Treatment device and method for flue gas component absorption tube

Abstract

The invention discloses a treatment device and method for a flue gas component absorption tube. The treatment device for the flue gas component absorption tube comprises a sliding table module, an electrode bracket, a copper bar electrode, a flue gas component absorption tube, a tube fitting bracket, an electrolyte storage tank, a peristaltic pump, a funnel, a PLC (Programmable Logic Controller) and an adjustable direct-current power supply, wherein a bottom outlet of the funnel is inserted into the flue gas component absorption tube; one end of the electrode bracket is horizontally fixed onto a sliding block in the sliding table module; the upper end of the copper bar electrode is fixed onto the other end of the electrode bracket; the lower end of the copper bar electrode penetrates through the funnel and is inserted into the flue gas component absorption tube; a negative electrode of the adjustable direct-current power supply is connected with the upper end of the copper bar electrode; a positive electrode of the adjustable direct-current power supply is connected with the outer wall of the flue gas component absorption tube; an inlet of the peristaltic pump is communicated with the electrolyte storage tank; and an outlet of the peristaltic pump is communicated with an inlet in the side face of the funnel. The device and the method can be used for treating the inner wall of the flue gas component absorption tube.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a treatment device and method for a flue gas component absorption pipe. Background technique [0002] Flue gas online monitoring system (CEMS) refers to a device that continuously monitors the concentration and total emission of gaseous pollutants and particulate matter emitted by air pollution sources and transmits the information to the competent department in real time. It has been widely used in coal-fired power plants, iron and steel smelting, etc. in recent years. Pollutant monitoring of industrial flue gas emissions. [0003] The flue gas component absorption tube is one of the key components in the sampling part of a type of flue gas on-line monitoring system. When the flue gas online monitoring system performs flue gas sampling, the inner surface of the flue gas component absorption tube forms a continuous water film under the condition of continuous exte...

AI Technical Summary

Problems solved by technology

When the flue gas online monitoring system performs flue gas sampling, the inner surface of the flue gas component absorption tube forms a continuous water film under the condition of continuous external water replenishment. When the flue gas passes through the flue gas component absorption tube, the sulfur dioxide, ammonia, etc. The water-soluble components dissolve into the water film, and the subsequent instrument analyzes the discharged aqueous solution to obtain the concentration of pollutants in the flue gas. In order to ensure the best absorption effect of the flue gas component absorption tube, it is necessary to The inner surface of the gas component absorption tube is treated to make the surface sufficiently hydrophilic to form a complete and continuous liquid film, but the prior art does not provide specific treatment devices and methods
