Abstract

The invention relates to the technical field of temperature measurement devices using thermoelectric elements, in particular to an automatic monitoring system for the oven drying temperature of a coke oven. The automatic monitoring system comprises a thermocouple (1), a compensating lead wire (2), a temperature acquisition module (3), a shielding data line (4), an industrial power supply (5), a power supply conducting wire (6) and an upper computer (7). The invention is characterized in that the automatic monitoring system additionally comprises a base (8) and an acquisition box (9), the thermocouple (1) is connected with the temperature acquisition module (3) inserted on the base (8) through the compensating lead wire (2), the shielding data line (4) is connected with the acquisition box (9), a converter (10) and the upper computer (7), the acquisition box (9) is connected with a power supply interface through the power supply conducting wire (6), the acquisition box (9) is connected with the upper computer (7) and the industrial power supply (5), and a temperature monitoring control program is resided in the upper computer (7). The invention has the advantages that the detection precision is high and the oven drying quality is improved.

Description

technical field [0001] The invention relates to the field of temperature measuring devices using thermoelectric elements, in particular to an automatic monitoring system for coke oven oven temperature. Background technique [0002] Coke oven, also known as coke oven, is coal coking equipment and the key to coking technology. The body of a modern coke oven consists of five parts: a foundation platform, a regenerator, a chute, a combustion chamber and a furnace roof, and is mainly made of silica bricks. Before the coke oven is put into production, it must be baked. The quality of the oven is very important for the stable production, high production and long life of the coke oven. During the drying process, there are different requirements for the heating rate according to the different stages of the furnace temperature. It usually takes about 2 months from room temperature to 800 °C, especially about 1 month from room temperature to 300 °C, and the temperature accuracy during...
