In order to suppress dust more effectively, a combination of dry fog dust reduction and chemical dust suppression can be used to suppress dust and stabilize dust, so as to achieve the purpose of longer-lasting and more effective dust reduction. How to design a detection system that can simulate both the effect of dry fog dust reduction and the effect of chemical dust suppression is a problem that technicians in this field need to solve.
