Setups modus of short-circuit-proof spiral baffle plate shell-and-tube heat exchanger draw rod

Abstract

It aims to solve the low heat exchange issue of common tubular shell spiral folding plate, and it features in each projection being 360degree / 4 fan baffle plate with two straight lines extended to 10mm to 100 mm, with the pulling pole going through the central axial line of the shell and two vertical line through the overlapping part of the baffle plate, using pipe spacer to position the baffle plate.

Description

(1) Technical field [0001] The invention relates to a shell-and-tube type spiral baffle heat exchanger in the technological process of petroleum, chemical industry, power generation, metallurgy, food, pharmaceutical and other industries. (2) Background technology [0002] Ordinary shell-and-tube spiral baffle heat exchanger is a kind of high-efficiency and energy-saving partition wall heat exchange equipment. The baffle mode of the medium in the shell is spiral baffle, as shown in Figure 1, a pitch of the shell channel helically propelled is composed of four fan-shaped baffles (4) A, B, C, and D with the same number of quadrants. Each fan-shaped baffle and the axis of the housing (1) form a certain angle, and are arranged in sequence from the front of the housing to the rear of the housing. A triangular space is formed between the fan-shaped baffles of two adjacent quadrants, which is easy to make along the The medium flowing through the fan-shaped baffle forms a short-circ...

AI Technical Summary

Problems solved by technology

At the same time, since the adjacent baffles have no overlapping parts, the tie rods (2) on the baffles cannot be shared, resulting in a large number of tie rods, and because the tie rods occupy the position of the heat exchange tube (5), the heat exchange efficiency of the equipment is affected
