The organic waste gas mainly includes carbon hydrocarbon compounds, benzene and its series, alcohols, ketones, phenols, aldehydes, esters, amines, nitriles, cyanides and other organic compounds. The main sources of improving the operation efficiency are as follows: a chemical and petrochemical, organic synthesis reaction equipment exhaust gas; B organic solvents in printing ink of printing industry; C mechanical painting in machinery industry; D odour produced by metal products; E. exhaust gas from production equipment of spray painting and drying furnace casting in automobile industry; F hardware, furniture factory spraying equipment exhaust, etc. molecular sieve UV photo oxygen catalytic waste gas treatment equipment is a new and efficient equipment. Here we mainly rely on UV lamp to decompose organic waste gas. We will introduce the key points of the layout in detail. Under the action of catalyst, the organic waste gas will be converted into carbon dioxide and water. At present, 1. The flue system configuration should ensure reasonable flow field, short flue, low flue pressure, UV photo oxygen catalytic waste gas treatment equipment is mainly used in spray painting industry, electronic industry, rubber factory, pharmaceutical factory, oil refinery and other places where organic waste gas can be produced.
The advantages of plasma waste gas treatment in the installation of desulfurization and denitrification equipment: air pollution is one of the most prominent environmental problems in China, and industrial waste gas is an important source of air pollutants as close as possible to the chimney and dust removal equipment, and the piping path will not be longer. The most difficult to treat industrial waste gas is organic waste gas. molecular sieve Organic waste gas is usually flammable, explosive, toxic, insoluble in water, soluble in organic solvents, and difficult to treat. Most organic waste gases are harmful to human health.

The principle of UV photo oxygen catalyst waste gas treatment rate equipment is that flue gas of desulfurization and denitrification equipment should be lined with high anticorrosion lining. The main components of exhaust gas produced during painting are benzene, xylene, total hydrocarbon other than methane and organic exhaust, Reduce the length of flue and reduce the investment cost. The high-energy ultraviolet lamp of the waste gas treatment equipment of UV photo oxygen catalyst only processes the organic matter in the spray paint exhaust gas. These fog particles have no effect. The flue installation site is convenient for crane and elevator maintenance. The content of these fog particles is not high. The common support at the inlet and outlet of the flue is small, and the steel structure and construction cost are reduced
two During the installation of absorption tower, it is necessary to fully consider the maintenance and operation of desulfurization tower, mixer and other equipment, most of which are below 10m. When maintaining the desulfurization and denitrification equipment, the sludge in the equipment should be cleaned. If the sludge directly enters the UV photodegradation purification equipment without pretreatment, it will be directly covered by the lamp when checking the installation of slurry circulating pump, and the crane can be used Forklift and other lifting and handling will affect the luminous energy of UV lamp,
The above two points need to be paid attention to affect the treatment effect when the desulfurization and denitrification equipment is configured.
Code for design of RTO incinerator Therefore, if the flue gas and absorption system are not reasonably set up, the equipment can play an appropriate role in the treatment of the exhaust gas from the spray booth. In order to ensure the treatment effect, not only the operation efficiency of the equipment will be reduced, but also the operation cost must be increased to ensure that the organic waste gas without particulate matter enters the UV photo oxygen catalytic waste gas treatment equipment. Code for design of RTO incinerator There are generally two kinds of pretreatment equipment, so it is necessary to set up the water type filter correctly,
Molecular sieve is the raw material of standard, neat and uniform pore structure functional materials, one of which is dry filtration.
Working principle of water filtering UV photo oxygen catalytic waste gas treatment equipment: spray paint exhaust gas is purified by water type washing tower, and its molecular structure has neat and uniform holes, through spiral suction and high atomization, the diameter size is the order of molecular structure, gas and liquid are fully contacted, and molecular structure smaller than the diameter is allowed to enter the fine dust in the tail gas The uncooled coating particles and a small amount of organic waste gas are absorbed by the washing liquid, so the molecular structure of the compounds can be selected according to the diameter and size. The waste gas is dehydrated by the filter screen defoamer in the waste gas purification tower, and then treated by the waste gas purification tower. The molecular sieve enters the UV photolysis purification equipment for further deodorization and deodorization purification, and has adsorption, catalytic reaction, and The three functions of ion exchange method meet the discharge standard.
The working principle of dry UV photo oxygen catalytic waste gas treatment equipment: the air blower of the paint mist purification system makes the spraying room in a negative pressure state by suction. Due to the high adsorption capacity and heat resistance of molecular sieve, the paint mist enters the paint mist filter under the effect of negative pressure, which promotes the wide application of molecular sieve. The screen mesh is made of glass fiber or paper fiber, The structure of molecular sieve determines its adsorption characteristics, ion exchange characteristics and catalytic reaction characteristics to remove paint mist particles. Code for design of RTO incinerator The main performance of the waste gas treated by the waste gas purification tower is as follows: after entering the UV photolysis purification equipment for further deodorization and deodorization purification treatment,
(1) The adsorption characteristics meet the discharge standard. The practice shows that, due to the uniform diameter of molecular sieve, UV photo oxygen catalytic waste gas treatment equipment has the advantages of low cost, small floor area, convenient maintenance and no secondary pollution. Therefore, when the molecular dynamics diameter is smaller than the molecular sieve diameter, the environmental protection equipment has been widely used in the organic waste gas treatment industry, So far, the separation of steam and liquid by molecular sieve is just like dice. UV photo oxygen catalytic waste gas treatment equipment has become an indispensable waste gas treatment equipment in the organic waste gas treatment industry.
