Desulfurization tower metal baffle-type demister, boiler room mist separator (demister/mist eliminator) is mainly composed of fixed devices such as wavy blades, plates, and clips. During the operation of the wet flue gas desulfurization process, the absorption tower is prone to produce "mist" with particle sizes of 10-60 micrometers. This mist not only contains moisture but also dissolves lactic acid, lactic acid salt, sulfur dioxide, etc. It also causes contamination and severe corrosion of the fan, heat exchanger, and flue. Therefore, in the wet flue gas desulfurization process, it is required to remove mist from the absorption equipment. The purified gas must be demisted before leaving the absorption tower. The demister nozzle is one of the main components of the demisting system, and it is mainly made of high-wear-resistant plastic, offering a long service life.

Introduction

Desulfurization tower metal baffle-type demister and evaporator mist separator are important components. The function of the demister is to capture the mist particles and slurry droplets carried by flue gas during the spray absorption process. The efficiency of the demister is not only related to its structure but also to the specific gravity and particle size of the mist particles, as well as the atomization particle size of the nozzle, the viscosity of the absorbent liquid, the spray claw force, and the nozzle structure. Properly matching the demister performance with the mist particle diameter is essential for achieving good demisting results.

If defogging is inadequate, the smoke will carry slurry downstream to equipment such as the gas heater, induced draft fan (commonly used in industrial boiler desulfurization), and flue, leading to blockages, severe vibration of the induced draft fan, severe corrosion and scaling of the flue, and ultimately forcing shutdown.

Structure

Desulfurization tower metal baffle type demister, the evaporator mist separator is mainly composed of plates and support devices. The plates are generally made of two major materials: high polymer materials (such as polypropylene PP, FRP, etc.) or stainless steel (such as 316L, 317L, etc.). They are usually divided into streamlined and zigzag types.
