摘要： A dirt separator for a vacuum cleaner includes a first separation stage having a first dirt collection chamber; a second separation stage downstream of the first, the second separation stage having a second dirt collection chamber; a lid movable between closed and open positions to selectively block and unblock an emptying aperture provided in the first dirt collection chamber; and a latch mechanism. The first and second dirt collection chambers are movable relative to one another. The latch mechanism is configured to secure the dirt collection chambers in a first position, and to secure the lid in the closed position. The latch mechanism is configured to allow the first and second dirt collection chambers to move towards a second position, and to allow the lid to move towards the open position, when the latch mechanism is in the releasing configuration.

摘要： A vacuum cleaning apparatus including a cyclonic separating apparatus having a first cyclonic separator, a second cyclonic separator downstream, a first dirt collector for collecting dirt from the first cyclonic separator comprising an end wall, and a second dirt collector for collecting dirt from the second cyclonic separator comprising an outer wall and at least a portion of the end wall. The first dirt collector and the outer wall of the second dirt collector are movable between a closed configuration in which the end wall abuts the outer wall and an open configuration in which the end wall is spaced from the outer wall for removing dirt from the second collector. The apparatus comprises a detent mechanism for permitting movement of the first dirt collector and the outer wall of the second dirt collector from the closed to the open configurations and to prevent movement into the open configuration.

摘要： A two-stage dust-air separation structure includes a cyclone separator and a spiral dust-air separation device. A first stage separation of dust from air is realized by a cyclone housing, and by arranging a second-stage cyclone barrel 5 inside the cyclone housing and arranging the spiral dust-air separation device at a barrel opening of the second-stage cyclone barrel, the dusty air, after going through the first stage separation, is guided by the spiral dust-air separation device to form, on an inner wall of the second-stage cyclone barrel, an airflow rotating towards the barrel bottom, and the dust in the airflow is driven by a centrifugal force to rotate downwardly to the barrel bottom and be collected in a second-stage dust collecting space, and the air in the rotating airflow is extracted by the negative pressure, thereby realizing a second stage separation of dust from air.

摘要： A dust collector includes a primary cyclone unit to separate dust from air introduced from outside dust collector and a secondary cyclone unit includes axial cyclones which separate fine dust from air introduced in an axial direction. The secondary cyclone unit includes a first group of axial cyclones disposed along a circumference of a first circle so as to contact an inner circumferential surface of an inner case, and formed to be partially spaced apart from the inner circumferential surface of the inner case to form first passages therebetween; and a second group of axial cyclones disposed to contact each other along a circumference of a second circle concentric with the first circle and smaller than the first circle, and formed to contact some of the first group of axial cyclones and to be spaced apart from others of the first group axial cyclones to form second passages therebetween.

摘要： At least one embodiment of the invention relates to a centrifugal/cyclone separator which separates particles, liquid droplets and or condensing mists (water based and or hydrocarbon based nature) from gases without using a filter element. The design relies on the use of the inlet spiral tube, a first conical fin and the second conical fin, and the step on the cylindrical body and the extension of the vortex finder below second conical fin. With another embodiment, the design differs in that it relies on the insert with threaded or open area forming a flow path like spiral tube, while relying on the same or similar components as with the first embodiment listed above.

摘要： An apparatus and process is disclosed for mitigating coking in an FCC reactor plenum. The apparatus and process utilize a baffle to create a inner volume for the product vapors to prevent contact with a relatively cool plenum. The baffle also limits the amount of the time the product vapors spend in the plenum minimizing time for coke formation and limit product vapors from entering low fluidization zones.

The cyclonic separator assembly also includes a cyclone unit positioned within the body between the inlet and the outlet. The cyclone unit has an outer perimeter that is spaced apart from the inner surface of the body to define an inlet space therebetween. The cyclone unit includes a plurality of first cyclones in communication with the inlet space and arranged along an outer circle adjacent the outer perimeter. The cyclone unit also includes a plurality of second cyclones in communication with the inlet space and arranged along an inner circle that is spaced apart from the outer circle such that each second cyclone is nested between two adjacent first cyclones. The plurality of first cyclones and the plurality of second cyclones are arranged in parallel.

摘要： A method for obtaining gypsum using a flue-gas desulfurization system (FGD) having a gypsum suspension, which includes fine materials such as active carbon particles or residual carbonate particles for example, accumulates in the scrubber of a wet flue gas scrubber. The gypsum-containing suspension is thickened by at least one hydrocyclone, and the thickened gypsum suspension is discharged via the underflow of the hydrocyclone. Water is fed to the hydrocyclone in addition to the gypsum suspension via a dedicated feed line such that the content of fine material is thus reduced with respect to the suspension volume in the underflow.
