Three-end voltage stabilization type temperature warning system for carbon roasting furnace

Abstract

The invention discloses a three-end voltage stabilization type temperature warning system for a carbon roasting furnace. The system mainly consists of a processor, an A / D conversion module and a displayer connected with the processor, and a temperature sensor connected with the A / D conversion module. The system is characterized in that the processor is connected with a three-end voltage stabilization warning circuit; and the three-end voltage stabilization warning circuit consists of a transformer T, a voltage input circuit, a temperature signal input circuit and a warning circuit. The system is simple in structure and low in cost, can immediately give an alarm through the three-end voltage stabilization warning circuit when the smoke temperature is overhigh, and can timely treat dangers to prevent the combustion and caused fire or even the explosion risk due to overheated smoke, so that the production safety is guaranteed, and the system is suitable for promotion and application.

Description

technical field [0001] The invention relates to an alarm system, in particular to a three-terminal voltage-stabilized 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, it is usually necessary ...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of low sensitivity and unresponsiveness of the alarm system currently used in carbon roasting furnaces, which cannot immediately detect dangerous situations, and provide an alarm system that is not only simple in structure, but also low in cost, and can immediately detect super high flue gas temperature. Hidden dangers, so as to deal with dangerous situations in time
