Description
Technical field
The present invention relates to heat exchange equipment technology more particularly to a kind of multiple-unit composite screw plate heat exchangers.
Background technique
Heat exchanger be different temperatures two or more fluid between realize heat transfer energy-saving equipment, simultaneously be also
Improve one of the capital equipment of energy utilization rate.Heat exchanger is many kinds of, wherein spiral heat exchanger is by two parallel metals
Two helix-type channels are made in coiled sheet, have the characteristics that heat exchange area is big, good heat-transfer, the processing is simple, be widely used in electric power,
Petrochemical industry, medicine and other fields.
Nineteen thirty Sweden ROSENBLAD company first proposed spiral-plate heat exchanger structure, and subsequent development is mainly had in mind
In reduction manufacturing process difficulty, heat exchange efficiency is improved, and proposes a variety of corrective measures.Such as: patent CN105627795A is adopted
Replace spacing column with the salient point rolled in advance, reduces difficulty of processing, and pass through the most outer welding energy wave generation in end plate
Device, the energy wave that energy wave producer generates can be effectively transmitted on each circle heat-transfer surface by end plate, realize that antiscale removes
The purpose of dirt；Patent CN106288888A combines the advantages of plate-fin heat exchanger and spiral-plate heat exchanger, is replaced using fin
Spacing column improves the rigidity, stability and intensity of spiral plate, while fin increases heat transfer area, and fin flow guiding hole is improved
Liquid fluidity, further improves heat exchange efficiency；Patent CN102445095B exchanges heat traditional binary channels spiral plate type
Device is changed to multichannel, and traditional flat substrate is changed to corrugated plating, and traditional strip of paper used for sealing arc welding is changed to bonding weldering or pours cast welding, compared with
Conventional helical plate heat exchanger, can exponentially increase the treating capacity of heat exchanger, improving work efficiency simultaneously reduces processing cost；Patent
Helical fissure heat exchanger plates are rolled into roll-shaped by CN101660875B, and two heat exchanger plates bulge the mutual jacking in position, form heat exchange
Channel, the heat exchange area of heat exchanger can increase by 70% or more, and bearing capacity is big, consumptive material is few, high-quality, easy maintenance, is convenient for
Cleaning；Spacing helical duct is changed to channel cross-section and is gradually increased or becomes along flow direction of medium by patent CN104329971B
It is small, suitable for hot side fluid or cold-side fluid heat transfer process since temperature change causes dynamic viscosity coefficient to change greatly
Application has the characteristics that principle is simple, easy to use, high reliablity, energy conservation.
In conclusion occur in recent years it is a variety of by adjusting spiral plate surface texture, change the means such as channel size and mention
High spiral-plate heat exchanger heat exchange efficiency, the processing method for reducing difficulty of processing, however, it is wider to be limited to spiral-plate heat exchanger runner
The features such as, it still has following disadvantage and urgently overcomes: 1, when Flow Field Distribution is blocked there are inhomogeneities, especially local flow channel, easily
There is dead zone, influences heat exchange efficiency；2, it is difficult to monitor the validity of internal structure in real time, for example is difficult to real-time acquisition office
Portion's clogging；3, due to the presence of the support constructions such as spacing column, it is difficult to exchange hot plate and carry out depth cleaning；4, due to modularization
Degree is lower, if situations such as corrosion, leakage locally occurs in spiral plate, maintenance replacement cost is higher.
