Abstract

The utility model discloses a multi-tube cyclone duster, which comprises a casing, a cyclone, a smoke inlet port, a smoke outlet port, etc. The multi-tube cyclone duster is characterized in that the casing is provided with three sections; the internal part of the intermediate section of the casing is provided with a partition board; the casing is divided into an upper hollow cavity and a lower hollow cavity which are communicated through an exhaust core tube which passes through the partition board; the internal part of the exhaust core tube is provided with a spiral flow deflector; the smoke inlet port enters the lower hollow cavity of the casing along the tangential direction; the smoke exhaust port is arranged on the upper hollow cavity; the first-level spiral case type dust collection can be formed between the smoke inlet port and the casing, and however, the flow deflector in the air exhaust core tube can form the two-stage dust collection. The utility model has the advantages of reasonable structure, small smoke resistance, and easy maintenance, and the dust collecting efficiency of the multi-tube cyclone duster can reach to 95%.

Description

A kind of multicyclone deduster

The utility model relates to a kind of boiler smoke dust arrester, particularly relates to a kind of multicyclone deduster.

In the prior art, deduster is divided into two kinds of wet type and dry types, dedusting of wet scrubber collection and removing and harmful gas dual-use function, but complex structure, floor space is big, and, effective solution is not also found in the secondary pollution that it produced, so do not obtain popularizing widely.At present, widely the dry collector kind of Shi Yonging is also a lot, commonly used have cyclone dust collectors and a centicell unit, cyclone dust collectors are divided into single-stage and twin-stage again, the single-stage deduster is owing to the dust removing effects difference is eliminated, and the dual stage cyclone deduster constitutes complex structure side by side by two scroll casing type whirlwind not of uniform size, and the flue gas pipeline of flowing through is long, resistance is big, needs the powerful air-introduced machine of configuration, and efficiency of dust collection can only reach 85%, in addition, at application number is disclosed in 88217848.2 " centicell unit ", adopts many group whirlwind minor structures, and every group of whirlwind is by the whirlwind tube, exhaust core pipe and flow deflector are formed, flow deflector is located at the exhaust core pipe outside, flue gas directly carries out dedusting through flow deflector from advancing mouth, and the deduster of this structure is because flow deflector is intensive, passage is narrow, flue gas resistance is big, is easy to stop up, in addition, be primary dust removing, dust removing effects is also undesirable.In addition, above-mentioned dry collector is monoblock type, not easy-maintaining and maintenance.

The purpose of this utility model is at the deficiencies in the prior art, provides a kind of simple in structure, takes up an area of for a short time, and flue gas resistance is little, be easy to maintenance and the high multicyclone deduster of efficiency of dust collection.

The utility model can be achieved by the following scheme, the housing of deduster is divided into three sections, be provided with a dividing plate in the stage casing, housing is divided into two cavitys up and down, exhaust core pipe passes dividing plate and makes cavity connection up and down, advancing mouth is located on the housing of dividing plate below with tangential direction, and form one-level scroll casing type cyclone dust collectors with housing, outlet flue then is located on the housing of top, be provided with the helical form flow deflector in the exhaust core pipe, form two-stage dust removal, the quantity of exhaust core pipe is provided with 1-12 according to the big I of boiler tonnage.

Compared with prior art, the utlity model has simple in structurely, flue gas resistance is little, is difficult for stopping up, and easy-maintaining maintenance and efficiency of dust collection can reach 95% with first-class advantage.

Accompanying drawing 1 is the utility model front view.

Accompanying drawing 2 is the attached views of the utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further, deduster is a vertical type, be applicable to the dedusting of boiler below 10 tons, for the boiler of different tonnages, the overall dimensions of its deduster are even different with the quantity of exhaust core pipe, ordinary circumstance, to 1 ton of boiler, exhaust core pipe is established 1-2, and the deduster diameter is 600mm, high 700mm, to 10 tons of boilers, exhaust core pipe can be established 8-12, and the deduster diameter is 1900m, high 2300mm, no matter establish several exhaust core pipes, they do as a whole, and the housing center should be departed from its center, promptly be partial to the opposite side relative, bigger space arranged to guarantee the cyclone dust removal of one-level scroll casing type with advancing mouth.

Among the figure: 1-support, 2-dust collecting box, 3-housing, 4-exhaust core pipe, 5-dividing plate, 6-advance mouth, 7-Outlet flue, 8-flow deflector.

Claims

1, a kind of multicyclone deduster, form by housing, whirlwind, smoke inlet and outlet etc., it is characterized in that housing is divided into three sections, in the stage casing, be provided with a dividing plate, housing is divided into two cavitys up and down, exhaust core pipe passes dividing plate and makes cavity connection up and down, advance mouth and be located on the housing of dividing plate below with tangential direction, and form one-level scroll casing type cyclone dust collectors with housing, outlet flue is located on the housing of dividing plate top, be provided with the helical form flow deflector in the blast pipe, form two-stage dust removal.

2, deduster according to claim 1, the quantity that it is characterized in that exhaust core pipe are 1-12.
