Novel multi-sleeve integrated rapid demounting and mounting heat exchanger

Abstract

The invention discloses a novel multi-sleeve integrated rapid demounting and mounting heat exchanger. The novel multi-sleeve integrated rapid demounting and mounting heat exchanger is mainly composedof inner tube passes, outer tube passes, inner tube boxes, outer tube boxes, packing box sealing structures, outer tube positioning plates and supporting seats. Fins are arranged on the outer walls ofthe inner tube passes to serve as movable supports. The outer tube passes and outer tube box tube plates are fixed in a welded mode. The inner tube boxes and inner tube plates are connected through flanges. The outer tube boxes and the inner tube boxes are connected through flanges. The inner tube passes are sealed on the inner tube plates through the packing box structures. Packing boxes and thetube plates are fixed in a welded mode, and packing seals are compressed by glands. The inner tube passes can move, and the glands are provided with positioning stop blocks to limit the moving rangeof the inner tubes. In this way, the novel multi-tube-pass rapid demounting and mounting sleeve heat exchanger which is compact in structure and convenient to demount and mount is formed. The problemsthat blockage is prone to occurring during heat transferring of a solid-containing fluid; direct heat exchanging of a medium is difficult, and the heat exchange efficiency is low; leakage is prone tooccurring; demounting, mounting and overhauling are difficult, and the maintenance cost is high; and cleaning is difficult are solved while the novel multi-sleeve integrated rapid demounting and mounting heat exchanger has the high heat transferring coefficient.

Description

technical field [0001] The invention relates to a novel casing heat exchanger. Especially a heat exchanger involving heat transfer in the fields of chemical industry, environmental protection, metallurgy, energy and food. Especially in heat exchange applications in preheating and heat recovery of media with high viscosity, solid particles, poor fluidity, and easy to block. 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 play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . [0003] Currently commonly used heat exchangers are: tubular heat exchangers (immersion heat exchangers, spray heat exchangers, casing heat exchangers, tube heat exchangers), plate heat exchangers (ja...

AI Technical Summary

Problems solved by technology

[0008] 1. It is difficult to overhaul, clean and disassemble, and it is easy to cause leakage at the detachable connection

[0009] 2. Most of the sleeve-type heat exchangers are not allowed to weld in the inner tube, because welding will cause thermal expansion and cracking, while most of the sleeve-type heat exchangers are bent and coiled into a serpentine shape in order to save space, so There are many special corrosion-resistant materials that cannot be produced normally

[0010] 3. The floor area is large, and the metal consumption per unit heat transfer area is large
