Demister a rete metallica a cassetto
The retractable demister is an innovative gas-liquid separation device that combines wire mesh demister drawer with convenient maintenance. It assembles multi-layer high-efficiency wire mesh demister pads in a retractable metal frame, which is convenient for online inspection, cleaning or replacement, greatly improving operation reliability and maintenance efficiency. The retractable demister design is widely used in towers and piping systems that require frequent maintenance or compact space.

Caratteristiche e vantaggi del prodotto
Drawer-style design
The wire mesh demister pad is loaded on a slide-out frame, similar to a drawer demister pad. There is no need to remove the entire tower cover, making maintenance faster and safer.
Efficient droplet capture
The multi-layer wire mesh structure provides abundant collision and coalescence channels, easily intercepting 3-5μm droplets to ensure clean gas downstream of the tower.
Bassa caduta di pressione e flusso elevato
Optimize the wire mesh stacking angle and porosity to achieve minimum resistance in the wire mesh demister drawer mode and reduce system energy consumption.
High temperature and corrosion resistance
316L stainless steel and other composite materials can meet the requirements of -40 to 350℃, strong acid and strong alkali gas environments, and have a long service life.
Modular customization
Supports a variety of thicknesses, frame materials and sizes, and is compatible with various tower types and pipelines. LiandaFiltration can provide one-to-one selection services.
Industria di applicazione del prodotto
Petrochemical distillation tower: interception of droplets and protection of reflux liquid at the top of the tower and the upper part of the packing layer.
Desulfurization and denitrification absorption tower: efficient retractable demister solution for SO₂ and NOₓ scrubbers.
Electronics and semiconductors: micro-mist filtration at the end of the clean gas pipeline to ensure an ultra-clean environment.
Pharmaceuticals and biological fermentation: sterile defoaming at the gas outlet of the fermentation tank to protect the back-end compressor and pipeline.
Environmental waste gas treatment: online maintenance demisting module for spray towers and scrubbers.
FAQ
Sì, il design modulare del filtro per cassetti di LiandaFiltration rende estremamente conveniente la sostituzione in loco, che di solito può essere completata in 3 minuti.
È sufficiente aprire lo sportello laterale o rimuovere la piastra di pressione per estrarre il cassetto demister in rete metallica per la pulizia o la sostituzione, senza fermare la torre o interrompere il flusso.
Se si utilizzano gas chimici convenzionali, si può scegliere l'SS304; in ambienti altamente corrosivi o con acqua di mare, si consigliano telai rivestiti in SS316L o PTFE per garantire una stabilità a lungo termine.
When the pressure drop exceeds the initial value by 30% or the separation efficiency drops below 95%, it can be withdrawn for inspection and replacement to ensure optimal operation of the system.
