Embodiment 1

[0031] In this embodiment, the components of the conventional known structures are not described and shown in the figure.

[0032] Such as figure 1 As shown, the industrial kiln intelligent control system disclosed in this embodiment, the industrial kiln intelligent control system, includes the main body of the cement kiln and the online flue gas analyzer of the analysis furnace connected to the main body, and the online flue gas analyzer of the rotary kiln smoke chamber. Analyzer, high-temperature fan, tertiary air valve, raw material detection analyzer, coal quality detection analyzer, kiln head scale and kiln tail scale, set cement kiln control system and industrial kiln intelligent control system to interact with the main body of the cement kiln connected, the control and sampling signals of the industrial kiln intelligent control system and the cement kiln control system are transmitted in a communication manner; the control signals and sampling signals of the industrial ...

Embodiment 2

[0038] The complete set of equipment for industrial furnace intelligent control system is divided into: rotary kiln combustion status sampling system, calciner combustion status sampling system, industrial furnace intelligent control system, host computer monitoring system, and remote monitoring system. Install an online flue gas analyzer at the outlet of the cement kiln calciner to measure the actual combustion state of the cement kiln calciner. The measurement signals are: oxygen content signal and carbon monoxide signal. Install an online flue gas analyzer in the tail smoke chamber of the cement kiln to measure the actual combustion state of the cement kiln rotary kiln. The measurement signals are: oxygen content signal and carbon monoxide signal. An industrial kiln intelligent control system (central control cabinet) is installed next to the cement kiln control system, and the control and sampling signals of the industrial kiln intelligent control system and the cement kiln...

Abstract

The invention discloses an intelligent control system of an industrial furnace. The intelligent control system comprises a cement furnace body, and a decomposition furnace online smoke analyzer, a rotary kiln smoke chamber online smoke analyzer, a high-temperature fan, a tertiary air valve, a raw material detecting analyzer, a coal quality detecting analyzer, a kiln head coal scale and a kiln tail coal scale connected with the body; the intelligent control system of the industrial furnace is characterized by being connected with the cement furnace body, transmits control and sampling signals of a traditional cement furnace control system in a communication manner, and sends the control and sampling signals to the traditional cement furnace control system; and the traditional cement furnace control system sends signals needed by the intelligent control system of the industrial furnace to the intelligent control system of the industrial furnace.

Description

technical field [0001] The invention relates to the technical field of cement kiln control, in particular to an intelligent control system for an industrial kiln. Background technique [0002] Cement kilns include rotary kilns and calciners. Rotary kilns refer to rotary calcining kilns (commonly known as rotary kilns), which belong to the category of building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kilns are mainly used for calcining cement clinker, which can be divided into two categories: dry production cement kiln and wet production cement kiln. Metallurgical and chemical kilns are mainly used for magnetization roasting of lean iron ore in iron and steel plants in the metallurgical industry; oxidative roasting of chromium and nickel-iron ore; roasting of high-alumina bauxite in refractory plants and clinker and aluminum hydroxide in aluminum plants; roasting o...
