Oil gas discharging treatment system

Abstract

The invention discloses an oil gas discharging treatment system, comprising a safety shut-off valve connected to the down stream of an exhaust port of oil gas equipment, a main pipeline communicates with the down stream of the safety shut-off valve, and centrifugal fans are arranged on the main pipeline; a total hydrocarbon concentration analyzer matched with the safety shut-off valve is arranged at an air inlet of each centrifugal fan, and an air outlet of each centrifugal fan communicates with a burning conveying pipeline; the down streams of the burning conveying pipelines are connected with heating furnaces in a one-to-one correspondence mode, and anti-backfire assemblies positioned on the up streams of the heating furnaces are arranged on the burning conveying pipelines; and if the total hydrocarbon concentration analyzers detect that the content of the total hydrocarbon in the main pipeline is lower than 2%, the safety shut-off valve is kept in an on state, and if the total hydrocarbon concentration analyzers detect that the content of the total hydrocarbon in the main pipeline is not lower than 2%, the safety shut-off valve is disconnected, so as to prevent oil gas from flowing into the main pipeline. The oil gas discharging treatment system can effectively control the content of the total hydrocarbon in the discharged exhaust gas.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment of oil refining equipment, in particular to an oil gas discharge treatment system. Background technique [0002] During the refining, storage and transportation of petroleum products, a large amount of oil and gas will volatilize into the atmosphere, causing serious pollution to the surrounding environment. And affect the health of operators, causing malignant diseases such as cancer. In addition, it also causes a waste of resources. Therefore, the waste gas treatment of oil refining equipment has been widely concerned by the petrochemical industry. [0003] At this stage, the more common treatment processes for the exhaust emissions of oil refining equipment mainly include absorption method, adsorption method, condensation method, membrane separation method and combustion method. The treatment effect is not satisfactory, especially the total hydrocarbon content in the exhaust gas c...

Problems solved by technology

[0003] At this stage, the more common treatment processes for the exhaust emissions of oil refining equipment mainly include absorption method, adsorption method, condensation method, membrane separation method and combustion method. The treatment effect is not satisfactory, especially the total hydrocarbon content in the exhaust gas cannot be reasonably and effectively controlled, resulting in the total hydrocarbon content in the exhaust gas from oil and gas recovery equipment and other equipment exceeding the standard, unable to meet the national emission standards, and causing serious damage to the factory equipment. The continuous operation of the enterprise and the environmental protection work around the enterprise have adverse effects
