Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1-2, the bag-type adsorbent particle purification device comprises a casing 1, two layers of partition boards 2 are horizontally arranged in the casing 1, the partition boards 2 divide the casing 1 into a lower purification chamber a, an upper purification chamber b and a gas purification chamber c, a mist-blocking screen is installed in the lower purification chamber a, the lower purification chamber a is divided into a pretreatment area and a filter bag area by the mist-blocking screen, the gas purification chamber c is provided with an air outlet pipe 3, the pretreatment area is provided with an air inlet pipe 4, a dust-removing filter bag 5 is installed in the filter bag area, an upper opening of the dust-removing filter bag 5 is communicated with the upper purification chamber b, a rotary dust remover 6 is installed in the upper purification chamber b, an air outlet end of the rotary dust remover 6 is communicated with the gas purification chamber c, and the bottom of the casing 1 is connected with a dust collecting hopper 7. During the in-service use, the flue gas gets into the preliminary treatment district through hindering the fog silk screen interception, gets into the filter bag district after making vapor in the flue gas condense and removes dust for the first time, and the first filterable flue gas gets into the clean room, carries out secondary dust removal through rotatory dust remover after, gets into the air inlet chamber, discharges through the outlet duct, and dust collection efficiency is high, improves life.

In this embodiment, hinder the fog silk screen and include two just to the wire mesh 8 that sets up, two the upper end of wire mesh 8 with the top fixed connection of clean room a down, two the both sides of wire mesh 8 all with 1 interior wall connection of casing, two the lower extreme of wire mesh 8 is connected with a diversion device 9, wire mesh 8, baffle 2, casing 1 and diversion device 9 enclose and establish into the preliminary treatment district, the inner of intake pipe 4 stretches into the preliminary treatment district. During the in-service use, the middle part of lower clean room is pretreatment area, and the both sides in pretreatment area are the filter bag district, and the flue gas through the dehumidification gets into the filter bag district of both sides from pretreatment area, improves flue gas treatment capacity.

In this embodiment, the water diversion device 9 includes a water receiving bucket 91, an upper edge of the water receiving bucket 91 is connected with a bottom edge of the metal wire mesh 8 and an inner wall of the housing 1, and a top point of the water receiving bucket 91 is connected with a water guide pipe 92. During actual use, the condensed water vapor can be led out in time.

In this embodiment, the rotary dust collector 6 comprises a rotary filter bag 61, an upper opening of the rotary filter bag 61 penetrates through the partition board 2 above the rotary filter bag and is connected with the rotary filter bag in a sealing manner, a rotary table 62 is arranged at the bottom of the rotary filter bag 61, and a driving motor 63 is arranged between the rotary table 62 and the partition board 2 below the rotary table. During the in-service use, driving motor 63 drives rotatory filter bag rotatory, drives the spiral rising of flue gas, and the particulate matter that floats to rotatory filter bag surface along with the flue gas can be thrown away from rotatory filter bag after doing short period circular motion, and after striking the casing, loses power, and the dust exhaust pipe 10 through installing in last clean room b is discharged in the free fall under the influence of gravity.

In this embodiment, there are a plurality of dust filter bags 5, and the plurality of dust filter bags 5 are symmetrically disposed on the outer sides of the two metal wire meshes 8. During the in-service use, the upper shed of dust bag 5 runs through the baffle of below to can dismantle rather than being connected, conveniently maintain the clearance, the opening part of dust bag is equipped with ash blocking swash plate 11, avoids going up the dust in the clean room and gets into in the dust bag.

In this embodiment, the air permeability of the dust-removing filter bag 5 is greater than that of the rotary filter bag 61. During the in-service use, because the humidity of the flue gas in the clean room is greater than the flue gas humidity in last clean room down, through set up the filter bag of different gas permeability in last clean room down, can adjust the air current equipartition, can avoid again that slight dust is along with the air current discharges, influences dust removal effect.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and that those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
