CN201823532U - Pall ring - Google Patents

Abstract

The utility model discloses a Pall ring, comprising a cylindrical body; the body is provided with a plurality of windows which are uniformly distributed along the circumferential direction of the body; and the side edge of each window is provided with tongue pieces. The Pall ring is characterized in that two axially-adjacent tongue pieces are arranged in an intersecting manner. By adopting the technical scheme, not only the Pall ring is wear-resistant, but also the inner surface of the Pall ring is easy to be wetted by liquid; and simultaneously, as the windows are added, the resistance in a tower can be reduced, so that the surface is not easily stuck with scales.

Description

A kind of Pall ring

Technical field

The utility model relates to a kind of filler in the chemical field, specifically relates to a kind of Pall ring.

Background technology

Packed tower is one of the most frequently used gas-liquid mass transfer (contact) equipment, is widely used in rectifying, absorb, and extraction, heat exchange etc. separate in the engineering.Because chemical gases and liquid are under manufacture process requirement, in tower, require to do the order walking, and require to exchange abundant more well more, and the tower internal resistance does not allow too high, adds filler in void tower, and the chemical industry air-flow is fully contacted with liquid stream, to reach the purpose of abundant exchange, exchange fully more, render a service just highly more, but require the resistance deficiency of tower too high.

Pall ring is exactly a kind of version in the tower filler, it is the ring-like filler of perforate that a kind of high footpath equates, because the Pall ring filler has been opened many fenestras on ring wall, make gas and liquid in the packed tower freely to pass through from fenestra, so gas and liquid distribution situation in the packing layer have greatly improved than Raschig ring, especially the packing ring inner surface is wetting by liquid easily, makes inner surface be fully utilized.At present, the Pall ring of use has following shortcoming: 1, easy to wear, service life is short; 2, inner surface is difficult for moistening by liquid; 3, sticking incrustation is stained with on the surface easily.

The utility model content

Problem to be solved in the utility model provides a kind of not easy to wear, easily moistening and surperficial Pall ring that is difficult for being stained with sticking incrustation of inner surface.

For addressing the above problem, the technical scheme that the utility model adopted is:

A kind of Pall ring comprises columniform body, and described body is provided with several windows, and described window is circumferentially uniform along body, and the side of each window is characterized in that along being provided with tongue piece: described two adjacent in the axial direction tongue pieces are arranged in a crossed manner.

As a kind of improvement:

Described tongue piece is a circular arc.

Dactylogryposis makes inner surface moistening by liquid easily to the center line of body in the tongue piece.

As further improvement:

Described window axially is provided with four layers along body.

Traditional window generally weares and teares easily along two-layer, the two-layer body that axially is provided with of body, and causes the tower internal resistance too big, and influence is produced.

The utility model is by adopting technique scheme, and Pall ring is not only wear-resisting, and inner surface is also easily moistening by liquid, simultaneously, because the increase of window can reduce the tower internal resistance, makes the surface be difficult for being stained with sticking incrustation.

Below in conjunction with accompanying drawing the utility model is further described.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model embodiment;

Accompanying drawing 2 is the vertical view of accompanying drawing 1.

Among the figure: the 1-body; The 2-window; The 3-tongue piece.

The specific embodiment

Embodiment: as depicted in figs. 1 and 2, a kind of Pall ring comprises columniform body 1, described body 1 is provided with several windows 2, and described window 2 is circumferentially uniform along body 1, and wherein window 2 axially is provided with four layers along body 1, every layer is five, has wear-resisting and reduces the effect of resistance.

The side of each window 2 is along being provided with tongue piece 3, and tongue piece 3 is a circular arc, and dactylogryposis are to the center line of body 1 in the tongue piece 3, and described two adjacent in the axial direction tongue pieces 3 are arranged in a crossed manner, is convenient to the wetting of inner surface and is difficult for being stained with on the surface sticking incrustation.

Claims (3)

1. Pall ring, comprise columniform body (1), described body (1) is provided with several windows (2), described window (2) is axially uniform along body (1), the side of each window (2) is characterized in that along being provided with tongue piece (3): described two adjacent in the axial direction tongue pieces (3) are arranged in a crossed manner.

2. a kind of Pall ring as claimed in claim 1 is characterized in that: described tongue piece (3) is a circular arc.

3. a kind of Pall ring as claimed in claim 1 or 2 is characterized in that: described window (2) axially is provided with four layers along body (1).
