Abstract
The invention discloses a dry quenching primary dust collector structure and a dedusting method thereof. The dry quenching primary dust collector structure includes a dust collector inlet, a dust collector outlet, a dedusting channel, and a dust hopper arranged at the bottom of the dedusting channel; the dedusting channel is provided with at least one Z-shaped channel structure, a corner of the Z-shaped channel structure is transversely provided with two dedusting retaining walls which are arranged oppositely, a gas flow channel is formed between the retaining walls, and the dust hopper is arranged at the bottom of the Z-shaped channel structure. Compared with the prior art, the dry quenching primary dust collector structure has the beneficial effects that the dry quenching primary dust collector structure has an original upper retaining wall structure cancelled, the Z-shaped channel structure is arranged, and the two transversely oppositely arranged dedusting retaining walls are added, so that the overall strength of a primary dust collector is improved, and the dedusting efficiency is increased; the structure is more steady, the shedding of brick bodies is reduced, the service life of the primary dust collector is extended, and the maintenance time and costs of spare parts are saved.
Description
Technical field
The present invention relates to Dry Quenching Technology field, particularly relate to a kind of cork dry quenching disposable dust remover structure and dust collection method thereof.
Background technology
Dry coke quenching is the very important link of steel industry coke making process one, and the dry coke quenching deduster used at present mainly contains gravity settling chamber, inertial dust separator and cyclone dust collectors.Gravity settling chamber mainly removes the dust in gas by gravitational settling mode, reliability is low and volume is large; And the inertial dust separator containing top barrier wall structure the most frequently used at present, due to the long-term expanded by heating of top barricade, easy appearance distortion, intensity declines, and brick very easily comes off, and weakens body enabling capabilities, even cause barricade integral sinking, not only affect dust removing effects, the brick body blocking come off also can cause the coke breeze discharger blocking of disposable dust remover bottom, and serious conditions even jeopardizes dry coke quenching and normally produces.
Summary of the invention
The object of this invention is to provide a kind of cork dry quenching disposable dust remover structure and dust collection method thereof, zigzag dedusting channel design is provided with in deduster, this cork dry quenching disposable dust remover structure does not need accurately to control recyclegas flow, gas flow resistance is less, can not have an impact to dry quenching system pressure balance, cancel original top barricade thus eliminate barricade sinking and brick body comes off, be conducive to improving disposable dust remover service life, save repair time and spare part expense.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of cork dry quenching disposable dust remover structure, comprises deduster entrance, house outlet, dedusting passage and is arranged on the ash bucket of dedusting channel bottom; Described dedusting passage is provided with at least one zigzag channel design, two dedusting barricades are horizontally arranged with in the corner of described zigzag channel design, two dedusting barricades are oppositely arranged, and be gas channel between barricade, described ash bucket is arranged on the bottom of zigzag channel design.
Knuckle α: 45 °≤α≤90 ° of described zigzag channel design.
The length L1 of described two dedusting barricades and L2 sum are less than the half of dedusting channel width D.
A kind of dust collection method of cork dry quenching disposable dust remover structure, gas enters disposable dust remover dedusting passage by deduster entrance, the metope A of zigzag channel design plays guide effect to gas, makes the dust in gas be settled down in ash bucket by effect of inertia, changes a gas flow; The guide effect of gas again by metope B after break-in in zigzag channel design, makes the second time of the dust in gas be settled down in ash bucket by effect of inertia; Finally make the dust in gas be settled down in ash bucket by an effect of inertia again at the dedusting barricade of zigzag channel design outlet corner, gas enters steam generator system by disposable dust remover outlet.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of cork dry quenching disposable dust remover structure and dust collection method thereof, eliminate original top barrier wall structure, is provided with zigzag channel design and with the addition of the dedusting barricade that two transverse directions are oppositely arranged, improve the bulk strength of disposable dust remover, improve efficiency of dust collection.Structure is more firm, reduces coming off of brick body, extends the service life of disposable dust remover, save repair time and spare part expense.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in detail, but it should be noted that enforcement of the present invention is not limited to following embodiment.
As Figure 1-Figure 2, a kind of cork dry quenching disposable dust remover structure, comprises deduster entrance 1, house outlet 2, dedusting passage and is arranged on the ash bucket 5 of dedusting channel bottom; Described dedusting passage is provided with at least one zigzag channel design 3, two dedusting barricades 4 are horizontally arranged with in the corner of described zigzag channel design 3, two dedusting barricades 4 are oppositely arranged, and be gas channel between barricade, described ash bucket 5 is arranged on the bottom of zigzag channel design 3.
Knuckle α: 45 °≤α≤90 ° of described zigzag channel design.
The length L1 of described two dedusting barricades 4 and L2 sum are less than the half of dedusting channel width D.
A kind of dust collection method of cork dry quenching disposable dust remover structure, gas enters disposable dust remover dedusting passage by deduster entrance 1, the metope A6 of zigzag channel design 3 plays guide effect to gas, makes the dust in gas be settled down in ash bucket 5 by effect of inertia, changes a gas flow; The guide effect of gas again by metope B7 after break-in in zigzag channel design 3, makes the second time of the dust in gas be settled down in ash bucket 5 by effect of inertia; The dedusting barricade 4 finally exporting corner in zigzag channel design 3 makes the dust in gas be settled down in ash bucket 5 by an effect of inertia again, and gas exports 2 by disposable dust remover and enters steam generator system.
When the knuckle α of zigzag channel design 3 is too little, can gas flow resistance be increased, affect dry quenching system pressure balance, also increase disposable dust remover simultaneously and build difficulty by laying bricks or stones; If angle [alpha] is too large, then efficiency of dust collection can be reduced.
Dedusting barricade 4 is for build by laying bricks or stones from bottom to top.Wherein, L1 and L2 sum should be less than the half of dedusting channel width D, when L1 and L2 sum is excessive, can increase gas flow resistance, affect pressure balance in dry coke quenching, makes barricade middle air flow speed excessive simultaneously, affects efficiency of dust collection.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
