Baffling element of pipe shell type heat exchanger and working method thereof

Abstract

The invention relates to a baffling element of a pipe shell type heat exchanger and a working method thereof. The baffling element of the pipe shell type heat exchanger comprises a square hole baffle and a casing pipe fixing plate. The square hole baffle is transversely arranged in a shell of the pipe shell type heat exchanger and used for fixing a corrugated pipe. The square hole baffle is a circular hole plate matched with the inner diameter of the shell, and is uniformly provided with a plurality of square through holes. The casing pipe fixing plate is embedded into the square through holes, and the inner side of the casing pipe fixing plate is tangent to the wave crest portion of the corrugated pipe. By adopting the square hole baffle, the casing pipe fixing plate is arranged in the square through holes for fixing the corrugated pipe, the heat exchange effect of the heat exchanger shell pass can be effectively improved, the fluid turbulent degree is enhanced, vibration of the heat exchanger is reduced, and the problem of abrasion caused between a corrugated pipe bundle and a baffle plate is solved.

Description

technical field [0001] The invention relates to the technical field of fluid heat exchange, in particular to a baffle element of a shell-and-tube heat exchanger and a working method thereof. Background technique [0002] Traditional shell-and-tube heat exchangers usually use straight tube heat exchange tubes and bow-shaped baffles, which have problems such as low heat exchange efficiency, fast deposition of dirt in the heat exchanger, and difficult cleaning of dirt. In recent years, the matching form of bellows and full-circle orifice has appeared, but the wear and tear between bellows and baffles is easy to occur, and pipe sleeves need to be added during installation, which increases the cost; in addition, the full-circle orifice and corrugated The structure of the tube fit is easy to cause the tube side structure to be unstable, the fluid is not easy to achieve turbulent flow, and the heat exchange effect is not good.
