Description
Technical field
The present invention relates to glassware production technical field, more particularly, to a kind of glass furnace gas-air exchanges linkage control automatically
System processed.
Background technology
The shape of a hoof glass furnace coal gas and brethaid under normal operation fired state carry out one in 30-40 minute
Secondary burning switching, due to being all in the past in commutation with artificial, during commutating, after gas cutting, furnace pressure power and temperature
Rapid decline, now needs a large amount of gas-fireds to maintain kiln furnace pressure and temperature, to add that air enters the amount of combustion chamber not
Intake can be changed according to condition of commutation, in kiln, gas-fired is insufficient, the waste gas of generation is more, waste fuel.Due to
Temperature course response lag, carrys out fluctuation ratio to kiln furnace pressure temperature band larger, glass solution solute in kiln is had very big
Impact is directly connected to the product quality of glassware.And artificial cannot commutate at short notice again terminate after immediately enter steady
Determine state, be also unfavorable for that kiln economical combustion also speeds up kiln aging.
Content of the invention
In order to solve above-mentioned technical problem, provide a kind of control system that can extend kiln service life, gas saving,
The present invention provides technical scheme below：
A kind of glass furnace gas-air exchanges coordinated control system automatically, including PLC, with PLC input
The sensor of connection, touch-screen, the warning device being connected with PLC output end, driving actuator, connect with driving actuator
The coal gas exchanger that connects, brethaid, overfire air fan, water seal arrangement, temperature-adjusting device；Described sensor includes pressure and passes
Sensor, temperature sensor, level sensor.
The control system method of operation is：Swap time is set as 30-40min by touch-screen, first by PLC control
Coal gas exchanger is positive to be run, and detects whether to put in place by pressure sensor, if running not in place, starts coal gas low pressure alarming；
Prompting artificial treatment, after putting in place, stop alarm time delay 6-8 second control the positive operation of brethaid, and detect whether again
Position, if running now brethaid warning device not in place to be in warning, points out artificial treatment.After putting in place, stop alarm is secondary
Blower fan start or accelerate, after pressure sensor detect gas pressure normal after, coal gas low pressure all clear, work as temperature sensor
Detect kiln in-furnace temperature normal after, overfire air fan slow down or close；After 30-40min, control coal gas exchanger inverted running,
And detect whether to put in place, if running not in place, start coal gas low pressure alarming；After putting in place, the time delay 6-8 second controls brethaid anti-
To operation, and detect whether again to put in place, after putting in place, overfire air fan starts or accelerates, treats that pressure sensor detects gas pressure
After normal, coal gas low pressure all clear, when temperature sensor detect kiln in-furnace temperature normal after, overfire air fan slows down or closes
Close；Next cycle is entered after 30-40min.
Further, described sensor and PLC input is connected to by A/D converter, digital filter；
Described PLC output end passes sequentially through PID regulator, D/A converter is connected to driving actuator.The present invention adopts PLC
PID control realized by controller, has flexibility and adaptable feature.
Further, described temperature-adjusting device is air-conditioning so that keeping temperature constant state in kiln.
Further, described warning device is buzzer.
The beneficial effects of the present invention is：
（1）, solve the problems, such as manually cannot commutate at short notice terminate after immediately enter stable state, be conducive to extend kiln
Stove service life, gas saving；
（2）, thoroughly eliminate artificial commutation after there is exhaust residual and can not be discharged away in time in exhaust air chamber and be possible to
Cause to lose quick-fried major safety risks, thus ensure that the safe operation of kiln.

Specific embodiment
A kind of glass furnace gas-air as shown in Figure 1 exchanges coordinated control system automatically, including PLC, with
The sensor of PLC input connection, touch-screen, the warning device being connected with PLC output end, driving execution
Device, with the coal gas exchanger driving actuator to be connected, brethaid, overfire air fan, water seal arrangement, temperature-adjusting device；Institute
State sensor and include pressure sensor, temperature sensor, level sensor.Described sensor and pass through A/D converter, numeral
Wave filter is connected to PLC input；Described PLC output end passes sequentially through PID regulator, D/A converter even
It is connected to driving actuator.The present invention realizes PID control using PLC, has flexibility and adaptable feature, described
Temperature-adjusting device is air-conditioning so that keeping temperature constant state in kiln；Described warning device is buzzer.
The control system method of operation is as shown in Figure 2：Swap time is set as 30-40min by touch-screen, is first controlled by PLC
Device processed controls the positive operation of coal gas exchanger, and detects whether to put in place by pressure sensor, if running not in place, starts coal gas
Low pressure alarming；Prompting artificial treatment, after putting in place, stop alarm time delay 6-8 second control the positive operation of brethaid, and again
Detecting whether to put in place, if running now brethaid warning device not in place to be in warning, pointing out artificial treatment.Stop after putting in place
Only warning overfire air fan start or accelerate, after pressure sensor detect gas pressure normal after, coal gas low pressure all clear, when
Temperature sensor detect kiln in-furnace temperature normal after, overfire air fan slow down or close；After 30-40min, control coal gas exchanger
Inverted running, and detect whether to put in place, if running not in place, start coal gas low pressure alarming；After putting in place, the time delay 6-8 second controls sky
Gas exchanger inverted running, and detect whether again to put in place, after putting in place, overfire air fan starts or accelerates, treats that pressure sensor detects
To gas pressure normal after, coal gas low pressure all clear, when temperature sensor detect kiln in-furnace temperature normal after, overfire air fan
