Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lye spray towers, in particular to a lye spray tower for purifying acidic gases. Background Technique
[0002] A lye spray tower is a common gas purification device in industrial applications, mainly used to remove or neutralize acidic gases such as sulfur dioxide (SO2), nitrogen oxides (NOx), hydrogen chloride (HCl), etc. With the acceleration of the industrialization process, the problem of air pollution has become increasingly serious, especially the emission of acidic gases has a serious impact on the environment and human health. Therefore, developing effective acidic gas purification technologies has become an important topic in environmental protection. The lye spray tower utilizes the principle of acid-base neutralization reaction. By spraying an alkaline solution (such as sodium hydroxide, calcium hydroxide, etc.) to contact with acidic gases, gas purification is achieved. For example, sulfur dioxide reacts with sodium hydroxide to form sodium sulfate and water. Early gas purification technologies were relatively simple and inefficient. With the development of technology, modern lye spray towers have adopted more efficient spray systems, more optimized structural designs, and automated control systems, improving the purification efficiency and operation convenience. A typical lye spray tower system includes links such as gas introduction, lye spraying, gas-liquid contact, gas separation, and discharge. The gas fully contacts the sprayed lye during the rising process to achieve the neutralization of acidic gases.
[0003] In actual use, without effective liquid dispersion, the spray tower may not be able to handle the designed maximum gas flow rate, limiting its processing capacity. The accumulation of liquid in certain areas may cause corrosion or blockage inside the equipment, which will increase the equipment maintenance cost and downtime. Uneven liquid distribution may cause some components to withstand uneven corrosion, thereby shortening the service life of the equipment. To achieve the same purification effect, it may be necessary to increase the operating parameters of the spray tower, such as increasing the working pressure of the nozzles or raising the rotational speed of the motor, which will increase energy consumption. The uneven distribution of liquid in the tank may cause increased corrosion in certain areas, increasing the risk of equipment leakage and posing a safety hazard. The absence of or poor effect of the flapping blocks may cause fluctuations in the operation of the spray tower, affecting the stability of operation. Content of the Utility Model
