Specific construction technique is as follows:
One, early-stage preparations
First purging medium is coated with to tank body 1 and removes greasy dirt, drying and rear dust storm processing of rust removing is carried out to inwall, reaffirming whether have greasy dirt, if any then using purging medium reheat treatment, until without after greasy dirt, dry.Tank inside face is checked comprehensively, the part of inner wall corrosion disappearance is repaired, filled and led up.
Two, tank body local flow improvement
After tank skin process completes, before not doing anticorrosion inwall, bottom tank body 1, a DN50 flange hole 14 need be opened from 100mm place at the bottom of tank, steel flange 15 1 is installed.After inner wall construction completes, carry out vacuum detecting by this flange hole 14 pairs of inwalls and outer wall, require that degree of vacuum reaches≤-0.050MPa, empty 24 hours of fidelity.Detect qualified after, at this flange hole 14 place, automated fluid detection probe 16 1 is installed, signal access operation room.After signal has adjusted, this construction technology completes, and can handle completion and apply for checking and examination.
Three, inner wall construction
1), tank skin construction technology
Smear a bed interface resin at tank body 1 inwall, thickness 0.5mm, solidify to form resin bed 5; The artificial 3D fabric pasting 1000 mm to 1300 mm from tank deck 3 to the tank end 2 from top to down, then slitless connection repeats to paste 3D fabric in the direction of the clock, until tank skin has all covered, thickness 3 mm to 4mm, wherein be not less than 3 mm with tank body gap, wait for and solidify to form 3D tissue layer 6 completely.After solidification, check and repair 3D tissue layer 6, after having repaired, with short yarn cutting and resin, spraying operation being carried out to the surface of 3D tissue layer 6, waiting for and solidify to form protective layer 7 completely.According to technological requirement, according to the parameter such as corrosive property of the diameter of tank body, the degree that is corroded, storage medium, calculate High molecular material layer thickness, then start to stitch fiber cloth, often open the size of cloth between 1200mm to 2000.With glue spraying by the cloth made from tank deck to tank at the bottom of from top to down successively slitless connection be bonded at tank skin, then clockwise direction slitless connection repeats above operation once, form scrim cloth 8, one deck flow-guiding screen 18 can be added at the upper surface of layer of cloth, be convenient to resin guide, and then seal in the surrounding of tank skin scrim cloth 8 with sealing joint strip 9, imbed mozzle 10 and glue conveying box 11 by threeway, stick vacuum film 12.With vacuum pump evacuation, check whether sealing, require that degree of vacuum reaches≤-0.080MPa.Leak hunting errorless, after vacuumizing, configure resin in proportion, auxiliary by resin injection glue conveying box 11 by resin injector, wait to be solidified.After having solidified, carry out checking, repairing.Repeat above operation successively, until tank skin construction terminates.The anticorrosion inwall of High molecular material can be formed like this, make it inside tank body 1, form protective layer, play anticorrosion, buffer action, prevent storage medium from directly producing 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 interface resin formation resin bed 5, by technological requirement, is stuck with paste by fiber cloth slitless connection and forms tank deck scrim cloth 13 at tank deck.
3), construction technology at the bottom of tank
Basic identical with the inwall of tank body 1, it is particularly to be noted that process tank skin bottom 5mm place 3D fabric, break mouth, to guarantee to communicate with tank skin space at the bottom of tank.
The present invention, by setting up the anticorrosion inwall of High molecular material, can possess double protection, and set up detecting device, and energy is detection of leaks point in time, after protective layer has spot failure, can send warning at once, avoid medium to corrode tank body, can increase the service life.
