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, an estimated heat transfer constant const is obtained; s3, obtaining the proportional temperature rise aj of the temperature measurement interval j; and according to a proportional temperature rise curve corresponding to the proportional temperature rise aj, determining that the proportional temperature rise aj deviating from a preset threshold value on the proportional temperature rise curve is abnormal temperature rise, and obtaining an area corresponding to the abnormal temperature rise as an overtemperature area. According to the method for monitoring the temperature of the double-hearth lime kiln suspension cylinder, the abnormal temperature rise is dominantly changed through the mean value checking method and the change of the proportional temperature rise, the local overtemperature area is determined, capturing and monitoring of the local overtemperature of the suspension cylinder are more sensitive, and timely early warning can be provided for a production site, so that the service life of the suspension cylinder is effectively prolonged.

Description

Method, system and storage medium for temperature monitoring of hanging cylinder of double-chamber lime kiln 1 in the technical field The present invention relates to the temperature monitoring technical field of double-chamber lime kiln hanging cylinder, particularly, relate to a kind of double-chamber lime A kiln hanging cylinder temperature monitoring method, system and storage medium. 2 Background technology Double-chamber lime kiln is one of the most advanced lime production equipment at present, and is widely used in industrial lime and building stone. Ash production. It is mainly composed of two vertical kiln chambers that are mirror images of each other. During the production process, pulverized coal and coal powder are supplied to one side of the kiln chamber. The combustion-supporting air forms a high-temperature environment, and the limestone in the kiln is decomposed at high temperature, which is called the calcining chamber; the other side of the kiln is ...
