Novel combined bag dust collector

Abstract

The invention provides a novel combined bag dust collector. A centrifugal spiral drum pre-dust falling device and a bag type dust collecting device are respectively arranged on a frame and a support;an air inlet I of the centrifugal spiral drum pre-dust falling device is communicated with a dust air exhausting port and an air outlet I of the centrifugal spiral drum pre-dust falling device is communicated with an air inlet II of the bag type dust collecting device; the dust air passes the centrifugal spiral drum pre-dust falling device and the bag type dust collecting device for pre-dust falling and rough dust separation and then is fed into a bag type dust removing box which is connected with an air outlet II of the bag type dust collecting device, so that the dust-falling and dust separating treatment for the dust air can be realized. The novel combined bag dust collector is beneficial to the dry dust collection of the bag type dust collecting device and the bag type dust removing box; the dust removing efficiency is increased; the dust is prevented from quickly attaching to the bag under the effect of water in air; the dust-cleaning period and the service life of the bag are long; the maintenance and halting times of the dust collector are effectively reduced; the use value is ultrahigh.

Description

technical field [0001] The invention belongs to the technical field of dust collection equipment, and in particular relates to a novel combined bag dust collector. Background technique [0002] At present, the bag filter is to send the dust gas directly into the bag dust box, so that the bag gradually absorbs the moisture in the air, so that the dust quickly adheres to the surface of the bag. This method has low dust collection efficiency. At the same time, the bag The service life of dust cleaning is short, which not only affects the service life of the bag, but also increases the number of replacement and maintenance and shutdown, which affects normal production. It is necessary to improve the above problems. Contents of the invention [0003] The technical problem solved by the present invention is to provide a new type combined bag dust collector, which sends the discharged dust gas through the centrifugal spiral cylinder pre-dust reduction device and the bag-type dust...
