Environmental Protection
The discharge of flue gas, waste liquid, sewage, etc. seriously pollutes the atmosphere and water resources, and seriously threatens the living environment of human beings. The country regards sustainable development as a national policy, and environmental protection will be the biggest issue in the 21st century. To control air and water pollution, management must be strengthened, and management is based on quantitative control of the amount of pollution.
my country is a country where coal is the main energy source, and there are millions of chimneys in the country that continuously emit flue gas into the atmosphere. Flue gas emission control is an important project to eradicate pollution. Each chimney must be equipped with flue gas analysis instruments and flow meters to form a continuous emission monitoring system. There are many difficulties in the flow rate of flue gas. The difficulty is that the size of the chimney is large and the shape is irregular, the gas composition is variable, the flow velocity range is large, dirt, dust, corrosion, high temperature, no straight pipe section, etc.
