LIME SLURRY SPRAY SYSTEM FOR TREATING FLUE GAS OF GARBAGE INCINERATION POWER PLANT

摘要

A lime slurry spray system for treating flue gas of a garbage incineration power plant, comprising a clean water conveying pipeline, a lime slurry conveying pipeline, and a compressed air conveying pipeline. An inlet of the clean water conveying pipeline is connected to a clean water tank (1A); an inlet of the lime slurry conveying pipeline is connected to a lime slurry tank (2A); outlets of the clean water conveying pipeline, the lime slurry conveying pipeline, and the compressed air conveying pipeline are respectively connected to corresponding interfaces of a spray gun (3A); the inlet of the clean water conveying pipeline is communicated with the inlet of the lime slurry conveying pipeline by means of a bypass (4); a valve (6) is provided in each pipeline. An acid liquor washing device is also provided; the acid liquor washing device comprises an acid liquor washing pipeline and an acid liquor tank (5A); the acid liquor washing pipeline conveys acid liquor from the acid liquor tank (5A) to a long-distance main slurry path (2.1B) and a long-distance spare slurry path (2.2B) for washing same; then the acid liquor flows back to the acid liquor tank (5A).
