Abstract
The invention relates to an efficient gas-liquid flow equilibrating device of a square-box type desulfurizing tower. The efficient gas-liquid flow equilibrating device comprises a plurality of gas-liquid flow equilibrating plate modules which are horizontally arranged along the cross section of the desulfurizing tower and are connected into a whole, wherein each gas-liquid flow equilibrating plate module comprises a plurality of steel plates longitudinally arranged in parallel, the steel plates are arranged equidistantly, and each steel plate is a straight plate; triangular dustproof plates are arranged in the connection positions of the gas-liquid flow equilibrating plate modules. In the efficient gas-liquid flow equilibrating device, gas flow performs rotary disturbance, gas and liquids are more sufficiently contacted, the desulfurizing reaction area is increased, meanwhile, smoke and gypsum slurry in the gas and liquids are removed, and the dust removal purpose is achieved.
Description
technical field [0001] The invention relates to a high-efficiency gas-liquid equalization device for a square box type desulfurization tower. Background technique [0002] With the continuous development of China's economy, the demand for electricity continues to increase, and the smog continues to affect it. Controlling PM2.5 is on the agenda. Local governments and power companies have put forward the construction or renovation requirements of "ultra-low emissions", "near-zero emissions", and "meet gas turbine emission standards". "Ultra-low emission" technology scientifically guides the sustainable development of the thermal power industry with ultra-clean emissions. [0003] The Development and Reform Commission issued the "Coal Power Energy Conservation and Emission Reduction Upgrading and Transformation Action Plan (2014-2020)" to strictly control the emission of air pollutants. Newly built coal-fired power generating units (including units under construction and proj...
