Background

In order to better protect the atmospheric environment and the ecological environment of the area and reduce the cost of enterprises, the existing coal-fired boiler needs to be effectively improved and reformed, so that the fuel can be changed from coal powder to biomass powder.

The biomass powder used as the fuel is generally selected from waste materials such as wood sanding powder in the wood finishing process, a small amount of impurities are contained in the materials during recycling and processing, if the impurities enter an impeller powder supply machine to cause blockage and enter a combustor to cause blockage of a combustor nozzle, a filter device is added in a fuel conveying pipeline before the biomass powder is put into a bin, and the biomass powder is subjected to rescreening. Because the fluidity of biomass powder is worse than that of coal powder, when the biomass powder passes through the existing filtering device, the filtering device is easy to be blocked, and the use of the boiler is affected.

Therefore, it is necessary to design a device which can filter the biomass powder before being put into a warehouse and can ensure that the biomass powder does not cause blockage to a filter device.
