Embodiment Construction

[0050] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0051] figure 1 It is the overall structure diagram of the automatic optimization control system of the cement firing system in an embodiment, as shown in the figure. A cement burning system includes a preheater, a decomposition furnace, a rotary kiln, and a grate cooler. After the raw meal enters the preheater for heating, it is sent to the decomposition furnace to decompose the raw meal into free oxidation at high temperature. Calcium generates cement clinker, which is output after being cooled by the grate cooler.

[0052] Among them, the raw meal is a material that is made of lime-based raw ...

Abstract

The invention relates to a cement firing system. The system comprises a preheater, a decomposing furnace, a rotary kiln and a grate cooler, raw material enters the preheater to be heated and then is conveyed to the decomposing furnace to decompose the raw material into free calcium oxide at high temperature to generate cement clinker, and the cement clinker is output after being cooled by the grate cooler. The invention further discloses an automatic optimizing control system of the cement firing system. According to the cement firing system and the automatic optimizing control system thereof,24-hour uninterrupted operation under normal process conditions can be realized, for important process parameters such as the temperature of the decomposing furnace, the optimal set value is calculated through automatic optimization according to an economic target given by a user without depending on the set value given by an operator, and the purposes of increasing the yield, reducing the specific energy consumption, stabilizing the quality and improving the economic benefits of cement production enterprises are achieved.

Description

Technical field [0001] The invention relates to the field of cement production, in particular to a cement burning system and an automatic optimization control system thereof. Background technique [0002] The cement production process includes three procedures: cement raw material grinding, cement firing and cement grinding. Among them, the process of cement firing is: [0003] 1. When the raw meal is suspended, the hot air drawn from the rotary kiln by the high-temperature fan is used for heat exchange to realize the drying and heating of the material; [0004] 2. The CaCO3 component in the preheated cement raw meal is decomposed into CaO in the decomposition furnace, and under the high temperature conditions of the rotary kiln, it undergoes various complex reactions to form cement clinker; [0005] 3. The cement clinker is cooled by a grate cooler and heat is recovered (secondary air entering the kiln / tertiary air entering the calciner). [0006] The problems in the automatic contro...
