For improving the device of the operational efficiency of turbine.Substantially, which can be used available surplus refrigerant in system 10
Central fluid is cooled down, which may include water, ethylene glycol or other heat-transfer fluid, which correspondingly leads to
Closed input coolant circuit 50 circulation is crossed with the cooling air inlet for entering turbine.
Referring to fig. 2, in order to provide necessary cooling to air inlet 70,71, the slip-stream of the first refrigerant is from the first refrigerating circuit
20 (that is, from surge tanks 40) are discharged by pipeline 51 and break through expansion valve 52.Due to the first refrigerating circuit 20 for
It in such liquefaction gas processes, therefore does not need to provide new or individual cooling source in this process, thus significantly
Reduce the cost of system.First refrigerant of expansion is before it returns to the first refrigerating circuit 20 by pipeline 54 from expansion valve
52 pass through cocurrent over-heat-exchanger 53.Propane evaporates in heat exchanger 53, so that the temperature of central fluid is reduced, the centre
Fluid correspondingly passes through heat exchanger 53 from the pumping of storage tank 55 by pump 56.
Then, cooling central fluid is pumped to the aerial cooler by being located at the inlet of turbine 24,38
Or cooling device 57,58.As air inlet 70,71 flows into corresponding turbine, aerial cooler or cooling dress are flowed through in air inlet 70,71
The coil pipe etc. in 57,58 is set, before air is transported to its corresponding turbine, correspondingly air inlet 70,71 is carried out cold
But or cool down.Then, the central fluid of warm returns to storage tank 55 by pipeline 59.Preferably, air inlet 70,71 will be cooled to
Not less than about 5 DEG C (41 °F), this is because may freeze at lower temperatures.In certain circumstances, it may be necessary in
Between the antifreezing agent (such as ethylene glycol) with inhibitor is added in fluid, to prevent blocking, equipment damage and control corrosion rate.
An aspect of this disclosure is shown in detail in Fig. 2, wherein humid air plate-fin cooler 104 is connected to
One refrigerating circuit 20.As used in the disclosure, humid air plate-fin cooler 104 is combined: (a) conventional air
(fan 108 can be used in it makes surrounding air flow through cooling fin tube to radiating fin heat exchanger, passes through the fluid of the cooling fin tube
(such as liquid or gas) will be cooled to close to environment temperature (such as dry-bulb temperature)) and (b) by using such as spray head
Liquid (usually water) Lai Jinhang wet type in 110 evaporitic environment air stream of nozzle in 112 is cooling to approach surrounding air
The cooling effect of both lower wet-bulb temperature.
Humid air plate-fin cooler 104 is used for the first refrigerant to the liquid in the pipeline 51 of surge tank 40
Slip-stream carry out supercooling.Overcooled first refrigerant is directed to heat exchanger 53 by pipeline 105.The supercooling of the propane
But the cooling load of heat exchanger 53 and the coefficient of performance of refrigeration system are increased.The coefficient of performance is the refrigeration of heat exchanger 53
Load is divided by for providing the resulting ratio of delta compression machine power of the refrigeration.Humid air plate-fin cooler 104 positions
At the slip-stream of the first refrigerant in the pipeline 51 of cooling Fig. 2 and Fig. 3.Alternatively, humid air plate-fin cooler 104 can be with
It is incorporated to as a part of one or more condensers or cooler 39, with supercooling LPG, the LPG is used
Air cooling is used in the other parts of the liquefaction process before the slip-stream for removing the first refrigerant in pipeline 51 to provide
(directly or indirectly) cooling source of device or cooling device 57,58.However, it preferably only to the propane slip-stream in pipeline 51 into
Row supercooling, so that the maximizing the benefits in terms of gas turbine inlet gas cooling.
According to disclosed aspect, separator 101 and 102 is located at after aerial cooler or cooling device 58,57
Gas turbine air intake in.When air inlet is cool below the temperature of its wet-bulb temperature from its environment dry-bulb temperature,
These separators 101,102 remove the water condensed from air inlet 70,71.Separator 101,102 can be inertial type, such as vertically
Blade, coalescing element, low speed bellows or any other type well known by persons skilled in the art water-separator or demister.
Gas turbine air intake may include filter element such as air filter 41, can be located at aerial cooler or
The upstream or downstream of cooling device 57,58 and separator 101,102 or the upstream and downstream positioned at them.Preferably, at least
One filter element is located at the upstream of cooler and separator.The air filter element may include moisture barrier, such as can be with
EPTFE (expansion PTFE) film of GORETEX trademark Soynatto, may be in the condensed water removed by separator 101,102 with removal
Big aerosol, dust, salt or other pollutants of aggregation.By with gas turbine 24 and/or 38 associated coolers and
At least one filter element or similar device is arranged in the upstream of separator, can make the atmosphere pollution in the moisture (water) collected
It minimizes, can be minimized the fouling and corrosion of cooler and separator, can also control and minimize humid air heat radiation type
The fouling and corrosion of cooler 104.
In the cooling period of gas turbine air inlet 70,71, most cooling load for condensed gas turbine into
Moisture in gas 70,71, rather than simply reduce the dry-bulb temperature of air inlet.As an example, being if to cool down dry-bulb temperature
The air inlet that 40 degrees Celsius and wet-bulb temperature are 24 degrees Celsius, then effective specific heat of air is about 1kJ/ between 40 DEG C and 24 DEG C
Kg/ DEG C, but moisture is reduced and is condensed out from air with dry-bulb temperature, effective specific heat is when being lower than 24 DEG C of wet-bulb temperature
About 3kJ/kg/ DEG C is increased to significantly.From this it can be concluded that the pact for the cooling air lower than wet-bulb temperature (dew point)
2/3rds cooling load is wasted, this is because the small composition transfer of the air for gas turbine 24 and/or 38
Only generating very little to the available power of gas turbine influences.The condensed moisture substantially has and enters the cold of gas turbine
But the identical temperature of air inlet and being used for is located at aerial cooler or cooling device 57 or 58 fronts in the gas flow
The a degree of pre- of air inlet 70,71 is provided similar to the other cooling coil of aerial cooler or cooling device 57 or 58
It is cooling.However, the part cooling load that the arrangement can only compensate for reducing water temperature, and the part for condensed water cannot be compensated
Cooling load.That is, the heat of evaporation of water cannot by using gas turbine air inlet carry out hot transmitting or wet type it is cooling come
Compensation.
Greater portion for cooling load that is cooling and condensing the moisture from gas turbine air inlet 70,71 can lead to
It crosses and collects the cooling water from separator 101 or 102, pumped with pump 103 and eject water to humid air plate-fin cooler
Mixing water is compensated with the air-flow 106 that enters humid air plate-fin cooler 104 on 104 pipe or by other means.
Based on environmental condition and by fan associated with humid air plate-fin cooler 104 convey actual air flow velocity, by
The water energy of 103 pumping of pump is enough enough to be saturated the air stream of humid air plate-fin cooler 104 and reaches its wet bulb temperature
Degree.The available superfluous water flow from separator 101,102 can be used for other purposes, or may not be enough to sky
