High Corrosion-resistant Al₂O₃ Ceramic Atomizing Nozzle for Environmental Industry

High Corrosion-resistant Al₂O₃ Ceramic Atomizing Nozzle for Environmental Industry

Product Description

The ceramic nozzle body of this Ceramic Atomising Nozzle boasts a Mohs hardness of 9; the precision central micro-orifice maintains a constant diameter despite prolonged fluid erosion, ensuring long-term stability in atomization flow rates and droplet sizes. The alumina material is chemically inert, resistant to various corrosive acidic and alkaline atomizing agents, and capable of continuous operation at temperatures up to 900°C without cracking, even amidst the rapid thermal fluctuations typical of flue gas environments. The dense, smooth ceramic surface resists mineral scaling and minimizes the risk of orifice clogging. Furthermore, the material offers excellent electrical insulation and releases no metal ions, making it suitable not only for high-temperature flue gas quenching in incinerators and the atomization of corrosive chemicals but also for high-purity atomization and humidification in lithium-battery manufacturing and electronics cleanrooms. With a comprehensive performance profile characterized by high hardness, corrosion resistance, high-temperature tolerance, and precision atomization, alumina ceramic nozzles are rapidly replacing traditional metal nozzles across the power generation, environmental protection, chemical, and metallurgical industries. They represent not merely an upgrade to a single component, but a holistic improvement in the reliability, cost-effectiveness, and environmental sustainability of the entire process system.

Key Material Properties

High-purity alumina ceramics (Al₂O₃ ≥ 95%)

Atomization Mechanism and Structural Configuration

Alumina ceramic atomizing nozzles offer various atomization configurations tailored to specific operating conditions:

1. Spiral Tangential Atomization

liquid enters a spiral flow channel tangentially, forming a hollow or solid cone-shaped spray pattern under centrifugal force. The channel features a coreless, dead-zone-free design with excellent anti-clogging performance, making it suitable for atomizing slurries with high solids content.

2. Pressure Atomization

mechanical atomization is achieved using the liquid's own pressure as it passes through a precision-machined, constricted flow channel. This compact design produces uniform droplet sizes and is suitable for clean liquids and low-to-medium pressure applications.

3. Impingement Atomization

multiple liquid streams collide—either inside the nozzle or at the outlet—breaking apart into fine droplets. This method yields small droplet sizes with a narrow distribution, making it ideal for precision processes requiring ultra-fine atomization.

4. Modular Atomization Systems

ceramic nozzles of different structural types can be combined modularly to meet specific process requirements, enabling complex spray schemes such as zoned coverage and gradient atomization.

Product Advantages

1.Exceptionally Long Service Life

alumina ceramics possess extreme hardness; in environments involving slurry jets containing solid particles, their wear rate is merely one-tenth to one-fiftieth that of metal nozzles. Taking limestone-gypsum desulfurization as an example, ceramic nozzles can last 2 to 5 years, whereas alloy nozzles typically last only 3 to 6 months.

2.Stable Atomization Performance

ceramic materials are resistant to corrosion, oxidation, and thermal deformation. The dimensions of the flow channel remain precise and consistent over the long term, ensuring that the spray angle, flow rate, and droplet size remain stable and controllable throughout the product's entire lifecycle.

3.Superior Corrosion Resistance

they withstand attack by highly corrosive ions—such as Cl⁻, SO₄²⁻, and F⁻—found in desulfurization slurries, as well as chemical corrosion from denitrification media like aqueous ammonia and urea solutions, fundamentally eliminating the perforation issues associated with metal nozzles.

4.High Efficiency and Energy Savings

the smooth inner walls of the ceramic flow channel (Ra ≤ 0.4 μm) significantly reduce fluid resistance. This allows for higher flow rates or finer atomization at the same pressure, thereby lowering energy consumption for pumping.

5.Broad Media Compatibility

they are suitable for handling water, acidic and alkaline solutions, slurries, oils, and high-viscosity liquids, and are resistant to clogging caused by crystallization or coking of the medium.

Technical Specifications

Selection and Usage Guide

1.Selection Criteria

   medium analysis: determine the liquid composition, temperature, solids content (percentage), and corrosivity; select the appropriate purity grade of alumina material.

   process requirements: define the target droplet size, coverage area, flow rate, and system pressure.

   structural matching: choose spiral-type nozzles for high solids content, pressure-type for clean liquids, and impingement-type for ultra-fine atomization.

   installation conditions: verify piping connection standards, spatial layout, and vibration-proofing requirements.

2.Installation and Maintenance Recommendations

   handle with care: ceramics are brittle materials; avoid dropping or impacts from hard objects.

   uniform tightening:uUse a torque wrench for threaded connections to prevent cracking caused by uneven stress.

   regular cleaning: establish a cleaning schedule based on the medium's properties to prevent scale buildup in flow channels, which could impair atomization performance.

   spare parts management: maintain an adequate stock of spare parts for critical stations to ensure continuous production.
