Efficient in-furnace denitration spraying device of waste incineration waste heat boiler

The utility model relates to an ancillary facility of a waste incineration device. According to the technical scheme, the efficient in-furnace denitration spraying device of the waste incineration waste heat boiler comprises a DCS (Distributed Control System); the device is characterized by further comprising a plurality of acoustic temperature measuring devices and a plurality of atomization spraying units which are arranged in a first flue gas channel and a second flue gas channel of the waste incineration waste heat boiler and electrically communicated with the DCS, so that an optimal temperature field suitable for reducing agent reaction of the SNCR denitration system is captured in the waste heat boiler, and reducing agent spraying is carried out. The spraying device has the characteristics of reasonable structure, no occupation of redundant space, reliable operation and high denitration efficiency. 本实用新型涉及一种垃圾焚烧装置的附属设施。技术方案是：一种高效的垃圾焚烧余热锅炉炉内脱硝喷射装置，包括DCS系统；其特征在于：该装置还包括布置在垃圾焚烧余热锅炉第一烟气通道与第二烟气通道且电连通DCS系统的多个声
