[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] refer to Figure 1-2 As shown, the utility model provides a nozzle suitable for online maintenance of an activated carbon thermal regeneration system, comprising: an equipment body 1 with an activated carbon module, a plurality of nozzles are arranged in a ring array above the activated carbon module, a sleeve 2 is penetrated inwardly from the outside of the equipment body 1, a piston 13 detachably connected to one end of the nozzle is arranged in the sleeve 2, a driving member for driving the piston 13 to perform axial reciprocating movement in the sleeve 2 is arranged at the end of the piston 13 away from the nozzle 12, and a liquid supply mechanism for supplying liquid to the nozzle 12 is arranged on the outside of the equipment body 1.

[0027] As described above, when using the device body 1, multiple nozzles, sleeve 2, piston 13, and driving member provided by the utility model, the piston 13 provides an installation position for the nozzle 12 at one end of the liquid supply mechanism, and the driving member is used to facilitate the position adjustment of the piston 13 in the sleeve 2, so that the nozzle 12 can be taken out of the device body 1 or placed into the device body 1, and the nozzle 12 is supplied with liquid through the liquid supply mechanism.

[0028] Further, in order to facilitate the adjustment of the position of the piston 13 in the sleeve 2, refer to Figure 3As shown, the driving mechanism includes a plug 3 and a pull rod 15. The pull rod 15 is arranged at the end of the piston 13 away from the nozzle 12. The plug 3 is sleeved on the liquid supply mechanism, and one end of the plug 3 is screwed to the end of the sleeve 2. The end of the pull rod 15 away from the piston 13 can abut on the plug 3. When the plug 3 is screwed to the end of the sleeve 2, one end of the pull rod 15 abuts on the plug 3, so that the piston 13 is easy to abut in the sleeve 2, thereby preventing the piston 13 from being displaced. When the plug 3 is removed, the piston 13 is easily pulled out or pushed in from the sleeve 2 through the pull rod 15, so that the position of the piston 13 is easy to adjust.

[0029] Further, in order to facilitate the connection between the nozzle 12 and the liquid supply mechanism and to install it on the piston 13, refer to Figure 3-4 As shown, a through hole 14 is also provided in the axial direction of the piston 13, and the nozzle 12 and one end of the liquid supply mechanism are detachably connected to the two ends of the through hole 14. The through hole 14 facilitates the liquid supply mechanism and the nozzle 12 to be detachably mounted on the two ends of the piston 13, respectively, so that the liquid supply mechanism can supply liquid to the nozzle 12 through the piston 13.

[0030] In the present utility model, combined with Figure 3-4 As shown, the device body 1 of this embodiment is also provided with a sealing plate 9 for sealing the end of the sleeve 2, and an adjustment mechanism is provided in the axial direction between the sealing plate 9 and the sleeve 2, and the adjustment mechanism is used to elastically adjust the length between the sealing plate 9 and the sleeve 2.

[0031] Combination Figure 4 As shown, the adjustment mechanism includes a retractable telescopic rod 8 and a sleeve 7. The sleeve 7 is arranged in parallel on one side of the end of the sleeve 2, and a mounting member 6 for connection is provided between the sleeve 7 and the sleeve 2. The end of the telescopic rod 8 facing away from the sleeve 7 is welded to the sealing plate 9, and an elastic member for elastic expansion and contraction is provided in the axial direction between the telescopic rod 8 and the sleeve 7.

[0032] As described above, when using the sealing plate 9 and the adjustment mechanism provided by the utility model, the sleeve 7 in the adjustment mechanism is arranged in parallel on one side of the sleeve 2 through the mounting member 6, and the telescopic rod 8 is automatically retracted on the sleeve 7 through the elastic member, so that the sealing plate 9 is abutted against the end of the sleeve 2 through the elastic force of the elastic member, thereby preventing the exhaust gas in the equipment body 1 from being discharged outward through the sleeve 2.

[0033] Further, in order to facilitate the telescopic rod 8 to be telescopic on the sleeve 7, refer to Figure 4 As shown, the elastic member includes a spring 16. The elastic force of the spring 16 allows the telescopic rod 8 to be telescoped on the sleeve 7, so as to facilitate automatic position adjustment of the sealing plate 9 on one side of the sleeve 2.

[0034] Furthermore, in order to prevent the sealing plate 9 from interfering with the nozzle, as shown in the reference figure, a nozzle is provided on the side of the nozzle 12 close to the abutment plate 10, and the nozzle is tilted downward. Since the abutment plate 10 and the sealing plate 9 are located on the side of the nozzle 12 away from the sleeve 2, the nozzle 12 is tilted to prevent the sealing plate 9 and the abutment plate 10 from interfering with the spraying of the nozzle 12.

[0035] In the present utility model, combined with Figure 3 As shown, the side of the nozzle 12 of this embodiment facing away from the piston 13 is also provided with an anti-collision abutment plate 10, and the side of the abutment plate 10 close to the nozzle 12 is provided with a support rod 11, one end of the support rod 11 can be detachably mounted on the piston 13, and one end of the abutment plate 10 abuts against the inner side of the sealing plate 9.

[0036] As mentioned above, when using the abutment plate 10 provided by the utility model, the abutment plate 10 is arranged on the side of the nozzle 12 close to the sealing plate 9 through the support rod 11. When the piston 13 enters the equipment body 1, the abutment plate 10 first abuts on the sealing plate 9, and the sealing plate 9 pushes the sleeve 2 to facilitate the nozzle 12 to be separated from the sleeve 2, so that the nozzle of the nozzle 12 is in the equipment body 1. During this process, the sealing plate 9 is prevented from directly acting on the nozzle 12.

[0037] Further, in order to facilitate the detachable installation of the support rod 11 on the piston 13, refer to Figure 4 As shown, a ball block 18 is provided at one end of the support rod 11 away from the abutment plate 10, and a ball groove 17 for accommodating a ball joint of the ball block 18 is provided on the piston 13. The support rod 11 is detachably connected to the ball groove 17 on the piston 13 through the ball block 18, so that the abutment plate 10 is conveniently arranged on the side of the spray head 12 close to the sealing plate 9, and when the ball block 18 is taken out of the ball groove 17, the spray head 12 is conveniently detachable from the piston 13.

[0038] In the present utility model, combined with Figure 1-3 As shown, the liquid supply mechanism of this embodiment includes a ring tube 5 and a plurality of hoses 4 connected and arranged on the ring tube 5. The ring tube 5 is arranged on the outer wall of the equipment body 1, and one end of the plurality of hoses 4 is detachably mounted on the corresponding through holes 14.

[0039] As described above, when the liquid supply mechanism provided by the utility model is used, the piston 13 is conveniently connected to the annular tube 5 through the hose 4 in the liquid supply mechanism, and the piston 13 can be conveniently taken out of or put into the sleeve 2 while the liquid is supplied to the spray head 12.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
