A two-degree-of-freedom bionic windproof and dust-suppressing wall based on the microstructure of Digrass leaves

Abstract

The invention discloses a double-degree-of-freedom bionic wind-proof and dust-suppressing wall based on the microstructure of the grass leaf surface. Utilizing the ecological structure principle of the grass grass, it is woven with high-molecular polyethylene fibers to make oblique convex ribs with the leaf surface of the grass grass- The double micro-nano structure bionic dust suppression net of the scales absorbs and intercepts a large amount of particulate matter, and achieves the effect of windproof and dust suppression through the joint action with the steady flow windshield. The invention has the advantages of simple structure, strong applicability, obvious windproof and dust suppression effect, adjustable opening ratio of the steady flow windproof cover, displacement in the direction of air flow, strong resistance to strong wind impact, self-cleaning bionic dust suppression net, and repeatability The function of absorbing pollutants such as particulate matter and dust can avoid secondary pollution. According to the actual situation, the windproof and dust suppression wall units can be connected to form a certain area of ​​windproof and dust suppression belt.

Description

technical field [0001] The invention relates to a windproof and dust-suppressing wall, and in particular provides a dual-degree-of-freedom bionic wind-proof and dust-suppressing wall based on the microstructure of the grass leaf surface, which belongs to the technical field of atmospheric environmental protection implementation. Background technique [0002] At present, the air pollution problem has caused great harm to residents' life and work, such as coal burning, vehicle exhaust emissions, and ventilation of farms, etc. will cause relatively large pollution to the nearby air. In particular, steel mills, large-scale farms and construction sites will produce a large amount of fine particle dust into the atmosphere, which will reduce local visibility when combined with water vapor in the atmosphere, resulting in a series of environmental problems such as smog and may cause nearby pollution. health problems of residents. Therefore, in areas with severe air pollution such as...

AI Technical Summary

Problems solved by technology

[0003] To sum up the disadvantages of the existing wind-proof and dust-suppressing walls are mainly: most devices reduce the amount of dust generated by reducing the wind speed, thereby achieving the purpose of reducing particulate matter, while for the particles that have been raised, they usually rely on the principle of collision mechanism to intercept the particles, that is, by reducing Wind speed is used to reduce the movement speed and momentum of particles so that they cannot pass through the windproof and dust suppression wall, but this part of the particles is still suspended in the air and cannot be effectively removed; even if a small number of dust-proof nets try to use adsorption to remove particles, due to The particles attached to the surface are saturated after a certain period of time, resulting in a very limited ability to absorb particles, and when strong wind blows, it is easy to cause secondary pollution of particles; in addition, the opening ratio of most windbreak walls is fixed and cannot be automatically adjusted with the wind speed. and the windshield part has no degrees of freedom
