Abstract

The invention discloses a compound type foam dedusting agent. The compound foam dedusting agent comprises, by weight, 0.2%-0.3% of alpha olefins, 0.3%-0.5% of alpha-olefin sulfonate, 0.01%-0.03% of lauryl sodium sulfate, 0.03%-0.05% of sodium dodecyl benzene sulfonate, 0.3%-0.4% of trimethyl-1-propanaminium iodide, 0.02%-0.04% of cocoamido propyl hydroxy sulfoBetaine, 0.01%-0.02% of dodecyl dihydroxyethyl amine oxide, 0.01%-0.03% of modified polyethoxylated silicone, 0.02%-0.03% of polyoxyethylene fatty acid, 0.1%-0.2% of pentaerythritol oleate and balance water. Due to the fact that the pentaerythritol oleate was regarded as the corrosion inhibitor and added into the foam dedusting agent, the corrosivity on electromechanical equipment is greatly lowered, and the working environment of the workplace with the high concentration of dust is effectively improved.

Description

technical field [0001] The invention relates to a dust remover used in coal mines, in particular to a composite foam dust remover. Background technique [0002] In recent years, with the improvement of mechanization, many industries have entered a period of high output and high rhythm. With the increase of output and the acceleration of production rhythm, many domestic industries (such as: gold mines, coal mines, quarries, Metal products processing industry, wood processing industry, etc.) are all faced with the problem that high concentration dust affects workers' physical and mental health and safety production. According to the actual measurement, the dust concentration of fully mechanized mining face can reach 2500mg / m 3 -3000mg / m 3 , while the dust situation of fully mechanized caving work is more serious than that of general fully mechanized mining face. When the coal shearer is cutting coal, moving frame and coal setting in parallel, the instantaneous original total...
