Technical field
The invention belongs to technical field of electric power, more particularly to a kind of chimney of electric plant inner wall anti-corrosive antiseepage liner and utilize vertical Straight inversion method realizes the field erected method of chimney.
Background technique
With continuing to increase for national environmental protection policy dynamics is implemented in power industry, Thermal generation unit must time limit installation Wet desulphurization device.The environmental protection policy of major thermoelectricity group response country, increases flue gas desulfurization dynamics, gradually makes respective power plant Smoke density reaches the environmental protection standard of national regulation.
Due to being discharge high-temperature flue gas before China's Thermal Power Generation Industry, at this moment flue gas is lighter to the corrosion of flue, chimney.State Interior power industry is substantially not provided with materials specialty, let alone anticorrosion material profession.It is faced with the big of the whole industry now Scale desulfurization project, entire power industry also lack the enough understanding to corrosion harmfulness in face of the following heavy corrosion. During installing wet desulphurization device additional, especially it is being related to desulfurizing tower, flue and chimney anticorrosion corrosion material and anticorrosion It when scheme, is influenced by various reasons, as a result causes a large amount of chimney anticorrosion erosion project quality problems occur, give power industry band Carry out serious economic loss, and leaves serious potential hazard to the safety in production of power plant.
Before wet desulphurization, coal unit discharge be the flue gas without desulfurization, into chimney flue-gas temperature on 125 DEG C of left sides It is right.With this condition, inner wall of stack is in drying regime, and flue gas does not generate corrosion directly to inner wall of stack material.Install wet process additional After desulfurizer, discharge is wet flue gas.If without flue gas heat-exchange unit heat temperature raising, into chimney flue-gas temperature 50 ± 5 DEG C, inner wall of stack has serious moisture condensation, and the moisture condensation acid solution of generation is trickled downwards along barrel.The temperature of acid solution at 40 DEG C~50 DEG C, It is especially strong to the corrosivity of structural material.By taking steel as an example, etch ratio at 40 DEG C~50 DEG C is higher by other temperature About 3~8 times.After wet desulphurization, when desulfuration efficiency reaches Theoretical Design value 95%, the pH value of the acid condensate liquid of inner wall of stack It is 1.9~2.2, belongs to highly acid state.If wet flue gas is for the corrosion rate of unlike material: the corrosion rate of Q235A steel is high Up to 159.54mm/~200.00mm/；The corrosion rate of 10CrMnCuTi stainless steel is also up to 23.9268mm/；These Actual test data has absolutely proved that this condensation water has very strong corrosive power.When the concentration of inner wall of stack dilute sulfuric acid is 15% When, to the corrosion rate of concrete are as follows: the corrosion rate for C25 concrete is 8mm/10 days；Corrosion for C30 concrete Rate is 2.4mm/10 days；Corrosion rate for C50 concrete is 2.4mm/10 days.
