UV Photocatalytic Deodorization Equipment
UV photocatalytic equipment is an efficient waste gas treatment
device, which is widely used in the field of industrial waste gas
treatment through the combination of UV photolysis technology and
catalytic oxidation technology to decompose the harmful substances
in the waste gas. It is especially suitable for removing odour,
volatile organic compounds (VOCs) and some toxic and harmful gases,
such as benzene, toluene, xylene, hydrogen sulphide, ammonia and so
on.
1. Working principle
The working principle of UV photocatalytic equipment mainly
includes the following stages:
(1) UV photolysis
The high-energy ultraviolet lamps inside the equipment emit
ultraviolet light with wavelengths of 185nm and 254nm, which
directly destroys the chemical bonds in the molecules of the
exhaust gas and breaks down the large-molecule pollutants into
small-molecule compounds. For example, the benzene ring is
decomposed into CO₂ and H₂O.
(2) Ozone oxidation
UV light can also break down oxygen molecules (O₂) in the air to
form highly reactive ozone (O₃). Ozone is a strong oxidising agent
that can further oxidise harmful substances in exhaust gases and
convert them into non-toxic and harmless substances.
(3) Catalytic oxidation
The interior of the equipment is usually equipped with a catalyst
coating or filler (e.g., titanium dioxide TiO₂), which, through the
excitation of ultraviolet rays, forms highly active free radicals,
further accelerating the degradation of hazardous substances in the
exhaust gas.
(4) Discharge to standard
After the above treatment, the exhaust gas is converted into
harmless substances such as carbon dioxide and water, and meets the
environmental emission standards.
2. Equipment structure
UV photocatalytic equipment usually consists of the following
parts:
UV lamp: the core part of the equipment, generating high-energy UV
light for decomposition and oxidation of pollutants.
Equipment shell: usually made of stainless steel or carbon steel,
corrosion-resistant, anti-light leakage.
Catalytic reaction chamber: the interior is coated with catalyst or
filled with catalyst material to enhance the oxidation reaction of
the exhaust gas.
Control system: including fan, electric control device, lamp
control switch, etc., used to regulate the operating parameters of
the equipment.
Air inlet and outlet: reasonably designed airflow channels to
ensure that the exhaust gas stays in the equipment long enough to
increase the treatment efficiency.
