Description

Technical Field

[0001] The invention relates to the technical field of environmental protection processing equipment, in particular to a novel energy-saving and environmentally friendly furnace. Background Art

[0002] During the combustion process in the furnace, the material is placed in the hollow cavity of the furnace body, and a flame injection device is embedded in the wall of the furnace body. During use, the heating efficiency of the material is higher only when the temperature in the furnace is kept within a certain range. Whether the temperature in the furnace is stable depends on whether the combustion is sufficient and the sealing of the furnace body. In order to facilitate loading, existing industrial kilns mostly use a trolley-type structure, which easily causes heat loss at the bottom of the furnace body and the sealing door. For sufficient combustion, when the gas is fully mixed, the combustion efficiency is higher. However, the existing equipment cannot achieve uniform heat distribution when dissipating heat, resulting in local heat deficiency, which in turn prolongs the overall heating time of the equipment.
