Hot Gas Filter Bag

Product

Hot Gas Filter Bag processes metal wires into metal fibers through a cluster drawing. The metal fibers are then made by non-woven fabric laying, high-temperature sintering, and other processes and then welded. The hot gas metal fiber filter bag comprises layers of fibers with different pore sizes to form a gradient three-dimensional porous structure, and the fibers are welded structures.

Hot Gas Filter Bag

The micropores are not easily deformed, the filtration efficiency is stable, and the filtration resistance is low. Designed and manufactured to precise bubble point specifications, tight thickness tolerances, and permeability uniformity, ensuring reliable filtration performance, effective backwash, and long operating life. As one of the top-performing Gasification Filters, it is an ideal choice for high-temperature flue gas dust removal applications.

The standard structure of standard hot gas cleaning filters uses a core support layer of perforated porous tubes to meet the strength requirements. One end is closed, and the other is open. A flange is welded at the open end to facilitate installation and fixation and ensure the sealing of high-temperature synthetic gas.

Metal Fiber Cartridge Manufacturing Process

Filter Layer Construction Type

Hot gas filter bag is a porous filter bag for depth filtration. It is made of bundle metal fibers by sintering in high temperature and welding after special non-woven laying and stacking with the pore gradient formed by layers of different pore sizes. Our filter media are composed of a metal cage skeleton, coarse metal fiber layer and fine metal fiber layer. It is widely used in various industries involving high temperature flue gas dust removal due to its excellent resistant to high temperature and corrosion.

Hot Gas Filter Bag

Features of metal fiber filter bag

Large dust removal capacity: 2 times dust removing performance of a dust bag made of PPS.

High filtration accuracy: The dust content after purification is ≤ 5 mg/Nm3.

Wear resistance: Its metal structure offers great wear resistance and a higher wear resistant coefficient when compared with other glass fiber materials, delivering a longer service life.

Filter body tensile strength: ≥ 1400 N/(5 cm × 20 cm).

Gas permeability: ≥ 100 L/dm2.min (1,000 Pa).

Allowable usage temperature: ≤ 450 °C.

Good electrical conductivity: Made of sintered metal power, it has better electrical conductivity than that of fiber dust bags as it does not generate static electricity like fiber dust bags during the filtration process.

Corrosion resistance: It can work in strong corrosive gases containing SO2, SO3, HCL, HF, etc.

Yes. By working closely with clients, design filter levels, operating parameters, dimensions, and styles.

Our experienced team of professional engineers is dedicated to developing the best filtration solutions, from initial conceptual design to manufacturing and validation, and then to service support.

Each of our filters or filtration systems fully meets the specified requirements, all of which are recorded as recognition of our work quality.

Yes, we have ISO certificates and patent certificates.

With the help of pressurized water or air backwashing, you can clean your industrial water filter. Therefore, if the water is highly polluted, such as rivers or groundwater, it takes 2-3 days to clean the filter. But if the water is clean, it can be cleaned in 2-3 weeks. In some filter systems, there is an automatic backwash system that automatically cleans the filter when it becomes clogged.

There are many ways to keep you going. Maintenance is crucial for industrial water filters to achieve sufficient filtration and long-term use. To avoid being shut down, you must clean and replace your filter element according to the manufacturer's instructions.

Plan to regularly inspect the internal screen components.
Arrange regular inspections of electronic control systems.
Arrange to regularly add lubricating grease to bolts and sealing components.
Regularly inspect the filter housing for paint peeling off..

Many industrial water filters need to be replaced within 18 months. Usually depends on the degree of pollution and frequency of use. Therefore, these factors will determine the service life of commercial water filters.
