INDUSTRIAL PART WASHER
AR FILTRAZIONI | INDUSTRIAL PART WASHER
The filtration solution for all pollutants deriving from industrial washing processes.
It starts after the production phase of the mechanical part and any thermal-chemical treatments. To eliminate any residual substances, industrial cleaning systems wash the piece, generating aerosols and oil mists.
AR Filtrazioni has studied filtration and purification solutions for oil mists produced during washing processes.
The exhaust system for mists of oil / vapor / aerosol suitable for metal washing and surface treatment systems
Washing systems: with robot, rotary, with targeted jets, interoperational, on-board machine. Tunnels are the ecological alternative to modified solvents and alcohols for cleaning of metal surfaces and in particular of small metal parts. There are different types of washing machines but the most common are tunnel systems. Different filtering fans are installed.
TUNNEL washing plant
The tunnel system is the best known and most widespread solution in the world of industrial washing. The parts, positioned on a conveyor, travel through a tunnel passing under jets of water added with specific chemical products, until they reach the drying oven before appearing at the exit.
There two main phases generating atmospheric pollutants during the part washing.
In the first stage, the real washing, water-based solution present in the washing machine reaches a temperature of 70/90 ºC and begins to evaporate. These aerosols are contaminated by oil residues removed and volatile by definition; so that must be treated in a similar way to oil mists.
The second stage of drying process produces a vapor that must be held and filtered.
The problem of oil mists-dusts-fumes if not held in mechanical workshops.
The volatility of polluting particles such as industrial fumes, oil mists and aerosols, whether solid or liquid, entails and creates various problems for metalworking companies, operators and machine tools.
First of all, they negatively affect the health of the air and the health and hygiene conditions of the operators, in particular at the respiratory level, since the particles smaller than 0.3 microns can reach the pulmonary alveoli, compromising the respiratory tract.
Not only that, in contact with the epidermis, they create skin irritations, dermatitis and redness.
From the standpoint of production, micro-dust and oil mists pollution in the workshop considerably reduces the productivity and in particular the efficiency of the machine tools, since the stratification of pollutants invalidates the precision and tolerance of the measuring instruments, with the onerous consequence of having to increase maintenance on the most delicate components.
Dusts, oil mists and aerosols not filtered and purified, make the floor slippery, dirty the surfaces of the machine tools and the walls of the shed, on which they settle.
Without forgetting any possible fines deriving from current regulations, which impose a concentration limit for oil mists in the workplace.
Italian TLV limit 5 mg / m3
more restrictive ACGIH limit 0.5 mg / m3
