Metal Fiber Filter Bag for High Temperature Flue Gas and Dust Removal

 1. The characteristics of metal fiber high temperature dust collector bags

 

The metal fiber high temperature dust collector bag is made of micron-sized metal fiber sintered filter material as raw material, and is welded. The metal fiber sintered felt filter medium is composed of a three-layer composite of metal plate mesh, coarse metal fiber and fine metal fiber. Vacuum sintered into a whole to form a three-dimensional network structure.

 

High temperature dust collector bags have the characteristics of high porosity, large specific surface area, uniform pore size distribution, high dirt holding capacity, and high filtration accuracy. In addition, it has high temperature resistance, corrosion resistance, high efficiency, low emission concentration, low operating resistance, long life, renewable, energy saving and other advantages, with excellent filtering performance, which is ideal high-temperature flue gas dust removal filter material, and has been widely used in industrial smoke In the field of gas dust removal, especially in high temperature, strong corrosion and harsh working conditions such as chemical industry, metallurgy, building materials, electric power, petroleum, and new energy.

 

2. Material and scope of application of metal fiber high temperature dust collector bags

 

When the operating temperature is less than 400℃, 304 and 316L materials can be selected, 304 material has good temperature resistance, 316L material has better temperature resistance and better corrosion resistance;

 

When the operating temperature is 400-600℃, 310S and 314 materials can be selected, which have the ability to resist high temperature oxidation;

 

When the high temperature is greater than 600°C, iron-chromium-aluminum materials can be selected; other materials such as Hastelloy and nickel are available as required.

 

Technical advantages:

 

High temperature resistance, corrosion resistance, high strength, wear resistance, no perforation, no break;

 

High filtration precision, high dust removal and interception efficiency, can meet the ultra-low emission requirements, and the emission concentration of particulate matter <5mg/Nm3;

 

Good air permeability, low resistance, low operating energy consumption, high wind speed;

 

Easy to clean dust, online back-blowing and offline cleaning, long service life, good filter bag regeneration performance;

 

It can be recycled and processed without causing secondary pollution to the environment;

 

Good conductivity, to avoid accidents caused by static electricity, flameproof and explosion-proof;

 

Long service life, the product life can be as long as 3 to 5 years, which is 4 to 6 times the service life of cloth bags.

The Electromagnetic Valve 2019

Electromagnetic pulse valves (also known as diaphragm valves) are compressed air "switches" for pulse bag filter dust cleaning systems. By the control of the output signal of the pulse jet control instrument, the filter bag is cleaned by one row (chamber), so that the resistance of the filter is kept within the set range, so as to ensure the processing capacity and dust collection efficiency of the filter. DMF-Z electromagnetic pulse valve  is a right-angle valve, and the angle between the inlet and outlet is 90 degrees, which is suitable for the installation connection between the airbag and the dust blower tube. The air flow is unobstructed and it can provide the required clear air pulse. DMF-ZM electromagnetic pulse valve is the same as the "Z" series of the right-angle valve, suitable for airbag and dust collector spray pipe installation connection, the import and export of the two ends with a fixed nut for installation so that installation and us...

Needle Felt Filter Bags

Anti-Static Polyester Needle Felt Bag Anti-static dust bag is currently ideal dust filter material, with good ventilation energy, high dust removal efficiency, and a certain degree of acid, alkali and heat resistance, weaving process uses a multilateral brushing, increased fabric thickness, elasticity, so the dust removal effect is good, the dust removal rate can reach 99.99%. The above two products have been widely used in petroleum, chemical, metallurgy, mining, cement and environmental protection dust removal and other industries. In addition to the process of producing a normal needle felt, the production of a polyester anti-electrostatic dust bag also requires the incorporation of conductive fiber yarns in warp yarns of base fabrics for the production of needle felts or the incorporation of conductive fibers and the like in chemical fibers. After the (ie explosion limit) in the event of static discharge sparks or external ignition and other factors, can easily lead to explo...

Pneumatic Plug Valve

  P neumatic plug valve  is a main control equipment for the flow or delivery of powder, crystal grain, granular materials and small pieces of material. It is widely used in metallurgy, mining, building materials, food, chemical industries to control flow changes or cut off quickly. Pneumatic flapper valve has the advantages of simple structure, flexible operation, light weight, no jamming, and is especially suitable for the transportation and flow regulation of all kinds of solid materials and about 50mm block and lump materials. The installation is not limited by the angle and is easy to operate. Can adjust the scale at any time.   Structural features: Simple structure, flexible operation, light weight, no jamming, fast cutting, especially suitable for all kinds of non-viscosity solids, powders and granules less than Φ10mm, the transportation of crystal grain and flow regulation, installation is not limited by the angle , Easy to operate, can adjust the opening degree a...
