Description

(54) SEPARATOR

one

The invention relates to devices for extracting powdered materials from a gas stream and can iaiti. Use in the industry of building materials, chemicals, etc., where the processing of powdered materials is carried out.

For the separation of gaseous and solid phases in various industries, cyclones (for coarse cleaning) and bag filters (for fine cleaning) are widely used both as independent apparatuses and in their combination in a common housing.

Separators are known in which bag filters are mounted inside the exhaust pipe of the cyclone RZ and 2

However, this arrangement reduces the efficiency of the cyclone due to an increase in its diameter and increases the load on the filters, which leads to K / them quickly failing. In addition, this arrangement complicates the maintenance of the filters.

A separator is known, comprising a housing, a cyclone placed in it with a dust discharge opening, filter elements with devices for their regeneration, located around

cyclone and together with its exhaust. Noah pipe with flue gas dampers, and dust collector SzZ.

However, this separator is a batch apparatus and is designed to operate with a small load on the solid phase. The solid phase, separated in the cyclone and filters of the indicated cyclone, is collected in the compartments and removed periodically as it accumulates, after the container has been opened.

The purpose of the invention is to ensure the efficiency of the separator at

15 heavy loads on the solid phase.

The goal is achieved by the fact that the separator is equipped with an intermediate chamber covering the cyclone and a moving pipe in the vertical direction,

20 placed in a hole made in the lower part of the dust collector coaxially under the dust exhaust hole of the cyclone, and the ducts are connected to the lower part of the intermediate X1 measure.

30 into an intermediate chamber 3, its lower part connected to gas ducts 4 connecting the intermediate chamber with bag filters 5 located around the cyclone. On the arms b attached to the intermediate chamber, there are mounted shaking electrovibrators 7 (one for each filter pack), designed to regenerate the filters. Gas coolers are equipped with butterfly valves 8 controlled electromagnets (not shown). The intermediate chamber 3 in its lower part has a conical dust collector 9 provided with a movable: pipe 10, the lower end entering the gate 11. The entire apparatus is mounted on the plate 12 and is enclosed in the case 13 with the cover 14, which are the common housing for the cyclone and bag filter. The conical dust collector 9 ends with a fitting 15 having a vertical slot, which includes a pin 16 belonging to the movable nozzle 10. A nut 17 fastened to the threaded part of the nozzle 10, fastened to the helm 18 and limited from axial movement by the ring 19 .. The separator works as follows. Air carrying a ceramic powder shock (or another gas with another powdered material) is fed through pipe 2 into cyclone 1. Here the air on the walls leaves a large part, the largest fraction of powder, which is poured into the dust discharge hole. The small fraction is carried by air into the cyclone exhaust orifice and through intermediate chamber 3 and ducts 4 enters bag filters 5. Solids are trapped by the filter cloth, and air, mine, leaves the machine through the lid 14. Periodically, as the fabric is clogged filter, one of the dampers 8 of the ducts 4 is blocked (in the drawing, the right duct is blocked) and the corresponding electric vibrator 7 is turned on to shake the bag package. When this crumbling parts 1 # 1 are assembled on the shutter 8. When the shaking is completed, the shutter opens and the particles are poured into a conical collector 9, where they are held at the discharge opening by a movable nozzle in the upper (working) position. The nozzle 10, which is in the upper position, delaying the particles that have melted from the filters, opens the cyclone discharge opening, which is necessary for its continuous operation, and at the same time prevents the flow of the separated flow through this opening directly into the filter gas ducts. When one of the bags of bag filters is in the shaking mode, the others are in the normal operating mode of filtration. The shaking mode packets are turned on alternately. If the material from the cyclone can be discharged both periodically and continuously (with a rotary feed gate) j Then the matter from the filters can be discharged only periodically (for example, at the end of a shift). For this, the movable nozzle 10 is lowered to its lowest position, and the material from the filters gets access to the opening in the nozzle. The movement of the nozzle 10 is achieved as follows. At. rotation of the handwheel 18, the nozzle 10 moves in a vertical direction without rotation, slipping the pin 16 through the slot of the fitting 15. Continuous removal of most of the material (98%) caught by the cyclone ensures efficient operation of the proposed separator even with large loads on the solid phase. Claims of the invention A separator comprising a housing, a cyclone disposed therein with a discharge port, filtering elements with devices for regenerating them, located around the cyclone and communicating with its exhaust pipes with gas ducts and dampers, in order to ensure efficient operation of the separator at high loads in the solid phase, it is equipped with an intermediate chamber covering a cyclone, a vertically movable pipe placed in the father, a duel made in the lower part and the dust collector coaxially under the dust outlet of the cyclone, and the ducts are connected to the lower part of the intermediate chamber.
