AI Technical Summary

Technical Problem

In the process of flue gas treatment with high moisture content, high sulfur content and high chloride ions, the prior art is difficult to effectively reduce the dew point of the flue gas, prevent equipment from corroding and scaling, and affect the operation and life of the electro-dust collector and bag dust collector.

Method used

Design a dust collector flue gas regulating system, including a reactor fixed at the dust collector inlet and a large-particle dust collection device, spray alkaline powder into mixing with the flue gas through multiple powder spray devices, and use rotating elements to increase contact time and uniformity, and automatically adjust the amount of powder spray through SO2 detection sensor and temperature, humidity and pressure sensors to form large particles of dust for pre-dust removal and reuse.

Benefits of technology

Effectively reduce the dew point of the flue gas, prevent equipment corrosion and scaling, improve dust removal efficiency, extend the service life of the equipment, reduce resource waste, and realize automated control.

Abstract

The invention discloses a deduster flue gas conditioning system and method.The system comprises a reactor fixedly connected to an inlet flue pipeline of a deduster, a plurality of powder spraying devices are arranged on the front portion of the reactor, an outlet of the reactor is connected with a large-particle dust collecting device, the upper portion of the collecting device is connected with an inlet of the deduster, and the lower portion of the collecting device is connected with an outlet of the deduster. Large-particle dust is conveyed into the alkaline material bin through the conveying device or conveyed into the desulfurizing agent preparation device; an outlet of the alkaline material bin is connected with the powder spraying device, and the SO2 detection sensor, the temperature sensor, the humidity sensor, the pressure sensor and the computer control system can receive data of all the sensors in real time and regulate and control the powder spraying amount of the powder spraying device and the working state of the reactor according to the data situation. The invention effectively solves the problems of influence on the operation of an electric dust collector, paste blockage of a bag-type dust collector, corrosion of equipment by acid dew and the like in the treatment process of flue gas with high water content, high sulfur content and high chloride ion content.
