Quartz Spherical Umbrella Bottle for Solar Acid Condensing/Collection/Recovery

The Quartz Spherical Umbrella Bottle, more technically referred to as a quartz umbrella condenser, is a highly specialized component critical to the solar cell manufacturing industry. Its primary function is the management and acid collection from corrosive process gases, specifically within Low-Pressure Chemical Vapor Deposition (LPCVD) diffusion furnaces. This is where phosphorus oxychloride (POCl₃) is used as a precursor to create the N-type junction on silicon wafers.

This complex chemical process generates hot, aggressive byproduct gases, primarily phosphorus pentoxide, which readily forms metaphosphoric acid in the presence of moisture. The quartz umbrella condenser solar system is designed to handle this exact challenge. Its operation begins with acid condensing. The hot gaseous effluent enters the condenser’s inlet, which is submerged within a cooled water jacket. The sophisticated spherical and umbrella-like design of the internal quartz structure is not arbitrary; it maximizes the surface area for heat exchange. As the gases flow over this cooled, sphericalsurface, they rapidly lose heat.

This cooling causes the gaseous acidic compounds to undergo a phase change, condensing into liquid droplets that adhere to the inner walls of the vessel. Gravity then takes over, pulling the collected liquid acid down into a dedicated chamber at the base of the bottle. This process of acid recovery is vital for two reasons. Firstly, it protects the downstream vacuum pump and exhaust system from highly corrosive damage, ensuring operational integrity and safety. Secondly, it allows for the safe containment and disposal of hazardous waste, preventing environmental release.

Constructed from high-purity fused quartz, the vessel offers exceptional resistance to thermal shock and corrosion from acids, ensuring long-term durability and performance in this demanding application. In summary, the Quartz Spherical Umbrella Bottle is an indispensable component for effective acid collection, enabling efficient and safe solar cell production.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.
