Description
Technical Field
The invention relates to the technical field of volatile organic waste gas treatment, in particular to a movable waste gas incineration device for treating volatile organic gas.
Background
When petroleum refining and petrochemical devices are normally produced, VOCs are mainly discharged through organized treatment facilities and are basically in a controllable state. In order to ensure safe, stable and economic operation, the petroleum refining and petrochemical devices generally carry out one-time parking maintenance in 3-5 years, the parking time is 30-60 days each time, the discharge amount of VOCs in the process is far greater than the discharge amount of VOCs in normal production, the discharge amount is about several times or even dozens of times of the normal discharge amount, and the discharge amount of the VOCs is generally called abnormal discharge. The main sources of abnormally discharged VOCs include: (1) discharging in the process of stopping and decompressing the device; (2) purging, cooking, cleaning and discharging equipment and pipelines; (3) parking, overhauling and discharging the environmental protection facilities; (4) before starting, the device replaces and fills the waste gas that produces; (5) and (4) emission in the process of driving debugging. Because: (1) the VOCs cannot be treated due to the parking maintenance of the environmental protection equipment; (2) for the waste gas to be subjected to flare treatment, it is required that the calorific value should not be lower than 7880kJ/Nm3The oxygen content is not more than 2%, and the exhaust gas which is abnormally discharged is difficult to meet the conditions, so that the exhaust gas is discharged into the existing torch to be treated and has larger obstruction; (3) the discharge of part of VOCs is dispersed, the components are different and the discharge is temporary, and the like, at present, no effective method for treating the part of VOCs exists in China, and environmental regulations for treating the VOCs are increasingly strict, so the control for the discharge of the abnormally discharged VOCs is reluctant.
The existing VOCs treatment methods mainly comprise adsorption, absorption, catalytic oxidation methods, direct combustion methods and the like. The adsorption method is to utilize adsorbents such as active carbon and clay with adsorption capacity to adsorb the organic waste gas solvent, and the treatment method is simple and easy to implement, but has a plurality of problems: the adsorbent cannot be regenerated and recycled, and must be replaced after reaching adsorption saturation, so that not only industrial solid waste is generated and the operation cost is increased, but also the waste activated carbon is rich in a large amount of organic matters and can generate potential safety hazards such as combustion, pollutant release and the like under certain conditions. When the device is used for treating the abnormally discharged VOCs, the device is extremely easy to saturate and low in treatment efficiency, and is not suitable for the working condition that the high-concentration waste gas is easily discharged abnormally. The absorption method also has the above-mentioned problems.
The catalytic oxidation method has high treatment efficiency on VOCs, but the catalyst has high selectivity, poor universality and easy inactivation, so the method is not suitable for treating the abnormally discharged VOCs with complex and variable waste gas components and concentrations. And the catalytic oxidation device is huge and is usually fixed on a civil foundation or a steel structure platform, so that the application of the catalytic oxidation device under the abnormal emission working condition is limited.
CN103394270A discloses a portable integral type organic waste gas processing apparatus, the device is based on the design of adsorption concentration-catalytic oxidation method, utilizes the electrical heating to heat fresh air and form desorption wind, carries out desorption regeneration to the runner adsorption bed, and the organic waste gas after desorption gets into the catalytic combustion bed reaction and generates carbon dioxide and water after heating and the heat transfer, and the organic waste gas after the medium temperature flue gas of production utilizes the heat exchanger preheating desorption, saves the operation energy consumption. The device is designed based on the catalysis principle, and the catalyst has high selectivity and is easy to inactivate, so the device is not suitable for treating abnormally discharged VOCs.
