Abstract

The invention relates to the field of waste heat recycling technologies, in particular to a flue gas waste heat recycling system of a fluidized bed roaster. Running systems can be preheated by a set preheater. The flue gas waste heat recycling system is provided with a steam generator and an ash removing device and is configured with connecting accessories such as corresponding valves and pipelines. The steam generator is a heat-resistant and corrosion-resistant heat pipe original component, and heat of flue gas of the fluidized bed roaster can be comprehensively recycled. Compared with an existing flue gas waste heat recycling device of a fluidized bed roaster, the flue gas waste heat recycling system has the advantages that the heat of the flue gas with high water contents, dew points and dust contents can be reliably recycled, energy can be saved, environments can be protected, the energy utilization rate can be increased, and the like.

Description

technical field [0001] The invention relates to the field of waste heat recovery, in particular to a waste heat recovery system for fluidized roaster roasting flue gas and a method for using the same. Background technique [0002] Fluidized roaster is a device for roasting sulfide minerals with solid fluidization technology, and is mainly used for roasting and desulfurization of gold-containing materials such as pyrite, zinc concentrate, and sulfur-containing gold concentrate. During the roasting process, a large amount of reaction heat is released, and the gas containing sulfur dioxide is produced for the production of sulfuric acid, and the roasted slag is used as a metallurgical raw material. Due to the different types and methods of treating sulfur-containing materials, the flue gas working conditions of fluidized roasting furnaces are also very different. Generally, the temperature at the outlet of the flue gas of the roasting furnaces that process dry sulfur-containing...
