Front end cover for anti-corrosion shell-and-tube heat exchanger and manufacturing method of front end cover

Abstract

The invention discloses a front end cover for an anti-corrosion shell-and-tube heat exchanger and a manufacturing method of the front end cover, and relates to the technical field of heat exchangers. The front end cover comprises an end cover body, a feeding pipe and a discharging pipe. The front end cover is mainly composed of the end cover body and an anti-corrosion assembly, the end cover body is made of cast iron, the outer portion of the anti-corrosion assembly is made of engineering plastics, the end cover body has the characteristics of being hard in texture and not prone to deformation, the anti-corrosion assembly can be protected in the dismounting and mounting process, the anti-corrosion assembly is prevented from being damaged by external force, and therefore the service life of the anti-corrosion assembly is prolonged; and the end cover body and the anti-corrosion assembly adopt split type design, after the anti-corrosion assembly or the end cover body is damaged after being used for a long time, the anti-corrosion assembly and the end cover body can be separated, the anti-corrosion assembly or the end cover body which is not damaged can be reused, waste of materials is avoided, and therefore the manufacturing cost of enterprises is saved, the weight of the front end cover is greatly reduced through combination of the end cover body and the anti-corrosion assembly, and the front end cover is convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a front end cover for an anti-corrosion shell-and-tube heat exchanger and a manufacturing method thereof. 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 , Shell and tube heat exchangers are also called shell and tube heat exchangers. It consists of shells, heat transfer tube bundles, tube sheets, baffles (baffles) and tube boxes. The shell is mostly cylindrical, with a tube bundle inside, and the two ends of the tube bundle are fixed on the tube sheet. There are two kinds of hot and cold fluids for heat exchange, on...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a front end cover for an anti-corrosion shell-and-tube heat exchanger and its manufacturing method, which solves the problem that the traditional heat exchanger end cover is very bulky, inconvenient to install and disassemble, and requires large auxiliary equipment. The front end cover of the heat exchanger is made of cast iron or copper, which is prone to trachoma, resulting in leakage and poor sound insulation, which affects the surrounding working environment
