A ship ventilation system

Abstract

The invention provides a ventilation system for a ship, which includes a ventilator with an inner tuyere and an outer tuyere, the inner tuyere of the ventilator is connected with a main ventilation pipe, and the main ventilation pipe is provided with ventilation branch pipes communicating with each cabin respectively , the end air outlet of the ventilation branch pipe is located in the corresponding cabin, and the end air outlet of the ventilation branch pipe is provided with an axial flow fan and an electric heating network, and the axial flow fan and the electric heating network are electrically connected with the control panel. By adjusting the inner axis of each ventilation branch pipe The position of the air flow fan is used to adjust the air volume entering the corresponding cabin to meet the ventilation needs of different cabins; and the setting of the electric heating network can heat the wind in the corresponding ventilation branch pipe to meet the heat preservation needs of some cabins and avoid people in the cabin. The goods are frozen.

Description

technical field [0001] The invention belongs to the technical field of ventilation systems, and in particular relates to a ship ventilation system. Background technique [0002] The current ship ventilation system is divided into natural ventilation and mechanical ventilation. Due to the large resistance along the air duct, the natural ventilation without pressure often cannot achieve a good air intake and exhaust effect, and can only achieve the effect of balancing the cabin air pressure; Although the mechanical ventilation is equipped with a large fan for the air intake and exhaust of each cabin, the air volume of the vent near the large fan is large, and the air volume of the vent far away from the large fan is small, which cannot meet the ventilation of different cabins Require. [0003] In addition, with the large-scale development of ships, the electricity required for daily work and life of the crew continues to increase. If we continue to rely on burning non-renewab...

Problems solved by technology

[0002] The current ship ventilation system is divided into natural ventilation and mechanical ventilation. Due to the large resistance along the air duct, the natural ventilation without pressure often cannot achieve a good air intake and exhaust effect, and can only achieve the effect of balancing the cabin air pressure; Although the mechanical ventilation is equipped with a large fan for the air intake and exhaust of each cabin, the air volume of the vent near the large fan is large, and the air volume of the vent far away from the large fan is small, which cannot meet the ventilation of different cabins Require

[0003] In addition, with the large-scale development of ships, the electricity required for daily work and life of the crew continues to increase. If we continue to rely on burning non-renewable energy to obtain electricity, it will not only emit a large amount of pollutants, but also accelerate the depletion of non-renewable energy. The light is strong, inexhaustible, if not utilized, it will be a great loss

[0004] Furthermore, sea conditions are changing, and severe weather that occurs rapidly (that is, has a short life history) is prone to occur, such as storms, typhoons, etc. If these severe weather are not predicted in time and measures are taken, it will greatly affect the safety of maritime navigation. threaten
