Abstract
The invention discloses a kind of sack cleaner drainage dispersion nozzles, including retainer plate（1）, flow diverter（2）, connector（3）, disperser（4）, described flow diverter（2）Pass through retainer plate（1）It is fixed on injection tube（5）On；Described disperser（4）Pass through connector（3）It is connected with supersonic speed flow diverter, pulse gas enters flow diverter from injection tube, drains ambient gas and by being sprayed after disperser rectification.The present invention improves the injection tolerance of deduster soot cleaning system using flow diverter drainage, carries out rectification to pulse jet air-flow using disperser, makes deashing air-flow more uniform, improve cleaning efficiency, eliminate cloth bag exhaustion phase, improve dust removing effects.
Description
Technical field
Patent of the present invention is related to a kind of sack cleaner drainage dispersion nozzles, belongs to dust removal by ventilation field.
Background technology
Pulse blowing bag type dust precipitator is a kind of high-effective dust-removing cleaning equipment, with ash-removal effect is good, purification efficiency is high, most
I traps the dust of 0.1 microns, and processing is large-minded, life-span of the filter bag is long, maintenance load is small, safe and reliable to operation
The advantages that.
In bag-type dust removing system the quality of soot cleaning system be directly connected to deduster can efficiently, safety, economical operation.Mesh
Before, the purge mode of sack cleaner mainly has gas rotary counter-blowing, machine to shake, gas pulses etc. are several.
Gas pulses are a kind of common purge modes in sack cleaner.Engineering gas pulses deashing skill in practice at present
Art, which also exists, much to be required study and solves the problems, such as.Some presence ash-removal effects are bad, and resistance of the filter bag is big；Some deashing intensity
It is excessive, damage filter bag；Some deashing intensity is irregular, the failure of part cloth bag, not only influences ash-removal effect, and increase cloth bag
Resistance etc..So the quality of deashing is directly connected to the power of regeneration of filtrate.It is that sack cleaner ash-clearing technology is to remove
The deciding factor and key technology of dirt device performance.Existing deduster enters horizontal pulse using plain nozzle or supersonic speed induction nozzle
Deashing, this frequently can lead to, and pulse dust cleaning air-flow is uneven to lateral wall pressure peak value caused by cloth bag, cloth bag itself formation is reverse
Acceleration cloth bag axial direction skewness, influence ash-removal effect, cause filter bag partial failure.
The content of the invention
Lateral wall pressure peak value caused by the cloth bag faced based on pulse dust cleaning technology is uneven, cloth bag itself is formed and reversely added
Speed is the skewness of cloth bag axial direction the problems such as, method that the design is combined using drainage and disperse phase, using drawing at a high speed
Stream increases blowing gas amount while uses disperser（Porous media, porous plate）Disperse is carried out Deng by air-flow, there is provided a kind of pocket type
Deduster drainage dispersion nozzles.
The present invention is to be achieved through the following technical solutions：A kind of sack cleaner drainage dispersion nozzles, it is characterised in that
Including retainer plate, flow diverter, connector, disperser, described flow diverter is fixed in injection tube by retainer plate.
Described flow diverter adds persuader to form by superonic flow nozzzle or conventional nozzle；Described connector construction form is
Internal thread, buckle；Described disperser is shaped as conulite, solid centrum, cylinder；Described disperser material is porous
Plate, porous media；Described disperser is located at immediately below flow diverter, and is connected by connector.
It is of the invention to be relative to the beneficial effect of existing technology：The present invention on the basis of conventional gas pulse dust cleaning,
Applied fluid mechanics correlation theory, the method combined using drainage and disperse phase, increase blowing gas amount is drained at a high speed and is adopted simultaneously
Use disperser（Porous media, porous plate）Disperse is carried out Deng by air-flow, makes pulse dust cleaning air-flow to lateral wall pressure caused by cloth bag
Uniformly, cloth bag itself forms backward acceleration being evenly distributed in cloth bag axial direction, improves cleaning efficiency, eliminates cloth bag exhaustion phase,
Improve dust removing effects.
Brief description of the drawings
Fig. 1 is a kind of sack cleaner drainage dispersion nozzles schematic diagram.In figure：1st, retainer plate, 2, flow diverter, 3, connection
Device, 4, disperser, 5, injection tube.
Embodiment
The present invention is further described below with reference to specific embodiment.As shown in figure 1, a kind of sack cleaner is with drawing
Dispersion nozzles are flowed, in injection tube 5, including retainer plate 1, flow diverter 2, connector 3, disperser 4, described flow diverter 2
It is fixed on by retainer plate 1 in injection tube 5, described flow diverter 2 adds persuader to form by superonic flow nozzzle or conventional nozzle, institute
The structure type of connector 3 stated is internal thread, buckle, and described disperser 4 is shaped as conulite, solid centrum, cylinder,
The described material of disperser 4 is porous plate, porous media, and described disperser 4 is located at immediately below flow diverter 2, and passes through connection
Device 3 is connected.
When sack-duster pulse soot cleaning system is run, high speed injection air-flow enters drainage disperse by injection tube and sprayed
Mouth, by flow diverter to surrounding flow secondary drainage, increase enters disperser progress rectification, the gas after rectification after being blown tolerance
Implement deashing operation into deduster.
Schematically the present invention and embodiments thereof are described above, this describes no restricted, institute in accompanying drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited thereto.So if common skill of this area
Art personnel are enlightened by it, without departing from the spirit of the invention, without designing and the technical scheme for creativeness
Similar frame mode and embodiment, protection scope of the present invention all should be belonged to.
