The invention discloses a deicing device for a pile leg of an offshore work platform, which belongs to the field of offshore engineering equipment. The deicing device for the pile leg of the offshore work platform comprises pile legs, water spray tubes, a water injection zone, a gas inlet tube, a heat radiating tube, a gas outlet tube, a floating body block, a gas outlet zone, a gas inlet zone and a water inlet tube, wherein the floating body block, the gas outlet zone, the gas inlet zone and the water inlet zone are sequentially sleeved on the sidewall of each pile leg, the gas outlet zone and the gas inlet zone are installed together via the heat radiating tube and form a passage for interior gas, and the gas outlet tube and the gas inlet tube are respectively installed on the gas outlet zone and the gas inlet zone; the water injection zone is installed on the upper part of the gas inlet zone, and the water spray tubes are uniformly distributed on the water injection zone; and the gas inlet tube is connected with a tail gas tube of a diesel engine, and the water inlet tube is connected with hot water drained by the diesel engine. The floating body block, the gas outlet zone, the water injection zone and the gas inlet zone are respectively annular, and the interiors of the floating body block, the gas outlet zone, the water injection zone and the gas inlet zone are hollow bodies; and the floating body block, the gas outlet zone, the gas inlet zone and the water injection zone are in clearance fit with the sidewall of each pile leg, and can move on the pile leg. The device deices the pile leg by using waste heat of the diesel engine unit of the offshore work platform, thus eliminating the ice load of the pile leg, and greatly increasing the service life of the pile leg in severe cold regions.
Description
Technical field
The present invention relates to a kind of maritime platform, is mainly a kind of maritime platform spud leg thawing apparatus, belongs to offshore engineering equipment field.
Background technology
Along with economic fast development, people start to ask for the energy to ocean, a large amount of maritime platforms is put in marine petroleum exploitation, but in some high latitude areas, freezing serious, can bring very large load to platform leg, time one length will be broken or damage, and is a urgent problem at present.
Summary of the invention
The object of this invention is to provide a kind of maritime platform spud leg thawing apparatus.
The problem to be solved in the present invention is that existing maritime platform spud leg runs into the deficiency that freezing meeting fractures spud leg or damages.
For realizing object of the present invention, the technical solution used in the present invention is:
Maritime platform spud leg thawing apparatus, comprise spud leg, sparge pipe, water filling band, air inlet pipe, radiating tube, escape pipe, buoyancy aid piece, go out the band of gas, air inlet band and water inlet pipe, on spud leg sidewall successively cover have buoyancy aid piece, go out the band of gas, air inlet band and water filling band, go out the band of gas and air inlet band were installed together and were formed internal gas path by radiating tube, go out on the band of gas and air inlet band and be separately installed with escape pipe and air inlet pipe; Air inlet band top is provided with water filling band, on water filling band, is evenly equipped with sparge pipe; Air inlet pipe connects diesel engine vent gas pipe, and water inlet pipe connects the hot water that diesel engine is discharged.
Buoyancy aid piece, go out the band of gas, water filling band and air inlet band all circlewise, inside is hollow body, and material is stainless steel; Spud leg sidewall and buoyancy aid piece, go out the band of gas, air inlet band and water filling band and be matched in clearance, can on spud leg, move; On water filling band, be evenly equipped with 20 sparge pipes; Go out the band of gas and air inlet band and be evenly equipped with 20 radiating tubes; The buoyancy that buoyancy aid piece produces is 1.3-1.5 times of whole installation weight.
Advantage of the present invention is: this device utilizes the waste heat of maritime platform diesel engine unit to carry out, to spud leg ice, having eliminated the ice load of spud leg, has greatly improved the application life of spud leg in severe cold area, and energy-conserving and environment-protective, should have the wide market space.
Brief description of the drawings
Fig. 1 is the stereogram of maritime platform spud leg thawing apparatus of the present invention;
In figure: 1, spud leg 2, sparge pipe 3, water filling band 4, air inlet pipe 5, radiating tube 6, escape pipe 7, buoyancy aid piece 8, go out the band of gas 9, air inlet band 10, water inlet pipe.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in the figure, maritime platform spud leg thawing apparatus, comprise spud leg 1, sparge pipe 2, water filling band 3, air inlet pipe 4, radiating tube 5, escape pipe 6, buoyancy aid piece 7, go out the band of gas 8, air inlet band 9 and water inlet pipe 10, on spud leg 1 sidewall successively cover have buoyancy aid piece 7, go out the band of gas 8, air inlet band 9 and water filling band 3, go out the band of gas 8 and air inlet band 9 were installed together and were formed internal gas path by radiating tube 5, go out and on the band of gas 8 and air inlet band 9, be separately installed with escape pipe 6 and air inlet pipe 4; Air inlet band 9 tops are provided with water filling band 3, are evenly equipped with sparge pipe 2 on water filling band 3, for ice face is sprayed to hot water ice; Air inlet pipe 4 connects diesel engine vent gas pipe, and water inlet pipe 10 connects the hot water that diesel engine is discharged.
Buoyancy aid piece 7, go out the band of gas 8, water filling band 3 and air inlet band 9 all circlewise, inside is hollow body, and material is stainless steel; Spud leg 1 sidewall and buoyancy aid piece 7, go out the band of gas 8, air inlet band 9 and water filling band 3 and be matched in clearance, can on spud leg 1, move; On water filling band 3, be evenly equipped with 20 sparge pipes 2; Go out the band of gas 8 and air inlet band 9 and be evenly equipped with 20 radiating tubes 5; The buoyancy that buoyancy aid piece 7 produces is 1.3 times of whole installation weight, and radiating tube 5 generally just in time contacts with ice face like this, increasingization ice effect, 15 ° of sparge pipe 2 inclination vertical directions.
The using method of this device: this device is enclosed within on spud leg 1, to the interior water filling of buoyancy aid piece 7, adjust its buoyancy, then with high-pressure hose, air inlet pipe 4 is connect to diesel engine vent gas pipe, water inlet pipe 10 connects the hot water that diesel engine is discharged, and whole like this device is with seawater the tide is flowing and ebbing, waste gas enters after air inlet band 9 by radiating tube 5 heat radiationization ice, hot water by sparge pipe 2 ejection after evolutionizations ice, so just can not the ice formed and energy-saving effect is quite remarkable on spud leg 1, and simple and practical; This device also can be made hinge arrangement form, just can install or unload after opening in two hinge, facilitates its picking and placeing on spud leg.
