Outline

Equipment which treats pollutants such as harmful gases, chemicals, fumes and mists using a filter medium.

Principle

In a dust filtering and collecting facility, exhaust which contains dust is sucked into the facility through the inlet and filtered when it passes through a filter installed inside the facility before the purified air is discharged through the outlet.

DIsadvantages

• It is vulnerable to humidity.
• It is vulnerable to high temperature and acidic/alkaline dust.
• It has a risk of fire or explosion when collecting dust easily oxidizable.

Advantages

• It has a high dust collecting efficiency and can collect dust of various forms.
• It can treat dirty air with high concentration of dust.
• The form and capacity of the equipment can be changed depending on the process.
• It can be maintained at low cost.
• It can be continuously operated and the filtering speed can be adjusted.
• No white smoke is generated.
• It is free from any secondary pollution (generation of wastewater).
• Textile or pretreated granular bag filter can be used for high efficiency collection of dust and gas pollutants of size 1㎛ or smaller.
