Description

The horizontal cyclone device

The utility model relates to a kind of horizontal cyclone device, is installed in such as on the equipment of all need to the waste gas dedusting of sintering machine such as iron company's sintering plant, is used for the head of sintering machine, the waste gas dedusting of tail.

At present, the waste gas dedusting equipment of sintering machine mostly is centicell unit greatly, and it is gathered the cyclone group who constitutes by several cyclones (a common cover cleaner is placed with 36 cyclones that do not wait to 1100 quantity according to different sizes).This centicell unit generally can be divided into two kinds of filler and no fillers, the employed cyclone of material filling type multi-tube dust cleaner is wherein arranged, all will place the guider and the wireway weldering of whirlwind (cyclone urceolus) cavity volume upper end to be one without any exception, thereby give the maintenance and the maintenance of whirlwind and clear up grey trowel used for plastering and bring great trouble, and because the structure existing problems of whirlwind self, cause whirlwind filledly just to be achieved on the bottom plate that stably places deduster, so not only cause the increase of a whole set of cleaner weight, and be difficult to guarantee the concentricity with wireway; And China Patent No. is 98226235,3, name is called the patent of " cyclone ", it discloses a kind of employed cyclone in the no material filling type multi-tube dust cleaner that is applicable to, such cyclone, although overcome the defective of above-mentioned cyclone structure, have the maintenance of shortening, maintenance, replacing, cleaning cycle, reduce difficulty of processing, need not in addition with advantages such as fillers, but this one-level formula cleaner is for the dedusting of the higher sintering device handpiece of inlet concentration, tail, and the dust concentration of its discharging is difficult to reach the new standard of national regulation.If adopt the two-stage dust removal of centicell unit and inertial dust separator combination, also be difficult to qualified discharge.If add a lot of plate washers for qualified discharge in inertial dust separator, then " drag losses " increases again, can't adapt to the requirement of sintering process.

The purpose of this utility model be to provide a kind of rational in infrastructure, need not filler, in light weight, install maintenance convenient, can with no material filling type multi-tube dust cleaner be combined into the two-stage dust removal unit, good dedusting effect, horizontal cyclone device that drag losses is little.

The purpose of this utility model is achieved like this, a kind of horizontal cyclone device, comprise: whirlwind 4 of the sub-through hole 3 of a tool whirlwind, one in whirlwind 4 and the guider 1 of the some helical blades 2 of tool, one end of one tool air duct through hole 13 and the air duct 9 described air ducts 9 that communicate with the sub-through hole 3 of whirlwind is installed on the rearing-box plate 6 of cyclone casing 10, the other end inserts in the sub-through hole 3 of whirlwind of whirlwind 4 one ends, the other end of whirlwind 4 is fixing with the preceding boxboard 5 of cyclone casing 10 by the boss on it 12, and guider 1 is installed in the aperture of the sub-through hole 3 of whirlwind of whirlwind 4 other ends.

Below in conjunction with accompanying drawing the utility model is further described below.

Accompanying drawing is the assembly structure figure of the forward and backward boxboard 5,6 of the utility model and cyclone casing 10.

The aperture of the sub-through hole 3 of whirlwind of the utility model whirlwind 4 should be greater than the aperture of air duct 9.Like this when an end of air duct 9 inserts in the sub-through hole 3 of whirlwind of whirlwind 4 one ends, whirlwind 4 and air duct 9 just form the cavity of an annular between the two, are the air outlet 8 of soot emissions.

Helical blade 2 of the present utility model has multi-disc, and helical blade 2 is done with the main body one casting of guider 1.Guider 1 is installed in the aperture of the sub-through hole 3 of whirlwind of close boss 12 1 ends of whirlwind 4, and guider 1 can fix by the convex shoulder in screw and the sub-through hole 3 of whirlwind.When in the aperture that guider 1 is placed the sub-through hole 3 of whirlwind, the vane end faces 14 of each helical blade 2 cooperates with the hole wall of the sub-through hole 3 of whirlwind, dusty gas just can only enter from the surface of helical blade 2, and then the sub-through hole 3 of the whirlwind that enters whirlwind 4 in the shape of a spiral shape, and rotate, make dust sedimentation in whirlwind 4, because the aperture of the sub-through hole 3 of whirlwind is greater than the aperture of air duct 9, thereby dust is just outwards dished out by air outlet 8 along barrel, at this moment since between cyclone casing 10 and the flue-dust retainer 11 for being tightly connected, thereby be negative pressure in the casing, dust granule falls naturally and then enters in the flue-dust retainer 11 of cyclone casing 10 by its deadweight, and purified gas is then drawn by the air duct through hole 13 of air duct 9 and entered and carry out two-stage dust removal in the centicell unit.

The utility model is to be installed on like this on the forward and backward boxboard 5,6 of cyclone casing 10, at first, in the tube chamber 7 before whirlwind 4 is inserted on the boxboard 5, and an end of whirlwind 4 is fixed by boss 12 usefulness screws on it and preceding boxboard 5.Again guider 1 is placed whirlwind 4 by in the sub-through hole 3 of whirlwind of boss 12 1 ends, reach with whirlwind 4 and match.One end of air duct 9 is inserted in the tube chamber 15 of rearing-box plate 6, the other end inserts in the sub-through hole 3 of whirlwind of whirlwind 4 one ends.Come by dozens of, up to a hundred and even thousands of the utility model cyclone because a cover cleaner requires according to difference integrated, so in the above described manner each horizontal cyclone device is installed with mutually with the forward and backward boxboard 5,6 of cyclone casing 10.

The utility model is to come work like this, at first by the fan action of cleaner, a dusty gas just side of the past boxboard 5 enters, through the helical blade 2 of the guider 1 of each horizontal cyclone device, enter then in each whirlwind 4 and rotate, ash fall is got off until being discharged by air outlet 8, and by dust deadweight landing downwards and enter in the flue-dust retainer 11, dust is discharged, and purified gas is then drawn through air duct 9, enters to carry out two-stage dust removal in the centicell unit.Because a cover cleaner need be made of several the utility model horizontal cyclone devices, thereby after using a period of time, when to whirlwind 4 of all cyclones be overhauled, when clearing up, as long as guider 1 and whirlwind 4 are all pulled out, make the maintenance personal clear up or change whole whirlwind 4, install again then and get final product whirlwind 4; When will be,, keep in repair and reload again after finishing as long as pull out the guider 1 and whirlwind 4 of corresponding site to being arranged in 4 maintenances of one or several whirlwind, the cleaning among the cyclone group on the cleaner or when changing.

The utility model is because after adopting said structure, have simple in structure, need not that filler, in light weight, installation and maintenance are convenient, characteristics such as " drag losses " less, after the supporting use of centicell unit, its fine dust efficiency of dust collection reaches 97.5%, total " drag losses " meets the sintering process requirement, relatively is applicable to the higher sintering device handpiece of inlet concentration, tail dedusting; And the efficiency of dust collection long-term stability, the fan rotor life-span also prolongs greatly.
