Description
Technical field
The utility model relates to the corrosion protection system of a kind of thermal power plant Steel Inner Core of Chimney wet desulphurization.
Background technology
Along with the enhancing of public's environmental consciousness, national policy is also increasingly high to the requirement in the environmental protection, stands in the breach especially as the thermal power plant of environmental protection key monitoring object, discharging again after the thermal power plant needs carry out desulfurization and handle flue gas.Flue gas after the desulfurization is a wet flue gas; The corrosion type of its desulfurization wet flue gas comprises sulfuric acid, sulfurous acid, chloride, fluoride etc.; The flue gas grade is a severe corrosive, and low, the high humidity, little from pull out force of this cigarette temperature almost is in full operation under positive pressure state according to the theoretical calculation chimney.The condensate that the desulfurization smoke condensation forms has very strong corrosivity, and steel stack is worked under sour environment, corroded by the double action of flue gas pressures and humidity, even perforation, has a strong impact on chimney safe handling and structure durability.The utility model patent has proposed a kind of economical and practical, novel easily chimney anticorrosion way of enforcement in the chimney anticorrosion process.
The utility model content
The utility model technical problem to be solved provides the corrosion protection system of a kind of thermal power plant Steel Inner Core of Chimney wet desulphurization, efficiently solves the anticorrosion problem of chimney.
The utility model technical problem to be solved realizes through following technical scheme:
The corrosion protection system that a kind of thermal power plant Steel Inner Core of Chimney desulfur technology is transformed is characterized in that: comprise that stack shell corrosion protection system, deflector corrosion protection system and chimney bottom bottom flue wash away district's corrosion protection system for 30 meters high to absolute altitude;
The barrel of said stack shell corrosion protection system inwardly sets gradually steel cylinder repair layer, heat-proof epoxy anticorrosive paint layer, KP1 acid resistant adhesive mortar layer and light vitreous acid-proof ceramics face brick layer;
Said deflector and flue bottom corrosion protection system and chimney bottom all inwardly set gradually heat-proof epoxy anticorrosive paint layer, KP1 acid resistant adhesive mortar layer, light vitreous acid-proof ceramics face brick layer, the bonding bed of material of organosilicon and high strength vitreous acid-proof ceramics face brick layer to the barrel that 30 meters high of absolute altitudes wash away district's corrosion protection system.
Between the neighbouring two-layer face brick of the light vitreous acid-proof ceramics face brick layer of said stack shell corrosion protection system stagger in the mortar joint position.
High strength vitreous acid-proof ceramics face brick layer is set on the light vitreous acid-proof ceramics face brick layer of junction in the said stack shell, connects fixing through the bonding bed of material of organosilicon.
The beneficial effect of the utility model:
The utility model patent be to the thermal power plant Steel Inner Core of Chimney adopt when anticorrosion a kind of economical and practical, implement novel anticorrosion system easily; This corrosion protection system utilizes the good adhesive property of KP1 acid resistant adhesive mortar; Prevent corrosive liquids infiltration erosion steel stack barrel effectively, light vitreous acid-proof ceramics brick can play effects such as the acid-proof burn into that arrives very much is wear-resisting, insulation simultaneously; The utlity model has convenient, the characteristics such as antiseptic property is good, good endurance of implementing.

Fig. 3 deflector and flue bottom layout drawing
Among the figure, 1-steel cylinder barrel, 2-heat-proof epoxy anticorrosive paint layer, 3-KP1 acid resistant adhesive mortar layer, the light vitreous acid-proof ceramics face brick of 4-, 5-steel cylinder repair layer, the bonding bed of material of 6-organosilicon, 7-high strength vitreous acid-proof ceramics face brick layer, 8-deflector
The specific embodiment
Fig. 1-3 shows, the corrosion protection system that a kind of thermal power plant Steel Inner Core of Chimney desulfur technology is transformed is characterized in that: comprise that stack shell corrosion protection system, deflector corrosion protection system and chimney bottom bottom flue wash away district's corrosion protection system for 30 meters high to absolute altitude;
The steel cylinder barrel 1 of said stack shell corrosion protection system sets gradually steel cylinder repair layer 5, heat-proof epoxy anticorrosive paint layer 2, KP1 acid resistant adhesive mortar layer 3 and light vitreous acid-proof ceramics face brick layer 4;
Said deflector 8 all inwardly sets gradually heat-proof epoxy anticorrosive paint layer 2, KP1 acid resistant adhesive mortar layer 3, light vitreous acid-proof ceramics face brick layer 4, the bonding bed of material 6 of organosilicon and high strength vitreous acid-proof ceramics face brick layer 7 with flue bottom corrosion protection system and chimney bottom to the barrel that 30 meters high of absolute altitudes wash away district's corrosion protection system.
Between the neighbouring two-layer face brick of the light vitreous acid-proof ceramics face brick layer 4 of said stack shell corrosion protection system stagger in the mortar joint position.
High strength vitreous acid-proof ceramics face brick layer 7 is set on the light vitreous acid-proof ceramics face brick layer 4 of junction in the said stack shell, connects fixing through the bonding bed of material 6 of organosilicon.
Specific practice is: form steel cylinder repair layer 5 after earlier original corrosion-proof lining being removed the reparation steel cylinder; Polishing steel inner cylinder substrate, chimney inwardly is distributed with from barrel successively: chimney steel cylinder barrel 1, the thick heat-proof epoxy anticorrosive paint of 3mm layer 2, the thick KP1 acid resistant adhesive mortar of 4mm layer 3, the light vitreous acid-proof ceramics face brick 4 that 50mm is thick.Chimney deflector 8 and flue bottom and chimney bottom inwardly are distributed with from barrel to 30 meters high districts of washing away of absolute altitude successively: chimney wall, the thick heat-proof epoxy anticorrosive paint of 3mm layer 2, the thick KP1 acid resistant adhesive mortar of 4mm layer 3, the thick high strength vitreous acid-proof ceramics face brick layer 7 of light vitreous acid-proof ceramics face brick layer 4,30mm that 50mm is thick.Wherein the thick potassium water of 4mm acid resistant adhesive mortar layer 3, require the weight of the used bonding material of every square meter to be not less than 11kg, and will stagger in face brick mortar joint position.The adhesive property that the KP1 acid resistant adhesive mortar is good prevents corrosive liquids infiltration erosion steel stack barrel effectively, and light vitreous acid-proof ceramics brick can play effects such as the acid-proof burn into that arrives very much is wear-resisting, insulation simultaneously.
