  • the invention particularly relates to a dust suppressant for coal.
  • Common dust is mainly composed of organic particles such as coal ore fine particles and dust particles.

Therefore, in view of the above situation, grasping the fine particles of dust suppression is the key to floating of external air humidity, flashing, material flow, drop and other factors, and it is effective to manufacture large-area and deep-degree connection mechanisms of fine particles by high-tech means. It will be firmly solidified into one, so that it will not be evacuated, and the structure of the pile will not eliminate and reduce the dust of coal transportation.
  • Spraying water to suppress dust is to increase the water content of coal, especially the water content of surface particles. It is best to make the water content reach 6%-8% to increase the weight of the particles.

Description

一种煤炭的抑尘剂 技术领域
本发明具体涉及一种煤炭的抑尘剂。
背景技术
常见的灰尘主要由煤炭矿粉微粒、粉尘微粒等有机粒子共同构成。在汽车运输过程中在重力、风力的带动下向周围四处扩散形成粉尘污染。因而针对上述情况，抓住抑尘细微粒子是外界空气湿度、闪过、料流量、落差等因素变化而漂浮的关键，以现在高科技手段制造细微粒子的大面积、深程度连接机制，从而有效的将其牢牢的固化为一体，使其不在撤离出来，料堆结构组织之外，既可杜绝和减少煤炭运输扬尘。
喷水抑尘一是增加煤炭的含水量，特别是表层颗粒的含水量，最好使含水量达到6％-8％，以增加颗粒的重量；二是改变尘源表面粒径分布，主要是微全粒子的分布，由水式雾对微全粒子捕捉或附聚，粉尘吸湿会导致凝聚，影响颗粒的分散程度。粉尘中的吸附水以水膜形式包覆在粉尘颗粒表面，实际上它是粉尘颗粒的一个组成部分。水膜以极大的吸力包覆在粉尘胶体的表面，这种力最大可达到10000个大气压。但由于环境湿度予以改变这种水的含量，干燥挥发后又迅速恢复原型，成为全源。因此喷水抑尘防煤炭运输中产生的粉尘工作量大，效果不理想。
