Abstract
The utility model discloses a liquid distributor of a tail gas absorbing and packing tower. The liquid distributor comprises a feeding pipe, a distributor bottom plate, a plurality of gas channel pipes and a plurality of liquid overflow pipes. The gas channel pipes and the liquid overflow pipes are arranged on the distributor bottom plate. The gas channel pipes are annularly and uniformly distributed on the distributor bottom plate. The liquid overflow pipes are positioned in a circle encircled by the gas channel pipes. A baffle is arranged between every two adjacent gas channel pipes. The feeding pipe is opposite to the baffle. An overflow channel is reserved between the baffle and the distributor bottom plate. The liquid overflow pipes and the distributor bottom plate are in threaded connection. The gas channel pipes and the through hole of the distributor bottom plate are in inserted connection. Sealing rings are arranged at upper and lower ends of the through hole. The gas channel pipes are 250-350 mm in length. According to the liquid distributor disclosed by the utility model, the liquid distributor has the advantages of uniform liquid spray, one-by-one adjustable liquid overflow pipes and no leakage of tower sections; the stability of a membrane suction system is increased; the absorption of hydrogen chloride is ensured; the consumption of alkaline liquor is reduced; and the steady operation of the device is effectively ensured.
Description
Technical field
The utility model relates to the liquid distribution trough in a kind of tail gas dry load tower, a kind of specifically liquid distribution trough that is used for absorbing hydrogen chloride.
Background technology
Some problem below the liquid distribution trough of present employed tail gas dry load tower exists: 1, liquid phase material receives liquid directly from top fed on distributor liquid phase overflow pipe plane, and to filler, liquid phase is sprayed and can not be uniformly distributed with through the distributor overflow.2, its liquid overflow pipe directly is adhesively fixed on the distributor, is uneven, and liquid phase material maybe be because the error of installation level causes skewness on the distributor, and the bias current phenomenon is serious.To folder, the sealing effectiveness between sparger end plate and the gas tube channel is poor with the big flange of equipment for 3 distributors, and the equipment tower saves frequent seepage.
There is the hydrogen chloride absorption scarce capacity in the liquid distribution trough of this for this reason tail gas dry load tower; The hydrogen chloride that can't be absorbed processing in a large number gets into exhaust treatment system; And tail gas absorption system Design Treatment scarce capacity; Can't absorb a large amount of hydrogen chloride of discharging, cause the hydrogen chloride waste, consume a large amount of alkali lye simultaneously from the film absorption tower.
The utility model content
The purpose of the utility model is defective and the deficiency to above-mentioned prior art, and a kind of liquid phase is sprayed evenly, the height of liquid overflow pipe is adjustable by root for people provide, and tower saves the liquid distribution trough of leak free tail gas dry load tower.
For realizing that the technical scheme that above-mentioned purpose the utility model is taked is: the liquid distribution trough of this tail gas dry load tower comprises feed pipe, sparger end plate and is arranged at many gas passage pipes and the many liquid overflow pipes on the sparger end plate; Gas passage pipe annular on sparger end plate is uniformly distributed with; Liquid overflow pipe is positioned at the circle that the gas passage pipe is surrounded; Between adjacent two gas passage pipes, be provided with baffle plate; Feed pipe and baffle plate are relative, between baffle plate and sparger end plate, leave overflow ducts.
Described liquid overflow pipe and sparger end plate are through being threaded.
The through hole of described gas passage pipe and sparger end plate is pegged graft, and is provided with sealing ring at the upper/lower terminal of through hole.
The length of described gas passage pipe is 250 millimeters to 350 millimeters.
The utility model liquid phase material is after baffle plate stops, evenly overflow is to liquid overflow pipe around the overflow ducts, so liquid phase is sprayed evenly.Because liquid overflow pipe and sparger end plate be through being threaded, thus the height of liquid overflow pipe to pursue root adjustable, be convenient to all liq overflow pipe is adjusted to level.At the sealing ring that the upper/lower terminal of through hole is provided with, the tower joint is not had leak.Therefore this device improves film desorption system stability effectively, guarantees the absorption of hydrogen chloride, reduces the waste of alkali lye, and the stable operation of device is effectively ensured.

The specific embodiment
Like Fig. 1, shown in Figure 2; The utility model is a kind of liquid distribution trough of tail gas dry load tower; It comprises feed pipe 6, sparger end plate 3 and is arranged at many gas passage pipes 1 and the Duo Gen liquid overflow pipe 2 on the sparger end plate 3; Gas passage pipe 1 annular on sparger end plate 3 is uniformly distributed with, and liquid overflow pipe 2 is positioned at the circle that gas passage pipe 1 is surrounded, and between adjacent two gas passage pipes 1, is provided with baffle plate 4; Feed pipe 6 is relative with baffle plate 4, between baffle plate 4 and sparger end plate 3, leaves overflow ducts 5.The liquid phase material that flows into by feed pipe 6 after baffle plate 4 stops, even overflow to liquid overflow pipe 2 around the overflow ducts 5, so liquid phase is sprayed evenly.In order to prevent that liquid phase material from splashing and cross gas passage pipe 1, the length h of gas passage pipe 1 is increased, can be at 250 millimeters to 350 millimeters.
As shown in Figure 3, described liquid overflow pipe 2 is connected through screw thread 7 with sparger end plate 3, so the height of liquid overflow pipe 2 is adjustable by root, is convenient to all liq overflow pipe 2 is adjusted to level.
As shown in Figure 4, the through hole of described gas passage pipe 1 and sparger end plate 3 is pegged graft, and is provided with sealing ring 8 at the upper/lower terminal of through hole, the tower joint is not had leak.
