1. Good dust removal effect
The ptfe filter bag has a good dust removal effect. The film is mainly used in combination with the needle felt through the hot laminating process. The surface is smooth and the filtering effect is good.
2. Wide use environment
Because this kind of Ptfe filter bag has strong high temperature resistance and chemical resistance, it has a very good effect on some high concentration and fine dust removal.
3. Good air permeability
The ptfe filter bag made of high temperature resistant material can directly penetrate gas, 3~7 cubic meters, which far exceeds the actual use requirements.
ptfe dust bag production standard:
The filter bag is made in strict accordance with the GB/T6719-2009 national standard to ensure the qualified rate of the product.
1. The bag mouth adopts elastic expansion ring and saddle pad made of the same material filter material to prevent the rubber ring from aging at high temperature and cause the filter bag to fall off.
2The stitching of the bag mouth adopts misalignment treatment to ensure that the bag mouth and the flower plate are closely attached to avoid dust leakage from the flower plate hole.
3 The needle distance of the filter bag is 25±1, the filter bag has no deviating, floating thread, and the comprehensive strength of the suture of the filter bag>1000N.
Important parameters of ptfe filter bag:
1: Acid and alkali corrosion resistance of the dust bag
When the coal-fired boiler dust collector starts or stops below the dew point, the waste SO2 reacts with the H2O molecules in the air to form sulfuric acid, which causes the fiber of the dust bag to deform and lose its strength. Therefore, when choosing a dust bag, you should consider a dust bag resistant to acid and alkali corrosion.
2: Filtration accuracy of dust bag
If the boiler dust filter filter gas speed * filter bag design standard, * will easily cause the fine dust in the filter bag fiber to get stuck, causing the filter bag to block. In response to this phenomenon, we can choose to cover the membrane filter bag or pre-cover the surface of the filter bag with protective dust.
3: Operating temperature of dust bag
If the waste temperature of the boiler dust collector is too high, the dust bag is easy to harden or melt, resulting in holes. Sparks or hot dust in the exhaust gas will also make the filter bag burn holes. Choosing the corresponding dust bag is very important for the operating temperature of the customer's boiler dust collector.
