Embodiment 1

[0016] Embodiment 1, the high-aluminum all-ceramic spherical arch is a single-layer structure, which includes three types of bricks: arch bricks, arch foot bricks and arch core bricks. The spherical arch is supported on the bottom plate of the inner cavity of the tower, and the arch core The bricks are in the form of a cross ring, and the arch core brick is located in the center of the spherical arch. The arch brick is an italic body with an I-shaped cross-section. It is a circle composed of several arch bricks, which are arranged in a circle from the inside to the outside. The periphery of the arch core bricks forms a ring body, and wedge-shaped arch foot bricks are arranged at the junction of the last circle of arch bricks and the inner cavity of the tower. The arch bricks, arch foot bricks and arch core bricks are all made of calcined alumina, activated alumina, feldspar powder, Qingyuan porcelain clay, Fujian porcelain clay, left cloud soil and Handan soil, and are prepared...

Embodiment 2

[0025] Example 2, the high-aluminum all-ceramic spherical arch is double-layered, and it includes four brick bodies: gas distribution brick, arch brick, arch foot brick and arch core brick. The spherical arch is supported on the bottom plate of the inner cavity of the tower. The arch core brick is in the shape of a cross ring, and the arch core brick is located in the center of the spherical arch. The arch brick is an italic body with an I-shaped cross section, and a circle composed of several arch bricks is close to a circle from inside to outside. The enclosure is provided with the periphery of the arch core bricks to form a lower ring body. At the junction of the last circle of arch bricks and the inner cavity of the tower, there are wedge-shaped arch foot bricks. On the arch bricks, there is a layer of cloth. The upper ring body composed of air bricks has a plurality of grooves on the upper surface of the air bricks. The air distribution bricks, arch bricks, arch foot bric...

Abstract

The invention discloses a high alumina full ceramic ball arch, comprising following raw materials: calcined alumina, active alumina, feldspar powder, Qingyuan petuntse, Fujian petuntse, Zuoyun soil and Handan soil. The preparation method of the high alumina full ceramic ball arch comprising the following steps: firstly, adding the calcined alumina, the active alumina, the feldspar powder, the Qingyuan petuntse, the Fujian petuntse, the Zuoyun soil and the Handan soil into a globe mill in a certain proportion and evenly mixing the mixture; secondly, mixing and ball milling the mixture with dolomite; thirdly, milling with proper amount of water to form sizing agent; and finally staling, extracting, molding, drying and firing the sizing agent to obtain the high alumina full ceramic ball arch. The high alumina full ceramic ball arch greatly improves the intensity of the ball arch, can lighten the weight of the ball arch, reduces the depth of small brick body, increases the superficial area of holes in the ball arc, and increases the percentage of opening of the ball arc to 68-72%, thereby being capable of reducing flow resistance in a tower, improving air velocity, enlarging the air flow of the tower, improving the work efficiency of the tower and improving yield by more than 10%, and being good for improving the whole carrying capacity of the ball arc, enlarging the area of thrust surface in the tower, more evenly dispersing pressure in the tower and extending the service life of the ball arc.

Description

technical field [0001] The invention relates to a supporting device for industrial tower equipment, in particular to a high-aluminum all-ceramic spherical arch used in industrial drying towers and absorption towers. Background technique [0002] At present, in the chemical industry, smelting and petroleum industries, the bottom of the drying tower and absorption tower in the industrial tower equipment is equipped with a support structure with high acid and alkali resistance, thermal stability and good mechanical properties - the ball Arch, the opening ratio of the spherical arch (the ratio of the surface area of ​​the hole on the spherical arch to the total surface area of ​​the spherical arch) is an important factor affecting the working effect of the drying tower and the absorption tower. The larger the opening ratio, the smaller the flow resistance in the tower, the higher the air velocity, the lower the energy consumption, and the better the working effect of the tower e...
