The working principle of the water film desulfurization and dust removal device is that sulfur-containing gas, under the action of the turbocharging turbulence device, rotates and diffuses at high speed to form turbulent mass transfer with the absorbing slurry. The process of mass transfer is to form an emulsion layer between gas and liquid, which not only accelerates chemical absorption and neutralization, but also keeps the liquid film close to neutrality, maintaining a stable mass transfer rate throughout the entire process. Therefore, it is a low resistance desulfurization equipment.

The desulfurization equipment is widely used in the desulfurization and dust removal industry of coal-fired boilers. It can be used for wet dust removal, wet desulfurization, or integrated dust removal, desulfurization, and dust removal. It is not only suitable for dust removal and desulfurization of coal-fired circulating fluidized bed boilers in power plants, but also for wet desulfurization, dust removal, and flue gas purification of coal-fired chain boilers, removing sulfur dioxide and exhaust gas purification. It is applied in the furnace industry to remove hydrogen fluoride and acid waste gas purification equipment for kiln exhaust gas, and for desulfurization of pellet and sintering machine exhaust gas. The purification efficiency of desulfurizer for waste ammonia water can reduce the original flue gas SO2 from 11000mg/m3 to below 120mg/m3, and it is widely used in steel plant pellet flue gas. It is a low resistance wet dust removal and desulfurization equipment and a novel environmentally friendly product for desulfurization equipment.

The working principle is that the dusty gas is introduced from the lower part of the simplified body in a tangential direction, rotates upward, and the dust particles are separated by centrifugal force, thrown towards the inner wall of the cylinder, and adsorbed by the water film layer flowing on the inner wall of the simplified body. It flows with the water to the bottom cone and is discharged through the dust outlet. The formation of the water film layer is achieved by several nozzles arranged at the upper part of the cylinder, which spray water tangentially onto the wall of the device. In this way, a thin water film that rotates downward is always covered on the inner wall of the simplified Chinese, achieving the goal of improving dust removal efficiency. This wet dust collector has a simple structure, low metal consumption, and low water consumption. Its disadvantages are high height, difficult layout, and the presence of water in actual operation.

The technical core is based on the new theory of permeation surface and the strong mass transfer mechanism of multiple turbulent mixing. It belongs to the use of liquid as a separating agent to separate dispersed dust particles, smoke and gas from gas, air or exhaust gas and achieve purification. It has the technology of simultaneous dust removal and desulfurization. Its technical characteristics are: integrated dust removal and desulfurization, low energy consumption, small footprint, simple operation, significant efficiency, low operating costs, no blockage or scaling, stable system operation, low pressure resistance loss, and applicability to various solid sulfur agents (CaO, MgO, NaOH, CaCO3, Na2CO3, NH3 · H2O, industrial waste alkali solution). And achieve zero emissions in the application of coal-fired industrial boilers.
