Abstract
The invention discloses a cavitation bubble oxygen production technology for a submarine. The technology comprises a propeller, a propeller cover and a spindle and is technologically characterized in that absorption holes which can absorb cavitation foams generated by the propeller are formed in the whole inner wall of the propeller cover; and the absorption holes are connected to an oxygen collection device in the submarine via a gas collecting tube. The technology disclosed by the invention has the advantages that oxygen can be produced "for free" during a voyage, so that consumption of sodium carbonate and oxygen generated from the reaction between sodium peroxide (Na2O2) solids or potassium superoxide solids and carbon dioxide can be greatly reduced; the use cost for the oxygen can be greatly reduced; generation and disposal of pollutants or wastes can be reduced; and thus burdens can be alleviated and effective use space can be left for the submarine.
Description
Technical field
The present invention relates to a kind of submarine oxygenerating technology, particularly a kind of cavity oxygenerating technology for submarine.
Background technology
The oxygen of submarine is mainly from four aspects: submarine snorkel, aircondition, air regeneration unitAnd air cleaning unit.
Submarine snorkel is a kind of pipe that can lifting, and in offshore sea waters or when navigation at night, submarine hasTime float up to periscope depth, stretching out the periscopic vision water surface apart from several meters of the waters surface or tens meters of dark placesAnd aerial enemy's situation, as conditions permit, breather pipe can be risen to the water surface, air enters submarine cabin through pipe,In cabin, foul atmosphere can be discharged by the exhaust pipe device air exhauster that is located at fairwater rear portion, makes shipInner air convection, can keep fresh air. Periscope depth is called dangerous depth in tactics term,For the purpose of hidden, submarine generally all dare not use this duty, because it is very easily by the antisubmarine soldier of enemyPower is found, also easily clashes into or confuse fishing net etc. in coastal waters.
Aircondition is mainly temperature, the humidity etc. keeping in ship, makes ship person have a comfortable life cycleBorder and condition of work ensure the normal work of electronic equipment simultaneously, and itself can not produce oxygen.
Air regeneration unit is a kind of device that can generate oxygen, it by the blower fan of regenerating, oxygenerator,The compositions such as absorption unit of dioxide carbon. When work, blower fan is evacuated to dioxy by air dirty in cabin through airductChange carbon absorption plant, eliminate carbon dioxide, then in the air of processing, add and produced by oxygeneratorOxygen, then delivers to each cabin through airduct and breathes for ship person, and so circulation, to reach the object of air regenesis.This air regeneration unit also can carry out oxygen with brine electrolysis conventionally, and the oxygen that it decomposites can be for 70～100People's Respiration Rate hour, but because power consumption is too much, be unsuitable for conventional submarine. In addition, also have some pre-storage oxygenThe method of gas, as regeneration medicine plate, oxygen cylinder, liquid oxygen and oxygen candle etc. Regeneration medicine plate is a kind of by variousThe porous plate that chemical substance and filler are made, air stream is out-of-date, just can produce chemical reaction, generates oxygen.On general submarine with regeneration medicine plate, can use 500～1500 hours. Oxygen cylinder is that oxygen is storedA kind of high-pressure bottle, when use, open valve and can exit, mainly for diving bell, bathyscaph etc.Liquid oxygen is also a kind of and the similar high-pressure bottle of oxygen cylinder, and it can be for 100 ship persons 90 days.Oxygen candle is a kind of candle shape combustible of being made up of chemical material etc., after lighting, can make oxygen. 1 chi is long,The oxygen that diameter the is 3 cun oxygen of emitting of lighting up, can breathe 1 hour for 40 people.
Air cleaning unit is that airborne pernicious gas and Control of Impurities in ship are being allowed below standard valueA kind for the treatment of apparatus, conventional has following four kinds: the one, the hydrogen burning device that disappears, it is mainly that electricity consumption addsHot device is heated the air flowing through, and then under the catalytic action of catalytic combustion bed, makes hydrogen, oxygen that chemistry occursReaction and generate steam, hydrogen with regard to burned fall. The 2nd, harmful gas burner, its working methodBasic identical with the first, what only it burnt is pernicious gas. The 3rd, purifying carbon dioxide dressPut, it carrys out absorbing carbon dioxide by the special liquid of one. The 4th, active carbon filter, it is with activeCharcoal is made filtrate, and the porous adsorbent being made up of special charcoal absorbs various pernicious gases, Jin ErdaTo the object purifying air.
No matter in sum, be not difficult to find out, be any method for producing oxygen through, all needs to pay certain cost,And the cost of this cost is high often.
Summary of the invention
Task of the present invention is to propose a kind of cavity oxygenerating technology for submarine, to reduce ship with oxygenUse cost.
From hydrodynamics, in the time of current pile warp blade, on suction surface, its local velocity will be largeIn intact water velocity; On blade thrust face, its speed of streaming will be less than intact speed. RootCan derive pressure on the blade suction surface water flow pressure when being less than end and disturbing according to bernoulli's equation,In the time that the rotating speed of screw is increased to certain certain value, the Pressure Drop at the Peak Flow Rate place on the suction surface of bladeWhile arriving the saturated vapour pressure at this place's temperature, on suction surface, just there will be cavity. Along with screw turnsThe pseudo-continuation of speed improved, and cavity region can be expanded whole leaf unit suction surface gradually to, the sky of Here it is screwChange the origin cause of formation of the generation of phenomenon and cavity.
Because the air pressure in cavity is very low, thereby the oxygen dissolving in seawater can be discharged rapidly (thisAlso be the reason place why cavity can corrode screw). So far, the present invention is achieved in that
For a cavity oxygenerating technology for submarine, comprise screw, oar cover and rotating shaft, its technical charactericticBe: the inwall of oar cover is covered with the sucker that can absorb the cavity air foam that screw produces, and sucker is by collectionTracheae connects oxygen collecting device in ship.
Advantage of the present invention: " freely " oxygen producing under sail, greatly reduces and utilize sodium peroxide(Na2O2) solid or potassium superoxide solid and carbon dioxide reaction generate sodium carbonate and oxygen, not only canSignificantly reduce the use cost of oxygen, but also can reduce generation and the cleaning of pollutant or discarded object, fromAnd be that submarine is lightened the burden and vacates effective usage space.
Embodiment
