The flour mill explosion incident serves as a warning to us that dust collectors in flour mills are extremely necessary, mainly reflected in the following aspects:
1. Reduce dust concentration:
-Prevent explosion: There is a large amount of flour dust suspended in the air of flour mills and other places. When the dust concentration reaches a certain range, it will trigger an explosion when it encounters a fire source. The pulverizer dust collector can collect and filter dust in the air in a timely manner, reduce the concentration of dust in the working environment, and keep it within a safe range, thereby effectively preventing explosion accidents. For example, under normal circumstances, the dust concentration in a powder factory ranges from a few grams to tens of grams per cubic meter. If a dust collector is not used, the dust will continue to accumulate during the production process, and the concentration may rapidly increase, reaching the explosive limit.
-Compliance with safety standards: In order to ensure production safety, relevant industry standards and regulations have strict restrictions on dust concentration. Installing crushers and dust collectors is a necessary measure for flour mills and other flour related enterprises to meet safety standards and operate legally and compliantly.
2. Eliminate the hidden danger of ignition sources:
-Avoid static sparks: During dust collection and processing, static electricity is easily generated due to friction between dust and equipment, pipelines, and filter bags. If static electricity cannot be removed in time, it may accumulate to a certain extent and generate static sparks, becoming the ignition source for dust explosions. The dust collector of the crusher can effectively eliminate static electricity and avoid the generation of static sparks by adopting anti-static filter bags and setting grounding devices.
-Preventing mechanical sparks: Dust collectors can collect and process metal debris, friction sparks, etc. generated during the operation of production equipment to prevent these mechanical sparks from coming into contact with dust and causing explosions. For example, near the crushing and conveying equipment in a flour mill, it is easy to produce foreign objects such as metal shavings. If not cleaned up in a timely manner, it will increase the risk of explosion. The pulverizer dust collector can promptly remove these potential ignition sources.
3. Ensuring the health of personnel:
-Reduce dust inhalation: Workers who are exposed to high concentrations of dust for a long time are prone to inhaling large amounts of dust, which can cause occupational diseases such as pneumoconiosis. Industrial dust collectors can effectively reduce the dust content in the air, provide a relatively clean working environment for workers, and reduce the harm of dust to human health.
-Improving the working environment: A good working environment is not only beneficial for the physical health of workers, but also enhances work efficiency and production quality. The use of dust collectors can reduce the diffusion of dust in the workshop, maintain fresh air, and improve the comfort of the working environment.
4. Reduce equipment damage:
-Prevent dust accumulation: If dust accumulates in large quantities on the surfaces of production equipment, pipelines, electrical equipment, etc., it will affect the heat dissipation performance of the equipment, cause overheating, and even trigger fires. Industrial dust collectors can promptly remove these dust particles, avoiding equipment damage caused by dust accumulation.
-Extending equipment lifespan: Reducing the wear and corrosion of equipment caused by dust can prolong the service life of equipment and reduce the maintenance costs of enterprises. For example, in a flour mill, dust can cause wear on components such as bearings and seals of conveying equipment. Using a dust collector can reduce this wear and extend the maintenance cycle and service life of the equipment.
