GAS WASHER FOR HORIZONTAL MOUNTING The air exhausted from the
exhauster hoods will enter the Gas
Washer, will pass through a flow rectifier located at the entrance which will
distribute it through the inside of the body where a series of special
pulverizing nozzles directed against the air flow, inject water under high
pressure, guaranteeing high atomization and coverage of the entire internal
perimeter of the body of the Gas Washer, thus capturing all the particles
which are collected in a tank where the water is re-circulated after passing
through a filter. After passing
through high efficiency droplet eliminators
the air, already free of polluting elements, and pushed by the
exhauster, can be discharged through the outlet and directly into the outside
atmosphere. The water circulation
tank should have a drain for its cleaning and a siphon system for the
polluting particles which will be conducted to a coupled grease trap, causing
the solid and floating effluents to concentrate, allowing manual cleaning
with no need to stop the Gas Washer and, consequently, the mechanical exhaust
system. The Gas Washer should
optionally have a point for a Device of automatic addition of non-foaming,
automatic, biodegradable grease detergent. It should also have an
automatic system for the programming of the cycles for heating the tank water
to dissolve the solid elements and provide the clearing of the pulverizing nozzles and internal
piping. This system should have a
programmable timer and a thermostat for control of the cycles and heating
temperature, with a view to the economy of electric energy. All the components of this system should
be armored and appropriate for the safety of the operators against shocks.
The timer and thermostat should have visible and adjustable scales to satisfy
the specific needs of each exhaust system. . The air speed inside
the body of the Gas Washer should not be higher than 3.5 m/s, guaranteeing a
maximum loss of 5% of water by drag or evaporation. All the internal components
of the Gas Washer should be metallic in compliance with the ABNT Technical
Standard 14.518 for the prevention of fires and to avoid its propagation,
which implies the total absence of any plastic materials in the exhaust air
flow inside the Gas Washer. The body and all the
internal components of the Gas Washer should be built with totally welded
galvanized steel plates with minimum gage
# 18 covered with two coats of paint for external finishing and two
coats of high grade galvanized paint for internal protection on all the
surfaces. The water circulation
pump should have outflow and pressure compatible with the pulverizing nozzles
with rotor and mechanical seal in bronze, which should be connected to the
piping by joints having brass screen suction filters easily removable for
cleaning. The Gas Washer should
have at least two manhole covers, one on each side, for internal
cleaning and perfect adaptation to
the pipes and to the assembly location.
A glass window for inspection of the pulverizing nozzles should be
provided on one of the sides. All
the electric components of the Gas Washer should be supplied so as to permit
perfect adaptation to the electric supply systems of the benefited property.
