Fly ash itself has no taste, and its main components are elements such as silicon, aluminum, and iron, similar to the residue of coal burning. Therefore, fly ash itself does not have the effect of removing odors. However, in the process of collection, storage and utilization of fly ash, fly ash may emit some bad odors due to various reasons, affecting the surrounding environment and people's health. In order to absorb the smell of fly ash, the following measures can be taken:
1. Strengthen ventilation.
The place of collection, storage and utilization of fly ash should be well ventilated to allow air circulation and reduce the accumulation of bad odors. Ventilation can be achieved by natural ventilation or mechanical ventilation. For closed or semi-enclosed places, such as fly ash dumps, storage depots, etc., ventilation equipment such as exhaust fans can be installed to ventilate regularly.
2. Take deodorization measures.
Different deodorization measures can be taken for the different odors that fly ash may emit. For example, adsorbents such as activated carbon and oxidants can be used to adsorb odors;Microbial deodorants can also be used to break down odorous substances;It can also mask the odor by spraying perfumes, essences, etc. These deodorization measures can be used according to the actual situation or a combination of them.
3. Control the sulfur content of fly ash.
The sulfur element in fly ash is one of the main causes of undesirable odors. Therefore, controlling the sulfur content of fly ash can effectively reduce the generation of undesirable odors. The sulfur content in fly ash can be reduced by optimizing the combustion process and parameters of coal;It is also possible to add desulfurizers to coal to reduce the sulfur content.
Fourth, the rational use of fly ash.
The rational use of fly ash can reduce the generation of undesirable odors. For example, when fly ash is used to make building materials such as cement and concrete, appropriate mix ratios and process parameters can be used to reduce the generation of undesirable odorsWhen fly ash is used to improve the soil, the application rate and application method can be controlled to avoid excessive use that leads to excessive alkalinization of the soil and undesirable odors.
5. Strengthen management.
Strengthening the management of fly ash collection, storage and utilization can effectively reduce the generation and spread of undesirable odors. For example, establish a sound fly ash management system and operating procedures, and strengthen equipment maintenance and maintenance;Regularly clean and disinfect the fly ash utilization site;Strengthen the management and supervision of fly ash transport vehicles.
To sum up, the absorption of fly ash taste needs to start from ventilation, deodorization measures, sulfur content control, rational utilization and strengthened management. In practical application, the appropriate method can be selected according to the actual situation or a combination of methods can be used to absorb the taste of fly ash and improve the surrounding environment and people's health. At the same time, it is also necessary to strengthen technological innovation and research and development, and explore more effective methods and technologies to absorb the taste of fly ash.
