Description
Technical field
The utility model relates to the flue gases purification field, the efficient multi-tube dust cleaner of particularly a kind of twin-stage.
Background technology
At present, the large-scale pelletizing plant employing belt pelletizer or the chain grate machine rotary kiln of steel and iron industry scale more than 1,000,000 tons, hot blast temperature reaches 450 ℃～550 ℃ before the pelletizing preheating fan, and electric precipitation and bag-type dust are all inapplicable, generally adopt hot multi-tube dust cleaner.This deduster is a primary dust removing, comprises a plurality of whirlwind in the deduster, and the centrifugal force that utilizes whirlwind to produce will be separated greater than the dust particle of critical particle, and efficiency of dust collection is low, about 85%.Each whirlwind adopts the upper axial air intake, force to change into swirling eddy by helical blade or petal leaves, because of the air inlet speed of high velocity air surpasses 20m/s, blade and whirlwind are produced wearing and tearing, cause the sub-internal surface gaps of blade and whirlwind to increase, reduce the service life of efficiency of dust collection and blower fan.
Summary of the invention
The purpose of this utility model is to provide a kind of purification of high-temperature flue gas and efficient multi-tube dust cleaner of twin-stage that dust reclaims of being applicable to.
The utility model purpose realizes by following technical proposals:
The efficient multi-tube dust cleaner of a kind of twin-stage of the present utility model, comprise support, housing, air inlet, air outlet, ash bucket, it is characterized in that by the primary dust removing district that is positioned at the air inlet end, the primary dust removing district forms in adjacent two-stage dust removal district therewith, described primary dust removing district is made up of the expansion chamber of cyclone group that is positioned at primary dust removing district front end and is connected with air inlet and rear end, primary dust removing district, the lower end of this expansion chamber is connected with the primary dust removing ash bucket, described two-stage dust removal district is provided with a dividing plate two-stage dust removal is divided into, following two parts, top is divided into the purified gas space, this purified gas space is connected with air outlet, the bottom is divided into the sub-workspace of whirlwind, the wireway of this whirlwind is connected with the purified gas space by dividing plate, the lower end of the sub-workspace of described whirlwind fixes with the two-stage dust removal ash bucket and is connected
Described whirlwind is tangential air intake.
The material of described whirlwind is a heat-resistant and wear-resistant material.
The operation principle of the efficient multi-tube dust cleaner of twin-stage of the present utility model is:
Ash-laden gas at first enters the cyclone group of primary dust removing district front end, ash-laden gas enters the cyclone group with higher speed, because the unit weight of dust is far above the unit weight of gas in the ash-laden gas, dust (coarse granule) is under inertia force and gravity effect, from ash-laden gas, separate downwards forward,, big dust particle is got rid of into ash bucket, reach the thick purpose that purifies of primary dust removing, then at the expansion chamber of rear end, primary dust removing district sedimentation part grit once more; Ash-laden gas through the primary dust removing district enters the sub-workspace of lower end whirlwind, two-stage dust removal district by two-stage dust removal district air intake again, ash-laden gas is tangential air intake in the sub-import of whirlwind, the inside that enters whirlwind is swirling eddy, organize dedusting once more through secondary multi-cyclone, isolated dust is got rid of into ash bucket, reach the purpose that purifies flue gas, reclaims dust.
The advantage of the efficient multi-tube dust cleaner of this kind twin-stage is:
The efficiency of dust collection height, it is little to wear and tear, and improves the service life of air-heater.This cleaner of use was checked in several years in the production technology of factories such as pelletizing plant of Shoudu Iron and Steel Co mining company, sintering plant, the suitable special steel of packet header moral, and efficiency of dust collection still remains on 95% so far---and more than 96%, improve air-heater and reach 4 years service life.

The specific embodiment
Given embodiment further specifies the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the efficient multi-tube dust cleaner of a kind of twin-stage of the present utility model, comprise support 1, housing 3, air inlet 7, air outlet 4, ash bucket 2,9, it is characterized in that by the primary dust removing district 5 that is positioned at air inlet 7 ends, the primary dust removing district forms in 5 adjacent two-stage dust removal districts 6 therewith, described primary dust removing district 5 is made up of the expansion chamber that is positioned at primary dust removing district 5 front ends and the cyclone group 10 that is connected with air inlet 7 and 5 rear ends, primary dust removing district, the lower end of this expansion chamber is connected with primary dust removing ash bucket 9, described two-stage dust removal district 6 is provided with a dividing plate 8 two-stage dust removal district 6 is divided into, following two parts, top is divided into the purified gas space, this purified gas space is connected with air outlet 4, the bottom is divided into whirlwind 12 workspaces, the wireway 11 of this whirlwind 12 is connected with the purified gas space by dividing plate 8, the lower end of described whirlwind 12 workspaces fixes with two-stage dust removal ash bucket 2 and is connected
Described whirlwind 12 is tangential air intake.
The material of described whirlwind 12 is a heat-resistant and wear-resistant material.
The advantage of this kind double-stage high-efficient multiclone collector is:
The efficiency of dust collection height, it is little to wear and tear, and improves the service life of air-heater.
