(1) meet the requirements of complex chemical corrosion conditions of environment: chimney complex chemical environment within the high acid content of the flue gas, the condensate formed on the surface of the lining, for most of the construction materials are highly aggressive , so the lining material is required to have anti-acid corrosion; (2) the temperature requirements: flue gas temperature changes, wet flue gas desulfurization temperature between 40 ℃ ~ 80 ℃, the desulfurization system overhaul or not running The unit operating conditions, cyclone desulfurization tower, the chimney flue gas temperature between 130 ℃ ~ 150 ℃, it requires changes in temperature capability with anti-lined, cracking and durable frequent changes in temperature environment; (2) highly corrosive typical limestone (lime) - gypsum desulfurization, pH value of the slurry is generally bottoms 5-6, after adding the desulfurization agent up to 6 to 8.5 pH value (pH value of the circulating pump slurry and desulfurization tower Join points desulfurizer operating conditions and related); Cl- can be enriched over 80000mg / L, under the conditions of low pH, it will have a strong resistance. (3) cavitation of desulfurization systems, circulation pumping slurry often contains a certain amount of gas. In fact, centrifugal slurry pump delivery cycle for gas solid-liquid multiphase flow, affecting relatively solid performance of the pump is continuous and uniform, and the impact of the gas pump than the relatively solid phase complex and difficult to predict. When the liquid is pumped contained gas pump flow, head, efficiency has declined, the greater the gas content, efficiency decreases faster. With the increase of the gas content of the pump from the extra noise and vibration, may lead to the shaft, bearings and seal damage. Pump suction port and leaves the back etc. gather gas flow resistance will lead to increased resistance or drying, spray desulfurization tower, and then make the condition worse, cavitation must increase, small gas density, specific volume, desulfurization tower, compressibility large, rheology strong, small centrifugal force caused by the conversion of energy performance difference is the main reason for the deterioration of the pump operating conditions. Tests showed that when liquid gas (volume ratio) of around 3%, the pump performance drop will occur only when the inlet gas of 20% to 30%, the pump is completely stop. Centrifugal allow gas content (by volume) of less than 5 percent limit.
