Gas-solid separation type sand barrier

Abstract

The invention provides a gas-solid separation type sand barrier. The gas-solid separation type sand barrier is composed of two rows of combined sand barrier bodies arranged side by side. The gap is formed between the two rows of combined sand barrier bodies. Each row of combined sand barrier body is composed of multiple V-shaped single sand barrier bodies arranged side by side. The gap is formed between every two adjacent single sand barrier bodies in the same row of combined sand barrier bodies. The gap between every two adjacent single sand barrier bodies in one row of combined sand barrier bodies and the gap between every two adjacent single sand barrier bodies in the other row of combined sand barrier bodies are alternately spaced. The opening direction of the single sand barrier bodies in one row of combined sand barrier bodies is opposite to the opening direction of the single sand barrier bodies in the other row of combined sand barrier bodies. The separation sand barrier serves as a novel sand barrier, and sand grains and airflow in wind-sand flow are easily separated; the sand prevention efficiency is high, and the installation speed is high; and construction is easy and convenient, price is low, and the cost performance is high.

Description

technical field [0001] The invention belongs to the technical field of engineering sand control, and relates to a speed-reducing sand-blocking facility with a high vertical ventilation type sand barrier structure, in particular to a ventilation type air-solid separation type sand barrier. Background technique [0002] Wind erosion and wind accumulation are the basic manifestations of wind and sand activities in arid areas. They not only form the surface morphology of desert areas, but also pose serious threats to people's production and life. For example, the sand carried by the wind reduces the visibility of the atmosphere, affects transportation, damages plants and wires, wears out buildings and machines, blows away organic matter on the soil surface, and reduces soil nutrients. Due to global warming and intensified human activities, more and more land has become bare land, which intensifies the process of desertification in arid and semi-arid regions. Land desertificatio...

Problems solved by technology

However, there is still an area of ​​enhanced airflow at the top of the sand barrier, and the effect of gas-solid phase separation is still unsatisfactory, and some sand particles will still be deposited in the protected area
