Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of absorption towers, in particular to a gas distributor structure at an air inlet of an absorption tower. Background Art
[0002] Absorption tower is an important equipment widely used in chemical industry, environmental protection and other industries. It is mainly used for gas purification and material absorption. By introducing absorption liquid into the tower, the gas and liquid are fully in contact, and the physical or chemical reaction between the two is used to remove specific gas components or pollutants. In the absorption tower, the uniform distribution of gas is crucial to improving absorption efficiency and ensuring treatment effect. Therefore, as an important component of the absorption tower, the design and performance of the gas distributor directly affect the efficiency and effect of the entire absorption process.
[0003] A double-row blade distributor is a gas distribution device widely used in absorption towers. It is usually composed of two rows of parallel blades with relatively large gaps between the blades, aiming to ensure that the gas can pass smoothly and guide the airflow to different areas of the absorption tower. However, the existing double-row blade distributors still have obvious inadequacies in practical applications. Specifically, since the existing double-row blade structure is relatively simple and usually only adopts a straight blade design, it is difficult to ensure that the airflow can be completely evenly distributed when passing through the distributor, and it is easy to have the phenomenon of too dense or too thin airflow in local areas. At the same time, when the flat edges of the existing blades work at a higher airflow speed, obvious aerodynamic noise is easily generated between the airflow and the blades. The vortex and separation phenomenon generated when the airflow passes through the distributor blades aggravates the noise problem and affects the working environment of the workers. Therefore, it is particularly important to improve the existing gas distributor structure and design a new absorption tower inlet gas distributor structure to solve the above-mentioned technical defects and improve the practicality of the overall gas distributor structure.
