Technical field
The present invention relates to a kind of plate type heat exchanger, it is mainly used in the heat exchange that plate journey is steam (especially containing oil vapour)
Device, such as condensing unit, vaporising device and fluid heater.
Background technique
It is existing by vapor condensation at the heat exchanger of liquid phase, such as condenser, mainly include that shell-and-plate (inhale by water in shell side
Heat), air-cooled (normal temperature air makees cold energy) and evaporate cold type (being absorbed heat by water evaporation).In above-mentioned heat transfer process, plate journey (belongs to
In tube side) in liquid phase (condensate liquid) gradually increase.In addition, oil-containing in some media, is easy to form oil in heat exchanger inner surface
Film.The formation and accumulation of condensate liquid and oil film will seriously affect media flow speed in heat exchanger, and heat exchange efficiency is caused to reduce.?
In compressor assembly, the formation and accumulation of condensate liquid and oil film also result in compressor and increase energy consumption because pressure at expulsion increases.
Especially in the higher place of environment temperature, Compressor Discharge Pressure is excessively high also to generate security risk.
The Chinese patent application of Publication No. CN104132557A is related to a kind of " intermediate drain formula high-efficiency condensation system.Its
Intermediate drain is implemented in prime heat exchanger end, this measure accelerates the discharge of liquid film, so that the coefficient of heat transfer be made to rise.And
And the utilization rate of heat exchanger heat-transfer surface is effectively increased, it ensure that prime heat exchanger is in high efficient heat exchanging state always.By making
With discovery, although the intermediate drain measure can have certain effect in terms of improving heat exchange efficiency, due to its way be by
Condensate liquid draws heat exchanger, and this part draws medium and is generally gas-liquid mixed phase, and still storing has very high thermal energy, on the one hand can make
It is reduced at heat utilization rate, on the other hand, increases the operating load of refrigeration system.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of plate journey shunt plate heat exchangers, will be in plate journey fluid
Liquid phase of the part including oil is introduced into individually auxiliary plate after concentrating confluence by inlet side collector, accelerates liquid phase discharge,
The content of the liquid phase and oil by main body heat exchanger fin is greatly lowered, to improve device overall heat exchange efficiency.
Technical scheme is as follows:
Plate journey shunt plate heat exchanger, including shell and be mounted in shell and more than two heat exchange mould arranged up and down
Block, heat exchange module include several main heat exchange plates and a certain number of auxiliary heat-exchanging plates installed side by side, heat exchange plate
Medium inlet side is equipped with inlet side collector, and medium outlet is equipped with outlet collector, and inlet side collector is changed by mainboard piece inlet pipe connection master
Hot plate piece, and auxiliary heat-exchanging plate is connected by auxiliary plate inlet pipe；The outlet collector of a upper heat exchange module is connected by connecting tube
Connecing the inlet side collector of next heat exchange module, it is characterised in that: auxiliary heat-exchanging No. of plates is n1 in top layer's heat exchange module, it
Auxiliary heat-exchanging No. of plates is that auxiliary heat-exchanging No. of plates is n3 in n2, then next layer of heat exchange module in next layer of heat exchange module,
The rest may be inferred, and n1, n2, n3 represent natural number, and the quantity of auxiliary heat-exchanging plate is not zero at least one layer of heat exchange module；?
It is arranged in the heat exchange module of auxiliary heat-exchanging plate, the tie point between mainboard piece inlet pipe and inlet side collector is higher than auxiliary plate inlet pipe
With the tie point between the collector of inlet side.
Preferably, the quantity of auxiliary heat-exchanging plate gradually increases in top-down each heat exchange module.
Preferably, the tie point between mainboard piece inlet pipe and inlet side collector is located at the centre of inlet side collector short transverse, auxiliary
The tie point helped between plate inlet pipe and inlet side collector is located at the bottom side of inlet side collector.
Preferably, auxiliary heat-exchanging plate is mounted on the same side of heat exchanger in each heat exchange module.
The positive effect of the present invention is:
One, present invention utilizes the confluence of inlet side collector and gas-liquid separating function, most of gas phase (steam) flows through main body heat exchange
Plate, most of liquid phase (including oil) enter auxiliary heat-exchanging plate.Since confluence acts on liquid phase flow faster, to improve liquid
Phase thermal coefficient, and the velocity of discharge of liquid phase is improved, heat exchange efficiency is improved on the whole.And due to liquid in main body heat exchange plate
Mutually and oil component (oil film) significantly reduce, heat exchange effect be improved significantly.In the case where realizing equivalent heat exchange amount, benefit
Heat exchanger specification can be greatly lowered with the present invention, so that the manufacture of heat-exchanger rig, O&M cost be greatly reduced, and reduce
Heat-exchanger rig occupied area.
Two, it in optimisation technique scheme, is provided in next module compared with the more auxiliary heat-exchanging plates of a upper module.It is this to set
Meter ensures that plate journey fluid flows from above to below in heat transfer process, and the liquid phase output gradually increased can shunt in time, it is ensured that heat exchange
Device balance movement always, obtains more optimized heat transfer effect.
Three, auxiliary heat-exchanging No. of plates of the present invention is less and is mounted on the same side of heat exchanger, is more convenient for dismantling oil removing,
And a large amount of main heat exchange plate trapped fuel amount is effectively controlled, and extends complete machine maintenance period.
