　　CY700 type wire mesh corrugated packing metal 304 wire mesh corrugated packing distillation tower packing

　　1) Product Description:

　　The wire mesh corrugated packing produced by Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province is composed of wire mesh sheets arranged in a corrugated manner, with a corrugated sheet inclination angle of 30 degrees or 45 degrees; Adjacent corrugated sheets have opposite directions, and when filling inside the tower, the upper and lower packing plates are staggered and stacked at a 90 degree angle. It has the advantages of high efficiency, pressure reduction, and high flux. The products include BX and CY types, which are commonly used in vacuum distillation, atmospheric distillation, and absorption processes for difficult to separate and thermosensitive substances;

　　4) CY700 Wire Mesh Ripple Introduction:

　　CY700 metal wire mesh corrugated filler is a new type of water purification material widely used in the field of water treatment. The standard material is arranged in a certain geometric configuration and neatly stacked. There are many types of structured materials, which can be divided into grid materials, corrugated fillers, etc. based on their geometric structure. Corrugated materials can be divided into two categories based on their structure: mesh corrugated materials and plate corrugated fillers, with materials such as metal, plastic, and ceramic. The vast majority of regular packing materials used in industry are corrugated materials, which are disc-shaped packing composed of many corrugated sheets. The corrugated sheets have two angles of inclination with the tower axis, 30 ° and 45 °, and are assembled in opposite directions with two corrugated sheets. Each tray of material is vertically loaded into the tower, with adjacent trays of packing arranged in a 90 degree staggered manner.

　　The characteristics of CY700 metal wire mesh corrugated filler are high theoretical plate number, high flux, and reduced pressure; Good low load performance, the theoretical number of plates increases with the decrease of gas load, and there is almost no low load limit; High operational flexibility, with insignificant amplification effect; Can meet the requirements of precision, large, and high vacuum distillation equipment. The materials here include stainless steel, brass, phosphor copper, low-carbon steel, etc., which are widely used in the distillation separation of difficult to separate systems, thermosensitive systems, and high-purity products. When installing carbon steel black wire mesh regular packing CY700 metal wire mesh corrugated packing, the tower is usually laid down horizontally, and the wire mesh packing is placed inside the tower. A long flat plate is used to push it to the bottom, and each layer of packing is installed at a certain angle, usually 45 degrees. For large towers, multiple pieces are separated and assembled inside the tower. The packing is installed vertically on the tower, as close to the wall as possible, and the gaps between the packing are filled with fragments. Similarly, the angles between each layer should also be staggered.

　　Introduction to Performance Comparison of Metal Wire Mesh Corrugated Filler Product Models:

　　1) AX250 wire mesh corrugated packing is mainly used for high production capacity and operating pressure generally between 102-106Pa;

　　2) BX500 metal wire mesh corrugated packing is suitable for vacuum distillation of thermosensitive and difficult to separate systems, especially under conditions below 7Kpa. Mainly used in petrochemical and general chemical industries: such as the successful use of 500 type metal wire mesh corrugated packing tower separation in formaldehyde refining units, with product purity greater than 99% 9%, impurity content less than 300ppm, increased production capacity and reduced energy consumption; The vacuum distillation unit for dimethyl terephthalate has been successfully put into operation using 500 type packing, and has achieved good results for the past 20 years; Purification and refinement of vitamin E: Vitamin E is a thermosensitive substance, and due to its high efficiency and low pressure drop characteristics, the wire mesh corrugated packing can refine vitamin E in the form of ordinary vacuum distillation in a packed tower. A pharmaceutical factory in China has introduced a distillation device and technology for producing vitamin E from Swiss company Sulzer. The distillation tower uses BX500 metal wire mesh corrugated, with a packing layer height of 2.04 meters, a top pressure of 50 Pa, a bottom pressure of no more than 200 Pa, and a kettle temperature of no more than 250 ℃. The yield of vitamin C is over 90%, and the purity can reach over 99.5%.

　　3) CY700 metal wire mesh corrugations are generally used for precise fractionation of isotopes or difficult to separate systems that require a large number of theoretical plates. These system separations require hundreds of theoretical plates. It is also commonly used in situations where high purity products are required or highly restricted, and is mainly used in many petrochemical, spice, pharmaceutical, and dye products. Its operating pressure range is not only 5-100kPa, but has also expanded to the fields of pressurization and low-temperature distillation. For the separation of synthetic fatty acids, a 700Y type metal wire mesh corrugated packing tower is used for vacuum distillation, and the purity of monocarbonate can reach 92-98%.
