LCDM Long-bag Low-pressure Pulse Bag Filter

Designed, manufactured and installed by Anhui Tianshun for Inner Mongolia Xinyuan Silicon Materials Technology Co., Ltd. in January 2022, the LCDM system is a high-volume industrial bag filter for dust-laden gas generated during silicon production. This negative pressure dust collector uses low-pressure pulse-jet cleaning to maintain stable filtration, continuous dust discharge and convenient maintenance. As a large dust collector, it can be customized according to airflow, gas temperature, dust loading and required outlet emission levels.

Key Benefits of the LCDM Low-Pressure Pulse Bag Filter

Efficient Fine-Dust Filtration

The LCDM pulse bag filter uses long filter bags and optimized airflow distribution to capture fine industrial dust while maintaining stable filtration under continuous operation.


Stable Negative-Pressure Operation

Designed as a negative pressure dust collector, the system helps prevent dust-laden gas from escaping into the workshop and supports controlled gas collection across large production areas.


Reliable Pulse-Jet Cleaning

The low-pressure pulse cleaning system removes accumulated dust from the filter bags, helping control pressure drop and maintain the long-term performance of the pulse dust collector.


Modular and Easy to Maintain

The modular structure provides convenient access to filter bags, pulse valves and ash-discharge components, reducing maintenance difficulty and shortening planned downtime.



How Does the LCDM Pulse Bag Filter Work?

The LCDM pulse bag filter uses negative-pressure gas collection, long filter bags and low-pressure pulse cleaning to support continuous dust removal in high-volume industrial applications.


1. Dust-Laden Gas Collection

Dust-laden gas from the furnace or production line enters the collector through ducts under controlled negative pressure, helping prevent untreated gas from escaping into the workshop.


2. Filtration Through Long Filter Bags

The gas passes through filter bags, where fine particles are retained on the filter surface while cleaned gas enters the upper clean-air chamber.


3. Low-Pressure Pulse Cleaning

When dust accumulation increases system resistance, compressed air is released through the pulse valves to clean the bags. The removed dust falls into the hopper for collection or recovery.



Industrial Applications of the LCDM Pulse Bag Filter

The LCDM system is designed for industrial processes that generate large volumes of fine, dust-laden gas. As a customized furnace dust collector, it is particularly suitable for industrial silicon and ferroalloy submerged arc furnaces, where continuous gas collection and reliable filtration are required.

This high volume dust collector can also be configured for:

  • Industrial silicon smelting and processing

  • Ferroalloy and submerged arc furnaces

  • Silicon powder and microsilica collection

  • Steelmaking and metallurgical furnaces

  • High-dust material-processing lines

Each furnace bag filter is configured according to airflow, gas temperature, dust concentration, particle characteristics and required outlet emission levels.


FAQs About LCDM Pulse Bag Filters

  • What industries use LCDM pulse bag filters?

    LCDM systems are commonly used in industrial silicon, ferroalloy, metallurgy and other furnace applications that generate large volumes of fine dust-laden gas.

  • Why does the system operate under negative pressure?

    Negative-pressure operation helps draw dust-laden gas into the collector and reduces the risk of untreated dust escaping into the production area.

  • How are the filter bags cleaned?

    The system uses low-pressure pulse-jet cleaning. Compressed air is released through pulse valves to remove accumulated dust from the filter-bag surface.

  • Can the LCDM system be customized?

    Yes. The bag filter equipment can be configured according to the gas collection layout, airflow demand, dust characteristics, maintenance requirements and available installation space.
