【Abstract】 This paper introduces our experiment with and development of a device, known as the rotating stand water film capturing de dusting and de sulphurizing device. The device of ours can help improve the studies de dusting efficiency and speed up the flow and dust concentration. As is known, since the currently used de dusting and de sulphurizing device has the following shortcomings, such as low separating efficiency and low gas emission criterion and serious water laden, which lead to the strong fan vibration, our investigation started with desulfurization device. This new device appends some rotating stands to intensify rotary movements based on the common water film de duster so as to raise the efficiency of de dusting. Attached with a limewater absorber, this device can also be able to desulfurize the gas dust. And concentration of gas dust has no influence on the resistance lose of this device. Thus it can be proved that this device has high efficiency of dust removing and moderate efficiency of desulfurization, the moderate resistance to the loss, less power consumption of the fan and relief of water taking. In addition, the cost to make and run the new device has been considerably reduced as a result of our innovation, which suggests greater potentiality for continuing development of the de dusting and desulfurization technology.更多还原
