Technical field
The invention belongs to technical field of electric power, particularly relate 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 technology
With implementing continuing to increase of national environmental protection policy dynamics in power industry, Thermal generation unit must time limit install additional Wet desulphurization device.The environmental protection policy of response country of Ge great thermoelectricity group, strengthens flue gas desulfurization dynamics, progressively makes respective power plant Smoke density reaches the environmental protection standard of national regulation.
Owing to being all 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 anticorrosive specialty.It is faced with now the big of the whole industry Scale desulfurization project, whole power industry, in face of thing followed heavy corrosion, also lacks the enough understanding to corrosion harmfulness. During installing wet desulphurization device additional, particularly relating to desulfurizing tower, flue and chimney anticorrosion corrosion material and anticorrosion During scheme, being affected by various reasons, result causes substantial amounts of chimney anticorrosion erosion project quality problems occur, to power industry band Carry out serious economic loss, and leave serious potential hazard to the safety in production of power plant.
Before wet desulphurization, coal unit discharge is the flue gas without desulfurization, enters the flue-gas temperature of chimney on 125 DEG C of left sides Right.With this understanding, inner wall of stack is in drying regime, and flue gas does not directly produce corrosion to inner wall of stack material.Install wet method additional After desulfurizer, discharge is wet flue gas.If without flue gas heat-exchange unit heat temperature raising, enter the flue-gas temperature of chimney 50 ± 5 DEG C, inner wall of stack has serious condensation, and the condensation acid solution of generation is trickled downwards along barrel.The temperature of acid solution when 40 DEG C～50 DEG C, Strong especially to the corrosivity of structural material.As a example by steel, etch ratio when 40 DEG C～50 DEG C exceeds when 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, belong to highly acid state.If wet flue gas is for the corrosion rate of unlike material：The corrosion rate of Q235A steel is high Reach 159.54mm/～200.00mm/；The stainless corrosion rate of 10CrMnCuTi is also up to 23.9268mm/；These Actual test data have 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, it to the corrosion rate of concrete is：Corrosion rate for C25 concrete is 8mm/10 days；Corrosion for C30 concrete Speed is 2.4mm/10 days；Corrosion rate for C50 concrete is 2.4mm/10 days.
