Detailed Description
The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1, a tower type flame arrester applied to front end pretreatment of a bag-type dust collector comprises a tower body 1, wherein an air inlet 2 is formed in one side of the lower part of the tower body 1, an air outlet 3 is formed in the top of the tower body 1, a dust falling area 4 and a fire retarding area 5 are sequentially formed in the tower body 1 from bottom to top, a centrifugal separator 6 and a plurality of damping plates 7 are sequentially arranged in the fire retarding area 5 from bottom to top, the air inlet 2 is arranged above the dust falling area 4 and communicated with an air inlet of the centrifugal separator 6, and an air outlet of the centrifugal separator 6 faces upwards.
Specifically, the bottom one side of the ash falling zone 4 is provided with an ash outlet 8, and the ash outlet 8 is provided with a gate valve 9, so that falling particles can be conveniently collected and discharged.
