[0020] like Figure 1-Figure 3 As shown, a device for energy saving and emission reduction by adding catalyst to coal-fired boiler comprises a shell 1; a storage box 2 is fixedly connected to the top of the shell 1; a conveyor belt 3 is installed inside the shell 1; a liquid tank 4 is fixedly connected to the inner side wall of the bottom end of the shell 1; a conveying cavity 15 is opened inside the shell 1, and the conveying cavity 15 is communicated with the liquid tank 4; an electric slide rail 5 is fixedly connected to the inner side wall of the top end of the shell 1; a connecting slider 6 is slidably connected to the bottom end of the electric slide rail 5; a telescopic hose 7 is connected between the connecting slider 6 and the liquid tank 4; and a conveying pipe 8 is connected to the bottom end of the telescopic hose 7.

[0021] During work, the staff puts the coal on the conveyor belt 3, and the coal is transported to the inside of the shell 1 through the conveyor belt 3. The catalyst is stored in the storage box 2. The catalyst inside the storage box 2 is transported to the inside of the liquid tank 4 through the conveying chamber 15. The connecting slider 6 is slid by the electric slide rail 5, and the sliding of the connecting slider 6 causes the conveying pipe 8 to slide together.

The catalyst inside the liquid tank 4 will be transported to the connecting slider 6 through the telescopic hose 7. The telescopic hose 7 is made of a telescopic hose material. The sliding of the connecting slider 6 will not affect the normal use of the telescopic hose 7, and then it will be sprayed on the coal on the conveyor belt 3 through the conveying pipe 8, and the movement of the conveying pipe 8 will improve the spraying uniformity of the coal.

[0022] A positioning plate 13 is fixedly connected to the side end of the housing 1 ; a plurality of groups of spray heads 14 are fixedly connected to the bottom end of the positioning plate 13 , and the spray heads 14 are arranged above the conveyor belt 3 .

[0023] When the coal on the conveyor belt 3 is transported out of the shell 1, the catalyst inside the storage box 2 is transported to the spray head 14 through the positioning plate 13. The spray head 14 sprays the catalyst onto the conveyor belt 3 to ensure the uniformity of the coal catalyst, thereby improving the energy-saving and emission-reduction effect of the boiler coal.

[0024] The conveying pipes 8 are installed in multiple groups inside the shell 1 , and both sides of the conveying belt 3 are arranged on the inner wall of the shell 1 .

[0025] The conveying pipe 8 and the nozzle 9 can swing the position of the coal on the conveyor belt 3 to confuse the position of the coal, so that the coal below can also absorb the catalyst. The conveyor belt 3 is inside the shell 1, and the shell 1 can limit the position of the coal on the conveyor belt 3 to prevent the conveying pipe 8 and the nozzle 9 from swinging and falling away from the conveyor belt 3. Multiple groups of conveying pipes 8 and nozzles 9 can improve the uniformity of the coal.

[0026] The outer wall of the conveying pipe 8 is fixedly connected with a spray plate 11, and the spray plate 11 is arranged above the conveying belt 3; the bottom end of the conveying pipe 8 is fixedly connected with a spray head 9.

[0027] The bottom end of the conveying pipe 8 is connected to a nozzle 9, which is provided with a plurality of holes.

The catalyst can be sprayed onto the conveyor belt 3 through the spray disk 11. A plurality of groups of conveying pipes 8 are provided inside the shell 1. After the conveying pipes 8 swing to the coal burning position, the catalyst is evenly sprayed through the spray disk 11.

[0028] A connecting pipe 12 is fixedly connected to the bottom end of the connecting slide block 6 ; and a conveying pipe 8 is threadedly connected to the bottom end of the connecting pipe 12 .

[0029] When the delivery pipe 8 and the nozzle 9 need regular maintenance, the delivery pipe 8 and the connecting pipe 12 are threadedly connected. After suspending work, the delivery pipe 8 and the connecting pipe 12 are rotated to separate them, thereby facilitating maintenance of the delivery pipe 8.

[0030] The bottom end of the nozzle 9 is fixedly connected with a plurality of groups of balls 10 , and the balls 10 are arranged above the conveyor belt 3 .

The catalyst can be sprayed onto the conveyor belt 3 through the spray disc 11. The interior of the shell 1 is provided with a plurality of groups of conveying pipes 8. After the conveying pipes 8 swing the coal position, The catalyst is sprayed evenly through the spray disc 11; a ball 10 is provided at the bottom end of the nozzle 9, and the bottom end of the nozzle 9 will contact the conveyor belt 3 and the coal. The rolling of the ball 10 can facilitate the movement of the nozzle 9, thereby facilitating the normal movement of the connecting slider 6, and ensuring the swing and spraying of the coal by the nozzle 9; when the conveying pipe 8 and the nozzle 9 need regular maintenance, the conveying pipe 8 and the connecting pipe 12 are threadedly connected. After suspending work, the conveying pipe 8 is rotated to separate the connecting pipe 12, so as to facilitate the maintenance of the conveying pipe 8; the conveying pipe 8 and the nozzle 9 can swing the position of the coal on the conveyor belt 3, so that The chaotic position of the coal can also allow the coal below to absorb the catalyst. The conveyor belt 3 is inside the shell 1. The shell 1 can limit the position of the coal on the conveyor belt 3 to prevent the conveying pipe 8 and the nozzle 9 from swinging and falling away from the conveyor belt 3. Multiple groups of conveying pipes 8 and nozzles 9 can improve the uniformity of the coal; when the coal on the conveyor belt 3 is transported out of the shell 1, the catalyst inside the storage box 2 is transported to the spray head 14 through the positioning plate 13. The spray head 14 will spray the catalyst onto the conveyor belt 3 to ensure the uniformity of the coal catalyst, thereby improving the energy-saving and emission reduction effect of boiler coal burning.
