Description

Marine waterproof exhaust system

Technical Field

The invention belongs to the technical field of ship ventilation, and particularly relates to a marine waterproof exhaust system.

Background

The air exhaust device is an important device for controlling a ventilation system in an atmospheric environment.

As shown in fig. 1, the main components of a conventional air grille commonly used in a ship at present are a frame 100, a rat guard 200, fixed louvers 300 and water bars 400.

Such conventional air grilles would be a significant threat to ships that are often exposed to heavy rain or high wind and wave conditions for long-term ocean missions, for four reasons:

1. although the exhaust fan is arranged on the exhaust pipeline to continuously exhaust air from the cabin to the outside, under the condition of heavy rain or heavy wind and wave, the conventional air grid designed at present cannot be completely waterproof, only can block sporadic light rain, and even if the air grid with the wind and rain preventing function is installed, rainwater or wave filled into the windward side of the ship during high-speed navigation cannot be effectively blocked.

2. When rainwater or wave is poured into the air exhaust trap, even if the bottom of the air exhaust trap is provided with the drainage hole, once the rainwater or wave is large enough to cause the drainage hole to be short of draining, a large part of water is difficult to be poured into the air exhaust machine positioned in the bottom cabin along the air exhaust pipeline.

3. Although the bottom of the exhaust fan is also provided with a drain plug screw, the field operator is required to frequently run through the exhaust fan to turn off the exhaust fan and unscrew the plug screw, and hold a washbasin to receive water. Once the water is not drained in time, the rain water or the wave flowers continuously poured in are continuously poured into the motor part of the exhaust fan, a circuit short circuit is formed, and the motor is burnt.

4. In order to avoid damaging the exhaust fan by rain or wave, the manual airtight butterfly valve on the exhaust pipe is closed in rainy days or heavy stormy waves. In order to effectively prevent the water bloom from flowing backwards, some ship exhaust enclosing wells are also provided with pneumatic exhaust closing devices. Under the closing measures, rainwater or wave cannot enter, but by means of the mode of closing the air outlet, not only the exhaust fan cannot be used, but also the corresponding air conditioner is stopped. Therefore, the cabin environment cannot be improved, the comfort of personnel is greatly reduced, and the personnel feel unbearable particularly in sultry and humid yellow plum weather, so that the work and rest of the personnel are seriously influenced.

The structure of the rainproof louver leads the rainproof capacity and the ventilation capacity of the air outlet to be mutually restricted, and when the blades of the rainproof louver are arranged more densely, the rainproof louver has larger resistance to the wind exhausted by the air exhaust pipe, thus influencing the ventilation effect; when the blade setting of rain-proof tripe is comparatively sparse, the waterproof ability of rain-proof tripe is not enough, can't satisfy current exhaust device's demand. Therefore, how to combine ventilation capability and rainproof capability is a problem to be solved urgently at present.
