Abstract

The invention discloses a method for producing a high-titanium fly ash continuous fiber by using a high doped content fly ash. The method is as follows: taking 80-85% of fly ash, 10-15% of nano-titanium oxide, 2-3% of magnesium oxide, 3-5% of potassium oxide and 2-5% of an additive, mixing the above materials and then transporting the mixture into a flame pool kiln or electric melting kiln througha feeder, performing melting at 1550-1680 DEG C for 2.5-3.5 h, flowing into a leaky plate through a material passage, performing wire-drawing at 1300-1350 DEG C through wire-drawing equipment to obtain the high-titanium fly ash continuous fiber. The fiber can be used as a fire-proof and moisture-proof material, the waste fly ash can be effectively utilized, and the purpose of resource recycling is achieved.

Description

technical field [0001] The invention relates to the field of fly ash fiber manufacturing, in particular to a high-titanium fly ash continuous fiber and a preparation method thereof. Background technique [0002] Fly ash, commonly known as fly ash, is the waste of thermal power plants, that is, the dust brought out by the flue gas and collected by the dust collector after the pulverized coal is burned at 1500~1700 °C. According to statistics, every 1 ton of coal burned can produce 250~300kg of fly ash and 20~30kg of slag. [0003] In recent years, with the rapid development of the power industry, the discharge of fly ash in power plants has been increasing. Fly ash not only occupies a large amount of arable land and consumes a lot of water for washing ash, but also the secondary ash of fly ash causes serious harm to the ecological environment. In recent years, with the intensification of the contradiction between international energy supply and demand and the higher and hig...
