摘  要:空气中可吸入颗粒物不仅影响着我国的环境,更是危害着人民的安全。目前对于道路扬尘的清洁仅仅依靠洒水,但浪费了水的同时只起到了暂时的清洁作用。通过DPM模型分析道路上扬尘的运动情况,设计一种可以自动吸附、过滤、清洁的装置以实现清洁与节能。实验表明,将工业新型纤维覆膜吸附除尘方式应用于道路除尘,能够充分发挥材料性能优势;利用道路噪声和雨水资源完成装置的清洁,无需动力源即可实现扬尘清理和自身清洁,减轻了人力工作负担;模块化结构设计,为后期材料更换提供便捷。这一产品的使用对道路扬尘污染治理具有一定意义。

Abstract: Respirable particles in the air not only affect the environment of our country, but also endanger the safety of people. At present, the cleaning of road dust only depends on sprinkling water, but it simply plays a temporary role in cleaning while wasting water. The movement of dust on the road is analyzed by DPM model, and a device which can automatically absorb, filter and clean dust is designed to realize cleaning and energy saving. The experimental results show that the application of the new industrial fiber film adsorption dedusting method to road dedusting can give full play to the advantages of material performance, and the cleaning of the device can be completed by making use of road noise and rain water resources. Dust cleaning and self-cleaning can be realized without power source, which reduces the burden of human work; modular structure design provides convenience for material replacement in the later stage. The use of this product is of certain significance to the treatment of road dust pollution.

Keywords: dust cleaning; energy saving and emission reduction; new fiber film

引言

为打好大气污染防治工作,扬尘综合治理已成为首要任务。道路扬尘来源主要包括汽车尾气颗粒物类排放性源、磨损和再悬浮类非排放性源[1]。非排放性源之中,影响扬尘污染的主要因子是道路積尘量,处理道路积尘成为治理扬尘的关键[2]。

当前治理道路扬尘采取的主要手段是洒水清扫,辅以日常保洁。而实践表明,依靠洒水来抑制扬尘,容易引起路面早期破坏、增加道路养护成本、降低了路使用寿命,更易形成大的交通安全隐患[3]。

综上,道路扬尘会影响空气质量、损害附近群众及司乘人员的身体健康。同时,现阶段的治理方法并不能做到有效处理扬尘。基于此,在考虑道路气流场模拟颗粒物输送轨迹的情况下,将除尘单元与声屏障有机结合,吸附过滤、收集处理,同时设置自清洁模块,实现持久有效的除尘。……
