Abstract
The utility model relates to a weatherability environmental porous plate wall, which is suitable for the windproof and dust deduction at open coal fields and granular bulk cargo yards and can be taken as a supporting engineering equipment to prevent sand, land desertification and for plant survival as well. The utility model belongs to the environmental protection and management area. The structure comprises a steel support and porous plates, and the steel support comprises porous plate mount support components and inclined brace components. A number of porous plates are installed at the porous plate mount support components, and the inclined brace components are arranges at one side of the porous plate mount support components. The porous plate is weather proof and the section of the porous plate is a V shaped or arc-shaped cross-section. The holes are opened at the porous plate, and the hole opening rate is calculated as 10% to 28% of the virtual unwrapped area of the porous plate. The height of the weatherability environmental porous plate wall is arranged as 1.1 to 1.8 times of the height of the shielded coal pile or granular bulk pile. The ratio between the height H of the porous plate mount support components and the horizontal supporting distance B of the inclined brace components is 3 to 6:1.
Description
Technical field
The utility model Weathering Perforated Panel Environment Protecting Wall relates to be a kind of be applicable to the windproof depositing dust of open-air Coal Stack Yard, granular bulk storage yard and can be used as sand control, prevent desertification of land, ancillary works device that vegetation survives.Belong to environmental protection and improvement field.
Background technology
The dusty gas (as cement plant, steam power station, quarrying stope, chemical plant, petrochemical plant etc.) that airborne micronic dust is mainly discharged by superfine little floating particle, factory, form by the fine grained that blows afloat under the wind effect etc.Studies show that: when wind speed reaches 2～3m/s (light breeze), 100 micron particles will be blown afloat, we usually see the phenomenon that road, harbour, Coal Stack Yard are covered all the sky under the strong wind, this phenomenon has caused that the pulmonary tuberculosis number of the infected sharply increases in the urban population, because pollution caused by coal dust causes the helicopter falling accident to happen occasionally.
Have greater environmental impacts, airborne dust is concentrated is some Coal Stack Yard and bulk storage yard.Enterprises such as transhipment coal wharf, steam power station, coking, gasification are equipped with open-air Coal Stack Yard.The main cause of Coal Stack Yard airborne dust is windrow, gets the airborne dust of material, haul operation generation that secondly produce airborne dust owing to static wind-induced stockpile surface forms eddy current, statistics shows that dump plays dust quantity and accounts for 2 ‰ of dump total amount.
Take the major measure of dustproof depositing dust to have following several to open-air Coal Stack Yard or bulk storage yard both at home and abroad at present:
1, spray.A kind of simple and easy and dust-laying effect is method preferably, but water resource is lacked or the northern area of freezed in winter just is not suitable for, and the moisture content of coal only reaches 8% effect that could reach depositing dust when above preferably, and its operating cost is big.
2, cover.Adopting straw mat, nylon knitmesh to cover, is a kind of makeshift, and the stockyard of piling, getting for need is unfavorable.
3, plantation shelter-forest.The soil input that these needs are huge, the water and soil condition that also needs confession trees and vegetation to survive simultaneously, current conditions is not many to be seen.
4, the stockyard is totally-enclosed.Anti-dust effect is preferably arranged, but invest hugely, and operating cost such as ventilation of inside, stockyard, daylighting, depositing dust is quite high.
5, build storage tank.This kind method can reach discharging in a organized way, and effect should be advanced, but its investment is bigger, also need build the stockyard simultaneously, and operating cost is high.
6, windproof net.Can be divided into flexible net and rigid mesh, its checking effect can reach 60%～80%, no operating cost, and investment is little.With regard to the present economic technology condition of China, should be more feasible technical measures of present stage.But the flexible net life-span is short, and the panel material of rigid mesh is short application life.
Summary of the invention
The utility model purpose is to provide a kind of Weathering Perforated Panel Environment Protecting Wall at above-mentioned weak point, be applicable to the windproof depositing dust of open-air Coal Stack Yard, granular bulk storage yard and can be used as sand control, prevent desertification of land, ancillary works device that vegetation survives.
Weathering Perforated Panel Environment Protecting Wall is to take following scheme to realize: the Weathering Perforated Panel Environment Protecting Wall structure is made up of steel work supporter, porous plate, the steel work supporter has porous plate mounting bracket assembly and bearing diagonal assembly, some porous plates are installed on the porous plate mounting bracket assembly, and the bearing diagonal assembly is arranged on porous plate mounting bracket assembly one side.
Porous plate is the weatherability porous plate, and the porous plate cross section is " V " shaped sections or circular section, has the hole on the porous plate, and percent opening is calculated as 10%～28% with the effective developed area of porous plate.
Weathering Perforated Panel Environment Protecting Wall can reduce the wind speed of incoming flow wind effectively, change a part of incoming flow wind by the wind direction behind the wall, can make incoming flow wind behind wall, produce the eddy current wake flow of multiply cross beat, interfere with each other, fragmentation, make the incoming flow kinetic energy produce bigger loss, and then the wind speed behind the wall is reduced, to reach the effect of checking dust suppression.The porous plate that installs on the Weathering Perforated Panel Environment Protecting Wall adopts the organic-inorganic composite material of weatherability, can do the adjustment on the material according to weather (as the sea wind weather, little acid gas is waited, many dirt weather, plateau climate) requirement, and can reach 15 years its service life.This environmental protection wall is effectively being protected in the distance, and the checking rate can reach 80%, and it is simple in structure, and engineering construction is easy, reduced investment, and no operating cost, use in applicable open-air Coal Stack Yard or granular stockyard in bulk newly-built or that built.
The characteristics of Weathering Perforated Panel Environment Protecting Wall:
1. the utlity model has significant windproof dust-laying effect;
2. the match weatherability porous plate that uses of Weathering Perforated Panel Environment Protecting Wall adopts the organic-inorganic composite material of weatherability, and according to different climatic characteristics such as sea wind weather, little acid gas is waited, and many dirt weather, plateau climate etc. can be done suitably to adjust to be suitable for to material.The shape of plate and percent opening are to determine according to aerodynamic principle and wind tunnel experiment, are the products that theory and practice combines;
3. the utility model is simple in structure, and engineering construction is easy, reduced investment, no operating cost, can adapt to newly-built, build the use in stockyard.
