Chromium corundum brick for sulfur recovery acid gas incinerator and preparation process of chromium corundum brick
The invention discloses a chrome corundum brick for a sulfur recovery acid gas incinerator and a preparation process thereof. The chrome corundum brick for the sulfur recovery acid gas incinerator is prepared by the steps that chromic oxide, fused white corundum, calcined alpha-aluminum oxide micro powder, kaolin, zircon sand, flint clay, andalusite micro powder and the like are used as main materials, aluminum dihydrogen phosphate and water are added, the materials are mixed to be uniform, a mixture is pressed and shaped, and fired into refractory bricks at high temperature; the long service life is met, meanwhile, acid corrosion generated by burning sulfur-containing gas is obviously resisted, a metal cylinder is protected, and the cost performance is extremely high. The chrome corundum brick for the sulfur recovery acid gas incinerator is used in the incinerator, effectively overcomes the defects of poor acid gas corrosion resistance, low refractoriness and poor thermal shock resistance of a common corundum refractory brick, and plays a positive role in long-period stable operation of equipment.
本发明公开了一种硫磺回收酸性气焚烧炉用铬刚玉砖及其制备工艺，本发明硫磺回收酸性气焚烧炉用铬刚玉砖是由氧化铬、电熔白刚玉、煅烧α‑氧化铝微粉、高岭土、锆英砂、焦宝石、红柱石微粉等为主料，外加双氢磷酸铝和水，混合均匀后，经压制成型后经高温烧制成耐火砖，在满足长寿的同时，明显抵抗由焚烧含硫气体产生的酸性腐蚀，保护金属筒体，性价比极高。本发明硫磺回收酸性气焚烧炉用铬刚玉砖在焚烧炉内使用，有效解决了普通刚玉耐火砖抗酸性气体腐蚀能力差，耐火度较低，热震稳定性不好的缺点，对设备长周期稳定运行起到十分积极的作用。
