Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. In order to ensure that the tube holes of the tube sheet and the multi-piece spiral baffles are concentric, first, a plurality of heat exchange tubes are temporarily penetrated through the tube sheet and the multi-piece baffles to play a limiting role, and then the space between the spiral baffles , The spiral folded willow plate and the tube sheet are firmly fixed, and the temporary heat exchange tube can be taken out or not taken out, the baffle fixing assembly fixes the spiral baffle and the tube sheet to the holes,, the baffle fixing assembly The combination structure of traditional tie rods and spacer tubes can be used, or the welding structure of profiles and spiral baffles, or the slotted limit structure of profiles can be used. The spiral baffle is composed of multiple spiral plates, and the combined joints can be welded or not....

Abstract

The invention discloses a continuous spiral baffle plate shell-and-tube heat exchanger. The continuous spiral baffle plate shell-and-tube heat exchanger comprises a continuous spiral baffle plate, a heat exchange tube, a baffle plate fixing assembly, a shell, a tube plate, a shell connecting tube, a tube box and a tube box connecting tube, wherein the spiral baffle plate is fixed through the baffle plate fixing assembly. The continuous spiral baffle plate is formed by splicing a plurality of spiral baffle plates with spiral rotating angles of 90-360 degrees, and the splicing parts can be connected by welding, or connected by using fasteners, or not connected.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger with continuous spiral baffles, which belongs to the field of chemical equipment. Background technique [0002] The shell-and-tube heat exchanger, also known as the shell-and-tube heat exchanger, is a partitioned heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This kind of heat exchanger has the advantages of simple structure, low cost, wide cross-section and easy cleaning of scale. It is one of the main process equipments in industrial production processes such as petroleum, chemical industry, refrigeration, metallurgy and power. Shell-and-tube heat exchangers mainly include fixed tube-sheet type, U-shaped tube type, floating head type, stuffing box type, etc. No matter what kind of shell-and-tube heat exchanger, it is basically composed of shell, heat exchange tube, tube sheet, folding Flow plate (baffle) and pipe box and other component...
