Sludge sintered brick and preparation process thereof
The invention discloses a sludge sintered brick and a preparation process thereof. The preparation process comprises the following steps: preparing the following raw materials in parts by mass: 70-90 parts of sludge, 10-20 parts of fly ash, 15-30 parts of high-aluminum clinker and 3-5 parts of fuel; uniformly mixing and stirring the deodorized sludge and fly ash to form a mixture I with the sludge water content of 28-33%; uniformly mixing and stirring the mixture I and the high-aluminum clinker to form a mixture II; the second mixture and fuel are mixed and stirred to be uniform, then crushed through a crusher and screened through a roller screen machine, and biochar mud with the water content being 10%-15% is formed; the preparation method comprises the following steps: mixing 15-30 parts by mass of charcoal mud, 20-45 parts by mass of coal gangue, 10-30 parts by mass of building waste soil and 5-15 parts by mass of shale, adding 5-15 parts by mass of water, stirring, crushing, screening and aging to obtain a blank; performing extrusion molding on the blank to prepare a green brick, drying the green brick, and sintering the green brick in a tunnel kiln to form a sintered brick; the charcoal mud is used for replacing part of coal gangue, the overall cost is low, the sludge utilization rate is high, and the brick quality is good.
本发明公开了一种污泥烧结砖及其制备工艺，包括以下步骤：按照质量份数准备以下原料：污泥70～90份，粉煤灰10～20份，高铝熟料15～30份，燃料3～5份；除臭后的污泥与粉煤灰混合搅拌均匀，形成污泥含水率为28％～33％的混合料一；将混合料一与高铝熟料混合搅拌均匀，形成混合料二；将混合料二与燃料混合搅拌均匀，再通过破碎机破碎，之后通过滚筛机过筛，形成含水率为10％～15％的生物炭泥；将生物炭泥、煤矸石、建筑废弃土和页岩按质量份数15～30份、20～45份、10～30份和5～15份进行混合，再加质量份数为5～15份的水搅拌，之后破碎，筛分和陈化后得到坯料；将坯料挤出成型制成砖坯，砖坯烘干后送至隧道窑内烧结，形成烧结砖；利用生物炭泥代替部分煤矸石，整体成本低、污泥利用率大且砖质量好。
