Description

Technical Field

[0001] The utility model relates to the field of drying tower spray guns, in particular to an anti-deformation mechanism for drying tower spray guns. Background Art

[0002] The anti-deformation mechanism of the drying tower spray gun is a supporting structure for strengthening the protection of the drying tower spray gun. The current mainstream wastewater zero-discharge treatment methods are rotary atomization and dual-fluid atomization. The dual-fluid flue gas evaporation atomization is to establish a drying tower in which the flue gas enters from the top of the tower. The desulfurization wastewater is sprayed into the tower through a spray gun, mixed with the high-temperature flue gas, and discharged with the flue gas after evaporation. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of the anti-deformation mechanism of the drying tower spray gun.

[0003] The existing anti-deformation mechanism of the drying tower spray gun has certain drawbacks when in use. Since the flue gas contains dust, ash blocks are formed on the spray gun rod and the nozzle and concentrated above the spray gun rod and the nozzle. The spray gun is deformed under the action of high temperature. After the spray gun is deformed, the sprayed mist water is not parallel to the center of the tower, and the angle deviation causes the mist water to sweep the tower wall, resulting in incomplete evaporation and discharge. Water accumulates at the bottom of the tower, and the drying tower cannot operate for a long time, which brings certain adverse effects to the actual use process. For this reason, we propose an anti-deformation mechanism for the drying tower spray gun. Utility Model Content
