Description

Technical Field

[0001] The utility model relates to a tube-plate type heat exchanger, in particular to a tube-plate type heat exchanger. Background Art

[0002] The tube-sheet heat exchanger is a common heat exchange equipment, which is mainly composed of multiple parallel heat exchange plates and connecting plates. Its working principle is that in the heat exchange equipment, the treated hot medium flows along the heat exchange plate or flow channel, and exchanges heat with the cold medium through the heat transfer surface, thereby transferring heat from the hot medium to the cold medium.

The above still exists. When using the tube-sheet heat exchanger, medium one is injected from the water inlet pipe one, and medium one flows from the heat transfer pipe inside the tube-sheet heat exchanger. Then medium two is injected from the water inlet pipe two, and medium two flows from the inner wall of the tube-sheet heat exchanger, thereby realizing heat exchange. Then medium one and medium two are injected from the water outlet pipe one and the outlet pipe one, respectively. The water is discharged from the outlet pipe 2. When the medium 1 is injected into the tube-sheet heat exchanger through the inlet pipe 1, it is not convenient to filter the medium 1. If the medium is mixed with impurities, it is easy to cause the heat transfer tube to be blocked, thereby affecting the heat exchange work.
