[0026] As Figure 1And Figure 2 As shown in the figure, the present application provides a coal-fired catalyst spraying device, comprising a base 1, a liquid storage tank 2 and a delivery pump 3 are arranged on the base 1, a mounting bracket 4 is rotatably arranged on the base 1, a drive motor 5 is arranged on the base 1 to drive the mounting bracket 4 to rotate, a mounting assembly 6 is arranged on the mounting bracket 4, a nozzle 7 is arranged on the mounting assembly 6, the liquid storage tank 2 is connected with the delivery pump 3 through a first pipeline 8, the delivery pump 3 is connected with a conversion head 10 through a second pipeline 9, the conversion head 10 is connected with the nozzle 7 through a flexible pipeline 11, the arrangement of the conversion head 10 can realize the conversion and adaptation of pipeline connection, so that different specifications of pipelines can be smoothly connected, the flexible pipeline 11 can absorb the stress and displacement change generated when the mounting bracket 4 rotates, avoiding damage or breakage due to frequent rotation, by arranging the mounting bracket 4 on the base 1 and configuring the drive motor 5, the mounting bracket 4 can drive the nozzle 7 to realize multi-angle rotation, the liquid storage tank 2 stores catalyst solution, which is powered by the delivery pump 3, the solution is delivered from the liquid storage tank 2 to the delivery pump 3 through the first pipeline 8, then the solution is sent to the conversion head 10 by the delivery pump 3 through the second pipeline 9, and finally flows through the flexible pipeline 11 and the nozzle 7, and is sprayed by the nozzle 7. Compared with the traditional fixed-angle spraying device, the spraying device can flexibly adjust the angle of the nozzle 7, better adapt to complex working environment, increase the spraying area, and make the catalyst play a more full role in the coal combustion process, promoting more efficient combustion of coal.

[0027] As shown in the figure, Figure 3 The mounting assembly 6 comprises a threaded column 61, a locking nut 62 and a mounting block 63, the mounting block 63 is fixedly arranged at one end of the threaded column 61, the nozzle 7 is mounted on the mounting block 63, the mounting bracket 4 is provided with a through hole 41, the end of the threaded column 61 away from the mounting block 63 penetrates through the through hole 41, and the locking nut 62 is threadedly connected with the threaded column 61 to lock the mounting assembly 6 on the mounting bracket 4. Specifically, the locking nut 62 is threadedly connected with the threaded column 61, during installation, the end of the threaded column 61 away from the mounting block 63 is smoothly penetrated through the through hole 41 on the mounting bracket 4, then the locking nut 62 is screwed on the threaded column 61 and gradually tightened, which can quickly and firmly fix the mounting assembly 6 on the mounting bracket 4, saving installation time.

[0028] As shown in the figure, Figure 1 And Figure 2 The through hole 41 is a waist-shaped hole, the long axis direction of the through hole 41 provides a moving space for the threaded column 61, so that the position of the threaded column 61 in the through hole 41 can be adjusted to a certain extent. During installation of the nozzle 7, the position of the threaded column 61 can be finely adjusted in the long axis direction of the through hole 41 according to actual needs, so as to realize accurate adjustment of the position of the nozzle 7.

[0029] As shown in the figure, Figure 1 And Figure 2As shown, there are multiple mounting components 6 and multiple flexible pipes 11. Each flexible pipe 11 corresponds to a nozzle 7 on the mounting component 6. Each nozzle 7 on the mounting component 6 independently delivers catalyst solution through its corresponding flexible pipe 11. This allows each nozzle 7 to perform spraying operations independently, enabling a wider spraying range. In this embodiment, there are 3 mounting components 6, 3 flexible pipes 11, and 3 corresponding nozzles 7.

[0030] like Figure 1 As shown, a control valve 12 is installed on the flexible pipe 11. The control valve 12 can precisely adjust the flow rate of the catalyst solution in the flexible pipe 11 according to the actual working conditions. For example, when the calorific value of the coal is low and the combustion rate is slow, the flow rate can be reduced by the control valve 12 to allow the catalyst to react more fully with the coal and improve the combustion efficiency. When the calorific value of the coal is high and the combustion rate is fast, the flow rate can be appropriately increased to ensure that the supply of catalyst can keep up with the combustion demand and maintain a good combustion effect.

[0031] like Figure 1 and Figure 2 As shown, nozzle 7 is an atomizing nozzle. The atomizing nozzle can break the coal catalyst solution into tiny droplets to form a mist spray. Compared with the traditional large droplet or columnar spray, it can cover the coal surface more evenly and increase the contact area between the catalyst and the coal.

[0032] like Figure 2 As shown, a scale 13 is provided on one side of the through hole 41. When the mounting component 6 is installed by engaging the through hole 41 with the threaded post 61, the scale 13 provides the operator with a clear positional reference. The operator can accurately place the threaded post 61 at a specific position in the through hole 41 according to actual needs. For example, when multiple nozzles 7 need to be arranged at equal or specific intervals, the position of each mounting component 6 on the mounting frame 4 can be accurately adjusted by referring to the scale 13 to ensure that the spacing between the nozzles 7 meets the design requirements, thereby achieving uniform and accurate spraying of the catalyst on the coal surface and improving the consistency and stability of the catalytic effect.

[0033] In this embodiment, the first pipe 8 and the second pipe 9 are rigid pipes, preferably cast iron pipes with an anti-corrosion layer.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
