Abstract

The invention provides a wet type dust suppressant for dust control. The wet type dust suppressant consists of the following substances in percentage by mass: a mixed surfactant, a wetting agent, a preservative and water, wherein the mixed surfactant is a mixture of an anionic surfactant alkane sulfonate and nonionic surfactants alkylphenol ethoxylates and fatty alcohol-polyoxyethylene ether; and the wetting agent is a mixture of polyhydric alcohols and monohydric alcohols. According to the dust suppressant disclosed by the invention, the dust surface tension can be reduced, and the wettability, permeability and adsorptivity are improved, so that the aims of rapidly catching dynamic small-particle dust and suppressing the dust from flying are achieved.

Description

technical field [0001] The invention relates to a wetting dust suppressant for controlling dust, which belongs to the technical field of environmental pollution control. Background technique [0002] Coal is an important resource to support the development of the national economy. However, in the contemporary era of comprehensive development of coal resources, coal dust pollution and waste of resources have become problems that we need to solve urgently, and have also affected the development of coal resources. [0003] With the continuous increase of the country's environmental protection and the gradual improvement of the people's awareness of self-rights protection, coal dust pollution has become an impact on people's lives, especially dust and fog below 50 microns and above 1 micron, polluting the ecological environment and wasting natural resources. one of the important reasons. [0004] By the end of 2011, a total of 702,942 cases of pneumoconiosis had been reported n...
