The Design And Creation Of A Factory Whose Annual Output Is 10 Million Dialyzers

This article is around the annual output of 10 million hemodialysis with dialyser factory created to design, including the dialyzer project feasibility report and the plant design, feasibility report by industry status, market demand, technology management and financial aspects has carried on the detailed analysis, then explain the feasibility of the project;Factory, on the other hand, created from site selection, equipment purchase, workshop design, technology route and so on has carried on the detailed design.In review section, I at first analyzes the working principle of dialyzer, introduced the physics principle of dialysis membrane, and then respectively to the study of dialysis membrane at home and abroad were summarized, and finally forecasts possible development direction of the dialysis membrane.Then on the project feasibility study, in this part, first of all, the background and necessity of the project are analyzed, and then respectively in the policy, market, technology, management and financial aspects of the feasibility analysis, finally the dialyzer market are analyzed in general.Then the dialysis membrane(polysulfone membrane) of modification, the phase catalysis with 10-channel DMAc solvent for the preparation of polysulfone ultrafiltration membrane, add additive of a low molecular weight of PEG, improve the structure of the membrane morphology and improve the performance of the membrane, through discussion and analysis can know, with the increase of PEG content, polysulfone membrane permeability increased, the porosity will increase, while the closure rate is on the decline;On the other hand to the same kind of additive of different molecular weight of polysulfone membrane, also has effect on the performance of the overall trend is the molecular weight, the greater the permeability is, the better.The next,I analyse the factory’s creation comprehensively. Main aspects: site selection, formulation of raw materials and technology, factory building general administration, the environment and the "three wastes" treatment, production safety, the company’s organization and labor’s capacity, the financial evaluation and calculation, etc.In the design part, first I have carried on the technological designation, mainly from the purpose and function of product design for product parts and raw material types, determine the PP and PVC as main ingredient, then through the material balance of the materials they need to calculate the year overall quality, and on this basis, according to the production efficiency of injection molding machine to determine the number of the injection molding machine. Then design the equipment to finalize the design and quantity, through the calculation of the material can determine the amount and type of equipment. When the equipment was determined, can to the factory area have a ballpark estimate. Finally has carried on the workshop design, from the first planned production and equipment number calculation workshop need area, then fanishied the detailed designation according to the requirements of process route and cleanation standart of the workshop.
