Abstract

The invention discloses a double-hearth lime kiln suspension cylinder temperature monitoring method and system and a storage medium. The double-hearth lime kiln suspension cylinder temperature monitoring method comprises the following steps that S1, the air temperature ti of each temperature measuring point i in an airflow cooling flow channel of a suspension cylinder is obtained; s2, the estimated average wall surface temperature T'w of the suspension cylinder is obtained through calculation; s3, calculating logarithmic temperature rise aj of the temperature measurement interval j; and according to the logarithmic temperature rise curve corresponding to the logarithmic temperature rise aj, determining that the logarithmic temperature rise aj deviating from a preset threshold value on the logarithmic temperature rise curve is abnormal temperature rise, and obtaining a temperature measurement interval corresponding to the abnormal temperature rise as an overtemperature area. According to the double-hearth lime kiln suspension cylinder temperature monitoring method, temperature rise signals between local overtemperature areas are dominantly changed by using a mean value checking method and logarithmic temperature rise changes, the local overtemperature areas are determined, the capture and monitoring of the local overtemperature of the suspension cylinder are more sensitive, timely early warning can be provided for a production field, and the production efficiency is improved. Therefore, the service life of the suspension cylinder is effectively prolonged.

Description

[0001] 1 in the technical field [0002] The invention relates to the technical field of temperature monitoring of a suspended cylinder of a double-bore lime kiln, in particular to a temperature monitoring method, system and storage medium of a suspended cylinder of a double-bore lime kiln. 2 background technology [0003] Double chamber lime kiln is one of the most advanced lime production equipment at present, widely used in the production of industrial lime and construction lime. It is mainly composed of two vertical kiln chambers that are mirror images of each other. During the production process, pulverized coal and combustion-supporting air are supplied to one side of the kiln chamber to form a high-temperature environment, so that the limestone in the kiln chamber is pyrolyzed, which is called the calcination chamber; One side of the kiln chamber is filled with materials at normal temperature, and at the same time, the high-temperature flue gas formed in the combustion ...
