Activated carbon flue gas purification system and roller feeder discharge flow measurement method thereof

Abstract

The invention discloses an activated carbon flue gas purification system and a roller feeder discharge flow measurement method thereof. The method comprises the following steps: measuring the quantityof activated carbon in a buffer bin of an adsorption unit in real time through a sensor arranged at the buffer bin; obtaining the initial material quantity L1 of the buffer bin at the initial measurement time t1 and the final material quantity L2 of the buffer bin corresponding to the final measurement time t2 through controlling the starting and closing states of the to-be-measured roller type feeder, and directly calculating the discharge flow of the corresponding to-be-measured roller feeder according to the preset measurement interval time T2, thereby achieving online accurate measurement. Therefore, the method provided by the embodiment of the invention makes the most of the structural characteristics of the adsorption unit of the activated carbon flue gas purification system, and achieves the combination of material flow control and material weight detection through the sensor for weighing arranged at the buffer bin and further achieves the online accurate measurement of the discharge flow 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...
