Problems solved by technology

[0004] At present, the blades in the wet flue gas desulfurization demisters of power plants are all fixed-installed structures, and a single type of baffle demister is mostly used. The separation efficiency of the baffle demister is limited, especially for micron and Submicroscopic particles can hardly be captured, and many disadvantages such as poor load adaptability are also becoming more and more obvious.

Abstract

A demister according to the present invention is characterized in that it includes a demister body, and a first high-pressure flushing device, a baffle plate demister with a hook, and a second high-pressure flushing device are sequentially arranged in the demister body from bottom to top. device, hook adjustable corrugated plate defogging device and the third high-pressure flushing device, the programmable controller is respectively connected with the first control valve of the first high-pressure flushing device, the second control valve of the second high-pressure flushing device and the third high-pressure flushing device The third control valve of the device is electrically connected, and the programmable controller is electrically connected with the drive motor of the corrugated plate defogging device with adjustable hooks. It has the advantages of reasonable structure, high defogging efficiency, and strong load adaptability.

Description

technical field [0001] The invention is a mist eliminator, which is suitable for the wet flue gas desulfurization and mist removal system of thermal power plants. Background technique [0002] As of the end of 2014, the capacity of my country's thermal power desulfurization units accounted for 92.1% of the national coal power unit capacity, of which more than 90% used limestone-gypsum wet technology. In Governance SO 2 At the same time, the consumption of resources and the secondary pollution to the environment are becoming more and more serious. If the desulfurization flue gas contains a large amount of acid mist, gypsum particles and a small amount of other heavy metal particles, if they cannot be effectively removed, they will cause corrosion to downstream equipment and harm the human body. Harm, and even environmental pollution such as "gypsum rain" or "acid rain". [0003] The demister is an important equipment for gas-liquid separation in the power field. Because of ...
