Abstract

The invention discloses a system and a method for controlling oxygen blowing control for a calcium carbide furnace. The system comprises a detection device, an executing mechanism and a controller. The detection device is used for detecting the current state of the calcium carbide furnace; the executing mechanism is used for controlling oxygen spray used by the calcium carbide furnace; and the controller is separately connected to the detection device and the executing mechanism, and controls the executing mechanism to execute a corresponding action according to the current state after starting to execute the oxygen spraying operation of the calcium carbide furnace, so as to finish the oxygen spraying work. The system can realize automatic control of the system for controlling oxygen blowing control for the calcium carbide furnace, so that the production cost of calcium carbide is effectively lowered. The energy structure is improved, and the system has the characteristics of being stable, safe and efficient, the automation and reliability of the system are improved, and the system is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of calcium carbide smelting, in particular to a control system and method for using oxygen injection in a calcium carbide furnace. Background technique [0002] In the related technology, the production methods of calcium carbide include aerobic thermal method and electrothermal method. Generally, electrothermal method is used to produce calcium carbide. The main production process is: firstly, the lime meeting the calcium carbide production demand is crushed, screened and mixed with carbon-containing raw materials (coke, Anthracite or petroleum coke) are batched according to the specified ratio, fed into the calcium carbide furnace through the delivery pipe, and then the electrode is inserted into the calcium carbide furnace and energized, and the heat generated by the resistance thermal reaction of the electrode arc pad and the furnace charge heats the furnace charge to 1900 -2200°C, the furnace material r...
