The invention discloses a sintering flue gas desulfurization and denitrification waste heat utilization device in the field of desulfurization and denitrification technology, comprising a storage tank, the left side of the storage tank is fixedly connected with a feed pipe, and the right side of the storage tank is fixedly connected with an outlet A feed pipe, the right side of the discharge pipe is fixedly connected with a desulfurization reaction tank, the top of the desulfurization reaction tank is fixedly connected with a first connecting pipe for discharging purified flue gas, and the bottom of the first connecting pipe is fixedly connected with a heat conduction pipe; By setting up the lifting plate, the lifting plate moves up and down in the storage tank continuously with the rotation of the transmission shaft, thereby stirring the lime water in the storage tank, so that the heat in the exhaust gas is converted into the lime water, reducing on the one hand Lime water needs to provide additional heat in order to reach a certain reaction temperature. On the other hand, the exhausted gas heat is recycled, thereby reducing the waste of heat sources.
Description
technical field [0001] The invention relates to the technical field of desulfurization and denitrification, in particular to a waste heat utilization device for desulfurization and denitrification of sintering flue gas. Background technique [0002] The nitrogen oxides and sulfur oxides in the flue gas produced by sintering are one of the main sources of air pollution. The flue gas needs to be mixed with ammonia gas for denitration treatment, and then mixed with lime water for desulfurization treatment. After desulfurization and denitrification treatment, the The flue gas can be discharged into the atmosphere. [0003] In the invention case of a sintering flue gas desulfurization and denitrification waste heat utilization device disclosed in the prior art, the Chinese patent application number of the invention patent is CN201710369398.X, a denitrification system and method that directly utilizes the heat of sintering ore, the system includes a sintering machine , cooling eq...
