Abstract
The device is an improved pall ring and is mainly characterized by comprising a multi-arc-shaped cylinder body and a central support structure, the arc-ball type pall ring has large specific surface area and porosity and high strength, and the filler for manufacturing unit volume is less than the material consumed by the pall ring. The filler has excellent performance and simple manufacture, and can be used for heat transfer and mass transfer equipment in a chemical process. Has high production value.
Description
A kind of filler belongs to the engineering element of chemical process.
At present, packed tower is widely applied in the mass transfer separation process of chemical industry both at home and abroad, and its filling kind is a lot, and common fillers wherein commonly used is a Pall ring, and it is a cylinder and has the arc sheet that forms to the center punching press from cylinder.Shortcoming such as Pall ring still exists specific area and voidage is lower, rigidity and intensity are relatively poor.
Goal of the invention of the present utility model just is to provide a kind of follow-on Pall ring to improve its serviceability and to overcome above-mentioned shortcoming.
The utility model takes following design to realize above-mentioned purpose:
Be provided with a centerbody ［ 3 ］ at the filler center that is made of cylindrical shell ［ 1 ］ and arc sheet ［ 2 ］, this centerbody can be made into spheroid, adopts pillar ［ 4 ］ connection between centerbody ［ 3 ］ and the cylindrical shell ［ 1 ］, and this pillar can be for three or more than three cylinder.The multi sphere shape similar round that the cross sectional shape of cylindrical shell ［ 1 ］ is made up of the arc of many less radius of curvature R 1, middle arc sheet is actual to be that a part of punching out of cylindrical shell forms.
The utility model is compared with Pall ring has tangible advantage and good effect, owing to adopted the cylindrical shell of multi sphere shape and be provided with the structure that centerbody adds pillar, thereby specific area and voidage are improved greatly, and strength and stiffness have been increased again, also played the effect of linking up liquid phase in addition, made and do not produce bias current in the tower.
Promptly instantiation of the present utility model shown in the accompanying drawing.Fig. 1 is the front view of utility model, and Fig. 2 is the A-A cutaway view of Fig. 1.Among the figure: 1, cylindrical shell 2, arc sheet 3, centerbody 4, pillar
Its concrete structure is very similar to Pall ring, and its manufacturing process also can adopt the preparation method of Pall ring fully, and different is that heart position is provided with a spheroid therein, goes out three cylindrical columns and multi sphere shape cylindrical shell links by this spherical radiation.Owing to be provided with central support structure, thereby the comparable Pall ring of the thickness of cylindrical shell is thin, thereby material consumption is reduced.
Claims (3)
1, a kind of arc ball Pall ring belongs to the engineering element of chemical engineering, by cylindrical shell [1] and arc sheet formations such as [2].The invention is characterized in to have arc sheet [2], centerbody [3] and pillar [4].
2, as the arc ball Pall ring as described in claims 1, the cross sectional shape that it is characterized in that said cylindrical shell ［ 1 ］ by many than small curvature radius ［ R1 ］ arc and the multi sphere shape similar round formed; Said arc sheet ［ 2 ］ is that a part of punching out by cylindrical shell forms.
3, arc ball Pall ring according to claim 1 is characterized in that said centerbody ［ 3 ］ is a spheroid; Said pillar ［ 4 ］ is three or more than three cylinder, and these pillars connect cylindrical shell and center to be reinforced.
