Embodiment 1
[0019] When the oil residue is burned, only the oil residue can be burned, or carbon can be added to it and then burned, and with the different sulfur content in the oil, the amount of calcium oxide CaO added to it during desulfurization will change accordingly, so every The contents of each component in the fly ash and bottom slag formed at the second time are different. Assuming that no carbon is added when the oil residue is burned, the theoretical value of the content of each component in the burned fly ash can be known by calculation:

Embodiment 2
[0029] Add gypsum accounting for 20% of the mass of the main raw material to the main raw material, stir the main raw material and gypsum continuously to make it evenly mixed, then pour a certain amount of additive, namely dilute sulfuric acid solution, and continue stirring for 2 to 10 minutes to make the main raw material and additive Fully react, after stirring, pour the formed wet material into the mold of the brick making machine. Since the added gypsum acts as a coagulation accelerator, the initial setting time of the material is 15 minutes. Before the initial setting of the material, pass the moisture Vibration and molding of the materials make blocks of various shapes, after the initial setting of the blocks, they are demoulded and dried naturally to form gypsum blocks.
[0030] The gypsum block is characterized by a short initial setting time and high strength. The more gypsum added to the main raw material, the shorter the initial setting time, so the amount of gypsum ...
Embodiment 3
[0033] Add sand to the main raw material, wherein the quality of the sand is twice that of the main raw material. Stir the main raw material and sand continuously to make it evenly mixed, then pour a certain amount of additive, namely dilute sulfuric acid solution, and continue stirring to make the main raw material and sand The additives are fully reacted, and the wet material formed after stirring can be used as plastering mortar for the wall. The plastering mortar has high strength, similar to cement, and is not easy to crack, and its adhesion ability is stronger than cement.
[0034] Others are the same as embodiment 1.
