Humidification type dustlaying agent, preparation method, and application

Abstract

This invention discloses a method for preparing wet dust-inhibiting agent and its application. The wet dust-inhibiting agent is composed of: polyoxyethylene nonyl phenyl ether OP-4 2-15%, OP-15 4-24%, ethylene glycol 0.5-10%, glycerol 1-10%, sodium dodecylbenzene sulfonate 0.1-5%, and tap water. The method comprises: adding tap water into a reaction kettle, heating to 40 deg.C, adding the raw materials, stirring to completely dissolve, keeping for 30 min, taking out, and packaging. When used, the wet dust-inhibiting agent is diluted with tap water at a ratio of 1 :( 1000-2000), and sprayed by spraying car or specific spraying apparatus onto dust-producing zone such as coal piles and raw material fields.

Description

technical field [0001] The invention relates to the technical field of environmental protection, and is a wetting dust suppressant and its preparation method and application. Dusty work area. Background technique [0002] Dust pollution is one of the world's environmental hazards. For half a century, people have been working on the prevention and control technology of dust pollution. The particle size of general dust is mostly less than 30um, which is a kind of inhalable particulate matter. The harm of particulate matter to human health is closely related to the particle size and chemical composition of the particulate matter, as well as the deposition site in the respiratory tract. Inhalable particles can enter the respiratory tract of the human body along with the human breath, causing great harm to human health. Air particles can not only cause lung cancer, but also have a great relationship with the incidence of heart disease. At present, there are many methods of d...

Problems solved by technology

[0003] Covering the dust pile with a thatch net is a traditional dust suppression method, but because sometimes short-term dust suppression (such as 3 to 5 days) is required, it is inconvenient to use this method, and the cost of using the thatch net is high

Another measure to control dust is wet control, that is, watering method. The advantage of this method is that it is easy to operate, but the disadvantage is that the water only wets the surface of the dust and cannot penetrate into the interior of the dust, which leads to rapid evaporation of water and watering High frequency

Cause a lot of waste of water resources and increase labor and equipment costs

At present, there is another kind of chemical dust suppressant used in dust control. It belongs to the consolidation type. After diluted with water and sprayed, it can form a hard shell on the surface of the dust, thereby controlling the escape of dust. This dust suppressant is suitable for Long-term dust suppression, the cost of dust suppression per unit is high, and this kind of hard shell cannot withstand rolling, so it cannot be used for dust suppression on roads, etc.
