Step illustrates, but these embodiments absolutely not limit the utility model.
The big arch I of oxy-fuel combustion glass melting furnace provided by the utility model is made of more than ten section arch, single-unit arch as shown in Fig. 2,
Including big arch arch brick 1, it is located at the outermost arch foot brick 2 of big arch.Two pieces of arch foot bricks 2 and tens of pieces big arch arch brick 1 on the outside of big arch
One ring independence arch, respectively A column, B column, B column, C column are constituted using laid dry mode.Big arch arch brick 1 is in centre, big arch arch foot brick 2
In big arch two sides.A column, B column, C arrange this Fourth Ring independence arch arranged in parallel (before being below Fig. 2, top is rear) along the longitudinal direction, group
Cheng Yijie arch.Tens section arch are combined, and it is whole to constitute the big arch of oxy-fuel combustion glass melting furnace.Before being constituted in single-unit arch
The big arch arch brick 1 of both ends independence arch (A column and C column) and the big arch arch brick 1 for constituting intermediate independent arch (B column) are different (see Fig. 3 institute afterwards
Show), the big arch arch brick 1 for constituting intermediate independent arch (B column) is all the same, therefore the independent arch being located among single-unit arch is referred to as B
Column, the independent arch positioned at single-unit arch rear and front end are referred to as A column and C column.
Wherein, 1 front of big arch arch brick of B column is up big and down small wedge shape, as shown in figure 4, in big 1 microcephaly bottom surface of arch arch brick
It is semicircular fin 3 that portion's through-thickness, which is equipped with a section, and the section radius of fin is 40-50mm, length and big arch arch
1 thickness of brick is isometric, as shown in Figure 5.1 major part front and back of big arch arch brick, two top edge is set as lead angle, i.e. top surface and front, top
Face is connect with the back side by an inclined-plane 4, and the length on inclined-plane 4 is identical as the width dimensions of big 1 front and back of arch arch brick, inclined-plane 4
Angle with big 1 upper surface of arch arch brick is 45 °, and height of 4 lower end of inclined-plane away from big 1 upper surface of arch arch brick is 50-80mm.
1 front of big arch arch brick of A column and C column is also up big and down small wedge shape, along thickness in the middle part of big 1 microcephaly bottom surface of arch arch brick
It is semicircular fin 3 that direction, which is equipped with a section, and the section radius of fin is 40-50mm, length and big 1 thickness of arch arch brick etc.
It is long, as shown in Figure 5.The big 1 positive top edge of major part of arch arch brick is lead angle, i.e., top surface is connect with front by an inclined-plane 4, inclined-plane
4 length is identical as the positive width dimensions of big arch arch brick 1, and the angle of inclined-plane 4 and big 1 upper surface of arch arch brick is 45 °, inclined-plane 4
Height of the lower end away from big 1 upper surface of arch arch brick is 50-80mm.The top edge at the big 1 major part back side of arch arch brick is a groove, groove
Section is right angle, and length is identical as the width dimensions at big 1 back side of arch arch brick, and the width of groove is 150-200mm, and depth is
75-100mm。
When the big arch arch brick 1 of adjacent two column is built together, top surface forms a V-type space, height 50-80mm, such as Fig. 3
Shown, V-type space is covered with one in the lid seam brick 5 of up-side down triangle.Vapor and alkali steam along big arch inner surface vertical masonry joint to
When penetrating outside, is stopped by lid seam brick 5, can be also sealed with fire clay in big arch outer surface in engineering, the presence of lid seam brick 5,
Also the sealing effect of fire clay is strengthened, while ensure that fire clay is not fallen into melting tank VI, pollutes glass metal.Every section arch it

(a variety of epipastic mineral raw materials and industrial chemicals mix) melt under the high-temperature gas effect that fuel combustion generates to be formed
Liquid glass, fuel combustion generate CO2And H2O(g).Glass raw material generates in fusion process flies material, is taken to greatly by high-temperature gas
1 inner surface of arch arch brick forms drop in conjunction with the vapor that fuel combustion generates, and drop is under the effect of gravity along big arch arc
Inner surface flow down, the drop of flow down is adsorbed on lug boss by the semi-circular boss 3 on big arch arch brick 1 at this time
3 surroundings of position, with the increase of winged material, the drop for being adsorbed on 3 surrounding of boss also increases, and the gravity suffered by the drop is greater than absorption
When power, drop can vertically be fallen into melting tank VI, and fusing forms liquid glass at high temperature, so that drop be prevented to flow to fusing
Portion's breastwork IV causes to corrode to it.
Meanwhile the alkali vapor that the glass raw material in melting tank VI generates during fusing forms liquid glass is fired with fuel
The vapor mixing generated is burnt, when the gas with strong corrosive of mixing rises to big arch inner surface, lid seam brick 5 is stopped
Mixed gas invades the gap of the big arch arch brick 1 of adjacent two column, ensure that entire big arch has intact sealing performance, to mitigate
The erosion of vapor and alkali vapor to kiln body, improves the service life of oxy-fuel combustion glass melting furnace.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
Into the content that also should be regarded as the utility model with retouching.
