Raschig ring

Ceramic lacey ring

Ceramic raschig ring is a kind of bulk packing developed earlier. The shape is simple. It is a ring of equal height and diameter. Largish ring (more than 100mm) is usually filled in a regular way, while the ring below 100mm is usually filled in a random way. Ceramic raschig ring packing can excellent acid and alkali resistant, except hydrofluoric acid of various inorganic acid, organic acid and alkali and organic solvent corrosion, available in a variety of high temperature, low temperature applications, application range is very wide, used in chemical industry, metallurgy, coal gas, acid, etc of the drying tower, absorption tower, cooling tower, regeneration tower and so on.

Product description:

Laissez ring has excellent acid resistance and heat resistance, and can resist the corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid.

The basic information

Rasching ring is an artificial filler that has been used in industry for a long time. Usually made of ceramic or metal sheet, plastic, its height is equal to the diameter, the commonly used size is 25mm~75mm (also have small to 6mm, large to 150mm). The thickness of the ceramic wall is 2.5mm~9.5mm, and the metal ring is 0.8mm~1.6mm. The wall of the ring should be thinned as far as the strength permits. Although the mass transfer performance is not ideal, but due to the simple structure, easy to manufacture, the price is lower, still for some factories to use.

Rasch ring material

Plastic rasping ring

Plastic lacy ring is made of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyvinylidene chloride (PVDF), chlorinated polyvinyl chloride (CPVC), reinforced polypropylene (RPP) and so on!

Lacey ring metal lacey ring

Metal rasping ring filler material can be a variety of, such as carbon steel, stainless steel 304, 304L, 410, 316, 316L, etc., available for choice.

Ceramic lassie ring plastic lassie ring is a ring packing with fixed geometric shape. The characteristic of lassie ring is that the outer diameter and height of the packing ring are equal

Ceramic raschig ring is a kind of bulk packing developed very early. The shape is simple. It is a ring of equal height and diameter. Largish ring (more than 100mm) is usually filled in a regular way, while the ring below 100mm is usually filled in a random way. As raschig ring filler opening rate is high, the space is large, large flux, small resistance, which makes the gas and liquid packing tower through freely, gas and liquid distribution in packing layer is relatively good, especially in the packing ring surface easy to liquid wetting, regardless of its location on the liquid on the packing, some flow along the outer wall, some flow along the wall. In this way, the liquid dispersion increases and the utilization rate of the inner surface of the packing increases. Therefore, it not only has a large passing capacity and a low pressure drop, but also has a high mass transfer separation efficiency.

Ceramic raschig ring packing can excellent acid and alkali resistant, except hydrofluoric acid of various inorganic acid, organic acid and alkali and organic solvent corrosion, available in a variety of high temperature, low temperature applications, application range is very wide, used in chemical industry, metallurgy, coal gas, acid, etc of the drying tower, absorption tower, cooling tower, regeneration tower and so on.
