Description

Wind-proof dust-settling net with flow guide plate and composite retaining wall for bulk cargo storage yard

Technical Field

The utility model relates to a building structure in coast engineering and the port engineering field, concretely relates to dust fall net is prevent wind with compound barricade of guide plate to bulk cargo store yard.

Background

With the development of economy in China, a port bears the loading, unloading, transporting and storing of a large amount of bulk cargo materials, and dust pollution of a storage yard of the port gradually becomes a non-negligible problem while bringing great economic benefits. Particularly, the stockpiles of some coal wharfs, ore wharfs and the like can form dust with wind and can cause serious pollution to the environment around port yards along with atmospheric diffusion.

In contrast, environmental protection facilities and dust prevention and control level development of each port in China are unbalanced, the prevention and control efficiency of coastal ports in south and north are greatly different, particularly, the northern ports are seriously lack of water and are low in temperature in winter, the freezing period is as long as several months, the wet dust removal efficiency is low, and the dust pollution situation is still severe. At present, the windproof net is a windproof dust suppression measure generally adopted for solving the problem of dust pollution on port and wharf storage yards at home and abroad recently, has a certain protection effect on dust pollution of the storage yards, but the effective dust suppression rate of the conventional vertical windproof net is still not ideal.

After the incoming wind passes through the vertical windproof net, seepage wind passing through the windproof net and the streaming wind bypassing the windproof net can be formed. Although the wind speed of the streaming wind is high, most of the wind exists in the upper area of the flow field behind the net, so that the material stacking behind the net cannot be greatly influenced. Although the wind speed is not large, seepage wind can directly act on the surface of the material stack behind the net, particularly the windward slope and the top surface, and is extremely unfavorable for the dust particles on the surface of the stack.

Disclosure of Invention

An object of the utility model is to overcome the defect among the prior art, provide a dust fall net is prevent wind with compound barricade of guide plate to bulk cargo store yard.

The technical scheme of the utility model as follows:

the utility model provides a dust fall net is prevent wind with compound barricade of guide plate in bulk cargo storage yard, includes: the front columns of the windproof net and the rear columns of the windproof net are connected with each other through inner cross rods and inner inclined rods; the top of the front column of the windproof net is provided with a guide plate upright column which is inclined backwards, and the top of the rear column of the windproof net is provided with a guide plate inclined strut which is connected with the guide plate upright column; a wind shield is arranged between the two adjacent wind-proof net front columns, and a guide plate is arranged between the two adjacent guide plate stand columns.
