Process and device for treating vulcanization waste gas on basis of low temperature plasma technology

Abstract

The invention relates to a process and device for treating vulcanization waste gas on the basis of a low temperature plasma technology. The device comprises injection type low-temperature plasma wastegas treatment complete equipment which comprises an injection fan, a pretreatment system is arranged at the downstream of the injection fan, a discharge system is arranged at the downstream of the pretreatment system, an injection system is arranged at the downstream of the discharge system and is connected with the discharge system and an air mixing box, a plasma generation region is independentfrom a reaction region, and potential safety hazards do not exist; the discharge module is pollution-free and is long in service life; barrier discharge is implemented by dual media, and the densityof generated plasma is high; treatment equipment is parallel to a waste gas pipe, waste gas collection and an exhaust fan are omitted, and the running power of an induced draft fan is reduced; the running cost is low; and through engineering test and examination, emission of non-methane hydrocarbons in the treated vulcanization waste gas is far lower than the state required standard which is 10 mg/m<3>, and the treatment efficiency exceeds 60%; and the odor concentration treatment efficiency exceeds 80%.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment equipment, in particular to a process and device for treating sulfurized waste gas based on low-temperature plasma technology. Background technique [0002] With the continuous development of social economy and the continuous acceleration of industrialization, environmental and energy issues have been paid more and more attention by people. The vulcanization process in the rubber industry will produce a large amount of vulcanization flue gas. The vulcanization flue gas has the characteristics of low concentration, large air volume, multi-component, difficult to separate, and contains tar and dust. The traditional treatment process can no longer meet the treatment requirements. [0003] Traditional treatment methods include absorption, adsorption, condensation and biological methods. The investment cost of activated carbon adsorption is low, and the treatment effect is good. It is the ...
