Abstract

A louver-type curved plate gravity dust collector, which includes an air inlet, an air outlet, a louver-type bent-plate settlement area, a partition, and a dust collector. One side of the louver-type bent plate settlement area is provided with a dust collector, the middle part of the louver-type bent plate settlement area is provided with a louver-layer bent plate, and the upper part of one side of the louver-type bent plate settlement area is provided with an air outlet, and the distance between the air outlet and the bent plate There is a vertical partition between them, the dust-laden gas enters from the air inlet, and passes through the louvered bent plate settlement area to achieve secondary purification. After the dust particles fall, they are collected in the lower dust particle collector, and finally the gas passes through the partition The lower part is discharged from the air outlet.

Description

Louvered bent plate gravitational precipitator

Technical field

The utility model relates to a kind of deduster, relates in particular to a kind of louvered bent plate gravitational precipitator.

Background technology

Common fire coal boiler fume dust arrester has fountain, venturi-type, cyclone type, impact purification formula etc.; Usually its series connection is used for improving the efficiency of dust collection people, but there is the defective that floor space is big, equipment cost is higher in the deduster after the existing repacking combination.

Summary of the invention

The louvered bent plate gravitational precipitator that the purpose of the utility model has been to provide a kind of structure economics, has taken up space little.

The utility model is realized like this; It comprises air inlet, gas outlet, louvered bent plate decanting zone, dividing plate, grit trap; The top that it is characterized in that louvered bent plate decanting zone is provided with air inlet, and a side of bottom is provided with the grit trap, and the middle part of louvered bent plate decanting zone is provided with the bent plate of blinds layer; The opposite side top of louvered bent plate decanting zone is provided with the gas outlet, is provided with vertical clapboard between gas outlet and the said bent plate; The bent plate that is shaped as near air inlet one side of described bent plate is that middle bent is protruding, and the shape that two ends sink be the rising of tilting of a end near dividing plate near the bent plate of dividing plate, the shape of other end bending subsidence.

The technique effect of the utility model is: dusty gas gets into from air inlet, with the bent plate collision of blinds layer in the louvered bent plate decanting zone, because gas is different with grit gravity; Thereby it is different with shutter collision back momentum loss; Near the bent plate of air inlet one side is that middle bent is protruding, the shape that two ends sink, and grit falls along the both sides near the bent plate of air inlet; Gas accomplishes for the first time purifying then to the bent plate diffluence near dividing plate; Bent plate near dividing plate is the end inclination rising near dividing plate, the shape of other end bending subsidence, and air-flow and grit are located to flow along bent plate together from low to high, and grit reaches purification for the second time owing to the gravity effect is fallen; Be collected in after grit falls in the grit trap of bottom, last gas is discharged through the lower partition and by the gas outlet.

The specific embodiment

As shown in Figure 1; The utility model realizes that like this it comprises air inlet 1, gas outlet 6, louvered bent plate decanting zone 2, dividing plate 5, grit trap 3, and the top of louvered bent plate decanting zone 2 is provided with air inlet 1; One side of bottom is provided with grit trap 3; The middle part of louvered bent plate decanting zone 2 is provided with the bent plate 4 of blinds layer, and a upper lateral part of louvered bent plate decanting zone 2 is provided with gas outlet 6, is provided with vertical dividing plate 5 between gas outlet 6 and the said bent plate 4; Dusty gas gets into from air inlet 1, with bent plate 4 collisions of blinds layer in the louvered bent plate decanting zone 2, because gas is different with grit gravity; Thereby it is different with bent plate 4 collision back momentum losses; Near the bent plate 4 of air inlet 1 one sides is that middle bent is protruding, the shape that two ends sink, and grit falls along the both sides near the bent plate 4 of air inlet 1; Gas accomplishes for the first time purifying then to bent plate 4 diffluences near dividing plate 5; Bent plate 4 near dividing plate 5 is the end inclination rising near dividing plate 5, the shape of other end bending subsidence, and air-flow and grit are located to flow along bent plate 4 together from low to high, and grit reaches purification for the second time owing to the gravity effect is fallen; Be collected in after grit falls in the grit trap 3 of bottom, last gas is discharged through dividing plate 5 bottoms and by gas outlet 6.

Claims
