Abstract

The invention discloses an environmental-friendly coal ash catching settling agent and a preparation method thereof and belongs to the field of coal flying dust treatment. The environmental-friendly coal ash catching settling agent comprises 3-5wt% of a catching agent, 6-10wt% of an accelerant, 2-5wt% of an adhesive, 3-5wt% of a film forming agent and the balance of water. The formula disclosed by the invention has a long-acting environmental-friendly effect on settled coal dust and inhibits the coal dust from flying again, so that secondary flying dust is reduced. By combining a surface active substance with a multifunctional macromolecular polymer component, the net structures of the polymeric molecules have stronger coal dust affinity and can tightly lock the coal dust, so that an effect of inhibiting secondary flying dust is achieved.

Description

technical field [0001] The invention relates to a pulverized coal capture and sedimentation agent and a preparation method thereof, in particular to an environment-friendly coal dust capture and sedimentation agent and a preparation method thereof, belonging to the field of coal dust control. Background technique [0002] The smog issue has become the environmental issue with the highest public concern. The main source of air pollution in my country is coal dust pollution, with a contribution rate of 90%. Therefore, the focus of air dust pollution control is coal dust control. Coal dust will not only damage the health of relevant employees and bring about occupational pneumoconiosis hazards, but also lead to serious safety production accidents. For example, excessive concentration of suspended coal dust will cause coal mine explosions. In addition, the high concentration of coal dust in the working environment will also accelerate the wear of mechanical equipment, shorten t...
