Three-end voltage-stabilizing filtering resonant-type temperature alarm system used for carbon furnace

Abstract

The invention discloses a three-end voltage-stabilizing filtering resonant-type temperature alarm system used for a carbon furnace. The three-end voltage-stabilizing filtering resonant-type temperature alarm system is mainly composed of a processor, an A / D conversion module and a display which respectively are connected with the processor, and a temperature sensor connected with the A / D conversion module. The three-end voltage-stabilizing filtering resonant-type temperature alarm system is characterized in that the processor is further connected with a three-end voltage-stabilizing alarm circuit, the three-end voltage-stabilizing alarm circuit is further connected with a filtering resonant circuit, and the three-end voltage-stabilizing alarm circuit is composed of a transformer T, a voltage input circuit, a temperature signal input circuit and an alarm warning circuit. The three-end voltage-stabilizing filtering resonant-type temperature alarm system is simple in structure and low in cost, and the three-end voltage-stabilizing alarm circuit immediately gives an alarm when the temperature of smog gas is extremely high, so that dangerous conditions can be processed in time, a fire and even the danger of explosion caused by the extremely high smog gas are prevented, the production safety is ensured, and the three-end voltage-stabilizing filtering resonant-type temperature alarm system is suitable for popularization and utilization.

Description

technical field [0001] The invention relates to an alarm system, in particular to a three-terminal voltage stabilizing filter resonance type temperature alarm system for a carbon roasting furnace. Background technique [0002] Carbon roasting furnaces usually use petroleum coke and pitch as raw materials. Under high temperature conditions, the roasting workshop completes the roasting of vibration-shaped raw carbon blocks into qualified cooked carbon blocks. The temperature of raw carbon block is 200-1200°C during the roasting process, and a large amount of roasting flue gas is released during this process. The main components of the roasting furnace flue gas are asphalt fume, tar and various combustible dust, and the flue gas outlet temperature is as high as 900°C. At high temperature, these flue gases must be discharged from the flue in time, otherwise it is easy to overheat and burn, and even cause an explosion. In order to facilitate the detection of hidden situations, i...
