Variable diameter pipeline by n branch's exhaust gas source merge together with 1 central dust remover, 1 big exhaust fan, 1 mating frequency converter mould
Formula, that is, conventional central smoke harnessing mode is administered.
When n in big workshop divide workshop (i.e. n branch's exhaust gas source, n are generally 3-20) synchronous working rate >=80%
When, conventional central dust pelletizing system can carry out variable frequency adjustment by the matched frequency converter of big exhaust fan so as to energy conservation, therefore tradition

Drag overall value) it is fixed and invariable, when frequency converter, which is become smaller motor speed by frequency conversion, realizes energy conservation, exhausting quantitative change
Small, negative pressure value becomes smaller in a manner of square series, when the negative pressure value of exhaust fan does not overcome hindering along journey for branch's exhaust gas source enough
When force value, dedusting function is ineffective, and energy-saving and frequency-variable also just loses meaning.Therefore, the exhaust fan of conventional central dust pelletizing system becomes
Frequency be it is conditional, empirical value is >=80%.
Smoke harnessing mode, i.e. each 1 set of point workshop configuration independent branch's dust pelletizing system are dispersed using tradition, n points
Workshop (i.e. n branch's exhaust gas source, n=3-20) configuration n covers the governance model of independent branch's dust pelletizing system, divides vehicle when n
Between (i.e. n branch's exhaust gas source, n=3-20) synchronous working rate < 80% when, or even when only 20%, exhausting function is not present
Source wastes problem, still, have the defects that dispersion installation take up a large area, the defect of Decentralization inconvenience or due to sky
Between be restricted and can not carry out dispersion improvement completely.
As described above, for conventional central dust pelletizing system, existing serious as the synchronous working rate < 80% in each point of workshop

Specific embodiment
Embodiment one
Fig. 1 is the structure chart of the embodiment of the present invention one；Fig. 2 is the connection schematic diagram of equal wind apparatus；Fig. 3 is branch's exhaust fan
Connection schematic diagram.As shown in Figures 1 to 3, a kind of novel central dust pelletizing system, including 6 branch's exhaust gas sources, central dust remover,
The net gas escape pipe 4.2 of exhaust fan and exhaust fan frequency converter, central dust remover 4 is connect with net gas general pipeline 5, net gas general pipeline's 5
The corresponding 6 branch's exhaust gas sources in outlet are accordingly arranged 2,6 branch's exhaust fans 2 of 6 branch's fresh-air ducts 1 and branch's exhaust fan and set respectively
Frequency converter 3 is set, branch's exhaust gas valve 7 is respectively set on branch's flue gas leading 6 of 6 branch's exhaust gas sources, in 6 branch's fresh-air ducts
The net air valve 8 of branch, exhausting amount needed for the corresponding branch's exhaust gas source of the exhausting amount of branch's exhaust fan 2 are respectively set on 1
It is consistent.
The caliber of 6 branch's flue gas leadings 6 is unanimously set by per unit cross sectional product obtained air quantity, i.e. exhausted air quantity then caliber greatly
Greatly, the small then caliber of exhausted air quantity is small, and the caliber of 6 branch's fresh-air ducts is 1.2 to 1.3 times of the caliber of corresponding branch's flue gas leading,
I.e. net big, the net narrow-minded then caliber of large-minded then caliber is small, and the distance of pipeline is it has been determined that in order to reduce pipeline on-way resistance (section
Can), generally realized by reducing the method for wind speed；For exhaust pipe, the sedimentation due to being limited by dust is assembled, general wind
Fast design comparison is high, and for fresh-air duct road, the sedimentation aggregation of dust, which restricts, have been released, and general wind speed design comparison is low；But two
Person is limited by the restriction of space and cost, therefore, is empirically worth, general exhaust pipe wind speed 18m/s-24m/s；Fresh-air duct
Transportation work style speed 12m/s-14m/s, calculates like this, then exhaust pipe wind speed is 1.5 to 1.7 times of fresh-air duct transportation work style speed, then fresh-air duct
Basal area should be 1.5 to 1.7 times of flue gas leading basal area, then caliber should be 1.2 to 1.3 times.
Ideally, under unanimous circumstances, 6 branch's flue gas leadings 6 just can obtain the wind speed of 6 branch's flue gas leadings 6
To corresponding exhausting amount, however in actual use, it is also necessary to consider the on-way resistance value of 6 branch's flue gas leadings 6, even if 6
The wind speed of a branch's flue gas leading 6 is consistent, but when the on-way resistance value difference of 6 branch's flue gas leadings 6,6 branch's flue gas leadings 6 are obtained
Exhausting amount will be different；Therefore, in order to overcome drawbacks described above, the present invention distinguishes on branch's flue gas leading 6 of 6 branch's exhaust gas sources
Branch's regulating valve 10 is set, and the arrival end of branch's exhaust gas valve 7 is arranged in branch's regulating valve 10, and effect is to work as to actually use
When the on-way resistance value of a certain branch's flue gas leading 6 is inconsistent in journey, branch's regulating valve 10 is adjusted, makes its on-way resistance value
It is almost the same with the on-way resistance value of other branch's flue gas leadings 6.
The invention also includes a central control system and 6 branch-control systems, central control system is removed including center
The pulse jetting deashing control system and unloading valve control system of dirt device, 6 branch-control systems respectively with 6 branch's exhaust fans
2 and its net air valve 8 and 6 branch exhaust gas valve 7 of 3,6 branches of frequency converter be electrically connected.
Embodiment one further includes equal wind apparatus 9, branch's exhaust gas of the air inlet 9.1 and 6 branch exhaust gas source of equal wind apparatus 9
Pipe 6 connects；Shown in Figure 1, the central dust remover of embodiment one is separate unit deduster 4, the waste gas inlet of separate unit deduster 4
4.1 are directly connected to by connecting line 11 and the air outlet 9.2 of equal wind apparatus 9.Branch's flue gas leading of the invention, branch's fresh-air duct
Quantity can accomplish 3 to 20, branch's regulating valve of the invention, branch's exhaust gas valve, the net air valve of branch quantity can
To accomplish 3 to 20, specifically by depending on actual demand.
As shown in Fig. 2, wind apparatus 9 includes equal wind box, the top of equal wind box is cylindrical drum 9.3, equal wind box
Lower part is the taper cone barrel 9.4 being correspondingly connected with cylindrical drum 9.3, and closed unloading valve 12, equal wind dress are configured in 9.4 lower part of taper cone barrel
The upper surface of cylindrical drum 9.3 is arranged in the air outlet 9.2 for setting 9, and the air inlet 9.1 of equal wind apparatus 9 is arranged in 9.3 lower part of cylindrical drum
Side, branch's flue gas leading 6 of 6 branch's exhaust gas sources, which protrudes into after the air inlet 9.1 of equal wind apparatus to be bent downwardly, protrudes into equal wind
The taper cone barrel 9.4 of device, the sectional wind velocity≤3m/s on the top of equal wind box, i.e. sectional wind velocity≤3m/s of cylindrical tube 9.3.
Advantages of the present invention 1 is, the air inlet 9.1 of equal wind apparatus 9 generally in 90 ° downward, under such configuration, exhaust gas enters
After equal wind apparatus 9, firstly, since basal area sudden enlargement, wind speed suddenly falls to≤3m/s, most of big particle and again
Matter dust falls directly into ash bucket under the effect of inertia force and gravity, realizes the I grades of pre- dedustings of inertia force+gravity；Secondly, wind
Direction by change into downward upward, constitute " U " font path, must have a zero velocity point in the bottom in " U " font path, give up
In in gas-fine grained and heavy dust fall into ash bucket removal again, realize the pre- dedusting of gravity+zero velocity II grade.When dividing vehicle
Between unsaturated work when, it is lower that exhaust gas enters the sectional wind velocity after equal wind apparatus 9, therefore, equal wind and the pre- dedusting function of second level
Effect it is better.
Obviously, conventional central duster system and tradition dispersion dust pelletizing system do not have advantages of the present invention 1.
Advantages of the present invention 2 is that each branch's exhaust gas source (i.e. each point workshop) is correspondingly configured with 1 set of branch's exhaust fan
2 and frequency converter 3 therefore each divide the opening and closing of dust removal system for workshop completely can be independent, divide dust removal system for workshop
The increase or reduction for opening quantity, are adjusted according to production needs, can be real in the control cabinet in each workshop
It is existing, it manages very convenient.
Such as: employee has found that the dust pelletizing system pumping deficiency in draught in this point of workshop is much of that, can be by configuring in this point of workshop
Control cabinet and control system, increase the frequency of frequency converter, realize and increase exhausting amount.Employee has found the dust pelletizing system in this point of workshop
Exhausting amount is too big, can reduce the frequency of frequency converter, realization subtracts by the control cabinet and control system configured in this point of workshop
Few exhausting amount.Each divide the dust pelletizing system exhausting amount in workshop by the way that corresponding exhaust fan running frequency, Mei Gefen is arranged
The net air valve 8 of branch's exhaust gas valve 7 in workshop and branch corresponds, therefore the dust pelletizing system in any 1 point of workshop can be only
Vertical operation is closed.
When needing the dust pelletizing system in any 1 point of workshop of unlatching/closing, it is only necessary to divide dust removal system for workshop corresponding this
Branch's exhaust fan 2, the net air valve 8 of branch's exhaust gas valve 7, branch opens/closes simultaneously；Whenever, as long as there is 1
The dust pelletizing system in point workshop is working, and deduster group does not turn off, in shared state, only when a whole point workshops is removed
When dirt system is all closed, deduster group can just be closed.
Obviously, advantages of the present invention 2 acquires conventional central dust pelletizing system and installs that occupied area is few, centralized management side concentratedly
Just, concentrated dust-removing saves the advantageous points such as energy consumption, meanwhile, acquire the advantageous point of tradition dispersion dust pelletizing system decentralised control；Overcome
Conventional central dust pelletizing system central controlled defect, meanwhile, overcome tradition dispersion dust pelletizing system dispersion installation occupied area
Greatly, the defects of Decentralization is inconvenient or can not carry out dispersion improvement etc. completely due to limited space system.
Advantages of the present invention 3 is that the synchronous working rate in each point of workshop is smaller, and energy saving ratio is higher.
Such as when dividing the synchronous working rate in workshop≤50%, on the one hand, only≤50% branch's exhaust fan is working, separately
Exhaust fan outside >=50% can close, at this point, the power consumption values of exhaust fan can be significantly reduced to≤50%, that is, realize exhaust fan
Level-one energy conservation；On the other hand, due to central dust remover be it is shared, with substantially reducing (>=50%) for exhausting amount, center
The Resistance Value of deduster substantially reduces about 50% or so therewith, at this point, each branch's exhaust gas source need overcome along journey drag overall
Value is also followed and is substantially reduced, and branch's exhaust fan can realize second level energy conservation by branch's frequency converter frequency conversion.
Such case is for conventional central dust pelletizing system, due to by 1 set of big exhaust fan and frequency converter power consumption values saving rate <
80% limitation, the power consumption values of conventional central dust pelletizing system can not decline again, i.e., level-one fractional energy savings is limited by < 80%, in
Deduster shared second level power savings advantages in centre can not also embody.
Such case disperses dust pelletizing system for tradition, and level-one fractional energy savings, which obtains, adequately to be embodied, still, since there is no
Central dust remover, the shared second level power savings advantages of central dust remover are then absolutely not.
Advantages of the present invention 4 is that the synchronous working rate in each point of workshop is smaller, and efficiency of dust collection is higher.
Such as when dividing the synchronous working rate in workshop≤50%, on the one hand, (>=50%) is substantially reduced with exhausting amount, by
It immobilizes and shares in the filter area of central dust remover, at this point, filtration velocity significantly reduces, filter efficiency is significantly mentioned
It is high.
Such case is duplicate for conventional central dust pelletizing system.
Such case disperses dust pelletizing system for tradition, since there is no central dust remover and shared advantage, then completely not
There are this advantages.
