Abstract
The utility model discloses an ultrahigh temperature bag type dust remover with a dust removal device, which comprises a box body of the bag type dust remover, a dust bucket, an electric control box and an air compressor. The utility model is characterized in that the top end of an air intake chamber of the box body of the bag type dust remover is provided with an acoustic vibration dust removal device which is composed of a sound producing device and a horn, and an electromagnetic valve which is controlled by the electric control box is arranged on an air intake pipe between the sound producing device and the air compressor; an upper pressure sensor is arranged in a fume inlet, a lower pressure sensor is arranged in a fume outlet and the upper pressure sensor and the lower pressure sensor are both connected with the electric control box through conducting wires. The utility model has the structure that the top part of the box body of the ultrahigh temperature bag type dust remover is provided with the acoustic vibration dust removal device, and uses an acoustic vibration dust removal mode, namely, a dust layer is destroyed through a resonant mode to reach the goal of dust removal. The utility model uses the acoustic vibration dust removal device to remove dust at a definite time, and has the advantage of good effect on dust removal.
Description
Technical field
The utility model relates to the deashing device of sack cleaner, especially relates to a kind of superhigh temperature bag duster with deashing device.
Background technology
What present common sack cleaner generally adopted is the pulse of compressed air deashing, its mechanism is: the aeration of winding-up air-flow is with filter bag contraction-likely outwards heaving distortion, vibrating to the center by transition state, the dust layer of filter bag outer surface is broken, air pulse makes a bag interior air vibration simultaneously, the vibration of drive filter bag realizes that the process on dust disengaging filter bag surface reaches the effect of deashing.In this process, it is a crucial step to destroy dust layer that the winding-up air-flow makes filter bag change shape, does not have the effect winding-up effect of this destruction dust layer to have a greatly reduced quality.Make of metallic fiber as filter bag, this filter bag has certain intensity, can not use a bag cage framework.But deashing mechanism according to pulse jet, the metallic fiber filter bag is not suitable for using the purge mode of pulse of compressed air winding-up, because general compressed air spraying pressure can not make the metallic fiber filter bag deform because hardness is excessive, can not destroy dust layer, ash-removal effect is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of sound wave vibrations deashing device that adopts to carry out regularly deashing, superhigh temperature bag duster that ash-removal effect is good.
The purpose of this utility model is achieved in that the utility model comprises the sack cleaner casing, ash bucket, electric cabinet and air compressor, sidewall at the sack cleaner casing is processed with smoke air inlet and flue gas gas outlet, on the card in the sack cleaner casing filter bag is installed, feature is on the inlet chamber top of sack cleaner casing the acoustic vibration deashing device of being made up of sound-producing device and loudspeaker to be installed, the magnetic valve that is subjected to electric cabinet control is installed on the air inlet pipe between sound-producing device and the air compressor, the upward pressure sensor is installed in smoke air inlet, in the flue gas gas outlet, lower pressure sensor is installed, the upward pressure sensor, lower pressure sensor all is connected with electric cabinet by lead.
Described filter bag is the metallic fiber filter bag.
The utility model is at the top of superhigh temperature bag duster casing the acoustic vibration deashing device to be installed, and adopts the mode of sound wave vibrations deashing, promptly destroys dust layer by the mode of resonance, reaches the purpose of deashing.Its deashing principle is: flue gas enters in the deduster casing from the smoke air inlet of superhigh temperature deduster upper side, and after filtering through the metallic fiber filter bag, clean flue gas is discharged from the flue gas gas outlet at middle part.In filter process, attached being on the increase on metallic fiber filter bag surface as dust, dust remover resistance constantly increases.When resistance reaches predetermined set value, electric cabinet is controlled magnetic valve automatically and is opened, compressed air impacts the diaphragm of sound-producing device through magnetic valve, sonic horn begins to produce the vibrations of extremely low frequency, this low-frequency vibration can produce resonance with the particulate combining mechanism attached to the filter surface, makes the dust layer fragmentation, under the gravity effect, dust falls, and down enters the ash bucket of deduster bottom.When resistance dropped to predetermined set value, electric cabinet was controlled closed electromagnetic valve automatically, and sounding stops, and deashing is finished.Setting value is the difference of the measured value of the measured value of lower pressure sensor and upward pressure sensor.Also can when debugging, set the startup of sound wave dust separator and close down the time timing deashing according to operating condition.Therefore the utlity model has and adopt sound wave vibrations deashing device to carry out regularly deashing, advantage that ash-removal effect is good.
Description of drawings
Fig. 1 is a sectional structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
The utility model comprises sack cleaner casing 1, ash bucket 5, electric cabinet 9 and air compressor 10, sidewall at sack cleaner casing 1 is processed with smoke air inlet 12 and flue gas gas outlet 7, on the card 3 in sack cleaner casing 1 filter bag 4 is installed, inlet chamber 2 tops at sack cleaner casing 1 are equipped with the acoustic vibration deashing device of being made up of sound-producing device 14 and loudspeaker 15 16, the magnetic valve 13 that is subjected to electric cabinet 9 controls is installed on the air inlet pipe 11 between sound-producing device 14 and the air compressor 10, upward pressure sensor 8 is installed in smoke air inlet 12, lower pressure sensor 6 is installed, upward pressure sensor 8 in flue gas gas outlet 7, lower pressure sensor 6 all is connected with electric cabinet 9 by lead.
Described filter bag 4 is the metallic fiber filter bag.
