Description

Technical Field

[0001] The utility model relates to the technical field of glass production, and specifically, the utility model relates to a wall structure of a regenerator. Background Art

[0002] The regenerator is an important part of a glass furnace; the function of the regenerator is to absorb and store the heat contained in the waste gas through checker bricks, and then transfer it to the combustion-supporting air, heating it to a certain temperature to enable the fuel to achieve the best combustion effect, so as to achieve the purpose of saving fuel and reducing costs; for the upper wall of the regenerator to resist the erosion of alkali vapor, magnesite bricks are generally used for masonry; the height of the regenerator of a large furnace is generally more than 10 meters. To ensure the stability of the wall structure, the wall generally uses two thicknesses of 578 mm or 694 mm and is masonry with standard bricks (specification 230×114×65); magnesite bricks have a high thermal conductivity and good heat conduction performance. To reduce the heat dissipation of the wall, the outer side of the wall is masonry with insulating bricks (thickness 114 mm or 230 mm), and the inner side of 464 mm is masonry with magnesite bricks; in this kind of regenerator structure, a large amount of magnesite bricks are used. Due to the high price of magnesite bricks, the cost of the regenerator is high; in addition, the magnesite bricks are in direct contact with the insulating bricks. Due to the good heat conduction performance of the magnesite bricks, the insulating bricks on the contact surface are easily burned out.

[0003] The applicant found through retrieval that the Chinese patent document with the publication number of 203754577U discloses a wall of a regenerator of a glass melting furnace on August 6, 2014, which includes a plurality of refractory bricks I and a plurality of refractory bricks II; a plurality of refractory bricks I arranged up and down are connected in a convex-concave snap-fit manner to form a column of refractory bricks I; a plurality of refractory bricks II arranged up and down are connected in a convex-concave snap-fit manner to form a column of refractory bricks II; two adjacent columns of refractory bricks II are bonded together to form a side wall or a partition wall, and the snap-fit seams of two adjacent columns of refractory bricks II are not on the same straight line; a plurality of columns of refractory bricks I are bonded together, a plurality of columns of refractory bricks II are bonded together, or a plurality of columns of refractory bricks I and a plurality of columns of refractory bricks II are bonded together to form a target wall or a partition wall, and the snap-fit seams of two adjacent columns of refractory bricks are not on the same straight line; this device also cannot solve the above problems.

[0017] 1. The inner wall of the present device uses magnesia bricks with strong thermal conductivity; the outer wall uses insulating bricks; the refractoriness and thermal conductivity of the middle wall are both lower than those of the inner wall; thus, a reasonable temperature gradient that gradually decreases is formed from the inside to the outside by the three-layer walls; effectively avoiding the situation that the inner wall directly contacts the outer wall, resulting in the burning of the insulating bricks of the outer wall and the decline of the heat preservation effect; at the same time, reducing the overall thermal conductivity of the wall, reducing the heat dissipation of the wall, and improving the heat storage efficiency.

[0030] Figure 1 The shown wall structure of the regenerator chamber includes an inner wall and an outer wall; a middle wall is provided between the inner wall and the outer wall.

[0031] The setting of the middle wall forms a reasonable temperature gradient that gradually decreases from the inside to the outside for the three layers of walls; effectively avoids the situation where the inner wall directly contacts the outer wall, resulting in the burnout of the insulating bricks on the outer wall and a decrease in the insulation effect; at the same time, reduces the overall thermal conductivity of the wall, reduces heat dissipation of the wall, and improves the heat storage efficiency.

[0032] The inner wall includes a first inner brick 1 and a second inner brick 2; the second inner brick 2 is arranged between adjacent first inner bricks 1.

[0033] The inner wall is arranged near the inside of the glass melting furnace; both the first inner brick 1 and the second inner brick 2 are magnesite bricks, with the same refractoriness, thermal conductivity and single brick size, but due to their vertical arrangement, the thickness of the wall formed by combined masonry is different; the end faces of the first inner brick 1 and the second inner brick 2 on the side close to the inside of the glass melting furnace are flush; the end of the second inner brick 2 on the side close to the middle wall extends out for interlocking masonry with the middle wall.

[0034] The first inner brick 1 includes an inner vertical brick 101; the second inner brick 2 includes an inner vertical brick 101 and an inner horizontal brick 102; the inner horizontal brick 102 is arranged on the side of the inner vertical brick 101 away from the middle wall and is perpendicular to the inner vertical brick 101.

[0035] The second inner brick 2 includes an inner vertical brick 101 and an inner horizontal brick 102 arranged vertically; the inner horizontal brick 102 is arranged on the side of the inner wall close to the inside of the furnace; the inner vertical brick 101 extends out from between the first inner bricks 1 to connect with the middle wall.

[0036] The middle wall includes a first middle brick 3 and a second middle brick 4; the second middle brick 4 is arranged between adjacent first middle bricks 3.

[0037] Both the first middle brick 3 and the second middle brick 4 are clay bricks, with the same refractoriness and thermal conductivity but different sizes; the first middle brick 3 and the second middle brick 4 are interlaced for masonry.

[0038] A first interlocking groove 103 is arranged between adjacent second inner bricks 2; the end of the first middle brick 3 is arranged in the first interlocking groove 103; a second interlocking groove 301 is arranged between adjacent first middle bricks 3; the end of the second inner brick 2 is arranged in the second interlocking groove 301.

[0039] The second middle brick 4 is perpendicular to the first middle brick 3, and the thickness of the wall formed by the second middle brick 4 is half of the thickness of the wall formed by the first middle brick 3; both the second middle brick 4 and the second interlocking groove 301 are arranged between adjacent first middle bricks 3; the second middle brick 4 is arranged on the side close to the outer wall; the second interlocking groove 301 is close to the inner wall; the end of the second inner brick 2 is inserted into the second interlocking groove 301.

[0041] The specification of the anchoring plate brick 104 is 345×114×65 or 460×114×65; the length of the anchoring plate brick 104 is equal to that of the second inner layer brick 2; the anchoring plate brick 104 can strengthen the overall structure of the middle wall and the inner wall and enhance the connection strength between the two.

[0042] The first middle layer brick 3 includes middle vertical bricks 302; the second middle layer brick 4 includes middle horizontal bricks 303; the middle vertical bricks 302 are vertically arranged with the middle horizontal bricks 303.

[0043] The second middle layer brick 4 has the same length as the first middle layer brick 3 and they are vertically arranged; it is convenient to set the second biting groove 301 and can realize the layer-by-layer biting between the middle wall and the inner wall.
