In accordance with the client’s requirements, the design includes a dedusting system for municipal waste cutting, crushing and chopping municipal waste, a filter bag dust collector, and a carbon filter at the outlet. The carbon filter is intended as a temporary solution to accommodate a flow rate of 20,000m3/h and will not be part of the measurement or monitoring process.

The client provided detailed descriptions and requirements regarding the dust removal system. In addition to addressing odor and dust issues, it was crucial to meet the regulations set by the Environmental Agency. The existing permit demanded air emissions to adhere to the following criteria: total dust (10 mg/m3), organic matter expressed as total carbon (TOC, 20 mg/m3), and inorganic compounds of chlorine from Group III hazardous substances (HCl, 20 mg/m3) at a mass flow rate of 100g/h. Furthermore, the entire powder had a maximum mass flow rate of 1 kg/h, and the maximum estimated value of diffuse emission of total dust could not exceed 100g/h.
Considering the best available techniques (BAT), stricter requirements were taken into account, particularly for dust (2-5 mg/m3). DECENT MACHINERY design aims to meet these stricter standards.
To accommodate the client’s needs, intend to retain the existing fan. Given that dust could contaminate a room with a volume of 4325m3, including 0-10mm airborne particles in the event of a malfunctioning fan, it is recommended to incorporate a pre-filter (such as a bag filter) to capture removed materials for storage.
The overall process entails cutting and grinding raw mixed municipal waste, utilizing an excavator for transshipment and filling into the trough of the first coarse mill. Subsequently, the first milled waste passes through a conveyor to the separator for coveings and hard particles, which then proceeds to the next two secondary mills for further size reduction. The final fine fraction is transported via conveyor belt with two overflow points to an adjacent room, forming a pile of final fractions. Excavators are employed to transport the final fractions to a covered depot, where they undergo partial drying before being sent for incineration, either domestically or internationally.
The primary objective is to ensure the removal of dust from the dumping sites, conveyors of the secondary municipal waste mills, and the final fraction transporters, while maintaining emissions compliance mandated by the law. Carbon filters should be implemented within the dedusting system to satisfy the required flow rate. However, these measurements need not be operational; their installation is solely for demonstration purposes.
The facility has three main sources of dust.
