Description
Technical field
The present invention relates to technical field of ships, in particular to a kind of ship fresh-water tank winterization system.
Background technique
The ship of ice navigation needs to apply that symbol is reinforced in ice formation, and classification society requires to reinforce with ice formation the ship of symbol to top
Portion is higher than waterline and the fresh-water tank adjacent with outside plate should be equipped with antifreezing measures.
Common fresh-water tank antifreezing measures have following two:
1, it is passed through compressed air in cabin to froth, the water in cabin is made to generate disturbance.In bilge portion, compressed air is set
Pipe, managing every 2-3m setting diameter is about the hole 3mm.By being passed through compressed air toward cabin inner tube, bubble is generated.By bubble from
The bilge process that the water surface rises in cabin, so that the water in cabin is generated disturbance prevents from freezing.
The disadvantage is that: 1. compressed air is mixed with a small amount of oil gas and impurity, can pollute water quality.2. heating and thermal insulation effect is unknown
It is aobvious, it is not applicable in extreme severe cold area.
2, heating coil is arranged in fresh-water tank, is passed through steam or hot oil is heated.
The disadvantage is that: 1. pollute water quality to prevent coil pipe from getting rusty, the heating coil in fresh-water tank be generally stainless steel or
Copper, construction cost is high, and still has the phenomenon that rust corrosion over time.2. personnel, which need to enter, is laid with coil pipe in fresh-water tank,
Working space is narrow, and working environment is severe, there is certain difficulty of construction.3. holding when carrying out the weld job of coil pipe pipeline support
Epoxy coating in destructible fresh-water tank.4. heating to entire water tank, energy consumption is high.5. heating coil need to be pierced by bulkhead
Heat source is connected, fresh-water tank disclosure risk is increased.6. cannot directly be contacted with domestic fresh water when heat source is hot oil, need elder generation
Fresh water, reusable heat water circulating-heating fresh-water tank in coils, after heat transfer process twice, efficiency of energy utilization are heated with hot oil
It is low.
