Description
Technical field
The present invention relates to the defroster of a kind of ice formation ballast tank of ship, strengthen ship for ice formation, the large-scale merchant ship of grade is strengthened in especially high ice formation.
Background technology
Navigation in ice region boats and ships are in low temperature environment, and if do not taked freezing proof technique, ballast tank maritime interior waters will freeze, and affect ship operation, and cause hull structure to be out of shape.The freezing proof technique of current ice formation ballast tank of ship mainly contains bubble proof, heating, seawater circulation method of perturbation etc.Bubble proof is blowing compressed air bottom ballast tank, utilizes Going-up Movement of Bubbles and to break making ice at the water surface; Heating arranges heating coil in ballast tank, utilizes boiler heat to heat the method for ballast water making ice; Seawater circulation method of perturbation utilizes the ballast water in ballast pump loop ballast cabin, utilizes the method for the disturbance making ice of current.
These three kinds of methods respectively have weak point: bubble proof need arrange more compressed air tube in ballast tank, these small-bore compressed air tubies are disappeared in the seawater throughout the year, corrosion is relatively serious, and for the area of weather and cold thereof, bubble proof can not prevent ballast tank from freezing effectively.Heating arranges heating coil in ballast tank domestic demand, and heating coil steeps in the seawater throughout the year, very easily corrosion, and heating need expend boiler heat, increases boiler capacity.Seawater circulation method can not prevent ballast tank from freezing at pole cold district effectively.
Utility model content
The shortcoming that the object of the invention is to overcome prior art is not enough, on employing ballast tank seawater recirculation perturbation technique basis, utilizes marine mechanical and electrical equipment waste heat ballast water simultaneously, improves ballast water temperature, and when preventing boats and ships navigation in ice region, ballast tank freezes.
For achieving the above object, the utility model adopts following technical proposal:
A defroster for ice formation ballast tank of ship, specifically comprises No. 1 central fresh water cooler, No. 2 central fresh water coolers, No. 1 ballast pump, No. 2 ballast pumps, ballast tank, valve member and ballast water circulation pipings etc.; It is characterized in that: be interconnected to constitute an internal circulation system by ballast water circulation piping between each several part, some valve members are arranged on the appropriate location of ballast water circulation piping;
Described No. 1 central fresh water cooler and No. 2 central fresh water coolers are the cooling vessel that the former design of boats and ships adopts, and be two titanium plate coolers, every platform capacity is 60% of the total heat exchange amount of electromechanical appliance;
Described No. 1 ballast pump and No. 2 ballast pumps are the ballast pump that original system adopts, and a ballast pump can be adopted to run, two ballast pumps also can be adopted simultaneously to run when normal recirculation runs, and increase ballast water circulation perturbation action;
Described ballast tank is ballast tank of ship, and quantity is determined according to boats and ships general requirement;
Described valve member comprises the valve member of some difference in functionalitys, wherein the bypass disc WBV11 of central fresh water cooler is aperture adjustable valve, for the ease of at the whole ballasting system of ballast control desk remote manipulation, this valve can select aperture to indicate remote control butterfly valve, and this valve caliber should be identical with ballasting system exhaust tube caliber;
Described ballast water circulating pipe is native system main portion, and be also the part comparing the increase of conventional ballast water system, this part piping is drawn from ballast pump exhaust tube, after central fresh water cooler, to each ballast tank; The discharge orifice that circulating pipe ties up to ballast tank is arranged in by apical position in the middle part of this cabin, to increase turbulent water effect in ballast tank.
Owing to taking above technical scheme, make the utility model compared with the prior art tool have the following advantages and effect:
One, the technology that this cover system adopts two kinds of antifreeze modes to combine is frozen to prevent ballast tank, realizes dual guarantee.System is relatively more succinct, reasonably utilizes the used heat of cabin electromechanical appliance, can be suitable for boats and ships in comparatively cold district navigation;
Two, system mainly adopts boats and ships existing installation, only increases some pipings and valve member, and the cost of manufacture of system is lower;
What three, arrange in ballast tank is all heavy caliber piping, and piping wall thickness is also thicker, and compare steam heating piping and the piping that froths, resistance to corrosion is stronger;
Four, to while heating ballast water be again boat low-temperature water system cooling.For cooling system, the design of the conventional cooling low temperature water system that drawn water from suction box by sea water pump, a large amount of trash ice that has mixed in suction box can enter salt water cooling system, EVAC (Evacuation Network Computer Model) work, damages sea water pump.And the cooling water expansion tank of the cold system of anhydrating of native system design is from bottom ballast tank, bottom ballast tank, seawater is without any trash ice.Therefore this ballast tank ice protection system, when effectively can solve again navigation in ice region, suction box trash ice is on the impact of cooling water system.
