A vertical baffle rod heat exchanger with longitudinal partitions

Abstract

The invention discloses a vertical baffling-rod heat exchanger with longitudinal partition plates. The vertical baffling-rod heat exchanger with the longitudinal partition plate comprises a housing, a tube plate and a heat exchange tube bundle, wherein multiple supporting strips arranged on the periphery are adopted for fixing the whole heat exchange tube bundle and play the effect of a slide way. Multiple groups of baffling-rod modules are arranged in the axial length of the heat exchange tube bundle, and each group of baffling-rod modules comprises a group of transverse baffling rods and a group of longitudinal baffling rods which are arranged on a set-length baffling ring at 90 degrees. Multiple gap type longitudinal partition plates are arranged in the housing, the transverse baffling rods and the longitudinal baffling rods penetrate through a gap between every two heat exchange tubes, and meanwhile the transverse baffling rods penetrate through holes in the gap type longitudinal partition plates. A high-position non-condensable-air outlet is formed in the position of a shell pass, close to the tube plate, and meanwhile the shell pass is provided with a liquid-sealing barrel section close to a bent tube section of the heat exchange tube bundle. The tail portion of the tube bundle is of a grid vibration-proof structure.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a vertical baffle rod heat exchanger with longitudinal partitions. Background technique [0002] The baffle heat exchanger (RodBaffleHeatExchanger) was pioneered by the Philips Petroleum Company of the United States in 1970. Its original intention was to eliminate the fluid-induced vibration in the baffle heat exchanger. It is different from the commonly used baffle heat exchanger. , the heat exchange tube is supported by a baffle ring group composed of baffle rods, and the tubes are fixed in four directions: up, down, left, and right. The shell-side fluid flows axially, which eliminates the vibration induced by the fluid repeatedly flowing laterally through the tube bundle; there is no flow dead zone, and it is not easy to scale; the shell-side flow resistance is small, and the degree of turbulence is increased, thereby enhancing heat transfer. Therefore, the baffle rod heat ex...

AI Technical Summary

Problems solved by technology

[0007] The present invention provides a vertical baffle rod heat exchanger with longitudinal baffles, which is used to overcome the baffle heat exchanger in the prior art when the equipment is vertical, due to the gas condensation descending to the baffle along the heat exchange tube. On the board, it is easy to accumulate liquid, which reduces the problem of heat transfer efficiency
