Pulverized coal filter GLQ-2

Technical Specification of Pulverized Coal Filter Produced by Xiangye
1. Overview
The pulverized coal filter is an efficient and compact industrial equipment, mainly used in pneumatic conveying systems for pulverized coal, to ensure unobstructed pipelines and prevent blockages caused by impurities. Its core function is to physically filter foreign substances in 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 petrochemical industry.

2. Structure and Materials
- Main Structure:
- Material: The outer shell is made of carbon steel, with a wear-resistant coating added on 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: The pulverized coal airflow containing impurities enters the filter shell.
2. Inertial separation: With the help of internal airflow angle design, the pulverized coal flows along a stable path to reduce turbulence.
3. Filtration: The manganese steel filter plate intercepts large-particle impurities, and the purified pulverized coal is continuously 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 branches and valves, preventing blockages.
- Key Protection Nodes: Installed after the air supply regulator, serving as the final barrier before pulverized coal enters the pipeline.
- Industry Coverage: Metallurgy (steel smelting), petrochemical industry (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 equipment's service life, with significant comprehensive cost-effectiveness.

6. Maintenance and Management
- Regular Inspection: Monitor the differential pressure of the filter plate to determine 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 repair response time.
7. Conclusion
With its exquisite 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 equipment is expected to further optimize its performance and adaptability.
