Abstract

The invention belongs to the technical field of heat exchangers and particularly relates to a composite tube plate for a heat exchanger and the heat exchanger containing the same. The composite tube plate for the heat exchanger sequentially comprises a metal pore plate, a polytetrafluoroethylene tube plate and a metal reinforcing plate. The metal pore plate, the polytetrafluoroethylene tube plateand the metal reinforcing plate are fixed to form an integral structure through connecting pieces. Sealing components are arranged between the metal pore plate and the polytetrafluoroethylene tube plate as well as between the polytetrafluoroethylene tube plate and the metal reinforcing plate. The outer surface of the metal pore plate and / or the outer surface of the metal reinforcing plate are / is coated with a corrosion-resistant material. By means of the composite tube plate for the heat exchanger and the heat exchanger containing the same, integral mechanical strength of the polytetrafluoroethylene tube plate is greatly enhanced; the requirement that the deformation quantity of the polytetrafluoroethylene tube plate is within an acceptable range even under the working conditions of the high pressure and temperature can be met; the problem that the heat exchanger is destroyed due to deformation of the polytetrafluoroethylene tube plate is avoided; and use safety of the heat exchanger is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, and in particular relates to a composite tube sheet for a heat exchanger and a heat exchanger including the composite tube sheet. Background technique [0002] A heat exchanger is a device that transfers (part of) heat from a hot fluid to a cold fluid, also known as a heat exchanger. It is widely used in metallurgy, petroleum, chemical industry, electric power, food, pharmaceuticals and other fields. [0003] In existing heat exchangers, especially heat exchangers with heat exchange tubes made of silicon carbide, the ends of the heat exchange tubes are generally fixed and sealed by tube sheets, that is, the two ends of the heat exchange tubes are generally installed on Two tube sheets. Corrosion of heat exchangers is common in a large number; at present, in the pharmaceutical and chemical industries, the recovery of media containing strong acids and strong alkalis is a relatively big pro...
