Ring insulation system.
Background technology
Spitkit, such as guard boat, tugboat, its main engine power are larger and usually more than 1, comparatively its principal dimensions
It is smaller, then main exhaust pipe apart from other equipment or closer to the distance, the gas in usual main exhaust pipe of place (such as cargo tank)
Temperature is 600~700 DEG C.Need to ensure that the watertightness of leg, control main frame are arranged when main exhaust pipe passes through engine casing
The vibration of tracheae, then need to be rigidly connected with leg when mounted, and this can make the high-temperature gas in blast pipe rapidly pass heat
It is delivered on leg, and then to whole cabin radiations heat energy, causes the too high temperature of air in leg and cabin, hidden danger is very big.
It is general in the prior art to be thermally shielded using the following two kinds mode：
(1) blast pipe is made into double-layer tube wall, coolant, the heat-insulated effect of this mode is filled in the gap of double-layer tube wall
Although fruit is very well, have the disadvantage that：1. inconvenience is installed；2. it is not easy to safeguard；3. a set of cooling water recirculation system is increased,
Use cost is high；4. the overall weight of blast pipe is increased,
(2) heat is prevented to cabin by one layer of heat insulation foam is all coated on blast pipe and its leg outer surface for being passed through
Radiated in air, this method has the disadvantage that：1. leg coats the large usage quantity of heat insulation foam, and use cost is high；Although 2.
Heat is prevented to be radiated in cabin air, but temperature on leg is still very high, and pole is formed to coating materials such as paint, dampings
Big damage.

Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is structural representation of the invention；
Fig. 2 is the A of Fig. 1 to schematic diagram.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Referring to the efficient ship leg self-loopa insulation system that Fig. 1 and Fig. 2, the present invention are provided, it is arranged on cabin and encloses
On wall 100 in the perforation of blast pipe 200, it is for carrying out quick heat radiating through the blast pipe 200 of perforation, it to include following
Endless tube road 300.
Circulation line 300, it is arranged in perforation, and its integral thickness, less than the thickness of perforation, it is integrally located at wears
In hole.
Sealing welding is specifically used between circulation line 300 and perforation, circulation line 300 is specially a seamless steel pipe, its
Specially open annular shape jaggy, and breach is towards outside engine casing, its interior diameter of a circle and the corresponding matching of blast pipe 200,
Blast pipe 200 may pass through the inner circle of circulation line 300, and circulation line 300 can radiate to blast pipe 200.
The one end of circulation line 300 is outward extended with outlet pipe 310, and the other end is outward extended with water inlet pipe 320, and intakes
The mouth of pipe of pipe 320 is located at underwater and towards the fore direction of ship, and the mouth of pipe of outlet pipe 310 is located at more than waterline and direction
The stern direction of ship.
So, when ship in motion, because water inlet pipe 320 is located at fore direction, and positioned at underwater, lake water or sea
Water can be flowed into circulation line 300 by water inlet pipe 320.
Further, since ship in motion can be to provide the water in water inlet pipe 320 pressure so that enter into circulation
Water in pipeline 300 can be soon flowed into outlet pipe 310.
It is reverse with the traveling of ship conversely, ship in motion will not due to outlet pipe 310 towards the stern direction of ship
Giving the generation pressure of outlet pipe 310, the water being flowed into outlet pipe 310 can discharge at once.
In addition, in order to prevent water from being flowed into from outlet pipe 310, therefore outlet pipe 310 is arranged in waterline by the application
More than.
Water efficiency is changed in order to improve circulation line 300, so as to improve radiating efficiency, water inlet pipe 320 has with outlet pipe 310
Body is all Z-shaped.
By above-mentioned implementation, when ship running, the water in circulation line 300 can constantly be circulated, thus can be by
Heat on blast pipe 200 is constantly taken away by the water in circulation line 300, so as to carry out fast cooling to blast pipe 200.
Because circulation line 300 is located between leg 100 and blast pipe 200, and the water in circulation line 300 does not stop
Logical, the heat on such blast pipe 200 is not transmitted on leg 100, so as to the temperature that ensure that on leg 100 will not rise
Height, substantially increases security.
Further, since the water in the sea or in river is continually, the application in the case of not by other plant equipment, only
Blast pipe 200 can be radiated by the cooperation between circulation line 300 and outlet pipe 310 and water inlet pipe 320, dropped significantly
Low use cost, and also a saving resource.
Furthermore, the speed of its traveling is faster due to ship in motion, and the heat that blast pipe 200 is produced will be bigger, and
, in water inlet, the speed of ship running is faster, and its water intake velocity also can be faster, so that following for water inlet pipe 320 in the application
The water speed that changes on endless tube road 300 also can be faster, and the radiating efficiency of circulation line 300 also can be better.
In order to further improve the radiating efficiency of the application, the application also includes a heat-proof device 400, heat-proof device 400
It is specifically located between circulation line 300 and blast pipe 200, it can absorb to the heat that blast pipe 200 is produced, and will be surplus
Remaining heat transfer is to circulation line 300.
Heat-proof device 400 is specially circular heat insulation foam, its interior circular diameter and the corresponding matching of blast pipe 200, heat-insulated dress
The outer surface that can be closely coated on blast pipe 200, its outside diameter and the interior circular diameter corresponding matching of circulation line 300 are put, is followed
Endless tube road 300 can be fitted tightly on the outer surface of heat-proof device 200.
In addition, by the setting of heat-proof device 400, prevented also from ship when rocking so that blast pipe 200 and circulation pipe
The damaged in collision of road 300.
General principle of the invention and principal character and advantages of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not limited to the above embodiments, simply explanation described in above-described embodiment and specification this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appending claims and its
Equivalent thereof.
