Background technology
The absorption tower be a kind of with physics or chemical method with the SO in the flue gas
2Device or the structures removed Deng pernicious gas.In multiple desulfuration absorbing tower; It is the fountain absorption tower that one type of absorption tower is arranged; The groundwork process on fountain absorption tower is to utilize slurry circulating pump will absorb slurries to be transported to the spraying layer that is made up of a plurality of nozzles; Form intensive atomization slurry spray district after absorbing the atomizer ejection of slurries by spraying layer, slurries contact with flue gas in the atomizing spray district, absorb the SO in the flue gas
2Deng pernicious gas, accomplish flue gas desulfurization, slurries descend slowly and lightly in the stock tank of bottom, absorption tower along inside, absorption tower.
One of factor that at present influences fountain absorption tower desulfurized effect is inner flue gas bias current: owing to the reason of spraying layer pipeline and arrangement of nozzles; Cause spraying layer slurries injection density inhomogeneous; And then cause Resistance Distribution inhomogeneous; The regional flue gas flow rate that flue gas resistance is little is fast, produces the flue gas bias current, influences desulfurized effect; The 2nd, the smoke absorption tower side wall is escaped stream: the spraying layer sprinkle density pressing close to the absorption tower sidewall is low; It is less to press close to the resistance that near the flue gas of absorption tower sidewall receives; Cause the fast phenomenon of flue gas flow rate of absorption tower sidewall, sidewall is escaped stream and is also had a strong impact on desulfurized effect.
SO in the existing absorption flue gas of fountain absorption tower slurries between smoke inlet and spraying layer
2In the slurries district that directly descends slowly and lightly after the pernicious gas into absorption tower bottom, can not the slurries that inside, fountain absorption tower descends slowly and lightly be compiled before falling into the slurries district and be used.
Summary of the invention
The purpose of the utility model provide a kind of can solve the inner flue gas bias current in fountain absorption tower and sidewall escape flow phenomenon, desulfurized effect better, the spray type desulphurization absorption tower slurries catch tray that can the slurries that inside, fountain absorption tower descends slowly and lightly be compiled.
The technical solution of the utility model is: it comprises some slurries catch tray orifice plate; Each slurries catch tray orifice plate is respectively the plate body that is provided with a plurality of smoke ventilators between the upper and lower plates face; Each slurries catch tray orifice plate pieces together tabular level mutually and is installed in and is used to be uniformly distributed with the inner flue gas in absorption tower in the spray type desulphurization absorption tower between the foot spraying layer and smoke inlet, solves the flue gas bias current and sidewall is escaped stream, is provided with the gap of the downward slurries that trickle naturally between the part slurries catch tray orifice plate.
The technique effect of the utility model is: the loose structure of desulfuration absorbing tower slurries catch tray can be uniformly distributed with the inner flue gas in absorption tower; Desulfurized effect is better; Can solve inner flue gas bias current in fountain absorption tower and sidewall and escape flow phenomenon, can the slurries that inside, fountain absorption tower descends slowly and lightly be collected and its effective utilization.Use it can reduce the absorption tower liquid-gas ratio, reduce the slurry circulating pump energy consumption significantly.
Description of drawings
Fig. 1 installs stereochemical structure office for the utility model embodiment slurries catch tray and cuts open figure;
Fig. 2 is the utility model embodiment slurries catch tray orifice plate three-dimensional structure diagram.
The specific embodiment
Like Fig. 1, shown in Figure 2; It comprises some slurries catch tray orifice plate 1; Each slurries catch tray orifice plate 1 is respectively the plate body that is provided with a plurality of smoke ventilators 11 between the upper and lower plates face; Each slurries catch tray orifice plate 1 pieces together tabular level mutually and is installed in and is used to be uniformly distributed with the inner flue gas in absorption tower in the spray type desulphurization absorption tower between the foot spraying layer and smoke inlet, solves the flue gas bias current and sidewall is escaped stream, is provided with the gap 2 of the downward slurries that trickle naturally between the part slurries catch tray orifice plate 1.
The slurries that each slurries catch tray orifice plate 1 is collected are trickled to the slurries feeder of slurries catch tray below by gap 2 naturally, thereby realize the slurries collection.
The limit portion of each slurries catch tray orifice plate 1 is provided with the tenon 12 and groove 13 of the splicing that matches respectively.Be respectively equipped with some roads reinforcement 14 on the lower face of each slurries catch tray orifice plate 1.Each slurries catch tray orifice plate 1 limit portion is respectively equipped with perpendicular to the plate face and is used for it is installed in bolt hole 15 and the adjustment bolt hole 16 of the setting height(from bottom) of adjustment slurries catch tray orifice plate 1 on brace summer or the slurries feeder.The limit portion of each slurries catch tray orifice plate 1 is provided with perpendicular to each slurries catch tray orifice plate 1 plate body respectively and projects upwards in the retaining weir plate 17 of slurries catch tray orifice plate 1 upper face, decision slurry layer thickness.Be respectively equipped with on the retaining weir plate 17 of each slurries catch tray orifice plate 1 and be used for each slurries catch tray orifice plate 1 interconnective bolt hole 18.Each slurries catch tray orifice plate 1 is installed on the brace summer or slurries feeder of its underpart through the alloy bolt respectively, between each slurries catch tray orifice plate 1 through tenon 12, groove 13 be installed in the alloy bolt of retaining between the weir plate 17 and interconnect.
