2. after the shower nozzle is stopped up by marine growth, cause the seawater skewness, local filler has the danger of being melted by flue gas, carry out the labor cleaning after stopping up, have because damper is not closed completely, cause the danger of maintainer's smoke poisoning, the problem of the impact person and device security.
3. need after shower stops up the desulfurization stoppage in transit is checked processing, can not guarantee the continuous operation of desulphurization system, affect the problem of equipment dependability.
4. because the part spray apertures is stopped up, have to increase seawater flow, cause desulphurization system to depart from the operating mode operation, affect the system configuration deviation and save energy and reduce the cost, improve economy.
5. because the irregular operating of desulphurization system will cause the pollution of atmospheric environment, the problem of environmental protection.
6. former pipe material is the 10CrMoAl low alloy steel, and anticorrosion employing sacrificial anode and the anticorrosion scheme that is coated with corrosion-inhibiting coating and is combined are without filter.
Cleaning degree direct influence to impurity such as marine growths in the desulfurizing tower spray system arrives desulfuration efficiency, simul relation is to the height of power plant's Air Pollutant Emission Index, more be related to the healthy of surrounding resident, dangerous large, affects safety production and atmospheric environment.
