Technical Field

The utility model belongs to chemical production exhaust-gas treatment equipment field, concretely relates to papermaking pulping odor treatment device.

Background

Pulping and papermaking are chemical production processes using plant fibers as raw materials, and aim to complete physical and chemical reactions in the processes.
