Introduction to common standard wire mesh demister types
Types of wire mesh demisters: stainless steel wire mesh demister, stainless steel wire mesh demister, stainless steel demister, stainless steel demister, stainless steel mist collector.
Wire Mesh Defoamer Type:
⒈ HG5-1404-81, HG5-1405-81, HG5-1406-81
Standard ascending air pipe type (1404), reduced diameter type (1405) and full diameter type (1406). A variety of standard drawing numbers are pre-designed, and customers can contact us for them. For example, the standard drawing number is marked HG5-1406-81-60, 316L/Q235A, which means that the wire mesh is made of 316L stainless steel, the grille is made of Q235A, and the full diameter type is top-mounted, with a diameter of 1800mm and a height of 150mm.
In addition to the standard drawing numbers, the height of the demister can be divided into 50mm, 80mm, 200mm, 250mm, 300mm, etc. The shape and diameter can also be designed and produced according to the actual needs of customers.
⒉ HG/T21618-1998
The new standard combines the three installation forms of riser type, reduced diameter type and full diameter type; proposes four mesh types of SP, HP, DP and HR and expands the types of material selection; and increases the spacing density in setting specifications and sizes.
Marking example: HG/T21618 Wire Mesh Demister S1600-100 SP 304/304, which means that the grille and wire mesh are both made of 304 stainless steel, top-mounted, with a diameter of 1600mm and a height of 100mm, and the mesh type is SP wire mesh demister.
3. Drawer type wire mesh demister (HG/T21586)
Drawer type wire mesh demister is suitable for occasions where demister components need to be cleaned or replaced frequently, such as drying towers and absorption towers in sulfuric acid plants. The nominal diameter range is DN300mm～DN5000mm, with a total of 56 types. When ordering, only the drawing number and the selected material are required (316L, NS-80 and RS-2 are commonly used wire mesh materials in sulfuric acid plants).
Marking example: HG/T21586.11-98 WME-1000-100 316L/Q235-A, which means a drawer-type wire mesh demister with a diameter of 1000mm and a height of 100mm, the wire mesh is made of 316L, the grille is made of Q235-A.
4. Peak-shaped (flow-guiding) wire mesh demister
Peak wire mesh demister has the following features:
• The actual defoaming area of the mesh block is increased by more than 15%, which makes it easier to adjust the air speed and resistance during design and significantly increases the defoaming effect.
• One layer of peak-shaped wire mesh demister can achieve the defoaming effect of two layers of wire mesh demisters, saving installation space and reducing the cost of the entire device.
Conventional models of wire mesh demisters: Conventional models of stainless steel wire mesh demisters are: top-loading and bottom-loading.
