Cutting type spiral distribution sanitary heat exchanger

Abstract

The invention discloses a cutting type spiral distribution sanitary heat exchanger. The cutting type spiral distribution sanitary heat exchanger comprises an outer tube side (17) and an inner tube side (18) arranged in the outer tube side (17); the outer tube side (17) is internally provided with a first turbulator (10), a second turbulator (11) and a baffle plate (12); the inner tube side (18) comprises a plurality of medium tubes (8) for allowing mediums to circulate; and the medium tubes (8) are internally provided with spiral distributors (9). According to the cutting type spiral distribution sanitary heat exchanger, impact of cold / hot mediums to the medium tubes can be reduced, damage of medium pressure to the medium tubes is reduced, meanwhile, the medium flowing direction is changed, and retention zones are decreased; and the mediums circulate spirally in the medium tubes, residual mediums on the walls of the tubes are decreased, the mediums can conduct heat exchange more easily, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a shear type spiral split flow sanitary grade heat exchanger. Background technique [0002] Heat exchanger, also known as heat exchanger, is a device that transfers part of the heat of hot fluid to cold fluid. It is widely used in chemical, petroleum, food and many other industrial sectors. It plays an important role in production. It can be used for Heating medium, can also be used for cooling medium. [0003] In the existing structures of various heat exchangers, regardless of media such as steam, chilled water, and process water, the inner tube side will be damaged due to excessive pressure, and the high temperature difference will cause damage to the heat exchanger. Due to the single flow direction, a stagnation area on the container wall will be formed. , so that the heat exchange is not complete, resulting in waste of media, waste of material costs, low heat exchange efficiency, a...

[0003] In the existing structures of various heat exchangers, regardless of media such as steam, chilled water, and process water, the inner tube side will be damaged due to excessive pressure, and the high temperature difference will cause damage to the heat exchanger. Due to the single flow direction, a stagnation area on the container wall will be formed. , so that the heat exchange is not complete, resulting in waste of media, waste of material costs, low heat exchange efficiency, and short service life.
