Introduction

Because every dust filter has its own features and filter system parameters, select the filter medium must consider the following parameters: temperature, moisture, dust, gas, chemical properties, dust diameter, gas chemical property, dust grinding property, dust remover mechanism, such as cleaning manner, installations, etc. In general, the dust removal filter bag is used for industrial wasted gas filtration powder dust filtration, useful dust, high temperature gas dust removal, etc. for various kinds of dust removal equipment filter.

For dust removal filter bag specifications: diameter (mm) : ¢100, ¢120, 125, 130, ¢150 ¢, ¢¢180, ¢250, length: no limit; Special specifications can be customized.

Metamax high temperature dust filtration bag

Besides Metamax high temperature dust filtration bag made of polyester fibre has good spinnability and wearability, its biggest feature is the good heat resistance and flame retardant, and infusibility. Its fibre oxygen index is 29%, not self-ignition. In addition, it has good dimensional stability. Compared with glass fibre, its abrasion resistance, folding resistance is incomparable with fibreglass. It has high temperature resistance, long service life, so, selecting this bag is the priority for the high temperature filtration. It is mainly applied in flue gas purification in the cement industry, asphalt industry, metallurgical industry, and the tobacco industry , especially widely used in the asphalt industry.

PPS high temperature dust filtration bag

PPS filter felt is made of Germany imported polyphenylene sulphide (PPS) fibre according to the production process of high temperature resistant filter felt. It is the main high temperature resistance filtration materials. PPS needled felt has excellent performance in the application of the following situations.

  • The working temperature 170 ℃, short-time working temperature 232 ℃, melting point 285 ℃, limit oxygen index of 34 ~ 35.
  • Applicable at oxygen levels 15% or below
  • There is sulphur in the fuel or sulphur oxide in flue gas at the condition. The fibre has strong acid and alkali corrosion resistance, chemical resistance.
  • Contain moisture in the flue.
  • Under the condition of temperature 190 ℃ ~ 232 ℃ in the mining industry, the gas/ cloth ratio is at 5:1 in the on-line ash removal and gas/ cloth ratio at 6:1 in off-line ash removal , PPS filter bag proved to have excellent performance record. Widely used in power plant.

Anti-static dust filtration bag

In case of electrostatic discharge spark or external ignition factors, industrial dust after reaching certain concentration will easily cause explosion and fire, such as: flour dust, chemical dust, coal dust, etc. at electrostatic discharge condition. In the bag dust removal process, if bag is used to collect the dust, it must make dust filtering bag with antistatic property.

Good acid, weak alkali resistance, wear resistance, corrosion resistance, re-shaping feature

Polyester anti-static needle felt has smooth surface, good wear resistance, high strength. After twisting joint connection, it even has higher strength, better wear resistance, good air permeability and fast water leakaging, and convenient cleaning.
