Description
Technical Field
The invention belongs to the technical field of environment-friendly equipment, and particularly relates to a bag type dust removal and collection device.
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 dust particles are treated, the traditional mode is that a filter screen is adopted for filtering, and when an air flow with dust passes through an air flow channel, the filter screen filters the dust particles in the air flow. The dust treatment mode is simple and easy to implement, but in the dust removal process, the dust particles are continuously filtered by the filter screen and are adhered to the surface of the filter screen, so that the air permeability of the filter screen is greatly reduced, the air flow speed is reduced, and the dust removal efficiency is reduced. When the filter screen is used for a long time, the filter screen can even be completely blocked, and cannot play a role in filtering, so that the filter screen needs to be frequently replaced and cleaned in the production process, the dust removal efficiency is greatly reduced, and the dust removal cost is raised.
