[0017] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0018] Example 1
[0019] like Figure 1-Figure 4 A coal storage and transportation system for a thermal power plant includes a coal shed 1 and a coal bunker 4. A shed door 101 is provided on the front side of the coal shed 1. A coal unloading ditch 2 is provided in the coal shed 1. A first conveyor 3 is provided below the coal unloading ditch 2. The feeding end of the first conveyor 3 is located underground where the coal shed 1 is located, and the discharging end is located on the ground outside the coal shed 1. It also includes a coal crusher 5, which is located outside the coal shed 1, and the discharging end of the first conveyor 3 is located above the feeding port of the coal crusher 5. The first conveyor 3 is used to transport materials to the coal crusher 5, and the coal crusher 5 is used to discharge the crushed materials into the coal bunker 4. An atomizer cannon 6 is provided on the side of the coal unloading ditch 2, and a humidifying nozzle 7 is provided at the feeding port of the coal crusher 5. The atomizer cannon 6 sprays water mist to suppress dust. The humidifying nozzle 7 suppresses dust with water mist on the one hand, and increases the moisture content of coal on the other hand, effectively suppressing the adverse effects of coal drying.
[0020] like Figure 3As shown, a micro mist nozzle 8 is provided on the top of the coal shed 1; the micro mist nozzle 8 can spray micron-level water mist to absorb fine dust and make the dust fall.
[0021] like Figure 1 and Figure 4 As shown, a car washing compartment 9 is provided on the outside of the coal shed 1, and the car washing compartment 9 is located in front of the shed door 101; the front and rear sides of the car washing compartment 9 are opened, and car washing nozzles 10 are provided on the top and left and right sides. A bottom plate 11 is provided at the bottom of the car washing compartment 9, and a drainage hole is provided on the bottom plate 11. A waste water tank 12 is provided under the bottom plate 11; the waste water recovered in the waste water tank 12 can be recycled.
[0022] like Figure 1 As shown, it also includes a coal storage area 13, a bucket wheel excavator 14 and a second conveyor 15. The coal storage area 13 is arranged in the coal shed 1.
