Název v původním jazyce

The flue gas desulphurization at the first stage of the absorber - O-element

Popis výsledku v původním jazyce

Pilot plant wet scrubber is comprised of first stage and second stage. In our experimental setup, O-element is used as a first stage. O-element replaces venturi scrubber that is currently used in practice. O-element is a device used to homogenize the gas-liquid mixture. Upon contact of flue gas and liquid, the hot flue gas is cooled and pollutants are being removed from flue gas. As a second stage a packed column with the structured packing is designed. By a gradual transition from the planar embodiment of the O-element (the O-element 2R) to the spatial arrangement, the four branched O-element - the O-element 4R originated. The design of equipment for the larger flue gas flow rate is necessary, because the waste to energy plants incinerating the municipal and hazardous waste commonly produce flue gas with flowrates in the tens of thousands m3/h. For such flue gas flow rate would the originally designed device O-element 2R be too space-demanding. Spraying a liquid in the four-branched-O element can be performed in two ways. Firstly, it could be managed in the same manner as in two-branched O-element, i.e. through the orifices in the bottom arcs of the equipment, or by spraying of the liquid around the circumference of the inlet pipe. Experiments were performed with the two O-4R elements with liquid spray positioned around the perimeter of the inlet pipe and with the liquid spray through the nozzles in the lower arcs of the equipment. The main observed parameter was the SO2 removal efficiency depending on the L/G ratio. In addition even more important indicator as SO2 removal efficiency was monitored and it was an O-element pressure loss.
