Abstract
The invention discloses a red mud desulfurizing tower, which comprises a cylinder body (1); the upper end and the lower end of the cylinder body (1) are provided with a smoke outlet (2) and a red mud outlet (3) respectively; the upper section of the cylinder body (1) is connected with a red mud inlet pipe (4); the lower section of the cylinder body (1) is connected with a smoke inlet pipe (5); and one or more upper convex tower trays (6) and lower concave tower trays (7) are alternately arranged in the cylinder body (1). The upper convex tower trays (6) and lower concave tower trays (7) are utilized to make falling red mud alternately have the moving process of flowing from the middle to the periphery or from the periphery to the middle in the tower trays, the red mud is contacted with upward smoke more fully, the absorption degree of smoke gas is higher, and the red mud desulfurizing tower has the advantages of uniform distribution of the red mud, good fluidity, convenient equipment overhauling and maintenance, and the like.
Description
Technical field:
The present invention relates to a kind of desulfurizing tower, particularly a kind of red mud desulfurizing tower.
Background technology:
Because of the discarded red mud in the up-to-date detection alumina producing has good suction-operated to sulfur dioxide gas, and have the high advantage such as effective of absorption efficiency, also reach the discharge standard of national requirements for environmental protection according to its adsorption effect of laboratory tests data fully.Therefore just there is the problem that how lab scale equipment is converted into large-scale production equipment; If directly use existing desulfurizing tower; Then can receive the excessive restriction of red mud water content, can exist the red mud cloth inhomogeneous, mobile bad, overhaul of the equipments, safeguard problem such as inconvenience.
Summary of the invention
The technical problem that the present invention will solve is: provide a kind of discarded red mud is fully contacted with flue gas, and the red mud cloth is even, good fluidity, overhaul of the equipments, red mud desulfurizing tower easy to maintenance can overcome the deficiency of prior art.
The technical scheme that the present invention takes is: it comprises cylindrical shell, is respectively equipped with the outlet of exhanst gas outlet and red mud in the top and bottom of cylindrical shell, is connected with the red mud inlet tube at the epimere of cylindrical shell, is connected with flue gas inlet tube at the hypomere of cylindrical shell; In cylindrical shell, be provided with epirelief tower tray and recessed tower tray more than 1 or 1, and the epirelief tower tray more than 1 or 1 and recessed tower tray are installed in the cylindrical shell alternately.
The main body of epirelief tower tray is the disk that raises up, and the awl cap that centrum makes progress is installed in the center of disk, on disk, offers plural strip hole, and on disk, is welded with deflector.
The main body of recessed tower tray is the disk to lower recess, offers circular hole in the center of disk, on circular hole, is connected with the downward awl cap of centrum, and on disk, offers plural airflow hole, and on disk, be welded with deflector.
Lower end at cylindrical shell is connected with skirt.
On cylindrical shell, be connected with operating desk.
On cylindrical shell, be provided with eyepiece.
The port of export of red mud inlet tube is positioned at the center of cylindrical shell.
Prior art is compared, and the present invention connects the red mud inlet tube through the epimere at cylindrical shell, at the hypomere connection flue gas inlet tube of cylindrical shell; And epirelief tower tray and recessed tower tray more than 1 or 1 are set in cylindrical shell; Epirelief tower tray and recessed tower tray more than one or one alternately are installed in the cylindrical shell.The red mud that such setting causes to fall and break with regard to epirelief tower tray capable of using and recessed tower tray on tower tray, alternately occur from the centre to around flow or all around to the motion process of intermediate flow; Make red mud more abundant with contacting of the flue gas that makes progress, the smoke absorption degree is bigger.The main body of epirelief tower tray is the disk that raises up, and the awl cap that centrum makes progress is installed in the center of disk, on disk, offers plural strip hole, on disk, is welded with deflector.The main body of recessed tower tray is the disk to lower recess, offers circular hole in the center of disk, on circular hole, is connected with the downward awl cap of centrum, and on disk, offers plural airflow hole, on disk, is welded with deflector; The epirelief tower tray and the recessed tower tray that are provided with like this can make the red mud cloth more even, and be mobile better; Lower end at cylindrical shell is connected with skirt, can be convenient to installation of the present invention like this; On cylindrical shell, be provided with operating desk, like this can be so that change, keep in repair epirelief tower tray and recessed tower tray through the manhole on the cylindrical shell.On cylindrical shell, be provided with eyepiece, can be used for seeing Cha Tanei red mud cloth film situation like this; The port of export of red mud inlet tube is positioned at the center of cylindrical shell; So better cloth.
Description of drawings
Fig. 1 is the structural representation of invention.
The specific embodiment
Embodiments of the invention: as shown in Figure 1, cylindrical shell 1 forms by the joint assembly welding after by the steel plate reel, when making cylindrical shell 1; The epirelief tower tray 6 that in cylindrical shell 1, welds or be connected with more than 1 or 1 alternately is installed in the cylindrical shell 1 with recessed tower tray 7 with the epirelief tower tray 6 of recessed tower tray more than 7,1 or 1, and wherein the main body of epirelief tower tray 6 is the disk that raises up; Disk strikes weldering system by steel plate; Weld the awl cap that centrum makes progress in the center of disk after making disk, and on disk, cut out plural strip hole, even for making cloth; The strip hole is distributed on the disk; Divergent shape in mostly being around the mind-set is welded with deflector simultaneously on disk, can prevent that like this red mud from piling up to same point.The main body of recessed tower tray 7 is the disk to lower recess, and disk strikes weldering system by steel plate, makes behind the disk and to open a circular hole in the center of disk; Awl cap that centrum is downward of welding on circular hole; And on disk, offer plural circular airflow hole, even for making cloth, circular port is distributed on the disk; Mostly be the divergent shape around the middle mind-set, on disk, be welded with deflector simultaneously.After making cylindrical shell 1; Offer exhanst gas outlet 2 and red mud outlet 3 respectively in the top and bottom of cylindrical shell 1; Simultaneously the epimere at cylindrical shell 1 connects a red mud inlet tube 4, and the port of export of red mud inlet tube 4 is positioned at the center of cylindrical shell 1, is connected with flue gas inlet tube 5 at the hypomere of cylindrical shell 1; When cylindrical shell 1 is erected, connect skirt 8 in the lower end of cylindrical shell 1.For the convenient cloth situation of observing is connected with operating desk 9, manhole and eyepiece 10 with being maintained on the cylindrical shell 1.
The concrete course of work does; Red mud is through the central upper portion position blanking of red mud inlet tube 4 from cylindrical shell 1; The red mud that falls from the center is dispersed on the disk of epirelief tower tray 6 to periphery through the awl cap of first floor epirelief tower tray 6, and evenly branches to epirelief tower tray 6 everywhere along deflector, is dropped by the strip hole; Flue gas also overflows along the strip hole simultaneously, makes red mud and flue gas in convection process, realize mass transfer.The red mud that falls flow to the card of recessed tower tray 7; And the recessed conical flow of the recessed tower tray 7 in edge is to the center hole place; Circular airflow hole on the recessed tower tray 7 is an exhaust gases passes; Drop on red mud on the recessed tower tray 7 and be tiled in and form membranaceously on the recessed tower tray 7, flue gas overflows through the bubbling that makes progress of the circular airflow hole on the recessed tower tray 7, and red mud is fully contacted with flue gas.Epirelief tower tray 6 and recessed tower tray 7 that multilayer is alternately installed each other just can repeatedly repeat said process, finally make the flue gas of discharge reach discharging standards.
