Pulverized Coal Filter GLQ-2

Technical Specification for Pulverized Coal Filter Produced by Xiangye
1. Overview
The pulverized coal filter is a high-efficiency, compact industrial device, mainly used in pneumatic conveying systems for pulverized coal, ensuring unobstructed pipelines and preventing blockages caused by impurities. Its core function is to physically filter foreign matter from pulverized coal, ensuring the continuous and stable operation of systems such as blast furnace coal injection, and is widely applied in fields like metallurgy and petrochemicals.

2. Structure and Materials
- Main Structure:
- Material: The outer shell is made of carbon steel, with a wear-resistant coating added to the inner layer to enhance anti-wear performance.
- Design: Double-cone butt-welded structure, with optimized internal airflow angle design to reduce flow resistance and wear.
- Core Filter Components:
- Filter Plate: Made of high-wear-resistant manganese steel, with high-efficiency separation capability, capable of filtering coarse particles and impurities.
- Modular Design: The filter plate is detachable, supporting quick replacement and reducing maintenance downtime.



3. Working Principle
The pulverized coal filter is installed after the air supply regulator at the outlet of the injection tank, and realizes impurity separation through the following process:
1. Gas-solid mixture flow passes through: The pulverized coal airflow containing impurities enters the filter housing.
2. Inertial separation: With the help of the internal airflow angle design, the pulverized coal flows along a stable path, reducing turbulence.
3. Filtration: The manganese steel filter plate intercepts large-particle impurities, and the purified pulverized coal continues to be conveyed to downstream equipment.
4. Impurity collection: The separated impurities settle at the bottom, and are cleaned regularly to avoid secondary pollution.



4. Application Scenarios
- Blast Furnace Coal Injection System: Mainly used to protect distributors, coal injection branch pipes and valves, preventing blockages.
- Key Protection Nodes: Installed after the air supply regulator, serving as the last barrier before pulverized coal enters the pipeline.
- Industry Coverage: Metallurgy (steel smelting), petrochemicals (coal chemical industry), electric power (coal-fired power generation) and other fields requiring pneumatic coal conveying.
5. Technical Advantages
- High-Efficiency Filtration: The manganese steel filter plate has strong wear resistance and high separation accuracy, ensuring the purity of pulverized coal.
- Stable Operation: Optimized airflow structure reduces pressure loss, avoiding the risk of pipeline blockage.
- Convenient Maintenance: The modular filter plate design supports quick replacement, reducing labor costs and downtime losses.
- Long-Life Design: The carbon steel shell and wear-resistant inner layer extend the service life of the equipment, with remarkable comprehensive cost-effectiveness.

6. Maintenance and Management
- Regular Inspection: Monitor the differential pressure of the filter plate to judge the blockage status, and clean or replace it in time.
- Impurity Cleaning: Remove sediments through the bottom slag discharge port to keep the system unobstructed.
- Spare Parts Management: Stock vulnerable parts such as manganese steel filter plates to shorten the emergency maintenance response time.
7. Conclusion
With its sophisticated design, high-efficiency filtration and easy maintenance characteristics, the pulverized coal filter has become a key equipment in modern industrial pulverized coal conveying systems. Its application not only improves production continuity, but also provides reliable technical support for high-energy-consumption industries by reducing failure rates and maintenance costs. In the future, with the development of materials science and fluid mechanics, Xiangye's performance and adaptability are expected to be further optimized.
