Filter Bag Cage

Dust removal frame, also known as dust bag cage, is an indispensable accessory for bag filter, used as a frame of bag supporting cages. It can be compatible with six, eight, ten, twelve, sixteen, eighteen, two Ten or twenty-four tendons. The skeleton is the "rib" of the filter bag cages, and it is formed by a special welding equipment. Dust collector bags and cages are widely used in metallurgy, chemical industry, coking, power generation, non-ferrous metallurgy, steel, building materials, coal mines and other industries.

The characteristics of filter bag cage:

  • Firm welding: a smooth and straight appearance so that the filter bag is not damaged, the application is lightweight, easy to install and maintain, and the surface post-treatment process is electroplating or organic silicon processing.
  • Raw materials: high-quality low carbon steel wire, galvanized steel wire, stainless steel wire, etc.
  • Specifications: round, oval, flat, envelope type, trapezoidal, star, spring type and so on.
  • Structure: There are multi-section type, text type tube, protection short tube, unloading type, insert type and other reasonable structure.

Influencing factors of filter bag cage:

  • Effect of dust removal frame size: In the geometry of the dust removal frame, the diameter of the dust removal frame, the gas inlet, and the shape and size of the exhaust pipe are the most important influencing factors.
  • The influence of gas parameters on the performance of the dust removal framework: including the influence of gas flow rate, the influence of gas dust concentration, the influence of gas moisture content, the influence of gas density, viscosity, pressure, and temperature.
  • The effect of physical properties of dust on the dust removal framework.
  • The effect of dust on the inner wall roughness of the framework: Concentration of dust particles near the wall surface will cause swirling due to the rough surface, causing some dust particles to be thrown into the rising air stream and entering the exhaust pipe, which reduces the dust removal efficiency.

Baghouse filter cages production standard:

  • The cage-type dust removal frame requires a uniform distribution of supporting rings and longitudinal bars, and should have sufficient strength and rigidity to withstand the gas pressure of the filter bag in the state of filtering and cleaning, and can prevent the normal transportation and installation process from occurring. Damage and deformation caused by impact and impact.
  • Filter bag skeleton all welding points should be welded firmly does not allow off welding, welding and missed welding.
  • The surface of the filter bag frame and the filter bag should be smooth and smooth, do not allow welding, uneven and burr.
  • The tension spring type skeleton should have enough turns and elasticity, and the distance should be uniform after pulling open.
  • The surface of the filter bag skeleton must be treated with anti-corrosion, according to different needs of the plating, spray or paint, such as for high temperature, the corrosion should be clear to meet the use of temperature requirements.
  • Dust bag cage verticality 6M positive and negative 1mm.
  • Dust bag cage has an integral, sub-section of two or three sections.
  • Dust bag cage length of more than 3 meters wearing a steel molding pipe.
  • Dust bag cage galvanized, spray, silicone processing.
