Zirconia is a kind of ceramic material with excellent physical and chemical properties, which is widely used in electronic, chemical, mechanical and other fields. High purity zirconia has broad application prospects. This article will introduce a key equipment--Zircon sand chlorination furnaceIt plays an important role in the production of high-purity zirconia.

1.Zircon sand chlorination furnaceThe working principle

The zircon sand chlorination furnace is an equipment that uses chlorination reaction to convert zirconium dioxide in zircon sand into zirconium tetrachloride. Its working principle is to chlorinate the treated zircon sand with the chlorinating agent at high temperature to generate zirconium tetrachloride gas. After condensation, separation and other steps, a high-purity zirconium tetrachloride product is obtained.

2.Zircon sand chlorination furnacestructure and characteristics

Furnace body: The furnace body is made of excellent high temperature resistant materials, and the design structure is firm, which can effectively resist the working environment of high temperature and high pressure.

Heating device: The heating device adopts advanced electric heating elements with uniform distribution, which can ensure uniform temperature in the furnace and improve the efficiency of chlorination reaction.

　
Condenser: The condenser adopts a heat exchanger, which can effectively recover the heat in the zirconium tetrachloride gas and reduce energy consumption.

Control system: The control system adopts automatic control, which can monitor the temperature, pressure and other parameters in the furnace in real time to ensure the stability and safety of the production process.

3.Zircon sand chlorination furnaceThe operation process

Pretreatment: cleaning, drying and other pretreatment of zircon sand to ensure that it meets the requirements of furnace.

Feeding: Add the pretreated zircon sand into the furnace and close the furnace door.

Heating: The heating device is activated to gradually increase the temperature in the furnace to a predetermined reaction temperature.

Condensation: The generated zirconium tetrachloride gas is condensed to separate the zirconium tetrachloride in a molten state.

Separation: The condensed zirconium tetrachloride gas is separated to obtain a high-purity zirconium tetrachloride product.

End: cleaning equipment, finishing four zirconium chloride products, complete a production process.

4.Zircon sand chlorination furnaceThe optimization strategy
