Embodiment 1

[0050] A method for intelligently controlling the melting temperature field of a glass melting furnace, comprising the following steps:

[0051]Step S1, by controlling the total amount of fuel, adjust the fuel amount of each small furnace at the same time; adjust the fuel ratio distribution of each small furnace until the melting temperature field of the glass melting furnace is stable; at this time, the hot spot temperature is the standard temperature, and the position of the bubble boundary is the standard temperature Location;

[0052] Step S2, obtaining the hot spot temperature change of the glass melting furnace, and adjusting the total amount of fuel according to the hot spot temperature change;

[0053] When the hot spot temperature decreases, the total amount of fuel is increased;

[0054] When the hot spot temperature increases, reduce the total amount of fuel;

[0055] Usually, the temperature change of the large dome temperature point corresponding to the small fu...

Embodiment 2

[0070] A system for intelligent control of melting temperature field of glass melting furnace, such as figure 2 As shown, the system includes a temperature sensor, a bubble boundary monitoring device, a control device and a regulating device;

[0071] The temperature sensor is electrically connected to the control device, and sends a temperature signal to it; the bubble boundary monitoring device is electrically connected to the control device, and sends a bubble boundary position signal to it;

[0072] The control device includes a temperature control module, a bubble boundary module and a judgment module;

[0073] The temperature control module receives the temperature signal of the sensor, and sends a first decrease signal to the judgment module when it is determined that the temperature rises; and sends a first increase signal to the judgment module when it is judged that the temperature drops;

[0074] The bubble boundary line module receives the bubble boundary line po...

Abstract

The invention relates to the technical field of float glass production and manufacturing, in particular to a method for intelligently controlling a melting temperature field of a glass melting furnace. Comprising the following steps that S1, by controlling the total amount of fuel, the fuel amount of each small furnace is adjusted at the same time; adjusting the fuel proportion distribution of each small furnace until the melting temperature field of the glass melting furnace is stable; s2, acquiring the hot-spot temperature change of the glass melting furnace, and adjusting the total amount of fuel according to the hot-spot temperature change; when the hot spot temperature is reduced, the total fuel amount is increased; when the hot spot temperature rises, the total fuel amount is reduced; s3, the moving direction of the bubble boundary is obtained, and the total fuel amount is adjusted according to the hot spot temperature change and the bubble boundary moving direction; when the temperature of the hot spot drops, the bubble boundary line moves towards the feeding port to reduce the total amount of fuel; when the hot-spot temperature rises, the bubble boundary line moves towards the clarification area, and the total fuel amount is increased.

Description

technical field [0001] The invention relates to the technical field of float glass production and manufacturing, in particular to a method for intelligently controlling the melting temperature field of a glass melting furnace. Background technique [0002] With the wide application of intelligent technology in the traditional manufacturing industry, the intelligentization of glass manufacturing has become imperative. The glass melting furnace is the "heart" of glass production, and the control of the melting temperature field of the melting furnace is the core and difficulty. In float glass production, the control of the melting furnace system emphasizes "stable temperature, stable kiln pressure, stable liquid level, stable material stack and bubble boundary", in order to achieve operability, it is designed into many subsystems, such as kiln pressure control system And liquid level control system, has been able to achieve intelligent control, but the temperature field contro...
