Chemical process is the process of chemically transforming or processing organic or inorganic raw materials into finished products. Some common chemical processes include weighing, batching, mixing, mixing, drying, burning, calcination, moisturizing, grading, screening and packaging, some dust pollutants will be generated during this process. Traditional chemical plants were once considered the largest source of pollution.

Many substances in chemical production are toxic. If workers are not properly protected during operation, poisoning will occur. Depending on the exposure to poisons, the clinical manifestations of poisoning are also different. When poisons enter the body, they will have different effects on the respiratory system, circulatory system, hematopoietic system, digestive system, and nervous system.

An effective measure to control dust in chemical workshops is a high-efficiency dust removal system. Each dust point uses a suction hood to collect dust, and is connected to a dust collector through an air duct to filter and discharge it. A dust cover must be installed at the discharge point of the bin or silo to create negative pressure at the discharge port and prevent dust from flying. Dust and other production equipment are equipped with closed dust collection systems.
