Description
技术领域technical field
本实用新型涉及工业塔器高效填料技术领域，尤其涉及一种应用于氮-15生产装置中的双层不锈钢丝网波纹填料。The utility model relates to the technical field of high-efficiency packing for industrial towers, in particular to a double-layer stainless steel wire mesh corrugated packing used in a nitrogen-15 production device.
背景技术Background technique
目前，氮-15的生产装置都是采用不锈钢丝螺旋圈高效颗粒填料，该填料在塔径较小时，其理论板当量高度HETP值很小，若塔径放大到100mm以上时，则HETP值急剧上升。例如原民主德国沃勒芬(Warlfen)15N生产装置，塔径为27mm时，HETP＝5cm，当塔径放大至200mm时，HETP＝20cm，效率下降了4倍。At present, the nitrogen-15 production equipment is all using stainless steel wire helical high-efficiency particle packing. When the tower diameter is small, the theoretical plate equivalent height HETP value is very small. If the tower diameter is enlarged to more than 100mm, the HETP value will be sharp. rise. For example, in the original Warlfen 15 N production plant in the Democratic Republic of Germany, when the tower diameter is 27mm, HETP=5cm, when the tower diameter is enlarged to 200mm, HETP=20cm, and the efficiency drops by 4 times.
发明内容Contents of the invention
本发明的目的就是为了克服上述现有技术存在的缺陷而提供一种可使塔径在放大的情况下仍能保持高效率的双层不锈钢丝网波纹填料。The object of the present invention is to provide a double-layer stainless steel wire mesh corrugated packing that can maintain high efficiency even when the tower diameter is enlarged in order to overcome the above-mentioned defects in the prior art.
本发明的目的可以通过以下技术方案来实现：双层不锈钢丝网波纹填料，其特征在于，该填料包括多片由双层不锈钢丝网压制而成的波纹片和不锈钢丝网外框，所述的多片双层不锈钢丝网波纹片垂直排列在上述不锈钢丝网外框内，且相邻两波纹片的波纹方向相反，所述的双层不锈钢丝网波纹片为倾斜波纹片，该波纹片的峰线或谷线与填料盘垂直轴线有一倾角，所述的双层不锈钢丝网波纹片上设有多个小孔。The purpose of the present invention can be achieved through the following technical solutions: double-layer stainless steel wire mesh corrugated packing, which is characterized in that the packing includes a plurality of corrugated sheets pressed by double-layer stainless steel wire mesh and a stainless steel wire mesh outer frame. A plurality of double-layer stainless steel wire mesh corrugated sheets are vertically arranged in the above-mentioned stainless steel wire mesh outer frame, and the corrugated directions of two adjacent corrugated sheets are opposite. The double-layer stainless steel wire mesh corrugated sheets are inclined corrugated sheets, and the corrugated sheets There is an inclination angle between the peak line or valley line and the vertical axis of the packing disc, and a plurality of small holes are arranged on the double-layer stainless steel wire mesh corrugated sheet.
所述的垂直排列的双层不锈钢丝网波纹片的峰高h＝2.5～4mm，波距2B＝4～7mm，波纹倾角为30°～60°。The vertically arranged double-layer stainless steel wire mesh corrugated sheet has a peak height h=2.5-4mm, a wave pitch 2B=4-7mm, and a corrugation inclination angle of 30°-60°.
所述的波纹倾角为45°。The inclination angle of the corrugation is 45°.
所述的双层不锈钢丝网为60～100目，双层不锈钢丝网波纹片小孔为2mm，孔距8～10mm，且呈三角形排列。The double-layer stainless steel wire mesh is 60-100 mesh, the small holes of the corrugated sheet of the double-layer stainless steel wire mesh are 2mm, and the hole distance is 8-10mm, and they are arranged in a triangle.
所述的双层不锈钢丝网波纹填料呈圆柱形，其外径与塔径相当，填料高40～100mm。The double-layer stainless steel wire mesh corrugated packing is cylindrical, its outer diameter is equivalent to the tower diameter, and the packing height is 40-100 mm.
所述的圆柱形双层不锈钢丝网波纹填料视塔高可安装多个，相邻两个填料的波纹片方向彼此相错90°安装。A plurality of cylindrical double-layer stainless steel wire mesh corrugated fillers can be installed depending on the height of the tower, and the directions of the corrugated sheets of two adjacent fillers are staggered by 90°.
所述的双层不锈钢丝网波纹填料的相交换表面积α＞1000m2/m3。The phase exchange surface area of the double-layer stainless steel wire mesh corrugated packing is α>1000m 2 /m 3 .
本实用新型应用在NO-HNO3体系中，经工业条件考查，直径为150mm的不锈钢交换塔，其理论板当量高度HETP＝12cm，而原民主德国沃勒芬(Warlfen)工厂的直径为150mm的相同15N生产装置HETP＝15cm，两者效率相差20％。The utility model is applied in the NO- HNO3 system. According to the investigation of industrial conditions, the stainless steel exchange tower with a diameter of 150mm has a theoretical plate equivalent height HETP=12cm, while the diameter of the former Warlfen (Warlfen) factory in Democratic Germany is 150mm. The same 15 N production device HETP=15cm, the efficiency difference between the two is 20%.
无论在国内还是国外，在氮-15生产装置中，尚无应用一般不锈钢丝网波纹填料的先例，更不要说是双层不锈钢丝网波纹填料了。金属丝网波纹填料有其通量大、压力降小、效率高(相对板式塔和一般填料塔而言)、放大效应不明显等特点，双层丝网波纹填料效率就更高了。Whether at home or abroad, there is no precedent for applying general stainless steel wire mesh corrugated packing in nitrogen-15 production equipment, let alone double-layer stainless steel wire mesh corrugated packing. Metal wire mesh corrugated packing has the characteristics of large flux, small pressure drop, high efficiency (compared to plate tower and general packed tower), and insignificant amplification effect. The efficiency of double-layer wire mesh corrugated packing is even higher.
