Technical Definition & Core Assembly

A canonical Bag Filter House is characterized by the integration of Filter Bag Cage and Access Door. In industrial production environments, manufacturers listed on CNFX commonly emphasize Carbon Steel construction to support stable, high-cycle operation across diverse manufacturing scenarios.

The structural housing that contains filter bags and provides the enclosure for dust collection in an off-gas cleaning system.

Product Specifications

Technical details and manufacturing context for Bag Filter House

Definition
The Bag Filter House is the main structural component of a bag filter system within an Off-gas Cleaning System. It serves as the enclosure that houses the filter bags, provides the necessary volume for gas flow distribution, collects the filtered dust in hoppers, and maintains the pressure differential required for efficient filtration. It typically includes compartments, access doors, inspection ports, and support structures for the filter bags.
Working Principle
Dust-laden off-gas enters the Bag Filter House and flows through filter bags. Dust particles are captured on the exterior surface of the bags, while clean gas passes through the fabric and exits the system. The collected dust accumulates in hoppers at the bottom of the house for periodic removal.
Common Materials
Carbon Steel, Stainless Steel
Technical Parameters
  • Dimensions (length × width × height) of the housing structure (mm) Customizable
Components / BOM
  • Filter Bag Cage
    Supports filter bags and maintains their shape during operation
    Material: Galvanized Steel
  • Access Door
    Provides entry for maintenance and filter bag replacement
    Material: Carbon Steel
  • Dust Hopper
    Collects and stores filtered dust for removal
    Material: Carbon Steel
  • Tube Sheet
    Plate that separates clean gas and dirty gas compartments, with holes for filter bag installation
    Material: Carbon Steel
Engineering Reasoning
0.5-1.2 kPa differential pressure across filter media
Structural failure at 3.5 kPa internal pressure differential or 150°C sustained temperature
Design Rationale: Yield strength exceedance of structural steel (ASTM A36, 250 MPa yield) at pressure differentials >3.5 kPa, or thermal expansion mismatch between steel housing and filter media at temperatures >150°C
Risk Mitigation (FMEA)
Trigger Pulse cleaning system malfunction causing 0.8 MPa compressed air pressure instead of 0.6 MPa design pressure
Mode: Filter bag rupture at seam welds due to excessive reverse pulse force
Strategy: Install pressure relief valve set at 0.7 MPa in pulse air line with mechanical interlock
Trigger Condensation formation due to gas temperature dropping below dew point (65°C for typical flue gas)
Mode: Filter media blinding from hygroscopic dust agglomeration, increasing pressure drop to 2.5 kPa
Strategy: Integrate gas preheater maintaining inlet temperature at 75°C minimum with PID control

Application Fit & Sizing Matrix

Operational Limits
pressure: -5000 to +5000 Pa (typical differential pressure)
flow rate: Up to 500,000 m³/h (depending on size)
temperature: -20°C to 200°C (depending on material)
slurry concentration: Up to 500 g/m³ (dust loading)
Media Compatibility
✓ Polyester filter media (for general dust) ✓ PTFE membrane (for high temperature/chemical resistance) ✓ Stainless steel housing (for corrosive environments)
Unsuitable: High moisture environments with condensation below dew point
Sizing Data Required
  • Total gas flow rate (m³/h)
  • Dust loading concentration (g/m³)
  • Required collection efficiency (%)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Filter bag blinding
Cause: Excessive moisture causing hygroscopic dust to cake on bags, improper pulse-jet cleaning parameters, or condensation from compressed air
Bag seam failure
Cause: Mechanical stress from improper tensioning, abrasive dust particles, or thermal cycling weakening seams
Maintenance Indicators
  • Sustained high differential pressure (>150% of design) across filter house indicating reduced airflow
  • Visible dust emission from clean air outlet or audible 'hissing' from torn bags during operation
Engineering Tips
  • Implement moisture control in compressed air system with refrigerated dryers and maintain dew point 20°F below ambient temperature
  • Establish bag tensioning protocol with torque specifications and install differential pressure monitoring with automated alarms

Compliance & Manufacturing Standards

Reference Standards
ISO 16890:2016 - Air filters for general ventilation ANSI/ASHRAE 52.2-2017 - Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size DIN EN 779:2012 - Particulate air filters for general ventilation - Determination of the filtration performance
Manufacturing Precision
  • Filter bag seam strength: +/-5% of specified tensile strength
  • Filter bag dimensional tolerance: +/-2mm on length and width
Quality Inspection
  • Pressure drop test at rated airflow
  • Filter efficiency test using particle counting method

Frequently Asked Questions

What materials are available for bag filter houses in machinery manufacturing?

Our bag filter houses are constructed from durable carbon steel or corrosion-resistant stainless steel, suitable for various industrial environments and particulate types.

What components are included in a standard bag filter house assembly?

A complete bag filter house includes the structural housing, filter bag cages, access doors for maintenance, dust hopper for collected particulate, and tube sheet for bag mounting and sealing.

How does a bag filter house function in off-gas cleaning systems?

The bag filter house encloses filter bags that capture dust and particulates from exhaust gases. Contaminated air enters, particles are trapped on bag surfaces, and clean air exits through the system.

Can I contact factories directly on CNFX?
