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
The present invention relates to a kind of smoke pipe structure, it is even to relate in particular to the air quantity that a kind of assurance is assigned in each arm, and the stable pipeline configuration that purifies the smoke pipe air quantity of dividing equally that flows.
Background technology
In the Aluminium Electrolysis process, electrolyzer gives out a large amount of flue gases, and fluorochemical that contains in the flue gas and dust are the main pollutents of electrolytic aluminium plant.These pollutents in atmosphere, have caused certain pollution to local environment by potroom skylight and the smoke stack emission of dry method flue gas purification system, therefore must carry out defluorination and smoke harnessing to electrolysis flue gas.
The electrolysis flue gas purification system is aggregated into electrolysis flue gas by the electrolyzer smoke exhaust pipe and purifies in total smoke pipe, is assigned to successively and adsorbs HF and dedusting in reactor and the fly-ash separator respectively, flue gas after being purified emptying behind induced draft fan, chimney.Therefore, reactor and fly-ash separator are the parts of core the most in the purification process, are the key links of decision purification system fluorochemical and dust discharge index height.The conventional approach that purifies total smoke pipe distribution flue gas is to rely on negative pressure and valve regulated dispense flow rate, but the cost of paying is the flue gas flow that enters each reactor and fly-ash separator differs bigger, the local crushing of reactor pipeline section is higher, and flow velocity size and direction change violent, the alumina particle of absorption HF is relatively poor in reactor internal diffusion effect, transducer wall ' s abrasion is serious, and the alumina particle percentage of damage is higher.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of pipeline configuration that purifies the smoke pipe air quantity of dividing equally, purpose is to guarantee that the air quantity that is assigned in each arm is even, and it is stable to flow.
The present invention is achieved through the following technical solutions in order to reach above-mentioned purpose: divide equally the pipeline configuration that purifies the smoke pipe air quantity, comprise purifying total smoke pipe, be provided with at least two pipes on the total smoke pipe of purification, the pipe outlet is communicated with reactor.
Described pipe is provided with control valve.
Described pipe is located at and purifies the direction of the interior exhanst gas outlet of total smoke pipe in face of flow of flue gas.
Be provided with flow deflector in the described exhanst gas outlet.
Described pipe is that welding, riveted joint or bolting are connected with flow deflector.
Described exhanst gas outlet is located at the top that purifies flue gas flow direction in total smoke pipe.
Described pipe cuts the radial section of total smoke pipe one by one along flue gas flow direction.
The pipeline of described reactor top is provided with tensimeter.
Advantageous effect of the present invention is as follows:
Adopt the present invention on the total smoke pipe of purification, to be provided with at least two pipes, the structure that the pipe outlet is communicated with reactor can effectively improve the homogeneity that purifies tolerance distribution in total smoke pipe, reduce the local crushing of reactor pipeline section, avoid flue gas flow rate size and direction to change violent and air-flow turbulence that cause, reduce the percentage of damage of transducer wall ' s abrasion and alumina particle.
By regulating all control valves the dynamic pressure value that shows on each tensimeter is equated, can better guarantee that the air quantity that is assigned in each reactor is even, flow deflector is in order to adjust the flow direction of flue gas, guarantee that flue gas flow rate vertically upward, uniform distribution on the cross section of reactor can not produce bias current and turbulence.
