Description

Technical field [0001] A flue gas dust removal and purification device belongs to the field of flue gas dust removal and purification. It is an efficient, energy-saving and environmentally friendly flue gas dust removal and purification device. Background technique [0002] With the rapid economic development, my country’s comprehensive national strength has been increasing day by day. Pillar industries such as chemical industry, energy, metallurgy, and electric power have made great contributions to my country’s national economy. However, the exhaust gas produced by heavy industry has caused serious damage to my country’s atmospheric environment. Pollution. As a country that uses coal as its main energy source, it is estimated based on historical data that the air pollutants produced during combustion account for about 70% of the total air pollutants, and coal emissions account for 96% of the total emissions from combustion. Hazardous substances produced by burning coal account...

Problems solved by technology

The bag-type dust collector does have a good effect on the purification of flue gas, but the bag-type dust collector itself also has certain shortcomings: 1. The quality of the bag filter material is not good enough, and the service life of the bag is short; 2. Secondary pollution of the bag-type dust collector Serious, directly endangering the health of operating workers; 3. It is difficult to detect damaged cloth bags, and production must be stopped during replacement and maintenance, which affects the normal production of the enterprise
