Mist is formed in chemical and
manufacturing industries by three different methods. In mechanical methods, physical shearing type forces may break up or atomize a
liquid to form an aerosol mist. Mists created by mechanical methods are larger
in size i.e. more than 1 micron in size. In cooling methods, when a gas stream
is saturated with vapor and is exposed to a temperature drop, the cooled vapor
in the gas stream will be condensed to form a mist. The particles which are
formed in cooling methods are usually less than 1 micron in size. In the
process of reactions, the chemical reactions between two or more gases in
specific temperature and under specific pressure, creates mist. This type of
mist consists of very tiny particles which are difficult to capture.
Formation of
mist in the industries has many adverse effects. First and most of all the mist
formed due to hazardous chemicals and oils cause serious health problems.
Continuous formation of mist lowers the life of the machines, equipments and
cutting tools, thus increase in maintenance and repairs costs. Also working in
such atmosphere lowers morals of the employees. This reduces overall
productivity of the industry. To get rid of these problems, one of the renowned
pollution control companies, ‘Powertech Pollution Controls’ has come up with a
unique device called as mist collector or mist extractor. This device is
recognized by the name ‘Fume Killer’ in the market.
A mist collector or a mist extractor is a device which is used to remove the mist thus
helping effectively in pollution control. Different types of mechanisms are
used in different types of mist collectors according to their designated use.
The ‘Fume Killer’ of ‘Powertech Pollution Controls’ is well equipped to filter
and control the fumes produced by oils and coolants. These mist
collectors or mist extractors are used to remove mist from the mist generating
sources like,
·
CNC and Non CNC machines.
·
Electro-discharge machines.
·
Induction hardening.
·
Spark erosion machines.
