The invention relates to the technical field of building materials, in particular to a preparation method of a green low-thermal-conductivity insulating brick suitable for an outer wall, which comprises the following steps: S1, weighing industrial waste, clay, a foaming agent and reinforced fibers according to a ratio, and primarily mixing; s2, carrying out wet ball-milling treatment to obtain ball-milled slurry; s3, adding a binder and water into the ball-milled slurry, and carrying out stirring homogenization treatment to obtain homogenized slurry; s4, injecting the homogenized slurry into a mold, and molding through a compression molding process to obtain a green brick body; s5, performing low-temperature sintering treatment to obtain a sintered brick body; and S6, carrying out surface hydrophobic treatment on the sintered brick body to obtain a finished insulating brick product. According to the invention, by optimizing the raw material ratio, controlling the molding and sintering process and introducing the surface hydrophobic treatment, the coordination and unification of green raw material utilization, low thermal conductivity control and the moisture resistance of the brick body are realized.

This invention provides a negative carbon thermal circulation upgrading furnace and its application, relating to the field of industrial solid waste treatment technology. The upgrading furnace includes at least three assemblable unit modules, each comprising a furnace body, multiple horizontally inserted U-shaped pipes, an air inlet main pipe, and an exhaust main pipe. The furnace body has a rectangular cross-section, with opposing through holes on the front and rear walls. The U-shaped pipes, including U-shaped air inlet pipes and U-shaped air outlet pipes, are inserted into these through holes. The U-shaped air inlet pipes are connected to the air inlet main pipe, and the U-shaped air outlet pipes are connected to the exhaust main pipe. Based on this main body, flue gas is introduced or discharged through the horizontally inserted U-shaped pipes, enabling flexible control of material drying, internal combustion, reheating, and cooling within the furnace. This invention also provides applications of the upgrading furnace. Through modular furnace design and a high-efficiency flue gas circulation system, this invention achieves low-energy, high-value treatment of various solid wastes, ultimately achieving a negative carbon target.
