Be described above the loose dust stratification device of industrial kiln and the loose dust stratification device of industrial kiln concrete structure and Operation principle, a kind of concrete structure of the glass substrate production kiln for the disengaging of above two dust removing tool is explained below.

As shown in figure 4, the disclosure provides a kind of glass substrate production kiln, including flue 1 and connected with the flue 1 Regenerator 2, wherein, formed with hole 3 of skimming on flue 1 and/or regenerator 2, door 4 of skimming, flue 1 are blocked in the hole 3 of skimming On the ratio of cross-sectional area of area and flue 3 in hole 3 of skimming be 1%-5%, the area in the hole 3 of skimming in regenerator 2 and The ratio of the cross-sectional area of regenerator 2 is 0.5%-5%.

With the ratio of the cross-sectional area of flue 1 it is 1%-5% by the area design in the hole 3 of skimming on flue 1 due to being, It with the ratio of the cross-sectional area of regenerator 2 is 0.5%-5% to be by the area design in the hole 3 of skimming in regenerator 2.I.e., just Ensure that the loose dust stratification device of above-mentioned industrial kiln and industrial kiln dust exhaust apparatus can pass in and out flue and regenerator. So, more than 90% can be reduced by each taking off the area of cinder hole, and 90% can be reduced hence into the outside air amount in kiln More than.Further, since only need opening one to take off cinder hole when clearing up dust stratification every time, after appropriate sealing protection measure is taken, Even more so that reach negligible degree into the air capacity in kiln.Wherein sealing protection measure for example can be, Clog heat-preservation cotton between the loose dust stratification device of industrial kiln and the gap for taking off cinder hole, or in industrial kiln dust exhaust apparatus and Take off between the gap of cinder hole and clog heat-preservation cotton.

For example, the area for taking off cinder hole of regenerator of the prior art is generally 1.5m × 2m=3 ㎡, carried using the disclosure For glass substrate production kiln after, the area for taking off cinder hole in its regenerator is 0.3m × 0.3m=0.09 ㎡, 0.09/3 =0.03=3%.The i.e. new area for taking off cinder hole accounts for the 3% of the original area for taking off cinder hole, in theory, after an opening of skimming, outside The inlet of boundary's air reduces 1-3%=97%, can be ignored substantially, and this is not accounted in operating process also in addition, Heat-preservation cotton pay the seam is taken further to reduce the effect of intake.

So, it is directly proportional to the area for taking off cinder hole due to entering the air capacity in kiln, can be notable when draft is constant Ground reduces the area for taking off cinder hole.Therefore during kiln dust stratification is cleared up, from taking off in cinder hole the air that enters in kiln Amount can be reduced significantly, avoid having undesirable effect the melting process and glass substrate product quality of kiln.

Further to ensure the melting process of the product quality of glass substrate and kiln, area and the flue 1 in hole 3 of skimming The ratio of cross-sectional area be 1.5%-3%.

It is each in flue to be removed using the loose dust stratification device of above-mentioned industrial kiln and industrial kiln dust exhaust apparatus The dust stratification of opening position, as shown in figure 5, hole 3 of skimming is including spaced multiple along the length direction of flue 1.

For example, the quantity for taking off cinder hole can be 1 to 3, but it is not limited to 3.Specifically, the two neighboring cinder hole taken off Distance can be 300-1500mm.Wherein, the determination of amount principle for taking off cinder hole is according to the loose dust stratification device of industrial kiln Enter with industrial kiln dust exhaust apparatus depending on the scope of activities in flue.

The maximum length of cinder hole, the size of Breadth Maximum are taken off between 100-300mm × 100-300mm, takes off cinder hole The design principle of maximum length and greatest width dimension is according to the loose dust stratification device of above-mentioned industrial kiln and industrial kiln The size of the outline of dust exhaust apparatus.For example, in industrial kiln dust exhaust apparatus, can be according to the external diameter size of endothermic tube 30 It is determined that.The diameter of the endothermic tube 30 is not limited within 300mm typically within 300mm.The above-mentioned loose product of industrial kiln The design principle of the size of the outline of apparatus for ash and industrial kiln dust exhaust apparatus be the loose dust stratification device of industrial kiln and The power size of industrial kiln dust exhaust apparatus, dust stratification vibrated loose decomposition after granular size and endothermic tube refrigerating capacity Etc. factor.

Further to ensure the melting process of the product quality of glass substrate and kiln, the area in hole 3 of skimming and accumulation of heat The ratio of the cross-sectional area of room 2 is 1%-3%.

It is each in regenerator to be removed using the loose dust stratification device of above-mentioned industrial kiln and industrial kiln dust exhaust apparatus The dust stratification of individual opening position, as shown in figure 5, hole 3 of skimming is including spaced multiple along the length direction of regenerator 2.

To adapt to the shape of the outline of the loose dust stratification device of above-mentioned industrial kiln and industrial kiln dust exhaust apparatus, take off Cinder hole 3 is formed as circular hole or square hole.

Further, be formed as the good product quality of glass substrate of guarantee and the melting process of kiln, hole 3 of skimming Square hole, the square length of side are 100mm to 400mm.

Because the dust stratification at the flue shutter 6 of flue 1 is accumulated more, the hole 3 of skimming on flue 1 is close to flue shutter 6 Set.

In addition, as shown in figure 4, above-mentioned flue 1 can include the flue collector 1a that is connected with chimney 5, and with flue collector 1a Multiple by-pass flue 1b of connection.That is, taking off cinder hole can be formed on flue collector 1a and by-pass flue 1b simultaneously.

Therefore, when clearing up the high temperature bonding dust stratification in Industrial Stoves, door of skimming is first turned on, industrial kiln is loose Dust stratification device through taking off cinder hole, and by the loose dust stratification device by high temperature bond dust stratification it is loose be particle dust.Then by work Industry kiln is taken out from taking off in cinder hole with loose dust stratification device, and the loose dust stratification device of industrial kiln is passed through through cinder hole is taken off Particle dust is pumped in dust stratification collecting box 600 by the loose dust stratification device of industrial kiln.When from one of Industrial Stoves Take off in cinder hole after cleaning out supply and back oil pipe dust stratification, close door of skimming.Then open close to another door of skimming, repeat it is above-mentioned Operation, you can in the case where having little influence on burning process and glass substrate quality, quickly clear up Industrial Stoves safely Interior high-temperature deposition.
