Introduction

The plant in subject is realized for an Italian foundry specialising in the production of aluminium alloys and treats the flue gas from a reverbetory aluminium scrap melting furnace.

 

Problem

 

The old filtration system was obsolete and had problems of clogging and deterioration due to condensate formation.

The main difficulty was a very limited space for installation and manoeuvring with a very short production downtime for dismantling the old system and assembling the new one.

 

Solution

 

TVT has designed and realised a gas treatment plant consisting of a axial cyclone, a basic reagent storage, dosing and injection system, and a bag filter with compartmentalisation to ensure access for maintenance during operation.

​

The plant is designed to treat the flow rate of 110,000 m3/h at a working temperature of 155 °C. The filter body is made of CORTEN-A steel and complete of thermal insulation with mineral wool to prevent any condensation formation.

​

The entire plant is designed for fully automatic use and equipped with an electrical control panel complete with a man-machine interface panel.
