Inertial pre-dedusting flue gas distributor of deduster

Abstract

The invention discloses an inertial pre-dedusting flue gas distributor of a deduster. The flue gas distributor comprises a dust collector box. The dust collector box is divided by a card into an upper clean gas chamber and a lower flue gas chamber; the lower flue gas chamber comprises a pre-dedusting chamber and a cloth bag dedust chamber, which are communicated; the card in the cloth bag dedust chamber is hanged with a filter bag; the pre-dedusting chamber of the dust collector box is provided with an air inlet, and an air outlet is arranged on the upper clean gas chamber; the pre-dedusting chamber along the flue gas inlet direction is sequentially equipped with a plurality of flue gas pre-dedusting distribution mechanisms; the flue gas pre-dedusting distribution mechanism comprises a plurality of front groove-shaped baffles and rear groove baffles, which are vertically arranged on the pre-dedusting chamber; the notches of all the front groove-shaped baffles are arranged in the flue gas inlet direction; all notches of the rear groove-shaped baffles are arranged all against the flue gas inlet direction; every two adjacent front groove-shaped baffles buckle with one rear groove-shaped baffle; and a gap is left between each rear groove-shaped baffle and the buckled front groove-shaped baffle. The filter bag provided by the invention has the advantage of long service life.

Description

technical field [0001] The invention relates to a dust collector, in particular to a dust collector inertial pre-dust removal flue gas distribution device in the dust collector. Background technique [0002] The structure of the bag filter includes: a dust collector box, a smoke inlet pipe and a smoke outlet pipe. The dust collector box is divided into an upper clean room and a lower smoke room by a flower plate. The filter bag connected to the air chamber has an air inlet in the lower flue gas chamber of the dust collector box, and an air outlet in the upper clean air chamber; the smoke inlet pipe is connected with the air inlet of the lower flue gas chamber of the dust collector box The air outlet of the upper clean room of the dust collector box is connected with the smoke outlet pipe; the disadvantage of this bag filter is: because the dusty flue gas contains a large amount of large particles of dust (dust particle size greater than 50μm), When the dust-containing flue ...

[0002] The structure of the bag filter includes: a dust collector box, a smoke inlet pipe and a smoke outlet pipe. The dust collector box is divided into an upper clean room and a lower smoke room by a flower plate. The filter bag connected to the air chamber has an air inlet in the lower flue gas chamber of the dust collector box, and an air outlet in the upper clean air chamber; the smoke inlet pipe is connected with the air inlet of the lower flue gas chamber of the dust collector box The air outlet of the upper clean room of the dust collector box is connected with the smoke outlet pipe; the disadvantage of this bag filter is: because the dusty flue gas contains a large amount of large particles of dust (dust particle size greater than 50μm), When the dust-containing flue gas is discharged into the lower flue gas chamber through the smoke inlet pipe at a relatively high flue gas flow rate, since there is no flue gas pre-dust removal distribution device in the lower flue gas chamber, the dust-laden flue gas entering the lower flue gas chamber will be directly discharged into the lower flue gas chamber. The filter bag is impacted, and at the same time, the large particles of dust in the dusty flue gas will directly wash the filter bag, so that the filter bag is easily damaged, which not only greatly reduces the service life of the filter bag, but also reduces the filter bag.
