Problems solved by technology

The traditional method of purifying the main flue gas distribution flue gas is to rely on negative pressure and valves to adjust the distribution flow, but the price paid is that the flue gas flow into each reactor and dust collector is quite different, and the local pres

Abstract

The invention relates to a pipeline structure, in particular to the pipeline structure for equally distributing purifying smoke pipe air quantity, which ensures that the air quantity distributed into each branch pipe is uniform and the flow is stable. The pipeline structure comprises a total purifying smoke pipe, wherein at least two separating tubes are arranged on the total purifying smoke pipe; and the outlets of the separating tubes are communicated with reactors. The pipeline structure has the advantages that: the air quantity distributed into each reactor is ensured to be uniform by adjusting all the control valves to make the dynamic pressure value displayed on each pressure meter equal; and a deflector is used for adjusting the flow direction of smoke to ensure that the smoke flow rate is vertical upwards, is uniformly distributed on the cross sections of the reactors and does not deflect and cause turbulence. The pipeline structure can effectively improve the uniformity of the air quantity distribution in the total purifying smoke pipe, reduce the local damage due to pressing of a reactor tube section, avoid airflow turbulence caused by violent change of the flow rate and the flow direction of the smoke and reduce the abrasion of a tube wall and the breaking rate of aluminum oxide particles.

Description

technical field [0001] The invention relates to a smoke pipe structure, in particular to a pipe structure for evenly distributing and purifying the air volume of the smoke pipe to ensure that the air volume distributed to each branch pipe is uniform and the flow is stable. Background technique [0002] During the aluminum electrolysis production process, the electrolytic cell emits a large amount of flue gas, and the fluoride and dust contained in the flue gas are the main pollutants in the aluminum electrolysis plant. These pollutants are discharged into the atmosphere through the skylight of the electrolysis workshop and the chimney of the dry flue gas purification system, causing certain pollution to the local environment. Therefore, it is necessary to remove fluoride and dust from the electrolysis flue gas. [0003] The electrolytic flue gas purification system collects the electrolytic flue gas into the main purification flue pipe through the exhaust pipe of the electro...
