Abstract
The utility model relates to a bounding wall, in particular to an environment-friendly array dustproof canopy which is characterized in that multi-dimensional curved deflectors which are adjustable in gradient are installed on bracket units; the bracket units are assembled into an array dustproof canopy according to using requirements and stacked material is shielded inside the canopy. In the case of strong wind, main air flows from above the stacked material along the deflectors and part of the air slows down under the action of the damping holes of the deflectors and a curved flow passage, thus reducing the kinetic action of high-speed air flow and reducing dust and granule in the air flow. Sprayers facing the stacked material can also be installed on the bracket units around the stacked material; the arrangement of the deflectors or the sprayers or both can block the majority of the dust in the air which causes dust pollution. The dustproof canopy is composed of separate units and is simple in structure, wide in application, convenient to assemble and dismantle and can be used repeatedly. Therefore the dustproof canopy can be used to keep powder material off dust in open air.
Description
Technical field
The utility model belongs to a kind of enclosure wall, is specifically related to dustproof enclosure wall.
Background technology
The dust pollution of control powder and granule shape material (for example: ore in sand form, coal, building sandstone, salt etc.) large-scale storage in open system field is the green technology problem of public attention.The technology that extensively adopts mainly contains at present: spray watering, case hardening, the covering of net curtain, windbreak etc., and the single or comprehensive use of these methods can be alleviated the airborne dust degree to a certain extent, but this method exists certain suitable limitation again.Though build and hugely cover the warehouse or silo can thoroughly solve dust pollution, its cost is high, is difficult to promote.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, applicability is wide, economical and practical, the dustproof respond well dustproof curtain of an environmental protection array account.
For achieving the above object, the utility model adopts following technical proposals:
The dustproof curtain of a kind of environmental protection array account, comprise the array-support structure that the carrier unit by some differing heights is arranged to, be installed in the deflector at carrier unit top, the windward side of deflector and the angle between the ground are 90 °～150 °, the curved type of the shape of cross section of said deflector, on deflector, form vertically continuous air conducting road, on deflector, also have damping hole, its percent opening is 15～67%, and the percent opening of the deflector of upwards being arranged by ground is by 0.2～1.2 geometric progression segment increasing.
Dustproof curtain account height is 2.5～30m, and carrier unit is to be formed by connecting by column and main girder, and deflector is a rectangle, and its length is 1～10m, and its width is 0.6～2.0m, and thickness is 0.5～3mm.
On the carrier unit around the bank, be provided with spray equipment towards bank.
The utility model is applicable to open pile stock ground dustproof of the powder and granule shape material of mine, power plant, harbour, enterprise or building site, can be arranged on around the storage house, set-up mode can adopt straight line, camber line array or enclosed type, and angle between deflector windward side and the ground and curtain account height are determined according to condition such as material property, site area, material stack height, ambient conditions, prevailing wind direction and maximum wind velocity.When the wind comes from, air-flow is directed to two parts when contacting with the windward side deflector, wherein primary air flows through above bank along deflector, and the wind speed that makes the script high velocity stream cross the material surface obviously reduces, and has reduced air-flow and material turbulent surface flow, the caused airborne dust of eddy current; The remainder air-flow slows down under the compound action of deflector damping hole and curve runner, has reduced the kinetic energy of high velocity air, has slowed down the airborne dust effect to material.Simultaneously, shunted by drainage face in the turbulent flow of the region of no pressure at the original air-flow of the leeward side of deflector and the stockpile back side, part airborne dust and deflector leeward side bump against or settle down after by damping hole and curve runner kinetic energy loss.Also can open the spray sprinkler system where necessary, to strengthen dustproof effect.In sum, under the double action of dredging and blocking of hydrodynamic characteristic to air-flow of windward side and leeward side, reduced the kinetic energy of air stream effectively, be aided with the spray sprinkle water function in case of necessity, thereby reduced the Dust Capacity that air-flow is carried secretly, suppressed the atmosphere pollution of zone of protection effectively.The utlity model has following advantage: support, deflector etc. is designed to assembly of elements, these assembly of elements can be combined into array curtain account easily by different instructions for uses and use, compare with device with other fixed blind dust-tight constructions, have simple in structure, good dustproof effect, characteristics such as cost is low, and is reusable.

The specific embodiment
As depicted in figs. 1 and 2, the dustproof curtain of a kind of environmental protection array account, comprise the array braced structures that the carrier unit 1 by some differing heights is arranged to, be installed in the deflector 3 at carrier unit 1 top, the windward side of deflector 3 and the angle between the ground are 90 °～150 °, the curved type of the shape of cross section of said deflector 3, on deflector 3, form vertically continuous air conducting road 10, on deflector 3, also have damping hole 11, its percent opening is 15～67%, and the percent opening of the deflector 3 of upwards being arranged by ground is by 0.2～1.2 geometric progression segment increasing.Wherein, dustproof curtain account height is 2.5～30m.Carrier unit 1 is to be formed by connecting by tubular type column and main couple.Deflector 3 is a rectangle, and its length is 1～10m, and its width is 0.6～2.0m, and thickness is 0.5～3mm.Can also on the carrier unit 1 around the bank, be provided with spray equipment towards bank.
In the present embodiment, the air deflector on environmental protection array dustproof curtain account bottom and top is separately installed with down drainage wing plate 6 and last drainage wing plate 5, and carrier unit 1 adopts anchoring piece 7 fixing, also can adopt concrete foundation to fix.On carrier unit 1, be provided with deflector bearing 2, so that adjust the gradient of deflector.Between carrier unit 1, also be provided with support connecting rod 8.
The open-air coal yard in certain harbour, rectangle, 120m long from south to north, the wide 90m of thing, the high 8m of dump, 180,000 tons of total coal storages.The winter-spring season cardinal wind is the northwest, 7 grades of maximum wind powers, and extreme maximum wind power can reach 9～10 grades.The coal yard coal dust fills the air when blowing, and air pollution is serious.Adopt the utility model, form the dustproof curtain of the closed array formula account that southeast side is opened with carrier unit, and connect the spray equipment sprinkler system.Support height 10m, 130 ° of windward side and ground angles, deflector section length 3m, adding radius of curvature is the upper and lower drainage plate of 1m, simple and easy anchoring.After adopting the utility model, do not adopt the spray watering, two season of autumn in summer efficiency of dust collection reach more than 80%.Wherein efficiency of dust collection is that the dustiness ratio calculation under coal yard leeward same position, the same wind friction velocity in the air sampling draws with before and after use the utility model.After opening spray equipment, efficiency of dust collection can reach 85～88% spring, can reach for 85～93% (having freezing effect winter) winter, and the control air pollution is respond well.
