Abstract
The invention relates to a double-layer cascade ring packing and belongs to the field of a petrochemical technology. The cascade ring packing is made from metal. The outer wall of the cascade ring packing has a circular shape from a looking-down perspective. First, second and third vanes are arranged respectively between first, second and third points which are 120 degrees spaced on the inner circumference of the outer wall. The inner circumference of the outer wall also has fourth, fifth and sixth points obtained by rotating the first, second and third points 60 degrees. Fourth, fifth and sixth vanes are arranged respectively between the fourth, fifth and sixth points. The first to sixth vanes all have an arc-shaped tongue piece raised towards the outer wall. The first to sixth vanes all have a gap corresponding to the respective tongue piece. The cascade ring packing provided by the invention has a staggered double-layer vanes structure and has good pressure resistance. As the vanes are separated by 120 degrees, gaps between packings are not enough to stack up mutually.
Description
Technical field
The present invention relates to a kind of Double-ladder ring filler, belong to technical field of petrochemical industry.
Background technology
Dumped packing is the critical piece in petrochemical industry; Its stuctures and properties has material impact to the disposal ability of packed tower, product quality and technical-economic index.Dumped packing, according to its shape difference, can be divided into the various ways such as Raschig ring, Pall ring, cascade ring, flat ring, conjugate ring and rectangular saddle ring.
In actual production, often there is mutual intussusception phenomenon between dumped packing, greatly affect production efficiency, reduce product quality.
Summary of the invention
The present invention wants technical solution problem to be: the shortcoming overcoming above-mentioned technology, provides a kind of Double-ladder ring filler reducing intussusception probability.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of Double-ladder ring filler, described ladder ring packing is made of metal, its outer wall is overlooked rounded, and the inner periphery of described outer wall has first, second, and third blade between first, second, and third of the 120 degree of circular arcs in interval; Described first blade connects described first and second points, and described second blade connects described second and thirdly, described Three-blade connection described first and thirdly; The inner periphery of described outer wall also has the 4th, the 5th and the 6th point being rotated 60 degree of gained at described first, second, and third; Described 4th, there is between the 5th and the 6th the 4th, the 5th and the 6th blade; Described quaterfoil connects the described 4th and the 5th point, and described 5th blade connects the described 5th and the 6th point; Described 6th blade connects the described 4th and the 6th point; Described first to the 6th blade is all in the arc towards described hexagon central protuberance; Described first is the half of described outer wall height to six-bladed height; Described first, second, and third blade is positioned at one end of described outer wall, forms the first ladder; Described 4th, the 5th and the 6th blade is positioned at the other end of described outer wall, forms the second ladder; Described first to the 6th blade all has towards the arc tongue piece of described outer wall projection; Described first to the 6th blade have the breach corresponding with described tongue piece.
Such scheme further improves and is: described outer wall offers window; Described window is two-layer, corresponding with the position of first, second ladder described respectively altogether.
Such scheme further improves and is: the upper and lower two ends of described outer wall have crimping.
Such scheme further improves and is: the height of described outer wall and equal diameters.
Double-ladder ring filler provided by the invention has interlaced twi-tier blade structure, there is good compressive property, its blades span 120 degree, the space between filler and filler is made to be not enough to mutual intussusception, further, have the effect that 6 blades play reinforcement altogether, strengthen outer wall intensity, higher pressure can be born, prevent the intussusception that breakage causes.Blade also has tongue piece, prevents damaged protrusion from going deep within outer wall further.Meanwhile, overall hole is comparatively large, and liquids and gases are less by pressure, and outer wall also offers window, are further decreased through pressure.

Detailed description of the invention
Embodiment
The Double-ladder ring filler that the present embodiment provides, as shown in Figure 1, this filler is made of metal, and its outer wall 1 is overlooked in circle,
On the inner periphery of outer wall 1,120 degree, interval circular arc has first, second, and third point; By first, second, and third rotate 60 degree to the 4th, the 5th and the 6th point; First blade 2 connects the first and second points, and the second blade 6 connects second and thirdly, and Three-blade 5 connects first and thirdly; Quaterfoil 4 connects the 4th and the 5th point, and the 5th blade 3 connects the 5th and the 6th point; 6th blade 7 connects the 4th and the 6th point; First to the 6th blade is all in the arc towards hexagon central protuberance; First is the half of outer wall height to six-bladed height; First, second, and third blade is positioned at one end of outer wall, forms the first ladder; Four, the 5th and the 6th blade is positioned at the other end of outer wall, forms the second ladder; First to the 6th blade all has towards the arc tongue piece of outer wall projection; First to the 6th blade have the breach corresponding with tongue piece.
As shown in Figure 2, outer wall 1 offers window; Window is altogether two-layer, offers position corresponding with first, second ladder, like this can more effective increase flow, reduction pressure; Outer wall about 1 two ends have bead structure to gain in strength; The height of outer wall 1 and equal diameters, make its side view in square, can more effective renitency, prevents breakage.
The present invention is not limited to the concrete technical scheme described in above-described embodiment, and in addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacing and being formed, and are the protection domain of application claims.
