Technical Field

[0001] The utility model relates to the field of wastewater treatment, in particular to an atomizing device for a wastewater incinerator. Background Art

[0002] Wastewater incinerators use high-temperature combustion to thermally decompose and oxidize organic matter and other pollutants in wastewater, producing harmless substances such as carbon dioxide and water. During the combustion process, the wastewater is atomized into fine droplets, which are fully mixed with combustion-supporting air and then burned in the combustion chamber.

[0003] In the current existing technology, the organic wastewater incinerator is mainly composed of the incinerator body, the air inlet pipe at the top, the air outlet pipe at the bottom and the incinerator. The fan sends the combustion-supporting air into the interior of the furnace body through the air inlet pipe. At the same time, the atomizing device atomizes the organic wastewater, and then the combustion-supporting air blows the atomized organic wastewater into the interior of the furnace body. After that, the burner incinerates the organic wastewater, and decomposes and transforms the organic matter and other pollutants in the wastewater through high-temperature combustion, thereby realizing the harmless treatment of the wastewater.

[0004] However, during use, the atomizing nozzle of the existing atomizing device sprays organic wastewater with poor uniformity, resulting in poor uniformity in the mixing of organic wastewater and combustion air, which in turn affects the burner's incineration of organic wastewater; therefore, a wastewater incinerator atomizing device is proposed to address the above problems.
