Dust Collector Air Filter Bag Higher Temperature , Steel Mill Blast Furnace Bag House

Dust Collector Air Filter Bag higher temperature , Steel Mill Blast Furnace Bag house

Description:

Nomex Filter Bags

Application:

Nomex Filter Bags are mainly used in steel Mill Blast Furnace dust collection , cement industry, asphalt industry, metallurgical industry and tobacco industry for flue gas purification.

Performance:

Continuous operating temperature is up to 200°C, instant service temperature is up to 240°C

Fire retardant performance is excellent

Corrosion resistance and alkali resistance is good

Excellent thermal stability, excellent abrasion resistance and flexural resistance Hydrolysis resistance is poor, frequent SOx and vapor in flue gas or dew point will greatly reduce its service life

Properties

1) Performs at high temperatures

Nomex filter bag  can be used continuously at operating temperatures up to 218°C (425°F) , and can handle higher temperature surges. However, to optimize dust filter  bag wearing  life, continuous temperatures of 204°C (400°F) and lower with minimum temperature surges are recommended.

2) Resists flexing and abrasion

Flex resistance of Nomex filter bag at room temperature is good, about equal to that of polyester fibers; after aging at temperatures of 121°C (250°F) and above its toughness if excellent. Nomex filter bag should give more than three times the wear life of polyester filter bags  at 121°C (250°F) and above.

3) Effect of moisture

Nomex filter bag  performs well at high operating temperatures with normal amounts of moisture. The wear life projections in the below graphs were developed using 6-10% H20. When operating in high moisture environments it would be worthwhile to investigate reduction of temperature to reduce wear life.

4) Resists Chemicals

Nomex filter bag  ,Aramid filter bag fier  resists attacks by mild acids, mild alkalis, and most hydrocarbons. In acid environments, evaluation of Nomex filter bags should be made to ensure that the fiber will perform acceptably before insulation. Nomex filter bag ,Aramid filter bag is  acid environment, at temperatures above the dew point, will outperform polyester. Temperature above the dew point should be maintained to minimize chemical attack on Nomex filter bag and the dust collector equipment.

5) High temperatures

The most effective use of Nomex filter bag ,aramid filter bag is in high efficiency filtering systems  where effluent temperatures are above 250°F or in  systems with surges over 250°F. In hot gas filtration systems. 

Filter bags, dust collector bag ,dust filter bag , dust bags, filter socks, - they all mean the same thing: An industrial grade fabric filter made from heavy duty material, all textile based, used in dust collecting systems, in either process filtration or pollution control.

The main type of dust filter bags including Nomex filter bag ,PPS filter bags ,P84 filter bag ,PTFE filter bags ,Acrylic filter bags ,Polyester filter bags,dust filter bag ,bag filters,dust collector bags.

Applications:

Nomex filter bag for higher temperature dust filtration ,widely applied in Asphalt mixing plant ,cement Kiln smoke dust filtration in cement plant ,steel melting furnace smoke filtration and so on .

NOMEX filter bag  offer one of the best total economies in a filtration system because of higher air to cloth ratios, higher temperature capability, and a long working  life.
