Flue gas purification system for medical waste incineration

The utility model relates to a flue gas purification system for medical waste incineration, which comprises a dry SNCR (selective non-catalytic reduction) denitration device arranged in an incinerator, and a quenching deacidification purification device, an activated carbon injection device and a cloth bag dust removal device which are sequentially connected to a flue gas outlet of the incinerator, the system has the beneficial effects that denitration is carried out through the dry-method SNCR denitration device, deacidification is carried out through the quenching deacidification purification device, solid particulate matters of the activated carbon spraying device and the bag-type dust removal device are removed, and further deacidification is carried out through the alkali washing device; and through multiple purification and removal, the purification effect of the flue gas is greatly improved, and the up-to-standard emission of the flue gas can be better met. 本实用新型涉及一种医疗垃圾焚烧的烟气净化系统，包括设于焚烧炉内的干法SNCR脱硝装置，以及
