specific Embodiment approach 1

[0019] Specific implementation mode two: as Figure 1~3 As shown, the sub-chamber reverse blowing and dust cleaning device in this embodiment also includes a sliding support member 11 placed in the clean air chamber 15, and the sliding support member 11 is composed of a support frame 11-1 and four pulleys 11-2. The support frame 11-1 is fixed on the outer side wall of the movable anti-air outlet 7, the pulley 11-2 is installed on the bottom end of the support frame 11-1, and the pulley 11-2 is in contact with the upper end surface of the cover plate 19 , the pulley 11-2 slides along the upper end surface of the cover plate 19 (the upper end surface of the cover plate 19 acts as a “track”). Other components and connections are the same as those in the first embodiment.

[0020] Specific implementation mode three: as Figure 1~4 As shown, the transmission mechanism 5 in this embodiment includes a chain 5-9, a driving sprocket 5-10 and a driven sprocket 5-11. The transmission mechanism 5 is placed above the sliding support member 11, and the chain 5-9 Connect with the connecting ear on the side wall of the movable anti-blowing outlet 7; the speed-regulating motor 22 in the compartment anti-blowing dust cleaning device drives the driving sprocket 5-10 to rotate; the transmission mechanism 5 and the telescopic anti-blowing pipe 9 The air inlet end of the air inlet is installed on the housing 6 of the compartment back blowing and dust cleaning device fixed on the two outer walls of the upper part of the box body 1. When the chain 5-9 traction movable type anti-blow outlet 7 back-blowing and dust-cleaning, the telescopic anti-blow pipe 9 is also pulled along with expansion and contraction, guarantees the unimpeded flow of back-blowing air. Other co...

[0021] Specific implementation mode four: as Figure 1~5 As shown, the dust remover in this embodiment also includes a sound wave generator 10, and the sound wave generator 10 is installed at the air intake end of the telescopic back-blow pipe 9; the installation position of the sound wave generator 10 ensures that the blowback dust At this time, the sound wave enters the inner surface of the filter bag along with the blowback airflow, and the direction of the low-frequency sound wave emitted by the sound wave generator 10 is consistent with the direction of the blowback airflow. The acoustic wave generator 10 and the chamber-by-chamber back-blowing and dust-cleaning device carry out mouth-to-mouth positioning and dust-cleaning of the chambers together, realizing the chamber-by-chamber back-blowing sound wave-assisted dust removal of the bag filter. The sound wave generator is installed at the inlet end of the blowback pipe. When blowback is used to remove dust, the sound wave e...

Abstract

The invention discloses a sub-chamber back blowing bag type dust collector with a reciprocating movement back blowing air port, and relates to a bag type dust collector. The bag type dust collector can solve the problems that a deashing mechanism of the conventional bag type dust collector cannot realize port-to-port deashing chamber by chamber, the deashing effect is poor, the structure is complex, faults are easy to occur and the like. The bag type dust collector is technically characterized in that: a sub-chamber back blowing deashing device is arranged in a gas purifying chamber, one end of a telescopic back blowing gas pipe is connected with a deashing gas source for introducing back blowing deashing gas flow, and the other end of the telescopic back blowing gas pipe is connected with the movable back blowing air port; and a transmission mechanism draws the movable back blowing air port and the telescopic back blowing air pipe to reciprocate and move to the outlet of the small gas purifying chamber sequentially for performing port-to-port positioning back blowing deashing chamber by chamber. The sub-chamber back blowing bag type dust collector is mainly applied in dedusting treatment before smoke gas in power stations, metallurgy, chemical industry, mining, cement, grain processing and other industries is discharged.

Description

technical field [0001] The invention relates to a bag-type dust collector, in particular to a chamber-by-chamber reverse-blowing bag-type dust collector with reciprocating movement of a blow-back outlet. Background technique [0002] At present, bag filter is widely used in power station, metallurgy, chemical industry, mining, cement, grain processing and other industries. The working principle of the bag filter is: under the negative pressure of the induced draft fan, the dust-containing gas enters the dust chamber of the dust collector, and when passing through the filter bag mouth, the dust particles are blocked on the outer surface of the filter bag to form a dust layer. The filtered gas enters the clean gas chamber and is discharged to the atmosphere through the pipeline. With the prolongation of time, the dust layer will thicken, and the resistance of the dust collector will increase, so it needs to be cleaned. There are different types of bag filters, which are main...
