During dust operation, dust pollution is serious, and certain measures should be taken to prevent dust and reduce dust.

The

1. process measures

(1) Avoiding the use of hazardous raw materials or production processes is the fundamental way to eliminate and reduce dust hazards. The

(2) Reform process equipment and process operation methods and adopt new technologies. The

(3) The layout of process equipment and production process shall ensure that the main working places and sections with many operators are located in the workshop where the ventilation is good and the air is relatively clean, and the sections with serious dust pollution shall be placed at the downwind side of the perennial dominant wind direction. The

2. sealing measures

The closed dust source makes the production process pipelined, mechanized and automated. It is an effective measure to prevent dust from escaping. It can also greatly improve the working conditions, reduce the labor intensity, avoid direct contact between dust and human body, and achieve the purpose of dust prevention. The

The

3. wet operation

This is a simple, economical and effective dust prevention measure, which should be considered first when production and process conditions permit. For example, changing the dry crushing, grinding, screening and mixing of materials to wet operation, adding water to the materials during the loading, unloading and transfer of materials can reduce the generation and flying of dust, and washing the ground, walls, equipment covers and building components with water in the workshop can effectively prevent secondary dust
