Silicone Oil Fiberglass Wool Fiber Bed Mist Eliminator Alkali Resistance

Chlor-Alkali Industrial Silicone Oil Fiberglass Wool Fiber Bed Mist Eliminator

Description of Fiber bed mist eliminator

Fiber mesh demisters (demisters) consist of a compressed fiber mat filled between two concentric screens or parallel flat screens. Depending on design parameters, these mist eliminators can collect up to 99.95% or more of sub-micron liquid particles. Fiber demisters are individually designed and manufactured for the customer, with housings made of various alloys, thermoformed plastics or fiberglass reinforced plastics. The materials used for the compressed fiber bed are special glass wool, ceramics, polypropylene, PTFE or polyester fibers. Mist eliminators of this type have proven to be very suitable for sulfuric acid plants, nitric acid plants and thermal phosphoric acid plants, chlorine and other chemical plants, pulp plants, textile plants, asphalt saturation towers, food processing, chroming processes, turbine lube oil tank exhaust Tube and plastic molding. Applications containing fluoride, high pH or steam can use special carbon fibers.

According to the capture mechanism of the fiber demister, the fiber mesh demister (demister) is divided into a low-speed fiber mesh demister (demister) and a high-speed fiber mesh demister (demist). .

Scope of application of fiber Mist Eliminators (demister)

· Fiber mesh demister (demister) Used after the drying tower in sulfuric acid production or after the first suction tower and the final absorption tower in the two-turn and two-suction process, it can effectively protect the fan and heat exchanger and prevent catalyst poisoning , to ensure balanced production, prevent air pollution, and protect the environment.

· Fiber mesh demister (demister) capture of phosphoric acid mist in phosphoric acid production, and tail gas nitric acid mist in nitric acid production.

· Fiber mesh demister (demister) Capture of sulfuric acid mist in the production of methyl disulfide, and capture of hydrochloric acid mist in the production of chlorosulfonic acid.

· Fiber mesh demister (demister) Dewatering of wet chlorine gas in chlor-alkali production and removal of water in sulfuric acid mist and hydrogen carried by sulfuric acid drying after dewatering.

Fiber mesh demister (demister) Distillation in petrochemical industry, gas-liquid separation in synthetic ammonia industry, acid mist in hydrochloric acid production, etc., can use fiber mesh demister (demister) to solve the problems in production. Practical problems.

Fiber Bed Mist Eliminators Specifications

Low-Velocity Fiber-Bed Mist Eliminators ME FGM type

Low-velocity mist eliminators are optimally equipped with a mix of glass fiber and a specific proportion of coarse and fine fibers. Coarse resistant fibers ensure uniform distribution of finer ones, increase the velocity of liquid discharge out of layer, giving the latter the mechanical strength and stability, and ensuring the operation of finer fibers throughout the layer. Usually the layers made of fibers 5-20 mcm in diameter and 88-92 % porosity are used . More often, the fibers 8 to 15 mcm in diameter with 50-60 mm layer thickness are used.

The basic material we use in filtering part is a special chemically-stable fiber glass FGM 145 in the form of multilayer needle-punched fabric resistant to concentrated and diluted acids. Besides, synthetic fibers of other types may be used depending on operating environment.

Hydraulic resistance: not more than 150 mm of water column.

Efficiency of mist eliminator of this type may be decreased in case the operating gas flow contains insoluble organic, metallic or mineral particles which may penetrate into the mist eliminator from the units installed before it. These may also be sulfate particles or chemically generated salts such as ammonium sulfate, ammonium nitrate, nitrosilic-sulfuric anhydride, nitrosilic pyrosulfite, etc.;

- in case the operating gas flow contains any amounts of HF or PH alkaline which cause the corrosion of fiber glass and may destroy the filtering part.

- in case the gas flow velocity is higher than 0.2 m/sec.

- in case the gas humidity is insignificant. The filtering part is efficient in humid state, and, in addition to the fiber thickness, the moisture creates “additional resistance” and Browning diffusion effect.
