Abstract
The utility model relates to an anti-corrosion system of a spraying area of a desulfurizing absorption tower. The anti-corrosion system comprises tower walls and slurry spraying pipe networks, wherein the spraying area of the desulfurizing absorption tower is formed by the slurry spraying pipe networks and the tower walls, glass flake anti-corrosion layers are arranged on the tower walls, and a layer of PP strengthening protection plate is lined on the glass flake anti-corrosion layer below the central line of each slurry spraying pipe network by 500 to 1200mm. By using the anti-corrosion system, the problems that the glass flake anti-corrosion layers fall off caused by high-speed continuous washing of nozzles on the slurry spraying pipe networks, then the cutting through of the cylinder walls of the absorption tower is caused, and the slurry leakage and damage and deformation of a tower body are caused are solved, additionally, the PP strengthening protection plate has the advantages of rapidity in construction and cost saving, after a machine is stopped, the PP strengthening protection plate can be replaced at any time according to specific washing conditions, the cost waste caused by overhaul of the spraying area for a plurality of times is directly reduced, the increase of the number of layers of operation circulating pumps due to change of nozzles angles is reduced, and the power consumption is reduced.
Description
Technical field
The utility model relates to desulfuration absorbing tower anticorrosion technique field, relates in particular to a kind of desulfuration absorbing tower spray district anti-corrosion system.
Background technology
In coal steam-electric plant smoke Wet Process of FGD Project and improvement project thereof, the anticorrosion protection against erosion in spray region, absorption tower is a weak link always, glass flake decay resistance brilliance, but not resistance to erosion, the high speed slurries of nozzle ejection are washed into absorption tower barrel and can wash away fast glass flake anticorrosive coat and then penetrate tower wall, and the welding steel of tower wall can be adhered at most i.e. breakage in about a week, thereby causes desulfurization slurry to leak, system is stopped transport, and has a strong impact on service life of equipment.
Absorption tower barrel occurs after breakage, and conventional treatment mode is: remove anticorrosive coat in desulfurizing tower, utilize sanding machine polishing barrel steel plate, afterwards damaged area is re-started to repair by welding, after having repaired, then it is anticorrosion that repairing area is carried out to glass flake.Though this type of mode can solve absorption tower barrel damaging problem, cures the symptoms, not the disease, defect is obvious, and there are the following problems: (1) maintenance period, need stop desulfurizing tower, and cause system to stop transport; (2) in tower when work high above the ground, anticorrosion cleaning, barrel is repaired wastes time and energy, and difficulty of construction is large; (3) have repeatability, after reparation, the problem that spray region barrel washes away still exists, and after operation a period of time, restoring area or other region still there will be damaging problem, extremely trouble.
Utility model content
The purpose of this utility model is to provide a kind of desulfuration absorbing tower spray district anti-corrosion system, solved because nozzle high-speed and continuous is washed away and caused anticorrosive coat repeatedly to come off, the high speed slurries of nozzle ejection penetrate tower wall and the technical problem of stoppage in transit is frequently keeped in repair on the absorption tower of causing.
The technical scheme that the utility model is taked is: a kind of spray district anti-corrosion system of desulfuration absorbing tower, comprise tower wall and slurries spray pipe network, described slurries spray pipe network and described tower wall form the spray district of desulfuration absorbing tower, on described tower wall, be provided with glass flake anticorrosive coat, below described each slurries spray pipe network center line, on the glass flake anticorrosive coat at 500 ~ 1200mm place, liner one deck PP strengthens protective plate again.
In such scheme, described PP strengthens protective plate piecemeal and is arranged on described glass flake anticorrosive coat.
In such scheme, the both sides of the edge that described every PP strengthens protective plate are provided with 90 ° of flange, on described 90 ° of flange, have bolt hole, and every adjacent two PP strengthen protective plate and link together by described 90 ° of flange bolts.
In such scheme, on described tower wall, being welded with bolt and the material that material is 1.4529 steel alloys is the draw-in groove of SS32205 austenite two-phase alloys steel, it is the nut of 1.4529 steel alloys and being fixed on described tower wall of described bolt by material that described PP strengthens protective plate upper end, and described PP strengthens protective plate lower end and is fixed on described draw-in groove.
The beneficial effects of the utility model are: solved because slurries spray pipe network top nozzle high-speed and continuous is washed away and caused glass flake anticorrosive coat to come off; and then penetrate absorption tower barrel cause slurries leak problem; simultaneously; the construction of PP enhancing protective plate is fast, cost saving; after shutdown, can, according to the situation of washing away, change at any time; the direct minimizing expenses of labour waste that repeatedly cause in maintenance spray region, minimizing is changed nozzle angle and is increased the advantages such as the operation circulating pump number of plies and power consumption.

Detailed description of the invention
As shown in Figure 1, desulfuration absorbing tower spray of the present utility model district anti-corrosion system comprises tower wall 1 and slurries spray pipe network 7, described slurries spray pipe network 7 and described tower wall 1 form the spray district of desulfuration absorbing tower, on described tower wall 1, be provided with glass flake anticorrosive coat 2, the bolt 4 and the material that on described tower wall 1, are also welded with material and are 1.4529 steel alloys are the draw-in groove 5 of SS32205 austenite two-phase alloys steel, and on the glass flake anticorrosive coat below described each slurries spray pipe network 7 center lines, liner one deck PP strengthens protective plate 3.It is the nut (6) of 1.4529 steel alloys and being fixed on described glass flake anticorrosive coat 2 of described bolt (4) by material that described PP strengthens protective plate 3 upper ends, and described PP strengthens protective plate 3 lower ends and is fixed on described draw-in groove 5.Slurries spray pipe network 7 top nozzle high-speed and continuous are washed into PP enhancing protective plate 3 like this, have avoided directly washing away glass flake anticorrosive coat 2; Preferably, described PP strengthens protective plate 3 and can piecemeal arrangement be arranged on described glass flake anticorrosive coat 2, the both sides of the edge of every PP enhancing protective plate are provided with 90 ° of flange 8, on described 90 ° of flange 8, have bolt hole, every adjacent two PP strengthen protective plate 3 and link together by 90 ° of flange 8 bolts of both sides, like this after PP enhancing protective plate 3 parts are by high speed slurries erosion damage, can be very fast this fritter PP enhancing protective plate be changed, directly reduces the long-time cost waste causing in spray region of overhauling.Preferred, the top edge that described PP strengthens protective plate 3 can be arranged on the described slurries spray pipe network of distance 7 500mm-1200mm places, center line below, the slurries that slurries spray pipe network 7 ejects like this can just drop on PP to be strengthened on protective plate 3, the usable floor area of having saved PP enhancing protective plate 3, has reduced cost.
