Embodiment
A kind of flooded evaporator, including provided with housing 1, it is sequentially provided with anti-corrosion internal and external threads from below to up in housing 1
Heat exchanger tube 2, gas averaging board 3 and air-breathing baffle plate 4, anti-corrosion internal and external threads heat exchanger tube 2 are many and combine and be uniformly distributed arrangement, housing 1
Side wall on be additionally provided with wallboard 5, wallboard 5 is on two sides of the lower section of gas averaging board 3, and the both sides of air-breathing baffle plate 4 are uniform
It is distributed with and keeps off hole 6 provided with two row's air-breathings, the top and bottom of the housing 1 is respectively equipped with air entry 15 and refrigerant inlet 7,
The feed liquor baffle plate 8 of triangle, the two of feed liquor baffle plate 8 are provided between refrigerant inlet 7 and the anti-corrosion internal and external threads heat exchanger tube 2
It is uniformly distributed to discharge on liquid gear hole 9, the side wall of the housing 1 provided with two on the wall of side and is additionally provided with floating ball type liquid level sensor 10, floats
One end of ball liquid level sensor 10 is arranged on the gap between the gas averaging board 3 and the air-breathing plate washer 4, floating ball type liquid level
The other end of sensor 8 is arranged on the gap in the anti-corrosion internal and external threads heat exchanger tube 2, and 3 points of the gas averaging board is that upper strata is more
It is respectively uniformly distributed on the silk screen layer 13 of orifice plate 11, lower floor's porous plate 12 and centre, upper strata porous plate 11 and lower floor's porous plate 12
There are the porous 11-1 in upper strata and the porous 12-1 of lower floor, the porous 11-1 in upper strata and the porous 12-1 of lower floor are described in the arrangement that is dislocatedly distributed
Silk screen layer 13 is made of 304 materials, is distributed with the space between the air-breathing baffle plate 4 and the air entry in the second anti-corrosion
External screw thread heat exchanger tube 2-2.
A kind of application method of flooded evaporator：
Liquid enters the housing 1 of flooded evaporator after the processing of shell and tube condenser 16 from refrigerant inlet 7
Inside, liquid first touches feed liquor baffle plate 8, rises to anti-corrosion internal and external threads heat exchanger tube 2 from the feed liquor gear hole 9 of feed liquor baffle plate 8, passes through
Cross and become gas after anti-corrosion internal and external threads heat exchanger tube 2 is handled and continue to rise, wallboard 5 is encountered in both sides, and gas is converged to toward centre
At plate 3, gas is respectively through the porous 12-1 of lower floor of lower floor's porous plate 12, the silk screen layer 13 in middle level, from upper strata porous plate 11
The porous 11-1 in upper strata rise to air-breathing baffle plate 4, gas is from spiral shell inside and outside the air-breathing gear anti-corrosion of hole 6 to the second of the both sides of air-breathing baffle plate 4
At line heat exchanger tube 2-2, after anti-corrosion internal and external threads heat exchanger tube 2-2 heat treatments, gas is risen at air entry 15, and gas is by air-breathing
The connection of mouth 15 enters in magnetic suspension compressor 17.
The liquid level of flooded evaporator is higher, but floating ball type liquid level sensor 10 ensures that liquid level is not last excessively anti-
Rotten internal and external threads heat exchanger tube 2, could be really all in gaseous refrigerant so in the presence of anti-corrosion internal and external threads heat exchanger tube 2
Under agent situation, amount reduces the probability for wherein having liquid refrigerant unexpectedly, the gaseous refrigerant got on from anti-corrosion internal and external threads heat exchanger tube 2
Uniformly pass through gas averaging board 3 so that the power of the top air entry 14 of flooded evaporator will not be to the liquid of flooded evaporator
Position state refrigerant produces disturbance, and such flooded evaporator Liquid level accuracy is just ensured, heat transfer uniformity and effect
Rate can exactly be improved.Because the direction that the hole of upper strata porous plate 11 and lower floor's porous plate 12 misplaces changes, refrigerant is obstructed,
Will not directly it rise, the secondary stop of middle silk screen layer 13, it can be ensured that liquid level refrigerant is difficult to, by gas averaging board 3, so may be used
To greatly reduce the risk that liquid refrigerant enters compressor, because the housing 1 of flooded evaporator is tubular, air entry 14
It must design at top, liquid level refrigerant can produce one kind and climb wall phenomenon because of air-breathing power, make liquid refrigerant both sides（Directly
Footpath direction）Liquid level can be higher than centre（The center of circle）.This phenomenon can be referred to as " the unrestrained phenomenon of rolling ", and such a phenomenon can easily increase compression
Machine returns liquid risk, and the waste of middle anti-corrosion internal and external threads heat exchanger tube 2 can be caused in addition.So the so many rear strick precaution knot of increase
Structure to prevent risk here generation.
