Abstract
The utility model discloses an air quantity distributing pipe which comprises a purifying air pipe which is provided with at least two smoke gas treating unit connecting joints which can be connected with smoke gas treating units, a spacer plate is arranged in the purifying air pipe and divides the inner cavity of the purifying air pipe into at least two branch pipes, and smoke gas treating unit connecting joints are respectively communicated with at least one of the branch pipes. The utility model uniformly divides the purifying air pipe into n independent smoke expelling branch pipes which are respectively corresponding to the smoke gas treating units, uniformly distributes the quantity of air flow entering the smoke gas treating units, enhances smoke gas treating efficiency, balances the use rate of the smoke gas treating units, simultaneously reinforces and supports purifying air pipes and branch pipes with larger cross sectional area for preventing the deformation of the air pipe, has the advantages that the utility model has simple structure and can uniformly distribute air flow in a plurality of smoke gas treating units and solves the shortages the existing in prior art.
Description
Technical field:
The utility model relates to a kind of alumina adsorption dry method flue gas purification system that is used for, and can give the air quantity distribution piping of fume treatment unit the air quantity uniformly distributing, belongs to flue gas distribution conveying technology field in the aluminum oxide flue gases purification.
Background technology:
Along with electrolyzer maximization technology rapid development, electrolytic production capacity supporting flue gas purification system also along with increase, the filtration area of supporting bag-type dust equipment also increase thereupon, the filtration area of separate unit fly-ash separator just can not be satisfied the demand, and present dust removal installation all is to be combined by a plurality of fume treatment unit.Electrolyzer flue gas dry cleaning technology is to utilize the Aluminium Electrolysis raw alumina hydrogen fluoride gas to be had the principle of stronger adsorptive power, it is joined in the flue gas smoking gas containing fluorine is carried out dry cleaning, for aluminum oxide is settled down in smoke pipe, gas velocity in the smoke evacuation house steward should remain on about 16～22m/s and (be generally 18～19m/s), because speed is higher, the inertia effect of aluminum oxide in the smoke evacuation house steward, make that to enter the alumina amount of back fume treatment unit unitary more than the front, flue gas can not be assigned to each fume treatment unit uniformly, and aluminum oxide density unevenness in whole dust removal installation just influences the dust-collecting efficiency of sack cleaner; And the alumina concentration height of back fume treatment unit makes the filter bag damage rate of back fume treatment unit also greater than the fume treatment unit of front, has increased workman's maintenance workload.
Summary of the invention:
The purpose of this utility model is: provide a kind of simple in structure, can be uniformly distributed to air quantity distribution piping in a plurality of fume treatment unit to air-flow.
The utility model is to constitute like this: it comprises purification airduct (2), on purification airduct (2), be provided with the fume treatment unit connecting interface (1) that 2 energy are connected with fume treatment unit at least, and in purifying airduct (2), be provided with the dividing plate (3) that the inner chamber that will purify airduct (2) is separated at least 2 arms (4), and each fume treatment unit connecting interface (1) is connected with 1 arm (4) at least respectively; The summation of the section area of the arm (4) that each fume treatment unit connecting interface (1) is connected is identical; Junction at arm (4) and fume treatment unit connecting interface (1) is provided with flow deflector (5); Junction at arm (4) and fume treatment unit connecting interface (1) is provided with inspection port (6).
Owing to adopted such scheme, the utility model is divided into a plurality of arms of independently discharging fume purifying airduct, with entering the airshed evenly distribute of fume treatment unit, has improved the flue gas processing efficiency, and balance the rate of utilization of fume treatment unit.Bigger to cross-sectional area simultaneously purification airduct, dividing plate also rise strengthens supporting role in case the airduct distortion.Therefore the utlity model has simple in structure, can be uniformly distributed to advantage in a plurality of fume treatment unit to air-flow, solved deficiency of the prior art.

Embodiment:
Embodiment of the present utility model: the utility model can be transformed in existing alumina adsorption dry method flue gas purification system, as having 4 fume treatment unit in the flue gas purification system, can will purify airduct (2) with dividing plate (3) earlier and be divided into 2 layers up and down, every layer is provided with 2 fume treatment unit connecting interfaces (1) (as shown in Figure 1), on the upper strata, with vertical dividing plate (3) upper strata is purified airduct (2) and be divided into 3 arms (4) again, the area of middle arm (4) is the area sum of adjacent two arms (4); With middle arm (4) connection 1 fume treatment unit connecting interface (1), again two arms (4) are merged back connection 1 fume treatment unit connecting interface (1) in addition earlier, the arm on upper strata (4) connection finishes; In lower floor, with vertical dividing plate (3) lower floor is purified airduct (2) and be equally divided into 4 arms (4) again, after the upper strata is propped up pipe coupling and is finished, again the purification airduct (2) of lower floor is connected two other fume treatment unit connecting interface (1) according to the method on upper strata, can make the summation of section area of the arm (4) that each fume treatment unit connecting interface (1) connected identical like this; Then at arcual metal sheet of the junction of each arm (4) and fume treatment unit connecting interface (1) welding as flow deflector (5), offer an inspection port again and (6).
Implementation method of the present utility model also can be that purification airduct (2) is equally divided into 4 arms (4) with dividing plate (3), each arm (4) connects a fume treatment unit connecting interface (1), but adopt above-mentioned purification airduct to be divided into multilayer, and the design benefit of a middle pipe coupling fume treatment unit connecting interface is: the airshed evenly distribute that not only will enter fume treatment unit, improved the flue gas processing efficiency, and save the space and the material of airduct, can make vertically neat installation of fume treatment unit, be beneficial to production management.
