The heat exchanger of gas-liquid separation, belongs to technical field of heat exchangers.
Background technology
Plate type heat exchanger is most efficient heat-exchange device, and the sides adjacent of every piece of heat exchanger plates is usually the stream of different working medium
Road, with the refrigeration working medium in a side runner by the gas cooling in another side runner；When side medium is coolant, opposite side is situated between
When matter is the gas of warm and moist, this be full of the gas of a large amount of steam in heat transfer process due to condensation can separate out it is substantial amounts of
Aqueous water is remained in the medium runner of plate type heat exchanger, so that the heat exchange operation to normal heat exchanger is impacted, therefore often
The way of rule is to need external gas-liquid separation device to isolate first to steam, but so not only causes whole system
It is bulky, and virtually add the manufacturing cost of equipment；There are Corporation R ＆ D such as Chinese patent for this
" a kind of vapor-liquid separating device and the heat exchanger with gas-liquid separating function " disclosed in ZL201420852551.6, it divides gas-liquid
Be integrated in from function on heat exchanger, but its still using vapor-liquid separating device carry out vapor-liquid separation operation, be only by its
Simple concatenation is carried out in structure, inreal realize carries out gas-liquid separation while heat exchange.
The content of the invention

The gap h1 of font ripple；
After first heat exchanger plates and the second heat exchanger plates are staggeredly superimposed successively, the first liquid storage hole and the second liquid storage hole up/down perforation structure
Into a liquid storage area, and leakage fluid dram is communicated to the liquid storage area.
A kind of plate type heat exchanger for steam-water separation of the invention, above-mentioned refrigerant import is led to first passage hole three, second
Road hole three connects；Refrigerant exit with first passage hole one, second channel hole one with connecting；Air inlet and first passage hole
2nd, second channel hole two connects.
A kind of plate type heat exchanger for steam-water separation of the invention, the first heat exchanger plates and the second heat exchanger plates are staggeredly superimposed successively
Staggered two media runner is constituted, coolant media flows out via refrigerant import, coolant media runner, refrigerant exit；Gas
The vapor that body medium enters in gas medium runner, gas via air inlet enters from the heat transfer zone in gas medium runner
During vapor-liquid separation area, the gap between the concavo-convex herringbone ripple set due to vapor-liquid separation area is more than what is set on heat transfer zone
Gap between herringbone ripple so that the volume of vapor-liquid separation area gas side runner is more than the appearance of heat transfer zone gas side runner
Product, therefore gas, when entering vapor-liquid separation area, because passage becomes big, flow velocity diminishes, and the small water droplet carried secretly in gas can enter one
Step is separated, and is attached to heat exchange plate surface, and is flowed downward along air-flow, and finally flow to liquid storage area deposition, and goes water removal
Dry gas after steam is discharged via the gas outlet above liquid storage area.
A kind of plate type heat exchanger for steam-water separation of the invention, when the liquid deposited in liquid storage area reaches its maximum size
When, it is passed through gases at high pressure via air inlet and goes out the liquid of the deposition of liquid storage area via leakage fluid dram.
The width court of herringbone ripple in a kind of plate type heat exchanger for steam-water separation of the invention, the first vapor-liquid separation area
Gradually increase towards the direction of the first liquid storage hole；The width of herringbone ripple is towards towards the second liquid storage hole in second vapor-liquid separation area
Direction gradually increase.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention utilizes herringbone corrugation pitch（Gap between i.e. adjacent herringbone ripple）Change adjust gas
Flow velocity during gas coming through medium runner so that its flow velocity is slack-off, drop cohesion is dropped, and the herringbone ripple after pitch is widened
Gather under the guiding of line into liquid storage area, and now dry gas is flowed out by the gas outlet above liquid storage area, so as to realize
Carry out vapor-liquid separation during heat exchange, and overall structure it is simple, without external vapor-liquid separating device, greatly reduce
Cause, use cost.
