FTP Fume Treatment Plant

The electric furnace flue gas is collected through a gas collection hood and enters the main pipeline. Sparks in the exhaust gas are extinguished through a flame arrester, and then the exhaust gas enters the bag dust removal system. From the inlet of the bag dust collector, dust gas enters the filter area of the warehouse, and the remaining dust enters the filter area evenly with the airflow. The filtered clean gas enters the box through the filter bag. Lift valve. The exhaust pipe is discharged and then discharged to the dust standard through an induced draft fan.


Working Principle of EAF Dust Removal System

  • Pre treatment: Use a wet or dry dust collector to remove smoke and harmful gases.

  • Filtration: Filter particulate matter, harmful gases, and suspended solids to purify air.

  • Purification: Remove harmful gases, toxins, odors, etc.


Composition of Electric Furnace Dust Removal System

The electric furnace bag dust collector consists of a shell, a filter bag, an ash hopper, an ash discharge device, a bracket, and a pulse cleaning system.

The electric arc furnace dust collector is composed of a box assembly, a filter bag assembly, a guide device, a pulse blowing system, an ash discharge system, a control system, an offline protection system, etc.

The larger the volume of the electric furnace dust collector, the better. This should be based on the on-site operation situation to handle the airflow of the fan and determine the size of the fan model. If the fan is too large, the service life of the shell and accessories of dust collectors of types of steel making furnaces will be greatly damaged. If the fan model is too small, the electric furnace dust collector cannot work properly, and the wind speed inside the pipeline cannot meet the requirements. The pipe may cause blockage. Therefore, selecting the fan of the electric furnace dust collector reasonably can effectively ensure the normal and stable operation of the dust collector and ensure dust removal efficiency.

It is important to maintain sufficient draft on the furnace for the following reasons:

1. To provide adequate pollution control.

2. Excessive shop emissions make it difficult for the crane operator to charge the furnace.

3. Excessive emissions around the electrode ports can result in damage of hoses, cables, the electrode holder, the furnace delta, roof refractory, accelerated electrode wear, damage to the electrode spray cooler etc.

4. Emissions at the roof ring can result in warping of the roof ring structure.

5. Excessive emissions of carbon monoxide to the secondary canopy system may result in explosions in the ductwork downstream.

6. Excessive dust build-up may cause arcing between electrode phases. Most DES systems consist of water-cooled duct, spray cooling, dry duct and mayor may not have a dedicated DES booster fan.
