Description

A kind of pipeline pre-dedusting device

Technical field

The utility model relates to a kind of pipeline pre-dedusting device, belongs to the dust arrester installation technical field.

Background technology

Continuous maturation along with the environmental protection industry (epi) technology in the atmosphere pollution treating flour dust, gradually adopts the one-time dedusting system that technology is simple, running resistance is little, easy to maintenance.But, the dust granules thick flue gas that perhaps have sticky dust high for dust content in order to prolong the service life of sack cleaner filter bag, guarantees the efficiency of dust collection of electric cleaner, can before deduster, increase pre-dedusting device usually.At present; Use more pre-dedusting device to be cyclone dust collectors; But because the resistance of cyclone dust collectors at 700～1000Pa, needs certain floor space, so to the dust pelletizing system on a lot of old production lines; Because of receiving the influence of place and original tail exhaust blower negative pressure, often there is not condition to increase cyclone dust collectors.Therefore, cyclone dust collectors only are fit to the well-to-do or new production line use in place.

The utility model content

The purpose of the utility model is, the dust granules thick flue gas that perhaps has sticky dust high to dust content; Provide a kind of simple in structure, safe and reliable, resistance is low, need not the pipeline pre-dedusting device of floor space, thereby guarantee the efficiency of dust collection of secondary filter and the life-span of consumable accessory.

Its technical scheme is: a kind of pipeline pre-dedusting device; It is characterized in that: it is by casing; Ash bucket, deflector, track and form by the rapping apparatus that electromagnetic vibrator, rubber sleeve, vibrating rod sleeve pipe, vibrating rod, rapping seat and round steel constitute; The left and right sides of said casing is communicated with trumpet-shaped into and out of the air port respectively, and the bottom of casing is communicated with ash bucket; Be interval with three pairs of upper and lower tracks in the casing; Staggeredly respectively between the three pairs of upper and lower tracks install that trumpet-shaped corresponding and upper and lower side all is equipped with the deflector framework of roller into and out of the air port with casing, the multi-disc deflector all is installed in each deflector framework from top to bottom; Rapping apparatus is installed in the top of casing, and the vibrating rod lower end connects successively in its vibrating rod sleeve pipe rapping seat and round steel extend in the casing, and the round steel deflector framework interior with being arranged on casing is connected.

The utility model has the advantages that: casing adopts trumpet-shaped into and out of the air port, makes the air-flow that gets in the casing obtain buffering, has reduced the SR of whole pre-dedusting device; Three roads are staggered to be installed in the casing and the deflector of installing in the corresponding deflector framework of trumpet-shaped air inlet; The dust of most crude particle in the flue dust and viscosity class stopped fall in the ash bucket or be bonded on the deflector; Therefore; The utility model is high to dust content, dust granules thick or have the preliminary treatment of sticky dust flue gas, and especially to similar RF kiln, to go out the pretreating effect of small coal tar very good to carrying sufficient sticky contaminant of unburned and wash rice in its flue gas secretly; Avoided this type of dust to cause air-vent to stop up, perhaps the pole plate polar curve has been caused corona blocking filter bag of dust collector; And installation site that the deflector framework is staggered and the deflector angle in the deflector framework can be adjusted according to the air intake angle; The rapping apparatus that install at the casing top can be realized the automatic ash removing to deflector; In addition, the utility model is simple in structure, safe and reliable, can be directly installed between the preceding dedust air duct of deduster, need not floor space, and running resistance is less than 500Pa, and Maintenance free when normally using uses no consumable accessory for a long time, and running rate is high.It not only is adapted to the dust pelletizing system on the old production line, uses when equally also being applicable to newly-built dust pelletizing system, has extremely strong adaptability.

The specific embodiment

As shown in the figure, a kind of pipeline pre-dedusting device, by casing, ash bucket, deflector, track and form by the rapping apparatus that electromagnetic vibrator 91, rubber sleeve 92, vibrating rod sleeve pipe, vibrating rod, rapping seat and round steel constitute.The left and right sides of casing 3 is communicated with trumpet-shaped into and out of the

air port

2,10 respectively, and the bottom of casing is communicated with ash bucket 5, and the ash hole of ash bucket is provided with unloading valve 6.Be interval with three pairs of upper and lower tracks 8 in the casing; Staggeredly respectively between the three pairs of upper and lower tracks install that trumpet-shaped corresponding and upper and lower side all is equipped with the deflector framework of roller into and out of the air port with casing, multi-disc deflector 7 all is installed in each deflector framework from top to bottom.Rapping apparatus 9 is installed in the top of casing, and the rapping seat 95 that vibrating rod 94 lower ends connect successively in its vibrating rod sleeve pipe 93 extends in the casing with round steel 96, and the round steel direction is vertical with the deflector framework, is connected with three deflector frameworks respectively in the staggered place.

For ease of to the installation of deflector framework, adjustment and to the maintenance and the cleaning of deflector, be provided with access door 4 at the rear side of casing.

During use; This pipeline pre-dedusting device is installed on the dedust air duct 1 before the deduster; Ash-laden gas gets into casing 3 from trumpet-shaped air inlet 2; The staggered interior deflector 7 with the interior installation of the corresponding deflector framework of trumpet-shaped air inlet of casing that is installed in warp three roads washes away, and the dust of most crude particle and viscosity class is bonded on the deflector or falls in the ash bucket 5, through unloading valve 6 continuous or timing discharges.Flue gas then enters dedust air duct entering secondary filter through trumpet-shaped air outlet 10 and proceeds dedusting.When the long-time dust stratification of deflector influences the normal dedusting in the casing and ventilates; Can start electromagnetic rapping device 9 carries out automatic ash removing on the one hand; Also can open access door 4 on the other hand; The deflector framework that is installed on the track 8 is extracted out, the deflector in the deflector framework is overhauled or clears up.
