating MSW materials is significantly enhanced with heavier bed materials. The distribution of a certain simulating MSW material depends on the density ratio of the bed material to the MSW material. Ideal uniformity of mixing is found when ρb/ρp approaches about 2.4. The sizes of bed materials have relatively smaller effects, though increasing the sizes of the bed materials also promotes the floating tendency of the simulated MSW materials. Besides, an adequate volume proportion of the bed materials is essential to fluidize the MSW and create a favorable environment for their mixing. In the present case, to achieve a good mixing the volume proportion should be over 80%. The distribution of MSW materials is found to be more uniform with the increase of the volume proportion.
