Graphite heat exchanger with cage type drawable baffling ring group

Abstract

The invention discloses a graphite heat exchanger provided with a cage type drawable baffling ring group, which comprises a barrel, an upper graphite seal head and a lower graphite seal head are arranged at the top and the bottom in the barrel, and a cylinder formed by overlapping a plurality of graphite heat exchange blocks is arranged in the barrel between the upper graphite seal head and the lower graphite seal head. An annular flow guide water jacket is formed between the cylinder and the inner wall of the barrel body, and a cage type drawable baffling ring group is arranged in the annular flow guide water jacket. Due to the arrangement of the cage-type drawable baffling ring group, the assembly efficiency is high, the assembly operation is simple and convenient, the one-time assembly qualification rate is high, the service life is long, and the production cost is reduced; the maintenance difficulty and cost are reduced, and the heat exchange efficiency is improved. In addition, the heat exchanger further has the advantages of being completely sealed in baffling, not prone to loosening of the baffle plates, free of abnormal sound and high in heat exchange efficiency.

Description

technical field [0001] The invention relates to a graphite heat exchanger, in particular to a graphite heat exchanger provided with a cage-type drawable baffle ring group. Background technique [0002] The round-hole graphite heat exchanger is the most widely used heat exchange equipment for strong corrosive medium in the category of graphite heat exchangers, and the market demand is very large. Many problems are exposed in production practice: [0003] 1. The cylinder body is manufactured by riveting welding process, which is restricted by manufacturing conditions, and its roundness and dimensional accuracy are limited, resulting in uneven annular gap between the cylinder body and the heat exchange block. [0004] 2. The annular baffle is made of steel, and its rigid material properties cannot completely compensate for the defect of uneven annular gap. [0005] 3. The assembly process requirements of the round block-hole graphite heat exchanger, the assembly process requi...

AI Technical Summary

Problems solved by technology

[0003] 1. The cylinder is manufactured by riveting and welding process. Due to the restriction of manufacturing conditions, its roundness and dimensional accuracy are limited, resulting in uneven circumferential gap between the cylinder and the heat exchange block

[0004] 2. The annular baffle is made of steel, and its rigid material properties cannot fully compensate for the defect of uneven annular gaps

[0005] 3. The assembly process requirements of the graphite heat exchanger with round holes, the assembly process requires that there must be enough assembly clearance, resulting in the final baffle clearance being too large, which affects the baffle effect and reduces the heat transfer coefficient

[0006] 4. The metal baffle corrodes and expands, making it difficult to disassemble and maintain; the baffle cannot be replaced, making it difficult to maintain; it is even more difficult to disassemble and maintain independently
