The Dust Removal Work Is Urgent

Due to the limitations of China's energy endowment conditions, coal has always been the main primary energy in China, from 1995 to 2011, coal accounted for an average of about 70% of China's primary energy consumption. This coal-based energy structure determines that carbon dioxide, sulfur dioxide, soot and dust generated by coal combustion are important factors causing air pollution in China. At the same time, the rapid development of metallurgy, cement, waste incineration and other industries has brought dust and dust emissions, further increasing the pressure on environmental protection. According to data from the Ministry of Environmental Protection, in 2010, China's soot emissions were 8.291 million tons, of which 6.032 million tons were industrial soot emissions. Soot and dust are mainly composed of particulate matter and are produced in large quantities in the production of many industrial sectors such as mining, metallurgy, machinery, building materials, light industry, and electric power. For the environment, the dust discharged into the atmosphere for a long time will reduce the atmospheric visibility, can cause soot pollution; For the human body, inhalable dust can lead to progressive pulmonary fibrosis, cause lung function decline, dust contains trace heavy metals, radioactive elements can also cause senile dementia, leukemia and other fatal diseases. In order to mitigate these hazards, dust collectors, as the main means and equipment for atmospheric dust removal, have been widely used by various industrial sectors. Under the action of all kinds of dust collectors, the removal amount of industrial dust and dust in China has steadily increased.
