Abstract

The invention relates to a shell and tube heat exchanger easy to repair. The shell and tube heat exchanger comprises a shell, a heat-exchange tube bundle, an A-medium inlet pipe, an A-medium outlet pipe, a B-medium inlet pipe, a B-medium outlet pipe and end sockets. The A-medium inlet pipe is provided with an A-medium inlet regulating valve, a leakage detection pipe is communicated to the A-medium inlet pipe between the A-medium inlet regulating valve and the shell and is provided with a leakage detection regulating valve, and the A-medium outlet pipe is provided with an A-medium outlet regulating valve. Existing tube leakage detection manner is changed, detection processes and steps are simplified greatly, and special detection devices are not needed.

Description

technical field [0001] The invention relates to a tube and tube heat exchanger which is easy to maintain and belongs to the technical field of heat exchangers. Background technique [0002] The shell and tube heat exchanger is currently the most widely used heat exchanger in chemical and alcohol production. It is mainly composed of shell, tube sheet, heat exchange tube, head, baffle and so on. During heat exchange, one kind of fluid enters from the connecting pipe of the head, flows in the pipe, and flows out from the outlet pipe at the other end of the head, which is called the tube side; The other pipe on the shell flows out, which is called a shell-side shell-and-tube heat exchanger. However, due to the large number of tubes, it is time-consuming and labor-intensive to detect whether the tubes are leaking. [0003] Chinese patent document CN101408466A (application number 200810174216.4) discloses a detection method and device, especially a leak detection method and dev...
