Aluminum ash brick and preparation process thereof
The invention discloses an aluminum ash brick and a preparation process thereof.The preparation process comprises the steps that domestic sludge, secondary aluminum ash and squeezed mud are mixed and stirred to inhibit the hydrolysis reaction of aluminum oxide in the secondary aluminum ash to generate ammonia gas, then hammered shale is added, the adsorption capacity of the shale is utilized, volatilization of the ammonia gas generated by the secondary aluminum ash can be prevented, the environment is effectively protected, and the production cost is reduced. And the aging time is shortened to be within 12 h, the raw materials can be prevented from reacting before roasting, it is ensured that the prepared brick is environmentally friendly and harmless, the quality is high, the brick quality standard is met, and in the machining process of the technology, generated waste gas meets the atmospheric pollutant emission standard.
本发明公开了一种铝灰砖块及其制备工艺，其中，首先将生活污泥、二次铝灰、压榨泥混合搅拌，以抑制二次铝灰中的氧化铝水解反应产生氨气，然后加入锤碎后的页岩，利用页岩的吸附能力，可防止二次铝灰产生的氨气挥发，有效保护环境，再将陈化时间缩短为12h内，可防止原料在焙烧前发生反应，以确保制得的砖块环保无害，且质量高，符合砖块质量标准，且上述工艺加工过程中，产生的废气符合大气污染物排放标准。
