Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of filler, especially a zigzag double-layer metal wire mesh corrugated filler. BACKGROUND

[0002] The structured filler plays an important role as the main component of gas-liquid contact in the filler tower. In recent years, with the development of petroleum chemical industry and the need of energy saving, the development and application of structured filler have developed rapidly, and the breakthrough changes in distillation and absorption and other chemical fields also promote the research and development of high-flux structured filler.

[0003] In the separation process such as rectification and absorption in chemical industry, petroleum and other industries, the traditional metal wire mesh corrugated filler structure is relatively single, and the gas-liquid contact area is limited. The common single-layer plane structure filler is that the gas-liquid mixing is not sufficient when the fluid flows in it, which leads to that the mass transfer efficiency is difficult to meet the increasing production demand, limits the production capacity improvement and product quality optimization of equipment, in addition, the previous filler installation method is complex, and the integral structure is often used, professional tools and a large amount of manpower are needed during installation, and a long time is consumed. When the equipment is overhauled and maintained, if the filler has problems, it is difficult to disassemble and replace quickly, which affects the normal operation time of the equipment and increases the operation cost of the enterprise, therefore, we launch a zigzag double-layer metal wire mesh corrugated filler.
