Technical Field

[0002] As we all know, industrial waste gas refers to a mixture of gases emitted from various industrial production processes, usually containing various solid particles, liquid droplets or gaseous substances, which may contain harmful substances such as sulfur dioxide, nitrogen oxides, volatile organic compounds and heavy metals.
