Description
Technical field
The utility model relates to a kind of anticorrosion protection against erosion spraying layer pipeline for spray system in absorption tower and system, belongs to industrial absorbent tower technical field of desulfurization.
Background technology
Maximum pyramidal structures applied in process for flue gas desulfurization by limestone/lime-gypsum wet by spray column, by the downward spraying (Bidirectional nozzle can be sprayed up and down) of Multi-layer sprinkling layer simultaneously, contacts the SO absorbed wherein with flue gas adverse current
2, owing to there being Multi-layer sprinkling layer, the spray coverage rate on cross section, absorption tower can reach very high, and every layer of corresponding slurry circulating pump of spraying layer is for slurry.Because circulating pump is more with the spray number of plies, especially for medium-high sulfur coal, therefore absorption tower is general higher, and slurry pool of absorption tower also power consumption that is comparatively large, circulating pump is higher, but spray column has the following advantages: 1) desulfuration efficiency is high; 2) system reliability and availability high; 3) system suitability is strong.
But the wear-resisting protection against erosion of desulfuration absorbing tower spraying layer is a weak link in desulphurization system always, the high speed slurries continuous punching of tower inner nozzle ejection brushes spraying layer brace summer and causes anticorrosive coat to destroy, brace summer distortion, perforation.For solving problems, proposing in existing report and multiplely improving Corrosion prevention scheme, such as, absorption tower spray system brace summer being optimized, brace summer and inner wall of tower are connected into overall structure; Washing away brace summer is reduced by the position of nozzle near adjustment brace summer; By improving, anti-corrosion material performance improvement is anti-washes away intensity.But, under the washing away for a long time of nozzle, anticorrosive coat still can come off, the problem that brace summer is perforated, is out of shape occurs, prevent washing away of brace summer by improving the position of nozzle near brace summer simultaneously, this kind of way cannot reach designing requirement because of construction accuracy problems, so difficulty is very large, brace summer protection against erosion effect can not be ensured.
For solving the problem, the utility model provides a kind of for the spraying layer pipeline in absorption tower and system.
Summary of the invention
The utility model, by carrying out design optimization to absorption tower spraying layer support beam structure and anticorrosion structure, solves absorption tower spraying layer brace summer and is washed, and brace summer is bored a hole, anticorrosive coat comes off problem.
For achieving the above object, the utility model provide firstly a kind of for the spraying layer pipeline in absorption tower:
For the spraying layer pipeline in absorption tower, comprise supervisor and be positioned at the brace summer being responsible for tube wall both sides, described brace summer side and supervisor are by Interal fixation, and opposite side is provided with anticorrosive coat, is also provided with pipe clamp between described supervisor and brace summer;
In a preferred embodiment of the present utility model, described anticorrosive coat is line with rubber layer.
In a preferred embodiment of the present utility model, described anticorrosive coat is also provided with polypropylene board outward.Because polypropylene material has stronger corrosion-resistant and anti-ly wash away performance, thus when described polypropylene board is used at the location external easily washed away by nozzle, can well play and prevent brace summer from being washed away by spray.In the present invention's preferred embodiment, described polypropylene board is U-shaped.
In a preferred embodiment of the present utility model, described supervisor and the connected mode of brace summer adopt punched-type mounting means.
The utility model provides a kind of for the spraying layer system in absorption tower on the other hand, the nozzle comprising supervisor, be positioned at the brace summer of supervisor tube wall both sides, arm and be connected with arm, described brace summer side and supervisor pass through Interal fixation, opposite side is provided with anticorrosive coat, also be provided with pipe clamp between described supervisor and brace summer, described anticorrosive coat is also provided with polypropylene board outward.
In a preferred embodiment in accordance with this invention, described nozzle is arranged on brace summer both sides.
In a preferred embodiment in accordance with this invention, described nozzle and the spacing of brace summer are 400-550mm.When spray liquid is after nozzle ejection, according to the spray radius of spray liquid, while described spacing can ensure spray desulfurized effect, what contact with spray liquid at supporting layer washes away place, owing to being provided with anticorrosive coat and polypropylene board, reaching and decrease spraying layer washing away and corroding pipeline.
Compared with the spraying layer in existing absorption tower, the utility model has following characteristics:
(1) the utility model is studied and numerical simulation by experiment, thus determine the key structure that spray system is arranged and parameter, achieve while maximizing spray desulfurized effect, decrease spraying layer washing away and corroding pipeline, add the service life of pipeline.
(2) scheme of the anticorrosion protection against erosion of the utility model optimal design spraying layer brace summer pattern and brace summer, the final complete set technology forming the anticorrosion protection against erosion being applicable to variety classes absorption tower spraying layer.
(3) the utility model solves absorption tower spraying layer brace summer for the spraying layer structure in absorption tower and system be washed by providing a kind of, and brace summer perforation, anticorrosive coat come off problem.
