FIG. 1 is a top view of a precipitator in accordance with the present invention.

FIG. 2 is a sectional view of a dust collector A-A according to the present invention.

FIG. 3 is an isometric view of the duster of the present invention.

In the figure: the device comprises a cylinder body 1, a conical shell 2, a gas inlet pipe 2, an ash hopper 2, an ash discharge port 5, a support 6, a baffle 7, an inclined plate 8, a hand hole 9 and a gas outlet pipe 10.

Detailed Description

In the structural schematic diagram of the dust remover shown in fig. 1, the dust remover is arranged on an equipment foundation through a support (6), dust-containing gas enters the inside of an equipment cylinder (1) through a gas inlet pipe (3) and a conical shell (2), dust is prevented by a baffle plate 7 from descending at a speed and then is settled under the action of gravity, one part of dust is directly settled into a dust hopper 4, the other part of dust is settled onto an inclined plate 8 and then is settled into a dust discharging port (5), purified gas finally flows out of the inside of the equipment through a gas outlet pipe 10, the dust is finally discharged from the dust discharging port 5 through the dust hopper 4, and a hand hole 9 is used as an observation and dust cleaning port.

In the dust remover structural schematic diagram shown in fig. 2, dusty gas enters the barrel 2 by the gas inlet pipe 3 and the awl shell 2 later, because the gas passage enlarges and is the gas velocity reduction, be favorable to the gravity of dust to subside, baffle 2 through setting up the slope and arranging further stops not subsiding the dust, clean gas after the dust removal flows out from the equipment is inside through gas outlet pipe 2, setting up of crisscross slope baffle makes equipment structure very compact, the problem that traditional gravity subsides dust collecting equipment takes up an area of and the manufacturing cost is too high is solved.

In the axial view of the dust collector shown in fig. 3, the inclined plate 8 is arranged to facilitate the settled dust to fall into the dust hopper 4 and to be discharged from the dust discharge port 5.
