# Industrial Specification: Bag Filter House

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

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-1.2 kPa differential pressure across filter media**. Failure boundary: **Structural failure at 3.5 kPa internal pressure differential or 150°C sustained temperature**, Mechanism: **Yield strength exceedance of structural steel (ASTM A36, 250 MPa yield) at pressure differentials &gt;3.5 kPa, or thermal expansion mismatch between steel housing and filter media at temperatures &gt;150°C**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| f | Friction Factor | Engineering Constant |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Pulse cleaning system malfunction causing 0.8 MPa compressed air pressure instead of 0.6 MPa design pressure | 8 | Filter bag rupture at seam welds due to excessive reverse pulse force | Install pressure relief valve set at 0.7 MPa in pulse air line with mechanical interlock |
| Condensation formation due to gas temperature dropping below dew point (65°C for typical flue gas) | 8 | Filter media blinding from hygroscopic dust agglomeration, increasing pressure drop to 2.5 kPa | Integrate gas preheater maintaining inlet temperature at 75°C minimum with PID control |

## 3. Key Technical Parameters

- **Caution**: 

### Q: What materials are available for bag filter houses in machinery manufacturing?
**A**: Our bag filter houses are constructed from durable carbon steel or corrosion-resistant stainless steel, suitable for various industrial environments and particulate types.

### Q: What components are included in a standard bag filter house assembly?
**A**: 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.

### Q: How does a bag filter house function in off-gas cleaning systems?
**A**: 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.

## 6. Manufacturing Compliance
