Generally, it is necessary to collect odor and waste gas from the equipment that produces odor, and exhaust the air containing odor in the workshop to the outside of the workshop through ventilation pipeline engineering. In addition, due to environmental problems, centralized air purification treatment is needed, which is a huge project. For example: A World Waste Gas Odor Purification Project.
2. Install a negative pressure fan to discharge the odor air in the workshop and exchange fresh air through negative pressure convection.
The specific method is to install negative pressure fans on the walls and windows of the workshop, so as to exhaust the odor air in the workshop outside, artificially create air pressure difference, and force fresh air outside the workshop to supplement the workshop and exchange convection with the odor air in the workshop repeatedly, so as to reduce the amount of odor air in the workshop and increase the oxygen content of the air in the workshop.
For example, Jiafeng, Detong, Lan Haofeng and other negative pressure fans are all good.
