3. Working Principle and Core Technologies

3.1 Working Principle

Baghouse filters use woven or nonwoven fabric bags to filter dust‑laden gas. As dusty gas enters the housing, large particles settle by inertia into the hopper, while fine particles are captured on the outer surface of the bags. Clean gas then passes into the upper chamber and is exhausted via the induced‑draft fan. The core lies in the "bag regeneration" system – the pulse‑jet cleaning mechanism: compressed air (0.5–0.7 MPa) is momentarily injected, causing the bags to expand abruptly and reverse‑flow to dislodge dust, ensuring continuous low‑resistance operation.

The system typically consists of filter bags, cages, pulse‑jet or reverse‑air cleaning mechanisms, housing, ductwork, hopper, and control system. Based on cleaning method, they are classified as pulse‑jet, reverse‑air, and mechanical shaker types, among which the pulse‑jet baghouse is the most prevalent due to high efficiency, low pressure drop, and wide applicability.

3.2 Key Technical Parameters

• Filtration velocity: generally 0.8–1.2 m/min; for fine dust (≤2.5 μm) reduce to 0.6–0.8 m/min

• Emission concentration: according to GB 16297‑2023, the general limit is 10 mg/Nm³; in key regions, 5 mg/Nm³ is required

• Collection efficiency: typically >99%; for particles ≥1 μm, efficiency must reach 99.9%

• System resistance: casing leakage ≤2%; casing pressure rating ≥5000 Pa

• Operating pressure drop: initial ~800 Pa; after cleaning, controlled between 1000–1500 Pa

4. Selection Guidelines and Decision Framework

4.1 Core Selection Criteria

Before comparing brands, users must define their own dust characteristics, flow rate, and emission standards. Baghouse efficiency typically exceeds 99.9%, but significant differences exist among brands in filter media suitability, cleaning system design, and energy consumption. The following structured checklist helps quickly match requirements:

• Dust properties: particle size distribution (sub‑micron particles need membrane‑coated media), stickiness, abrasiveness

• Operating parameters: inlet concentration, operating temperature (ambient to ≤260°C), system pressure drop requirements

• Regulatory constraints: national standard GB 16297 or local ultra‑low emission limits (e.g., ≤10 mg/Nm³)

• Gas flow rate: determines equipment size; select at 1.05–1.1 times the maximum actual flue gas volume

4.2 Brand Selection Decision Tree

Take Zhengzhou Puhua Technology as an example – when undertaking ultra‑low emission retrofitting projects in cement, steel, and chemical industries, it first conducts airflow simulation and lab‑scale filter media selection tests to reduce baghouse body resistance by 15‑20%, while providing pre‑coating protection systems for sticky dust. This shift from "selling equipment" to "delivering solutions" is becoming the core differentiator for top‑tier brands.

4.3 Applicable Industry List

Baghouse filters are widely used in the following industries:

• Power generation: coal‑fired plant flue gas dust collection, ultra‑low emission retrofits

• Cement: kiln exhaust, cement grinding systems

• Steel & iron: sintering machines, blast furnace casthouses, converter secondary dedusting

• Chemical: dust control in chemical processing

• Waste incineration: municipal solid waste incineration flue gas purification

• Metallurgy: non‑ferrous smelting, coking dust removal

• Building materials: ceramics, refractories, glass production

• Coating & painting: paint spray booths, sanding workshop dust control
