The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Shown in Figure 1, the utility model comprises: one-level distributor and secondary distributor, wherein the one-level distributor is provided with active carbon bed between one-level distributor and the secondary distributor above the secondary distributor.The secondary distributor is up and down between two active carbon beds.One-level distributor, secondary distributor and active carbon bed are positioned at layering adsorption desulfurize tower.
The one-level distributor is double-deck calandria distributor, comprises the person in charge, two upper strata looped pipelines, two lower floor's looped pipelines, many upper strata liquid distributors, many lower floor's liquid distributors.The person in charge is divided into interior pipe and the outer tube of mutual fit.The upper strata looped pipeline has two, is installed on the person in charge's the left and right sides; The upper strata liquid distributor is installed on the both sides, front and back of upper strata looped pipeline, and between the liquid distributor of adjacent upper strata between left and right every equating; Lower floor's looped pipeline has two, be installed on the person in charge's the left and right sides and be positioned at the upper strata looped pipeline under; Lower floor's liquid distributor is installed on the both sides, front and back of lower floor's looped pipeline, and between the adjacent lower floor liquid distributor between left and right every equating; Upper strata liquid distributor and the projection of lower floor's liquid distributor on horizontal plane are staggered mutually.In pipe be communicated with the lower floor looped pipeline, outer tube is communicated with the upper strata looped pipeline; The upper end of interior pipe is lower than the upper end of outer tube, and is higher than the upper strata looped pipeline.Space, upper strata looped pipeline and Duo Gen upper strata liquid distributor between interior pipe and the outer tube are communicated with successively; Interior pipe, lower floor's looped pipeline and Duo Gen lower floor liquid distributor are communicated with successively.The lower end tube wall of upper strata liquid distributor and lower floor's liquid distributor is provided with perforate vertically downward.Between the liquid distributor of upper strata between left and right every 120 millimeters, between lower floor's liquid distributor between left and right every 120 millimeters; The aperture of perforate is 3 millimeters; Between the perforate on same upper strata liquid distributor or the lower floor's liquid distributor, be spaced apart 50 millimeters.The upper strata liquid distributor joins by screw thread and upper strata looped pipeline, and lower floor's liquid distributor joins by screw thread and lower floor's looped pipeline, thereby upper strata liquid distributor and lower floor's liquid distributor can be installed and removed easily.
The secondary distributor comprises: filler supports the individual layer shell and tube distributor of grid and pressure type, and wherein filler supports grid above individual layer shell and tube distributor.The upper surface that filler supports grid is provided with liquid-droping groove a plurality of sinkings, arrayed, and the bottom of liquid-droping groove has through hole; Individual layer shell and tube distributor comprises many combs (the comb length direction is perpendicular to the paper direction); Comb staggers mutually with the projection of liquid-droping groove on horizontal plane of arranging of embarking on journey.The liquid inlet of individual layer shell and tube distributor is positioned at the sidewall of layering adsorption desulfurize tower, sprays by fluid pressure; Filler supports grid and is installed on the sidewall of layering adsorption desulfurize tower by criss-cross bracing frame.Liquid-droping groove is rectangular channel, and length is 70 millimeters, and width is 20 millimeters, highly is 50 millimeters, and it is 4 millimeters through hole that the bottom has two diameters; Lateral separation between the adjacent liquid-droping groove is 120 millimeters, and fore-and-aft distance is 30 millimeters.The spray flow of individual layer shell and tube distributor is that half of one-level distributor gets final product.
The spray flux of every square metre of active carbon bed of the utility model washing density is 4m
3/ h, one-level distributor and secondary distributor apart from the height of below active carbon bed between 150 millimeters to 200 millimeters, the flow velocity of liquid is 0.3～0.5m/s in the person in charge, upper strata looped pipeline and the lower floor's looped pipeline, flow rate of liquid is 0.2～0.4m/s in upper strata liquid distributor and the lower floor's liquid distributor, and pipeline diameter calculates according to spray flow and velocity in pipes.
During the utility model operation, when liquid entered the interior pipe of one-level distributor, its lower floor's looped pipeline, lower floor's liquid distributor also had liquid to flow into, and the perforate of liquid on lower floor's liquid distributor flowed out automatically, realizes spray.Along with the rising of interior pipe liquid level, the liquid of outflow increases gradually, when liquid level rise to exceed in during the upper end of pipe, excess liquid flows to the space between outer tube and the interior pipe, upper strata looped pipeline, upper strata liquid distributor also have liquid to flow into, and liquid flows out automatically through the perforate of upper strata liquid distributor, realize spray.Upper strata liquid distributor and lower floor's liquid distributor shift to install, and reach the desired sprinkle density of technology.Shown in Fig. 3 sprinkle density schematic diagram, spreading radius with liquid in the activated carbon granule is example for 40 millimeters, the sprinkle density of the double-deck calandria distributor in left side has covered all active carbon beds substantially, and spray can only reach requirement by the sprinkle density between same liquid distributor under the individual layer comb structure of distributor of right side, but has bigger gap between the adjacent liquid distributor, the part active carbon bed is not fully washed, and sprinkle density can't reach requirement.Therefore the one-level distributor adopts the structure of double-deck calandria distributor, can realize the dislocation spray, and spray elasticity is big, can lean on the gravity spray, again can the depended on pressure spray, and sprinkle density is big, can cover active carbon bed fully substantially.
Liquid is flowed through behind the active carbon bed between one-level distributor and the secondary distributor, support the liquid-droping groove inner accumulated of grid at filler, and flow out from the through hole of liquid-droping groove lower end, spray by gravity, can utilize upper strata active carbon bed washings that lower floor's active carbon is reused, and sprinkle density is even relatively.Simultaneously, individual layer shell and tube distributor below realize to replenish spray, guarantee to reach good spray effect.The secondary distributor adopts double-deck spray, and the dislocation spray, can satisfy the density requirements of spray, and the effect of sprinkle density is identical with the spray effect of double-deck calandria distributor among Fig. 3, and secondary structure of distributor compactness, highly only is 130 millimeters; Misconstruction except promoting sprinkle density, also makes the below of filler support grid that enough space mounting bracing frames are arranged up and down.
The utility model is simple in structure, is easy to processing, and structure is tight, reduced the influence of washing regeneration distributor to flue gas flow equalizing, reduced the height between the active carbon bed, and sprinkle density has been big, be evenly distributed, the washing favorable regeneration effect has reduced active carbon washing regeneration required time.
Above-described embodiment is the utility model preferred implementation; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
