[0002] A desulfurization tower is a tower device for desulfurizing industrial waste gas. The desulfurization tower was originally most widely built with granite. It uses the principle of water film desulfurization and dust removal, also known as granite water film desulfurization dust collector, or hemp stone water film desulfurization dust collector. The flue gas enters the interior of the desulfurization tower from the flue inlet and rises along the height direction of the tower. At the same time, the water pump pumps the slurry from the slurry storage tank to the annular pipe spraying device, and sprays it downward through the nozzle, and mixes with the upward flowing flue gas to react, thereby desulfurizing sulfur dioxide in the flue gas and achieving the environmental protection purpose. And the desulfurization process of the annular pipe spraying device in the desulfurization tower is a very important chemical unit.

Then replace the nozzle 11, thus achieving the effect that the annular pipe spraying device for the desulfurization tower 6 spraying is convenient for single installation and disassembly of the spraying. Embodiment 2

[0029] An annular pipe spraying device for the desulfurization tower 6 spraying. The water outlet end of the second water outlet pipe 3 is provided with a nozzle 11. The outer surface of the nozzle 11 is rotatably connected with a connecting pipe 23. The outer surface of the connecting pipe 23 is provided with a nozzle 24. The inside of the nozzle 24 is provided with a second baffle. The inside of the second baffle is provided with a plurality of first water outlet holes, which are evenly distributed inside the second baffle. The top of the second baffle is provided with a sleeve 26. The inside of the sleeve 26 is clamped with a thimble 28. The inside of the sleeve 26 is provided with a second spring 27. One end of the second spring 27 is arranged at the bottom of the sleeve 26, and the other end of the second spring 27 is arranged at the bottom of the thimble 28. The water outlet end of the nozzle 24 is provided with a second water outlet hole 25, and the inner diameter of the second water outlet is adapted to the diameter of the thimble 28.

[0030] In order to achieve the effect that the annular pipe spraying device for the desulfurization tower 6 spraying has the function of preventing the water outlet holes of the nozzle 24 and expanding the spraying range, as shown in the appendix Figures 5-7As shown in the figure, the present application adopts the following structure. Through the cooperation of the thimble 28, the second spring 27, the annular pipe 1, the first water outlet pipe 7, the second water outlet pipe 3, the nozzle 11, the connecting pipe 23 and the nozzle 24, during the use process, when the desulfurization tower 6 stops working, the gas inside the desulfurization tower 6 cannot quickly and completely disperse, and the solid particles in the gas are likely to adhere to the second water outlet hole 25 of the nozzle 24, causing blockage of the second water outlet hole 25. Therefore, when the desulfurization tower 6 and the nozzle 11 stop working, the thimble 28 and the second spring 27 are no longer under the pressure of water. The second spring 27 releases its elastic force and pushes the thimble 28, causing the thimble 28 to insert into the second water outlet hole 25, preventing solid particles from adhering to the second water outlet hole 25 and preventing the second water outlet hole 25 from being blocked; when the nozzle 11 works, the liquid sequentially passes through the annular pipe 1, the first water outlet pipe 7, and the second water outlet pipe 3 and enters the inside of the nozzle 11, the connecting pipe 23 and the nozzle 24, and enters above the second baffle through the first water outlet hole. Under the action of water pressure, the thimble 28 is subjected to pressure to squeeze the second spring 27 and disengages from the second water outlet hole, and the liquid sprays out from the second water hole. When the liquid sprays out, it will give the nozzle 24 a thrust in the direction opposite to the direction of the sprayed water, so that the nozzle 24 and the connecting pipe 23 rotate around the center line of the nozzle 11, thereby expanding the spraying range of the nozzle 24, and thus the ring pipe spraying device for the desulfurization tower 6 has the effects of preventing the water outlet holes of the nozzle 24 from being blocked and expanding the spraying range.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
