φ4000 mm plus stainless steel corrugated plate mist eliminator

1. stainless steel corrugated plate mist eliminator application

2. Factors affecting the performance of stainless steel corrugated plate mist eliminator:

• flue gas flow rate:
  • the flue gas flow rate is expressed in terms of the air bed gas velocity u, and sometimes by the kinetic energy factor F of the air bed gas, which is an important technical parameter. Its value will directly affect the demisting efficiency and pressure drop of the equipment, and it is also an important basis for equipment design or production capacity accounting.
• demisting efficiency:
  • demisting efficiency refers to the ratio of the mass of droplets captured by the mist eliminator in unit time to the mass of droplets entering the demister.
• system pressure drop:
  • ​system pressure drop refers to the pressure loss caused by flue gas passing through the vane pack mist eliminator. The larger the system pressure drop is, the higher the energy consumption will be.
• pitch of vane plates:
  • the selection of the distance between vane plates is very important to ensure the efficiency of de-misting and maintain the stable operation of the mist eliminating system.
• mist eliminator stages:
  • in the process of mist eliminating, in order to increase the efficiency of mist eliminator, folding plates are usually connected to form a multi-stage mist eliminator. Generally, the more the stages are, the higher the efficiency of mist eliminator is. However, the resistance of the system will be greatly increased while the efficiency is improved, which not only increases the energy consumption of the system, but also threatens the normal operation of the system. Therefore, the number of vane plates should not be too many, generally two to three levels are appropriate.
• flushing interval of vane pack mist eliminator.

3. corrugated plate mist eliminator, more reference info,

In order to ensure the smooth field installation, the pre assembly of the demister parts should be carried out before leaving the factory to ensure assembly size.

The size requirement of droplets removed by demister is as follows:

The limit size of the droplet is a function of the load of the absorber. At 100% load, the size of the removed droplet after two-stage plate is 50 μm.

Under all operating conditions (up to 110% load), the free residual moisture downstream of the demister should not exceed 20mg / Nm3.

Technical specifications and performance requirements

The demister is installed at the outlet of the clean flue gas to separate the entrained droplets. The plate demister is made of corrugated plate, and the blade thickness is as per order.

The design, installation and operation of the demister shall ensure high availability and good demisting effect. It must also have very high removal efficiency for very small water droplets.
