Description

一种利用高温烟气余热的方法和装置 技术领域  Method and device for utilizing high temperature flue gas waste heat
本发明属于能源再利用技术领域，特别涉及一种利用活性焦制造过程 中产生的高温烟气余热的方法。  The invention belongs to the technical field of energy reuse, and particularly relates to a method for utilizing high temperature flue gas residual heat generated in an active coke manufacturing process.
本发明还涉及用于实现上述方法的装置。 背景技术  The invention also relates to an apparatus for implementing the above method. Background technique
活性焦制造过程中， 最高温度可达 900 °C以上， 因此活性焦制备设备 内排出的烟气温度也非常高， 最高时可达 700°C以上。 从活性焦制造设备 排出的活性焦温度在 600 °C以上。  In the process of producing activated coke, the maximum temperature can reach above 900 °C, so the temperature of the flue gas discharged from the active coke preparation equipment is also very high, up to 700 °C. The active coke temperature discharged from the activated coke manufacturing equipment is above 600 °C.
活性焦制造过程中，在最后的活化阶段需要输入活化气体进行活化反 应， 活化气体通常采用蒸汽、 二氧化碳或蒸汽与二氧化碳混合气体， 而且 蒸汽须加热达到 400°C以上才能够有效地进行活化反应。  In the active coke manufacturing process, an activation gas is required to be activated in the final activation stage. The activating gas is usually a mixture of steam, carbon dioxide or steam and carbon dioxide, and the steam must be heated above 400 °C to effectively carry out the activation reaction.
从活性焦的制造工艺可以看出， 一方面活性焦在制造过程， 高温烟气 和高温活性焦中含大量的热能， 如果不进行回收利用， 一方面造成很大的 热能损失， 同时对环境造成热污染； 另一方面在活性焦制造的最后活化阶 段， 又需要输入蒸汽、对蒸汽进行加热， 而生产蒸汽和对蒸汽进行加热又 需要消耗热量。 .  It can be seen from the manufacturing process of activated coke that on the one hand, active coke contains a large amount of heat energy in the manufacturing process, high-temperature flue gas and high-temperature activated coke. If it is not recycled, it will cause a great loss of heat energy and cause environmental damage. Thermal pollution; on the other hand, in the final activation stage of active coke production, steam is required to be input and steam is heated, and heat generation is required to produce steam and heat the steam. .
能否将活性焦制造过程中排出的高温烟气和高温活性焦中所含的热 量进行回收利用， 将热能转化为蒸汽收集、 蓄存起来， 在活性焦制造的最 后活化阶段， 将蓄存的蒸汽做为活化所需的蒸汽； 用高温烟气对蒸汽进行 加热， 以满足活化反应对蒸汽温度的要求。不但可以节约能源， 降低活性 焦的制造成本， 而且避免高温烟气对周围环境造成热污染。  Can the high-temperature flue gas discharged from the activated coke manufacturing process and the heat contained in the high-temperature activated coke be recycled, and the thermal energy can be converted into steam for collection and storage, and will be stored in the final activation stage of the activated coke manufacturing process. Steam is used as steam for activation; steam is heated with high temperature flue gas to meet the steam temperature requirements of the activation reaction. It not only saves energy, reduces the manufacturing cost of activated coke, but also avoids thermal pollution of high temperature flue gas to the surrounding environment.
然而对活性焦制造过程中，高温烟气和高温活性焦中所含的热能进行 收集、 蓄存、 利用的方法和装置至今未见报道。 发明内容  However, methods and devices for collecting, storing, and utilizing the heat energy contained in high-temperature flue gas and high-temperature activated coke during the production process of activated coke have not been reported so far.
