Bag Filter Hydraulic Hose for Steel Plants

Types of Hydraulic Hose Construction for Bag filter
Due to the variety of hydraulic hose applications and the range of chemicals and pressures they will be subjected to, there are likewise a number of hydraulic hose constructions.

Reinforced: This type of hosing resembles the basic three-layer construction, but with extra buffers in the reinforcement layer, most often in the form of textile braid, wire braid, or wire helix material around the inner tube.
Coiled: Coiled hoses are semi-rigid hoses designed for expansion and easy storing. Because the hose is coiled, it can stretch in such a way that does not put unnecessary pressure on the hose materials.
Corrugated: Another method of increasing expansion and flexibility in a hose is to introduce corrugation. Corrugation manifests as small threads or folds in the material of the hose, somewhat like an accordion, that allow the hose to expand and compress without damaging the housing.
Articulated: Articulated hoses are hoses built in sections, with rigid shafts connected by flexible joints. The articulation allows hoses to turn corners or swivel around other components.
Multi-element: Hoses that involve multiple elements listed above are termed “multi-element hoses.”



Bagfilter Hydraulic Hose Construction
The basic hydraulic hose construction involves three layers. These layers help maintain a consistent and reliable flow of liquid while protecting the overall assembly from breaking down as a result of wear or abrasion.

Inner tube: The inner tube is designed to be compatible with the liquid it carries, allowing both free-flowing elasticity and pressure-resistant stress bearing. This tube is often made from PDFE (PTFE), thermoplastic, or synthetic rubbers.
Reinforcement layer: This layer surrounds the inner tube and is composed of a coiled or braided wire. This set up supports the tubing while protecting against tears.
Outer layer: This layer is made of rigid materials and is designed to protect the innards of the hose.

The iron and steel industry has a large amount of dust and soot emissions and its properties are diverse. The dust collectors used for dust and dust treatment include wet dust collectors, electrostatic precipitators and bag filter.

Because of the low dust removal efficiency, the wet dust collector has a large amount of water and generates secondary water pollution, and has basically been eliminated. The electrostatic precipitator has high efficiency, can reach 99.0%, temperature resistance is up to 350°C, resistance is small, about 200 Pa~300 Pa, and the processing air volume is large, reaching 106m3/h or more. It was used in steel industry, but due to its application ratio Resistance range 104 ~ 1010Ω.cm, due to changes in the physical and chemical properties of dust, and can not adapt to changes in process conditions and load. In the iron and steel industry, there are a large variety of dust and soot, with a large specific resistance change. Many specific resistances are beyond their applicable range, and some process conditions change greatly. As a result, their dust removal efficiency is unstable, often falling below 90%, resulting in frequent emission concentrations. Fluctuations, it is difficult to maintain the emission concentration of <100 mg/Nm3 for a long period of time under different working conditions. Therefore, it is rarely used so far.
