Compact Spiral Tube Mist Collector for Mist Smoke and Vapor Removal

Compact Spiral Tube Mist Collector for Mist Smoke and Vapor Removal

The high-efficiency double-spiral-tube-bundle dust and mist eliminator relies on high-speed centrifugal force to spread and separate the liquid droplets in the flue gas to the spiral rifling gravity and fall to the slurry pool. The design flow rate is between 4.0" and 8.0m/s. The flow rate range is wide and the limitations are small. The higher the flow rate, the dust and mist are removed. The better the effect, you don't have to worry about secondary entrainment of droplet dust due to too high flow rate, and the principle of centrifugal force is used to remove dust with high efficiency, which can achieve discharge droplets <30mg/m and dust <5mg.


 

STRUCTURE:

The high-efficiency double-spiral-tube-bundle dust and mist eliminator is composed of 3 structures: outer cylinder, spiral rifling and spiral auger.

The inner wall of outer cylinder is smooth, the cylinder is vertical, the cross-section is smooth, and there is no eccentricity.

The spiral rifling is a centrifugal counter-rotation design, which ensures that the separated dust and mist droplets fall into the slurry pool along the rifling, preventing secondary entrainment from the collision between high-flow flue gas and falling dust droplets.

Characteristics of the usage environment:
The use environment of the high-efficiency double-spiral-tube-bundle dust and mist eliminator is ~80C saturated clean flue gas containing a large number of liquid droplets and dust. It is characterized by a large amount of mist droplets and a range of mist droplet size distribution. The factory consists of liquid droplets, condensation droplets and Composition of dust particles: Dust removal and defogging mainly remove liquid droplets and dust particles. The transformation period is short and maintenance is convenient. The spiral rifling and spiral auger can be dismantled for maintenance and cleaning at will. There is no need to modify the original demister support beam structure and can be installed directly.

The agglomeration of small droplets and particles:
A large number of small droplets and dust particles are condensed and gathered in the flue gas under the conditions of high-speed movement of the spiral auger airflow. The droplets and dust in the flue gas achieve gravity dispersion and collision, and the droplets and dust are separated into the running water tank, where they condense and gather into large particles, thereby achieving separation from the gas phase.

Capture of large droplets and liquid films:
The mist droplets and dust are separated into the spiral rifling running water tank. The liquid film will capture the small droplets that come into contact with its surface. The spiral rifling is designed to counter-rotate. The high-speed airflow cannot contact the mist droplets and cause mutual collision. Secondary entrainment occurs, and the mist and dust in the water tank fall smoothly into the liquid pool.

Features:

The dust removal and mist removal efficiency is high, reaching less than 5mg/m; it completely eliminates gypsum rain and has low operating costs.

It does not increase additional operating costs and only needs to use the original absorption tower space for renovation without changing the external structure of the absorption tower;

The renovation and installation period is short, and the renovation can be completed within a week. The investment cost is low, the operating cost is saved, and the economy is good.

It is easy to install and maintain, and all parts of the equipment can be disassembled, repaired and cleaned.

Breaking through the limitations of the traditional complex installation and maintenance structures of flat panels, roof ridges, pipe bundles, and dust collectors and defoggers.
