Combined oil-gas recycling apparatus

Abstract

The invention provides a combined oil-gas recycling apparatus. The combined oil-gas recycling apparatus comprises a waste gas main pipeline, wherein the waste gas main pipeline is connected with a waste gas inlet, the waste gas main pipeline is connected with a washing tower, the washing tower is connected with an active carbon adsorption apparatus, the active carbon adsorption apparatus is connected with a catalytic oxidation apparatus, a primary main valve is arranged between the washing tower and the active carbon adsorption apparatus, a secondary main valve is arranged between the active carbon adsorption apparatus and the catalytic oxidation apparatus, and the combined oil-gas recycling apparatus also comprises a primary branch pipeline, one end of the primary branch pipeline is connected with the washing tower, and a primary branch valve is arranged between the primary branch pipeline and a gas outlet pipeline of the washing tower; and the other end of the primary branch pipelineis connected to a secondary main valve on the secondary main pipeline, and the primary branch pipeline and the secondary main pipeline are communicated with external air by virtue of a secondary branch valve. By adopting the combined oil-gas recycling apparatus, an indirect operation field can be satisfied, and the frequent starting-stopping of the catalytic oxidation in the indirect field influencing the service life and causing energy loss can be reduced.

Description

technical field [0001] The invention relates to the field of oil and gas recovery, in particular to a combined oil and gas recovery device. Background technique [0002] Industrial waste gas refers to the general term for all kinds of pollutant gases that are discharged into the air during fuel combustion and production processes in the factory area. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid mist lead mercury, beryllium compounds, smoke and productive dust, which will pollute the air when discharged into the atmosphere. These substances enter the human body through the respiratory tract in different ways, some directly cause harm, and some have a cumulative effect, which will seriously endanger human health. Different substances will have different effects. [0003] Therefore, industrial waste gas cannot be directly discharged into the atmosphere. W...

Problems solved by technology

[0003] Therefore, industrial waste gas cannot be directly discharged into the atmosphere. Waste gas treatment must be carried out, and it can only be discharged after reaching the emission standard. Although common waste gas purification devices can be used to filter out particulate pollutants in the waste gas (such as dust and suspended particles, etc.), however, coating Exhaust gas produced by the packaging process and chemical raw material production process often contains volatile organic compounds and odors, but common exhaust gas purification devices cannot filter and purify these substances, making common exhaust gas purification devices only applicable to part of the exhaust gas treatment procedures, which greatly limits The applicability of commonly used exhaust gas purification devices
