Problems solved by technology

However, there are still the following problems at present: first, the conditions in the desorption tower are harsh and highly corrosive, and the airtightness of the tower must be guaranteed, and the change of gas components in the tower cannot be directly measured; second, the position of the SRG gas outlet has a high temperature (about 400 ℃), large moisture (about 30%), SO 2 High content (about 25%) and other characteristics, and contains CO 2 / CO and other gases, currently the industry does not have a gas analysis device that can continuously measure and operate in this environment

Abstract

A method for detecting the production safety of a desorption tower, comprising: 1) activated carbon that has adsorbed pollutants passes through a heating section, an SRG section, and a cooling section in a desorption tower; Exhaust, the SRG gas is sent to the water washing device through the SRG gas delivery pipeline for washing; the first gas obtained after water washing is sent to the drying device for drying through the first pipeline; the second gas obtained after drying is mixed with air and passed through the second pipeline Sent to the transformation system for transformation; the third gas obtained after transformation is sent to the dry suction system through the third pipeline for dry suction; the acid-making tail gas after dry suction treatment is discharged through the tail gas delivery pipeline; 3) Activated carbon cooled by the cooling section It is discharged from the discharge port of the analysis tower; wherein: by detecting O in the first gas 2 or CO 2 The content judges the working status of the analytical tower. by O 2 or CO 2 Content detection, early warning of the working status of the analytical tower, and guidance for the stable production of the system.

Description

technical field [0001] The invention relates to a method for detecting the working state of a desorption tower, in particular to a method and system for detecting the production safety of a desorption tower, and belongs to the technical field of flue gas treatment by activated carbon. Background technique [0002] Activated carbon flue gas purification technology has the advantages of synergistic and efficient purification of multiple pollutants, and is suitable for complex sintering flue gas components (SO 2 , NO x , dust, O 2 , water vapor, heavy metals), and large temperature fluctuations (110-180°C), it has been successfully applied to the sintering flue gas purification system. [0003] The activated carbon flue gas purification system is equipped with multiple subsystems such as an adsorption system, an analysis system, and an acid system. Thermal desorption activation (to release pollutants) → cooling → adsorption of pollutants" recycling. The adsorption system is...
