Organic fertilizer, as an important "nutrient" for green agriculture, is often hampered by dust issues during its production process. Dust not only pollutes the production environment and harms worker health, but also can lead to raw material waste and safety hazards. Therefore, implementing dust reduction measures throughout the entire organic fertilizer production process is crucial.
In the raw material pretreatment stage, dust mainly originates from the crushing and conveying of materials such as straw and livestock manure. To address this, companies can install enclosed dust covers on crushers, conveyor belts, and other equipment, along with bag filters to collect and filter suspended dust through negative pressure adsorption. Simultaneously, moderately atomizing and humidifying dry straw-like raw materials to control the material's moisture content within a reasonable range reduces the probability of dust rising without affecting subsequent fermentation. Some companies also install windbreak and dust suppression nets in raw material storage areas to reduce dust spread during open-air storage.
Dust in the fermentation and composting stage mainly comes from the turning and composting operations. Traditional open-style turning and turning processes easily lead to dust escape. A closed fermentation workshop can be used instead, with a spray system installed above the turning machine to absorb dust particles using water mist. Furthermore, using a trough-type aerobic fermentation process, combined with a central dust collection system within the workshop, can centrally treat the dust generated during turning and turning, achieving a dust-free fermentation environment.
In the finished product processing and packaging stages, crushing, screening, and packaging are high-dust-generating processes. Enterprises can install cyclone dust collectors at the crusher outlet to separate large dust particles first, followed by fine dust treated by cyclone dust collectors. The packaging process should utilize automated sealing packaging equipment to reduce dust leakage from manual operation. Simultaneously, local dust collection devices should be installed in the packaging area to ensure no dust spillage, thus building a solid defense for a dust-free final stage of the entire organic fertilizer production line.
Besides hardware upgrades, management measures are also indispensable. Regular maintenance and calibration of dust removal equipment ensures its operational efficiency; professional dust-proof protective equipment is provided to workers, and dust protection training is conducted; a dust monitoring mechanism is established to monitor workshop dust concentration in real time and adjust dust reduction plans accordingly.
Through comprehensive technological upgrades and refined management, organic fertilizer production can both adhere to environmental protection standards and ensure production safety, laying a solid foundation for the industry's green transformation.
