Embodiment 1

[0093] In the embodiment of the present disclosure, based on the principle of energy balance and material balance, the component increment in the molten pool of the reaction furnace, the height of the slag layer in the molten pool and the height of the metal layer in the molten pool are predicted, and the predicted values ​​are corrected, Specific steps are as follows:

[0094] Step 1, calculate the amount of reaction product:

[0095] (1) Obtain the energy balance formula: the heat of the reactor includes the input electric energy Q E , Feed heat Q M , Flue gas heat loss Q G and furnace body and other stray heat loss Q L , based on the principle of energy balance, the expression of the energy balance formula is obtained as follows:

[0096] Q E +Q M =Q F +Q G +Q L (1)

[0097] Such as Figure 9 As shown, a reactor structure 900 is provided. In the reaction furnace 908, on the one hand, the load cell in the feeding bin 902 is used to measure the feed amount W M ,...

Embodiment 2

[0152] In the embodiment of the present disclosure, the process of predicting the height of the molten layer is as follows:

[0153] (1) After the slag discharge or material discharge is completed, measure the actual slag discharge or material output to obtain the slag value of the actual slag discharge and the calculated slag discharge, or the actual discharge and calculation The material quantity value of the output quantity, record the input electric energy, the input heat and the heat loss of the flue gas, which are used for the iterative training of the neural network model.

[0154] (2) Clear the height of the slag layer or the height of the metal layer in the reaction furnace, clear the running time, and start a new period of prediction of the molten layer height.

[0155] (3) Real-time measurement of feed temperature, feed amount, flue gas temperature, flue gas flow and input electric energy.

[0156] (4) Calculate the amount of slag and material discharged during the...

Abstract

The invention provides a reaction furnace control method and device, a medium and electronic equipment. The reaction furnace control method comprises the following steps of determining reaction heat of a material according to input electric energy, feeding heat and loss heat of a reaction furnace; determining the amount of reaction products in the reaction furnace according to the reaction heat; determining the slag proportion in the reaction product amount so as to determine the slag discharging amount and / or the discharging amount; and controlling the deslagging process of the reaction furnace according to the deslagging amount, and / or controlling the discharging process of the reaction furnace according to the discharging amount. Through the technical scheme provided by the embodiment of the invention, the control efficiency and the control accuracy of the deslagging process or the discharging process are improved, the energy efficiency utilization rate is improved, the product quality is also improved, and the energy consumption cost is further reduced.

Description

technical field [0001] The present disclosure relates to the technical field of smelting, and in particular, relates to a control method of a reaction furnace, a control device of the reaction furnace, a computer-readable storage medium and electronic equipment. Background technique [0002] As an important reaction furnace for smelting, submerged electric furnace uses electrodes to load current to materials to generate heat to achieve smelting purposes. The submerged heat electric furnace receives the heat material generated by the upstream process, and heats the material through the conversion of electric energy into heat energy, so that the material is melted, reacted and separated in the furnace. With the progress of the reaction process in the submerged electric furnace, a slag layer and a metal layer are gradually formed in the furnace. Therefore, it is particularly important to timely control the slag discharge process and material discharge process to obtain the acc...
