Product Details

FMS 9806 Fiberglass needle punched fabric DN 130x6000mm dust filter bag

 

 

FMS 9806 type dust filter bag is the most suitable material used in blast furnace dry gas cleaning system. it can be worked in different blast furnace dry GCP plant, 350-5000 m3 BF dry GCP.

 

This kind fabric is needle punched by 3-4 fibers together, it has high temperature repellent, good air permeability, easy to take offer cake advantage. Now widely used in dry GCP system.

 

The detail description of filter medium

 

For reducing resistance of filter media, except the special technology for laying the fiber , we also choose different diameter fiber to process, let’s the fabric can be graded structure, on the fabric surface ,there is super fine fiber, to increase the fabric filtration precision ,anti-acid and alkali ,and en-length the life of fabric. In the actual application , the efficiency as same as membrane coating fabric , but resistance is more lower.

 

1) Nonwoven fabric cross section choose graded structure , fiber diameter from thin to thick, there are 4 layers, surface super fine fiber layer--super fine fiber---scrim—thick fiber layer. The fiber more thin, the ventilation channel more compact.

 

Working condition

 peak temperature  300 degree instant
 Filtration speed  < 0.6 m/min
 outlet dust demand  < 5mg/Nm3
 Diameter of the tube plate   DN 135mm
 Filter media FMS 9806  Superfine fiberglass and P84 compounded fabric
 Treatment PTFE membrane,heat setting
  Bag size  DN130X6000 mm

 

Filter fabric structure

From up( face to ash) to down

Surface: Polyamides+ Fiberglass layer

 fiber dipping and PTFE coating

Main part: Polyamides + Fiberglass layer

Scrim: high tensile fiberglass woven fabric

Post surface: Polyamides +Fiberglass layer

 

2) Learning from the technology of membrane fabric.

 

We change the same diameter fiber to different diameter fiber, then blended together, turn the traditional filter media to graded structure filter media.

The method of filtration from “ surface layer +deep layer” to “surface layer” only. The super fine fiber layer can resistance smaller particles, the nonwoven fabric surface will be more compact, and easy to remove ash cake.

 

Surface filtration (b)surface +deep layer filtration (c) surface layer filtration

 

(1) Graded structure filter media

(2) traditional filter media 

(3) Suitable filter media for India Blast furnace

 

While we visited and communicated with many India blast furnace, we found the dry GCP is most popular in small volume blast furnace ,less than 1000m3 .

 

China has full experiences in the operation of dry GCP ,and the filter bags are very maturity in operation.

FMS® is the first stage filter bags in dry GCP coming with the projects, we here come to introduce this kind material to you again and solve the filtration problem during operation.
