Controller PLC system, miniature relay and wire connection terminal composition.
The present invention is automatically controlled by core realization of programmable controller PLC system, and multiple burners are in a closed combustion
Indoor automatic ignition, the burning of flame size automatic conversion are burnt, under small fire state, when tank liquor temperature reaches setting peak,
Two burner combustions can be automatically stopped, when tank liquor temperature is less than setting value, reset automatically two burners.
Control feature of the present invention is
By programmable controller PLC system system control is carried out for core.
Operation and display terminal are used as using touch screen, PLC is represented with touch screen tie-portion using communication modes
Connection
Frequency converter rotating speed is adjusted by PLC, so as to make combustion system in different conditions, fired state, large and small fire state
Under, obtain different wind pressure.
4. ignition controller igniting and gas electromagnetic valve is controlled to open or close by PLC.
5. by PLC and each protection signal, the connections such as flame sensing signal, gaseous-pressure signal, so as to make entirely to control
System can safe and reliable operation.
6. it is connect by PLC with fluid temperature signal and the communication of PLC and touch screen connects, so as to fulfill temperature-controllable.
The present invention includes step is implemented as follows:
(1)Igniting
Sequential control is carried out for core by programmable controller PLC system, presses the start button of switch board, first wind turbine
High speed purging is carried out to convergent current type pickling liquid heat exchanger apparatus, after purging, wind turbine reduction of speed to fire speed, then 1#Point
Fiery controller sparking, while 1#Gas ignition solenoid valve is opened, and then 1#Burner ignition detects flame, lights a fire successfully;
After flame stabilization 8 seconds, 4#Burner starts to light a fire, equally to 2#、3#Burner ignition, in ignition process, if lighting a fire
When, certain burner ignition failure, PLC system automatically cuts off gas electromagnetic valve and carries out second automatically and lights a fire;When second point
Fire failure, combustion system stop igniting and burning, carry out system protection, cut off gas valve, and wind turbine carries out high speed purging;

Present invention solves the technical problem that:
1st, multiple burners in ignition process because the reasons such as air pressure interfere with each other problem:By repetition test, determine
Combustion gas main pipeline inlet pressure≤5KPa;Utilize frequency converter timing function point analysis wind pressure size;Utilize gas pipeline ball valve tune
Node fire gas flow.Combustion flame is made to reach optimum efficiency (i.e. if burner ignition flame is small, easily by repetition test
It is put out during by other burner ignitions;If burner ignition flame is big, when burner easily lighted other, puts out).
2nd, multiple burners are in aflame stability and economy:When gas-operated thermal bath facility is in tank liquor keeping warm mode
When, burner is variation in closed combustion chambers burn temperature, if combustion flame frequently changes, air-fuel ratio is not easy to be transferred to most
It is good, cause fuel gas buring insufficient, that is, waste combustion gas makes exhaust emissions not up to standard again.So we use in normal operation,
Only big fire and small fire is burnt two kinds of states, and small fire only has a combustion gas to be in charge of to give burner gas supply when burning;When big fire is burnt
When, there are two combustion gas to be in charge of gas supply.This mode is easily transferred to air-fuel ratio most preferably.And under small fire state, work as tank liquor temperature
When reaching setting peak, two burner combustions can be automatically stopped.When tank liquor temperature is less than setting value, reset automatically
Two burners.It can guarantee that tank liquor temperature fluctuation is small, and saves combustion gas in this way.
Beneficial effects of the present invention:
Realize multiple burners automatic ignition, the burning of flame size automatic conversion in a closed combustion chamber, and reliable
Operation, makes convergent current type pickling liquid heat exchanger apparatus obtain practical application in wire rod acid pickling phosphating slot, hot water storgae.Present invention control
Fluid temperature precision processed is high, and chamber temperature is uniform, heat exchanger apparatus long lifespan, and the thermal efficiency has good up to 85 more than ﹪
Economic benefit and social benefit.The control system of the present invention is easy to operate, need to only light a fire reliable by start button, operation
Steadily, the safe thermal efficiency is high, remarkable in economical benefits.
