Automatically the detection of steam quality and regulation and control, be equipped with the regulation valve controlled by signal controller on each branch road.
Its duty is described further by the present invention below in conjunction with accompanying drawing:
Embodiment 1:
As it is shown on figure 3, this path is made up of branch road I and branch road II, main purpose is to reduce steam quality, steam generator go out
The steam part come carries out desuperheat humidification via attemperator, and another part is directly communicated to air collector and from attemperator steaming out
Vapour converges.From air collector steam out, first measure through drimeter, subsequently enter gas utilization unit.
Embodiment 2:
As shown in Figure 4, this path is made up of branch road I and branch road III, and main purpose is to improve steam quality, and steam is partly into
Steam-water separator, makes steam quality improve, and converges in air collector with steam generator steam out.From air collector
Steam out, first measures through drimeter, subsequently enters gas utilization unit.
By pipeline steam mass dryness fraction regulation and control each equipment of measurement system, pipeline, pipe fitting and valve are selected, establish
Detailed pipeline steam mass dryness fraction Modulation Measurement System, as shown in Figure 1.This system is by steam generator, attemperator, steam-water separation
Device, air collector, drimeter, signal controller and supporting jet chimney composition.
By technique scheme, the detection of steam quality can be realized and effectively control.When steam is sent to loosening and gaining moisture etc.
When steam quality requires low operation, open branch road I and branch road II, close branch road III, pipeline steam is carried out humidification process, from
And obtain relatively moist steam.It is sent to the steam quality such as cut tobacco cylinder dry when steam when requiring high operation, opens branch road I and branch road
III, close branch road II, pipeline steam is carried out dehumidification treatments, thus obtains relatively dry saturated steam.In a word, branch road I is in normally open,
Steam quality value according to drimeter actual measurement compares with mass dryness fraction value needed for gas utilization unit, continuous handoff leg II and branch road III, and
By valve regulated steaming amount, it is achieved the mixing of different proportion steam quality.Dry, moist steam is sufficiently mixed slow in gas collecting tank
Punching, enters gas utilization unit via steam calorimeter after measuring.The outlet conduit of air collector is provided with drimeter, can measure full
With pressure, flow, temperature, density and the mass dryness fraction of steam, the mass dryness fraction after processing, flow, the signal such as temperature is sent to signal control
Device processed, by comparing with pre-set mass dryness fraction, flow, temperature signal, sends feedback signal respectively, controls motorized adjustment
Valve, regulates each bypass flow size, makes the mass dryness fraction of output steam, flow, and temperature reaches to specify requirement, thus realizes steam quality
Automatically detection and regulation and control.Table 1 and table 3 obtain after modulating via branch road I and branch road II for the steam that steam generator produces
Data, table 2 is the cooling water parameter that in branch road I, attemperator is passed through.Understanding, after steam is humidified via branch road I, steam quality can drop
Low by 10.0% ~ 11.0%；After steam dehumidifies via branch road II, steam quality can promote 15.0% ~ 22.9%.
