Referring to fig. 1, a schematic flow chart of a temperature control method of a pyrolysis verification system according to an embodiment of the present invention is shown. In the embodiment of the invention, the temperature control method of the pyrolysis verification system is mainly applied to a pyrolysis furnace, the pyrolysis furnace comprises a plurality of temperature control areas, and the method comprises the following steps:
and S110, acquiring the current temperature of each temperature control area.
And S120, generating control parameters of each temperature control area based on the current temperature and the preset target temperature.
In the embodiment of the invention, the pyrolysis furnace is divided into a plurality of temperature control areas, and the expected temperature required to be reached in each temperature control area is correspondingly different according to different process requirements. After the current temperature of each temperature control area is obtained, corresponding control parameters can be generated according to the deviation between the current temperature and the target temperature preset in each temperature control area. Wherein the current temperature of each temperature control zone can be obtained by a temperature sensor such as a thermocouple or the like.
And S130, adjusting the temperature of each temperature control area based on the control parameters.
Specifically, the pyrolysis furnace comprises an electric heating temperature control area and a fuel gas heating temperature control area, and the adjusting of the temperature of each temperature control area comprises adjusting the temperature of the electric heating temperature control area and adjusting the temperature of the fuel gas heating temperature control area. It can be understood that the electric heating temperature control area and the gas heating temperature control area can be both provided in a plurality of numbers, in this embodiment, the pyrolysis furnace is provided with twelve temperature control areas, wherein one to six areas are electric heating temperature control areas, and seven to twelve areas are gas heating temperature control areas.
In the embodiment of the invention, the pyrolysis furnace is divided into an electric heating temperature control area and a gas heating temperature control area, and the temperature is controlled by electric heating and gas heating modes respectively. The combined heating temperature control mode of electric heating and gas heating can avoid the problem of abnormal temperature caused by amplitude limiting, uneven distribution of resistance of a heating body and the like of single electric heating, and the problem of influence on the temperature distribution of the whole thermal field due to overhigh or overlow temperature of the whole area caused by aging of a single heating body, thereby overcoming the defects of high electric heating power, high power consumption, high requirement on site water resistance and change of resistance value of a resistance wire along with the change of temperature; meanwhile, the condition that the temperature fluctuation is large and the overshoot is particularly generated at the low-temperature stage due to a single fuel gas heating mode is avoided. The combined heating mode of electric heating and gas heating is adopted, and the optimal combined heating mode is set through different processes, so that the uniform temperature field is favorably realized, and the process requirements are better met.
In specific implementation, in step S120, a PID algorithm is used to generate control parameters for each temperature control zone. In an embodiment of the invention, the PID controller is concerned with setting the proportional, integral and derivative values, and possibly the best control of a particular process. When the measured temperature collected by the thermocouple deviates from the expected set value, the PID controller can perform proportional (P), integral (I) and differential (D) operations according to the deviation of the measured signal and the set value, so as to output a certain appropriate control signal to the actuating mechanism, and the real-time temperature follows the set value, thereby achieving the effect of automatic temperature control. The proportional operation is a proportional relation between the output control amount and the deviation. The larger the set value of the proportional parameter P, the lower the sensitivity of control, and the smaller the set value, the higher the sensitivity of control, for example, when the proportional parameter P is set to 4%, indicating that the measured value is 4% off the given value, the output control amount is changed to 100%. The purpose of the integration operation is to eliminate the offset. The integral action moves the control quantity in the direction to eliminate the deviation only if the deviation exists. The integration time is a unit representing the integrated action intensity. The shorter the integration time is set, the stronger the integration effect. For example, if the integration time is set to 240s, it is indicated that 240s is required for the output amount of the integration action to be equal to the output amount of the proportional action for a fixed deviation. The proportional action and the integral action are correction actions on the control result, and the response is slow. The differential action is supplemented in order to eliminate its disadvantages. The derivative action corrects the output quantity according to the speed of deviation to quickly restore the control process to the original control state, the derivative time is a unit representing the strength of the derivative, and the longer the derivative time set by the meter is, the stronger the correction by the derivative action is.
