Technical Field
The invention relates to the technical field of ventilation pipelines, in particular to a ventilation pipeline system for ventilating a cargo hold of a cargo ship.
Background
On a traditional cargo ship, a plurality of ventilation openings are formed in a cover of a cargo hold, and are used for exhausting flammable and explosive dangerous gases generated by dangerous goods such as steam or pulverized coal, iron powder and the like scattered by the cargo hold out of the cargo hold.
Since the ventilation openings of the covers of the cargo compartment are generally of a naturally ventilated grid structure, no corresponding flow-guiding ducts are provided. When the cargo hold is filled with pulverized coal and iron powder, the generated dangerous gas is emitted to the deck of the cargo ship through the vent and is accumulated near the hatch cover, so that safety accidents such as explosion and the like are easily caused. Moreover, the grid type ventilation openings are low in ventilation efficiency, and dangerous gas is easily accumulated in the cargo hold, so that potential safety hazards are generated.
Secondly, because the cabin cover is provided with the vent, during the driving process of the cargo ship, the large wind waves can cause seawater to enter the cargo cabin through the vent, so that the cargo is corroded and the safe driving of the cargo ship is influenced.
Therefore, a ventilation duct system is needed to solve the above problems.
Disclosure of Invention
The invention aims to provide a ventilation pipeline system, so as to avoid the accumulation of dangerous gas and the water inflow of a cargo hold in or out of the cargo hold and improve the ventilation efficiency of the ventilation pipeline system.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a ventilation pipe system installed on a cargo ship, comprising:
the plurality of gas collecting hoods are arranged and are all arranged in a cargo hold of the cargo ship and are respectively communicated with corresponding ventilation openings on the cargo hold;
the main pipeline comprises a horizontal pipeline and a vertical pipeline which are communicated; and
and one end of each branch pipeline is communicated with the corresponding gas collecting hood, and the other end of each branch pipeline is communicated with the horizontal pipeline, so that the gas collecting hoods are communicated with the main pipeline through the corresponding branch pipelines, and a ventilation pipeline is formed.
Preferably, the ventilation pipeline system further comprises an air draft device, and an air draft opening of the air draft device is communicated with the inner cavity of the air collecting hood.
Preferably, the ventilation pipeline system further comprises two air supply devices, wherein one air supply device is communicated with one end, far away from the vertical pipeline, of the horizontal pipeline, and the other air supply device is communicated with the bottom end of the vertical pipeline.
Preferably, the branch pipes are flexibly connected to the corresponding gas collecting hoods.
Preferably, each of the branch pipes is provided with a switch capable of opening or closing the corresponding branch pipe.
Preferably, the outlet end of the vertical pipe is provided with a flow guide sleeve.
Preferably, the outlet end of the vertical pipe is further provided with a gas concentration monitoring device.
Preferably, the height of the vertical pipe is 5 m.
Preferably, the gas collecting channel is a watertight channel.
Preferably, the main pipeline and the branch pipelines are made of glass fiber reinforced plastics.
The invention has the beneficial effects that:
the invention provides a ventilation pipeline system installed on a cargo ship. The gas collecting hood is communicated with the ventilation opening of the cargo hold and collects steam and/or dangerous gas in the cargo hold into the gas collecting hood, so that the ventilation efficiency of the cargo hold is improved. The gas collecting hood, the branch pipelines and the main pipeline are sequentially communicated to form a ventilation pipeline, and steam and/or dangerous gas in the cargo hold are quickly discharged out of the cargo hold. The ventilation efficiency is improved, and danger caused by dangerous gas accumulation is avoided. Moreover, the explosion-proof grade of the deck electrical equipment at the vent of the cargo hold is reduced, so that the purchase cost of the deck electrical equipment is reduced. The vertical pipeline effectively prevents seawater from entering the cargo hold through the ventilation pipeline, and is favorable for safe operation of the cargo ship.
