The utility model is described in further detail below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structure diagram of the new energy-saving control device of blower of the utility model.
Fig. 2 is the control logic figure of new energy-saving control device of blower shown in Fig. 1.
Fig. 3 is wind pressure-air quantity characteristic graph of new energy-saving control device of blower wind turbine shown in Fig. 1.
Specific embodiment
The structure of the new Conversion Regulating Speed ＆ Energy Saving of Fan control device of the utility model shows by the embodiment of Fig. 1, main portion
Part takes away panel and can see that, double dot dash line expression cabinet shape, and the touch LCD screen 2 on cabinet front panel is because be not easy
It expresses and is placed on side.Cabinet backboard lower part air inlet 11 connects the air intake passages such as installation bellows through screw hole, if cabinet leans on
Thirty years of age of wall can be connected directly and through walls with circular strip lange fitting head.First under the predetermined parameter setting of touch LCD screen 2
The signal of communication of frequency converter 1, frequency converter mainboard feedback gas sensor 1 and gas sensor 25 is run, while through frequency conversion
Device driving plate starts the motor of centrifugal blower 7；Without processed fresh air outside the suction of air inlet 11, through in cabinet
Air passage enters board-like medium effeciency filter 8（Select non-woven fabrics F6）With primary filter 9（Select G4）, wind turbine 7 in fresh wind port 4 simultaneously
It sends out through high efficiency particulate air filter 6（Select HEPA class ultra-fine fibre glass paper H12）High-quality air.Filter element is using reciprocating
Paper folder is folded into V-arrangement, and specific surface area is sufficiently large, effectively obstructs pellet PM10, fine particle in outdoor air
PM2.5, ozone O3, indoor carbon dioxide CO2, filter plate mount structure is convenient for replacement after backboard dismounting and safeguards.Enclosure top goes out
Air port is designed using strip mesh, and the present embodiment air-out area reaches 109368mm2.Bottom is set using concealed adjustable lower margin
Meter, entrance hole use Seal Design, prevent untreated contaminated from going out.
In fig. 2, for HD to set low-limit frequency, HG is setting highest frequency；1 minimum output frequency of frequency converter is 20HZ,
1 highest output frequency of frequency converter is 50HZ.When workload change, the motor of driving wind turbine 7 is adjusted, rotating speed becomes therewith
Change, power consumption can be reduced, save electric energy.From Hydrodynamics Theory, fan delivery Q is directly proportional to the first power of rotating speed n, wind pressure
P and rotating speed n's is square directly proportional, and shaft power N is directly proportional to 3 powers of rotating speed, i.e.,：
Q1/Q2=n1/n2 P1/P2=(n1/n2)2 N1/N2=(n1/n2)3
In formula：
Q1- rotating speed n1When air quantity（m3/s）；
Q2- rotating speed n2When air quantity（m3/s）；
P1- rotating speed n1When wind pressure（pa）；
P2- rotating speed n2When wind pressure（pa）；
N1- rotating speed n1When power（kW）；
N2- rotating speed n2When power（kW）.
Therefore, when working-flow required airflow is reduced, adjusting rotating speed decline can be such that power reduces very much.For example, work as
When air quantity drops to 90% with rotating speed, power will be reduced to the 73% of rated power；When air quantity and rotating speed drop to 80%,
Power will be reduced to the 51% of rated power；When air quantity and rotating speed drop to 70%, power will be reduced to rated power
34%；When air quantity and rotating speed drop to 60%, power will be reduced to the 21% of rated power.
The wind pressure of wind turbine shown in Fig. 3-air quantity characteristic graph can illustrate above-mentioned energy-saving principle, n1It is wind turbine in volume
Determine characteristic during rotating speed operation；n2For characteristic of the wind turbine in fall-back；R1For pipeline of fans resistance minimum when resistance it is special
Property；R2Drag characteristic during a certain array is increased to for pipeline of fans resistance.Wind turbine 7 is in characteristic curve of pipeline R1During work, work
Point is A, and flow and pressure are respectively Q1And P1, the power proportional needed for wind turbine is in Q at this time1And P1Product, that is, be proportional to
AP1、OQ1Area.Since manufacturing technique requirent air requirement is from Q1It is reduced to Q2When, it is actual if reducing damper aperture
The resistance of upper tube webmaster increases, and the operating point of wind turbine is made to move on to R2On B points.As can be seen that air quantity declines, wind pressure increases, and wind pressure increases
Greatly to P2, the at this moment power proportional Q needed for wind turbine2And P2Product, that is, be proportional to B P2、OQ2Area.Needed for obvious wind turbine
Changed power is few, although the control of this regulative mode is simple, is unfavorable for energy saving.According to frequency control, rotation speed of fan by
n1Drop to n2, do not change resistance of pipe system, at this moment operating point moves on to C points by A points, and flow is still Q2, pressure is by P1Drop to P3, at this moment
Power proportional needed for frequency control rear fan is in Q2With P3Product, that is, be proportional to C P3、OQ2Area, work(as seen from Figure 3
The reduction of rate is apparent.
Thus prove, after new wind turbine uses frequency converter timing, achieve significant power savings, be a kind of preferable speed governing
Control mode, and after the rotating speed reduction of machinery, mechanical abrasion is reduced, and service life extends, while equipment is reliable
Property improve, extend equipment overhaul cycle, reduce maintenance and maintenance cost, direct economic effect indirect economic effect is all very considerable.
As it can be seen that variable-frequency control technique can obtain good runnability and significant energy-saving effect for air-blower control.
Obviously, the quantity of filter determines the size of cabinet, and 7 rated power of wind turbine determines purification efficiency, and per small
When how many square metres Clean air delivery rate determine be applicable in area.Except field of employment described above, equally applicable one after miniaturization
Determine the family of scope, villa is selected rather than limitation in any form is done to the utility model, those skilled in the art can be
Impose various equivalent changes and improvement on the basis of above-described embodiment, all equivalent variations done within the scope of the claims or
Modification, should all fall within the scope of protection of the utility model.
