Metal Pall Ring

Product description

The Pall ring is developed on the basis of the Raschig ring. It is made of stamped metal sheets. Two rows of windows with inwardly extending tongues are opened on the ring wall. Each row of windows has five tongue bends. Enter the ring, point to the center of the ring, and almost overlap at the center. The positions of the upper and lower windows are staggered from each other. Generally, the total area of the openings is about 35% of the entire ring area. This structure better improves the packing. The distribution of gas and liquid in the layer makes full use of the inner surface of the ring so that the gas and liquid in the packed tower can pass freely through the window. Its mass transfer performance is greatly improved compared to the Raschig ring. It is one of the main ring-shaped packings used.

Material and size

Size: 6mm, 10mm, 13mm, 16mm, 25mm, 38mm, 50mm, 76mm, 89mm, etc.

Material: stainless steel, carbon steel, copper, aluminum, etc. Stainless steel includes 304, 304L, 316, 316L, 410, etc.

Characteristics

(1) High mass transfer efficiency

It has a unique structure and a ring-shaped appearance. Two rows of windows with inwardly extending tongues are opened on the ring wall. Each row of windows has five tongues bent into the ring, pointing towards the center of the ring. The unique structure makes the mass transfer efficiency of metal Pall rings much higher than that of ordinary packing. Usually, when the flow rate and pressure are the same, the mass transfer efficiency can be increased by more than 50%.

(2) Good liquid distribution characteristics

The design of the metal Pall ring enables it to distribute liquid well in the reactor or distillation tower, and there are many small holes inside the metal Pall ring so that the liquid can flow freely, which improves the distribution performance of the fluid to some extent. .

(3) Strong resistance to high temperature and high pressure

Metal Pall rings are made of high-quality metal materials and have high mechanical strength and corrosion resistance. 4. Easy to clean and maintain

There is almost no fluid accumulation inside the metal Pall Ring, and it is very convenient to clean and maintain. In addition, metal Pall rings have a long service life and can be reused many times, which has high economic benefits.

Application

Metal Pall rings are suitable for various separation, absorption, desorption devices, atmospheric and vacuum devices, synthetic ammonia decarbonization, desulfurization systems, ethylbenzene separation, isooctane, toluene separation, etc.

Our company sells large quantities of metal Pall rings to various countries every month. Whether it is product quality, price and service, customers have praised it. The following are pictures of the Pall rings we produce:
