Abstract
The invention relates to a large-scale glass reaction vessel or a glass lining storage tank, which belongs to the technical field of chemical processing equipment in the petrochemical industry. In order to solve technical problems, the invention adopts the technical proposal that a PP board is prepared and determined, ceramic surface treatment is performed, a stainless steel guide screw is welded, the PP board is drilled, healant is coated, a rubber gasket is pressed, the PP board is penetrated, and the PP tube head is welded. The equipment repaired through the method is characterized by long service life and simple and convenient method.
Description
Technical field
The claimed affiliated technical field of technical scheme of the present invention is petroleum chemical industry chemical industry equipment maintenance field, particularly large glass reactor, enamel basin etc.
Background technology
Glass-lined equipment is used very extensive in chemical industry because of its good acid and alkali-resistance anti-corrosive properties, but in use because improper use, bump or excessive temperature differentials or service life problem all can occur taking off the porcelain problem, will cause taking off the long-pending end reaction equipment that enlarges of porcelain facing and be penetrated and scrap in case take off the untimely repairing of porcelain.A 5M
3Glassed steel reaction vessels is worth ten thousand yuan of 4-5,5M
3Basin is worth ten thousand yuan of 2-3, and the equipment of this costliness is scrapped because of taking off porcelain integral body, and is unfortunately tangible.
And existing enamel healant method-senior all-purpose adhesive, in use healant or all-purpose adhesive be to the neutral medium favorable anti-corrosion effect, but to the strong acid and strong base environment, or the surface is subjected under the bigger situation of shearing force, very fast peeling or come off.
Summary of the invention
Technical problem to be solved by this invention be behind the glass-lined equipment small size porcelain-shedding repair at the strong acid and strong base environment, or the surface be subjected under the bigger situation of shearing force very fast aliquation or the technical barrier that comes off.
The technical scheme that the technical problem that the present invention solves is taked is:
(1) prepares:, determine the size (PP plate external form profile is than taking off the big at least 3cm of porcelain external form outline diameter) of PP plate (thick 15mm), generally with square or circle according to the shape and the size of taking off the porcelain position;
(2) take off the porcelain surface treatment: dip in clean wiping machine cloth and get watery hydrochloric acid or rare nitric acid and wipe and take off the porcelain surface derusting, after rust is removed,, dry naturally with the clear water flushing;
(3) soldering stainless steel leading screw: the stainless steel leading screw of intercepting certain-length, its length are 1-3 times of PP plate thickness, are welded on electric welding and take off the porcelain part, want during welding slowly prevent burst porcelain.Prevent that pad is higher than the enamel face, otherwise can't compress.
(4) PP twist drill hole:, determine the bore position of PP plate according to the leading screw welding position; After all the porcelain position is taken off in covering with the PP plate, the location, it is the position boring of PP plate that leading screw faces toward;
(5) healant is smeared: floating taking off the porcelain part with healant;
(6) rubber sheet gasket: cut and an identical rubber slab of PP plate size with scissors, after the perforation, rubber slab is evenly smeared one deck healant, is pressed in mend;
(7) PP plate: the PP plate is through on the leading screw, nut is screwed leading screw to the PP plate, the PP plate is not interspaced for four jiaos;
(8) welding PP tube head: save the PP tube head with one, be as the criterion can cover all nuts, at first an end that the PP tube head is covered the outside of nut with the 2mmPP plate welds, and makes a cover, covers nut then, and it is welded on the PP plate that compresses.
This method is used in takes off the long-pending diameter of porcelain facing≤25cm situation, and this enterprise is fine through practical effect, and originally need be warded off again again or renew equipment, adopt this method after, used 2-3 again.Often test to repairing the position, if after finding the aging corrosion on every side of PP plate, remove, same method is changed the PP plate.
Claims (1)
1. the method for chemical glass lining device porcelain-shedding repair, its feature may further comprise the steps:
(1) prepares:, determine that the PP plate thickness is that the PP plate external form profile of 15mm is than taking off the big at least 3cm of porcelain external form outline diameter, with square or circle according to the shape and the size of taking off the porcelain position;
(2) take off the porcelain surface treatment: dip in clean wiping machine cloth and get watery hydrochloric acid or rare nitric acid and wipe and take off the porcelain surface derusting, after rust is removed,, dry naturally with the clear water flushing;
(3) soldering stainless steel leading screw: the stainless steel leading screw of intercepting certain-length, its length are 1-3 times of PP thickness, are welded on electric welding and take off the porcelain part, want during welding slowly prevent burst porcelain, prevent that pad is higher than the enamel face, otherwise can't compress;
(4) PP twist drill hole:, determine the bore position of PP plate according to the leading screw welding position; After all the porcelain position is taken off in covering with the PP plate, location, the position boring of the PP plate that leading screw faced toward;
(5) healant is smeared: floating taking off the porcelain part with healant;
(6) rubber sheet gasket: cut and an identical rubber slab of PP plate size with scissors, after the perforation, rubber slab is evenly smeared one deck healant, is pressed in mend;
(7) PP plate: the PP plate is through on the leading screw, nut is screwed leading screw to the PP plate, the PP plate is not interspaced for four jiaos;
(8) welding PP tube head: save the PP tube head with one, be as the criterion can cover all nuts, at first an end that the PP tube head is covered the outside of nut with the 2mmPP plate welds, and makes a cover, covers nut then, and it is welded on the PP plate that compresses.
