The evaluation of the 2019 Fujian Science and Technology Award has been completed. The project 'Key Technologies and Industrialization of Cooperative Governance of Non-point Source VOCs and Particulates in Workshops' participated by Aolan won the second prize of the 2019 Fujian Science Progress Award.

The non-point source VOCS and particulate matter in the workshop have many divergence points, complex components, and difficult collection. The subject and task of this research are mainly to use a wet curtain with photocatalytic decomposition ability after a special process, and collaborative filtering, UV lamps The technology treats the harmful and particulate matter in the workshop. After the treatment, the air that meets the emission standards is harmlessly discharged outdoors. For the air cooling treatment of the supplementary air, in order to achieve the most energy-saving purpose, the wet curtain direct evaporative cooling technology is adopted in the project. The workshop delivers cool clean air.

This project is another achievement of the Aolan research team applying evaporative cooling technology to solve actual production problems.
