Anti-impact mechanism for heat exchanger

Abstract

The invention discloses an anti-impact mechanism for a heat exchanger. The anti-impact mechanism comprises a first anti-impact plate mounted at a steam inlet of the heat exchanger; a plurality of rows of heat exchange tubes are arranged inside the heat exchanger in the length-wise direction; baffle plates are vertically disposed in the inner wall of the heat exchanger; a partition is disposed in the center of the heat exchanger in the length-wise direction; the baffle plates are fixed between the inner wall of the heat exchanger and the partition; a second anti-impact plate leading to the steam inlet is perpendicularly arranged on the corresponding baffle plate; one end of the second anti-impact plate is fastened to the corresponding baffle plate; a steam flow gap forms between the other end of the second anti-impact plate and the outlet end of the steam inlet. The anti-impact mechanism is simple in structure; after assembly, the anti-impact plates, the partition and the baffle plates can be jointly mounted inside a heat exchanger housing; assembly is convenient and fast; steam impact pressure can be reduced by the anti-impact plates without perforating the anti-impact plates; production cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to an anti-shock mechanism of a heat exchanger. Background technique [0002] In the prior art, the heat exchanger includes multiple rows of heat exchange tubes installed in the heat exchanger shell, and the steam inlet is set on the heat exchanger shell. On the heat pipe, it is easy to cause erosion to the heat exchange tube. In order to avoid this kind of problem, a baffle is generally installed at the air inlet, and a hole for inflowing steam is opened on the baffle to reduce the impact pressure, but it is inconvenient to install and has a great impact on the heat exchange effect. . Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a heat exchanger anti-shock mechanism with simple structure, convenient installation and little influence on heat exchange effect.
