The utility model relates to environment-friendly clean-incinerating low-emission atmospheric environmental protection equipment, in particular to an environment-friendly dust-collecting cleaning incinerator for combustible waste batteries. Vertical grates are arranged in a hearth, spaces between the vertical grates increase gradually from top to bottom, a supporting feeding slide is mounted above the top vertical grate, a flue gas convection box is mounted at the top of an incinerator body, a waste battery feeder is arranged on the lower side of the flue gas convection box, a flue gas mixer is mounted on the upper face of the flue gas convection box and communicated with a flue gas purifier through a flue gas dust collector, the flue gas purifier is of a multi-inverted-pot structure, a vertical exhaust chimney communicated with the structure is mounted on the upper portion of the flue gas purifier, the flue gas purifier is communicated with a liquification incinerator through an exhaust induced draft ventilation pipe. The environment-friendly dust-collecting cleaning incinerator is suitable for clean incineration for cleaning combustible waste batteries in big cities, counties and countryside villages and towns, is clean-incinerating dust-collecting environmental protection equipment for treatment of cities, counties and countryside villages and towns, can incinerate one to ten tons of waste batteries per day, can control purification and emission reduction of waste gas produced by the incinerated waste batteries, and can collect and recycle carbon dust of incineration.
