Anti-corrosion marine heat exchanger with filtering device

Abstract

The invention relates to the technical field of heat exchangers, and discloses an anti-corrosion marine heat exchanger with a filtering device. The anti-corrosion marine heat exchanger comprises a heat exchanger body and end covers arranged at the two ends of the heat exchanger body; the inner side walls of the two end covers are fixedly provided with rubber layers; the outer side wall of one of the end covers is symmetrically provided with a water feeding pipe and a water discharging pipe in a communicating mode, and the water discharging pipe and the water feeding pipe are arranged in the vertical direction; the ends, away from the heat exchanger body, of the water discharging pipe and the water feeding pipe are provided with flanges; the water feeding pipe is internally provided with asleeve matched with the inner wall of the water feeding pipe, the position, close to the inner edge of an opening formed in one side of the sleeve is fixedly provided with a filtering net, and the side, away from the filtering net, of the sleeve is fixedly provided with a rectangular ring; and the inner side walls of the flanges are provided with rectangular grooves matched with the rectangular rings, and the rectangular rings are clamped to the opening of the water feeding pipe. The anti-corrosion marine heat exchanger is easy to operate and good in safety, the end covers are high in corrosion resistance, and the stability and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a corrosion-resistant marine heat exchanger with a filtering device. Background technique [0002] Heat exchanger (also known as heat exchanger or heat exchange equipment) is a device used to transfer heat from hot fluid to cold fluid to meet the specified process requirements. It is an industrial application of convective heat transfer and heat transfer. Heat exchangers can be classified in different ways. According to its operation process, it can be divided into three categories: partition type, hybrid type, and regenerative type (or regenerative type); according to the compactness of its surface, it can be divided into two types: compact type and non-compact type. [0003] In the prior art, most marine shell-and-tube heat exchangers use seawater circulation for heat exchange for convenience. There is a hidden danger of inhaling plankton during work, and at the same ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that most marine shell-and-tube heat exchangers in the prior art use seawater circulation for heat exchange for convenience, but there is no seawater filtering device in the water inlet pipe. , so that there is a hidden danger of plankton inhalation when the heat exchanger is working, and at the same time, the corrosion intensity of seawater is high, which easily leads to the problem of corrosion and perforation on the inner surface of the end cover of the heat exchanger.
