The content of the invention
In order to solve the problem of that existing organic pollutant processing cost is high complicated for operation, provide one kind has the present invention The purifying treatment method of machine polluted gas.
The present invention technical solution be:A kind of method using organic gas processing unit purification air, this is organic Gas treatment equipment includes air inlet, controller and display screen, filter, snorkel, humidification device, mute exhaust fan, outlet Mouth, pedestal, air quality detector, air processor, shell;
Using ultraviolet lamp as core in air processor, the ultraviolet range that ultraviolet lamp is sent is:180nm≤wavelength≤ 260nm;
Controller and display screen are opened, by the way that mute exhaust fan is controlled to adjust gas flow rate, gas is made to pass sequentially through air inlet Mouth, filter, snorkel, humidification device, snorkel, air processor, gas outlet;
For gas when by air inlet and gas outlet, air quality detector can detect air quality, and in controller And display screen is shown;
When Gaseous Organic Pollutant content is exceeded, the ultraviolet lamp in automatic start air processor;When the organic dirt of gas When contaminating object content qualification, the ultraviolet lamp in air processor is automatically closed.
The Gaseous Organic Pollutant include C1-C12 alkane, formaldehyde, acetaldehyde, propionic aldehyde, benzene, toluene, ethylbenzene, methylbenzene, One or more organic pollutions in dimethyl benzene, ethyl methyl benzene.
The method of the purification air include that gas is continuously passed through facture, gas interval is passed through one kind in facture or It is a variety of.
The air processor increases reaction light path, can improve by increasing the length of ultraviolet lamp or the number of ultraviolet lamp Organic pollution gas purifying treatment effeciency.
The air processor inner surface increases the one or more set in reflective mirror or tinfoil, can improve ultraviolet lamp profit Use efficiency.
Increase an ozone filter after the method air processor of the purification air.
Oxidative free radical in atmospheric environment mostlys come from solar ultraviolet, cosmic ray and earth high-intensity magnetic field to it In gaseous material molecule powerful energy effect.Under artificial environment also can by excited gas molecule obtain plasma and then Obtain free radical.Therefore, the present invention creates oxidative free radical environment using the ultraviolet lamp of specific wavelength under artificial environment, makes Organic pernicious gas such as methane is purified and utilizes before environment is discharged into, and is asked so as to solve organic noxious gas emission pollution Topic.Organic gas first carries out humidification process before organic gas processing unit is entered simultaneously, is conducive to generate under artificial environment More free radicals have better treatment effect for organic pollutant.
Under the irradiation of specific wavelength ultraviolet light, covalent bond homolysis occurs air in described device for oxygen molecule and hydrone, It generates free radicals, with the free radical generated oxidation reaction occurs for organic pollutant, ultimately generates carbon dioxide, water.
Compared with existing scheme, major advantage is the solution of the present invention:The present invention provides simple, safety, low costs Processing method, oxidative safety is efficient, and product is pollution-free, and reaction condition is mild, simple economy, immediately efficiently handle rapidly it is organic Polluted gas has a extensive future.
