Pulse jet baghouse technology is a significantly advanced technology in industrial air pollution control systems. A Pulse Jet Baghouse or Reverse Pulse Jet Baghouse (PJBF or PJF) functions like a filter, where air or gases are passed through a series of fabric filter bags, where these filters capture particles while allowing clean air to pass through.

These filters are made of materials such as felted or woven fabric, fiberglass, and other synthetic materials. The material selection widely depends on factors such as temperature, chemical composition of the particulates, and operational requirements.

Advantages of pulse jet baghouse:

  • Low maintenance: cleaned by a short burst of compressed air injected through a common air manifold over a row of bags
  • High Efficiency: Pulse jet systems provide high filtration efficiency
  • Adaptability: Pulse jet baghouses can be adapted to various industrial applications and are suitable for a wide range of particulate types and sizes.
  • Environmental Compliance: By effectively controlling emissions, pulse jet baghouse systems help industries comply with environmental regulations and standards.

Types of pulse jet baghouse we offer:

1. Online Baghouse

ESP - Electrostatic Precipitator

In an online baghouse, filter bags are supported by a metal cage, which is fastened on a laser-cut tube sheet plate at the top of the baghouse. Dirty gas enters from the bottom of the baghouse and flows from outside to inside the bags. This process allows the capture of dusty particles on the outer surface of the bags. Bags are cleaned by a short burst of compressed air injected through a common air manifold over a row of bags for a short time, which acts as a rapidly moving air bubble, traveling through the entire length of the bag and causing the bag surfaces to flex. This flexing of the bags breaks the dust cake, and the dislodged dust falls into a collection hopper below.

 

Applications of Online Baghouse Systems:

  • Industrial Boiler Exhaust flue gas
  • Material handling systems
  • Capturing nuisance dust in plants

 

Ecomak’s online pulse-jet baghouses offer:

  • Volumes ranging up to 1,00,000 Am3/hr
  • A wide variety of applications ranging from milk powder to uranium ore

2. Offline Baghouse

In an offline pulse jet baghouse, the construction and working are similar to the online baghouse.

 

The offline Pulse jet Baghouse consists of a number of modules/chambers. Each module is isolated from a gas stream by closing its outlet poppet damper in a predetermined sequence. In an isolated module, each of the filter bag rows is cleaned sequentially by compressed air pulses. The mass of air also draws air behind it, adding to the downward airflow.

The dust removed falls into the hoppers and is discharged through the discharge valve. A master controller – which can be Programmable Logic Controller (PLC) based dictates the sequence of the chambers that should go in “Offline Mode”.

 

Applications of offline Baghouse systems:

  • Steel
  • Cement
  • Power

 

Ecomak’s Offline Pulse-jet baghouse is used for PRIMARY and SECONDARY Ventilation applications.
