Problems solved by technology

[0002] At present, in the actual production process, most of the slurry circulation pumps equipped with each wet desulfurization tower are multiple power frequency pumps, and the operators are based on the inlet flue gas volume and inlet SO 2 The concentration is manually controlled according to experience. During the adjustment of the number of slurry circulating pumps, the slurry circulation volume is adjusted by increasing or decreasing the operation of one pump. Smooth and precise fine-tuning, there is excess or insufficient slurry circulation
Manual adjustment also has high requirements for the experience of the operating personnel, and will also increase the burden on the operating personnel

Abstract

The invention relates to an automatic slurry amount control system for slurry circulating pumps for wet flue gas desulphurization. The system is characterized in that an online data acquisition module is used for acquiring online data parameters, and a control module is used for receiving the online data parameters, automatically calculating the required slurry circulation amount, obtaining a start-stop and variable-frequency optimal configuration scheme of the plurality of power-frequency and variable-frequency combined slurry pumps according to the required slurry circulation amount, and generating a control instruction according to the obtained optimal configuration scheme; after the instruction is executed, a fine adjustment scheme of the slurry circulation amount is obtained according to the change of the SO2 concentration of flue gas at a desulfurization outlet, and a control instruction is generated according to the obtained fine adjustment scheme; and an equipment operation module is used for receiving the control instructions, changing equipment operation parameters and executing the optimal configuration scheme and the fine adjustment scheme. According to the automatic slurry amount control system for the slurry circulating pumps for wet flue gas desulphurization, the slurry circulation amount can be accurately and automatically controlled, energy is saved to the greatest extent while the SO2 concentration at the desulfurization outlet is controlled to be in a reasonable range, and the workload of operators is reduced.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to an automatic control system for slurry volume of a wet desulfurization slurry circulation pump. Background technique [0002] At present, in the actual production process, most of the slurry circulation pumps equipped with each wet desulfurization tower are multiple power frequency pumps, and the operators are based on the inlet flue gas volume and inlet SO 2 The concentration is manually controlled according to experience. During the adjustment of the number of slurry circulating pumps, the slurry circulation volume is adjusted by increasing or decreasing the operation of one pump. Slippery and precise fine-tuning, there are situations where the amount of slurry circulation is excessive or insufficient. Manual adjustment also has high requirements for the experience of the operating personnel, and will also increase the burden on the operating personnel. ...
