Embodiment 1

[0013] Weigh the following components by weight percentage: 27% nonylphenol polyoxyethylene ether, 13% sodium laurate, 35% ethylene glycol, and 25% water; mix the components well to obtain a wet dust catcher .

[0014] When using the wetting dust-catching agent prepared in this example to remove dust, first dilute it with water, and the mass fraction of the wetting dust-catching agent is 0.02-0.05%.

Embodiment 2

[0016] Weigh the following components by weight percentage respectively: 30% nonylphenol polyoxyethylene ether, 10% sodium laurate, 30% ethylene glycol, and 30% water; mix the components well to obtain the wet dust catcher .

[0017] When using the wetting dust-catching agent prepared in this example to remove dust, first dilute it with water, and the mass fraction of the wetting dust-catching agent is 0.02-0.05%.

Embodiment 3

[0019] Weigh the following components by weight percentage respectively: 28% nonylphenol polyoxyethylene ether, 9% sodium laurate, 38% ethylene glycol, and 25% water; mix the components well to get the wet dust catcher .

[0020] When using the wetting dust-catching agent prepared in this example to remove dust, first dilute it with water, and the mass fraction of the wetting dust-catching agent is 0.02-0.05%.

Abstract

The present invention relates to the technical field of chemistry, particularly to a wetting dust catching agent, which comprises the following components, by weight, 10-30% of polyoxy ethrlene nonyl phinyl ether, 5-25% of sodium laurate, 20-40% of ethylene glycol, and 20-30% of water. According to the present invention, the polyoxy ethrlene nonyl phinyl ether, the sodium laurate, the ethylene glycol and the water are combined according to a certain ratio to be used so as to provide a good dust removing effect, effectively inhibit secondary dust flying, and provide a wide application range; dust removal efficiency can be 80-90%; compared with the required water in the prior art, the required water for obtaining the same dust removal efficiency in the present invention is reduced by more than 50-80%; the used raw materials are cheap, cost is low, and the mass fraction of the wetting dust catching agent is only 0.02-0.05% during use so as to provide a characteristic of less use amount; and the wetting dust catching agent has characteristics of good water solubility, environmental protection, no toxicity, no harm, no secondary pollution on the environment, and no equipment corrosion after long term use.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to a wetting and dust-catching agent. Background technique [0002] In iron and steel metallurgy, mining, coal logistics parks, bulk cargo terminals and ports, vehicle and ship transportation, electric chemical industry, building materials and other industries, it is easy to generate a large amount of dust in places such as material excavation, crushing, feeding, transportation, unloading, and loading. The existing technologies used to deal with dust generally have the problems of large investment, high cost, low dust removal efficiency, and short dust removal retention time. The existing dedusting technology mainly adopts two kinds of dry dedusting method and wet dedusting method. Among them, the dry dust removal method includes forced ventilation, bag dust collection or electric dust removal; the wet dust removal method uses water mist to reduce dust. Dry dust removal uses ind...
