Description

Technical Field

[0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a ventilation system for an ice-covered ship and a ship. Background Art

[0002] At present, for ships in ice areas, the cabin ambient temperature requirement is also 45°C. In order to meet the requirements, the cabin ventilation system needs to consider special design. Usually, heaters are installed in the pipes, and return air vents are designed in the cabin to increase the air temperature.

[0003] Disadvantages of existing technology:

[0004] 1. The shutter inlet is not equipped with an anti-icing and defogger device. Under the influence of the low-temperature external air, the humid air inside the cabin quickly turns into frost, blocking the air intake efficiency of the shutter, resulting in insufficient fresh air volume in the cabin and affecting the normal combustion of the engine.

[0005] 2. Installing a heater inside the air duct affects the normal ventilation area and makes equipment maintenance inconvenient.

[0006] Therefore, how to provide a ventilation system for ice-covered ships and ships has become a technical problem that urgently needs to be solved in the field. Summary of the invention

[0033] According to a first aspect of the present invention, there is provided a ventilation system for an ice-covered ship, such as Figure 1As shown, it includes an exhaust louver 1, a first heater 2, an air inlet louver 4, a second heater 5, a steam heater 3, a controller 11, a diesel engine 14, an outdoor temperature sensor 12 and an air duct temperature sensor 13. The first heater 2 is installed on the exhaust louver 1; the second heater 5 is installed on the air inlet louver 4; the steam heater 3 is installed in the fan room of the hull 15; the outdoor temperature sensor 12 is installed on the outside of the hull 15 for detecting the outdoor temperature; the air duct temperature sensor 13 is installed on the air duct of the fan room for blowing air, for detecting the temperature of the air duct; the controller is connected to the first heater 2, the second heater 5 and the outdoor temperature sensor 12; the steam heater 3 is connected to the air duct temperature sensor 13; the cabin fan is arranged in the fan room, controlled by the controller, and is used for blowing air.

[0034] In some specific embodiments, as shown in Figure 1, the arrow in the figure indicates the wind direction, and the fan chamber is divided into a right fan chamber 7 and a left fan chamber 9. The right fan chamber 7 and the left fan chamber 9 are respectively arranged on the left and right sides of the hull 15. An air inlet louver 4 and a second heater 5 arranged on the air inlet louver 4 are arranged in the right fan chamber 7, and a steam heater 3 is arranged opposite to the air inlet louver 4 in the right fan chamber 7 at a distance, and a right engine room fan 6 is arranged opposite to the steam heater 3 at a distance. The right engine room fan 6 blows air downward to form a right air duct, and a right air duct temperature sensor 13 is arranged on the right air duct, and the air duct temperature sensor 13 is connected to the steam heater 3 by a cable; the structure of the left fan chamber 9 is the same as that of the right fan chamber 7, and also includes a left engine room fan 16.

[0035] The system also includes a manual return air valve 8, which is arranged in the cabin enclosure of the hull. By manually adjusting the manual return air valve 8 in the cabin enclosure, a part of the hot air in the cabin can be drawn back into the fan room for recirculation, thereby achieving the purpose of increasing the air temperature.

[0036] In some embodiments, the first heater 2 is attached to the outside of the exhaust louver 1; the second heater 5 is attached to the outside of the air inlet louver 4; that is, the original louver is improved by installing a heater on the outside of the original louver for defrosting, snow removal, etc.

[0037] In addition, in some other embodiments, the exhaust shutter 1 and the first heater 2 are an integrated structure, and the first heater 2 is arranged inside the exhaust shutter 1; the air inlet shutter 4 and the second heater 5 are also an integrated structure; the second heater 5 is arranged inside the air inlet shutter 4; shutters with heating function can be purchased directly; the first heater 2 and the second heater 5 are both electric heaters.

[0038] Specifically, the system includes a cable 10, and the first heater 2, the second heater 5 and the outdoor temperature sensor 12 are electrically connected to the controller 11 via the cable 10; of course, wireless connection is also possible, but due to signal problems, cable connection is usually used, which is safer and more reliable.

[0039] When the outdoor temperature is lower than the first preset temperature, the controller 11 starts the first heater 2 and the second heater 5 to heat the exhaust louver 1 and the air inlet louver 4 respectively; when the outdoor temperature is higher than the second preset temperature, the controller 11 controls the first heater 2 and the second heater 5 to cut off the power and stop working; wherein the first preset temperature is 5°C; the second preset temperature is 10°C.

[0040] When the temperature measured by the air duct temperature sensor 13 is lower than the third preset temperature, the steam heater 3 is started for heating; the heat of the steam heater 3 is blown into the entire cabin through the cabin fan; when the temperature measured by the air duct temperature sensor 13 is higher than the third preset temperature, the steam heater stops heating; the third preset temperature is 40°C.

[0041] Working principle:

[0042] 1. The outside of the air inlet louver of the fan room and the exhaust louver of the chimney are equipped with outdoor temperature sensors. When the outdoor temperature is lower than 5℃, the heater is powered on; when the outdoor temperature is higher than 10℃, the heater is powered off and stops working.

[0043] 2. The steam heater in the fan room controls the opening of the steam temperature control valve through a temperature sensor, which can heat the outdoor -25℃ cold air to 5℃.

[0044] 3. By manually adjusting the return air damper in the engine room enclosure, part of the hot air in the engine room is drawn back to the fan room for recirculation, thereby achieving the purpose of increasing the air temperature.

[0045] The above three heating methods are used to meet the cabin ambient temperature requirements.

[0046] According to a second aspect of the present invention, there is provided a ship, comprising the ice-going ship ventilation system according to any one of the first embodiments.

The ice-region ship ventilation system of the present application uses a variety of temperature control methods to increase the air temperature from the source of the air intake, reduce the impact of frost on the air inlet, and then greatly increase the air temperature through secondary preheating to meet the minimum operating temperature requirements of the ice-region equipment. Finally, the air mixing temperature is adjusted to the required appropriate temperature by controlling the return air from the engine room. The automatic control logic is simple and easy to operate, the system is more stable, and the temperature control is precise.

[0048] The above are preferred embodiments of the present invention.
