The high-efficiency coal desulfurizer has the advantages of high desulfurization precision, high desulfurizing property, high sulfur capacity and high crushing limit, and is convenient to use.
Description
technical field:
The present invention relates to a kind of efficient fuel coal sweetening agent, specifically a kind of chemical materials.
background technology:
Fine particle is also known as particulate, fine particle, PM2.5.Fine particle refers in ambient air
aerodynamicsequivalent diameter is less than or equal to 2.5
micronparticulate matter.It can be suspended in air the long period, and content concn is higher in atmosphere for it, just represents atmospheric pollution more serious.Although PM2.5 is the component that in earth atmosphere composition, content is little, it has important impact to Air quality and visibility meter etc.Compared with thicker Atmospheric particulates, PM2.5 particle diameter is little, and area is large, active strong, easily subsidiary poisonous,
objectionable impurities(such as,
heavy metal, microorganism etc.), and residence time is in an atmosphere long, fed distance is far away, thus larger on the impact of HUMAN HEALTH and atmosphere quality.
PM2.5 can be by
sulphurwith
nitrogenoxygenate conversion form.And these gas pollutants often the mankind to fossil oil (coal, oil etc.) and rubbish
burningcause.In developing country, coal burning is the major way of family's heating and power supply, and it is very necessary and critical that the sulphur produced fire coal thus carries out desulfurization.
summary of the invention:
The object of the invention is to provide a kind of desulfurization precision high, easy to use, desulfurization performance is high, and Sulfur capacity is high, a kind of efficient fuel coal sweetening agent that crushing strength is high.
