Study On Ash-handling Technology Of Foundry Workshop

Carrying out research on dust treatment of foundry workshop, advancing energy conservation and emission reduction of foundry industry and building up enterprises energy-economical and environmentally-friendly is a significant and urgent task that placed in front of Chinese foundry industry. Through practical research to production workshop of foundry industry, this thesis analyses and studies the pollution situation, existing problems and factors affecting dust treatment in foundry workshop, and carries out an engineering analysis to the general situation of the project. Taken dust collecting process of casting equipments in a large foundry plant as actual research object, and targeting to provide a good work environment for personnel in foundry workshop, enhance productivity of the products manufactured and realize integrated automation of production process, a resolution plan for dust treatment of foundry workshop is put forward on the basis of utility and economy.With a view to existing problems in dust treatment process of foundry workshop, dust emission amount of all production equipments is calculated and analyzed, the pipeline layout is optimized reasonably, comparison is made for model selection of dust collector, filter material, blower and other accessory equipments, and an efficient dust collecting system is designed. This dust collecting system has been proved by actual operation that: the dust collecting efficiency of dust collector is > 99.8%, dust concentration at outlet ofthe dust collector is <50mg/m3, and ringelmann blackness is 1 degree, which attained design requirements. This research can offer reference for dust processing technology design and operation of similar foundry workshops.
