Description

Industrial furnace and furnace wall plate lining structure thereof Technical Field The utility model relates to the technical field of thermal equipment, in particular to a furnace wall plate lining structure. In addition, the utility model also provides an industrial furnace comprising the furnace wall plate lining structure. Background In order to ensure the normal operation of the heat exchange process in the furnace and to protect the furnace wall plate and the internal structure, the industrial furnace is generally provided with a lining structure, and the lining is mostly fixed on the inner surface of the furnace wall plate through anchor nails. Because the anchor nail is mostly made of metal materials, the heat conduction is easy, and dew point corrosion resistant paint is usually required to be smeared to protect the anchor nail and the furnace wall plate, so that the heat conduction performance of the anchor nail is reduced, the corrosion of the anchor nail caused by a high-temperature environment is further reduced, and the service lives of the anchor nail and the lining are prolonged. In the prior art, in order to meet the heat insulation requirement, the dew point corrosion prevention coating outside the anchor nails and the furnace wallboard needs to be coated by 2-3mm, but is limited by the thick material of the dew point corrosion prevention coating, and the thickness requirement can be met only by coating for many times, so that the coating efficiency is low. Meanwhile, the space between the anchoring nails on the furnace wall plate is usually smaller, so that the coating efficiency of the dew point corrosion-resistant coating is further reduced, the coating is easy to be uneven, and the heat preservation effect of the furnace wall plate lining structure is affected. In summary, how to construct a lining structure with convenient construction and good heat preservation effect is a problem to be solved by those skilled in the art.
