Description
Technical field
The present invention relates to environmental protection and field of energy-saving technology, particularly relate to a kind of dedusting with automatic speed regulating function
Blower and its operating method.
Background technique
Currently, bag filter has all obtained extensively in all trades and professions as environmental protection increasingly obtains the attention of various aspects
Using the power consumption of dedusting fan also accounts for the biggish specific gravity of energy consumption, in recent years for energy-efficient needs, the power-saving technologies such as frequency converter
Also it is widely used, but since general 1 deduster needs to service multiple except dirt pits, simple speed regulation is difficult to meet each
Except the dust removal requirement of dirt pits, therefore many dedusting fans still take the mode of constant speed operation, this necessarily leads to dust collection capacity
Long-time is rich, waste of energy, in addition if all dust removing valves are closed, there is the danger collapsed in deduster and cleaning shaft,
Have to thus the normally open for keeping certain dust removing valves, energy waste is more serious.
Summary of the invention
The technical problem to be solved by the present invention is to propose a kind of there is automatic adjust the shortcomings that for the above prior art

(2) dedusting branch pipe opens corresponding dedusting valve as needed, is then turned on dedusting fan, so that dedusting fan starts
Work, the dedusting fan after unlatching are connected dedusting branch pipe, are dusted according to the open and-shut mode of each dedusting valve；
The open and-shut mode of (three) 4 dedusting valves shares 16 kinds of combinations, and corresponding velocity coeffficient also has 16 kinds of combinations (such as table 1),
Indicated respectively with X1-16, Y1-16, Z1-16, W1-16, according to the diameter of corresponding dedusting branch pipe and consider the length of pipeline because
Element, calculates initial value, calculation formula be Q=k*n2(blower flow Q and fan speed it is square directly proportional), formula calculates
X1=0.1, Y1=0.4, Z1=0.2, W1=0.3 out, and be 1 multiplied by blower normal speed, the setting speed for obtaining blower is equal to
Normal speed；
(4) further according to field adjustable, final accurate initial value is obtained, X1=0.1, Y1=0.35, Z1=0.2, W1=0.3, so that
The numerical value fully meets the requirement except dirt pits, fixes these numerical value, and the blower setting speed calculated at this time is normal speed
0.95, using same method, obtains X10=0.03, Y10=0.05, Z10=0.15, W10=0.27, and so on and then obtain
This 16 groups of data of X1-16, Y1-16, Z1-16, W1-16；
(5) by data inputting control system of dust removal fan, program calculates blower according to the switch state of each dust removing valve automatically
Setting speed, setting speed=(X1 ... i+ Y1 ... i+ Z1 ... i+ W1 ... i) * normal speed, at this time dedusting fan can from
It is dynamic to be dusted according to the switch state of dedusting valve.
It is using technical solution of the present invention beneficial effect: according to the technical solution of the present invention, the first dedusting in the present invention
Branch pipe, the second dedusting branch pipe, third dedusting branch pipe and the 4th dedusting branch pipe length and caliber can be respectively according to dedusting
Demand is set, and control system of dust removal fan is equipped in dedusting fan ontology, and the switch state of dedusting valve accesses to dedusting wind
Machine control system, and each dedusting valve difference open and-shut mode is carried out permutation and combination by practical use, and sets corresponding, satisfaction
The velocity coeffficient of dirt pits dust removal requirement is removed at scene, then the velocity coeffficient of each dedusting valve is summed, multiplied by dedusting fan
Normal speed obtains speed setting value, and control system of dust removal fan control blower is run according to setting value, facilitates work people
Member realizes automation speed regulation, and the source that dedusting fan setting speed is calculated in the present invention is scene respectively except the practical dedusting of dirt pits
Demand, therefore the speed calculated can satisfy the dust collection capacity requirement in various situations, automatically adjust blower on this basis
Speed, can be energy saving to the maximum extent, and structure is simple, easy to use, and is mainly implemented in software, and is not required to throw substantially
Money can satisfy the demand in terms of environmental protection, energy conservation, equipment safety, reduce cost of labor and the labor intensity of staff,
It is time saving and energy saving, it is energy-efficient.
