Abstract

The utility model provides a composite separation duster, and namely, the upper part of the center of an ordinary cyclone separator is provided with a metal-net-type filter. The top of the filter is provided with a pneumatic back-blowing and a vibration device. The composite separation duster is especially suitable for metallurgy or other industrial production to clear various dust and impurity in a high temperature vessel or a mould. The utility model has the advantages of simple and compact structure, low cost, easy maintenance and good dust removing effect. If the utility model is matched with a proper fan, the composite separation duster can replace an industrial duster to use in an environment with larger dust content and plays a role for separating and dust removing at the same time.

Description

Composite separation duster

The utility model relate to a kind of from gas the separation deduster of separating solids grit, be particularly suitable in metallurgy or other industrial production, be used for removing in the elevated temperature vessel or the various dust in the mould and the combined type of impurity are separated dust arrester.

Existing various separator or cyclone dust collectors successfully are applied in the air-transport system of grain processing and various solid particles, or are used for general dust arrester.Only depend on the grit that rotates at a high speed with gas to realize that under centrifugal force and action of inertia sedimentation, its separative efficiency are subjected to air velocity and dust grain bigger through the influence of, severe because of its centrifugation.Therefore, for grain warp and the bigger solid grit of severe excursion, separating effect is often very unstable.Conventional dust collection method also has sack cleaner and various wet scrubber, generally is not suitable for using in the long-pending amount of the dirt environment bigger, high-temperature dust.And wet scrubber has the shortcoming that needs a large amount of water and discharge mud.The occasion that in metallurgical industry is produced, needs dedusting, not only the long-pending amount of dirt is bigger, and temperature is higher, and using conventional cleaner is to be difficult to realize.

The purpose of this utility model is to overcome the weak point of above-mentioned separator and deduster, a kind of bigger solid grit of dustiness that separates from the high-temperature gas mixture body is provided, good dedusting effect, simple and compact for structure, cost is low, easy care can replace the combined type of general industry dust catcher to separate deduster.

The utility model combined type separation deduster is achieved in that the central upper at common cyclone separator, a metal mesh type filter is installed, at the top of its filter strength blowback wind and vibrating device are housed, elastic sealing gasket are housed at cyclone separator and metal mesh type filter junction.The outer cylinder body top of cyclone separator is cylindrical shape, and the bottom is conical, and its lower end is communicated with disposal box, and the below of disposal box is connected with the ash-valve flange.On cyclone separator cylinder top, tangentially have the dusty gas import, be connected with the metal hose of band suction nozzle; And have purified gas outlet on metal mesh type filter top, be connected with the dedusting fan inlet.Its operation principle is: the metal hose that will have suction nozzle inserts to be treated in the elevated temperature vessel or mould of dedusting, start the mist that dedusting fan will suck dust-laden, from separator outer cylinder body top, tangentially enter in the separator, between the annular gap of inside and outside tube, do the high-speed screw motion from top to bottom, because the effect of centrifugal force and inertia force, most of grit is fallen in the disposal box of separator bottom, finishes the first separation udst separation.The gas that contains a small amount of fine dust under the effect of dedusting fan draft, moves upward along the separator center, and during through the metal mesh type filter, dust is stopped by filter screen or is adsorbed on the filter screen, or drops in the disposal box.Gas through the well strainer double purification is discharged through dedusting fan by separating the deduster outlet at last.

When separating deduster after work a period of time, adsorbed more dust on the filter screen, the efficient of separating dedusting will be affected, at this moment start strength blowback wind and vibrating device, blow off or shake and fall in the disposal box being adsorbed on dust on the filter screen, regularly open ash-valve, emit laying dust, can realize that separating deduster works continuously for a long time, overcome the shortcoming of well strainer dismounting deashing commonly used.

The utility model has the advantages that:

1. be used for removing in the elevated temperature vessel effectively or mould dust and impurity, it is big and discharge the difficulty of mud to have overcome the wet scrubber water consumption.

2. simple and compact for structure, be easy to make, use flexibly, easy to maintenance, good dedusting effect.If the suitable blower fan of adapted can replace industrial dust collector to use in the bigger environment of dustiness, play simultaneously and separate and the dedusting effect.

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

The accompanying drawing combined type is separated the deduster structural representation.

As shown in drawings, in cyclone separator central upper inner barrel ［ 4 ］, a metal mesh type filter ［ 8 ］ is installed, and strength blowback wind and vibrating device ［ 1 ］ is housed, elastic sealing gasket ［ 2 ］ is housed at cyclone separator and metal mesh type filter junction in its filter top.The metal hose insertion of band suction nozzle is treated in the elevated temperature vessel or mould of dedusting, start blower fan, to suck the mist of dust-laden through gas feed ［ 3 ］, from separating deduster outer cylinder body ［ 9 ］ top, tangentially entering the separation deduster, between the annular gap of inner barrel ［ 4 ］ and outer cylinder body ［ 9 ］, from top to bottom do the high-speed screw motion, under the effect of centrifugal force and inertia force, most of grit is fallen and is separated in the disposal box ［ 5 ］ that the deduster bottom links to each other with cone, has finished the first separation udst separation.Because the draft effect of dedusting fan, the gas that contains a small amount of fine dust moves upward along the separator center, through the gas that well strainer ［ 8 ］ final dusting purifies, discharges through dedusting fan by separating deduster outlet ［ 7 ］ at last.The mist that contains fine dust is during by filter screen, and certain grain stops by filter screen through the dust of above (the mesh specification by filter screen is decided), or is adsorbed on the filter screen, or drops in the disposal box.When separating deduster after work a period of time, adsorbed more dust on the filter screen, stopped up mesh, the efficient of separating dedusting like this will be affected.At this moment start the strength blowback wind and the vibrating device ［ 1 ］ that are contained in the separation dust remover roof, the dust that is adsorbed on the filter screen is blown off or shakes and fall in the disposal box.Regularly open the ash-valve ［ 6 ］ of disposal box below, emit laying dust, can realize that separating deduster works continuously for a long time.
