It is mostly used for separating and collecting waterdrops from process gases and mist from smoke desulfurization systems. Hundreds of mist separators have been supplied to Japan. In the separator, a special separation element, namely, lamellar, is installed.
The dust-collection container for separated liquid (negative pressure zone), which is installed on the lamellar, gets to have negative pressure while working so the separated liquid is not inhaled into the dust-collection container or doesn’t scatter again so high separation efficiency is obtained. |
|
| 1. Principle & Structure |
This system is composed of a lamellar element, a casing, a tank for the collected liquid, and a syphone so it is possible to attach a gas inlet and outlet in the middle of the duct through a flanger. The below figure shows the cross section of the lamellar. The lamellar element is a kind of an obstructive plate and it is arranged at 45℃ against the direction of gas flow. Gases pass through the amellar while electricity flows, and the collection tank installed at the edge of the lamellar becomes to have negative pressure. On the other hand, the mist contained in gases collides with the lamellar because of the centrifugal force which is generated between inertia and gas current, and becomes attached to it. And it flows on the surface of the lamella and is inhaled into the collection container. The liquid collected in the container flows down to the tank for the collected liquid due to gravity, which goes through syphone and is continuously discharged out.
The collection container of the lamellar becomes to have negative pressure so there is no re-scattering of the separated liquid. And lamellar is installed according to the characteristics of gases and mist so the separation efficiency is very high. |
|
| 2. Features |
1. High separation
efficiency |
It becomes different, depending on the particle diameter of mist, content, specific gravity, and viscosity, but separation efficiency is over 99.8%. |
|
| 2. No stoppage |
It is a current inertia-type mist separator so it is not blocked even by dust-containing gases.
In addition, for the mist containing very viscous dust, a cleaning system can be installed. |
|
| 3. Low pressure drop |
Lamellar element has small resistance so even though gas velocity is high, pressure drop can be treated low. |
|
| 4. High gas velocity |
Normal velocity is 5~7m/sec. |
|
5. Small installation
area |
Velocity is maintained high so the filtering area of lamellar elements is small against velocity so lamellar separator takes a small area. |
|
6. Low installation cost
for large gas quantity |
Velocity is high so the system is very compact and the installation cost is low. |
|
| 7. Easy repair |
Like a wire mesh or a ceramic filter, there are no stoppage and driving part so it is easy to repair. No manipulation is necessary during operation. |
|
8. Heat and corrosion-
resistant |
Element can be made of any of stainless steel and plastics, and it is possible to select a material suitable for the gas conditions. |

| Remark |
Lamellar Mist Separator is customized to meet your requirements using the above elements. |
|
|
| 4. Applications |
This system is used for separating the below materials.
Sulfuric acid, Nitric acid, Hydrochloric acid, Maleic anhydride |
|
| 5. Place of Use |
This system is used for the separation of such materials as sulfuric acid, nitric acid, hydrochloric acid, maleic anhydride acid, maleic phthalate acid, magnetic soda, tar mist, synthetic detergent, fatty acid, mist in high pressure gas, and other bubbles. It is also used for condensation, cleaning, absorption, and reaction. However, through the pre-treatment in a cleaning liquid, this system can separate dust, slurry, and a gas absorbing liquid. |
