Description

A kind of inner wall of stack anticorrosion high-molecular polythene layer
Technical field
This utility model relates to a kind of inner wall of stack anticorrosion high-molecular polythene layer, belongs to chimney anticorrosion technical field.
Background technology
In the industrial production, by the structures such as flue, chimney, aiutage, scrubbing tower etc. of the various waste gas of high altitude discharge, All there is pollution and Anticorrosion Problems in great majority." fossil-fuel power plant atmospheric pollutant emission standard " (GB13223-2011) new standard is big Width has tightened up the emission limit of nitrogen oxides, sulfur dioxide and flue dust, close to or up the requirement of developed countries and regions.
Thermal power plant in early days of China does not add desulfurizer, and chimney have employed armored concrete liner tile masonry in a large number.With The commonly used of the domestic relevant regulation for environmental conservation and the execution of decree and wet desulfurizing process, these chimneys are carried out Desulfurizing fly ash is the most imperative.But wet desulphurization brings chimney and flue significant corrosion problems.After desulfurization, whether install additional Flue gas heat-exchange unit (GGH), flue-gas temperature is below acid dew-point temperature, although sulfur dioxide in flue gas, sulfur trioxide content reduce, But these sour gas, especially sulfur trioxide will be dissolved in the water, form acid solution so that flue gas is at back-end ductwork and cigarette Chimney inwall condenses, and for the inner wall of stack of different structure form, all has corrosion in various degree to occur.As can be seen here, thermal power plant Chimney still can be caused heavy corrosion by flue gas after desulfurization, for ensureing the properly functioning of power plants generating electricity additional, chimney is installed anti-corrosion measure Particularly necessary.
The anti-corrosion material of current domestic entrance chimney anticorrosion improvement project mainly has brushing class, patch block class, liner class.Brushing Class: OM, glass flake and Sa Weizhen etc., be characterized in that cost is relatively low, and short construction period is easy to maintenance, but service life is short, Poor durability.Patch block class: foam glass brick, acidproof brick and vitreous ceramic brick etc., be characterized in heatproof, resistance to ooze, moisture-proof, corrosion resistant The characteristics such as erosion, aging resistance are good, and cost is general, but construction requirement is high, difficulty big, and life-time service easily comes off, for old chimney Transform relatively difficult to achieve.Liner class: titanium plate alloy lining etc., is characterized in corrosion-resistant, heat resistance good, and major defect is construction difficulty Degree is greatly, it is impossible to reaching whole welding requirements of alloy, life-time service there will be commissure steel plate corrosion Seepage, cost Expensive.
Chinese patent literature CN103982079A discloses the construction method of the anti-corrosive apparatus of a kind of thermoelectricity chimney, including: Step 1, is welded into the load bearing support ring of loop configuration;Step 2, forms the supporting frame of cylindric rack;Step 3, it is achieved hinge Connect and cyclization, be spliced to form inner core corrosion-proof lining;Step 4, takes the fiberglass of 4-5 layer to mend to the glass epoxy place of being laterally hinged with Strong construction, first levelling with resin flake to the vertical splicing part of glass epoxy, then on the surface of stitching portion, carry out the glass of 4-5 layer Glass steel reinforcing construction is formed and seals.But, the service life of this anti-corrosive apparatus is short, poor durability.
