Abstract
The utility model relates to electric control equipment, in particular to an environment-friendly dedusting fan control system applied to steel works. The environment-friendly dedusting fan control system comprises an electric control cabinet (1) and a cabinet door (14) arranged on the electric control cabinet (1), and is characterized in that: a main power switch (2), a frequency converter (4), a wind speed sensor (9), a temperature sensor (10) and a parameter measuring cavity (15) are arranged in the electric control cabinet (1); the cabinet door (14) is provided with a touch screen (12); the main power switch (2) is connected with the frequency converter (4) through a lead; a programmable logic controller (6) is connected with the frequency converter (4), the wind speed sensor (9), the temperature sensor (10) and the touch screen (12) respectively through leads; a lead (13) is led out of the frequency converter (4); and the wind speed sensor (9) and the temperature sensor (10) are arranged in the parameter measuring cavity (15). According to the control system, a plurality of plans can be preset according to own production tasks (the quantity of running steel furnaces) of works; and the control system is called directly during production, so that energy is saved to the maximum extent while optimization of an environmental protection effect is achieved.
Description
Technical field
The utility model relates to a kind of electrical control equipment, especially is applied to the Environmental-protecting dust-removing blower fan control system of steel mill.
Background technique
In the driving control of Environmental Protection at Steel Works dedusting fan, production task (quantity of driving the steel stove is different) load is just different, so the power that needs is just different.In traditional air-blower control, fan motor is in case starting, just move with rated velocity, regardless of what (opening the quantity of steel stove) of production task, fan motor all is that just formed: in production task many (quantity of driving the steel stove be'ss many) situation, it is inadequate that air quantity seems again with the rated velocity operation, blast does not reach the requirement of environmental protection, and dust removing effects is bad; In production task few (quantity of driving the steel stove be'ss few) situation, air quantity is large again, blast is superelevation again, although dust removing effects is good, wasted really a large amount of electric energy, and the blast of superelevation is to carrying grey pipeline, the cloth bag of dust chamber all is a danger, the time superelevation blast is arranged to carrying grey pipeline, dust chamber's cloth bag produces the phenomenon of destroying and occurs, changing filter bag also is a no small investment to steel mill.The factory that has also transforms dedusting fan, change greatly little, separately control, but do so a lot of drawbacks are still arranged: 1. large motor changes small motor, and itself being exactly wastes electric energy (small motor efficient does not have large motor height), 2. overlapping investment, waste money, 3. because be that power is split pole control, speed and pressure-regulating also is that the utmost point is arranged so, can not realize the stepless time adjustment pressure regulation.
Summary of the invention
The utility model aim to provide a kind of can be by default output frequency control motor speed, thereby realize the needed blast of output, the control system of saving power.
Environmental Protection at Steel Works dedusting fan control system of the present utility model, comprise electrical control cabinet 1 and cabinet door 14 disposed thereon, comprise main power switch 2, frequency variator 4, air velocity transducer 9, temperature transducer 10, parameter measurement chamber 15 in the electrical control cabinet 1, on the described cabinet door 14 touch screen 12 is set; Main power switch 2 connects frequency variator 4 by wire, programmable controller 6 connects respectively frequency variator 4, air velocity transducer 9, temperature transducer 10, touch screen 12 by wire, frequency variator 4 is drawn wire 13, and air velocity transducer 9, temperature transducer 10 are arranged in the parameter measurement chamber 15.
Programmable controller 6(PLC) is connected with touch screen 12, by touch screen 12 various parameters are set and are transferred to programmable controller 6(PLC), programmable controller 6(PLC) signal with correspondence transfers to frequency variator 4, be connected to blower fan by frequency variator 4 by the wire 13 of drawing, realize the control of blower fan; Factory can preset according to the product of oneself multiple set meal, can call different set meals according to what (open steel stove what etc.) of production task and satisfy environmental protection to the requirement of airflow pressure; This product arranges air velocity transducer 9 simultaneously, temperature transducer 10, parameter measurement chamber 15 is communicated with carrying grey pipeline, by air velocity transducer 9, temperature transducer 10 is the wind speed that detects, the parameter Real-time Feedbacks such as temperature are to programmable controller 6(PLC), programmable controller 6(PLC) calculates analog output control frequency variator output frequency, blast is stabilized near the setting value, thereby steady wind pressure, avoided high blast pipeline to be formed the danger that destroys, and few in blow-on, realized in the little situation of air requirement energy-conservation so that this control system has realized intellectuality fully.
This new control system, factory can preset multiple set meal according to the production task (open steel stove what etc.) of oneself, directly calls just passable during production.Like this, realized in the optimized while of satisfying environment protection effect, energy-conservation to greatest extent.
