Enameled wire workshop exhaust gas is mainly composed of benzene, toluene, xylene, non-methane hydrocarbons, organic solvents, etc., mainly in the spraying and drying process, which is characterised by colourless, very irritating, at this stage for the enameled wire workshop exhaust treatment methods are: isolation, combustion, absorption, condensation, plasma low-temperature catalytic oxidation, adsorption and so on, the following with the Everest blue editorial to learn more about it.
Enamelled wire workshop exhaust gas treatment method target: after management, the pollutant emission reaches Guangdong Province local scale DB44/27-2001 "air pollutant emission limit value" the second period of the first level of emission scale; benzene emission concentration is lower than 12mg/m3, toluene emission concentration is lower than 40mg/m3, xylene emission concentration is lower than 70mg/m3, dust emission concentration is lower than 120mg/m3, and dust emission concentration is lower than 120mg/m3, and dust emission concentration is lower than 120mg/m3. m3.
Enamelled wire workshop exhaust gas treatment isolation method: it is through special filter material, placed in the exhaust gas discharge process, by mechanical isolation, so as to achieve the management effect.
Advantages: high efficiency of paint mist management, no technical requirements, simple manipulation.
Enamelled wire workshop exhaust gas treatment combustion method: the use of high temperature heating methods, organic waste gas will be directly burned to achieve the purpose of exhaust gas purification.
Advantages: high purification efficiency, up to 95% or more.
Enamelled wire workshop exhaust gas treatment absorption method: the use of absorbing liquid and exhaust gas mutual contact, so that the harmful substances in the exhaust gas dissolved into the absorbing liquid, so that the exhaust gas can be purified. Absorbent liquid is treated separately.
Advantages: small investment, low operating costs, simple operation.
Enamelled wire workshop exhaust gas treatment condensation method: through condensation cooling, when the temperature is lower than the cohesion point of harmful substances, gaseous harmful substances into liquid, separated from the air, so as to purify.
Advantages: no messy operation, high purification efficiency.
Enameled wire workshop exhaust treatment plasma low-temperature catalytic oxidation method: plasma is the existence of matter in addition to solid, liquid, gas state other than the fourth state, with a macro degree of electrical neutrality and high conductivity. Plasma contains a large number of active electrons, ions, excited particles and photons.
These active particles and gas molecules touch the results, resulting in a large number of strong oxidising radicals O & middot;, OH & middot;, HO2 and oxidising O3; organic molecules are subjected to high-energy electron collisions, are excited and atomic Jian breakage and the formation of small fragments of groups or atoms; O & middot;, OH & middot;, HO2, O3, etc. and the exciting O·, OH·, HO2, O3, etc. react with excited atoms, organic molecules, groups, free radicals, etc., and ultimately oxidise and degrade organic molecules into CO, CO2 and HO2.
Advantages: wide applicability, suitable for dealing with low concentration (〈1～1000ppm〉), poisonous and odorous hazardous gases, making up for the vacancies that cannot be dealt with by other technologies. As well as simple manipulation.
Enameled wire workshop exhaust gas treatment adsorption method: the use of porous activated carbon, silica bath soil, anthracite and other molecular-level large surface residual energy, organic gas molecules adsorbed to the surface, so as to purify.
Advantages: high efficiency (activated carbon adsorption up to 99% or more), widely used, simple operation, low investment costs.
Enameled wire workshop exhaust gas treatment ultraviolet deodorant method: our company introduced from abroad to improve the advanced technology, and many famous colleges and universities at home actively cooperate, the use of high-energy UV ultraviolet beams and ozone on the malodorous gases to carry out synergistic decomposition and oxidation reaction, so that the malodorous gases degraded into low molecular compounds, water and carbon dioxide can be a highly efficient and rapid removal of the odour.
Advantages: can efficiently and quickly remove a variety of breath (efficiency of 99%), widely used, simple manipulation, low investment costs.
Enameled wire workshop exhaust treatment water bath cyclone method: exhaust gas into the cyclone device, with a speed of about 18 m / s and 450 angle impact on the water surface, and drive the surface of the water to rotate to form a water mist and exhaust gas mixing, so that the organic matter in the exhaust gas is dissolved in the water, after the three-stage spraying device to clean up the pollutants most of the removal to ensure that the discharge standards.
Advantages: efficient dust removal, dust removal efficiency of 97% or more. Ensure the effect of the subsequent treatment process.
