Research On The System Of Recovery And Disposal About Waste Household Appliance And Its Technical Process

Unbefitting disposal of the large number of waste household appliances will multiply consumptions of natural resources and aggravate natural environment. So, how to recovery and reuse the waste household appliance cause the people of the world more focuses and so many countries and organizations start a deep research in this field.The waste household appliance of china is larger than the others, but the scale of recovery and disposal is very lower and its technical and technology is straggling, and that contaminates the natural environment badly . To surprise, the large recycle factories are always short of waste household appliance resources. So we must build a efficient system of recovery and disposal about waste household appliance urgently. Considering our state practice, this paper analyses the system of recovery and disposal about waste household appliance in other countries and its successful experiences, and starts the research on the system of recovery and disposal about waste household appliance and its technical process. Here are several aspects of the study:(1) It introduces the signification of and recovery about waste household appliance and the situation in our country and the others , analyzing the problem in the research, and submits the necessity about the research about it.(2) We must energize the construction about the recycle network and the system in order to recycle it efficiently. This paper discusses every function unit of the system and gives some concrete measures about it.(3) The emphasis in the paper is. the technology about recovery and disposal of the waste household appliance. Firstly, it analyses the different policy of different kind of appliances to decide a proper disposal model. Then, gives the separate study in three phases to ascertain and plan its technical technology and process.(4) Dismantling is the hot spot in the research on the disposal about waste appliance, and it also is a key problem. Proper dismantling is the premise of efficient recycle. Obeyed by some principles and based on the assembling model of the appliance, the paper discusses three aspects issues: building AND/OR dismantling model, producing sequence of dismantling and giving some appraisals of it based on the economical indicator.(5) Crushing and classification is the vital technology in the waste appliance recycle, and it is the component of recycle technical decision-making. The paper analyses function of these key technologies, and settle on how to use and pick the proper equipment in the process.
