[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method:

[0023] Figure 1-4A spray gun with a rotatable spray head is shown, comprising spray gun 1 and spray gun 2, the side ends of spray gun 1 and spray gun 2 are fixedly connected to the same vertical plate 3, the ends of spray gun 1 and spray gun 2 away from the vertical plate 3 are both provided with hoses 4, the side ends of hoses 4 are provided with spray heads 5, the upper end of spray gun 1 and the lower end of spray gun 2 are both fixedly connected to fixed frames 6, a limiting groove 7 is provided at one end of the fixed frame 6 close to the spray head 5, a vertical pipe 8 is fixedly connected to one end of the spray head 5 close to the fixed frame 6, a compression spring 9 is fixedly connected to the interior of the vertical pipe 8, one end of the compression spring 9 is fixedly connected to an extrusion block 10, and the extrusion block 10 is away from the compression spring 9. One end of the spring 9 is fixedly connected to a limit block 11 which is slidably connected to the limit groove 7. A thermometer 18 is provided on the side ends of the spray gun 1 and the spray gun 2. The inner diameter of the tube body of the spray gun 1 is smaller than the inner diameter of the tube body of the spray gun 2. The side end of the vertical plate 3 is fixedly connected to a hand-held frame 13. The hand-held frame 13 is used to facilitate personnel to hold the spray gun. The aperture of the nozzle 5 provided on the spray gun 1 is smaller than the aperture of the nozzle 5 provided on the spray gun 2. The lower end of the spray gun 1 and the upper end of the spray gun 2 are both provided with an injection pipe 12. The inner diameter of the hose 4 provided on the spray gun 1 is smaller than the inner diameter of the hose 4 provided on the spray gun 2.

[0024] This solution can be implemented. When in use, the thermometer 18 can be used to measure the temperature of the furnace body and the flue gas. At the same time, the liquid and solid to treat the flue gas need to be injected into the spray gun 1 and the spray gun 2 through the injection pipe 12 respectively. The spray gun 1 or the spray gun 2 can be selected to treat the flue gas. When treating the flue gas, the limit block 11 can be moved to push the extrusion block 10 to continue to squeeze the compression spring 9 until one end of the extrusion block 10 is moved out of the limit groove 7. Then, the nozzle 5 is rotated to adjust its angle in the horizontal direction. After adjusting it to a suitable angle, one end of the limit block 11 is reset to prevent the nozzle 5 from moving in the horizontal direction. Therefore, the spray gun can adjust the angle of the nozzle 5 in the horizontal direction, which is convenient for personnel to spray the flue gas at multiple angles in the horizontal direction.

[0025] The second implementation method:

[0026] Based on the first embodiment, this embodiment adds structures such as a soft protective tube 14, and the rest of the parts remain the same as the first embodiment.

[0027] Figure 5-6 It is shown that a soft protective tube 14 is sleeved on the outer end of the hose 4, a first magnetic block 15 is fixedly connected to the inner wall of one side of the soft protective tube 14, a second magnetic block 16 that attracts the first magnetic block 15 is fixedly connected to the inner wall of the other side of the soft protective tube 14, and two pairs of force blocks 17 are fixedly connected to the side ends of the soft protective tube 14.

[0028] This solution can be achieved by pinching the force block 17 during the use of the hose 4, pulling the two pairs of force blocks 17 to the side away from each other, thereby pulling the soft protective tube 14 open, and then covering the soft protective tube 14 on the hose 4, so that the first magnetic block 15 and the second magnetic block 16 are in contact and adsorbed together, thereby improving the stability of the opening of the soft protective tube 14, and utilizing the soft protective tube 14 to protect the hose 4 from foreign objects touching and puncturing the hose 4, thereby enabling the nozzle 5 to smoothly spray objects that process smoke.

[0029] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
