Description
Technical field
The present invention relates to underwater cleaning technical field, specially a kind of submerged jet cleaning technique of steam input type.
Background technique
With the development of marine economy, the oceans such as offshore oil structure, coastal engineering, sea fishery facility, ships that transport
It is more and more to equip facility.Marine growth is abundant in ocean, long period of soaking equipment in the seawater and ship can by sea organism attachment,
It causes incrustation to be invaded for a long time, brings major safety risks, seriously affect its security performance and service life, suffer great warp
Ji loss.Such as: for ship by marine growth slight adhesion, normaling cruise can increase oil consumption 15% under speed, a severe growth sea
The ship of biology can make oil consumption increase by 2~3 times.
Ocean cleaning at present mainly uses mechanical cleaning and Cleaning by High Pressure Water Jet.Mechanical cleaning low efficiency, high-pressure water shot
Stream cleaning is then along with the thorough destruction to erosion resistant coating, there are security risk, and it is at high cost.Cavitation jet water currently on the market
The lower conventionally used water pressure of cleaning equipment is relatively high, has quite high requirement, equipment making cost to high-pressure pump and equipment pipeline
High, quality weight, volume are big, especially operation at sea when operating condition it is complicated, it is inconvenient, should not place, be not yet received widely available
Using.
For marine ship and and the cleaning of marine settings facility be whole world urgent problem to be solved, have huge market
Development potentiality.
Summary of the invention
The purpose of the present invention is to provide a kind of submerged jet cleaning technique of steam input type, this mode can be improved and compared with
Cleaning efficiency is controlled well, the processing and fabricating requirement of equipment is reduced, preferably controls the volume size and weight of equipment, realization is set
Standby small, light reduces cost, widely promotes and applies.
To achieve the above object, The technical solution adopted by the invention is as follows: a kind of submerged jet of steam input type cleans
Technology makes to flood in water stream containing a large amount of highdensity steam bubbles come to underwater structure progress jet stream using steam input method
Cleaning；The technical program embodiment includes pressure pump, steam generator, jet mixer, the pressure pump by water-supply-pipe with
The water inlet of jet mixer connects, and the steam generator is connected by the air inlet of steam pipeline and jet mixer.
Preferably, the steam pipeline need to select excellent heat-insulating heat-preserving material processing and fabricating.
Preferably, the pressure pump need to select its flow and pressure and other parameters according to specifically used working condition.
Preferably, the jet mixer need to adjust its planform and size according to specifically used working condition.
Detailed description of the invention
Fig. 1 is principle schematic diagram of the invention；
In figure: 1- pressure pump, 2- water-supply-pipe, 3- steam generator, 4- steam pipeline, 5- jet mixer.
Specific embodiment
Below in conjunction with attached drawing 1, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that institute
The embodiment of description is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the technology of the present invention embodiment party
The embodiment of case, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution: a kind of submerged jet cleaning technique of steam input type, packet
Include pressure pump 1, steam generator 3, jet mixer 5；The pressure pump 1 passes through the water inlet of water-supply-pipe 2 and jet mixer 5
Connection；The steam generator 3 is connect by steam pipeline 4 with the air inlet of jet mixer 5；The steam pipeline 4
Excellent heat-insulating heat-preserving material processing and fabricating need to be selected；The pressure pump need to be selected according to specifically used working condition its flow and
Pressure and other parameters；The jet mixer need to adjust its planform and size according to specifically used working condition.
Working principle: cavitation jet is the saturation due to the local depression in liquid fluid system lower than the liquid under relevant temperature
Grow microbubble caused by liquid evaporation vaporization (or being gas core) explosively, when environmental stress is higher than phase
When saturated vapor pressure at a temperature of answering, cavitation bubble is crumbled and fall, and short space generates thermal extremes, high pressure, while companion around bubble
With physical reactions, the chemical reaction for generating complexity, mechanism, electrochemical action and heat effect.Cavitation jet underwater cleaning skill
Art is artificially to make to generate high density cavitation bubble in the water stream by cavitating nozzle by parameters such as control pressure, flow velocitys, empty
Bubble is crumbled and fall in tiny area on the surface of the material generates powerful microjet impact force, and reaches the hard dirt of cleaning and attachment
The purpose of marine growth, research shows that the size of the size of steam bubble size, quantity and confining pressure is directly proportional to jet flow cleaning effect.
Based on cavitation jet and cavitation jet underwater cleaning technical principle, submerged jets Shu Zhonghan is made using steam input method
There are a large amount of highdensity steam bubbles then to can effectively improve the cleaning rate and effect of jet stream.Under the action of pressure pump 1, have
The water stream of certain pressure flows through water-supply-pipe 2 and is sprayed by the nozzle at high speeds of jet mixer 5, and the pressure energy of water is converted into dynamic
Can, negative pressure is formed in induction chamber, steam is sucked, the gas-liquid mixed two-phase mixture of steam and water is constituted, flows through trunnion and diffuser
It injects in water, when steam bubble moves near the surface of solids with water jet, submerged jets form one layer of transverse direction in the surface of solids and overflow
Stream, during moving to the surface of solids, near surface side is basically unchanged steam bubble at a distance from the surface of solids, ignores liquid
The influence of viscosity, steam bubble are to keep the conservation of momentum, it is necessary to it accelerates, remote surface side is inwardly recessed, close near surface side,
Therefore steam bubble is pierced to be formed is directed toward the strong microjet of the surface of solids, high speed, destructive power, and a large amount of steam bubble is in object table
The small regional area in face, which is crumbled and fall, generates powerful microjet impact force to reach the mesh for cleaning hard dirt and attachment marine growth
's.
While there has been shown and described that the embodiment in technical solution of the present invention, for those of ordinary skill in the art
For, it is possible to understand that a variety of variations, modification, replacement can be carried out to it without departing from the principles and spirit of the present invention
And modification, the scope of the present invention is defined by the appended.
