As described in the background art, usually, stone coal is directly transported as waste to the outside of the thermal power plant for disposal. The coal particles mixed in the stone coal can not be effectively utilized, and the resource waste is caused.
In order to improve the above problems, referring to fig. 1, 2 and 3, there is provided a pebble coal recycling apparatus including a dry type slag extractor 110, a pebble coal hopper 120, a pebble coal temporary storage tank 130 and a medium speed coal mill 150. Wherein the dry type slag extractor 110 is provided with a slag inlet 111, a slag outlet 112, a cold air inlet 113 and a hot air outlet 114. The hot air outlet 114 communicates with the furnace. The high-temperature slag at 800-900 ℃ falls onto the steel conveyor belt of the dry slag extractor 110 through the slag inlet 111, and the slag is conveyed to the slag outlet 112 by the steel conveyor belt. The cold air inflow port 113 at 0-30 ℃ enters the dry slag extractor 110 through the cold air inflow port 113, and the flowing direction is opposite to the conveying direction of the high-temperature slag. In the dry slag extractor 110, the cold air and the high-temperature slag are fully heat-exchanged and then are converted into hot air at 290-300 ℃, and the hot air flows through the hot air outlet 114 and then enters the hearth, so that the heat loss of the boiler is reduced, and the efficiency of the boiler is improved. The cooling air quantity accounts for about l% of the total air quantity of the boiler, so that the normal operation of the boiler is not influenced. While slag cooled to 140-160 ℃ is discharged from the slag discharge port 112. The pebble coal hopper 120 has a hollow structure, and the bottom surface thereof is inclined so that pebble coal in the pebble coal hopper 120 flows out. The pebble coal hopper 120 is provided with a pebble coal inlet 121 at the top end thereof so that pebble coal flows into the pebble coal hopper 120. The bottom of the pebble coal feed port is provided with a pebble coal conveying pipe 122, and the pebble coal conveying pipe 122 is communicated with the slag inlet 111 of the dry slag extractor 110.

The medium speed coal mill 150 is capable of processing coarse coal, and its outlet communicates with the pebble coal temporary storage tank 130, and is capable of discharging pebble coal into the pebble coal temporary storage chamber. In the whole, the stone coal is transferred to the high-temperature slag in the dry slag extractor 110 by means of the stone coal temporary storage box 130 and the stone coal hopper 120, so that coal particles mixed in the stone coal can be effectively utilized, the heat energy generated by burning the coal materials mixed in the stone coal can further improve the temperature of hot air supplied into a hearth, resources are saved, heat energy is recycled by a boiler, and the economic benefit of the stone coal is improved. In addition, the place where the stone coal burns is the dry slag extractor 110 originally possessed by the thermal power plant, so that new equipment is not required to be purchased, and the equipment purchasing cost is saved.
Preferably, in the illustrated example, the pebble coal transporting pipe 122 is disposed at one side of the pebble coal hopper 120, and it is more advantageous for the pebble coal to slowly flow out, compared to the form in which the pebble coal transporting pipe 122 is disposed at the middle of the bottom of the pebble coal hopper 120, so that the pebble coal can be more uniformly spread on the moving high temperature slag.
