2, good cooling effect.Because turbulent flow parts of this device and diversion component combination make flue gas produce the high-efficiency turbulent flow state; top is sprayed the liquid that gets off breaks up and becomes very fine particle; flue-gas temperature reduces rapidly; it is more thorough on the one hand reaction to be carried out; anti-corrosion material is protected in the absorption tower; can save the cooling installation before the absorption tower on the other hand, reduce plant investment.
3, energy consumption is low.The absorption tower section arranges that one deck revolves the remittance coupling device, flue gas produces the turbulent flow space that the gas-liquid rotation is seethed through this device, it is long-pending to improve the gas-liquid contact surface, therefore the required slurries amount of absorption reaction reduces, liquid-gas ratio is little, and the slurries internal circulating load is little, and system's power consumption is low, can regulate circulating pump according to parameters such as payload, contents of sulfur dioxide during operation and open the platform number, reduce desulphurization system operating cost.
4, security of operation, operating flexibility is big.This device has improved heat and mass speed, and it is wideer to make device adapt to the scope of different operating modes, different unit load and different material quality, has improved operation elasticity, makes system's operation more safe and efficient stable.
5, simple in structure.No rotating machinery in the whole device revolves the remittance coupling device and once finishes at the installation initial stage, and long service life need not maintenance repair.
6, system's operational reliability height.Owing to increase in the absorption tower and revolve the remittance coupling device, be used to carry the circulating pump of the liquid platform number that puts into operation to mediate according to operating mode, pollutant load, avoided the round-the-clock running of circulating pump, when prolonging equipment life, for overhaul of the equipments provides powerful guarantee, make desulphurization system operation operational percentage height, system's operation safety and reliability.
