Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a compressor air intake filter cover disassembly and assembly lifting device. Background Art

[0002] A hydrogenation heat exchanger is a heat exchange device used for high-pressure hydrogenation reactions. Its principle is based on heat conduction and the flow of heat exchange media, and uses heat conduction and convection to achieve heat transfer. In a high-pressure hydrogenation heat exchanger, heat is conducted through heat exchange pipes. Heat exchange pipes are generally made of metal materials and have good thermal conductivity. Heat is conducted from the heating medium to the heated medium through the pipe wall. During the heat exchange process, the heating medium enters the heat exchanger through the pipe and flows over the surface of the heat exchange pipe near the pipe wall. Since the temperature of the heating medium is higher than that of the heated medium, the heat will be conducted to the heated medium through the pipe wall. At the same time, the heated medium is also flowing in the pipe, and this flow will take away part of the heat, thereby increasing the effect of heat transfer.

[0003] During the use of the hydrogenation heat exchanger, carbonization will form and cause internal blockage. In order to ensure the normal operation of the device system, a core extraction inspection will be carried out every year. During the core extraction inspection, the heat exchanger cover will be disassembled and installed. Due to the large size and heavy weight of the cover, it is time-consuming and laborious to carry it. Previously, there was a lack of experience in disassembly of heat exchanger tube bundles for maintenance, and there was a lack of certain special tools on site to drive the cover to be disassembled and installed, making the disassembly and transportation of the cover more troublesome, causing certain difficulties for the maintenance work and reducing the maintenance work efficiency.
