Embodiment Construction
[0022] Preferred embodiments of the present invention will be described in detail below.
[0023] The preferred embodiment of the invention provides a treatment method for harmful exhaust gas pollution, comprising the following steps in order:
[0024] Step [1] Filtration and dust removal: filter the harmful gas through the nanofiber filter to remove dust, wherein the diameter of the nanofiber is 300-500nm;
[0025] Step [2] Excimer photolysis purification: the waste gas treated in step [1] passes through multiple layers of TiO in turn under the condition of excimer-level ultraviolet beam irradiation 2 / polypropylene composite nanofiber membrane, which was treated by excimer catalytic photolysis.
[0026] Step [3] The exhaust gas treated in step [2] is introduced into the low-temperature plasma device through the air inlet, and a breakdown discharge is formed under the action of high voltage electricity, and an active mixture including charged particles, free radicals, and el...

Abstract
The invention provides a method for treating harmful exhaust gas pollution. The method comprises the steps: filtering, removing dust, performing excimer photolysis purification, performing plasma treatment and the like. A nanometer fiber filtering net is combined with a TiO2 / polypropylene composite nanofiber membrane, so that harmful waste gases can be efficiently treated. The method disclosed by the invention is easy to operate, stable in process operation, safe and high in reliability, and secondary pollution such as NOX and the like can be avoided. According to the treatment process disclosed by the invention, combination of pretreatment and end treatment is focused, the decomposition efficiency of the harmful waste gases can be over 99%, and the method is wide in application range and considerable in market prospects.
Description
technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a treatment method for harmful waste gas pollution. Background technique [0002] With the development of society, people's awareness of environmental protection is becoming stronger and stronger. On the one hand, economic development will inevitably produce a certain amount of pollution at the current stage of people's understanding; on the other hand, human progress has also put forward higher requirements for the living environment in which they live, and the masses have strong reactions to environmental pollution. Environmental protection departments at all levels have become more and more strict on the restrictions on pollutant emissions. How to achieve the unity of economic benefit and environment is a new problem faced by human beings. [0003] The emission of volatile organic compounds (VOC) in the production process is the chief culprit that pollutes the ai...
