The invention discloses a drying device for power plant coal. The drying device comprises a device base, connecting holes, fastening bolts and a humidity detection device; a fixing frame is arranged above the device base, stirring blades are installed on the surface of a second rotating shaft, and a heating element is arranged on the surface of the interior of a rotating drum; a discharging opening is formed in the middle of the bottom of the rotary drum, a collecting device is installed in the discharging opening, connecting plates are fixed to the two sides of the outer surface of the collecting device, the connecting holes are formed in the connecting plates, fastening bolts are installed in the connecting holes, and the humidity detecting device is installed in the collecting device; and the drying device for the power plant coal is provided with a first motor, a first rotating shaft, the rotating drum, a second motor, the second rotating shaft and the stirring blades, so that therotating drum can rotate, meanwhile, the second rotating shaft in the rotating drum drives the stirring blades to stir carbon powder in the rotating drum, and thus, the carbon powder is heated more uniformly.
Description
technical field [0001] The invention relates to the technical field of coal drying in power plants, in particular to a drying device for coal in power plants. Background technique [0002] Coal is a combustible black or brownish-black sedimentary rock that usually occurs in rocky formations or veins called coal beds or seams because of subsequent exposure to elevated temperatures and pressures in a harder form Coal can be considered a metamorphic rock, such as anthracite. Coal is mainly composed of carbon, together with varying amounts of other elements, mainly hydrogen, sulfur, oxygen and nitrogen. Historically, coal has been used as an energy resource, mainly Combustion is used to produce electricity and / or heat, and can also be used for industrial purposes, such as refining metals, or producing fertilizers and many chemical products. [0003] At present, the coal drying devices for power plants on the market cannot heat the coal evenly, and because most of the coal used ...
