Recycling wastewater is conducive to energy conservation and emission reduction. The wastewater after desulfurization treatment is used to adjust the humidity of coal piles or other ash systems. The wastewater after desulfurization treatment is still high-salt wastewater and contains a large amount of chloride ions, which will cause serious pollution when it is released to the surrounding environment.

[0004] Since the wastewater sprayed from the inside of the atomizing nozzle is from a thermal power plant, the wastewater contains impurities. Since the diameter of the nozzle of the atomizing nozzle is small, the impurities in the wastewater can easily clog the atomizing nozzle, affecting its spray effect. In addition, it is inconvenient to adjust the direction of the atomizing nozzle according to the direction of the spray, which reduces its practicality. Utility Model Content

The position on the sealing cover 5 corresponding to the first connecting pipe 3 is connected to the water pipe 11.

[0031] Specifically, the external thermal power plant wastewater is transported to the interior of the atomizing nozzle 1 through the water pipe 11, the corresponding second connecting pipe 8, the first connecting pipe 3 and the telescopic pipe 2. At the same time, the filter 10 installed inside the second connecting pipe 8 prevents impurities in the wastewater from entering the interior of the atomizing nozzle 1, preventing the impurities from clogging the atomizing nozzle 1 and affecting the spray effect of the atomizing nozzle 1.

[0032] See also Figure 1 and Figure 2 A first rotating shaft 12 is fixedly connected to the round seat 6, and a first motor 13 is installed on the top of the sealing cover 5. The output end of the first motor 13 is connected to the top of the first rotating shaft 12 to drive the round seat 6 to rotate. The bottom end of the round seat 6 is connected to a fixed pipe 14, and a first solenoid valve 15 is installed on the fixed pipe 14. The fixed pipe 14 is connected to the atomizing nozzle 1 through a hose 16, so that the water inside the atomizing nozzle 1 flows to the bottom side of the cylinder 4.

[0033] Specifically, when there are many impurities on the filter 10, the first motor 13 drives the round seat 6 to rotate, so that a second connecting pipe 8 is connected with the fixed pipe 14 and the drain pipe 17.

When passing through the atomizing nozzle 1, the wastewater is sprayed into a mist onto the corresponding pile. At the same time, the filter screen 10 installed inside the second connecting pipe 8 prevents impurities in the wastewater from entering the interior of the atomizing nozzle 1, thereby preventing the impurities from clogging the atomizing nozzle 1.
