1️⃣ What Is an Industrial Bag Filter System?

An Industrial Bag Filter System (also known as a baghouse dust collector) is a dry filtration system that removes particulate matter from industrial exhaust gases by passing air through fabric filter bags.

Dust particles are captured on the outer surface of filter media, while clean air exits through the outlet duct.

This technology is widely used in:

  • Cement kiln exhaust systems
  • Clinker cooler dust control
  • Fly ash handling plants
  • Lime production lines
  • Bulk material loading stations

👉  For reference on global emission regulations, see Environmental Protection Agency (EPA) standards.


2️⃣ How Does a Bag Filter Work? (Working Principle)

A bag filter operates based on surface filtration.

Working Sequence:
  1. Dust-laden air enters the chamber.
  2. Air passes through filter bags.
  3. Dust forms a dust cake layer.
  4. Pulse jet cleaning removes accumulated dust.
  5. Clean air is discharged through the stack.

A bag filter is a dry dust collection system that achieves over 99% filtration efficiency by using fabric filter media to separate particulate matter from gas streams.

👉  For workplace exposure references, see OSHA permissible exposure limits for dust (PNOR).


3️⃣ Air-to-Cloth Ratio Design (Critical Engineering Parameter)

The air-to-cloth ratio determines filtration velocity.

Formula:

Filter Area = Airflow (m³/h) ÷ Filtration Velocity (m/min × 60)

Typical value in cement plants:

0.8 – 1.2 m/min

An excessively high air-to-cloth ratio leads to rapid pressure rise, short bag life, and increased fan energy consumption.

👉  For bulk material handling design references, see CEMA (Conveyor Equipment Manufacturers Association).


4️⃣ Pressure Drop Analysis

Normal operating pressure drop:

1200 – 1800 Pa

High Pressure Drop Causes:
  • Excessive dust loading
  • Insufficient pulse cleaning
  • Moisture condensation
  • Incorrect filtration velocity

High pressure drop in a baghouse is usually caused by excessive dust accumulation or improper cleaning cycle settings.


5️⃣ Types of Industrial Bag Filters

Pulse Jet Bag Filter
  • Compact structure
  • Continuous online cleaning
  • Most common in cement plants
Reverse Air Bag Filter
  • Suitable for high temperature gas
  • Larger footprint
Shaker Type Bag Filter
  • Small systems only

Bag Filter for Industrial Dust Collection

FAQ Section

What is the efficiency of an Industrial Bag Filter System?

An industrial bag filter system can achieve filtration efficiency above 99% when properly designed and maintained.

What causes high pressure drop in a baghouse?

High pressure drop is caused by excessive dust cake formation, improper cleaning cycle settings, or high filtration velocity.

When should a bag filter be used instead of a cyclone?

A bag filter should be used when fine particulate removal and strict emission standards below 30 mg/Nm³ are required.

How long do filter bags last in cement plants?

Filter bags typically last between 2 to 3 years depending on temperature, dust abrasiveness, and maintenance frequency.


Sistem Industrial Bag Filter untuk Pabrik Semen

Industrial bag filter system adalah sistem penyaring debu kering yang digunakan untuk mengontrol emisi debu pada pabrik semen dan industri material curah.

Sistem ini bekerja dengan prinsip filtrasi permukaan, di mana udara berdebu melewati kantong filter dan partikel tertahan di permukaan kain.

Keunggulan utama:

  • Efisiensi filtrasi lebih dari 99%
  • Cocok untuk standar emisi < 30 mg/Nm³
  • Desain rasio air-to-cloth optimal
  • Umur pakai kantong 2–3 tahun

Sistem ini sangat cocok untuk kiln exhaust, clinker cooler, dan silo semen.
