Background
In the process of industrial production, the generation of dust is always a big problem troubling the production, and the dust diffused in a production workshop not only greatly harms the health of production personnel, but also can generate explosion danger due to flammable dust with too high concentration. When the dust is scattered to the outside of the factory, the dust can cause great pollution to the surrounding environment. In addition, some dust can be recycled again but is abandoned due to high collection cost, which causes great waste. When larger particles of dust are treated, the conventional method is to use a filter screen to filter, and when the airflow with dust passes through the airflow channel, the filter screen filters the dust particles in the airflow. The dust treatment mode is simple and easy to implement, but in the dust removal process, the filter screen continuously filters dust particles, so that the dust particles are adhered to the surface of the filter screen, the air permeability of the filter screen is greatly reduced, the air flow speed is reduced, and the dust removal efficiency is reduced. Therefore, the filter screen needs to be frequently disassembled and cleaned, the use is very inconvenient, the dust removal efficiency is greatly reduced, and the dust removal cost is raised. The traditional dust removal mode is characterized in that a dust removal gas pipe is also led into a water tank frequently, liquid in the water tank is used for removing dust in the gas flow, in order to enable the gas flow to flow into deeper water, larger wind power needs to be provided, the energy consumption is high, the gas flow speed is lower, the dust removal efficiency is lower, and the dust removal cost is high.
