Abstract

The invention discloses an activated carbon desulfurization adsorption tower temperature control method and device. The temperature values of all temperature monitoring points in the an adsorption tower are obtained in real time, the primary heating rate of each temperature monitoring point is calculated according to the obtained temperature values, and when the primary heating rate of at least one temperature monitoring point meets a preset early warning condition, the risk level of the adsorption tower is judged once according to a preset corresponding relationship between the rate and the level, and finally control operation corresponding to the hit risk level is executed so as to control the temperature of the adsorption tower. According to the method, the over-temperature early warning of the adsorption tower is realized according to the heating rate, and the risk level of the temperature of the adsorption tower is judged according to the heating rate so as to execute the control operation corresponding to the hit risk level instead of directly performing early warning and judgment according to the temperature value, so that the early warning time can be advanced, the phenomenon that the local temperature of an activated carbon bed layer is sharply increased within a short time is avoided, and the reliability of activated carbon bed layer temperature control is improved.

Description

technical field [0001] The present application relates to the technical field of sintering flue gas purification, in particular to a method and device for controlling the temperature of an activated carbon desulfurization adsorption tower. Background technique [0002] Iron and steel enterprises usually use activated carbon flue gas purification technology to remove SO from sintering flue gas 2 , NOx, dust, dioxins, heavy metals and other harmful components, so as to realize the clean emission of waste gas from the sintering plant of the enterprise. [0003] figure 1 A kind of activated carbon flue gas purification system is shown, the system includes adsorption tower 1, desorption tower 2, acid system 3, buffer bin 4 for adsorption tower 1 conveying activated carbon and feed device 5 at the bottom thereof, and buffer bin 4 Forward conveyor 61 for conveying activated carbon. When the system is running, the forward conveyor 61 transports the activated carbon particles to t...
