Problems solved by technology

[0003] However, in the process of exhaust gas treatment, it often happens that the nitrogen oxides in the exhaust gas are not completely disposed of, and the exhaust gas is discharged. In this way, the exhaust gas still containing a certain amount of nitrogen oxides will be directly discharged into the air, causing air pollution. Pollution

Abstract

The invention discloses selective emission equipment for nitrogen oxide-containing waste gas in industrial production, and the equipment comprises treatment equipment, wherein a gas inlet pipeline anda gas outlet pipeline are arranged on the treatment equipment, a grid basket is fixedly connected in the gas outlet pipeline, the grid basket is arranged close to the treatment equipment, a working layer is arranged in the grid basket, the working layer is connected with the gas inlet pipeline and the gas outlet pipeline, the working layer is made of a three-dimensional folded graphene nanosheetmaterial, a recycling hole is formed in one side wall of the air outlet pipeline and is far away from the treatment equipment, and a recycling pipe is fixedly connected to the outer wall of the air outlet pipeline and is arranged opposite to the recycling hole. According to the invention, the waste gas which still has a certain amount of nitrogen oxide after treatment can be selectively introducedinto the treatment equipment for retreatment, so the waste gas containing excessive nitrogen oxide is prevented from being directly discharged into the air to cause pollution, and the environment isprotected.

Description

technical field [0001] The invention relates to the technical field of industrial production, in particular to a selective discharge device for waste gas containing nitrogen oxides in industrial production. Background technique [0002] In modern industrial production work, various by-products will be produced, such as various waste materials and various exhaust gases, including various exhaust gases containing nitrogen oxides, such as nitrogen dioxide, which are located in the protection of external air safety To avoid damage to the external environment, the nitrogen oxides in the exhaust gas need to be treated before the exhaust gas is discharged, and the harmless exhaust gas can only be discharged after the treatment is completed. [0003] However, in the process of exhaust gas treatment, it often occurs that the nitrogen oxides in the exhaust gas are not completely disposed of, and the exhaust gas is discharged. In this way, the exhaust gas still containing a certain amo...
