A semi-dry reaction tower control system

Abstract

The invention provides a semi-dry reaction tower control system, the system comprising: a semi-dry reaction tower; a weighing module, the weighing module is used for real-time monitoring of the weight of the semi-dry reaction tower to obtain The weight data of the semi-dry reaction tower; the anti-blocking module, the anti-blocking module is used to perform an anti-blocking operation on the semi-dry reaction tower to remove at least part of the ash accumulation in the semi-dry reaction tower; and A control module, the control module controls the anti-blocking module, and the control includes a quality control mode. In the quality control mode, the control module controls the anti-blocking module according to the weight data of the semi-dry reaction tower. The anti-blocking module is controlled so that the anti-blocking module performs the anti-blocking operation. According to the control system of the semi-dry reaction tower of the present invention, excessive ash accumulation inside the semi-dry reaction tower is avoided, energy waste and safety risks are reduced.

Description

technical field [0001] The invention relates to the field of waste incineration flue gas treatment, in particular to a semi-dry reaction tower control system. Background technique [0002] With the improvement of domestic living standards, the amount of waste produced per capita is gradually increasing. As the most effective means of waste disposal, waste incineration has attracted widespread attention. In the waste incineration treatment, the purification treatment of the flue gas emitted by incineration is the focus of people's attention. [0003] Flue gas from waste incineration contains a large amount of SO 2 , HCl and HF and other acid gas pollutants, in order to remove these acid gases, the flue gas is usually passed into a semi-dry reaction tower to make the absorbent react with the acid gas in the flue gas to form dry substances. After a period of reaction, these dry substances and absorbents often cause dust accumulation inside the semi-dry reaction tower, which n...

AI Technical Summary

Problems solved by technology

On the one hand, the degree of ash accumulation in the reaction tower judged by the operator based on experience largely depends on the subjective judgment of the operator, and the reliability is poor; Real-time chain control, poor adaptability

When the working conditions fluctuate greatly or the operation is improper, the safety, reliability and economy of the operation of the reaction tower cannot be guaranteed; when the ash accumulation inside the reaction tower is too heavy, the load of the ash hopper increases, the pressure loss of the equipment and the energy consumption of the operation increase; When a large area of ​​ash accumulates in the reaction tower and collapses instantly, it is often blocked at the outlet of the reaction tower, resulting in increased pressure loss and increased operating costs. Bucket fall and other safety accidents
