Abstract
The invention belongs to the field of an electronic monitoring system, and particularly relates to a monitoring method for the resistance of a coke dry quenching recycle gas. A pressure P fan at an outlet of a circulating fan measures the P value of the air supply amount Q of the circulating fan in unit time as a reference value, and the P value is displayed on a display device of an electronic monitoring device, and if the P is greater than a set value P, the electronic monitoring device gives out an alarm signal. The resistance size of a system can be evaluated in time by adopting the monitoring method, so that the resistance change of the circulating gas system can be mastered in time so as to make preparation in advance.
Description
Technical field
The invention belongs to electronic monitoring and control system field, specifically a kind of dry coke quenching recycle gas resistance monitoring method.
Background technology
Dry coke quenching recycle gas system is that dry quenching system mainly exchanges thermal source and thermal source transfer system, and the propulsion source of the recycle system and recycle system resistance are the important factors affecting its heat exchange and heat transfer.The systemic resistance of recycle gas system is larger, will exchange and transmit same heat in the unit time, and recirculation blower needs to do more merit; Simultaneity factor resistance is excessive, near chute mouth, floating burnt situation easily occurs, can block whole chute, whole operation is stopped production time serious.
Summary of the invention
Technical problem to be solved by this invention is: the size how providing the timely detection system resistance of a kind of dry coke quenching recycle gas resistance monitoring method, performs reply in advance and prepares.
The technical solution adopted in the present invention is: a kind of dry coke quenching recycle gas resistance monitoring method, carries out according to following step:
Step one, measures the unit time wind supply quantity Q of recirculation blower
air quantitywith the pressure P in recirculation blower exit
blower fanbe input to electronic monitoring device.
Step 2, electronic monitoring device receives the unit time wind supply quantity Q measuring recirculation blower
air quantitywith the pressure P in recirculation blower exit
blower fanafter, with P
blower fan/ Q
air quantityvalue P as with reference to value, the display unit of electronic monitoring device shows, and if P is greater than set(ting)value P
setting, then electronic monitoring device sends guard signal.
The invention has the beneficial effects as follows: the present invention is by the unit time wind supply quantity Q to recirculation blower
air quantitywith the pressure P in recirculation blower exit
blower fanmeasurement carry out the size of evaluating system resistance, thus understand the change of recycle gas systemic resistance in time, perform reply in advance and prepare.
Embodiment
Electronic monitoring device of the present invention comprises cpu, display unit, warning device, the unit time wind supply quantity Q of recirculation blower
air quantitycan be determined by the actual speed of the specified wind supply quantity of recirculation blower and recirculation blower, determine the unit time wind supply quantity Q of recirculation blower
air quantityafterwards end value is input to the cpu of electronic monitoring device, by being arranged on the tensimeter in recirculation blower exit the pressure P in recirculation blower exit
blower fanmeasure, end value is input to the cpu of electronic monitoring device, the cpu of electronic monitoring device calculates P=P
blower fan/ Q
air quantitythen the P that puts on airs is shown by the display unit of electronic monitoring device, finally P and set(ting)value P
settingcompare, if P is greater than set(ting)value P
setting, then electronic monitoring device cpu sends guard signal to warning device.
After following the tracks of P value, can effectively controlled circulation gas system resistance in scope suitably.
1, recycle gas systemic resistance is less, can reduce dust-laden recycle gas to equipment each in system, pipeline wearing and tearing.
2, recycle gas systemic resistance is less, and in equal air quantity situation, recirculation blower overcomes resistance work and will lack, and can reach the object of economize on electricity power saving, is beneficial to the economical operation of whole system;
3, recycle gas systemic resistance is less, and near chute mouth, pressure surge also can diminish, like this for preventing floating burnt generation from also having certain benefit,
4, recycle gas systemic resistance is less, and when recycle gas and coke heat, heat transfer effect can be improved, and improves heat exchange efficiency, adds the burnt steam production of ton and generated energy.
