Abstract
The invention discloses an antiseptic processing method for a capping part of a brick lining chimney, which comprises the following steps: washing a capping area at the chimney top with high-pressure water to remove impurities; repairing gaps of capping concrete bricks or locally leveling and drying; spraying, blade-coating, brush-coating or roller-coating a polyfluorine organic lining antiseptic material layer on the capping surface; and finally maintaining. In the method, antiseptic processing targeting an expansion joint part is performed by using elastic material, thereby solving the problems of leak tightness and thermal expansion at the same time. The method can perfectly eliminate thermal stress generated by fluctuation of smoke temperature, cannot damage the antiseptic layer and eradicates leakage of condensate.
Description
Technical field
The present invention relates to the preservative treatment technology of the brick lining chimney of industries uses such as steam power station, chemical industry and metallurgy.
Background technology
For the brick lining chimney that industries such as steam power station, chemical industry and metallurgy are used, preservative treatment is an important engineering.And in the internal construction of chimney, special preservative treatment need be carried out in some special positions.The chimney concrete bears down on one the position in the chimney top, and as shown in Figure 1, bearing down on one 21 is flue gas and atmosphere contacts site in the chimney, and its main effect is that chimney barrel and liner are sealed and protect, and improves its structural stability.22 is chimney outer walls among the figure, the 23rd, and chimney isolation layer, the 24th, proof chimney lining brick made.Present brick chimney structure two parts that mainly contain that concrete bears down on one and cast iron bears down on one that bear down on one.The position flue gas is among the strong interchange of heat always owing to bear down on one, and condensed fluid is serious, therefore must carry out specially treated.The topmost problem of preservative treatment of bearing down on one at present is, structure does not obtain enough understanding to bearing down on one, adopt the processing method identical with chimney barrel, cause existing the anti-corrosion material at flexible handing-over seam position to produce cracking or crackle, thereby produce anticorrosion inefficacy and seepage phenomenon, the chimney liquid that has directly leaks into insulation layer, makes the failure of bed rearrangement chimney anticorrosion.
Summary of the invention
The objective of the invention is to problem at the prior art existence, the method for anticorrosion treatment that a kind of concrete of brick lining chimney bears down on one is proposed, adopt poly-fluoropolymer organic lining anticorrosive material to carry out preservative treatment, thereby overcome owing to ignore the chimney concrete structure that bears down on one, stereotyped, the anticorrosion failure and the leakage problems that do not have the specific aim corrosion protection design to cause.
The present invention is directed to concrete bears down on one and cast iron bears down on one, the aseptic technic scheme is respectively as follows:
The concrete method for anticorrosion treatment that bears down on one
When (1) whole inner wall of stack being carried out high pressure water washing, high pressure water washing is also carried out in the zone of bearing down on one, top, remove the chimney impurity such as the unconsolidated formation at position, floating ash that bear down on one;
(2) adopt material for repairing such as potassium silicate clay, resin-bonded mastic, silicone rubber kinds high temperature elastic bonding encapsulant chimney to be beared down on one repair or levelling;
(3) spraying, blade coating, brushing or roller coating gather fluoropolymer organic lining anticorrosive material VP3-2, thickness 0.5-1.5mm;
(4) maintenance: room temperature: 1-3 days, or heat: after 50-80 ℃ of maintenance 3-8 hour, again at 100-150 ℃ of maintenance 12-48 hour.
The cast iron method for anticorrosion treatment that bears down on one
(1) the water flushing is carried out at the position of bearing down on one, and adopted manual removal to root out the mortar and the acid resistant adhesive mortar in handing-over seam zone, remove impurity in the handing-over seam;
(2) in the cast iron seam that bears down on one, pour into silicone rubber kinds high temperature elastic bonding encapsulant; And at the together poly-fluoropolymer organic lining anticorrosive material VP3-2 of silicone rubber kinds high temperature elastic bonding sealant surface brushing, thickness 0.3-0.5mm;
(3) at chimney outer wall brushing three road chlorinated rubber paints, thickness 80-120 micron;
(4) the position inner wall of stack that bears down on one carries out preservative treatment by chimney barrel technology;
(5) maintenance: room temperature: 1-3 days, or heat: after 50-80 ℃ of maintenance 3-8 hour, again at 100-150 ℃ of maintenance 12-48 hour.
Wherein, high temperature elastomeric materials such as the also available silicone adhesive of silicone rubber kinds high temperature elastic bonding encapsulant, fluorosioloxane rubber, polyurethane adhesive replace.
Wherein poly-fluoropolymer organic lining anticorrosive material adopts the poly-fluoropolymer organic lining anticorrosive material of announcing among the Chinese invention patent document CN101891993A " the poly-fluoropolymer organic lining anticorrosive material and the processing method of chimney, flue and other pipeline and container ", this material is made up of A and two kinds of components of B, the A component is to be raw material by fluorine-containing rubber earlier, adding stabilizing agent and reinforcing filler again carries out mixing, form elastomeric compound, make solvent with ketone, ester class or alcohols then, putty type rubber cement is made in dissolving, adds filler therein again and auxiliary agent is made; The B component is additive and organic solvent; After A, B component mix, be coated with and be contained in by the preserver surface, sulfuration at room temperature forms anticorrosive coat, reaches anticorrosion purpose.The product code name that the applicant gives is VP3-2.
Adopt above-mentioned processing method, to adopting elastomeric material to carry out preservative treatment, can well solve sealing and thermal expansion problem simultaneously targetedly the position, shrinkage joint.This method fine elimination of energy has been stopped condensate liquid seepage phenomenon because the thermal stress that the fluctuation of cigarette temperature produces can not cause anticorrosive coat to destroy.This method is practical application on a plurality of chimney anticorrosion projects, and effect is obvious.
