Bag filter is a commonly used dust removal equipment, which is mainly used to remove dust and particulate matter in flue gas generated in industrial production processes. In biomass boilers, baghouses also play an important role.
Biomass boiler is a kind of boiler that uses biomass as fuel, which has the advantages of environmental protection, energy saving, and renewable. However, biomass fuels will produce a large amount of dust and flue gas during combustion, and if these dust and flue gas are directly discharged without treatment, they will cause serious pollution to the environment. Therefore, the bag filter plays an indispensable role in the biomass boiler.
The working principle of the bag filter is to use the filter cloth to separate the dust and flue gas, through the filtration effect of the filter cloth, the particles are left on the filter cloth, and the clean flue gas is discharged through the filter cloth. When the dust on the filter cloth reaches a certain thickness, it is necessary to clean the ash to prevent the filter cloth from clogging and affecting the dust removal effect.
In a biomass boiler, there are several factors that need to be considered in the design of a baghouse. First of all, biomass fuel has a high combustion temperature, so the baghouse needs to be able to withstand the impact of high-temperature flue gases. Secondly, biomass fuel contains a large amount of ash and impurities, which will cause wear and clogging of the bag filter, so it is necessary to choose a filter cloth with high wear resistance and high filtration efficiency. In addition, the flue gas of the biomass boiler contains a large amount of water vapor and acid gas, which will cause corrosion and damage to the bag filter, so corresponding anti-corrosion measures need to be taken.
When applying a bag filter in a biomass boiler, the following points also need to be noted. First of all, the bag filter needs to be inspected and maintained regularly to ensure its proper operation and extended service life. Secondly, the temperature and flow of the flue gas need to be reasonably controlled to avoid excessive load on the bag filter. In addition, the filter cloth needs to be cleaned and replaced regularly to ensure its filtration efficiency and dust removal effect.
In conclusion, the bag filter plays an important role in the biomass boiler. Through reasonable selection, design and maintenance, it can effectively remove particulate matter in the flue gas and protect the environment and human health. At the same time, with the continuous improvement of environmental protection requirements and the continuous development of technology, the application prospect of bag filter in the future will be broader.
