Problems solved by technology

However, the structure of the baffle rod support ring is manufactured by riveting and welding, and the manufacturing deviation is large, which makes it difficult to assemble the tube bundle. At the same time, the baffle rod has a long span, few support points, poor rigidity, and is prone to vibration, which cannot achieve effective support.

Embodiment

[0022] Example: Combine figure 1 , 2 , the grid-type supporting baffle device of the shell-and-tube heat exchanger of this embodiment, which includes: a support limiting ring 1 welded and fixed to the inner wall of the heat exchanger shell 4, and a plurality of grids are arranged in the supporting limiting ring 1 The grid plates 2 are cross-connected to form a porous grid network. The heat exchange tubes 3 pass through the holes of the grid network and the outer walls of the heat exchange tubes 3 are in close contact with the inner walls of the holes. The two ends of each grid plate 2 are bounded by the support. The inner wall of the ring 1 is fixed by welding. The holes are rhombus holes or square holes.

[0023] In specific settings, figure 2 As shown, each grid plate 2 is provided with open slots 5, and any two intersecting grid plates are plugged into each other through the slots and the intersection points are welded and fixed. The center-to-center distance L between...

Abstract

The invention discloses a grid type supporting baffling device of a shell-and-tube heat exchanger, which comprises supporting limiting rings fixedly connected with the inner wall of a heat exchanger shell. A plurality of grid plates are connected in a crossed manner in each supporting limiting ring to form a porous grid, heat exchange tubes penetrate through holes of each grid, outer walls of the heat exchange tubes closely contact with inner walls of the holes, and two ends of each grid plate are fixedly connected with the inner wall of the corresponding supporting limiting ring. By the aid of the grid type supporting baffle device, heat transfer efficiency can be effectively improved, resistance loss of a shell pass is reduced, vibration of the heat exchange tubes is avoided, and the service life of equipment is prolonged.

Description

Technical field: [0001] The invention relates to a grid-type supporting baffle device for a shell-and-tube heat exchanger, which is suitable for the structure of shell-and-tube heat exchangers in industries such as petroleum, chemical industry, power, atomic energy, and metallurgy, and is mainly used for shell-and-tube heat exchange The support of the heat exchange tube of the heat exchanger and the disturbance of the shell-side fluid of the heat exchanger are enhanced. Background technique: [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers are common equipment in chemical, petroleum, military, steel and many other industrial installations, and play an important role in production. In order to improve the heat transfer efficiency of equipment, people have conducted extensive and in-depth research on heat exchange tubes, and various high-efficiency heat transfer tubes have bee...
