Lanhao produces pulverized coal filters. The following are the core technical points and selection guide for pulverized coal pipeline filters in steel plants, integrating industrial standards and industry practices:
I. Core Functions and Positioning
Core Role
Filters out coarse particles, fibers, wood chips, and other impurities in pulverized coal to prevent clogging of distributors, spray guns, and valves, ensuring continuous operation of the blast furnace pulverized coal injection system.
The designed filtration area is ≥4 times the cross-sectional area of the inlet pipeline, reducing conveying resistance and minimizing wear.

 
II. Key Structure and Technical Parameters
Item
Specification Requirements
Structural Design
Double-cone butt-welded chamber with removable wear-resistant manganese steel filter plates (carbon steel shell + ceramic/wear-resistant lining)
Connection Method
Flange connection (DN40-DN150), horizontal installation
Working Pressure
1.0/1.6/2.5 MPa (selected based on system pressure)
Maximum Temperature Resistance
≤100°C
Filtration Accuracy
≥0.5mm particles and fibrous impurities
Typical Application Location: Installed after the injection tank outlet air supplement regulator and before the distributor.
