Marine intake air filtering device

Abstract

The invention discloses a marine intake air filtering device. The marine intake air filtering device comprises a frame assembly, a filtering assembly and an anti-freezing assembly, the frame assembly is of a multi-layer frame body structure, and the filtering assembly comprises a shutter, a weather tight structure, a front inertia level, a net pad level and a rear inertia level which are sequentially mounted in the multi-layer frame body structure from outside to inside; the anti-freezing assembly is installed in the louver and the weather tight structure. The device is simple and stable in structure, rain waves and water mist can be effectively blocked through the front-back combination mode of the louver and the weather tight structure, and solid particles and salt mist can be efficiently filtered and separated through the combination mode of the front inertia level, the net pad level and the rear inertia level; and meanwhile, low-temperature freezing of the device can be prevented through an electric heating mode, the anti-freezing effect is achieved, normal operation can be guaranteed, and meanwhile the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of marine air intake treatment, and more particularly to a marine air intake filter device. Background technique [0002] The air intake quality of ship gas turbines and diesel engines has been affected by the complex marine environment for a long time. The air not only contains a certain amount of solid particles, but also distributes a large number of tiny salt mist water droplets under seawater disturbance and rainfall conditions. The air directly enters the gas turbine and diesel engine without filtering treatment, which not only directly affects the combustion efficiency of fuel, reduces the power output performance of the ship, but also causes continuous corrosion to the metal structure and shortens the normal service life. Therefore, ships are generally equipped with air intake filters. It can filter and separate the intake solid particles and salt mist; however, when the intake filter device is insta...

[0002] The air intake quality of marine gas turbines and diesel engines has long been affected by the complex marine environment. The air not only contains a certain amount of solid particles, but also distributes a large number of tiny salt spray droplets under seawater disturbance and rainfall conditions. If solid particles and salt spray droplets Directly entering the gas turbine and diesel engine with the air without filtering treatment will not only directly affect the combustion efficiency of the fuel, reduce the power output performance of the ship, but also cause continuous corrosion to the metal structure and shorten the normal service life. Therefore, ships are generally equipped with air intake filters device to filter and separate intake solid particles and salt mist; however, when the installation position of the intake filter device is low, the intake filter device will be eroded and impacted by a large amount of rain waves and water mist; this undoubtedly increases the The water removal burden of the air filter device; especially in severe cold weather, it is easy to cause ice inside the air intake filter device, affecting the normal operation of the air intake filter device; the air intake filter device must consider the function of blocking rain waves and water mist, and prevent internal Icing; while the existing air intake filter device has low efficiency in blocking rain waves and water mist, and the anti-icing effect is not good
