1. Product Overview

The Long Bag Low Pressure Pulse Fabric Filter is a dust collector that removes suspended particulate matter from flue gases using fabric filter bags combined with pulse-jet cleaning technology. The long bag design provides a larger filtration area, allowing for higher dust collection capacity while maintaining low pressure drop.

Key Features:

  • High Dust Collection Efficiency: Captures up to 99.9% of fine particles.

  • Low Pressure Operation: Reduces energy consumption while maintaining performance.

  • Pulse-Jet Cleaning: Automatic cleaning using short bursts of compressed air to maintain filter efficiency.

  • Long Bag Design: Maximizes filtration area, extends bag life, and reduces maintenance.

  • Durable Fabric Materials: Resistant to high temperatures, abrasion, and chemical corrosion.

  • Modular and Customizable: Can be adapted to various gas flow rates, temperatures, and dust loads.

  • Environmental Compliance: Ensures emissions meet local and international standards.

2. Working Principle

  1. Filtration Stage:
    Dust-laden gas enters the filter housing and passes through the fabric bags. Particulate matter is captured on the surface of the fabric, while clean gas passes through and exits the collector.

  2. Pulse Cleaning Stage:
    Short bursts of compressed air (pulses) are injected into the bags, loosening the dust cake accumulated on the bag surface.

  3. Dust Collection Stage:
    The loosened dust falls into the hopper below for disposal, ensuring continuous filtration.

  4. Continuous Operation:
    The low-pressure design and pulse-jet cleaning allow for uninterrupted filtration with minimal pressure drop, maintaining efficient operation over long periods.

3. Product Advantages

  1. High Filtration Efficiency
    Removes fine dust particles effectively, protecting the environment and equipment.

  2. Energy-Efficient Operation
    Low-pressure design reduces fan power requirements and operational costs.

  3. Durable and Long-Lasting
    High-quality filter fabric and long bag design increase lifespan and reduce maintenance frequency.

  4. Automatic Pulse Cleaning
    Keeps filtration efficiency high without manual intervention.

  5. Wide Industrial Applications
    Suitable for cement, steel, power plants, chemical, biomass, and other industries.

  6. Modular and Customizable
    Can be designed according to gas flow, temperature, and dust characteristics, making it highly adaptable.

  7. Environmental Compliance
    Ensures emission standards are met, reducing environmental impact and improving corporate responsibility.

4. Applications and Usage

Long Bag Low Pressure Pulse Fabric Filter is ideal for:

  • Cement Industry: Capturing cement dust from kilns, mills, and conveyors.

  • Steel Manufacturing: Removing iron dust, smoke, and particulates from sintering and rolling operations.

  • Power Plants: Controlling fly ash and soot from coal-fired, biomass, or waste-to-energy boilers.

  • Chemical Industry: Removing fine dust, powders, and chemical particulates from production processes.

  • Biomass Industry: Collecting ash and dust from biomass combustion and gasification.

How to Use:

  1. Install the filter along the exhaust duct or gas outlet.

  2. Connect to compressed air supply for pulse-jet cleaning.

  3. Start the filtration system and monitor pressure drop and emission levels.

  4. Adjust pulse frequency and duration according to dust load.

  5. Periodically inspect filter bags and hopper for maintenance.

5. Case Study: Cement Plant Dust Control

A cement manufacturing plant installed Long Bag Low Pressure Pulse Fabric Filters on its clinker cooler and mill exhaust lines. Within six months:

  • Dust collection efficiency exceeded 99.5%, meeting strict environmental regulations.

  • Energy consumption decreased by 20% due to low-pressure operation.

  • Maintenance frequency reduced, as the long bag design and pulse cleaning minimized downtime.

  • Operational safety improved, reducing airborne dust in production areas.

This demonstrates that long bag low-pressure pulse fabric filters provide high-efficiency dust control, energy savings, and operational reliability.

6. Solving Customer Pain Points

Common challenges in dust control include:

  • High dust emissions exceeding environmental limits

  • Frequent maintenance of traditional dust collectors

  • High energy consumption

  • Inefficient removal of fine particles

  • Compliance risk with local or international regulations

Long Bag Low Pressure Pulse Fabric Filter Solutions:

  • Captures fine and submicron dust effectively
