Background technology
At present, the atmosphere pollution that coal-burning power plant causes receives increasing attention, and China is also more and more stricter to the discharge standard of coal-fired power plant's atmosphere pollution, and up-to-date fossil-fuel power plant atmospheric pollutant emission standard (GB13223-2011) is to SO
2emission limit improves comparatively large, and General Requirements is at 100mg/Nm
3within, some areas require 50mg/Nm
3.In " coal electricity energy-saving and emission-reduction upgrading and transformation action plan (2014-2020) ", " eastern region Thermal generation unit SO is then proposed
2concentration of emission reaches discharge of gas turbine limit value substantially " requirement, namely require SO
2emission limit 35mg/Nm
3.This requires that desulfuration efficiency must reach 98%, even more than 99% and could meet emission request, and now, traditional single tower single cycle Wet Flue Gas Desulfurization Technique has been difficult to realize this target.
Single tower Two-way Cycle Wet Flue Gas Desulfurization Technology is proposed by German Knoll Inc. the earliest, flue gas point two-stage washing in its absorption tower: bottom mainly cools, pre-wash flue gas and calcium sulfite oxidation become gypsum, and the pH value of lower closed circuit is 4.0-5.0; Top is then mainly risen and is absorbed SO
2effect, the pH value in cocycle loop is 5.5-6.5.Flue gas, behind cooling zone, enters the absorption circuit on top by liquid collector deflector.This technology has good SO
2load fluctuation buffer capacity, is particularly suitable for the means of flue gas desulfurization of power plant of high sulfur content, high desulfurization efficiency.
In single tower Two-way Cycle Wet Flue Gas Desulfurization Technology, liquid collector is its key core device, and its effect is separated by the upper and lower loop slurry with different pH value, to ensure that two closed circuits independently control.
At present, those skilled in the relevant art are mainly cone bucket shape formula for the research of liquid collector, as: US Patent No. 4250152A, US4322392A and US7294322B2 and Chinese patent CN203494395U the technical scheme that provides be the liquid collector of cone bucket shape formula, US Patent No. 5451250A is perforate on the liquid collector of cone bucket shape formula.Chinese patent CN102764583A discloses a kind of liquid collector of swash plate form, slurry stream can be made to side so that slurries are discharged.Above-mentioned patent document represents in the art for the more advanced achievement in research of liquid collector, but, all there is following drawback in above-mentioned liquid collector: flue gas flows through these liquid collectors and enters in the process of cocycle by lower circulation, often cause larger drag losses, what in cocycle loop, flue gas flow rate distribution also can become is uneven, make gas-liquid contact in tower insufficient, mass transfer ability declines, and finally affects desulfuration efficiency.
