Automatically controlled desulphurizing agent slurry formulating device

Abstract

The invention discloses an automatic control device for preparing desulphurizing agent seriflux, comprising a desulphurizing agent quantitative feeding device, a lime slaker used for configuring a preset concentration and a desulphurizing agent seriflux tank used for storing a finished desulphurizing agent; the desulphurizing agent quantitative feeding device, the lime slaker and the desulphurizing agent seriflux tank are all connected with and controlled by a programmable controller; and according to the concentration of the desulphurizing agent seriflux, the diameter of the lime slaker and a height between two liquid indicators within the lime slaker required by the balance computation of a technological material, the single feeding amount and the feeding time of a system are calculated. The automatic control device for preparing the desulfurizing agent seriflux of the invention is capable of preparing the desulphurizing agent seriflux with a constant concentration which meets the operating requirement of the technology and is free of concentration fluctuation, and has the advantages of full-automatic running, convenient commissioning and operation and simple maintenance.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to an automatically controlled desulfurizer slurry preparation device. Background technique [0002] As the country continues to strengthen the monitoring of flue gas emissions, the desulfurization system must operate continuously and stably. The pH value of the desulfurization solution is a key process control parameter for the continuous and stable operation of the desulfurization system. However, there are many factors affecting the pH value of desulfurization liquid in the desulfurization system, and the fluctuation of desulfurization agent concentration is one of the main influencing factors. [0003] At present, the slurry preparation device of the desulfurization system generally uses a powder feeder to operate at a constant speed (adjusted by a frequency converter), and the concentration of the desulfurizer slurry is controlled by adjusting the return water ...

Problems solved by technology

At present, this control method not only needs to install an expensive mass flow meter to indirectly detect the concentration of the desulfurizer slurry, but also uses an adjustment me
