Abstract
The utility model relates to a double-layer stainless steel made corrugated wire gauze packing composed of a plurality of corrugated plates compacted by double layer stainless steel cloth and a stainless steel cloth housing. A plurality of double layer stainless steel cloth corrugated plates are vertically arranged in the stainless steel cloth housing. The corrugated directions of the two contiguous corrugated plates are opposite. The double layer stainless steel cloth corrugated plates are sloping corrugated plates. The peak line or the valley line of the corrugated plate forms an inclination angle with the normal axis of the packing disc. The double layer stainless steel cloth corrugated plate are provided with a plurality of small holes. A gas passage formed by the packing is flexural in the east, south, west and north. The gas passage spirally rotates at the front, back, left and right. The exciting force of the gas and the contact time of the gas are increased to accelerate the improvement of the column efficiency.
Description
Technical field
The utility model relates to industrial tower high efficiency packing technical field, relates in particular to a kind of double-layer stainless steel screen waviness packings that is applied in nitrogen-15 process units.
Background technology
At present, the process units of nitrogen-15 all is to adopt stainless steel wire spiral coil high-efficient granule filler, this filler at tower diameter hour, its theoretical plate equivalent altitude HETP value is very little, if tower diameter is amplified to 100mm when above, the then rapid rising of HETP value.For example former German Democratic Republic Waller sweet smell (Warlfen)
15The N process units, when tower diameter is 27mm, HETP=5cm, when tower diameter is amplified to 200mm, HETP=20cm, decrease in efficiency 4 times.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of tower diameter that makes still can keep high efficiency double-layer stainless steel screen waviness packings under the situation of amplifying for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: the double-layer stainless steel screen waviness packings, it is characterized in that, this filler comprises corrugated plate and the stainless steel cloth housing that multi-disc is formed by the compacting of double-layer stainless steel silk screen, described multi-disc double-layer stainless steel screen waviness sheet arranged vertical is in above-mentioned stainless steel cloth housing, and the ripple direction of adjacent two corrugated plates is opposite, described double-layer stainless steel screen waviness sheet is the inclination corrugated plate, the crest line of this corrugated plate or valley line and packing box vertical axis have an inclination angle, and described double-layer stainless steel screen waviness sheet is provided with a plurality of apertures.
Peak height h=2.5～the 4mm of the double-layer stainless steel screen waviness sheet of described arranged vertical, pitch of waves 2B=4～7mm, the ripple inclination angle is 30 °～60 °.
Described ripple inclination angle is 45 °.
Described double-layer stainless steel silk screen is 60～100 orders, and double-layer stainless steel screen waviness sheet aperture is 2mm, pitch-row 8～10mm, and be triangularly arranged.
Described double-layer stainless steel screen waviness packings is cylindrical, and its external diameter and tower diameter are suitable, the high 40～100mm of filler.
Described cylindrical double-layer stainless steel screen waviness packings look tower height can install a plurality of, the 90 ° of installations that interlace each other of the corrugated plate direction of adjacent two fillers.
The surface area of the exchange mutually α＞1000m of described double-layer stainless steel screen waviness packings

The utility model is applied in NO-HNO
3In the system, through the industrial condition examination, diameter is the stainless steel exchange column of 150mm, its theoretical plate equivalent altitude HETP=12cm, and the diameter of former German Democratic Republic Waller sweet smell (Warlfen) factory is the identical of 150mm
15N process units HETP=15cm, both differ 20% at efficient.
No matter still external at home, in nitrogen-15 process units, still there is not the precedent of using general stainless steel wire corrugated wire gauze packing, letting alone has been the double-layer stainless steel screen waviness packings.Corrugated wire gauze packing has that its flux is big, characteristics such as little, that efficient is high (plate column and general packed tower relatively), enlarge-effect is not obvious fall in pressure, and double-deck screen waviness packings efficient is just higher.
