A foam generating agent for wet dust removal

Abstract

The invention discloses a foam generating agent for wet dust removal. The foam generating agent comprises the following components in percentage by weight: 0.1%-0.4% of coconut oil diethanolamide, 0.2%-0.6% of perfluorooctyl sulfo tetraethylammonium salt, 0.1%-0.4% of sodium iso-octanol sulfate, 0.01%-0.06% of sodium 2-ethylhexyl succinate sulfonate, 0.03%-0.05% of sucrose fatty acid ester, 0.01%-0.03% of sodium dioctyl sulfosuccinate, 0.05%-0.08% of hexadecyl trimethyl ammonium bromide, 0.03%-0.07% of coconut oil amide propyl betaine, 0.01%-0.05% of lauryl dimethyl benzyl ammonium chloride and the balance of water. Foam generated by the foam generating agent is of a double-molecular-layer structure, the hydrophilic groups of two layers of molecules face towards a foam liquid film, the outside molecular layer hydrophobic groups face towards air outside the foam, the inside molecular layer hydrophobic groups face towards air inside the foam, hydrophobic groups of the foam molecules, are rapidly combined with dust so that the dust is wetted and is adhered to the surface of the foam and with the fracturing and settlement of the foam, the dust-falling effect is achieved.

Description

technical field [0001] The invention relates to a foam generating agent for coal mines, in particular to a foam generating agent for wet dust removal. Background technique [0002] Nowadays, with the progress and development of society, the degree of mechanization has been greatly improved and the pace of production has been accelerated, which has become the trend of many industries, but many problems affecting production safety and physical and mental health of workers have also followed. For industries such as coal mines and gold mines, with the improvement of the degree of mechanization, the concentration of dust at the workers' work sites is also getting higher and higher, which leads to the worsening environment of the work sites. The high concentration of dust seriously threatens the safety of the workplace and the physical and mental health of workers. First of all, the danger of dust explosion is ubiquitous and serious; second, dust has serious occupational hazards....

AI Technical Summary

Problems solved by technology

Existing foam generators are mainly formulated with surfactants such as alkylbenzenesulfonate, alkylsulfonate or sulfate, and some additives in a certain proportion. Although they have played a certain role, there are still many problems , Such as: weak acid and alkali resistance and hard water resistance, too long foam stability time, too large average diameter of bubbles in foam, etc. These problems also greatly weaken the dust removal effect and practicability of foam dust removal technology
