Self-supported type corrugated straight heat exchange tube bundle

Abstract

The invention relates to a self-supported type corrugated straight heat exchange tube bundle which comprises a plurality of heat exchange tubes, wherein the heat exchange tubes are arranged in parallel; each heat exchange tube consists of a corrugated straight tube and a smooth straight tube; the main body of the corrugated straight tube is of a structure of a corrugated straight tube section and a straight tube section, that is, one waveform of a period comprises a wave peak, a straight tube, a wave peak and a wave trough; the smooth straight tubes are arranged at two ends of the corrugated straight tubes and are fixedly connected with a tube plate in a heat exchanger; the heat exchange tubes are self-supported through linear contact of the straight tube sections. By adopting the self-supported type corrugated straight heat exchange tube bundle, the heat exchange efficiency of the heat exchanger can be effectively improved, generation of dirt can be inhibited, abrasion of baffle plates can be avoided, and in addition, the self-supported type corrugated straight heat exchange tube bundle has the advantages of convenience in disassembling, equipment size reduction, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to a heat exchange tube bundle, in particular to a self-supporting corrugated straight tube heat exchange tube bundle used in heat exchange equipment in coking production. Background technique [0002] Traditional heat exchangers usually use straight tube heat exchange tube bundles, which have problems such as low heat exchange efficiency, fast deposition of dirt in the heat exchanger, difficult to clean dirt, expansion joints are required when the temperature difference is large, and high equipment costs. In recent years, heat exchange tube bundles in the form of horizontally grooved tubes, zoom tubes, spiral grooved tubes and corrugated tubes have appeared, but the heat transfer efficiency of spirally grooved tubes and horizontally grooved tube heat exchange tube bundles is relatively low. The processing of the heat exchange tube bundle is difficult, and it is easy to wear and tear with the baffle plate. During installation, tub...

[0002] Traditional heat exchangers usually use straight tube heat exchange tube bundles, which have problems such as low heat exchange efficiency, fast deposition of dirt in the heat exchanger, difficult to clean dirt, expansion joints are required when the temperature difference is large, and high equipment costs.

In recent years, heat exchange tube bundles in the form of horizontally grooved tubes, zoom tubes, spiral grooved tubes and corrugated tubes have appeared, but the heat transfer efficiency of spirally grooved tubes and horizontally grooved tube heat exchange tube bundles is relatively low. The processing of the heat exchange tube bundle is difficult, and it is easy to wear and tear with the baffle plate. It is necessary to add a tube sleeve during installation, which increases the cost
