Description
Technical Field
The invention belongs to the technical field of ship unloader equipment, and relates to a dust removal device for a hopper of a grab ship unloader.
Background
With the economic development, the port construction is suddenly advanced, and the demand of ship unloaders is more and more. The bulk cargo ship unloader has a hopper with a large amount of dust flying in the loading and unloading process, which seriously pollutes the atmosphere. In order to protect the environment, a dust removal device is required to be adopted at the hopper of the bulk cargo ship unloader;
the dust removal technology applied in the prior bulk cargo handling system mainly comprises dry dust removal and wet dust removal. Dry dedusting is generally used for special chemical materials, such as sulfur, fertilizers, and the like; wet dust removal techniques are widely used and are commonly used for conventional materials such as coal, ore and the like. The wet dust removal system mainly comprises dry mist dust removal and water mist dust removal, wherein the two wet dust removal modes aim at different dust particle sizes, the dry mist dust removal system mainly inhibits particles of 5-50 mu m grade, and the water mist dust removal system mainly inhibits particles of 50-500 mu m grade. The wet dust removal system is applied to the bridge type grab ship unloader, a water mist dust removal system is usually adopted, and the dry mist dust removal system is also applied to the ship unloader along with the improvement of environmental index requirements. However, the application for a period of time shows that the range of the granularity of the dust generated in the operation of the ship unloader is wide, and the effect of inhibiting the dust with the granularity of 50-500 mu m by only adopting a dry fog dust removal system is not obvious; in the prior art, a single dry fog or water fog dust removal system is not comprehensive enough in dust suppression, and cannot simultaneously suppress dust particles within the range of 5-500 mu m.

The air suction opening of the dust remover is an open space formed by the edge of the hopper opening and the wind shield, and the air outlet is an air curtain pipeline. The blanking grid consists of a steel framework and a rotating baffle. The invention can greatly reduce the air quantity of the dust remover, thereby reducing the energy consumption. The dust removal device also has the advantages of good dust removal effect, no limitation of materials, high safety factor and convenient maintenance. The device is widely applied to equipment such as grab ship unloaders and ordinary hoppers, but has the defects.
