Manufacturing method of sialon ceramic oil gas combustion tail gas treatment device

The invention discloses a manufacturing method of a sialon ceramic oil gas combustion tail gas treatment device. According to the invention, fly ash is adopted as a raw material; an element molar ratio is adjusted so that O:Si:Al=1:1:1; sintering is carried out, such that sialon ceramic powder is obtained; a proper amount of tung oil is added for mixing; the mixture is processed by using a cold isostatic press, such that sialon ceramic blanks are obtained; sintering molding is carried out; and the obtained sialon ceramic parts are combined according to different demands and different sizes, such that the sialon ceramic oil gas combustion tail gas treatment device is obtained. The device has the characteristics of high thermal conductivity, good wear resistance, good corrosion resistance, high strength, low cost, capability of performing heat exchange over large temperature difference span, and the like. The device is suitable for heat energy equipment with oil and gas as energy sources, such as industrial kilns, smelting furnaces and power plants, and civil-use boilers, air conditioners, internal combustion engines, fishing boats, gas water heaters and the like. The device can also be used in vehicle exhaust tail gas treatment. The device has a wide application range.
