烟气净化系统
摘要：
本实用新型涉及碱生产燃煤炉烟气处理技术领域，公开了一种烟气净化系统，包括脱硝装置和脱硫装置，所述脱硝装置包括烟气通道，所述烟气通道与余热锅炉连通，所述余热锅炉的出气口与脱硝反应器的进气口连通；所述脱硫装置包括脱硫塔，所述脱硫塔的进气口与所述脱硝反应器的出气口连接，所述脱硫塔的出气口与烟囱连接。烟气通道与氨水蒸发槽连通，通过烟气的余热使氨水从液态转换成气态，脱硝反应器内设置至少一层设有催化剂的反应板，保证烟气完全脱硝；脱硫塔内设置至少一层碱性脱硫液喷淋机构保证脱硫效果，除雾机构进一步对脱硫后的烟气进行净化，保证进入烟囱的烟气完全净化，安全环保。
摘要（英）：

The utility model relates to the technical field of alkali production coal-fired furnace flue gas treatment, and discloses a flue gas purification system which comprises a denitration device and a desulfurization device, the denitration device comprises a flue gas channel, the flue gas channel is communicated with a waste heat boiler, and a gas outlet of the waste heat boiler is communicated witha gas inlet of a denitration reactor; the desulfurization device comprises a desulfurization tower, a gas inlet of the desulfurization tower is connected with a gas outlet of the denitration reactor,and a gas outlet of the desulfurization tower is connected with a chimney. The flue gas channel is communicated with the ammonia water evaporation tank, ammonia water is converted into a gas state from a liquid state through waste heat of flue gas, and at least one layer of reaction plate with a catalyst is arranged in the denitration reactor, so that complete denitration of the flue gas is guaranteed; at least one layer of alkaline desulfurization liquid spraying mechanism is arranged in the desulfurization tower to guarantee the desulfurization effect, the demisting mechanism further purifies the desulfurized flue gas, it is guaranteed that the flue gas entering the chimney is completely purified, and safety and environmental protection are achieved.
