Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical equipment packing, particularly relates to a high-strength stainless steel metal rectangular saddle ring. BACKGROUND

[0002] In many industrial processes such as chemical production and petroleum refining, tower equipment is an important equipment for realizing gas-liquid mass transfer and heat transfer, and tower packing is one of the core components of the tower equipment. Traditional tower packing, such as Raschig ring and Pall ring, has certain limitations in actual application.

[0003] 1. The uneven distribution of gas and liquid caused by the structural design of traditional packing, insufficient contact between gas and liquid in some areas, makes it difficult to further improve the mass transfer efficiency, limits the separation effect and production capacity of the tower equipment. For example, when the Raschig ring is filled in the tower, liquid deflection and wall flow phenomenon easily occur, which reduces the gas-liquid mass transfer efficiency; 2. In some high-pressure, high-temperature or strong corrosion working environment, the strength of the traditional packing is insufficient, which is easy to deform and damage, affecting the normal operation and service life of the equipment. Moreover, its stability is poor, and under the impact of gas and liquid flow, the packing layer may be loose and collapsed, which further leads to unstable working conditions in the tower. SUMMARY

[0004] The main purpose of the utility model is to provide a high-strength stainless steel metal rectangular saddle ring, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is:

[0013] Preferably, the plurality of insertion holes are circular, and the plurality of insertion holes on the second reinforcing rib piece are arrayed.

[0014] By adopting the technical scheme, the plurality of insertion holes are circular and arrayed on the second reinforcing rib piece, which facilitates the smooth insertion of rivets, reduces installation resistance, and ensures connection accuracy. The arrayed distribution can ensure that the second reinforcing rib piece is stably connected to the trapezoidal saddle-shaped main body, making the overall structure bear force uniformly and improving the strength and stability of the metal trapezoidal saddle ring.

[0015] Preferably, the height-to-width ratio of the trapezoidal saddle-shaped main body is 1:1.2-1:1.5.

[0016] By adopting the technical scheme, the height-to-width ratio of the trapezoidal saddle-shaped main body is 1:1.2-1:1.5, which optimizes the spatial layout of the trapezoidal saddle-shaped main body in the tower. It can ensure that gas and liquid have sufficient contact area for mass and heat transfer, and also ensure smooth gas-liquid flow, reduce flow resistance, and improve the operating efficiency and separation performance of the tower equipment.
