Description

TECHNICAL FIELD

[0001] The utility model relates to glass melting furnace structure technical field, especially a kind of partition wall structure of transverse flame glass melting furnace regenerator. BACKGROUND

[0002] Regenerator is the waste heat utilization equipment of transverse flame glass melting furnace, and is the important component of transverse flame flat glass melting furnace structure, as the carrier of heat storage, its structure form and shape have great influence on heat storage capacity, and the structure form of the commonly used checker bricks has three kinds: strip brick, cylindrical brick and cross-shaped brick.

[0003] Transverse flame glass melting furnace generally has multiple pairs of small furnaces, and the position of small furnace before hot spot is more prone to ablation, blockage or collapse due to its close distance to feeding port, while the checker bricks of regenerator after hot spot are less eroded than the first few pairs of small furnaces, so by considering the investment cost, it can be confirmed that cross-shaped checker bricks are used for small furnaces at hot spot position and before it, and cylindrical bricks are used for checker bricks of regenerator after hot spot, which can not only exert the characteristics of cross-shaped checker bricks such as erosion resistance, long service life and high heat storage, but also reduce the investment cost of melting furnace.

[0004] As the carrier of waste heat utilization of regenerator, checker bricks not only need to ensure that flue gas can smoothly pass through the cavity of checker bricks and accumulate heat in the brick body, but also need to ensure that when combustion-supporting gas passes through the checker bricks, it can heat the combustion-supporting air to improve the temperature of combustion-supporting air and achieve the effect of waste heat utilization. For this purpose, checker bricks need to have a support body in the regenerator, which is called furnace strip arch in the glass melting furnace. The furnace strip arch is the arch that bears the largest distributed load among all the arches of the entire glass melting furnace, and its stability is the prerequisite for the safe operation of the regenerator.

[0005] The furnace strip arch is composed of multiple transverse and multiple longitudinal circular-arc-shaped small arches, and each pair of small arch corresponding to each small furnace in the whole furnace is usually connected in back-to-back form with its arch foot brick, so as to ensure that each pair of arch bears force and cancels each other out, and the structure of the furnace strip arch is the most stable. Therefore, in the same melting furnace, only one type of checker brick is usually selected, the size of the checker brick grid hole is fixed, and the corresponding interval distance of the furnace strip arch is also fixed, so that the longitudinal arch foot can be connected in back-to-back form. If two types of checker bricks are selected, the size of the grid hole cannot be unified, so the interval distance of the furnace strip arch corresponding to the checker brick is also different. In order to ensure that the airflow is not blocked at the position of the furnace strip arch, the arch foot brick on the wall where the type of checker brick is changed cannot be connected in back-to-back form, which will affect the structural strength of the entire furnace strip arch and thus affect the safe operation of the regenerator.

[0006] According to the search, the Chinese utility model patent with the publication number CN205635350U discloses a whole partition wall structure of a regenerator of a fuel-fired glass furnace. The application uses fused zirconia corundum brick as the partition wall material, but since the glass phase content in the fused zirconia corundum brick is high, the glass phase will gradually precipitate and even be lost at high temperature, so when the glass phase is not filled between the crystal grains, the strength of the fused zirconia corundum brick will decrease; in addition, since the temperature between the two small furnaces is higher than that on both sides of the small furnace, the amount of glass phase lost at this position will be more, resulting in poorer strength, so the middle partition wall and the small furnace arch foot are more prone to collapse.

[0029] The technical scheme of the present application is further described in detail below in combination with the drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0030] Embodiment 1

[0031] Referring to the drawings, Figures 1-8 The present application provides a partition wall structure of a transverse flame glass melting furnace regenerator, which comprises four hot point front regenerators (1#-4#) and two hot point rear regenerators (5# and 6#). The hot point front regenerators and the hot point rear regenerators are arranged in sequence, i.e., the regenerators 1#-6# are arranged in sequence from left to right according to the numbers, and a partition wall 1 is arranged between adjacent hot point front regenerators and hot point rear regenerators, i.e., the partition wall 1 is arranged between the regenerators 4# and 5#.

[0032] The partition wall 1 is composed of a framework 4 inside and a heat-resistant main body 5 outside. The framework 4 is a reinforced cage, and the maximum heat-resistant temperature of the steel material of the reinforced cage is 1000℃.

[0033] Preferably, the length and height of the framework 4 are respectively 80-100mm smaller than the length and height of the partition wall 1. The height of the framework 4 is the height H in the formula. Figure 6 and Figure 7 The width of the framework 4 is 100mm smaller than the distance between the cross brick checker 2 and the cylindrical brick checker 7.

[0034] Preferably, the heat-resistant main body 5 is heat-resistant concrete, and the material requirements of the heat-resistant concrete are as follows:

[0035] Composition: AL2O3: 42-48, Fe2O3: ≤1.5, CaO <8, Na2O+K2O <0.65-0.7;

[0036] Maximum heat-resistant temperature: 1400-1450℃;

[0037] 5-hour pressure resistance at 1000℃: >19N / mm2.

[0038] A cross-shaped brick grate arch 2 is provided in the heat storage chamber before the hot spot. A cross-shaped brick grate arch 2 is fixedly connected to the partition wall 1 with a cross-shaped brick grate foot brick 3, which is used to support the cross-shaped brick grate arch 2. The interior of each of the four heat storage chambers before the hot spot is provided with cross-shaped grid bricks 8, which are used to support the cross-shaped grid bricks 8.

[0039] The regenerator chamber after the hot spot is equipped with a cylindrical brick furnace grate 7. The cylindrical brick furnace grate 7 is fixedly connected to the partition wall 1 with a cylindrical furnace grate arch foot brick 6, which is used to support the cylindrical brick furnace grate 7. The regenerator chambers after the hot spot are equipped with cylindrical grid bricks 9. The cylindrical brick furnace grate 7 is used to support the cylindrical grid bricks 9.

[0040] Working principle: When the regenerator is built to the top of partition wall 1, place cross-shaped arching bricks 3 and cylindrical grate arching bricks 6 at the top position of partition wall 1 for partition walls #4 and #5, and then... Figure 4 The arch bricks are evenly placed at intervals L2 and L4 as shown. Then, the pre-made frame 4 is placed in the frame. The template is erected according to the shape and structure of the partition wall 1. The mixed heat-resistant concrete is poured into the erected template and tamped evenly. After the heat-resistant concrete has solidified, the template is removed to form the partition wall 1. The partition wall 1 will form a whole heat-resistant reinforced concrete beam. The walls where the arch bricks are located in other parts are still constructed with normal bricks.

[0041] Based on the height of the checker bricks in the regenerator chamber, the compressive stress borne by the arch feet of two adjacent grate arches can be calculated, and thus the size of the reinforcing bars for the steel cage and the spacing of the stirrups can be calculated. Based on the length and width of partition wall 1 and the spacing between the two grate arches, the length, width, and height of the steel cage can be determined.

[0042] Since the temperature of the space where the arch bricks are located is between 500-800℃, while the temperature inside partition wall 1 is around 600℃ for a long time, and the steel cage is embedded in the wall, heat-resistant steel is required to make the steel cage. When construction reaches the arch bricks, the prepared steel cage is placed in advance on the partition wall in the middle of the arch bricks, and then heat-resistant concrete is poured. This heat-resistant reinforced concrete wall bears the arch pressure that cannot be offset on both sides, ensuring that the structural strength of the grate arch is not affected.

[0043] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
