Embodiment Construction

[0010] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] The structure of the present invention is as figure 1 As shown, it mainly consists of pulverized coal burner 1, pulverized coal combustion furnace 2, coal sliding pipe 3, rotary dryer 4, mill (Raymond mill, ball mill, vertical mill, column mill) 5, hoist 8 Form with pulverized coal bin 9. Wherein: pulverized coal burner 1, pulverized coal combustion furnace 2, rotary dryer 4, mill 5, hoist 8 and pulverized coal bin 9 are connected in sequence, and coal sliding pipe 3 is connected with rotary dryer 4. The pulverized coal burner 1 sprays the pulverized coal into the pulverized coal combustion furnace 2 for combustion, and the heat enters the rotary dryer 4 to dry the coal that enters the rotary dryer 4 through the coal slidi...

Abstract

The invention discloses a pulverized coal preparation device based on a pulverized coal combustion furnace, a rotary dryer and a mill, comprising a pulverized coal combustor, a pulverized coal combustion furnace, a coal feeding pipe, a rotary dryer, a mill, an elevator and a pulverized coal bin, wherein the pulverized coal combustor, the pulverized coal combustion furnace, the rotary dryer, the miller, the elevator and the pulverized coal bin are successively connected; the coal feeding pipe is communicated with the rotary dryer; the pulverized coal combustor injects the pulverized coal into the pulverized coal combustion furnace to be combusted; heat enters the rotary dryer to dry the coal entering the rotary dryer from the coal feeding pipe; the dried coal is ground in the mill; and the ground pulverized coal enters the elevator and is elevated into the pulverized coal bin.

Description

technical field [0001] The invention is a pulverized coal preparation device based on a pulverized coal combustion furnace, a rotary dryer and a mill. Background technique [0002] At present, my country's main energy is still dominated by coal. Except for large-scale power stations and power plants that use advanced pulverized coal combustion technology (the burnout rate of pulverized coal is as high as 99%), others are still dominated by traditional chain grates and fluidized fluidized furnaces. The chain grate burnout rate is less than 85%, which wastes energy and seriously pollutes the environment. Combustion of pulverized coal is energy-saving and environmentally friendly, and it is a general trend of social development. However, the existing coal grinding device has complex structure, inconvenient operation, and it is difficult to realize automatic control. Contents of the invention [0003] The invention provides a pulverized coal preparation device based on a pulv...
