Multifunctional dry denitration method and device

The invention aims to provide a multifunctional dry-process denitration method and device, and belongs to the technical field of denitration, dry-process denitration is a method for carrying out reduction treatment on NOx through the dry-process denitration device by using a selective non-catalytic reduction reaction, taking a solid polymer denitration agent as a reducing agent and utilizing the characteristics that polymers are rapidly cracked and gasified when encountering heat. The method strictly complies with the principle of'material balance ', and can adapt to the temperature requirements of various fuels and different types of hearths. The activating auxiliary agent is accurately added into the high-molecular denitration agent, so that the requirements of organic groups at different temperatures are met, and the effect of enhancing the reducibility is achieved. 本发明的目的在于提供一种多功能干法脱硝方法和装置，属于脱硝技术领域，本发明的干法脱硝是选择性非催化还原反应，以固态高分子脱硝剂为还原剂，利用高分子遇热迅速裂解、气化的特性，通过干法脱硝装置，对NOx进行还原处理的方法。该方法严格遵守"物料平衡"的原则，可适应多种燃料、不同类型炉膛温度
