Overview

The 304 stainless steel cyclone plate defogger is a device that uses a cyclone plate to generate rotational motion in the airflow and separates mist droplets from the gas through centrifugal force. Here is its detailed introduction: The working principle of r n is that the gas containing fog droplets enters the cyclone plate defogger and flows along the guide blades of the cyclone plate, forming a rotating airflow. Under the action of centrifugal force, the mist droplets are thrown towards the outer edge of the swirl plate, that is, the inner wall of the cylinder, and flow down along the cylinder wall under the action of gravity. Finally, they are collected and discharged, while the purified gas is discharged from the top of the defogger.

Product Details

structural composition

Swirl plateIt is usually made of a metal plate with a thickness of 1-2 millimeters. The blade angle is generally 25 °, and the central diameter is greater than 90 °. Its function is to generate rotational motion of the gas and provide centrifugal force for the separation of droplets.
Cylindrical coverWelded on the swirl plate with a certain gap between it and the tower wall, it is used to collect the liquid flowing down along the wall, prevent it from being carried by the rotating gas for the second time, and create conditions for the liquid to return to the lower tower plate.
retaining ringIt can block the mist carried by the rotating gas and prevent it from overflowing. The height and width of the blocking ring should be selected according to the tower diameter and the processed material.
cylinderGenerally made from the tower section itself, it serves as the outer shell of the demister and accommodates components such as swirl plates, providing space for the separation of gases and liquids.
return pipeReflux the remaining mist back into the tower, allowing the liquid to be recycled and improving the overall efficiency of the system.

advantage

High defogging efficiencyIt has a high separation efficiency for large particle size mechanical mist and cohesive mist, generally reaching 85% to 95%The defogging efficiency of some high-efficiency cyclone plate defoggers can even reach around 90% -99%.
High operational flexibilityWhen the airflow passes through the cyclone plate defogger, the pressure drop is relatively low, usually between 200-500Pa, which enables the equipment to maintain good defogging effect in a large range of airflow velocities, is not easily blocked, and has strong adaptability to changes in gas flow rate.
simple structureThe structure of the equipment is relatively simple, without complex transmission devices and vulnerable parts, easy to install, and requires minimal maintenance, reducing the maintenance cost of the equipment.
Long service lifeIf high-quality materials such as corrosion-resistant stainless steel or plastic are used to manufacture the cyclone plate defogger, under reasonable working conditions, its service life can reach 3-5 years or more.
AdaptableCapable of adapting to various working conditions and meeting different gas-liquid separation requirements, it can function normally in harsh environments such as room temperature, high temperature, and high humidity. It has good adaptability to different droplet sizes, gas flow rates, and liquid properties.

shortcoming

High installation requirementsThe installation of the cyclone plate defogger requires professional personnel to operate, and professional tools must be used for installation and positioning. The installation accuracy requirements are high, otherwise it may affect the normal operation and defogging effect of the equipment.
Sensitive to airflow distributionUneven airflow distribution can affect the performance of the defogger. If the gas is not well distributed before entering the defogger, it may lead to a decrease in defogging efficiency in local areas, and even secondary entrainment of fog droplets.
There is a risk of scalingUnder certain specific operating conditions, such as when dealing with gases containing high concentrations of suspended solids or easily scaling substances, the surface of the cyclone plate defogger may experience scaling, which can affect the flow of air and the defogging effect. Regular cleaning and maintenance are required.

Application field

chemical industryIn the production processes of synthetic ammonia, fertilizers, pharmaceuticals, etc., it is used to separate liquid droplets and solid particles in gases, improve product quality, reduce material loss, and also help prevent equipment corrosion and blockage, ensuring smooth production.
petroleum industryIt can be used for gas-liquid separation in processes such as oil and gas separation and petroleum refining, removing mist droplets and impurities from gases, improving oil and gas processing efficiency and quality, and ensuring the safe and stable operation of petrochemical plants.
Metallurgical industryIn metallurgical production such as steel and non-ferrous metals, purification treatment of flue gas is carried out to remove fog droplets and dust, reduce pollutant emissions, protect the environment, and also recover valuable metal resources.
environmental protection industryWidely used in environmental engineering such as exhaust gas treatment, desulfurization and denitrification, as one of the key equipment for exhaust gas treatment, it can effectively remove fog droplets from exhaust gas, reduce the emission concentration of pollutants, and meet the requirements of environmental standards.
