Safety emergency discharging device for organic waste gas treatment system Technical Field The utility model belongs to the technical field of crossing of environmental engineering and safety engineering, and particularly relates to a safety emergency discharge device for an organic waste gas treatment system. Background The background technology of the emergency emission of the safety production of the organic waste gas treatment system mainly stems from the complexity, safety risk and strict requirements of policy and regulation of the treatment of industrial VOCs (volatile organic compounds), and is the result of the comprehensive effects of high pressure policy, technical bottlenecks, industry risks and economic benefits. The national 'air quality continuous improvement action plan' clearly requires strengthening the whole flow treatment of VOCs, local governments develop special law enforcement actions, punishment is carried out on enterprises which do not operate in a closed mode and are not provided with waste gas collecting and treating systems, the enterprise is forced to upgrade treatment facilities, and an emergency emission function is added. The traditional treatment technology has limitations, the combustion method (RTO/RCO) needs to maintain high temperature (above 780 ℃), has high energy consumption and is sensitive to the fluctuation of the concentration of waste gas, equipment idle burning is easy to cause under the intermittent discharge working condition, the fuel consumption is large, the economy is poor, the adsorption method (activated carbon/molecular sieve) adsorption material is easy to saturate, the frequent replacement cost is high (such as the dangerous waste treatment cost of the activated carbon), and the single technology is difficult to meet the discharge standard. The high-concentration VOCs waste gas easily reaches the Lower Explosion Limit (LEL), and the traditional equipment lacks an emergency pressure relief design, so that explosion accidents are easily caused.
