It appears you are looking for information on a customized industrial high-pressure fan (blower) specifically designed for a Soda Ash project, likely used as a Lime Blower.
This is a very specific piece of industrial equipment. Below is a breakdown of what this application requires, the technical specifications you should look for, and how to customize it for a Soda Ash production line.
The Application: Lime Blower in Soda Ash Production
In the Solvay process (the main method for producing synthetic soda ash), quicklime (CaO) is a critical input. A "Lime Blower" (a high-pressure fan) is used to pneumatically convey powdered quicklime from storage silos to the slaking tanks or directly into the process.
Why a Customized High-Pressure Fan is needed here:
- Abrasive Material: Quicklime is highly abrasive.
- Hygroscopic & Reactive: Lime reacts with moisture and CO2 in the air. The fan must handle dry, dense-phase conveying.
- High Pressure: Dense phase conveying requires high static pressure (often 0.5 to 1.5 bar / 50-150 kPa).
- Continuous Duty: The process runs 24/7.
Key Technical Specifications for Customization
When ordering a fan for this project, you must specify the following parameters to the manufacturer.
| Parameter | Typical Requirement for Lime Blower | Why it matters |
|---|---|---|
| Type | Centrifugal Fan (Radial blade or Paddle wheel) | Radial bladed fans handle dust and high pressure best. |
| Airflow (m³/hr or CFM) | Variable (Depends on 50-150 TPH lime transport) | Too high = pipe erosion; Too low = line blockage. |
| Static Pressure | Very High (8000 - 15000 mmWG / 80 - 150 kPa) | Must overcome friction of dense lime in a long pipeline. |
| Temperature | Ambient to 80°C (Inlet temp). Material temp for gas temp rating. | Gaskets and bearing cooling must be specified. |
| Impeller Material | Wear-Resistant Steel (e.g., Hardox, Abrasion-resistant steel, or Stainless Steel 304/316 with hard-facing). | Lime erodes mild steel quickly. |
| Casing Lining | Replaceable Wear Liners (Ceramic tiles, hard-chrome plating, or rubber lining). | Extends fan life by 3x-5x vs. unlined casing. |
| Seals | Labyrinth Seals / Air Purge Seals | Prevents lime dust from entering bearings, which would cause failure. |
| Drive | Direct drive (preferred) or V-belt with VFD (Variable Frequency Drive) | VFD allows precise control of conveying velocity to prevent pipe wear. |
H2: Customization Options for your Project
Here is what you should ask your fan manufacturer for:
Impeller Design (The core component)
- Closed Backward Curved: More efficient but less tolerant to dust.
- Radial (Paddle Wheel): Lower efficiency, but best for abrasive, sticky materials like lime. Highly recommended.
- Coating: Request a tungsten carbide spray or hard chrome on the leading edges of the blades.
Casing Design
- Volute Casing: Standard.
- Material: Minimum AR400 (Abrasion Resistant) steel.
- Liners: Ceramic lining (Alumina 92% or 95%) in the cut-off area (volute tongue) is a game-changer for longevity.
Bearing & Shaft Protection
- Split Pillow Block Bearings: Easy to replace.
- Lube system: Centralized greasing or oil mist.
- Shaft Cooling: If the lime is hot, a fan wheel on the shaft or a water-cooled bearing housing may be needed.
Outlet/Inlet Configuration
- Inlet: Bell mouth with anti-abrasion ring.
- Outlet: Should be flanged. Customize the orientation (e.g., Up-blast, Down-blast, Horizontal-Left/Right) to fit your piping layout.
Accessories
- Inlet Box Damper: For manual airflow adjustment during commissioning.
- Silencer: High-pressure fans are very loud (100-115 dBA). A silencer on the inlet or outlet is standard for safety.
- Expansion Joint: To isolate vibration from the piping.
Potential Manufacturers (Global Examples)
When searching for "Customized Soda Ash Project Industrial High Pressure Fan Lime Blower," look for companies specializing in heavy-duty pneumatic conveying.
- Europe: Howden, Korfmann, TLT-Turbo (Siemens).
- USA: New York Blower, Cincinnati Fan, Robinson Fans.
- China/India: Zibo Hengding Fan Co. (specializes in mine and chemical fans), Zealux Engineering, or local centrifugal fan makers.
- Specialists: Fan manufacturers that focus on Cement, Mining, and Chemical industries will understand the "Lime Blower" requirement best.
Final Recommendation for your Project
- Don't underspecify the pressure. A lime blower needs a high pressure margin (safety factor of 1.2x to 1.3x over calculated system pressure).
- Demand a wear guarantee. Ask for a minimum of 8,000 operational hours before major impeller replacement.
- Balance is critical. High-speed fans with an unbalanced impeller due to lime buildup will fail immediately. Specify ISO 1940 G6.3 balance grade or better.
