Description

The dirigible condensed water collecting device

Technical field

The utility model relates to dirigible and large-scale load-carrying dirigible field when high and medium is long to navigate, and relates in particular to a kind of dirigible condensed water collecting device.

Background technology

At present, the high and medium dirigible generally adopts the aviation power driving engine, and along with the consumption gradually of fuel oil, it is more and more lighter that the weight of dirigible will become, and dirigible buoyancy will be greater than dirigible gravity, and dirigible can not keep its set flying height and rise gradually.Dirigible owing to there is bigger net buoyancy, will cause very difficulty of dirigible landing in decline land process.Dirigible and large-scale load-carrying dirigible during especially for the long boat of high and medium, the fuel oil that carries reaches more than several tons, and it is more outstanding that gravity buoyant equilibrium control problem will become.Therefore, how to solve the balance control technology between the suffered gravity and buoyancy in the process that dirigible constantly changes along with its flying height of fuel oil consumption in flight course, be one and be badly in need of the gordian technique that solves.

At present, the gravity buoyant equilibrium mode of high and medium dirigible has: 1, engine thrust vector balancing; 2, dynamic lift balance; 3, complete electric dirigible designing technique; 4, put helium balance control mode.

1, engine thrust vector balancing, its weak point are that fuel oil consumption is many more, and the gravity losses that causes is also big more, need bigger engine thrust to come these gravity losseses of balance again, consume more fuel oil then.So like this vicious circle is gone down, and finally makes dirigible pay bigger weight cost, economic cost, and the fuel oil of additive decrementation too much even can have influence on the completion of aerial mission.

2, dynamic lift balance, its weak point be to add the weight of gas compressing apparatus with present material science level, and a whole set of helium recovery device can increase weight bigger, and for dirigible, the big like this device that must increase weight is impracticable at present.

3, complete electric dirigible designing technique; At present domesticly complete electric dirigible designing technique has been carried out good try; But owing to receive the yoke of current solar cell, hydrogen helium storage battery and electrical motor developing water article, large-scale complete electric dirigible designing technique can only rest on the aspect of theoretical demonstration or preliminary test checking at present.

4, putting helium balance control mode, is a kind of efficient and simple method though its weak point is to put the helium balance, and this method can only be as a kind of emergent means, considers from economic aspect, can not be as a kind of measure of long-term use.

The utility model content

The purpose of the utility model is exactly the deficiency to the gravity buoyant equilibrium mode of present above-mentioned high and medium dirigible, and a kind of dirigible condensed water collecting device is provided.

The utility model is made up of driving engine, motor exhaust freeing pipe, heat exchanger, air water separator and water tank; The engine exhaust emission mouth communicates with the admission port of heat exchanger through the motor exhaust freeing pipe; Be respectively equipped with A valve and B valve on the motor exhaust freeing pipe; The condensed water import of air water separator and condensation-water drain communicate with the condensation-water drain of heat exchanger and the condensed water import of water tank respectively, are respectively equipped with blowdown valve and guard valve on the water tank.

The utility model has the advantages that: this condensed water collecting device can effectively be realized the collection of aqueous vapor in the centering HAA motor exhaust, can also play the ballast effect simultaneously, thus protection dirigible safety.

Fig. 1 is the utility model structural representation.

The specific embodiment

As shown in Figure 1; The utility model is made up of driving engine 1, motor exhaust freeing pipe 2, heat exchanger 3, air water separator 4 and water tank 5; Driving engine 1 exhaust port communicates through the admission port of motor exhaust freeing pipe 2 with heat exchanger 3; Be respectively equipped with A valve 2-1 and B valve 2-2 on the motor exhaust freeing pipe 2; The condensed water import of air water separator 4 and condensation-water drain communicate with the condensation-water drain of heat exchanger 3 and the condensed water import of water tank 5 respectively, are respectively equipped with blowdown valve 5-1 and guard valve 5-2 on the water tank 5.

Principle of work: before the use, this device is installed on the dirigible, when dirigible take off or process such as landing in; Driving engine 1 demand motive force is bigger; Need efficient discharge motor exhaust, at this moment Open valve 2-2 in order to satisfy the dirigible power demand this moment; Valve-off 2-1, driving engine 1 tail gas are directly through valve 2-2 exhaust to atmosphere.In the middle of cruise during the long boat of HAA or the operational process of fixing a point in, for the balance great amount of fuel oil consumes caused net buoyancy, in can be in this process to motor exhaust aqueous vapor is collected; Open valve 2-1, valve-off 2-2, this moment, driving engine 1 tail gas got into heat exchanger 3 through motor exhaust freeing pipe 2; Through with the cold air heat exchange; Most of water vapor condensation is come out,, realize that condensation goes out to such an extent that water separates with residual exhaust simultaneously through air water separator 4; The water that condensation goes out then gets in the water tank 5, thereby realizes the collection of condensed water.In the process of collecting condensed water; In the time of heat exchanger or other fault also might occurring and cause motor exhaust to discharge, the pressure in the motor exhaust freeing pipe increases, and needs the urgent tail gas that discharges; This moment, but Open valve 2-2 discharged tail gas, thereby avoided occurring dangerous.Water collecting is flowing in the process of water tank; Gaseous tension in the water tank can increase, and can influence the collection of condensed water, and this moment need be to carrying out row pressure in the water tank; When pressure reaches certain value; Blowdown valve 5-1 self-opening discharges the inner unnecessary gaseous tension of water tank, thereby helps the collection of condensed water.In addition, when dirigible runs into emergency condition and needs expendable weight to reduce descending speed, can open the water that guard valve 5-2 discharges appetite and alleviate the weight of dirigible, thereby reduce the speed that dirigible descends, protection dirigible safety.
