Description

Technical Field

[0001] The utility model relates to the technical field of waste hydrogen combustion devices, in particular to a waste hydrogen combustion device with a heat recovery function for a full hydrogen gas bell-type furnace. Background Art

[0002] In recent years, with the increasing market demand for bright annealed plates and strips of ferrous and non-ferrous metals, these plates and strips are often delivered in the form of coils during the production process. Their heat treatment has long relied mainly on hood annealing furnaces. The most advanced technology is to use full hydrogen strong convection hood furnaces for treatment. During the annealing process, hydrogen needs to be introduced to protect the material from oxidation, making the surface bright and improving the heat transfer efficiency, thereby improving the annealing capacity, ensuring the uniformity of the furnace temperature, and ensuring the mechanical properties of the steel coil.

[0003] However, during the heating process, hydrogen will be discharged into the atmosphere together with other harmful substances such as residual emulsion and oil fume in the steel coil, which will produce high-temperature waste hydrogen. Not only will the thermal energy resources be easily wasted, but it will also pollute the air environment. At the same time, the emulsion and oxides brought by the cold-rolled coil will produce oil fume, water vapor, dust and other harmful substances during the annealing process, which will be discharged into the air along with the waste hydrogen, causing pollution to the air environment. To this end, we provide a waste hydrogen combustion device with heat recovery function for a full hydrogen gas bell-type furnace to solve the above problems. Utility Model Content
