Exhaust gas filter device in chemical equipment

Abstract

The invention discloses a waste gas filter device in chemical equipment, which belongs to the technical field of waste gas treatment, and includes a waste gas filter pipe and a circulation filter device. The waste gas filter pipe is arranged at the top of the circulation filter device. The particulate filter assembly, the pipeline assembly and the first sealing assembly, the pipeline assembly is connected to the exhaust gas filtering pipeline, the particulate filtering assembly is arranged inside the pipeline assembly, and the first sealing assembly is arranged inside the exhaust gas filtering pipeline; the present invention adopts the exhaust gas filtering pipeline The U-shaped setting converts the flow direction of the exhaust gas in the exhaust gas filter pipe. Combined with the structural settings of the particle filter assembly and the circulation drive assembly, the service time of the particle filter is extended, and the existing exhaust filter device is solved due to the long filter screen. Time use is easy to block so that frequent replacement is required, resulting in increased cost and poor continuous workability of the device, which reduces the filtration efficiency.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to an exhaust gas filtering device in chemical equipment. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially in chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries, etc., the exhaust gas emitted has a strong smell, which seriously pollutes the environment and affects human health. There are many types of exhaust gas, the physical and chemical properties are very complex, and the toxicity is not the same. The exhaust gas discharged from fuel combustion contains sulfur dioxide, nitrogen oxides, hydrocarbons, etc.; due to the different raw materials and processes used in industrial production, various harmful gases and solid wastes are discharged, containing various components such as heavy metals, salts, radioactive material.
