Problems solved by technology

In the actual operation process, due to the fluctuating flue gas volume caused by boiler load fluctuations and the fixed angle of the swirl vane of the emulsifier, the emulsified layer cannot be guaranteed to be completely formed, which makes the desulfurization effect not stable enough.
In the existing technology, this problem is alleviated to a certain extent by setting two layers of emulsifier swirl vanes with different angles, but it cannot respond quickly to the rapid change of the flue gas volume caused by the fluctuation of the boiler load, and the control of the desulfurization reaction also belongs to the only Coarse control to ensure sufficient gas-liquid mass transfer, generally speaking, cannot fully guarantee the effect of flue gas desulfurization

Abstract

A quantitative emulsification and desulfurization process for flue gases configured to perform quantitative emulsification and desulfurization on flue gases by means of an emulsification and desulfurization system. The emulsification and desulfurization system comprises a circulation pipeline for flue gas circulation, and an agent delivery pipeline and agent addition pipeline provided on an emulsifier. A desulfurization pump is provided on the agent delivery pipeline. The agent addition pipeline is in communication with the agent delivery pipeline, and the joint location is provided between a first valve and a second flow meter. The desulfurization pump is provided with a second valve, and provided with a variable-frequency drive controlling operation thereof.

Description

Technical field [0001] The invention relates to a desulfurization treatment process for industrial boiler flue gas, in particular to a quantitative emulsification desulfurization process for flue gas. Background technique [0002] Pneumatic emulsification desulfurization tower is currently one of the most advanced equipment used in industrial boiler desulfurization. Its core component is a pneumatic emulsifier. The desulfurization effect depends on the formation of the emulsification layer in the emulsifier. In the actual operation process, due to the unstable flue gas volume caused by the fluctuation of the boiler load and the fixed angle of the swirl vane of the emulsifier, the emulsified layer cannot be completely formed, which makes the desulfurization effect not stable enough. In the prior art, this problem is alleviated to a certain extent by arranging two layers of emulsifier cyclones with different angles. However, it cannot respond quickly to the rapid changes in flue ga...
