Problems solved by technology
In a ship, the power part of the engine room, which is the "heart" of the ship, should meet the highest level of safety protection requirements. However, in actual implementation, because other equipment in the engine room does not meet the conditions or parameters required by this protection level, it can only be obtained from other channels. To meet the requirements of cabin security

The invention discloses a ventilation device of a methanol fuel propelled marine engine room, and aims to provide the ventilation device which can be used safely and discharge methanol. The device comprises an air inlet channel and an air outlet channel, the air inlet channel and the air outlet channel are both vertically arranged and both penetrate through a cabin top plate, a first air inlet isformed in the upper end of the air inlet channel; the first air inlet is positioned outside a cabin; a first exhaust fan is arranged on the first air inlet in a matched manner; a first air outlet is formed in the lower end of the air inlet channel; the first air outlet is located in the middle of the interior of the cabin, the upper end of the air outlet channel is provided with a second air outlet, the second air outlet is located outside the cabin, the lower end of the air outlet channel is provided with a second air inlet, the second air inlet is close to the bottom of the interior of the cabin, and the second air inlet is provided with a second exhaust fan in a matched mode. The invention is applied to the technical field of ventilation devices.
Description
technical field [0001] The invention relates to a ventilation device, in particular to a ventilation device for a methanol fuel propulsion ship engine room. Background technique [0002] On ships transporting methanol or ships using methanol as fuel for marine engines, due to the low flash point, flammability and explosive characteristics of methanol, full safety precautions must be taken to prevent tanks containing methanol from entering the air. Explosion occurs in flammable concentrations. In a ship, the power part of the engine room, which is the "heart" of the ship, should meet the highest level of safety protection requirements. However, in actual implementation, because other equipment in the engine room does not meet the conditions or parameters required by this protection level, it can only be obtained from other channels. To meet the requirements of cabin security. One of them is to use the ventilation of the engine room to remove the methanol vapor in the engine...
