As a thermal energy device that uses biomass pellets as fuel and heats air or gas through the heat energy generated by combustion, biomass pellet hot air furnace plays an important role in modern industrial and agricultural production. However, the dust emission problem during its operation has always been the focus of attention in the field of environmental protection. This article will explore how to solve the dust emission problem in the operation of biomass pellet hot air furnace.First of all, the selection and treatment of fuel is the key. As a fuel, the quality and treatment method of biomass pellets directly affect the combustion efficiency and dust emission. Therefore, high-quality, low-ash biomass pellets should be selected, and sufficient pretreatment such as crushing and screening should be carried out before combustion to reduce dust generation.Secondly, efficient dust removal equipment is a guarantee. Bag dust collector has become the first choice for solving the dust emission problem of biomass pellet hot air furnace with its high dust removal efficiency and mature technology. Bag dust collector captures fine dust particles in the flue gas through the filtering effect of the filter bag. To ensure dust removal efficiency, the filter bag material must be resistant to high temperature and corrosion, and the filter bag filtration wind speed should be controlled within a reasonable range. In addition, the bag filter is also equipped with a pulse cleaning system, which can regularly remove dust accumulation on the surface of the filter bag to prevent blockage and wear.Furthermore, flue gas pretreatment technology is also crucial. Before the flue gas enters the bag filter, pretreatment equipment such as cyclone dust collectors can be used to separate large particles of dust by using the centrifugal force generated by the rotation of the flue gas itself, thereby initially reducing the dust concentration in the flue gas and reducing the burden on the bag filter.In addition, strengthening operation management and maintenance should not be ignored. Regularly cleaning and maintaining the biomass pellet hot air furnace and its dust removal equipment, and timely cleaning of dust and debris can effectively avoid impurity pollution caused by dust accumulation in the equipment, while improving the equipment's operating efficiency and dust removal effect. At the same time, a sound operation management system should be established to ensure the stable operation of the equipment and meet emission standards.In summary, solving the dust emission problem in the operation of biomass pellet hot air furnaces requires multiple approaches, including selecting high-quality fuels, using efficient dust removal equipment, implementing flue gas pretreatment technology, and strengthening operation management and maintenance. Through the implementation of these measures, the dust emission of biomass pellet hot air furnaces can be effectively reduced, protecting the environment and human health.
