Description
Technical field
The present invention relates to a kind of heat exchanger, particularly relates to a kind of new Spiral baffle tubular heat exchanger,
Belong to heat exchange equipment technical field.
Background technology
Heat exchanger is a kind of process equipment for carrying out heat exchange operation, is widely used in chemical industry, oil refining, power, metallurgy, original
In the industrial departments such as sub- energy, shipbuilding, food, refrigeration, building, electronics, aviation.Most commonly used in traditional heat exchangers is arch
Deflection plate, due to exist choked flow and pressure drop are big, have flow stagnant dead band, easy fouling, heat transfer mean temperature difference is small, under vibration condition easily
The defects of failure, gradually substituted in recent years by helical baffles, and preferably helical baffles should have continuous spiral shell
Revolve curved surface.
Current domestic Spiral baffle tubular heat exchanger structural style is various, but is substantially divided into continuous helical deflecting plate
Structure and the discontinuous major class of spiral baffling harden structure two.Discontinuous spiral baffle heat exchanger is current domestic and international helical baffles
The first generation spiral baffle heat exchanger gone out that the main flow of heat-exchanger products, i.e. the early 1990s in last century are developed, by several
1/4 fan-shaped plan plate substitutes the alternate connection of curved surface and forms approximate helicoid, is interrupted strong from shell side entrance to exit
Promote.The heat exchanger helical baffle plate of this form can cause the effect that shell-side segment fluid flow is in approximate helical flowing.Compare
In segmental baffle, under identical operating mode, such deflection plate (being referred to as discrete helical baffles) can reduce pressure drop
45% or so, and overall heat-transfer coefficient can improve 20%~30%, under identical thermic load, can greatly reduce size of heat exchanger.
Although the process technology comparative maturity of current discontinuous helical baffles, being also promoted in petrochemical industry should
With, but still suffer from many weak points.For example, fanning strip be by with the certain angle of shell side axis is end to end puts successively
, cause adjacent two pieces of deflection plate junctions breach to be present into the acute angle transition of Non-smooth surface, can be to the fluid production to axial movement
Raw back-pressure effect, when fluid by when, energy loss can be caused suddenly by turning to, and when helical angle is larger, then energy consumption is more serious；Cause
This in order to improve this spiral baffle heat exchanger heat exchange efficiency so adjacent two panels fanning strip space articulation when, it is necessary to additional angle
Fishplate bar could filling chink, so not only taken a lot of work but also waste material, and increased the resistance of fluid again.
Continuous spiral baffle plate heat exchanger is rapid in recent domestic helical baffles heat exchange product promotes
Another big type, referred to as second generation spiral baffle heat exchanger is characterized in that deflection plate is fixed on central tube, enters from housing
Mouth promotes to outlet, and its shape is similar to complete helicoid compared to the helical baffles of first generation spiral baffle heat exchanger,
Mobile phase is to continuous and stable in housing for medium fluid, but deflection plate can not cover the casing center region of shell side, heat exchange be present
Loss.Simultaneously because this kind of helical baffles surround central, tubular into actually a kind of curved-surface structure, curved-surface structure adds
Work manufacture difficulty is big, is unfavorable for popularization and application of maximizing.
