Solid waste disposal device for power plant

Abstract

The invention provides a solid waste disposal device for a power plant. The solid waste disposal device for the power plant comprises a device shell, an ash inlet, a motor, a driving shaft, a heat recycling barrel, grinding plates, a grinding groove and grinding blades. The device shell is a cylinder, and the ash inlet is fixedly connected with the side edge of the top of the device shell. The motor is fixedly connected to the middle of the top of the device shell. A water cooling outer box is fixedly connected with the periphery of the side edge of the device shell. A water spray box is fixedly connected with the upper part of the interior of the device shell. Groove cleaning blades are rotationally connected with the lower part of the water spray box. The grinding plates are fixedly connected with the lower parts of the groove cleaning blades. Fan blades are rotationally connected with the lower parts of the grinding plates. The heat recycling barrel is fixedly connected with the position below the fan blades. A scrap collection chamber is arranged below the heat recycling barrel. A scrap outlet is arranged on the lower part of the scrap collection chamber. According to the solidwaste disposal device for the power plant, ashes are crushed by the grinding blades, and in the crushing process, because of water spray, no dust is generated while the temperature can be lowered, heat can be blown to the heat recycling barrel in the rotating process of the blades, and residual heat of the ashes can be recycled through a water pipe in the barrel.

Description

technical field [0001] The invention relates to a waste treatment device, in particular to a power plant solid waste treatment device. Background technique [0002] Boiler ash refers to the final product formed after the minerals in the coal undergo certain physical and chemical changes under the high temperature caused by the combustion in the furnace. Since ash in the boiler will cause problems such as contamination, slagging, corrosion and wear of the heating surface in the furnace, which will affect the normal operation of the boiler, the ash and slag must be removed effectively and in a timely manner. Part of the ash is discharged from the slag hopper behind the grate of the layer-fired furnace, the cold ash hopper at the lower part of the pulverized coal furnace hearth, or the slag outlet and slag well at the bottom of the liquid slag discharge furnace, which is called slag discharge. The slag needs to be transported to the slag yard (or ash pool) by a boiler slag dis...
