Description

Dual static mixer for mixing fluids or gases The present invention relates to a static mixer, and more specifically, to a dual static mixer for fluid or gas mixing capable of maximizing the mixing efficiency and performance of the static mixer. Mixing in the general sense refers to a series of processes in which different heterogeneous substances are stirred to obtain a homogeneous mixture. For example, in the chemical industry, it is used in a wide variety of ways, ranging from simple mixing reactions to complex mixing reactions that can have a significant impact on mixing performance. In this case, a decrease in mixing efficiency can lead to a significant drop in the reaction rate below the required level, resulting in the forced termination of the reaction during the process; in particular, when approaching the lower critical point, the mixing efficiency may rapidly decrease due to the initiation of unnecessary reactions. Meanwhile, mechanical agitators are representative devices for mixing, and other examples include static mixers that are mounted and operated within pipes or ducts without moving or operating parts. For example, static mixers are installed in raw material transfer lines in factories to mix various raw materials, or installed in heat exchangers to increase heat exchange efficiency. These static mixers began to be developed in the 1950s, and since the mixer developed by Kenics began to be commercially used in the late 1960s, more than 30 types have been developed to date, but the number of static mixers actually used in industrial settings is very small. In addition, according to the static mixer developed by Kenics, when fluid moves along the internal flow path, turbulence is formed by the unit panel in the central part of the flow path, allowing for easy mixing of the fluid; however, a 'laminar flow phenomenon' occurs between the unit panel, where a fine gap is formed, and the inner surface of the housing. Since the fluid flow caused by this laminar flow phenomenon continues to move along the inner surface of the housing and is discharged to the outside of the housing, it ultimately acts as a cause that drastically impedes the overall mixing efficiency of the fluid.
