Impingement plate structure of heat exchanger

Abstract

The invention discloses an impingement plate structure of a heat exchanger. The impingement plate structure comprises an inlet joint pipe, an impingement plate and ribbed plates; the lower end of the inlet joint pipe is welded on a shell of the heat exchanger; the impingement plate is fixed right below the inlet joint pipe through the two ribbed plates at the lower end of the inlet joint pipe and is located above a heat-exchanging pipe; the impingement plate has a V-shaped cross section, and two ends of the impingement extend to form convex plates; each ribbed plate has an L-shaped cross section, and comprises a long edge and a short edge; the upper end face of each ribbed plate is welded on the inner side wall of the shell, and the long edge of each ribbed plate is vertical to the shell; and the impingement plate is located above the short edge of each ribbed plate, and the bottom face of each convex plate of the impingement plate is welded on the upper surface of the short edge of each ribbed plate. According to the impingement plate structure of the heat exchanger in the scheme disclosed by the invention, the impingement plate structure has a simple structure and can be used for effectively preventing the impingement plate from falling off in a heat exchanger operation process, and thus, the normal operation of the heat exchanger is ensured.

Description

technical field [0001] The invention relates to an auxiliary element of a heat exchanger, in particular to an anti-shock plate structure on the heat exchanger, and belongs to the technical field of heat exchanger auxiliary devices. Background technique [0002] Anti-shock plates are fixed at the inlet joints of the shell side in the heat exchanger. This is because in the heat exchanger, the density of the gas is much smaller than that of the liquid, and the flow rate of the gas is very high when entering the heat exchanger. If the anti-shock plate is not installed for protection, the gas will directly impact the heat exchange tube, causing The heat exchange tube vibrates strongly. The vibration of the heat exchange tubes will not only cause collisions between adjacent heat exchange tubes, or between the heat exchange tubes and the shell, which will cause the heat exchange tubes and the shell to be worn and cracked. In severe cases, the heat exchange tubes will also be hit. ...

AI Technical Summary

Problems solved by technology

Since the anti-shock plates in the prior art are all flat, during the normal operation of the heat exchanger, due to the pressure impact of the medium in the inlet connection pipe, the anti-shock plates often fall off, and the shed anti-shock plates not only cannot protect the heat exchange tubes, and the falling anti-shock plate will also leak the heat exchange tubes on the uppermost layer of the heat exchanger, resulting in a short circuit of the shell side and tube side media of the heat exchanger, making the heat exchange tubes unable to operate normally, and seriously, the heat exchange The tube might be scrapped.
