The core of the process control system for treating the hazardous waste is the control of the incineration process, namely, the flow of various fuels and air is controlled to adjust the combustion process, the combustion temperature is ensured to be stabilized at a set value, and the fluctuation does not exceed the allowable deviation, so that the incineration process is ensured to meet the temperature required by the process. If the temperature is lower than the required temperature, the process is difficult to carry out next procedure and the quality of waste treatment is affected; if the furnace temperature is higher, the fuel is wasted, the furnace life is reduced, the burning loss is increased, and even the equipment is over-burnt and scrapped.
The conventional temperature control system utilizes the deviation of the actual measured value and the preset value to adjust the waste treatment amount and the combustion-supporting fuel amount so as to realize the constant temperature of the hearth. However, the heating value and water content of the dangerous waste to be treated are changed violently, and the change trends of the charging and the temperature are not consistent, so that the control effect in the actual treatment process is not ideal.

FIG. 2 is a block diagram of a hazardous waste combustion system to which embodiments of the present disclosure are applied.
Referring to fig. 2, hazardous waste combustion system 200 may include three major parts of feed module 21, combustion module 22, and flue gas treatment module 23, as well as processor 24 coupled to combustion module 22 and memory 25 coupled to the processor.
The feeding module 21 may include a feeding port for natural gas, high calorific value waste liquid, low calorific value waste liquid, barreled medical waste, bulk waste and the like, and a feeding device such as a lifter, a feeding mechanism, a material pit, a crusher, a traveling crane and the like.

The processor 24 is used for executing the control method shown in fig. 1 to control the system 200 to operate, and the memory 25 is used for storing codes for executing the control method shown in fig. 1.
In order to better control the combustion efficiency, in the embodiment of the disclosure, the rotary kiln is used as a first position for controlling the temperature of the rotary kiln, the rotary kiln burner is used as a first position burner for controlling the temperature of the rotary kiln, the second combustion chamber is used as a second position for controlling the temperature of the rotary kiln, and the second combustion chamber burner is used as a second position burner for controlling the temperature of the rotary kiln.
That is, the target temperature of the rotary kiln and the target temperature of the secondary combustion chamber, which can maximize the combustion efficiency and minimize the fuel waste, can be determined by calculation in advance according to the material usage and the feed amount, and then the gas flow of the rotary kiln burner and the gas flow of the secondary combustion chamber, which can control the temperature of the rotary kiln and the temperature of the secondary combustion chamber, are determined according to the preset data processing model, so that the temperature of the rotary kiln and the temperature of the secondary combustion chamber can reach the calculated target temperature of the rotary kiln and the calculated target temperature of the secondary combustion chamber by adjusting the gas flow of the rotary kiln burner and the gas flow of the secondary combustion chamber burner.
Because the target temperature is calculated in real time and the model parameters of the data model are determined, the data model can determine the gas flow of the combustion chamber at each position in real time, and has the advantages of high instantaneity, high accuracy and the like.
In the embodiment of the present disclosure, the used preset data processing model is a data processing model improved based on a cari (Controlled Auto-Regressive Integrated Moving Average) model:
wherein A is1(x)、A2(x)、B11(x)、B21(x)、B12(x)、B22(x)、C1(x)、C2(x) X are model parameters, y1Is a first position target temperature, y2Is the second position target temperature u1For the first position burner gas flow u2For the second position burner gas flow, epsilon1、ε2Are all mean zero and variance σ2K is the control order.

The white noise parameter can be set by the model application personnel (for example, set as a constant) to better adjust the data processing model so that the data processing model can be better adapted to different systems and solve the problems of multivariable coupling, pure hysteresis, parameter time variation and the like existing in the controlled object.
The data processing model applied by the embodiment of the disclosure is established based on system identification. The system identification is to determine a model equivalent to the system under test from a class of models based on input and output data. The system identifies three elements-data, model class, and criteria. The main contents identified by the system include: identifying experimental designs, model structure determination, parameter estimation, model verification, and the like. The classical method of system identification is combined with the classical control theory. The classical control theory analyzes a single-input single-output system, and common system models are a weight function, a transfer function and a frequency characteristic. The classical method of identification is usually based on experimental determination of non-parametric models of the system, such as step response, impulse response, and frequency response.
