Design And Application Research Of LW-450N Closed Type Gas Seal Decanter Centrifuge

Four titanium chloride is an important raw material for the production of titanium material and electronic package. Due to adopt the process of molten salt chlorination, it bring to the fine dust purification chloride furnace outlet. It will produce four titanium chloride suspension containing about 7%,but the production can be recoveried with high value. Due to the presence of high concentration of four titanium chloride suspension and chlorine, chlorine and moisture in the air with hydrochloric acid gas. So it cause serious pollution to the environment. It is a serious problem in the production of titanium chloride four. In this paper, by selection of horizontal spiral unloading set centrifuge to separate four titanium chloride suspension. it is useful the special structure of gas seal airtight, solved the problem of four titanium chloride suspension in the solid-liquid separation in four titanium chloride leakage.In this paper, the separation material independently of the LW-450 gas seal type centrifuge process design with four titanium chloride suspension, the overall structural design and calculation and drawing the corresponding structural attachment strength of the assembly drawing and parts drawing.Through the design of the prototype trial application in field shows that the prototype can meet the production process of four titanium chloride. Equipment can automatically separate and it mud cake separated into recycling chloride furnace. After the separation of the liquid does not contain solid dust. In the processing capacity of 3 m3 each hour under the conditions of operation and centrifuge speed 1800r/min. What’s more fixed rate is about 0.2% with the separation of liquid, The nitrogen sealing effect is good at avoid gas leakage, it can effectively solve the problem about four titanium chloride slurry suspension four titanium chloride leak.By operated for more than two years, the plants can used to reduce the operating staff of 16 people to the separation section. reducing the labor intensity and improving the degree of automation, it is very important to eliminate environment of pollution and created good economic and social benefits.
