A heat exchange device capable of recovering waste heat from multiple heat sources

Abstract

The invention discloses a heat exchange device capable of realizing heat recovery of multiple heat sources. The heat exchange device comprises a housing, a plurality of heat source output runners arranged at the upper end of the housing, a plurality of heat source input runners arranged at the lower end of the housing and a core connected to the interior of the housing, wherein a plurality of partitions are connected between the outer wall of the core and the inner wall of the housing and divide a cavity formed between the housing and the core into a plurality of heating medium runners allowing a heating medium to pass and a plurality of heat source runners allowing the heat sources to pass, and the heat source runners and the heating medium runners are in alternative distribution; the upper ends of the heat source runners are connected and in one-to-one correspondence with the heat source output runners in a communicating manner; the lower ends of the heat source runners are connected and in one-to-one correspondence with the heat source input runners in a communicating manner; and the upper ends and the lower ends of the heating medium runners are connected with a heating medium input opening in the upper end of the housing and a heating medium output opening in the lower end of the housing. The heat exchange device has the advantages that the number of the heat sources of waste heat can be flexibly increased or reduced, the structure is simple, the occupied space is small and the heat exchange effect is good.

Description

technical field [0001] The invention relates to a waste heat recovery device; in particular, it relates to a heat exchange device capable of realizing recovery of waste heat from multiple heat sources. Background technique [0002] With the acceleration of industrialization and the rapid development of economic construction, energy consumption is increasing, and the requirements for comprehensive utilization of energy are also increasing. In the comprehensive utilization of energy, the heat exchanger is a major process equipment and plays an important role in industrial energy-saving applications. [0003] Industrial waste heat comes from all links of industrial production, so there are many heat sources and their tastes are not the same. At present, the current heat exchanger can only realize the heat exchange between a single heat source and the heat medium. To realize the heat exchange between multiple heat sources and the heat medium, it can be realized by using multipl...

Problems solved by technology

At present, the current heat exchanger can only realize the heat exchange between a single heat source and the heat medium. To realize the heat exchange between multiple heat sources and the heat medium, it can be realized by using multiple heat exchangers connected in parallel. The media is divided into multiple strands to obtain heat from multiple heat sources and then mixed, which will lead to the loss of high-temperature water quality and reduce the temperature of the mixed heat media
