Improved fuel processing device for thermal power plant

Abstract

The invention relates to an improved fuel processing device for a thermal power plant. The device a box body and a driving structure I, the top of the box body is provided with a feed inlet, and the side wall of the lower part of the box body is provided with a discharge outlet; a rubbing and grinding crushing structure and a grinding device are sequentially arranged in the box body from top to bottom, the rubbing and grinding crushing structure comprises a supporting body, the supporting body is fixed in the position, below the feed inlet, of the box body, and a groove seam penetrating through the supporting body is formed at the top of the supporting body; and two supporting plates are oppositely arranged in the groove seam through a guide structure, and a plurality of crushing heads are evenly distributed on the opposite faces of the two supporting plates. The driving structure I is arranged outside the box body and used for driving the two supporting plates to horizontally reciprocate in the groove seam through the guide structure, and the movement directions of the two supporting plates are always opposite. The device improves the processing efficiency of coal briquettes by arranging the rubbing and grinding crushing structure, improves the processing effect, prolongs the service life of the grinding structure, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of fuel processing, in particular to an improved fuel processing device for thermal power plants. Background technique [0002] Thermal power refers to the conversion of heat energy generated by the combustion of solid and liquid fuels such as coal, oil, and natural gas into kinetic energy to produce electricity. [0003] In recent years, my country's development speed has been greatly accelerated, and the power consumption is also very large. Conventional wind power and hydropower generation cannot fully support the electricity consumption in the eastern region of my country. Therefore, thermal power generation is also a part of my country's power demand. However, thermal power generation mostly uses coal as fuel. At the same time, the coal needs to be processed. Because the pulverized coal furnace for power generation needs to grind the coal into irregular fine coal particles, the existing coal mills first ...

[0003] In recent years, my country's development speed has been greatly accelerated, and the power consumption is also very large. Conventional wind power and hydropower generation cannot fully support the electricity consumption in the eastern region of my country. Therefore, thermal power generation is also a part of my country's power demand. However, thermal power generation mostly uses coal as fuel. At the same time, the coal needs to be processed. Because the pulverized coal furnace for power generation needs to grind the coal into irregular fine coal particles, the existing coal mills first crush the coal and then grind it. The crushed coal is still relatively large, and directly crushing the crushed coal will not only affect the grinding efficiency, but also greatly affect the life of the grinding structure
