A solid waste treatment company in Kunming, Yunnan, has long faced dust pollution issues in its powder transportation process. Based on the actual working conditions of this enterprise, our company designed and implemented a solid waste powder dust-proof transportation project. By combining a sealed conveying system with negative pressure dust removal technology, we achieved a dust-free transfer of powder from the storage silo to the terminal equipment. After the project was put into operation, the on-site environment improved significantly, and dust emission concentrations remained below national standards.

Customer pain points

In the original conveying process, the customer used open belts or simple pipelines for powder transfer, resulting in large amounts of fine powder leaking at the discharge point, transfer point, and pipeline interface. Dust fills the workshop, workers must wear dust masks during work, and the equipment surface is covered with severe dust, which not only increases maintenance costs but also frequently causes equipment failures due to dust accumulation. At the same time, the company faces regulatory pressure from environmental protection authorities and has been repeatedly required to rectify dust issues, urgently needing a solution to control dust from the source.

Product advantages

To address customer pain points, our company offers the following comprehensive solutions:

• Fully sealed conveyor link: Uses a sealed system combining pneumatic conveying and pipe chain conveying, with sealing gaskets and quick-install clamps at all joints to eliminate leakage points.
• Negative pressure dust removal linkage: Pulse reverse blow dust collectors are installed at the discharge point and on top of the silo to start and stop in sync with the conveying system, collecting and reusing esperious dust to achieve low emissions.
• Intelligent control: Equipped with a PLC automatic control system to monitor pipeline pressure, material level, and dust collector operating status in real time. Process parameters can be automatically adjusted during abnormalities, supporting continuous and stable material feeding.
• Modular design: The equipment uses prefabricated modules for rapid on-site assembly, reducing downtime and facilitating later expansion or relocation.

Application Effects

After the project was put into operation, the dust concentration on site dropped from the original 12 mg/m³ to below 2 mg/m³, improving workshop visibility and fundamentally improving the working environment for workers. Equipment power consumption is about 18% lower than traditional air conveyor systems, and maintenance intervals are extended to over six months. This case has become a demonstration project for dust prevention and conveying of powders in the local solid waste industry, earning high recognition from environmental protection departments and customers.
