Method for quickly judging fault of EC spray gun of dry dedusting system

The invention belongs to the field of environmental protection equipment, and relates to a method for quickly judging faults of an EC spray gun of a dry dust removal system, which quickly checks whether the EC spray gun has a water channel blockage fault or not in a non-stop production state, reduces the fault checking difficulty of the EC spray gun of the dust removal system, improves the checking efficiency of the EC spray gun and saves the checking and maintaining time. The production guarantee capability of the dust removal system is improved, and the dust falling capability of the dust removal system is improved. 本发明属于环保设备领域，涉及干法除尘系统EC喷枪故障快速判断的方法，在不停产的状态下快速检查EC喷枪是否发生水道堵塞故障，降低除尘系统EC喷枪故障检查难度，提高EC喷枪检查的效率，节约检维修时间；使除尘系统的生产保障能力提升，提高除尘系统降尘能力。
