2nd, tank body local flow improvement
After the completion of tank skin process, before not doing anti-corrosion inwall, a DN50 methods need to be opened away from tank bottom 100mm in 1 bottom of tank body Flange aperture 14, installs steel flange 15 1.After the completion for the treatment of inner wall construction, vacuum inspection is carried out to inwall and outer wall by the flange hole 14 Survey, it is desirable to which vacuum reaches≤- 0.050MPa, fidelity is empty 24 hours.After detection is qualified, automatic liquid is installed at the flange hole 14 Body detection probe 16 1, signal access operation room.After the completion of signal adjustment, the construction technology is completed, and can be handled completion and be applied for checking and examination.
3rd, inner wall construction
1), tank skin construction technology
A bed boundary resin is smeared in 1 inwall of tank body, thickness 0.5mm solidify to form resin bed 5;Manually from tank deck 3 to tank The 3D fabrics of the mm of 1000 mm to 1300 are pasted at bottom 2 from top to down, and then slitless connection repetition stickup 3D is knitted in the direction of the clock Thing, until tank skin is all covered completing, 3 mm to 4mm of thickness, wherein being not less than 3 mm with tank body gap, wait is fully cured shape Into 3D tissue layers 6.After solidification, check and repair 3D tissue layers 6, after the completion of finishing, to the surface of 3D tissue layers 6 be chopped yarn and Resin carries out spraying operation, and wait is fully cured to form overcoat 7.According to technological requirement, according to the diameter of tank body, be corroded journey The parameters such as degree, the corrosivity of storage medium, calculate polymer material layer thickness, then start stitch fiber cloth, every cloth it is big It is little between 1200mm to 2000.With glue spraying, by the cloth for having sewed, from tank deck to tank bottom, slitless connection is bonded at tank successively from top to down On wall, then clockwise direction slitless connection repeats operation above once, forms scrim cloth 8, can add in the upper surface of layer of cloth One layer of flow-guiding screen 18, is easy to resin guide, and and then the surrounding with sealing joint strip 9 in tank skin scrim cloth 8 is sealed, by threeway Embedment mozzle 10 and glue conveying box 11, stick vacuum film 12.Vacuumized with vavuum pump, check whether sealing, it is desirable to vacuum Reach≤- 0.080MPa.Leak hunting errorless, after vacuumizing, configure resin in proportion, infused resin into resin injector auxiliary defeated In sebific duct 11, wait to be solidified.After the completion of solidification, carry out checking, repair.Above operation is repeated in, until tank skin construction terminates. Macromolecular material anti-corrosion inwall can so be formed so as to overcoat is formed on the inside of tank body 1, play anti-corrosion, buffer action, prevent Storage medium directly produces corrosion to inner tank wall, can increase the service life.
2), tank deck construction technology
Tank deck 3 adopts manual lay-up technique, after tank deck 3 smears a bed boundary resin formation resin bed 5, will by technique Ask, fiber cloth slitless connection is pasted and tank deck scrim cloth 13 is formed in tank deck.
3), tank bottom construction technology
Substantially it is identical with the inwall of tank body 1, it is accordingly required in particular to it is to be noted that 3D fabrics at the 5mm of tank skin bottom are processed, Break mouth, to guarantee that tank bottom is communicated with tank skin space.
The present invention by setting up macromolecular material anti-corrosion inwall, can possess double protection, and set up detection means, can and When detect leak point, warning can be sent at once, it is to avoid medium corrodes to tank body after overcoat has spot failure, can be extended Service life.
