Embodiment Construction

[0082] The measurement method provided in the embodiment of the present application is based on the structural characteristics of the activated carbon flue gas purification system. When the roller feeder is unloading, the amount of material discharged from the roller feeder is equal to the amount of material that the activated carbon in the buffer bin flows into the corresponding small chamber. Furthermore, each small chamber can be filled with activated carbon to give full play to the adsorption of activated carbon. Therefore, the reduced amount of material in the buffer bin can be used as the amount of material discharged by the roller feeder. According to this equivalence relationship, the technical solution of the present application controls the opening and closing of the roll feeder to be measured to obtain the change of the amount of activated carbon in the buffer bin under different conditions, thereby obtaining the discharge flow rate of the roll feeder. The technical ...

Abstract

The application discloses an activated carbon flue gas purification system and a method for measuring the discharge flow rate of the roller feeder. The sensor installed at the buffer bin of the adsorption unit can measure the amount of activated carbon in the buffer bin in real time; Measure the opening and closing status of the roller feeder, and obtain the initial measurement time t 1 The initial material volume of the buffer bin L 1 , and the measurement termination time t 2 The corresponding end material volume L of the buffer bin 2 , and then according to the preset measurement interval time T 2 , directly calculate the discharge flow rate of the corresponding roller feeder to be measured, and realize accurate online measurement. It can be seen that the measurement method provided in this embodiment makes full use of the structural characteristics of the adsorption unit of the activated carbon flue gas purification system, and by setting a sensor for weighing at the buffer bin, the combination of material flow control and material weight detection is realized, and further Realize online and accurate measurement of the discharge flow rate of the roller feeder.

Description

technical field [0001] The present application relates to the technical field of flue gas purification, in particular to an activated carbon flue gas purification system and a method for measuring the discharge flow rate of a roller feeder. Background technique [0002] The iron and steel industry is a pillar enterprise of the entire national economy. However, while it makes an important contribution to economic development, it is also accompanied by serious air pollution problems. For example, the sintering flue gas produced in the sintering process includes pollutants such as sulfur dioxide, nitrogen oxides, and dioxins. After the sintering flue gas is discharged into the atmosphere, it not only pollutes the atmosphere, but also poses a threat to human health. For this reason, the iron and steel industry usually adopts activated carbon flue gas purification technology, that is, materials with adsorption function (such as activated carbon) are placed in the flue gas purific...
