[0002] Low-temperature magnetic cracking technology uses heat energy (medical waste itself) to break the chemical bonds of medical waste (organic matter) under oxygen-deficient conditions, converting it into a fuel gas with a small molecular weight, and then completely burning (oxidizing) the fuel gas at high temperature until it meets emission standards.

[0003] Low-temperature magnetic cracking treatment technology can make up for the shortcomings of high-temperature steam treatment technology. It can not only treat infectious waste and damaging waste, but also pathological waste, pharmaceutical waste, and chemical waste (excluding medical waste with high mercury and volatile organic compound content).

[0004] In the prior art, low-temperature magnetization cracking equipment is mainly used to process some organic waste, and is equipped with a lifting device or a feeding device to feed the waste into the furnace. However, for some chemical wastes, which are generally liquid reagents, it is impossible to directly put them into the furnace through the lifting device, so it is necessary to design an injection structure so that the chemical reagent waste can be evenly put into the furnace. The chemical waste will be volatilized by heat in the furnace, and after high-temperature secondary combustion, it will be discharged through the subsequent flue gas purification system.
