Description

Technical Field

[0001] The present invention relates to the technical field of coal conveying temperature measurement, and specifically to a coke spraying cooling system. Background Art

[0002] Coke is a type of solid fuel obtained by dry distillation of coal at a high temperature of about 1000 °C. The main component is fixed carbon. After processing, the coke enters the dry quenching furnace at a temperature of about 1000 °C, and after being cooled in the dry quenching furnace, the temperature drops below 200 °C and is discharged, and is output by the coke conveying belt. The cooled coke may also have high-temperature coke discharged due to uneven cooling. In particular, the red coke in the high-temperature coke, if not processed in time, will cause damage to the coke conveying belt.

[0051] The present invention elaborates on the pipe diameter size in detail through Embodiment 2.

[0052] On one side of the coke conveyor belt 11, the main production water pipe is arranged in the present invention, with a pipe diameter of DN25mm.
