Description
Technical field
The present invention relates to flue gas desulfurization technique field, more specifically, it relates to the interactive spray system of a kind of fume desulfurating absorption tower.
Background technology
Power plant of China and Industrial Boiler adopt coal to be fuel, in the process of burning, produce SO
2etc. harmful substance, be the SO in removing flue gas
2and meeting the environmental requirement day by day improved, domestic thermal power plant have employed limestone/gypsum wet flue gas desulphurization technology more.
The spray system on absorption tower is the important component part of wet desulfurization system, the existing common spray structure of desulfuration absorbing tower is one-sidedly enter to spray female tubular construction, loop slurry enters the female pipe of spray by the outer slurries pipeline of tower, again by spray female pipe upper isolated each road arm, absorption serum step-by-step is assigned in each nozzle, the netted spraying layer of final formation.This spray structure adopts the one-sided mother of entering to manage, sprayed slurry pipeline in the process of conveying is longer, and caliber changes greatly, there is larger linear loss, cause the uneven of nozzle flow, affect the uniform distribution of spraying layer, reduce spray-absorption efficiency, finally have impact on the desulfurization of whole system except useless effect.One-sided enter to spray female pipe spray system run time, because slurries are distributed into uneven state in pipeline, the load of spray system is caused also to there is problem of non-uniform, the distortion of female pipe self is larger, the inside girder steel hanging or lift installation also result in the concentrated problem of stress, therefore, in absorption tower design and installation process, should be noted that the load assignment problem of spray system, thus improve designing requirement and installation difficulty.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of evenly spraying effect is provided, improves slurries absorption efficiency, balanced pipeline load assignment, in limited space, improve slurries spray flux, finally reach the interactive spray system of the fume desulfurating absorption tower improving desulfuration efficiency object.
The interactive spray system of this fume desulfurating absorption tower, system is parallel to be stratified and set in the body of absorption tower, and every layer comprises many female pipe, nozzle, support steel beam and the bearing compositions of spray; The female pipe of spray is subtend parallel arrangement successively, and the diameter dimension spraying female pipe is reduced to distal step is trapezoidal section by section by near-end, and in pipeline, evenly, each nozzle flow is identical for flow velocity; Spray female pipe through the cover interface tube be welded on the body of absorption tower and outer loop slurry pipe Flange joint, and stretch into absorption tower body, small end is placed on bearing, and centre is fixed on support steel beam by anchor ear; The outer loop slurry pipe of every layer is all connected with perpendicular supervisor.
As preferably: spray female pipe and adopt FRP material, nozzle adopts carbofrax material.
As preferably: nozzle adopts FRP to be intertwined and connected with the connection of the female pipe of spray.
The invention has the beneficial effects as follows:
1. in one deck inner support girder steel, adopt female pipe bilateral to enter, reach the flow of original two-layer spray, improve the liquid-gas ratio of desulphurization system further;
2. the female pipe of interactive spray more traditional one-sided enter the female pipe of spray simple, it is relatively convenient to arrange, and make and process also corresponding simplification, installation work-hour is also shortened.
3. save the female pipe arrangement space of spray, reduce absorption tower height, reduce loop slurry pump lift, reduce desulfurization power consumption;
4. for desulfurization synergistic improvement project, original inner supporting structure can be made full use of, not increase absorption tower height, reduce retrofit work amount, shorten the transformation duration.

Description of reference numerals: absorption tower body 1, cover interface tube 2, sprays female pipe 3, nozzle 4, outer loop slurry pipe 5, bearing 6, support steel beam 7, supervisor 8.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described further.The explanation of following embodiment just understands the present invention for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
Circulate interactive spray system on inventive desulfurization absorption tower, can be stratified and set in absorption tower 1, sprayed slurry is lime stone slurry, is transported to the female pipe of spray and sprays, constantly circulate by circulation slurry pump from bottom slurry district, absorption tower by outer loop slurry pipe 5.Every layer of spraying layer is primarily of the many female pipes of spray, nozzle, support steel beam, bearing compositions.Nozzle 4 and the inner connection spraying female pipe 3 adopt to be wound around and link, and female pipe Size ladder shape is reduced section by section, ensures that each nozzle flow is identical.Spray female pipe 3 through the cover interface tube 2 be welded on absorption tower 1 and outer loop slurry pipe 5 Flange joint, and stretch into absorption tower, small end is placed on bearing 6, and centre is fixed on support steel beam 7 by anchor ear.The outer loop slurry pipe 5 of every layer is all connected with perpendicular supervisor 8.
Spray female pipe 3 and nozzle 4 can adopt unlike material material, to design program calculatings through spray coverage rate, meet the Cover treatment rate requirement of center and circumferential nozzle, avoid washing away tower wall 1, optimization injector configuration;
Spray female pipe 3 and stretch into inside, absorption tower by the interface tube be welded on the body of absorption tower, the other end to be placed on bearing 6, is middlely fixed by anchor ear and support steel beam;
The diameter dimension of the female pipe 3 of inner spray is reduced to distal step is trapezoidal section by section by near-end, ensures that in pipeline, flow velocity is even.The layout that bilateral enters, make each spray female pipe 3 load comparatively even, during operation, self-deformation is less, facilitates the design and installation of spray system.Adopt FRP to be wound around between the female pipe of spray with nozzle to link.
This mutual spray system can multilayer be arranged, individual layer spray flux can reach original two-layer spray flux.Lime stone slurry forms misty liquid droplets by nozzle 4, fully mixes with flue gas from bottom to top, reaches SO in efficient removal flue gas
2object.
As shown in Figure 1, outer loop slurry pipe 5 and the female pipe 3 of inner spray are connected, and the slurries bottom absorption tower in stock tank, to be more evenly sprayed onto in the inner section of absorption tower by the nozzle 4 in spray system in spray system by Cemented filling.
As shown in Figure 2, the support steel beam 7 of inside, absorption tower, will spray female pipe 3 system fixing-stable by alloy anchor ear; The fractional load of spray system is scattered on the tower wall of absorption tower body 1 by cover interface tube 2 and bearing 6 simultaneously.
As a kind of embodiment: every layer of spray system is one-sided has 7 to spray female pipes 3, one deck bilateral has 14 female pipes 3 of spray, sprays female pipe 3 both sides and directly divides delivery nozzle 4.The female pipe 3 of the spray of every one deck be fixed on inner support girder steel 7 by anchor ear, support steel beam 7 is horizontally fixed in absorption tower.Desulfuration efficiency 93% ~ 94.5% before transformation, desulfuration efficiency 98% after transformation.
