Profile of Dual-Fluid Nozzles
Released：2024-11-26 Form：original
Dual-fluid nozzles are based on the principle of internal mixing, ensuring efficient atomization. In these dual-fluid nozzles, water is injected axially. The liquid is then split by a cone into a thin liquid film. In the mixing chamber, the liquid film is broken down into very fine droplets by atomizing air. The different flow velocities of gas and liquid within the nozzle create pressure waves that further break down the liquid into extremely fine droplets, achieving a refined and uniform distribution of the liquid. "Dual-fluid nozzles are particularly suitable for the atomization and injection of media such as urea, ammonia water, waste liquids, and sewage. The nozzle is equipped with a silicon carbide protective sleeve, with the nozzle placed inside the sleeve to protect it from wear caused by high-temperature, high-dust, and high-velocity flue gases.
Direct flue gas spray evaporation technology involves atomizing desulfurized wastewater through a dual-fluid nozzle and then spraying it into the dust collector inlet flue, using the residual heat of the flue gas to cause instantaneous evaporation. The crystalline salts produced after the wastewater evaporation adhere to the fly ash in the flue gas, are captured and collected in the dust removal system, and are discharged along with the ash. The water vapor, after evaporation, enters the desulfurization tower with the cleaned flue gas and condenses into fresh water for recycling in the absorption tower. When the atomized particles mix with high-temperature flue gas, they evaporate rapidly, carrying away heat. At the same time, some of the water vapor combines with the dust in the flue gas, achieving the purpose of dust conditioning.
