Description
Technical field
The utility model belongs to anti-corrosive apparatus technical field, is specifically related to a kind of preparing structure of desulfurizing tower inner liner rubber defect.
Background technology
In China, Desulfurization of Wet Limestone-gypsum technique has become the leading technique of flue gas desulphurization, and absorption tower is the nucleus equipment in wet desulphurization device, the absorption tower lining material used at present mainly contains glass resin flake, rubber and Langaloy three kinds, because Langaloy is expensive, carry out anticorrosion at other position many uses glass resin flake of equipment and rubber lining; Butyl rubber is the one in rubber, and due to pending methyl group dense arrangement in its strand, permeability is extremely low, is only 1/10 ~ 1/15 of General Purpose Rubber, lacks double bond in butyl rubber molecules structure, and pendant methyl distribution density is larger; Above design feature determines butyl rubber and has that air penetrability is low, resistance to chemical attack, heat endurance is high, antiscour corrosivity is good, anticorrosion stress-resistant, damping property are good and and carbon steel between have a series of good characteristics such as good bond properties.
But line with rubber construction requirement construction technology is higher, careless slightlyly just easily leave hidden danger of quality, the quality problems such as deuterogenesis's bubbling, cracking; And line with rubber position is often in absorption tower spraying layer brace summer, shower ejection slurries, containing a large amount of solid particle in slurries, causing a large amount of erosive wears to being washed position, causing the local damage of butyl rubber, affect the normal operation of equipment; Therefore design a kind of convenient, structure is simple, line with rubber defect mending scheme that is with low cost, dependable performance will become an important topic of anti-corrosive apparatus technical field.
Utility model content
The purpose of this utility model solves the problem, provide that a kind of structure is simple, easy construction, with low cost, dependable performance the preparing structure of desulfurizing tower inner liner rubber defect.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of preparing structure of desulfurizing tower inner liner rubber defect, comprise absorption tower steel matrix, butyl layers covers in the steel matrix of absorption tower, vinylite scale is filled in butyl layers and repairs in breach and to be connected with absorption tower steel matrix, and fiberglass enhancement Layer covers on vinylite scale and the area of fiberglass enhancement Layer is greater than the area of vinylite scale.
Preferably, the thickness of vinylite scale is equal with the thickness of butyl layers.
Preferably, butyl layers repairs the edge gradient of breach is 30 ~ 45 degree.
Preferably, the quantity of fiberglass enhancement Layer is 6 ~ 8 layers.
Preferably, the outer surface of outermost fiberglass enhancement Layer scribbles finish paint.
Preferably, the area of fiberglass enhancement Layer is from the bottom up in increasing progressively relation.
The beneficial effects of the utility model:
1, by vinylite scale, breach is repaired to butyl layers and carry out repairings cover glass steel enhancement Layer, effectively can solve the problem that line with rubber defect difficulty is repaired, and structural anticorrosion after repairing is effective, dependable performance.
2, low, with low cost, the easy construction of this preparing structure difficulty of construction, the repairing work of each position line with rubber defect can be tackled.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model preparing structure;
Description of reference numerals: 1, absorption tower steel matrix; 2, butyl layers; 3, vinylite scale; 4, fiberglass enhancement Layer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
As shown in Figure 1, the preparing structure of the desulfurizing tower inner liner rubber defect in the present embodiment comprises absorption tower steel matrix 1, butyl layers 2, butyl layers repairing breach, vinylite scale 3 and fiberglass enhancement Layer 4, butyl layers 2 covers in absorption tower steel matrix 1, vinylite scale 3 is filled in butyl layers and repairs in breach and to be connected with absorption tower steel matrix 1, and the thickness of vinylite scale 3 is equal with the thickness of butyl layers 2; Fiberglass enhancement Layer 4 covers on vinylite scale 3 and the area of fiberglass enhancement Layer 4 is greater than the area of vinylite scale 3, the quantity of fiberglass enhancement Layer 4 is 6 ~ 8 layers, the area of fiberglass enhancement Layer 4, from the bottom up in increasing progressively relation, the outer surface of outermost fiberglass enhancement Layer 4 scribbles finish paint; In order to increase the contact area of vinylite scale and butyl layers, the edge gradient that butyl layers repairs breach is 30 ~ 45 degree.
The method making this preparing structure is:
Step 1, on butyl layers 2, there is the place of line with rubber defect that the colloid of bubbling and cracking is polished off by sanding machine, until expose absorption tower steel matrix 1.
Step 2, repair at the butyl layers that polish the gradient that gap edge sanding machine polish 30 ~ 45 degree.
Step 3, vinylite scale 3 is filled into butyl layers and repairs in breach and make the surface of vinylite scale 3 consistent with the height of former butyl layers 2.
Step 4, make fiberglass enhancement Layer 4 on the surface of vinylite scale 3, making 6 ~ 8 layers altogether, the area of fiberglass enhancement Layer 4 is from the bottom up in increasing progressively relation.
After fiberglass enhancement Layer 4 solidification of step 5, outermost layer, at its external coating finish paint.
Those of ordinary skill in the art will appreciate that, embodiment described here is to help reader understanding's principle of the present utility model, should be understood to that protection domain of the present utility model is not limited to so special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combination of not departing from the utility model essence according to these technology enlightenment disclosed in the utility model, and these distortion and combination are still in protection domain of the present utility model.
