A lot of smoke and dust will be generated in the process production, which is extremely harmful to the environment and human life and health. It can be seen that the importance of installing dust collectors.
Since the 20th century, the world industry has developed rapidly, and the industrialization process of various countries in the world has accelerated. In the 21st century, energy conservation and environmental protection have become the consensus of the whole society. With the enhancement of environmental protection awareness, various new environmental protection technologies and equipment are constantly emerging and gradually being improved. In the next few years, we can expect to closely combine industrial dust reduction and energy conservation. The application of industrial dust control technology can simplify the process, reduce production energy consumption, and improve the utilization rate of secondary energy; while ensuring the dust removal effect, try to reduce the process air flow, reduce system resistance, and thus reduce its own energy consumption. With the gradual improvement of my country's atmospheric pollution emission standards, especially the increasing requirements for the control of fine particles, the research and development of new and efficient dust removal equipment has also come into being.
Soot is a solid waste generated by the mixture of fuel and fuel, and its main components are different types of particulate matter. Soot exists in the form of solid and liquid. Solids are flue gas, carbon black, dust, etc.; liquids are water droplets, sulfuric acid mist, etc. The dust discharged from the chimney can be divided into two categories: one is dust suppressant, and the other is suspended dust agent. Most of it is carbon that has not been fully burned, so what we see is black smoke. Dust is a very small particle with a diameter of less than 10μm, which is smaller than bacteria. It can be suspended in the air as an aerosol and suspended in the air for a long time at a distance of several thousand to tens of kilometers, causing air pollution. Among them, particles of 0.5~5μm are the most harmful to human health. This is because it can directly reach the lungs and be stored in the lungs. It may also enter the blood and then be transported to various parts of the body, causing damage to the body. In addition, it is hygroscopic and easily absorbs water in the air. A very strong condensation nucleus will be formed on the surface, which can inhale harmful gases, metal dust, highly carcinogenic benzopyrene and other substances discharged from high-temperature smelting into the deep respiratory system through breathing, thereby causing great harm to the human body. Among these pollutants, particles of 0.5-5μm are the most harmful. This is because it can reach the lungs directly and be stored in the lungs, or it can spread to all parts of the body through the blood, thus causing harm to the human body. In addition, due to its excellent water absorption, it is very easy to absorb in the atmosphere, and a strong condensation nucleus will be formed on its surface, which can carry harmful gases, metal dust, highly carcinogenic benzophenone and other substances produced during high-temperature smelting through the respiratory tract into the deeper respiratory tract, causing great harm to humans. Floating dust also has the function of adsorbing pathogenic microorganisms. When the dust concentration is high, the number of various microorganisms in the atmosphere will also increase, leading to secondary infection of chronic diseases, thereby causing a decrease in the body's resistance and immune function.
The above discusses the importance of installing dust collectors from the two aspects of environment and health. It can be seen that dust collectors are indispensable and are constantly developing.
