Foam generating agent for wet dust collection

Abstract

The invention discloses a foam producing agent for wet-type dust collection. According to the weight percentage, the foam producing agent for the wet-type dust collection comprises: 0.2%-6% of lauramide propyl glycine betaine, 0.15%-0.3% of hexadecyl tri-methyl ammonium bromide, 0.4%-1.3% of fatty alcohol-polyoxyethylene ether sodium sulfate, 1%-2% of sodium dodecyl benzene sulfonate, 0.2%-0.8% of dodecyl benzene glycine betaine, 0.2%-0.9% of fatty acid glycerolipid, 0.4%-2% of potassium polyacrylate, 1.5%-2.4% of perfluor octyl sulfo tetraethyl ammonium salt, 0.5%-1.5% of sucrose fatty acid ester, 0.3%-1.2% of diocytyl sulfo sodium succinate, and the balance is water. The foam producing agent for the wet-type dust collection is capable of cohering the dusts on the ground for a long time, avoiding the dusts from flying along with the wind because of the drying ground, and performing the collecting function to a duster for a long time. The foams produced by the foam producing agent for the wet-type dust collection have good biological degradability, and both the environmental protection coefficient and the safety coefficient are high.

Description

technical field [0001] The invention relates to a dust-removing foam agent for underground coal mines, in particular to a foam generating agent for wet dust collection. 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 occ...

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
