Abstract
The invention relates to a pipeline for controlling flue gas removal, particularly a structure for controlling the wind pressure balance of an aluminium electrolysis-based purification flue gas pipeline, comprising an electrolytic tank, wherein a flue gas removal branch pipe is arranged between the electrolytic tank and a purification main pipe, the purification main pipe is connected with a purification header pipe, the flue gas removal branch pipe is provided with a compensator and two insulation tubes, a reducer pipe is arranged between the two insulation tubes, the pipe diameter between the reducer pipe and the purification main pipe is equal to the minimum diameter of the reducer pipe, and the variations in the diameter from the nearest flue gas removal branch pipe to the purification header pipe to the farthest reducer pipe on the flue gas removal branch pipe to the purification pipe is gradually reduced. According to the invention, local turbulence and disturbed flow of air flow can be effectively avoided, the pressure lose of the pipes is reduced by about 150 Pa, and the effects of saving energy and reducing consumption of the purification system are really achieved. Compared with the traditional allocation of purification pipes, steel consumption is reduced after the diameter of the pipe is reduced, the sizes of other supporting components are correspondingly reduced, and thus the construction cost of the purification system is reduced.
Description
Technical field
The present invention relates to a kind of control smoke evacuation pipeline, relate in particular to a kind of structure of controlling aluminum electrolytic decontamination flue gas pipeline pressure balance.
Background technology
In recent years, along with the continuous increase of aluminum cell current intensity, the also corresponding increase of single groove exhaust smoke level.The one cover flue gas purification system exhaust gas volumn of collecting 80～120 electrolyzers approximately, air quantity how to realize each arm are divided equally and have just been become key.
Traditional method as illustrated in fig. 1 and 2 is on the export pipeline of every electrolyzer, to establish volume damper, like butterfly valve, push-pull valve or orifice plate etc., realizes purifying the pressure balance of pipeline with the local crushing of regulating the outlet section.But this method is bigger to the flow perturbation at place, outlet, has increased the pipeline crushing, has directly caused the energy consumption of purification system to rise.
Summary of the invention
For solving the problems of the technologies described above the present invention a kind of structure of controlling aluminum electrolytic decontamination flue gas pipeline pressure balance is provided; Purpose is the blast that balance purifies each arm of piping system; Effectively avoid the local turbulence and the flow-disturbing of air-flow, reduce the pipeline crushing, reduce the energy consumption of purification system.
For reaching the structure that above-mentioned purpose the present invention controls aluminum electrolytic decontamination flue gas pipeline pressure balance; Comprise electrolyzer; Electrolyzer and purification are provided with the smoke evacuation arm between being responsible for; Purify and be responsible for and the total pipe coupling of purification, on the smoke evacuation arm, be provided with loop expansion pipe and two insulation tubes, between two insulation tubes, be provided with adapter bonnet; Adapter bonnet equates with the minimum diameter of adapter bonnet with the pipeline diameter that purifies between being responsible for, apart from purifying the nearest smoke evacuation arm of house steward to reducing gradually apart from the adapter bonnet vary in diameter amplitude that purifies on house steward's smoke evacuation arm farthest.
One end of described adapter bonnet minimum diameter is connected with variable valve.
The variable valve of stating be push-pull valve or butterfly valve.
Advantageous effect of the present invention: on the smoke evacuation arm, regulate the outlet cigarette of each arm with the pipeline reducing
Tolerance is tending towards on average, can balance purifies the blast of each arm of piping system, can effectively avoid the local turbulence and the flow-disturbing of air-flow again, reduces the about 150Pa of pipeline crushing, plays the effect that purification system is saved energy and reduce the cost conscientiously.Compare the configuration of traditional purification pipeline, reduced rolled steel dosage behind the pipeline reducing diameter again, therefore the also corresponding gauge size of having dwindled of other auxiliary component has also reduced the construction cost of purification system.

Embodiment
Below in conjunction with accompanying drawing the present invention is described further, but protection scope of the present invention is not limit by embodiment.
The present invention controls the structure of aluminum electrolytic decontamination flue gas pipeline pressure balance shown in Fig. 3 and 5; Comprise electrolyzer 1, be provided with smoke evacuation arm 2 between electrolyzer 1 and purification are responsible for 3, purify the person in charge 3 and be connected with purification house steward 4; On smoke evacuation arm 2, be provided with loop expansion pipe 5 and two insulation tubes 6; Be provided with adapter bonnet 8 between two insulation tubes 6, adapter bonnet 8 equates with the minimum diameter of adapter bonnet 8 with the pipeline diameter that purifies between the person in charge 3, reduces gradually to the adapter bonnet 8 vary in diameter amplitudes that distance purifies on the house steward 4 smoke evacuation arm 2 farthest apart from purifying house steward's 4 nearest smoke evacuation arms 2; To satisfy the pressure balance requirement of different positions place smoke evacuation arm 2; Every section purification is responsible for 3 and is collected 10～20 electrolyzer 1 flue gases approximately, and every electrolyzer 1 is responsible for 3 through smoke evacuation arm 2 and purification and is communicated, and finally is summarized in purification house steward 4.
One end of adapter bonnet 8 minimum diameters among the embodiment 1 as shown in Figure 4 is connected with variable valve 7, and variable valve 7 is push-pull valve or butterfly valve, and variable valve 7 only cuts out and the complete opening two states.Other is with embodiment 1.
