Thus, the whole device achieves the advantage of good purification effect.

[0004] However, there is still room for improvement in this device. In order to further improve the dust reduction effect of spraying, a waste salt high-temperature melting waste gas treatment device is provided that can make the waste gas and spray liquid mix more thoroughly. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1

[0026] Reference Figure 1-4 A waste salt high-temperature melting waste gas treatment device includes a spray tower 1, a storage tank 2, and a filter box 3. The storage tank 2 is connected to the spray tower 1 through a liquid supply pipe 21 to provide spray liquid to the spray tower 1. An air inlet pipe 12 is provided on the side wall of the spray tower 1 near the bottom. A valve 121 is provided on the air inlet pipe 12. The waste gas generated during the melting and recycling of sodium chloride waste salt will enter the spray tower 1 through the air inlet pipe 12. The filter box 3 is connected to the upper part of the spray tower 1 through an air outlet pipe 31. After being sprayed and dusted, the waste gas enters the filter box 3 for further adsorption treatment.

[0027] The end of the infusion pipe 21 passes through the top of the spray tower 1 and enters the interior of the spray tower 1. The end of the infusion pipe 21 is provided with a connector 14 and is rotatably connected to one end of the connector 14. The other end of the connector 14 is fixedly connected to a rotating pipe 15. An annular pipe 152 is provided on the rotating pipe 15 through a connecting pipe 151. An atomizing nozzle 153 is provided at equal angles on the annular pipe 152. The spray liquid enters the rotating pipe 15 from the infusion pipe 21, then enters the annular pipe 152 through the connecting pipe 151, and is sprayed out from the atomizing nozzle 153.

[0028] The inner wall of the spray tower 1 is provided with a spiral guide groove 13 near the bottom. The air inlet pipe 12 is located inside the spray tower 1 with one end facing the entrance of the spiral guide groove 13. After the exhaust gas enters the spiral guide groove 13 and is guided by the spiral guide groove 13, it spirals upward, which can prolong the path of the exhaust gas in the spray tower 1 and the time it stays in the spray tower 1, so that the exhaust gas and the spray liquid are mixed more thoroughly and the dust in the exhaust gas can be removed more effectively.

[0029] Furthermore, a large gear 142 is fixedly connected to the side wall of the connector 14, and a small gear 143 is rotatably connected to the top of the inner wall of the spray tower 1. The small gear 143 meshes with the large gear 142. A motor 144 is provided at the top of the spray tower 1. The output end of the motor 144 is fixedly connected to the gear shaft of the small gear 143. When the motor 144 is started, it can drive the annular tube 152 to rotate through the meshing connection between the small gear 143 and the large gear 142, thereby driving the atomizing nozzle 153 to rotate. This causes the spray liquid to spiral down, and the direction of the spiral is opposite to the direction of the exhaust gas spiraling up, which can further improve the spraying effect.

[0030] Furthermore, a pressure pump 211 is provided on the infusion pipe 21 to pump the spray liquid into the annular pipe 152 and provide a certain pressure.

[0031] Furthermore, the bottom of the spray tower 1 is provided with a liquid outlet 11, and a solenoid valve 111 is provided on the liquid outlet 11. When a certain amount of liquid accumulates inside the spray tower, the valve 121 is closed and the solenoid valve 111 is opened to discharge the liquid from the spray tower 1.

[0032] Furthermore, the filter box 3 is equipped with a filter plate 32 and an activated carbon plate 33 to further filter the exhaust gas after spraying.

[0033] Working principle: During the melting and recycling of sodium chloride waste salt, the waste gas generated enters the spray tower 1 through the inlet pipe 12. After being guided by the spiral guide groove 13, it spirals upward, which can prolong the path of the waste gas in the spray tower 1 and the time it stays in the spray tower 1. The pressure pump 211 is started, and the spray liquid enters the rotating pipe 151 through the liquid delivery pipe 21, and then enters the annular pipe 152 and is sprayed out from the atomizing nozzle 153. The motor 144 is started, and the small gear 143 meshes with the large gear 142 to drive the annular pipe 152 to rotate, thereby driving the atomizing nozzle 153 to rotate. This causes the spray liquid to spiral downward, and the spiral direction is opposite to the spiral upward direction of the waste gas, so that the waste gas and the spray liquid are mixed more thoroughly, which can more effectively remove dust from the waste gas. After being sprayed, the waste gas enters the filter box 3 for filtration.
